Anhui Huamao Group is a production and operation enterprise mainly based on spinning and weaving. Energy consumption is mainly electric power, accounting for about 85% of the total energy consumption, and other energy consumption is about 15% of total energy consumption, such as coal and oil.

As a pioneer enterprise in China's "a target=" _blank "href=" http://www.91se91.com/ "textile" /a "industry, Huamao has taken an important responsibility in building the goal of textile power.

In the course of many years of development, Huamao always takes energy conservation and emission reduction as a conscious action and basic work to reduce costs and enhance management.

Huamao persisted in promoting structural adjustment with technological innovation, promoting enterprise upgrading by technological pformation, actively implementing energy conservation and consumption reduction, promoting resource integration with enterprise culture, and further enhancing the enterprise's innovation capability.

we can say that Huamao's various strategies in energy saving and consumption reduction not only reduce the cost of production, but also make it more competitive in the process of competition with domestic and foreign counterparts.

energy saving system construction

"P > for a long time, Huamao persisted in saving energy and reducing consumption as a long-term work to strengthen management and promote development.

We should constantly improve the system building of energy management, strengthen scientific management of energy, adhere to the road of management and technological innovation, focus on improving energy efficiency of enterprises, promote technological innovation, enhance the competitiveness of enterprises, and promote the sustainable development of enterprises.

according to the introduction, aiming at the current situation and future work requirements of energy management, Huamao organized an energy management leading group to manage the energy work of the company.

As early as more than 10 years ago, Huamao focused on the development trend of the textile industry in the future, and determined that energy conservation and consumption reduction is one of the important basic tasks for the company's future strategic development, and the energy saving leading group, headed by the chairman of the board of directors, was set up. Under the jurisdiction of the energy conservation office, the energy conservation office fulfil the responsibilities of the energy conservation leading group and is responsible for the daily management of energy conservation in enterprises.

at present, Huamao requires all the production departments to set up the two level energy saving leading group of the head of the group, whose responsibility is to study, deploy and implement the energy conservation work of the unit, and to set up or designate the responsible departments and personnel of the energy management work, to organize and carry out the daily energy conservation work, and to study the overall energy saving work of the respective units.

change management consciousness

For more than a year, Huamao has always taken energy conservation and consumption reduction as the basic work to reduce costs and improve management, and actively publicize and mobilize various forms to raise staff's awareness of energy saving. P

The reporter noted that in Huamao, the functional departments and power plants concerned with energy conservation and consumption reduction will take the initiative to play a guiding role, and make full use of various forms such as visits, exchanges and guidance to provide technical support in depth in the production line.

Especially for the production department, the company organized front-line staff to find out the weak links of energy conservation and consumption reduction, and strengthen energy management measures to reduce energy consumption.

It is worth mentioning that after a series of basic and standardized management, Huamao employees can turn the consciousness of energy saving into conscious behavior. Starting from me, starting from saving a drop of water and once electricity, we have made our due contribution to the establishment of saving type Huamao.

it is understood that in order to do well in energy conservation and consumption reduction, Huamao Group has also established and improved three level management of energy saving: the first level is to set up a leading group for energy conservation, and the energy saving office is located at the equipment department, which is responsible for the daily management and coordination of energy conservation and consumption reduction; second, the branch and subsidiary companies have set up corresponding energy conservation leading groups, put energy conservation into daily work, and carried out KPI assessment on key energy saving indicators; third, the company has formulated a series of systems, such as "energy saving and consumption reduction management regulations", "energy saving reward and punishment system", "power consumption assessment system", "water consumption assessment system", "steam assessment system" and so on.

from the experience in the process of practice, the three level management system has achieved substantial results in the work of Huamao energy conservation and consumption reduction: the equipment department and the power plant each month organize the administrator to conduct special inspection, analysis and timely notification of the energy conservation of water, electricity, steam and gas, and supervise the rectification of the problems identified.

At the same time, various branches around the company system and assessment requirements, and formulated a series of inspection and assessment measures, implemented to the people, thereby ensuring the continuous and effective development of energy conservation and consumption reduction work.

in addition, in order to effectively promote energy saving and consumption reduction, new achievements have been made. In recent years, Huamao has also proposed finding short boards through innovative technology and management means, digging potential from technology and management, and plugging off water and vapour (gas) points which are not commonly used to reduce wastage.

In the process of optimizing production technology and rational deployment management, Huamao has achieved remarkable results in reducing energy consumption.

By the end of 2012, the comprehensive energy consumption of Huamao Group's annual output value of 10000 yuan decreased year by year, and fell by 16.16% at the end of fifteen.

In addition, Huamao's electricity consumption also showed a downward trend year by year, cotton yarn consumption decreased by 5.84% compared to the same period last year, and the consumption of grey fabrics decreased by 9.2% compared with the same period last year.

accelerate the pace of technological pformation

In order to further accelerate the pace of Huamao's energy saving and consumption reduction, the group decided to eliminate all outdated high energy consumption fans, pumps, refrigerating equipment and other equipment in the air conditioning room, and retrofit the exhaust system of the three spinning department production lines and the heat dissipation exhaust of spinning frames.

In winter, the energy consumption of the dust removal and return air and the heat dissipation and exhaust heat of the spinning workshop equipment is fully utilized to recycle the energy. This method solves the problem of heating in the pre spinning workshop in winter. At the same time, the relative humidity of the dust removal and return air is very low, and the reuse in the high humidity season can effectively reduce the relative humidity of the workshop and reduce the amount of chilled water used for dehumidification so as to achieve the purpose of energy saving.

it is understood that variable frequency technology in the variable conditions of air-conditioning system provides technical means for variable air volume regulation of air-conditioning systems in different seasons to achieve the goal of saving electricity. The application of this technology in Huamao Group has reduced the air conditioning power consumption by more than 20%.

AC variable frequency drive has many advantages. This technology can make the ordinary asynchronous motor realize stepless speed regulation, start current is small, reduce the power equipment capacity, start smoothly, reduce the impact of the machine, protect the mechanical equipment, protect the motor, reduce the maintenance cost of the motor, and have remarkable power saving effect.

Because of the above characteristics, AC variable frequency drive technology has begun to take the place of DC speed regulating device, and has become the development direction of modern electric drive.

reporter noted that before improving the technical equipment, the motor of Huamao production equipment was basically old Y series asynchronous motor, and the highest efficiency of Y series asynchronous new motor was about 91.5%. Because of the long use time, the efficiency gradually declined.

After introducing new energy-efficient asynchronous motors, the efficiency of the equipment can be maintained at around 93.3%. After replacing the motor, the actual detection will save 4.6% of the electricity.

at present, the new spinning and weaving and dyeing production line of Huamao Group has adopted new energy-saving and energy-saving materials. At the same time, the layout of the workshop is reasonably designed, and the air compressor station and workshop substation are arranged in the attached room of the main factory and close to the load center.

The company preferred to use advanced, efficient, high-energy and energy saving production equipment at home and abroad to promote efficient spinning process with short flow, large quantity and large draft. The main engine of the production line -- spinning frame, automatic winding machine, comber, blowing carding unit and so on, is at the leading level in China, no matter from technology, technology, equipment reliability, or energy consumption.

In the aspect of improving technology, Huamao has also made great efforts in the rational design of power supply and distribution system in electrical specialty, and has correctly chosen energy-saving products, and realized the economic operation of power supply and distribution equipment and electricity equipment through scientific management and reasonable organization of production. P

At present, the motor of the production process equipment and all kinds of auxiliary equipment of the group workshop are high efficiency motor with high efficiency, small noise and good protection performance.

in the production workshop, the piping layout of air conditioning, refrigeration and other systems strive to shorten the lines, reduce the loss of heat and heat. The insulation materials of pipelines and accessories shall first adopt materials with small thermal conductivity, large moisture resistance factor, low water absorption, small density and comprehensive economic benefits.

The air conditioning room adopts the spray method with high heat and humidity exchange efficiency to deal with the air, and the spray chamber adopts a low resistance component to reduce system resistance and reduce energy consumption.

While meeting the hygienic requirements, we should make full use of the return air to save energy.

After the improvement of P technology, Huamao introduced air pressure system with high and low pressure classification, namely, the spinning part and the pre weaving high pressure gas supply system and the loom air-jet loom low pressure gas supply system.

The air supply system of the weaving part under low pressure operation is installed with intelligent pressure controller to ensure the stability of the pressure. It can meet the needs of production and ensure the quality of products. At the same time, it reduces the pressure of the air pressure system and achieves the goal of energy saving.

it is worth mentioning that in order to further improve the technological process efficiency of the production process, Huamao company used condensate waste heat recovery device in the process of boiler operation to recover condensed water discharged from sizing machine and purchase condensate waste heat recovery device.

The condensate is collected and pported to the boiler house through stainless steel pipes, and is directly discharged to the softening tank for replenishment and heating of soft water.

in addition, Huamao Group also improved the technology of energy saving and consumption reduction for the mercerizing and singeing production line. By reconstructing and expanding the cistern, the condensate and cooling water produced in the production process were reused (for neutralization and pre-treatment water), and the weaving production line actively utilized the reclaimed water for boiler dedusting and washing and toilet washing, thus saving a lot of industrial water.
