Recently, from the 11th “National Top 100 Auto Parts Suppliers” Award Ceremony, good news was reported: FAW Jiefang Wuxi Diesel Engine Factory (hereinafter referred to as “FAW Xichai”) relied on sales, products, technology, management, service, and standards. The comprehensive advantages of the seven indicators of the brand and the successful adoption of the industry recommendation, initial evaluation, mass evaluation, expert re-evaluation, results disclosure and industry publicity assessment of the six levels, was rated as "National 100 Excellent Auto Parts Suppliers". , Reelection "excellent engine supplier" title.

In recent years, FAW Xichai has actively assumed social responsibility, promoted development transformation, management reform and product upgrading with independent innovation, and maintained a healthy and stable development with high energy efficiency and low energy consumption economic growth, not only ranked top in the industry in operating performance, but also in terms of The good image of the "Green Factory" has won widespread respect from society and it has become an industry model for energy-saving, low-carbon, high-quality and high-efficiency products.

Trinity, build green factory

The first step for FAW Xichai to build a green factory is to comprehensively promote cleaner production. The production line of FAW Xichai uses a large emulsion circulation system, which greatly reduces the use of emulsions and the production of waste emulsions. The use of wet processing technology eliminates the generation of industrial dust. At the same time, FAW Xichai's production department actively improved school bus technology, greatly shortened school bus time, reduced diesel consumption, optimized production organization in management, enhanced production efficiency, implemented full-load production, and reduced production days. Reduce energy consumption and pollutant emissions at the source. Through a series of measures, FAW Xichai successfully achieved clean production and controlled the generation of pollutants from the source.

The improvement of technology is another important means for energy-saving and emission reduction by FAW Xichai. “The work we do in this area is relatively successful in the industry. This year, we have improved the energy saving of the air compressor station, through the automation of air compressor clusters, cooling circulating water systems and peripheral auxiliary monitoring systems. Improve and reduce the gas power consumption of the air compressor station; implement energy-saving reform on the Tangnan Base Food and Beverage Center and use natural gas instead of steam; gradually eliminate high-energy-consumption motors to reduce equipment energy consumption; and use ground source heat pump air-conditioning system in the joint plant of the heavy machinery department Replaced traditional air-conditioning systems, to achieve a 44% reduction in power consumption; use alternating current power dynamometers instead of hydraulic dynamometers to achieve energy recovery; implementation of sewage pipe network reconstruction projects, to achieve the collection and classification of emulsion and ordinary sewage treatment, improve sewage Treatment efficiency, and reuse of treated reclaimed water at the same time to reduce the discharge of sewage; Heavy-duty department drying room uses clean energy natural gas combustion heating to replace the traditional steam heating, reduce pollution emissions; implementation of a number of noise control projects to reduce test run, empty Noise emission in high-noise areas such as pressure stations,” said the person in charge of the production department of FAW Xichai. The improvement and improvement of technology have provided strong support for the green production of FAW Xichai.

In addition to the control of the source and the support of technology, FAW Xichai is committed to implementing the grand mission of “national brands and high-end power”. It is also starting from management, through the establishment of energy systems and environmental management systems, and strengthening process monitoring. According to reports, the production department of FAW Xichai has signed the target responsibility letter with various departments, and decomposed the indicators into various production workshops and teams; at the same time, the FAW Xichai Production Department established an energy measurement network and an environmental monitoring network to implement energy data and pollutant emissions in real time. In addition to monitoring, in addition, the FAW Xichai Production Department has also formulated energy-saving work standards and environmental pollution emergency plans to control the energy use of key energy-consuming equipment and improve the emergency response capability of environmental pollution accidents.

The achievements made by FAW Xichai in the green production road in recent years are obvious to all. FAW Xichai's environmental monitoring data in 2014 showed that during the year, sewage from FAW Xichai's plants, processing dust emissions, assembly test, test room test, assembly paint, steam paint, plant boundary noise, etc. More than 100 data from 30 indicators are all in compliance with national emission standards. FAW Xichai has successfully achieved a grand transformation from a traditional machinery manufacturing plant to a large modern green factory.

Strictly control the three wastes and practice the concept of symbiosis

With the environmental protection issue being the focus of social concern, FAW Xichai located in the urban area has won the trust and respect of its neighboring citizens and units by virtue of its image of a “green factory” for decades. For the hard-earned trust and respect, FAW Xichai has been making unremitting efforts for decades.

In order to control the impact of the three wastes on the environment, FAW Xichai used noise insulation materials and soundproofed doors and windows to improve the sound absorption of school buses by improving the testing process. The noise source of the school bus test control room was controlled within 85 dB from the source. Reducing the impact of noise on the surrounding environment; By changing the processing technology, the original dry processing will be changed to wet processing to reduce industrial dust emissions. At the same time, precipitators are installed in the roughing and grinding machine workplaces to reduce dust emission to the atmosphere by controlling dust emissions from post processing within 8mg/m3. By installing a mist suction spray device at the spraying operation site, the diesel engine will be sprayed. The paint mist is absorbed into the spray tower, the benzene in the paint mist is controlled at 10 mg/m3, toluene and xylene are controlled within 100 mg/m3, and the influence of exhaust gas on the atmosphere is reduced.

FAW Xichai established a sewage treatment station with a processing capacity of 3,000 tons. It adopts a combination of physical and chemical and biochemical processes to treat production and domestic sewage. The treated part of the water is reused and the rest is discharged into the urban sewage pipe network. At the same time, through the transformation of the underground sewage pipe network, the original underground sewage pipe network was abolished, and a high-level sewage pipe network laying method using “multi-point collection - high-altitude transmission and discharge” combined with gravity and power drainage was adopted to fully realize the rain and sewage diversion in the plant area. . Solid wastes are classified, collected, and disposed of as recyclable, non-recyclable, and hazardous wastes, and hazardous wastes are entrusted to units with appropriate qualifications for disposal.

Through the effective control of industrial waste, FAW Xichai finally achieved mutual benefit and symbiosis in the surrounding areas, becoming a low-carbon factory located in the center of the city, and writing a beautiful picture of the harmonious coexistence of modern industry and modern urban life.

2014 was a year in which FAW Xichai made significant achievements in the green and low carbon production road. In the corporate environmental protection credit evaluation in 2014, FAW Xichai was rated as a green enterprise, which created a win-win situation for economic, social and environmental benefits. Wastewater, exhaust gas and noise emissions were monitored and the monitoring results met the standard. “Having earned honors and achievements is just a new starting point for our progress. In 2015, we will strive to achieve even lower emissions and higher energy efficiency.” The relevant person in charge of the FAW Xichai production department would be considered as a direct result of FAW Xichai. The best footnote to build a low-carbon factory.
