It is different from the traditional factory where the molten iron rushes and the heavy smoke billows. In Wuxi, such a “green manufacturing†engine plant with green plants, floral fragrances, spacious pavements, and clean factory areas is gradually emerging. It is the base of Xiehai heavy-duty diesel engine Huishan. As a national demonstration unit for energy conservation and emission reduction, what is the "green factory" in this "green factory"?

In the past decade, Xichai has invested hundreds of millions of yuan in the construction of environmental protection facilities. The pioneering use of automated conveyor equipment reduces manual transfer links and costs, and increases production efficiency.
In terms of low-carbon, we will take the lead in using ground source heat pump technology and natural gas heating and drying to achieve low-carbon production. Cumulative power savings of more than 17 million kW·h and reduction of 5746 tons of carbon emissions.
In the aspect of emission reduction, through the introduction of equipment for centralized circulation of cooling fluids and equipment for centralized suction of mist and dust, the cumulative reduction of non-methane total hydrocarbon emissions by approximately 5.04 tons, reduction of wastewater discharge by approximately 150,000 tons, and reduction in COD emissions by approximately 11%. Ton.

In respect of energy conservation, the daily sewage treatment capacity of the plant has been upgraded from the original 2,700 cubic meters/day to 3,200 cubic meters/day by renovating the sewage pipe network. It is estimated that Xichai uses 400,000 tons of reclaimed water each year, which saves more than RMB 1 million in water charges in only one year.

For the first time in China, the application of cold test technology for heavy-duty diesel engine production lines is in Xichai. Compared with the traditional hot test technology, the cold test technology technology greatly shortens the product delivery cycle, at the same time, the school bus no longer consumes diesel fuel, and the total diesel fuel savings of about 2,500 tons, and does not require a lot of water, electricity, gas supply, not to mention Exhaust gas emissions.

In addition, Xichai continues to increase investment in advancing the smart factory to realize the interconnection and intercommunication of information across the entire plant and achieve the true meaning of “device interconnection, data exchange, and process interactionâ€. In 2016, FAW Jiefang Xichai Intelligent Manufacturing Project was short-listed by the Ministry of Industry and Information Technology “2016 Smart Manufacturing Pilot Demonstration Projectâ€.

In terms of automotive products, the “EGR+DOC+DPF†technology route is adopted to strictly control pollutant emissions. The cumulative amount of carbon monoxide emitted from the Xichai engine decreased by 28% year-on-year, cumulative hydrocarbon emissions decreased by 30% year-on-year, and cumulative PM particulate matter decreased by 95% year-on-year, effectively reducing emissions of exhaust gas to the atmosphere.

In terms of remanufactured products, Xichai has established an engine remanufacturing base. The annual added value of recycled products is close to 125 million yuan, saving 7 million kW·h, and reducing carbon dioxide emissions by 300 tons, which has contributed to the development of circular economy.
In the future, FAW Jiefang Xichai will always adhere to the development direction of “green manufacturingâ€, strive hard and advance vigorously, and make new contributions to the harmonious development of people, vehicles and society!
Readings:Canway multi-purpose tent groups are developed for those need large and different functional areas in fields. Typically, their fields of use involve medical care in fields, long-term military activities, team buildings and so on. These activities often need several functional areas in tents. For instance, the medical tent group include logistics support area, medical treatment area, decontamination area and so on These area tent groups constitute a hospital tent. These area tents are connectable and they can connect with each other according to the functional requirements. Inflatable tents and metallic frame tents are both suitable for the tent groups.
Due to the long-term exposure in fields, the materials for these tents are high quality so that they can bear the long-term wind, rain and sun, even snow. Canway multi-purpose tent groups can stand 30.0kg/sqm of snow load for one hour and the rainfall intensity more than 15.0mm per hour.
Canway has a professional design team who can deliver an ideal tent group solution when you are in need.
