The reporter learned from the Municipal Environmental Protection Bureau that 10 motor vehicle environmental inspection agencies have built 10 motor vehicle exhaust gas detection lines, and the qualification entrustment is under examination and approval. If the approval is passed, the environmental protection inspection qualification qualification certificate will be issued in the near future.
According to the relevant person in charge of the Environmental Protection Bureau's Pollution Prevention Division, in 2012, according to the latest standards and technical requirements of the national motor vehicle exhaust gas detection, the city has vigorously introduced social funds through market-oriented operation methods, and built four new automobile exhaust gas testing enterprises in the city. Among them, Shiyan City Anlong Motor Vehicle Safety Testing Co., Ltd., Shiyan City Aolong Motor Vehicle Safety Testing Co., Ltd., Shiyan Citizen Kangtai Environmental Protection Co., Ltd., and county (city) district have Danjiangkou City Golden Shield Motor Vehicle safety technical performance comprehensive testing A limited liability company.
It is understood that Shiyan Anlong Motor Vehicle Safety Testing Co., Ltd. is located at No. 3 Dalian Road, Shiyan City. There are 3 inspection lines (including 1 small gasoline line, 1 diesel-fuel hybrid line and 1 large diesel line); City Aolong Motor Vehicle Safety Testing Co., Ltd. is located at No. 94, Checheng West Road, Shiyan City. There are 2 inspection lines (including 1 small gasoline line and 1 diesel-mixed detection line); Shiyan Citizen Kangtai Environmental Protection Co., Ltd. is located in Shiyan City. There are 4 test lines at No. 28 Danjiang Road, Maojian District (including 2 diesel-mixed lines, 1 large diesel line and 1 small gasoline line).

Plate And Frame Heat Exchanger
Removable Plate Heat Exchanger (RPHE) is a type of heat exchanger composed of a series of plates which are held together with gaskets. The plates are connected in a plate pack that forms a sealed Pressure Vessel. The plate pack is assembled between a fixed frame plate and a movable pressure plate and is compressed by tightening bolts.
RPHEs are quite efficient as they have a large surface area compared to other heat exchangers. Heat transfer within the heat exchanger occurs between the plates and the fluids that flow through them. One fluid flows through the plate openings in each of them, and the heat transferred is determined by the size and number of plates in the exchanger. The heat -exchanging process is repeated in each of the plates and the collected heat is transferred to the other fluid.
Plate and Frame Heat Exchangers have proved beneficial in the food and beverage industries where they are used to maintain a safe temperature during the processing and storage of foods. In addition, they are used in chemical manufacturing to cool the various chemicals that are used in this industry.
