Nanjing high source environmental protection engineering Co., Ltd.   

Nanjing high source environmental protection engineering Co., Ltd. is located in Nanjing University of Technology - National University Science and Technology Park, is a research and development, processing, production, engineering services as one of the high-tech enterprises. The main business of the company is the development, design and manufacture of corrosion protection equipment in sulfuric acid industry, the development of wastewater treatment, water technology and equipment production, water treatment agent, metal surface treatment chemicals production and sales, etc.. Production plant is located in Jiangning Binjiang Development Zone, Nanjing City, covers an area of 21130m2, the total construction area of 11000M2, including plant 8700m2, annual processing capacity of up to 8000 tons. The company has a sound quality assurance system and strict management system, testing, testing, physical and chemical, measurement, radiographic testing and other equipment complete. "Customer first, quality first" is our quality objectives. Company's existing scientific and technical personnel more than 50, mainly by the twentieth Century eighty or ninety years of high school graduated from the researchers, mature technology, experienced. Senior engineer 12, master's degree and master's degree in 10, 10 engineers. Factory currently has more than 360 kinds of technical workers. 26 technical personnel, NDT personnel 6, quality control personnel 34 people, 21 welders. Leading products have Anodic protection of stainless steel tube and shell type acid cooler Anodic protection stainless steel tube and shell type concentrated sulfuric acid cooler is a kind of technology, mature, good corrosion resistance, long service life, high efficiency cooler, has been widely used in sulfuric acid production. Worldwide use of anode protection stainless steel tube shell type acid cooler production capacity of sulfuric acid plant accounted for 75% of total production capacity of sulfuric acid, the domestic current has more than 2000 sets of acid cooler in sulfuric acid production site use. Anode protection stainless steel concentrated sulfuric acid pipeline Cast iron pipe and a small number of inner lined fluorine plastic pipe are the most commonly used in the production of concentrated sulfuric acid in sulfuric acid production. Cast iron pipe is basically rely on wall thickness to increase the service life, and there is a large weight of pipe and flange connection points, leakage acid potential disadvantages such as; in the actual production, pipeline is damaged more to "trachoma" erosion wear and brittle cracking of the two burst damage form, extremely easy to cause safety accidents in production, increase the system unplanned stop time. Although the lining fluorine plastic pipe has excellent corrosion resistance, but in the practical application, there are some disadvantages of the negative pressure, when the pump starts or closes, the plastic is easy to peel off. The common 1Cr18Ni9Ti, 304, 304L, 316, 316L and other stainless steel with anodic protection technology, applied to the use of high temperature concentrated sulfuric acid transport pipeline. In the practical application, the corrosion protection effect is very remarkable, and the service life is more than 10 years. For the majority of manufacturers to provide a new choice. Anode protective stainless steel acid distributor The main disadvantages of the 12 /m2 are the structure of the cast iron claw, the points of the points are, the installation is complex, the weight is big, the flange connection point is much, the acid is not uniform, and the service life is short. Domestic current acid plant development is rapidder, the drying and absorption section is greater the anode protecting tube shell and tube acid cooler, anodically protected stainless steel pipes and other new technology, to create the conditions for the normal operation of the production. Anodic protection of concentrated sulfuric acid trough pipe type acid system has tube type, groove, groove tube type and so on many kinds of forms for users to choose, corrosion rate is < 0.05mm/a, acid is less than or equal to 45 / m2, effectively reduce the filling height. Large free ventilation area, no clogging, less acid foam entrainment, large operating flexibility. No spare parts and maintenance costs. High silicon stainless steel trough pipe type acid distributor The system of high silicon stainless steel acid distributor is mainly based on the grooved tube, which has excellent corrosion resistance, and can satisfy the requirements of corrosion resistance and processing technology. production characteristics 1 points more points. The acid distributor points up to 45 points /m2. 2 uniform low acid, acid mist. 3 drop acid pipe buried in the filler layer to avoid the acid foam splash. 4 the inlet of the tube is higher than the bottom of the acid tank, which is not easy to be blocked. 5 tower free ventilation section area, tower resistance is small. 6 the use of high silicon stainless steel, corrosion resistance, no need to support the anode protection, the service life of up to 10 years or more.
