New high-pressure and high-temperature circulating pump helps coal gasification technology enter a clean and efficient era
Time:2017/1/7    Source:Pearl Pump Industry    Views:
my country has abundant coal resources. Clean coal gasification technology has developed rapidly in recent years. The high-pressure inlet high-temperature gray water circulation pump is an important equipment for clean coal gasification process. The pump is also adapted to larger flow, higher inlet pressure, and multiple coal types. Sexual development.
 
Recently, the “Development of High Pressure and High Temperature Grey Water Circulating Pump for Coal Gasification Process” completed by Beijing Aerospace Propulsion Research Institute Wang Xiaodong, Yu Haili, Ding Yongqiang, Hao Xiaolin, Tian Guowen, Hou Jie, Lin Zhen, Liu Haili, Ren Yi, Deng Jing Won the second prize of Science and Technology Progress Award of China Machinery Industry Science and Technology Award. It is reported that the successful development of the pump effectively guarantees the stable operation of the coal gasification unit, and provides strong technical guarantee and support for the advancement of the industry.
 
   It is understood that due to the very special application of the pump, there are few coal gasification devices abroad, and there are fewer manufacturers that can design and produce such high temperature and high pressure wear-resistant pumps, and they are expensive, and the supply cycle of spare parts for equipment operation and maintenance is long.
 
  The project is mainly completed by Wang Xiaodong, Beijing Aerospace Propulsion Research Institute. The high-pressure inlet high-temperature gray water circulation pump designed and produced by the coal gasification unit is an innovative product that is independently designed, developed, and protected by intellectual property rights. It has been granted 3 patents.
 
"In the process of developing the pump, we solved many key technical problems such as sealing and axial force. Especially in view of the high pressure of the medium and the characteristics of solid particles, we changed the design concept of the previous flow part and adopted the guide vane diffuser. The method of the pump separates the pressure diffusion function and the pressure bearing function of the pump casing from the structural design, and the material selection of the pump casing is mainly considered from the pressure bearing point of view. Only the impeller, the vane diffuser, and the liner have higher liquid flow speeds. The relevant parts of the company are processed with wear-resistant materials, which innovatively solve the problems of structural design and material selection." Wang Xiaodong said.
 
At present, the pump has been widely used in various domestic coal chemical technology production enterprises, such as Shenhua Ningxia Coal-to-Liquid Project, Zhongtian Hechuang Ordos Coal-to-Olefin Project, Sinopec Nanjing Chemical Industry Company's Coal-to-Hydrogen Project, China Coal A total of more than 200 coal gasification projects such as the group's olefin projects have created significant economic and social benefits. The products in operation are stable and efficient, and are recognized and praised by users. The market share has a great advantage. Up to now, the accumulated contract value has reached more than 400 million yuan. The pump can also be used as a large-scale circulating pump in oil refining, PTA, and medium-pressure industrial boiler installations. The market has huge market potential and development and application prospects. broad.
