1. Enhanced heat transfer components and high-efficiency heat exchanger Research

     1.1 Cross Cemetery Rod Baffle tube heat exchanger

     This is a combination of Rod Baffle Heat Exchanger Tube band technology and an efficient technology enhanced heat exchangers. Rod Baffle Heat Exchanger is the Philips 70s last century to address the natural gas heat exchanger flow-induced vibration problem leveraged the development of a baffled heat exchanger grid. Characterized by strong anti-vibration, the elimination of the shell-side flow stagnation, improving the shell-side fluid velocity and temperature distribution. Chemical Machinery Factory in Guilin in South China University of Science and Technology with Professor Qian Songwen successful cooperation and enhanced heat transfer tubes for trace element spiral rod baffle heat exchanger, heat exchanger area to save nearly 60%, the effect is very remarkable. At present, the spiral rod-sik Rod Baffle Heat Exchanger in Guilin production plant has been systematic. In recent years, Guilin Chemical Machinery Plant, South China University of Technology Institute of Chemical Engineering and the State Education Commission to develop energy-efficient heat transfer and cooperation between research laboratories, will be in the same tube under the flow of heat transfer efficiency is better than spiral tube tubes for the band-for-Rod Baffle .1995 Reheater May in the design and manufacture of cross striations DN1400 Rod Baffle tube heat exchanger in a medium-sized fertilizer plants in Yunnan transform industrial operation system for people to replace the original use of the DN2400 Tubular Heat Exchanger Baffle板主, 540mZ heat transfer area to replace the original equipment 1627m, the heat transfer area, equipment to reduce the weight of the original 37.61d to 17.27d, investment in equipment to save 1 / 3. the application of enhanced heat transfer components and equipment to develop high-efficiency heat exchanger : greatly increase the number of enterprises in economic and social benefits. striated Rod Baffle tube heat exchanger the development and application of the results proved that the enhanced heat transfer components and Rod Baffle organic combinations. in improving the rate of heat transfer tube at the same time also increased the shell-side heat transfer rate. striated industrial operation proved highly efficient heat transfer tube, fluid resistance small, anti-vibration characteristics of a good performance.

     TUBE 1.2 holes the whole round draw Shan Baffle Plate Heat Exchanger

     China's existing medium-sized nitrogen fertilizer plant hydrogen compressor coolers, heat has long been inefficient and ineffective way cooler flow, fluid erosion caused by horizontal vibration of heat exchanger has been the unresolved technical issues directly affect the compression of nitrogen the efficiency of the machine. zoom round the whole tube gate slots baffled heat exchanger plant in the past two years, other schools to develop a new type of heat exchanger, heat transfer enhancement is also a new type of components and the structure of shell-Baffle portfolio optimization. is generally believed that enhanced convection heat transfer method is repeated to change the vertical pressure gradient under the flow of fluid, which in turn flow from the turn of the expansion and contraction of the segment to achieve. big child studies have proved that the same wave-type channel under flow resistance than the parallel flow channel has a higher heat transfer performance. zoom paragraph of its expansion of the effective use of contraction above the fluid used to improve adhesion of the effect of velocity; whole round hole Liuhong Baffle grid that is folded Shan flow circular plate as a whole can not pass bow-shaped mouth and wash the tube for each tube row bridge, the parameters can be mesh hole size required to determine the flow rate. newly developed high-efficiency heat exchanger to replace the nitrogen fertilizer plant in China's medium-sized Chinese-made hydrogen-nitrogen compressor one, two, three paragraphs back to the original cooler baffle ring. zoom round the whole tube gate slots baffled heat exchanger operation of the operation of industrial applications with significant results showed that the effect of enhanced heat transfer.
