The coal producedduring carbonization of the high temperature waste gas, recovery and utilization of remainingheat is always one of the key technology of coking industry. Heat pipe is a high efficient heattransfer component, it has many special use and performance, it is a fast heat from one point toanother point of the device, the heat pipe components, principle of heat exchange tube heatexchanger called heat pipe heat exchanger with heat. Because of its simple structure, strongoperability, heat transfer efficiency high, small power consumption, etc., the heat pipe heatexchanger has attracted more and more attention, is heat exchange equipment with a very goodprospect. This paper to understand some physical properties of raw gas technology andrecycling of waste gas, and the development trend of heat exchanger in the discussion. Heat pipe for heat exchanger design process, mainly for the thermodynamic calculation, calculationof equipment structure, the choice of component parameter do a reasonable construction, andcombined with the actual situation of the design of the hot air preheating tube type heat transfermodel of the heat exchanger.Design in gb9948 (15CrMo) low alloy steel gravity type heat pipe,use sodium as refrigerant, fin material for low carbon steel, fin and shell for high frequencywelding. This heat pipe parameters: light pipe diameter: and; heat pipe length of 2m; heat pipediameter 0.020m; fin height: 0.015m; fin spacing: 0.0004m; fin thickness: 0.00015m; per meterlong fin number: 182. The heat pipe heat exchanger tube arrangement for the equilateraltriangle arrangement, away from the center of lateral pipe 0.065m. can will import 760 DEG Cfor raw gas down to 340 DEG C, heat transfer effect very obvious.Key Word: Waste gas; heat pipe; heat pipe heat exchanger; thermal calculation; equipmentstructure calculation
