Description

technical field

[0001] The invention relates to a plate type air preheater used for heat exchange between high-temperature flue gas of boilers, heating furnaces and waste gas catalytic incinerators and cold air used for combustion for waste heat recovery. Background technique

[0002] At present, heat exchange equipment using corrugated plates as heat transfer elements represents the mainstream development direction of heat exchange equipment, and more and more tube heat exchange equipment has been or will be replaced by plate heat exchange equipment.

[0003] Most of the air preheaters in the prior art are heat pipe, shell and tube, heat storage and plate-fin air preheaters, which generally have low heat transfer efficiency, air leakage, large volume, easy dust accumulation and high long-term operating costs. shortcoming. Moreover, most of the existing air preheaters using corrugated plates as heat transfer elements are staggered channels, which have low heat transfer effi...
