Carbon fiber reinforced graphite industrial exhaust gas treatment complete set of equipment

Abstract

The present invention provides industrial tail gas treatment complete equipment of carbon fiber reinforced graphite. The industrial tail gas treatment complete equipment comprises a falling film absorbing tower, a filler tower and a cooling tower. According to the industrial tail gas treatment complete equipment, in the falling film absorbing tower, the position contacting the tail gas is made from the full-carbon fiber reinforced graphite, the lower portion of the falling film absorbing tower is connected with a solution tank, the position in the solution tank and with the height lower than the liquid level is connected with a solution heating and thermal cycling device, and the thermal cycling solution temperature is 50-80 DEG C; in the filler tower, the position contacting the gas is made from the full-carbon fiber reinforced graphite, the gas sequentially passes through the lower filler layer, the cooling coil pipe layer and the upper filler layer, and the purified tail gas is discharged into the atmosphere through the evacuation port; the filler in the filler tower is active carbon fibers; and in the cooling tower, the cooling temperature is less than -10 DEG C, such that most of the organic substances are subjected to liquefaction chromatography separation. According to the present invention, the tail gas treatment function is complete, the tail gas treatment is clean and complete, the useful ingredients are recovered, and the housing of the equipment has characteristics of high mechanical strength and good corrosion resistance.

Description

technical field

[0001] The invention relates to a tail gas treatment device used in the fields of hydrochloric acid synthesis and the like. Background technique

[0002] The tail gas generated in the synthesis or purification process of hydrochloric acid synthesis, sulfur dioxide, ammonia, nitrogen, etc. needs to be post-treated before being discharged into the atmosphere, usually using solution absorption, activated carbon packed tower filtration, steel or graphite cooling tower or fractional distillation tower for separation and recovery. Often the equipment does not have the combination function, the absorption, filtration or separation are not too clean and thorough, the mechanical strength of the equipment is not too high, it is easy to smooth and damage, and the maintenance cost is high.
