Embodiment Construction

[0017] The complete set of industrial tail gas treatment equipment for carbon fiber reinforced graphite as shown in the attached figure has a falling film absorption tower 1, a packed tower 7, and a cooling tower 8, which are used for the treatment of tail gas from hydrochloric acid synthesis.

[0018] In the falling film absorption tower 1, the part in contact with the tail gas is made of full carbon fiber reinforced graphite; the inner wall of the part in contact with the solution is made of graphite or carbon fiber reinforced graphite, and the outer wall is made of stainless steel plate.

[0019] The upper part of the falling film absorption tower 1 has tail gas inlet and absorption water inlet, and the lower part of the falling film absorption tower is connected with a solution tank 3 . The place above the liquid level in the solution tank 3 has an organic gas outlet, and the place below the liquid level in the solution tank 3 is connected with a solution heating and therma...

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. [0003] Falling film absorbers made of graphite used in the production of synthetic hydrochloric acid in my country. The falling film absorption reactor is an absorption reactor in ...
