Absorption purification device for VOC (volatile organic compounds) gas

Abstract

The invention discloses an absorption purification device for a VOC (volatile organic compounds) gas, the absorption purification device comprises a spraying tower, a transferring box body and a combustion oxidation device, wherein a circulating water pump is arranged on the lower portion of the front surface of the spraying tower, a VOC gas inlet and a flushing water inlet are formed in one sideof the spraying tower, the flushing water inlet is formed above the VOC gas inlet, and an observation window is arranged on the upper portion of the front surface of the spraying tower; the absorptionpurification device for the VOC (volatile organic compounds) gas can well receive dirt generated by spraying during the spraying operation process of VOC (volatile organic compounds), conveniently discharges the dirt generated by the spraying, and can carry out cooling and secondary filtering treatment on the sprayed VOC gas, the influence of the temperature of the VOC gas on later combustion iseffectively reduced, a ceramic heat accumulator can be well fixed and insulated, the temperature loss of the ceramic heat accumulator is effectively reduced, and the overall effect of absorbing and purifying the VOC gas is achieved.

Description

technical field [0001] The invention relates to the field of VOC gas purification, in particular to a VOC gas absorption and purification device. Background technique [0002] VOC is the English abbreviation of volatile organic compounds. Volatile organic compounds are any carbon compounds that participate in atmospheric photochemical reactions except CO, CO2, H2CO3, metal carbides, metal carbonates and ammonium carbonate. VOC gas has certain hazards Therefore, it needs to be purified before being discharged to make it into a harmless gas, so as to meet the emission standard. [0003] The existing VOC gas absorption and purification device has certain disadvantages in use. First, the VOC gas absorption and purification device is inconvenient to centrally collect and process the dirt generated by the spray tower during the purification process. , it is more troublesome to clean the spray tower in the later stage, and the VOC gas absorption and purification device has a gener...

Problems solved by technology

[0003] The existing VOC gas absorption and purification device has certain disadvantages in use. First, the VOC gas absorption and purification device is inconvenient to centrally collect and process the dirt generated by the spray tower during the purification process. , it is more troublesome to clean the spray tower in the later stage, and the VOC gas absorption and purification device has a general effect on VOC gas treatment. The interference by the temperature of VOC gas itself will affect the combustion effect. In addition, in the process of burning VOC gas , the heating speed of the ceramic regenerator is relatively slow, and the insulation effect after the ceramic regenerator is heated is relatively general, which has a certain impact on the VOC gas purification process to a certain extent.
