Printing workshop biological vocs gas purification system

Abstract

The invention relates to a biological method VOCs gas purification system of printing workshops. The biological method VOCs gas purification system comprises an air conditioning unit, a pipeline system of the air conditioning unit, and runner type biological method VOCs gas purification devices composed of a biological reaction tank body, a biological carrier structure and a liquid storage tank, wherein a plurality of runner type biological method VOCs gas purification devices are connected in series and are communicated with the air conditioning unit and the pipeline system of the air conditioning unit to form the VOCs gas purification system; the biological carrier structure is a structure which is composed of biological filter plate blades (7), an external clamping ring frame (6) of the biological filter plate blades and an internal clamping cylinder (8) of the biological filter plate blades and rotates along with a wheel axle (9); outlets of an external circulating air outlet pipe (19) and an internal circulating air outlet pipe (20) of each printing workshop are respectively communicated with the air inlet pipe (1) of the corresponding runner type biological method VOCs gas purification device. An active carbon microorganism carrier layer is integrated at a high density in a narrow space, so that VOCs gases of the printing workshops can reach sufficient degradation and the national emission stand, and is suitable for a large area.

Description

technical field [0001] The invention relates to a removal and purification system of volatile organic compound (VOCs) gas, in particular to a biological VOCs gas purification system suitable for packaging and printing workshops. Background technique [0002] The tail gas or indoor space emitted by factories often contains volatile organic compounds (volatile organic compounds) that are harmful to the environment and human body, so corresponding treatment must be implemented to reduce their content. With the continuous and stable development of the national economy and the rapid development of the upstream ink industry of the printing and packaging industry, the printing and reproduction industry has developed rapidly in recent years and has become the pillar of the cultural industry. The main pollutants emitted by the printing industry are organic waste gases containing VOCs. The VOCs mainly come from the volatilization of VOCs caused by various inks, organic solvents and ad...

AI Technical Summary

Problems solved by technology

The existing bioreactors have the following deficiencies. First, the floor area is large, and the biological deodorization reaction requires a long reaction time. The waste gas needs to stay in the bioreactor for a long time to achieve a good removal effect. This will inevitably increase the footprint of the reactor

Second, the existing products are not effective in treating complex exhaust gas. The harmful components in the exhaust gas are relatively complex, some are organic and some are inorganic, and there are many kinds of organic components. To remove harmful components in the exhaust gas, it is necessary to cultivate harmful components Play a better role in removing microorganisms and provide it with a good growth environment

[0008] Although this patent has the advantages of wide adaptability, small footprint, simple structure, and simple operation, it still has the defects of insufficient processing efficiency and insufficient purification effect for the treatment of VOCs gas in high-concentration and large-area printing workshops.

It cannot meet the requirements of VOCs gas purification in the packaging and printing industry

Moreover, the device can only be operated with one click, and it is basically powerless to deal with VOCs gas in large-area printing workshops, and it is difficult to deal with it
