Container-type low-concentration organic waste gas purification treatment device

Abstract

The invention discloses a container-type low-concentration organic waste gas purification treatment device which comprises a framework with the boundary dimension equal to that of a standard container. The framework is vertically arranged and internally provided with a first biological membrane drip filter area, a second biological membrane drip filter area, a demisting and adsorbing area, a spray liquid circulation water tank and the like. A gas inlet is formed in the lower portion of the first biological membrane drip filter area, and the top of the first biological membrane drip filter area is communicated with the lower portion of the second biological membrane drip filter area through a first gas delivery channel. A demisting unit and an adsorbing unit are sequentially arranged in the demisting and adsorbing area from bottom to top. The top of the second biological membrane drip filter area is communicated with the lower portion of the demisting and adsorbing area through a second gas delivery channel, the top of the demisting and adsorbing area is communicated with a third gas delivery channel, and an exhaust port is formed in the third gas delivery channel. The waste gas purification treatment device is arranged in the container framework and has the advantages of being compact in structure, small in occupied area, not prone to leakage, low in energy consumption and manufacturing cost, convenient to transport, install and debug and the like.

Description

technical field [0001] The invention relates to a waste gas treatment device, in particular to a container-type low-concentration organic waste gas (VOC) purification treatment device, especially a waste gas purification treatment device integrating a biofilm trickling filter tower, activated carbon adsorption and related gas channels. Background technique [0002] Low-concentration organic waste gas is often produced during the production process, such as spraying, discarded plastic regeneration modification granulation, injection molding, etc. The waste gas needs to be purified and treated to meet the standard before it can be discharged. A lot of research and practice have proved that biofilm trickling filter tower and activated carbon adsorption have remarkable effects on the purification of these low-concentration organic waste gases, and are mature processes. It is generally composed of spray tower, demister tower, adsorption tower, spray liquid circulation pool, etc. ...

AI Technical Summary

Problems solved by technology

Its disadvantages lie in: 1. Each processing unit is arranged in a scattered manner, which occupies a large area and has many equipment bases; the cost is high

2. There are many pipe connections, which are prone to leakage

3. The gas flow is long and the resistance is large, which requires a large fan power and high energy consumption

4. The transportation of the equipment is inconvenient, and the installation and debugging are difficult
