Ink printing waste gas treatment system

Abstract

The invention discloses an ink printing waste gas treatment system, which comprises a water washing tower, a demisting box, an active carbon adsorption and desorption box, a condenser and a main fan,wherein the demisting box is positioned at the down stream of the water washing tower; the active carbon adsorption and desorption box is positioned at the down stream of the demisting box; the condenser is positioned at the down stream of the demisting box; the main fan is positioned at the down stream of the active carbon adsorption and desorption box. By using the system, waste gas firstly passes through the water washing tower; big particles and partial waste gas are dissolved in water; then, moisture brought since the waste gas flows through the water washing tower is removed through thedemisting box; next, the waste gas enters the active carbon adsorption and desorption box and is then discharged in a standard reaching way. By using the waste gas treatment system, the treatment effect on the organic waste gas is good; the treatment efficiency of the organic waste gas is greater than 95 percent; the standard reaching discharge of the organic waste gas can be ensured; the waste liquid generated in the process is integrally recovered and treated; green and environment-friendly effects are achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a waste gas treatment system. Background technique [0002] Industrial waste gas usually contains pollutants such as waste gas and dust, which are usually harmful to human health and the environment. For example, these pollutants enter the human body through breathing, skin contact and digestive tract, which will cause endocrine dysfunction and affect the human immune function, cardiovascular and central nervous system. Therefore, the issue of waste gas treatment has received great attention. [0003] The current ink printing waste gas treatment efficiency is low, the effect is not obvious enough, and the treatment process is relatively simple. Most of them use activated carbon to absorb and then discharge directly. In many cases, they cannot meet the emission standards; Water washing towers are often used. [0004] Among them, the water washing tower is compos...

AI Technical Summary

Problems solved by technology

Although water washing efficiency can be improved to a certain extent and energy is saved, devices such as spoilers, counterflow paddles and their motors directly lead to high equipment costs, and poor demisting effects, which affect the requirements of waste gas treatment standards or the next process.
