Treatment equipment for ink printing waste gas

Abstract

The invention discloses treatment equipment for ink printing waste gas. The treatment equipment for the ink printing waste gas comprises a water washing tower, a mist removal box, an activated carbonadsorption-desorption box, a condenser and a main fan, wherein the mist removal box is located at the downstream part of the water washing tower, the activated carbon adsorption-desorption box is located at the downstream part of the mist removal box, the condenser is located at the downstream part of the mist removal box, and the main fan is located at the downstream part of the activated carbonadsorption-desorption box. When the treatment equipment for the ink printing waste gas is used, waste gas flows through the water washing tower at first, large particles and a part of the waste gas are dissolved in water, water brought in by the waste gas flowing through the water washing tower is removed through the mist removal box, and then the waste gas enters the activated carbon adsorption-desorption box, and discharged after being up to standards. By adopting the treatment equipment for the waste gas, the treatment effect of organic waste gas is good, the treatment efficiency of the organic waste gas is 95% or more than 95%, and the organic waste gas can be guaranteed to be discharge after being up to the standards; furthermore, waste liquid produced in the process is recovered andtreated in a centralized way, thereby being green and environmentally-friendly.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to waste gas treatment equipment. 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 to...

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.
