High-efficiency energy-saving activated carbon fiber organic waste gas recycling system

Abstract

The invention disclose a high-efficient energy saving type activated carbon fiber organic exhaust gas recovery system, comprising at least two active charcoal adsorbers, an adsorption filter element arranged inside the active charcoal adsorbers, a valve provided with an embedded type valve core for the adsorption filter element; the valve comprises a flange, a sealing pad and an unsealing air cylinder; the flange is fixed above the adsorption filter element; the sealing pad as the valve core is arranged in a cavity which is composed of the flange and the adsorption filter element; the unsealing air cylinder is fixed above the sealing pad and is connected with the sealing pad by a connecting rod; the size of the sealing pad is adapted with the caliber of the flange. The sealing pad is arranged in the cavity which is composed of the flange and the adsorption filter element; the sealing pad is controlled by the unsealing air cylinder to seal a flange port from bottom to top; a sealing direction of the sealing pad is the same as an impact direction of the vapor in the course of the adsorption; therefore, the higher a vapor pressure is, the better the sealing effectiveness is.

Description

technical field [0001] The invention relates to an organic waste gas treatment and recovery system. Background technique [0002] With the rapid development of the national economy, the consumption of aromatic solvents such as benzene, toluene and xylene, as well as solvents such as alcohols, esters and acetone in the printing industry, spraying, packaging, tanning, shoemaking and other industrial fields has increased sharply. Most of these VOCs are toxic. A considerable part of them is finally discharged into the atmosphere in the form of organic waste gas, causing serious air pollution, which in turn destroys the environment on which human beings live, endangers people's lives and health, and hinders social and economic development. At present, people's awareness of environmental protection is constantly increasing, and the recycling of organic waste gas has attracted people's attention. Recovering organic solvents from organic waste gas emitted by industries can not only...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the disadvantages of poor sealing effect of the valve cover of the adsorber in the prior art, resulting in energy waste and poor desorption effect, and provides a high-efficiency and energy-saving active carbon fiber organic waste gas recovery system, which has a good sealing effect in the desorption process advantage
