Organic waste gas purifying device

Abstract

The invention relates to an organic exhaust gas purifier, characterized in that: a filtering flame arrester connects to a airflow distributor, and a group of air inlets of absorption purification chamber communicates with airflow distributor in parallel via pipe and valve respectively; a gas collector inlet communicates with purifier outlet of absorption purification chambers in parallel via pipe and valve; a fan connects to gas collector outlet via pipe; a heat exchanger communicates with desorption exhaust gas outlet of absorption purification chambers in parallel via pipe and valve; a preheating chamber connects with other end of heat exchanger pipe in heat exchanger via pipe; an inlet and a outlet of catalytic chamber communicate with above preheating chamber and heat exchanger respectively; and the double end of air heater respectively communicates with outlet of heat exchanger and heat steam inlet of absorption purification chambers in parallel via pipe and valve. In the purifier, absorption process and desorption can be carried out simultaneously.

Description

Technical field [0001] The invention relates to an exhaust gas purification device, in particular to an organic exhaust gas purification device. Background technique [0002] With the wide application of non-metallic materials in the telecommunications, electronics, machinery, chemical and other industries, the organic waste gas generated in the production process has attracted more and more attention, especially the organic waste gas generated by spraying, chemical production, petroleum, medicine, etc. , The concentration is not too high (the high concentration is generally treated by incineration), and the treatment is very troublesome. In the prior art, the treatment is generally carried out in a concentrated manner, that is, it is adsorbed by an adsorbent to reach a certain degree of saturation, and then desorbed by hot air, and then sent to a catalytic chamber for catalytic reaction to become carbon dioxide and water. In the above treatment method, the general equipment is t...

AI Technical Summary

Problems solved by technology

In the above-mentioned treatment methods, the general equipment is to carry out adsorption and desorption intermittently, and cannot desorb during adsorption, and cannot adsorb during desorption.

There is also a device designed in the shape of an orange petal, which rotates under dynamic conditions to achieve continuous adsorption and desorption. This kind of device has particularly high requirements for dynamic sealing and is quite expensive, so it is not suitable for my country's national conditions.
