Switching concentration type heat accumulation catalytic combustion organic waste gas treatment system

Abstract

The invention discloses a switching concentration type heat accumulation catalytic combustion organic waste gas treatment system. The switching concentration type heat accumulation catalytic combustion organic waste gas treatment system comprises a desulfurization and denitrification treatment device, a switching type concentration desorption device and a heat accumulation catalytic combustion device. An outlet of the desulfurization and denitrification treatment device is connected with an inlet of the switching type concentration desorption device, and a purification discharge port of the switching type concentration desorption device is connected with a chimney. A concentration discharge port of the switching type concentration desorption device is connected with the heat accumulation catalytic combustion device through a pipeline. A desorption inlet of a first adsorption module and a desorption inlet of a second adsorption module are connected with a desorption air inlet pipe provided with a valve. The switching concentration type heat accumulation catalytic combustion organic waste gas treatment system has the technical beneficial effects that contained organic waste gas can be effectively purified, and the energy saving effect is obvious; and VOC is completely catalyzed and degraded and does not pollute the environment any more, and the switching concentration type heat accumulation catalytic combustion organic waste gas treatment system is suitable for conducting waste gas purification on chemical plants, printing and dyeing mills, pharmaceutical factories, alcohol plants, feed plants, sewage treatment plants, garbage treatment stations, garbage power plants and other enterprises generating organic waste gas such as waste and smelly gas.

Description

【Technical field】 [0001] The invention relates to a waste gas treatment system, in particular to a switching concentration type heat storage catalytic combustion organic waste gas treatment system. 【Background technique】 [0002] The painting process is widely used in machinery, electrical equipment, home appliances, automobiles, ships, furniture and other industries. Raw materials for spray paint - coatings are composed of non-volatile and volatile components. The non-volatile components include film-forming substances and auxiliary film-forming substances, and the volatile components refer to solvents and thinners (mainly xylene). The organic gas in the paint exhaust gas comes from the volatilization of solvents and thinners. The organic solvent will not adhere to the surface of the painted object with the paint, and will be completely released during the painting and drying process to form organic waste gas. Generally, the amount of xylene waste gas volatilized in the pa...

AI Technical Summary

Problems solved by technology

The two-phase suspended matter formed after the atomization of paint and solvent in the spray painting operation escapes into the surrounding air, which will seriously pollute the air

[0003] At present, the industry mainly adopts condensation method, adsorption-vacuum desorption post-absorption method, combustion method, membrane separation and other treatment methods. The existing organic waste gas treatment methods are single, either the treatment effect is poor, or most of the energy is consumed, which increases the treatment cost.
