An energy-saving organic waste gas treatment system

Abstract

The invention discloses an energy-saving organic waste gas treatment system. The energy-saving organic waste gas treatment system comprises a waste gas exhaust pipe, a concentration device and a combustion-decomposition furnace, wherein the waste gas exhaust pipe is connected with a gas inlet port of the concentration device through a pipeline, a gas outlet port of the concentration device is connected with air inlet ports of two heat-accumulating type heat exchangers on the combustion-decomposition furnace respectively through pipelines, air exhaust ports of the heat-accumulating type heat exchangers are connected with a smoke exhaust tube, and the smoke exhaust tube is connected with a chimney; and a waste heat utilization pipe is arranged on the chimney and connected with a gas inlet pipe of a kiln. The energy-saving organic waste gas treatment system disclosed by the invention has the following beneficial technical effects: a gas containing VOC is combusted and degraded, thus the emission standard of almost zero can be achieved; a combustion chamber is provided with at least two switchover-type heat-accumulating type heat exchangers, one heat-accumulating type heat exchanger is used for absorbing waste gas of exhaust gas, the second heat-accumulating type heat exchanger is used for heating inlet gas, the emission heat of the combustion chamber is adequately recovered and utilized, en energy-saving effect is obvious, and the VOC is completely combusted and degraded, and cannot cause pollution to environment; and an existing kiln system is convenient to reform, and implementation of the reformation is facilitated.

Description

【Technical field】 [0001] The invention relates to a waste gas treatment system, in particular to an energy-saving organic waste gas treatment system. 【Background technique】 [0002] The drying kiln can be used to heat and dry the paint and coating on the surface of the workpiece. During the high-temperature treatment of the workpiece, the volatile organic compound (VOC) gas in the workpiece is directly discharged into the environment along with the exhaust gas, which will cause serious pollution to the environment and cause physical damage to the staff and residents in the area. [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. . 【Content of invention】 [0004] The ob...
