VOCs (volatile organic compounds) waste gas treatment combination device

Abstract

The invention relates to a VOCs (volatile organic compounds) waste gas treatment combination device and belongs to the technical field of air purification. A filter, an adsorption fan and a treatment zone of a concentration runner are connected sequentially through pipelines, gas is filtered, adsorbed, purified and released to the atmosphere, an output end of the adsorption fan is connected with a cooling zone, a heating pipeline of a second heat exchanger, a regeneration zone, a desorption fan, a heating pipeline of a first heat exchanger and an input end of a combustion device are connected sequentially through pipelines, an output end of the combustion device, a cooling pipeline of the first heat exchanger and a cooling pipeline of the second heat exchanger are sequentially connected, the concentration runner is driven by a motor to rotate, the filter comprises an upper chamber and a lower chamber, four filtering cavities are formed in the upper chamber from an inlet to an outlet sequentially, and coil pipes and water baffles are arranged in the filtering cavities respectively. The early filtration effect of the device is better, the conditions that other pollutants react with VOCs and impurities are decomposed and generate other pollutants when heated are prevented, and the waste gas treatment effect is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of air purification, and relates to waste gas treatment equipment, in particular to a VOCs waste gas treatment combined device. Background technique [0002] In my country, VOCs (volatile organic compounds) refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or those with corresponding volatility at 20°C with a vapor pressure greater than or equal to 10Pa. All organic compounds can be further divided into alkanes, aromatics, esters, aldehydes and other categories, and more than 300 types have been identified so far. When the concentration of volatile organic compounds in the indoor air is too high, it is easy to cause acute poisoning, and it may be life-threatening. The probability of deformity is much higher than that of ordinary people, and it may affect the child's future intellectual development. At the sam...

When the concentration of volatile organic compounds in the indoor air is too high, it is easy to cause acute poisoning, and it may be life-threatening. The probability of deformity is much higher than that of ordinary people, and it may affect the child's future intellectual development. At the same time, the volatile organic compounds in the indoor air are also important causes of children's nervous system, blood system, and children's acquired diseases.

[0003] VOCs exhaust gas treatment is of great significance to human health. At present, there are systems for VOCs exhaust gas treatment. However, due to the presence of other pollutants and impurities in the air, when VOCs exhaust gas is treated, poor filtration in the early stage often occurs, resulting in VOCs in the later stage. Additional reactions occur during treatment to produce new pollutants, and impurities are burned and decomposed into new pollutants. The final waste gas treatment effect is poor.
