A degradation device in a VOC exhaust gas treatment system for automotive interior processing

Abstract

The invention discloses a degradation device in a VOC exhaust gas treatment system for automobile interior processing, which works through an electric heating plate to heat and evaporate the hydrogen peroxide solution in the lower liquid storage chamber of the evaporation tank, and the water vapor and The hydrogen peroxide vapor moves up in the lower liquid storage chamber of the evaporator and enters the mixing chamber through the one-way air inlet. At the same time, the heat in the lower liquid storage chamber of the evaporator is transferred to the upper surrounding chamber of the evaporator. The upper surrounding chamber preheats the VOC exhaust gas to make it similar to the temperature of the steam in the mixing chamber. After the upper surrounding chamber of the evaporation tank preheats the VOC exhaust gas, it enters the mixing chamber along the overflow valve to mix with water vapor and hydrogen peroxide vapor. , by setting the evaporation tank and the mixing chamber, the heat of the steam itself can be used to preheat the VOC waste gas in advance, reducing the occurrence of hydrogen oxide vapor condensing into a liquid state, reducing energy consumption, and reducing the cost of VOC waste gas degradation.

Description

technical field [0001] The invention relates to the technical field of VOC waste gas treatment, in particular to a degradation device in a VOC waste gas treatment system for automobile interior processing. Background technique [0002] In recent years, the impact of in-vehicle air quality on healthy travel has gradually become an important indicator for consumers to purchase family cars. For car companies, the improvement of car air quality has become a new competitive field in my country's auto industry. The Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the "Guidelines for Air Quality Evaluation in Passenger Cars", which stipulates that benzene, toluene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, acrolein in the air in the car concentration requirements. As an important part of the source of VOC in the car, the interior part of the car will inevitably lead to the pollutio...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a degradation device in a VOC exhaust gas treatment system for automotive interior processing, to solve the problem of the VOC exhaust gas being cooled by the cold trap in the process of mixing with hydrogen peroxide vapor and water vapor due to its relatively high temperature. Low, resulting in the gas mixing process, part of the hydrogen peroxide vapor condenses into a liquid state, and needs to be reheated to keep the hydrogen peroxide in a gaseous state. This process consumes a lot of energy, which leads to the technical problem of high cost of VOC waste gas degradation
