A temperature-controlled safe catalytic oxidation vocs treatment method

Abstract

The invention discloses a method for treating temperature-controlled and safe catalytic oxidation VOCs. The method is realized by using a temperature-controlled and safe catalytic oxidation VOCs treatment device. Heat transfer oil temperature: After the heat transfer oil heat storage completes normal operation, use the heat transfer oil thermal convection principle to achieve heat balance, or provide external power cycle heat transfer liquid or external power cycle and auxiliary heat dissipation and cooling to achieve heat balance, heat transfer oil absorbs catalytic reaction and releases The heat is absorbed by the fresh VOCs material to maintain thermal balance and self-continuous reaction, so as to achieve the purpose of energy saving and stable operation.

Description

technical field [0001] The invention relates to the field of volatile organic compounds (VOCs) treatment, in particular to a treatment device with strong heat storage capacity, precise and controllable reaction temperature, safe, reliable and efficient treatment of VOCs tail gas. Background technique [0002] Catalytic oxidation VOCs treatment technology is usually used to treat low-concentration VOCs materials. In recent years, with the upgrading of national and local environmental protection standards, VOCs emission limits have become increasingly stringent. Traditional VOCs treatment technologies such as adsorption and condensation methods cannot treat low-concentration VOCs materials with high efficiency for a long time, and this low-concentration VOCs materials are usually destroyed by catalytic oxidation VOCs treatment terminal technology, so as to meet the requirements of environmental protection indicators. [0003] When dealing with low-concentration VOCs materials ...

AI Technical Summary

Problems solved by technology

The initial reaction preparation time is long, inefficient, and has the following disadvantages:

When the VOCs material is in the explosive concentration range, it is easy to cause an explosion hazard when the surface temperature of the electric heating tube is too high, and there is a potential safety hazard;

[0006] 3) For the occasion of intermittent VOCs material intake, the current catalytic oxidation technology lacks effective heat storage methods or low heat storage efficiency (the heat storage capacity of traditional heat storage ceramics is insufficient)

In order to maintain the continuous response during intermittent air intake, the electric heater needs to be turned on normally and run at full power to maintain the temperature, which will easily cause huge energy loss;

[0007] 4) In the case of a large flow range, the VOCs gas heated by electric heating cannot effectively maintain the lowest temperature, thus affecting the processing capacity of the device and the processing efficiency of VOCs
