Huizhou tannery waste gas treatment equipment catalytic combustion equipment waste gas combustion in

When the activated carbon of the adsorption unit is adsorbed to the degree of saturation, the adsorption unit is switched to the desorption unit
Additional heat is required for desorption
The heating device is set in the combustion furnace
After it is turned on, the catalyst is preheated at the same time
After the combustion furnace reaches the set temperature, the hot air is introduced into the desorption bed, and the organic waste gas is not sucked out from the activated carbon meter under the action of heating
Because the temperature will change the internal structure of activated carbon, thermocouple temperature sensors are set in the adsorption and desorption unit
When the temperature is high, the supplementary cooling air system can be adjusted in time, which can not only ensure the optimal desorption effect, but also provide a safe working environment for activated carbon
Even if the temperature sensor is abnormal, the adsorption unit is also equipped with physical fire-fighting facilities

High concentration organic waste gas enters the combustion furnace under the action of desorption fan
Under the catalysis of * platinum alloy, it is burned and decomposed into water and carbon dioxide, and the waste gas is purified
The combustion process is low-temperature, fast, flameless, and generates a lot of heat
It can be reused in the desorption process and combustion oxidation process of organic waste gas, so it can significantly reduce the energy consumption cost

When the concentration of organic waste gas is large, too much heat generated by combustion will lead to too high temperature of catalytic oxidation bed and affect the safety of the whole waste gas treatment system
Therefore, the system is equipped with cold air supplement device to introduce fresh air to reduce the reaction temperature and ensure the safety of the equipment

The catalytic combustion device has the advantages of simple structure, safety and reliability, energy and labor saving, no secondary pollution, small equipment floor area and light weight
The catalyst with honeycomb ceramic as carrier has low resistance and high activity
When the concentration of organic vapor reaches more than 2000 ppm, spontaneous combustion can be maintained
The power consumption is small
Due to the small resistance of the bed, the low-pressure fan can work, with less power consumption and low noise
The activated carbon layer adsorbing organic waste gas is desorbed and regenerated with the waste gas after catalytic combustion, and the adsorbed gas is sent to the catalytic combustion chamber for purification, with low operation cost
