VOC catalytic combustion exhaust gas treatment equipment

Working principle:
Firstly, the organic waste gas is filtered by a dry filter to remove some dust particles. Then, the organic waste gas that meets the adsorption conditions is sent to an activated carbon adsorption box for adsorption and purification. The purified clean gas is discharged into the atmosphere by the main exhaust fan. The adsorption equipment is equipped with one set of spare adsorption boxes. When the activated carbon is fully adsorbed, it can be switched to the catalytic incineration desorption state by controlling the valve. The desorption regeneration system can choose online desorption regeneration or offline desorption regeneration, that is, the adsorption process is a continuous treatment process. When the spare adsorption equipment is put into use, the full adsorption box will be used for desorption operation. After desorption, the activated carbon box is preheated to the next cycle for use.

Honeycomb activated carbon adsorption concentration catalytic incineration regeneration equipment in operation
Process schematic diagram of honeycomb activated carbon adsorption concentration catalytic incineration regeneration equipment
The honeycomb shaped activated carbon adsorption concentration catalytic oxidation regeneration equipment is suitable for treating organic waste gases that are at room temperature, with strong winds, low to medium concentrations, and are volatile. It can handle various types of organic solvents, including benzene, ketones, esters, aldehydes, ethers, alkanes, and their mixtures. By using a combination of adsorption concentration and catalytic incineration process, the entire system has completed a closed cycle purification and desorption process. Compared with organic waste gas purification equipment for recycling, it does not require additional power such as steam, nor does it require additional equipment such as cooling towers. The operation process does not cause secondary pollution, and the equipment investment and operating costs are low.
The honeycomb shaped activated carbon adsorption concentration catalytic oxidation regeneration equipment selects three combination processes of activated carbon adsorption, hot air flow desorption, and catalytic incineration to purify organic waste gas. By utilizing the characteristics of activated carbon's multiple micropores and huge surface tension, the organic solvents in the waste gas are adsorbed, and the discharged waste gas is purified as the top operating process; After the activated carbon is fully adsorbed, the organic solvents adsorbed on the activated carbon are removed by hot gas flow according to a certain concentration ratio and sent to the catalytic incineration bed as the second operation process; The high concentration organic waste gas entering the catalytic incineration bed is further heated and undergoes oxidation and differentiation under the action of the catalyst, converting into carbon dioxide and water. The heat released from the differentiation is recovered by the heat exchanger and used to heat the high concentration organic waste gas entering the catalytic incineration bed, which is the third operating process. The above three operating processes reach stable equilibrium after a certain period of operation.

The characteristics of catalytic incineration method: flameless incineration is easy to control, the incineration control temperature is relatively low (between 250~300 ℃), and the additional heat energy consumption is low. Different exhaust gas components require the selection of different catalysts and incineration processes.
It is necessary to filter and preheat the gas entering the catalytic incineration equipment to reach the ignition temperature of the catalyst (between 220-250 ℃), remove catalytic inhibitors such as dust particles and droplets, and prevent blockage of the catalytic bed and poisoning and failure of the catalyst.
Equipment features: Easy to operate, automatic control is completed during equipment operation.
Low energy consumption: The catalytic incineration chamber uses honeycomb ceramic shaped precious metal catalysts as carriers, which have low resistance and high activity. When the concentration of exhaust gas vapor reaches over 2000 ppm, it can maintain spontaneous combustion.

Safe and reliable: The equipment is equipped with a flame retardant dust removal system, explosion-proof pressure relief system, over temperature alarm system, and advanced self-control system.
2. It is inherently thermally balanced.

Organic waste gas has a high temperature and high organic content. Generally, only an electric heater needs to be installed in the catalytic incineration reactor for use during ignition. The heat generated by the purified gas is recovered through a heat exchanger, and under normal operation, thermal balance can be maintained without the need to compensate for heat. The process is shown in Figure 2
3. Adsorption catalytic incineration.
When the flow rate of organic waste gas is high, the concentration is low, the temperature is low, and catalytic incineration requires a lot of fuel, adsorption method can be used first to remove the organic waste gas
Adsorb onto the adsorbent and concentrate it, then blow it with hot air to desorb the organic waste gas into high concentration organic waste gas (which can be concentrated more than 10 times)

Then proceed with catalytic incineration.
