  Regenerative catalytic combustion equipment is a typical gas & mdash; Solid phase catalytic reaction and combustion method are divided into direct combustion method and catalytic combustion method
Direct combustion refers to the direct decomposition of high concentration organic waste gas into non toxic substances at high temperature with fuel or gas as auxiliary data
Catalytic combustion method means that in the catalytic combustion equipment, the organic waste gas is preheated first, and then through the action of the catalytic bed, the complete set of regenerative catalytic combustion equipment includes: 1
Waste gas washing tower: the waste gas washing tower is generally a vertical spray washing packing tower, and the internal nozzle and filling layer are distributed alternately
The filler has a large specific surface area, which is used to increase the contact area between the two fluids
The waste gas enters from the bottom, passes through the packing layer and demister, and is discharged from the top
The liquid is pumped to the nozzle, ejected, dropped down, and returned to the water tank through the packing layer
The impurities in the waste gas adhere to the filler and then enter the water tank under the action of water flow to achieve the purpose of interception
The impurities in the water tank shall be cleaned regularly, and the sewage shall be discharged regularly
2、 Photolysis catalytic combustion equipment: decompose the polluted gas into harmless and odorless gas through destruction, decomposition and catalytic oxidation
C-band light strongly cracks the molecular chain of polluting gas, changes the molecular structure of substances, and splits and oxidizes macromolecular pollutants into low molecular harmless substances, such as water and carbon dioxide
Generally speaking, photocatalytic oxidation is the catalytic action under the action of External visible light
Photocatalytic oxidation reaction uses semiconductor and air as catalyst and light as energy to degrade organic matter into CO2, H2O and other harmless components
3、 The pretreatment system of catalytic combustion treatment process usually selects pre processor, water curtain purifier, spray purifier, dust collector, dust collector and other supporting purification equipment and accessories
In organic waste gas treatment, there are usually mixtures of particles, paint mist, heavy metals, halogen compounds and so on
Therefore, these mixtures should be strictly purified before organic waste gas purification
4、 Catalytic combustion bed: it is composed of electric heating chamber, catalytic chamber, heat exchanger, flame arrester, temperature detector, electric valve and thermal insulation pipeline
The electric heater is used to heat the waste gas generated by the production line, so that the organic waste gas can be converted into CO2 and H2O at about 280 ℃ - 300 ℃ under the action of catalyst, and release a lot of heat, and then reuse the heat through the heat exchanger
5、 Control system: it is composed of PLC electric control cabinet, temperature display instrument, electric valve actuator and panel simulation flow chart
Characteristics of regenerative catalytic combustion equipment: 1
High treatment efficiency
The purification rate of organic waste gas treated by catalytic combustion method is excellent
In addition, due to low temperature, it can greatly reduce the generation of NOx
2、 Compared with direct combustion, catalytic combustion of organic waste gas has the remarkable characteristics of low ignition temperature and low energy consumption
In some cases, external heating is not required after the ignition temperature is reached
3、 Wide application range catalytic combustion can treat almost all hydrocarbon organic waste gases and odor gases, that is, it is suitable for the treatment of various organic waste gases with wide concentration range and complex components
For the waste gas with low concentration, multi-component and no recovery value discharged by organic chemical industry, coating, insulating materials and other industries, the treatment effect of adsorption catalytic combustion method is good
