Organic waste gas purification equipment (adsorption + catalytic combustion)
Organic waste gas purification device (adsorption and catalytic combustion) processing method is a combination of adsorption and catalytic combustion method, give full play to the advantages of high purification efficiency, their disadvantages are available for conversion, adsorbate regeneration processing makes use of its catalytic combustion heat of adsorption desorption and recovery the activity, save two energy, so as to compensate the catalyst price. For the purification of organic waste gas, this is an advanced treatment method at present.
Application range of organic waste gas treatment equipment (adsorption + condensation)
Organic waste gas purification device for organic waste gas purification treatment in normal temperature, large volume, low concentration, organic solvent can be processed including benzene, ketones, esters, alcohols, ethers, aldehydes, alkanes and their mixture.
The device can be widely used in automobile, shipbuilding, motorcycles, bicycles, household appliances, piano, container factory, painting, painting workshop organic waste gas purification, can also be used with shoe glue, tin pot, chemical plastics, printing ink, cable, enameled wire production line supporting the use of.
Working principle
The process of organic waste gas treatment can be divided into three stages:
1, using activated carbon adsorption device to fully absorb the organic components in the exhaust gas, when adsorption to a certain degree of saturation, that is, stop adsorption.
At the beginning of the 2 and second stages, an additional heater is used to heat a stream of air, and the hot gas stream is used to heat the saturated activated carbon. The adsorbed organic component is activated and gasified to escape from the activated carbon. Activated carbon that is a gaseous molecule that can re adsorb organic components;
Heat 3, organic components of removal of attached out of the gas, so as to achieve the required catalytic combustion temperature into the catalytic combustion bed, said here is essentially oxidation combustion, fast and furious under the action of a catalyst, the oxidation of organic molecules of hydrogen and carbon components into CO2 and H2O, and then through the desorption of the wind machine, into the adsorbent bed, the molecular organic components until the desorbed were oxidized, the desorption process will be completed.
Because of the considerable amount of heat released in the oxidation process, a heat exchanger is arranged in the device to heat the organic gas which is taken off and finally replace the heater.
Technical characteristics
The organic waste gas purification device adopts fully automatic control. It is easy to operate and saves energy and labor;
No flame oxidation, high purification efficiency, safe operation, safety and high efficiency;
High catalytic activity, stable performance and low resistance;
High performance activated carbon adsorbent has large specific surface area, good absorption and desorption performance, low wind resistance.
Process route selection
The choice of technological process should be based on the analysis of the process, equipment, emission characteristics, flow rate, composition, temperature, pressure and the nature of pollution. The catalytic combustion process can be divided into conventional catalytic combustion process and regenerative catalytic combustion process according to the different heating modes of the exhaust gas
