CNG Processing Equipment The Purification Process
Motorcycle coating including the frame, CNG Processing Equipment fuel tank and other software and appearance of plastic parts of the spraying, the use of solvent-type coatings, air spraying method. Solvent-based coatings contain a large number of volatile substances, some also contain organic poisons such as benzene, therefore, CNG Processing Equipment spraying and finished product drying process will produce a large number of organic waste gas, it needs to be governed to achieve the national emission standards.
There are two main kinds of treatment methods of organic waste gas: One is recovery method and the other is elimination method. The recovery method is through physical method, CNG Processing Equipment using temperature, pressure selective adsorbent and selective permeation membrane to separate volatile organic compounds mainly including activated carbon adsorption, PSA, condensation method and biofilm method. The elimination method is through chemical or biochemical reactions, light, heat, catalysts and microorganisms, such as the conversion of organic matter into water and mainly including thermal oxidation, catalytic combustion, CNG Processing Equipment biological oxidation, corona, plasma decomposition, optical decomposition and so on.
Activated carbon adsorption and catalytic combustion "is the use of adsorption purification, thermal desorption and catalytic combustion of the combination of organic waste gas treatment methods." CNG Processing Equipment The basic operation is adsorption purification and desorption of regeneration-catalytic combustion of two processes.
Adsorption purification process is the pollution of the air by the exhaust fan to the adsorption bed, polluted air organic matter in the adsorbent bed adsorbed by adsorbent to the air purification, CNG Processing Equipment purified air discharged to the atmosphere that completes the air purification process.
Desorption and regeneration-catalytic combustion process is the adsorption of organic matter adsorbed by adsorbent in the adsorbent bed, the adsorbent bed can no longer be adsorbed, and the removal of regeneration. Desorption regeneration is used for the purpose of regenerating the adsorption capacity of the adsorbent by removing the adsorbent from the hot air (temperature of 1,001,110 ℃) from the catalytic bed. CNG Processing Equipment The concentration of the organic matter removed is 10,120 times times higher than that in the initial polluted air, and then the high concentration of organic matter is transported by the desorption fan to the catalytic bed for catalytic combustion. Organic matter in catalytic bed catalyst under the action, in 300 ℃ or so to convert organic matter into $literal and CO2, side to atmosphere. This high concentration of organic matter in the catalytic combustion of the heat released enough to maintain its catalytic reaction to the required temperature of 300 ℃, no need for external heat source, CNG Processing Equipment the hot air after combustion can be used for the adsorption of heat desorption, to achieve waste, waste energy utilization, saving the purpose.
The system consists of a fan, a cooling fan, a catalytic combustion bed consisting of a heating chamber, a catalytic combustion chamber and a heat exchange chamber, CNG Processing Equipment a flame arrester, a thermometer and a corresponding valve, pipe, and electrical control systems. The system is separated from the purifying system during operation, so that the adsorption purification system and the desorption regeneration-catalytic combustion system are not mutually affected. In the catalytic combustion bed, CNG Processing Equipment the precious metal catalyst was filled with a low temperature of 250 ℃, and the catalytic combustion rate reached 99%.
It consists of cooling water pipe, manual valve, pipe quick joint, hose, cooling water atomizing nozzle, etc. The system is mainly in the adsorption bed of local temperature anomalies, CNG Processing Equipment and other fault treatment methods can not be solved in the case of use, the purpose is to reduce the temperature in the adsorbent bed, to solve the possibility that the local temperature is too high to cause the activated carbon flame-retardant problem.
