Description
Technical field
The utility model relates to technical field of chemical, specifically a kind of chemical emission cyclic processing device.
Background technology
The various organic compound from waste gas such as hydrocarbon, alcohol, aldehyde, ketone, ether, ester, amine carboxylic acid, aromatic hydrocarbon, phenols in the waste gas that the industries such as petrochemical industry are discharged, harmful, the common symptoms caused is fatigue and weak, dizziness headache, n and V, nervous asthma, blood change etc.The material such as aldehyde, amine also foul smelling.Organic exhaust gas can also cause photochemical fog, causes secondary pollution.The purifying treatment method of current organic exhaust gas mainly contains absorption method: utilize the surface force of adsorbent organic exhaust gas adsorption at adsorbent surface, to purify the waste gas of discharging in production process.The molecular weight of waste gas is larger, and boiling point is higher, and concentration is higher, and temperature is lower, then the adsorption capacity of adsorbent is larger, and adsorption cycle is longer.Absorption method is applicable to the purification of low-concentration organic exhaust gas, also can be used for high-concentration organic waste gas and reclaims.Conventional adsorbent has active carbon, silica gel, ion exchange resin etc.But cost is higher, application is less at present.Burning facture-organic exhaust gas, under the effect of temperature 200 ~ 400 DEG C with catalyst, is oxidized to carbon dioxide and water, releases the combustion heat simultaneously.Production by Catalytic Combustion Process is mainly used in the purification of organic exhaust gas of high temperature, high concentration, continuous blow-down, and under temperature is 600 ~ 800 DEG C and the holdup time is the condition of 0.3 ~ 0.5 second, organic gas can burn completely, becomes carbon dioxide and water.Direct combustion method is applicable to the organic waste-gas purification of high temperature, high concentration, and heat-recoverable.It is more that direct combustion method consumes the energy, should adopt heavy oil, natural gas makes pre-heat energy.During preheating, burning indoor temperature should be homogeneous, makes whole waste gas all be heated to predetermined temperature, otherwise can produce cacodorous intermediate product.If any the boiler of air volumematching, waste gas can be burnt in the boiler as air inducing.Absorption process: the method absorbing high-concentration organic waste gas with absorbing liquid.Absorbing liquid can simultaneous oxidation, neutralization part foul gas.Usual absorption process, as the pretreatment of organic exhaust gas, as dedusting, oil mist removing, except water soluble ingredient etc., and then to purify with additive method further.
But general petrochemical enterprise, due to its exhaust gas constituents complexity, is difficult to it to purify completely by a kind of method, causes in the tail gas of discharge and also contain gas harmful in a large number, have a strong impact on the healthy of nearby residents.
