Description
Technical field
The utility model belongs to Coal Chemical Industry, petrochemical industry and field of fine chemical, and being related to a kind of volatility containing polyalcohol has
Equipment of the purification of alcohols with reclaiming in machine waste gas, the equipment is mainly used in organic containing polyalcohol (C1~C10 alcohols) volatility
Alcohols purification and recovery, particularly polyalcohol (C1~C10 alcohols) volatile organic waste gas for long boiling range in waste gas (VOC)
(VOC) or long boiling range polyalcohol (C1~C10 alcohols) volatile organic waste gas (VOC) and polarity organic waste or not acid reaction
Alcohols purification is with reclaiming in the mix waste gas of gas (aldehyde, ketone etc.) composition.
Background technology
In recent years, with the development of domestic economy, the demand of various chemical products is growing, increasing chemical industry enterprise
Industry is set up therewith.With the increasingly raising that the foundation of new spectra, the development of long-established enterprise and people are required life, enterprise
The environmental issue of industry becomes outstanding day by day.
The processing method of current traditional volatile organic exhaust gas (VOC) mainly has：Heat damage method, traditional burning at present or
Catalytic combustion technology is gradually replaced by heat storage type combustion (RTO) and heat accumulating type catalytic combustion (RCO) technology.But it is dense by waste gas
The influence of impurity in degree and waste gas, the application of direct combustion method is restricted, the regenerative combustion technology come into vogue in recent years
(RTO) and heat accumulating type catalytic combustion technology (RCO), operating temperature is high, and the once investment of equipment is larger, and cost is higher, works as processing
Equipment needs increase during high flux gas, can increase equipment investment.Absorption method, when having micelle or other impurities to be in waste gas, is adsorbed
Agent is easily poisoned, and absorption method is mainly used in low concentration, high-throughout VOC processing.Absorption process, pollutant is handled according to absorbent
Method is divided into chemical absorbing and Physical Absorption, and the advantage of absorption process is that absorbent can be reused, and pollutant can obtain comprehensive profit
With.Several processing methods except more than, with technology development in recent years, lower temperature plasma technology, biologic treating technique is not
Disconnected development, is constantly widened using scope.
With coal gas, the development of coal liquifaction at home in recent years, there is intermediate products first in gas processed and oil-producing technique
Side reaction is had in the synthesis technique of alcohol, synthesising gas systeming carbinol technical process to occur to produce a large amount of accessory substances, is being produced and is being refined
During can produce the substantial amounts of organic exhaust gas containing polyalcohol (C1~C10 alcohols), traditional handicraft is mostly direct by this waste gas
Emptying enters the burning of torch pipe network, and directly emptying can cause the pollution of air, and enter dropping a hint for torch pipe network, compare
Easily reach explosion limit and produce explosion danger.Meanwhile, it is vented and burns the waste for causing large-tonnage product.In fine chemistry industry
Also alcohols, aldehydes or ketone often are used as solvent, above-mentioned solvent, which is evaporate into air, easily causes volatile organic waste gas (VOC)
Pollution.At present, the purification of traditional organic exhaust gas (VOC) mainly uses thermal accumulating incinerator (RTO) or absorbing process, though
Right RTO stoves can effectively handle the organic exhaust gas (VOC) in waste gas, but equipment investment cost is higher, and in order to
Ensure the waste gas that the stable accumulation of heat of ceramic heat-storing physical efficiency then needs upstream to have steady and continuous.Waste gas is noted also before burning simultaneously
The explosion limit of interior each material, if having material in waste gas in the range of explosion limit, it is necessary to dilute waste gas using large quantity of air,
The explosion limit of waste gas is reduced, undoubtedly this will increase waste gas treatment equipment size, add the cost of exhaust-gas treatment.It is simultaneously a large amount of
Utility is burned to cause the wasting of resources.And use absorbing process to produce substantial amounts of solid waste per annual meeting, cause at waste gas
The secondary pollution of reason.
