In the system, the four waste gas purification plants are combined to purify the waste gas in four levels, the system is suitable for treating high-concentration waste gases of places such as petrochemical plant and pharmaceutical factory, the system is both capable of partially recycling the organic waste gas and completely purifying the organic waste gas, the operation of the equipment is safe, the energy consumption is low, and the applicability is strong.
Description
Technical field:
The utility model belongs to environmental technology field, is specifically related to a kind of exhaust gas purifying treatment system.
Background technology:
At present, along with the high speed development of China's process of industrialization, problem of environmental pollution has become the thing that is related to people's livelihood state, especially to the discharging of industrial waste gas, has formulated strict Standard of Monitoring.
Enterprise is for the purified treatment of industrial waste gas, usually can adopt active carbon adsorption, firing method, low-temperature plasma method to process, but there is separately defective in said method and causes approximately, as: active carbon adsorption is applicable to Wind Volume, low concentration gas is processed, exist resistance coefficient large, Energy in use is large, the difficult support control of the saturation point of absorption, adsorption capacity is little, the problems such as operating cost height; All there are hidden danger in catalytic combustion and low-temperature plasma technique, can cause blast and fire.Simultaneously, the high-concentration organic waste gas that chemical plant, pharmaceutical factory etc. produce, there are the characteristics such as complicated component, concentration be high, inflammable, explosive, utilize traditional waste gas processing method all to be difficult to applicable, so carrying out effective purified treatment for industrial waste gas is technical staff's problem in the urgent need to address in industry.
The utility model content
The purpose of this utility model is exactly that concentration is high for the organic exhaust gas complicated component, inflammable and explosive characteristics and a kind of exhaust gas purifying treatment system of designing can be recycled organic exhaust gas, and waste gas purification is processed thoroughly, the equipment security of operation, energy consumption is low.
The utility model for the technical scheme that above-mentioned purpose adopts is:
Multistage combined exhaust gas purifying treatment system, its feature has condenser, photocatalyst purifying column, active carbon purifying tower and four purifiers of spray column, above-mentioned four purifiers are linked in sequence successively, the gas outlet end of spray column is connected with exhaust blower, and the lower end of condenser is connected with the condensate liquid returnable.
Ultraviolet lamp and photocatalyst device have been provided with in described photocatalyst purifying column.
Be provided with activated carbon adsorption bed and active carbon desorption device in described active carbon purifying tower.
Be provided with the spray atomizer that spray liquid is atomized into the diameter 1 following drop of μ m in described spray column.
The beneficial effects of the utility model are:
This waste gas cleaning system adopts the combination of four waste gas purification apparatuses, waste gas is carried out level Four to be purified, the high-concentration organic waste gas that is applicable to the places such as petrochemical plant, pharmaceutical factory is processed, can carry out partially recycled utilization to organic exhaust gas, can thoroughly purify again, the equipment security of operation, energy consumption is low.
When high-concentration organic waste gas passed through condenser, the organic solvent that is condensed into liquid in waste gas was recycled; Waste gas enters in the photocatalyst purifying column, under the effect of photocatalyst medium, the pernicious gases such as the benzene class in waste gas, ketone, aldehydes, NMHC by rapidly oxidation, be decomposed into innocuous substance; Pass through again the active carbon purifying tower, further remove not by degradable organic matter, adsorb and carry out desorption after saturated and process, the service life of prolongation active carbon; Enter at last spray column, carry out physical dissolution and cover effect, remove the part water soluble contaminants, thereby obtain clean gas.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, multistage combined exhaust gas purifying treatment system, have condenser 1, photocatalyst purifying column 2, active carbon purifying tower 3,4 four purifiers of spray column, above-mentioned purifier is linked in sequence successively, the gas vent of spray column 4 is connected with exhaust blower 5, and the lower end of condensing tower 1 is connected with condensate liquid returnable 11.
Condenser 1 is connected with the frozen water unit, when high-concentration organic waste gas when the condenser 1, the organic solvent that is condensed into liquid in waste gas liquid returnable 11 recyclings that are condensed; The temperature of frozen water unit recirculated water is set as required, purifies requirement higher, needs cooling temperature lower, and expense is also higher;
Waste gas after 1, enters in photocatalyst purifying column 2 in condensing tower, has been provided with ultraviolet lamp and photocatalyst device in photocatalyst purifying column 2; Photocatalyst device can produce a large amount of energetic ion agent active groups under the effect of ultraviolet lamp, the organic exhaust gas such as benzene homologues, ester class, alcohols are rolled into a ball with living radical wherein chemical reaction is occured, and are broken down into innocuous substance;
Photocatalyst service life is 10 years, and this process makes full use energy meets the requirement of national energy-saving environmental protection, is a kind of comparatively ideal processing method;
Waste gas is through photocatalyst purifying column 2, then enter active carbon purifying tower 3, being provided with activated carbon adsorption bed in active carbon purifying tower 3 further removes not by degradable organic matter, also be provided with the active carbon desorption device in active carbon purifying tower 3, adsorb and carry out desorption by the active carbon desorption device after saturated and process, extend the service life of active carbon; Above-mentioned active carbon desorption device adopts vapours;
Treated waste gas enters spray column 4 at last, in spray column, 4 are provided with the spray atomizer that spray liquid is atomized into the diameter 1 following drop of μ m, add the happy vegetation water of living in peace in spray liquid, the carefree right vegetation water of living in peace contains reactivity very high functional group compound and terpenoid, be atomized into the less gas molecule of diameter by spray atomizer, because diameter is little, specific area increases, increase than the table effect, has very strong activity, bump with air pollution peculiar smell molecule, and produce chemical shift in collision.The Main Function of spray column 4 is: 1, in waste gas, water miscible material may be dissolved in the effect that reaches purifying exhaust air in water; 2, a small amount of water-fast organic pollution and natural plant liquid generation chemical reaction are effectively removed; 3, have certain physics and cover effect;
High-concentration organic waste gas obtains clean gas through the level Four purified treatment, is discharged in atmospheric environment through exhaust blower 5.
Native system reclaims organic solvent in waste gas by condenser, has certain economic benefit, reclaims benefit and can offset the part operating cost, and do not produce the secondary pollution such as waste water; Native system can purify high-concentration organic waste gas thoroughly by the combination of four purifiers, and system run all right, and safe and reliable, applicability is strong.
