Description
Technical field
The utility model relates to a kind of chemical emission processing units, especially a kind of effectively to remove in chemical emission
Pollutant component guarantees the chemical emission processing unit that exhaust emissions is up to state standards.
Background technique
Some gases containing volatile organic matter (VOCs) and stink are inevitably generated in chemical production process,
Such as: hydro carbons, benzene,toluene,xylene, phenols, ammonia, hydrogen sulfide.To avoid polluting atmosphere and environment, these gases at
Atmosphere cannot be directly discharged by dividing, it is necessary to just can be carried out discharge after harmless treatment (reaching discharge standard).Existing exhaust gas
Processing method is as follows: exhaust gas → pre-treat biological tower → level-one biological purifier → two stage biological clarifier → three-level biological cleaning
Device → negative pressure centrifugal blower → high altitude discharge tower.The method is suitable only for processing VOCs and odor concentration is not high and fluctuation of concentration not
Big exhaust gas, when VOCs and odor concentration are big and fluctuation of concentration amplitude is big, treatment effeciency and effect are difficult to ensure.
Summary of the invention
The utility model is to solve above-mentioned technical problem present in the prior art, and providing one kind can effectively remove
Pollutant component in chemical emission guarantees the chemical emission processing unit that exhaust emissions is up to state standards.
The technical solution of the utility model is: a kind of chemical emission processing unit, caustic wash tower is equipped with, with caustic wash tower
Bottom connection has air-introduced machine, and first circulation pump is connected between the bottom and top of the caustic wash tower, passes through RTO at the top of caustic wash tower
Blower connects with regenerative oxidation furnace, the outlet of regenerative oxidation furnace and washing temperature-reducing tower bottom connection, the bottom of the washing temperature-reducing tower
It is connected to second circulation pump between portion and top, washes top and the activated carbon tower bottom connection of temperature-reducing tower, the active carbon tower top
Portion is connected by booster fan with chimney bottom.
The utility model is provided with caustic wash tower, RTO combustion furnace, the washing devices such as temperature-reducing tower and activated carbon tower, can be by exhaust gas
NH is removed through alkali cleaning3And H2The nitrogenous sulfur-bearing ingredient such as S, is discharged by being flared off VOCs, then after activated carbon adsorption.Can have
Effect ground removes the pollutant component in exhaust gas, guarantees that exhaust emissions reaches the environmental protection standard of national regulation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
The chemical emission processing unit of the utility model is equipped with caustic wash tower 1 as shown in Figure 1:, the bottom connection with caustic wash tower 1
There is air-introduced machine 2, first circulation pump 3 is connected between the bottom and top of the caustic wash tower 1, the top of caustic wash tower 1 passes through RTO blower
4 connect with regenerative oxidation furnace 5, regenerative oxidation furnace 5(RTO) outlet and washing 6 bottom connection of temperature-reducing tower, wash 6 bottom of temperature-reducing tower
It is connected to second circulation pump 7 between portion and top, washes top and 8 bottom connection of activated carbon tower of temperature-reducing tower 6, activated carbon tower 8 pushes up
Portion passes through booster fan 9 and 10 bottom connection of chimney.
The course of work:
Exhaust gas introduces caustic wash tower 1 through air-introduced machine 2 after collecting by pipeline and drives through first circulation pump 3, iterative cycles alkali
It washes, removes the NH in removing exhaust gas3And H2The nitrogenous sulfur-bearing ingredient such as S enters regenerative oxidation furnace (RTO) 5 by RTO blower 4 later,
In regenerative oxidation furnace 5, the VOCs ingredient in exhaust gas resolves into free of contamination CO after full combustion2And H2O etc., contamination index
Basically reach discharge standard.To ensure still reach in pollutant concentration maximum value discharge standard, regenerative oxidation furnace 5 fires
It burns exhaust and initially enters washing temperature-reducing tower 6, it is cooling by 7 driving iterative cycles of second circulation pump, enter work using pipeline later
Property charcoal tower 8, cellular activated carbon is set in activated carbon tower 8, final security personnel's absorption can be carried out to exhaust gas, is adsorbed by activated carbon tower 8
Purified exhaust up to standard is pumped to chimney 10 by booster fan 9 and discharges.
The utility model embodiment before and after the processing in exhaust gas pollutant concentration respectively as shown in table 1, table 2.
