Description
Technical field
The invention belongs to handle VOCs exhaust gas field more particularly to a kind of skid module formula processing VOCs exhaust gas device and
Method.
Background technique
The prior art and defect:
VOCs (Volatile Organic Compounds, volatile organic matter) be a kind of strong volatility, it is irritant,
There are special odor, toxic organic gas, photochemical fog can be formed and destroy ozone layer, there is significant damage to environment；In addition,
VOCs can also inhibit human central nervous system, have certain carcinogenicity.Petroleum, chemical industry, automobile, printing and dyeing, electronics, metallurgy
Etc. industries can produce volatile organic matter.Existing VOCs processing technique include recovery technologies and the burnings such as condensation, absorption,
Technology is destroyed in photodissociation etc., still, single processing technique often exist processing not enough thoroughly, treatment effeciency is lower, higher cost,
Cause secondary pollution problems.
In addition, structure is complicated mostly for existing processing unit, involve great expense, it is fixedly mounted irremovable, for certain
The pollution sources that noncontinuity process, temporary device, emergency situations generate, are not able to satisfy its instant needs arrived.
Solve the difficulty and meaning of above-mentioned technical problem:
Therefore, these problems are based on, provides and a kind of takes spray pretreatment+ultraviolet catalytic+adsorption technology processing work
Skill combination, VOCs removal efficiency is suitable for all kinds of up to 95% or more after spray, ultraviolet catalytic oxidation and adsorption treatment
The VOCs exhaust gas of high-concentration and low-concentration and occasion has the advantages that the low sled of simple applied widely, Operation and Maintenance, safety, operating cost
The device and method of dress modular processing VOCs exhaust gas has important practical significance.
Summary of the invention
Present invention aims at for solve well-known technique present in technical problem and provide one kind take spray pretreatment+
The combination of ultraviolet catalytic+adsorption technology treatment process, VOCs is removed after spray, ultraviolet catalytic oxidation and adsorption treatment
Efficiency is up to 95% or more, suitable for the VOCs exhaust gas of all kinds of high-concentration and low-concentrations and occasion, with applied widely, Operation and Maintenance is simple
Easily, the device and method of the skid module formula processing VOCs exhaust gas of the low advantage of safety, operating cost.
Another object of the present invention is to provide a kind of using skid mould to solve technical problem present in well-known technique
Blockization design, facilitates vehicle-mounted transport, the setting of device subregion, and treating capacity is handled according to the skid module formula that on-site actual situations are adjusted
The device and method of VOCs exhaust gas.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that
A kind of device of skid module formula processing VOCs exhaust gas, the device of the skid module formula processing VOCs exhaust gas include
Pretreatment spray equipment, ultraviolet lamp catalytic unit, adsorbent equipment, condenser and cyclic water tank, the exhaust gas pass sequentially through pre- place
Spray equipment, ultraviolet lamp catalytic unit and adsorbent equipment are managed, is filled with many-sided ball filler, institute inside the pretreatment spray equipment
It states the medicament in cyclic water tank and is sprayed at the many-sided ball filler surface, absorption in the adsorbent equipment by pre-processing circulating pump
It is regenerated after filling adsorption saturation by high-temperature steam, the high temperature exhaust steam that the regenerative process generates is carried out by the condenser
Condensation.
Present invention process takes spray pretreatment+ultraviolet catalytic+adsorption technology treatment process combination, through spray, purple
VOCs removal efficiency is up to 95% or more after outer photochemical catalytic oxidation and adsorption treatment, suitable for all kinds of high-concentration and low-concentrations and occasion
VOCs exhaust gas, applied widely, Operation and Maintenance is simple, safety, operating cost are low.
The present invention can also use following technical scheme:
In the device of above-mentioned skid module formula processing VOCs exhaust gas, further, the exhaust gas is conveyed by blower
To pretreatment spray equipment, pretreatment spray equipment upper outlet position is provided with demister, the import of the blower with
Outlet is connect by being flexible coupling the A and B that is flexible coupling with pipeline respectively.
Demister of the invention is to remove the mist carried secretly in removing exhaust gas or droplet.
The both ends of blower of the invention, which are taken, to be flexible coupling, and vibration influences the stability of static equipment when preventing blower from working.
In the device of above-mentioned skid module formula processing VOCs exhaust gas, further, the quantity of the adsorbent equipment is
Two, it is denoted as adsorbent equipment A and adsorbent equipment B, is filled with active carbon particle and molecular sieve, regenerative process in the adsorbent equipment
The high temperature exhaust steam of generation is sent directly into sewage draining exit after being condensed by the condenser, the not solidifying component of the condenser discharge returns
The pretreatment spray equipment continues with, and the condenser is to freeze unit recirculated water as refrigerant.
The adsorbent equipment is arranged using the using and the reserved, and each equipment is fixed on the base with support, adsorbent equipment A and absorption
Device B is vertical Space Facilities, is arranged using subregion, can enable halfth area or the whole district according to tolerance difference.
In the device of above-mentioned skid module formula processing VOCs exhaust gas, further, the pretreatment spray equipment bottom

It send to left chamber or right chamber or is delivered to two chambers simultaneously, be discharged after being adsorbed through adsorbent material from middle chamber.
7. a kind of method of skid module formula processing VOCs exhaust gas, it is characterised in that: the skid module formula handles VOCs exhaust gas
Method used the device of skid module formula described in any one of claims 1-6 processing VOCs exhaust gas, the skid module
The method that formula handles VOCs exhaust gas is further comprising the steps of:
Step 1: the exhaust gas containing VOCs is pumped by blower (2) to pretreatment spray equipment (4) lower entrances through collection system, and
It is come into full contact with the chemical washing liquid sprayed downwards, removes grease particle and part volatile organic matter, preprocessed spray dress
It sets and enters ultraviolet lamp catalytic unit (7) after the dehydration of demister (6) demisting at the top of (4)；
Step 2: the exhaust gas is aoxidized in a very short period of time, is divided by the photodissociation of ultraviolet light and the catalytic action of photocatalyst
Solve contaminant molecule；
Step 3: the adsorption stuffing absorption of the adsorbent equipment is by step 2 treated excessive ozone and incompletely processed
Small molecule contaminants；
Step 4: the adsorption stuffing after adsorption saturation uses high-temperature steam desorption and regeneration, and the exhaust steam generated in regenerative process leads to
Enter condenser (11) to be condensed, condensate liquid is sent directly into sewage draining exit and is handled, and not solidifying component can return to pretreatment unit (4)
It continues with.
8. the method for skid module formula processing VOCs exhaust gas according to claim 7, it is characterised in that: the pretreatment dress
Set (4) spray temperature be 15~40 DEG C, pressure be 101~500Kpa, adsorbent equipment temperature be 15~40 DEG C, pressure be 101~
150Kpa。
9. the method for skid module formula processing VOCs exhaust gas according to claim 7, it is characterised in that: the condenser
(11) to freeze unit (10) recirculated water as refrigerant, 145 DEG C of high-temperature steam is cooled to 38 DEG C.
10. the method for skid module formula processing VOCs exhaust gas according to claim 7, it is characterised in that: pass through the step
Adsorption stuffing after rapid four desorption is dry by hot-air, humidity tester is arranged in the discharge outlet of the adsorbent equipment, when wet
When degree reaches setting numerical value, drying process terminates.
