Description
Technical field
The utility model belongs to industrial harmful exhaust control device technical field, in particular to a kind of exhaust gas spray is washed
Wash device.
Background technique
Exhaust gas spray washing device at present is largely that air-flow only limits from bottom to up, and from top to bottom, top is set spray liquid phase
Have demister, the gas by purification rises to demisting layer, carries out condensation demisting, and final gas is discharged from exhaust outlet, gas from
Enter below demisting layer, gas is flowed along the airflow channel between adjacent coil pipe, and gas uphill process, mist, which is attached to, to be removed
On day with fog, vapor is condensed, and the more poly- the mist for being attached to demister the bigger, and when mist gravity is greater than adhesive force, mist is from disk
It is separated on pipe, but increasing demister causes pipeline to increase, increases the running resistance of whole system, pipeline easy to form is stifled
Plug increases maintenance cost etc..
Find that conventional approach has many insufficient places during practical, by explore for a long time this patent it
In can be evaded as far as possible.
Utility model content
(1) the technical issues of solving
In view of the deficiencies of the prior art, there is provided a kind of exhaust gas sprays to wash for the technical issues of the utility model will solve
Device is washed, the spray washing device, the pernicious gas that density can be made small can obtain more residence times in tower, processing
It obtains more thorough.Duct length is reduced, reduces cost, water separator easy to maintain can replace traditional in certain fields
Demister, while can also realize that solid separates, avoid the difficult situation that demister is frequently occluded.Meeting and discussing can be two-way up and down
Installation forms the pattern attacked from both sides to harmful substance in exhaust gas, greatly increases efficiency, reduces cost, reduces equipment volume.
(2) technical solution
A kind of exhaust gas spray washing device, including scrubbing tower cylinder, water pump and gas-liquid separation device, it is characterised in that: institute
Stating scrubbing tower cylinder includes air inlet, access hole, swirl-flow devices and the first spray head, and the gas-liquid separation device includes the second spray
Head, gas-liquid mixed layer, water tank and gas outlet are drenched, the scrubbing tower cylinder and gas-liquid separation device are fitted close by gas-guide tube to be connected
It connects, first spray head is closely connect with one end of spray tube respectively with the second spray head, the spray tube other end and water
Pump connection, the water pump are connect with water tank side bottom, and first spray head is respectively equipped with multiple with second spray head.
Preferably, the access hole is equipped with 5.
Preferably, the swirl-flow devices are equipped with multiple.
Preferably, the first spray head and the second spray head are respectively equipped with, and 2 downward upward for the second spray head 1.
Preferably, the gas-liquid mixed layer is that active carbon adds Pall ring.
Preferably, the accelerated passage designs funnel.
(3) beneficial effect
The utility model provides a kind of exhaust gas spray washing device, have it is following the utility model has the advantages that
The exhaust gas spray washing device passes through handle top under the premise of not changing prior art spray column reactive moieties structure
The demister in portion is changed to the vapor-liquid separating device of bottom, changes air-flow trend.Water separator benefit is a funnel shaped,
Area gradually becomes smaller, and gas flow rate is gradually increased, and under the action of inertia, vapour phase high speed is rushed in the water surface of bottom water case, water
Face forms a circular nest face under the action of air-flow, and gas just escapes in this nest face.Liquid and solid are then
It is merged in high-speed punching feed liquor body with liquid, entire steam-water separation terminates.
Detailed description of the invention
Fig. 1 is the utility model topology view；
In figure: 1 scrubbing tower cylinder, 2 water pumps, 3 gas-liquid separation devices, 4 air inlets, 5 access holes, 6 swirl-flow devices, 7 first
Spray head, 8 gas-guide tubes, 9 second spray heads, 10 gas-liquid mixed layers, 11 water tanks, 12 accelerated passages, 13 spray tubes, 14 gas outlets.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of exhaust gas spray washing device, including scrubbing tower
Cylinder 1, water pump 2 and gas-liquid separation device 3, it is characterised in that: the scrubbing tower cylinder 1 includes air inlet 4, access hole 5, eddy flow
Device 6 and the first spray head 7, the gas-liquid separation device 3 include the second spray head 9, gas-liquid mixed layer 10, water tank 11 and outlet
Mouthfuls 14, the scrubbing tower cylinder 1 and gas-liquid separation device 3 are closely connected by gas-guide tube 8, first spray head 7 and
Second spray head 9 is closely connect with one end of spray tube 13 respectively, and 13 other end of spray tube is connect with water pump 2, the water
Pump 2 is connect with 11 1 side bottom of water tank, and first spray head 7 is respectively equipped with multiple, the maintenance with second spray head 9
