Evil material, the extremely low purifying and dedusting device of water vapour content in institute's emission.
To solve above technical problem, the present invention provides a kind of purifying and dedusting device, is filled based on original surge purifying and dedusting
Put improvement to form, the equipment is in series by multiple purifying boxs, and purifying box is hollow sealing structure, and each upper box part that purifies respectively has
One air inlet and a gas outlet, the air inlet of first purifying box are connected with exhaust piping, the air inlet of rear cabinet and preceding case
Gas outlet be connected by pipeline, form gas channel, last purifying box gas outlet is that floss hole and environment are connected；Only
Change and scavenging solution formation clarifier-tank is contained below case, one of blow vent of each purifying box connects a hollow circular isolation
Pipe, isolated tube are installed vertically on purifying box center, and extended distance scavenging solution liquid level distance is not higher than 50CM below；Multiple purifications
Position is provided with suction motor to the gas channel of case series connection rearward, makes gas flow at high speed in purifying box, order isolation tube opening
The scavenging solution liquid level at place forms surge, and purified treatment is carried out to waste gas；The clarifier-tank bottom of purifying box has dirt-discherging outlet to pass through blowdown
Pipe sewage effluent is controlled to savings cesspool, blow-off pipe by blowoff valve, can also include one group of scavenging solution delivery device.
The purifying box is divided into three kinds of structures, and the first is dust separation case, and its isolated tube enters for what is communicated with air inlet
Gas isolated tube, a spray rod perpendicular to center is also included in air inlet isolated tube, spraying on rod has more than 1 fog-spray nozzle, sprays
It is connected above leaching rod through the top of isolated tube and dust separation case with catheter；The dust separation case is former surge purifying box base
The advantages of installing water smoke device on plinth additional to form, while gathering surge purification and mist purification, both is combined into one to reduce case
Body structure, and water smoke device, in narrow isolation tube space, dust separation is better.
Second of purifying box is precision purification case, and its isolated tube is the outlet isolated tube communicated with gas outlet, and the structure is

Can there are the dispensing for throwing the control neutralization medicament of liquid control machine 18 and the dispensing of water purification at dehumidifying purifying box 10, throw hydraulic control
Machine 18 processed, by the neutralization medicament delivery in storage case 19 to dehumidifying purifying box 10, is dehumidified in purifying box 10 by woven hose 17
Scavenging solution drug concentration highest, directly spray arrives dust separation case 1 after being extracted, and is directly contacted with the waste gas of most original, can be excellent
Change neutralization.
Due to the three casing sequential series structures of the present invention, hence it is evident that visible, the dustiness of scavenging solution is most in dust separation case 1
Height, scavenging solution dustiness is relatively low in precision purification case 5, and scavenging solution is essentially clean state in the purifying box 10 that dehumidifies, therefore
The purifying box 10 that dehumidifies, which is launched, to be neutralized medicament and extracts spraying scavenging solution, has feasibility, and have higher optimization efficiency.
This purifying and dedusting device is discharged into by blowoff valve 22 via blow-off pipe 20 at the dirt-discherging outlet 16 of three bottom halves
Storage cesspool 23 in addition, in the case where handled exhaust emission degree is relatively low, controlled to reduce cost and reducing, three purifications

Exhaust gas source handled by the present invention is discharged as preferable exhaust gas source with unpowered, if exhaust gas source is forced-ventilated, installation place
When managing facility, to remove or stop exhaust gas source actively discharge power, can not such as remove or stop its work, then require to be evacuated horse
Capacity up to 8 is more than the capacity of exhaust gas source, to form the negative pressure working condition of first two purifying boxs.Do not influenceing waste gas circulation
In the case of amount, this equipment can also increase vacuum effect by reducing the air inlet of dust separation case 1.
State when Fig. 2 shows the work of Fig. 1 embodiments, in detail in this figure, represented with bullet of different sizes of different sizes
Dirt particle, with black triangular form represent the harmful substance to be neutralized, vapor is represented with circle.
When this purifying and dedusting device works, suction motor 8 is started working, and the waste gas of the air inlet of dust separation case 1 is high
Speed suction air inlet isolated tube 2, the waste gas of entrance is full of size particles dirt and harmful substance, and waste gas is inhaled into air inlet isolated tube 2
Afterwards, the water smoke first sprayed with fog-spray nozzle 4 contacts, effectively weightening, and neutralizes wherein harmful substance.The waste gas handled by water smoke,
The air channel that the tube wall of the lower section of air inlet isolated tube 2 is formed with the liquid level of dust separation pond 101 is flowed through, the air-flow of high speed makes dust separation pond
101 scavenging solution liquid level forms surge condition, produces substantial amounts of spray foam, and waste gas passes through the U-shaped surge of spray formation of foam
Qu Shi, the dirt particle and harmful substance of wherein most fully contact with the spray foam of scavenging solution, are dissolved and suction is net
Change in liquid, so as to reach the purpose of decontamination purification.
Dust separation case 1 can improve surge effect because of negative pressure state caused by pumping.
The inside treatment facilities of dust separation case 1, the pollutant especially bulky grain that can get rid of the overwhelming majority pollute
Thing, includes 90% more than PM50 bulky grains, only remaining total amount be not more than 20-30% based on little particle dirt and harmful substance
Pernicious gas residual, but simultaneously because surge working condition produces part vapor, the subsidiary waste gas discharged in breather pipe 6
In.
The second step for handling waste gas is precision purification case 5, because precision purification case 5 is closer to the position of suction motor 8,
Therefore negative pressure is higher in case, and wherein air-flow is sprung up by the four circumferential centers of outlet isolated tube 7, and the surface of precision purification pond 501 forms W
Surge region, caused surge is higher, and dust removing effects are more preferably, thin in the remaining waste gas that can not be handled dust separation case 1
Small dirt has more strength, more accurate dust separation effect.Residual dirt in remaining waste gas is after the processing of precision purification case 5
It has been substantially eliminated that, safety dumping requirement is fully achieved, but because surge working condition produces more vapor, now outlet is isolated
The tail gas of pipe 7 is substantially vapor, and directly discharge can form white cigarette, influences equipment running perception.
The tail gas with vapor and steam of outlet isolated tube 7 is evacuated motor 8 and extracted out, and by dehumidifying, isolated tube 11 is pressed into
Dehumidify in purifying box 10, the scavenging solution liquid level compression camber for the clarifier-tank 1001 that now dehumidifies, due to the distance of isolated tube 11 that dehumidifies
Scavenging solution liquid level is nearer, and the hydrone in vapor and steam directly hits scavenging solution liquid level in air-flow high-speed cruising, net
Change liquid to absorb, so as to eliminate the aqueous ingredients in circulated gases, rapid desiccation, absorb vapor and water in tail gas so as to reach
The purpose of vapour.This process also has splendid clean-up effect to the very small amount dirt that may be remained in tail gas
In the purifying box 10 that dehumidifies, it is necessary to avoid scavenging solution from forming surge effect and produce vapor again, by following several
Individual aspect is reached.Firstly, since the gas of dehumidifying purifying box 10 is evacuated the press-in of motor 8, therefore air pressure is malleation in case,
Scavenging solution is not likely to produce surge boiling, second, can expand the bore for the isolated tube 11 that dehumidifies, the now stream at airflow passes edge
Speed can be reduced, and chance is produced so as to lower surge.Under hyperbar and relatively low air-flow velocity state, dehumidifying clarifier-tank 1001
Liquid level can form wave state, both increase dehumidifying contact surface, will not produce new steam again.
, can be in dehumidifying isolated tube 11 further to increase the chance that air-flow contacts in the purifying box 10 that dehumidifies with scavenging solution
Edge additional levels ring-type removes wet pressing wind platform 1101, distance of the increase air-flow in scavenging solution surface bottom horizontal flow sheet.Reach more preferable
Effect on moisture extraction.
Dehumidifying purifying box 10 is another the dispensing for throwing the control of liquid control machine 18 neutralization medicament and water purification, and this respect can be according to reality
Production needs the dispensing type and quantity flexible modulation to medicament, and also there is the product of throwing liquid control machine 18 of plurality of specifications in market,
Being limited property does not describe for this.
The present invention is to remove water steaming effect and spray effect with the improvement formerly invented, because the present invention is with special
Air channel structure, it is impossible to indiscriminately imitate the spray assembly design of other common purifying devices, spray assembly structure of Fig. 3-5 emphasis to the present invention
It is further explained.
In general spray purifier uses the pattern of top spray, but because the spray structure of the present invention is in air inlet isolated tube
In 2 air channel, its gas flows has considerable influence to the spray effect of fog-spray nozzle 4, and in Fig. 3, upper horizontal fog-spray nozzle is with
Fog-spray nozzle does not have the space spray effect of air-flow, and the spray effect pair influenceed with the right by downdraught on the left side on direction
Than, it is seen that the fog-spray nozzle 4 on present invention spray rod 3 should be installed by the way of upward spraying.
Downdraught also affects the horizontal fan spray angle of fog-spray nozzle 4 in addition to the spray height for influenceing fog-spray nozzle 4,
Its spray angle is made to diminish, because the index is influenceed by spatial interaction in air-flow velocity, air pressure size and air inlet isolated tube 2, compared with
Seldom arrive exact value.The big wide-angle fog-spray nozzle of 150-160 degree is typically estimated as 120 degree of spray angles, 120 degree small wide-angle is sprayed
Mist head is estimated as 90 degree of spray angles, to simplify detail design program.Less than 90 degree of low-angle fog-spray nozzle is simultaneously not suitable with this hair
Bright working environment demand.
In addition, the spraying orientation of general clarifier, often requires that the total space covers water smoke, but because the present invention is to air-flow stream
Speed has higher requirements, and the fog scope of the total space can form barrier, reduces air-flow velocity, unfavorable to implementation result of the present invention,
And there is unstable fluctuation and produces failure in the blast for being likely to cause suction motor 8.Therefore, will in present invention spraying space
Ask and maintain unimpeded gas channel.
