Dehydration is established the spinning liquid dehydrator in the clean room, and the spinning liquid sheet base of this eddy flow dehydrator and axial inclination are greater than 25 ° and less than 45 °.
In addition, tubular type impulse device, eddy flow dehydrator, overflow pipe, mozzle can adopt pottery, cast iron or acid-resistant stainless steel material to make.
Alembic of the present invention has following advantage, the purification efficiency height of single device (efficiency of dust collection is greater than 98.5%, and pernicious gas is removed rate greater than 95%); Equipment resistance loss little (800-1000Pa).Simultaneously, the machine utilization controllability is big, and load all can keep the stable high efficiency and the performance of lower resistance between 50-130%.Operation consumption liquid (water or absorption liquid) amount is few, and the Purge gas moisture content is low, waste water recycling capable of circulation.This equipment is finalized the design, standardization, simple installation, operation, convenient management, long service life.
Accompanying drawing is a structural representation of the present invention.
Below in conjunction with drawings and Examples the present invention is described in further detail:
A kind of bubbling-type multi-tube liquid film flushing cleaner, comprise shell 1, be arranged on the gas outlet 2 of shell upper end, be disposed with dehydration clean room 3 in the enclosure from top to bottom, bring into gas port 4 plenum chamber 5, hold adsorption liquid intensify dust trapping chamber 6, the latter half that intensifies dust trapping chamber is the flue-dust retainer 8 of band ash hole 7, the dehydration clean room is provided with mozzle 9 with intensifying between the dust trapping chamber, the bottom, clean room of dewatering is provided with overflow pipe 10 and stretches in the liquid level that intensifies dust trapping chamber.The plenum chamber bottom is provided with stretches into the tubular type impulse device 11 that intensifies dust trapping chamber, the lower end indentation of tubular type impulse device, negotiable gas; Also be provided with on the shell and intensify that dust trapping chamber is communicated with, as can to regulate the liquid level that intensifies dust trapping chamber water level regulating box 12.The top of tubular type impulse device is provided with and makes tubular type impulse device inwall be furnished with the liquid distributor 13 of evenly dirty adsorption liquid.Dehydration is established spinning liquid dehydrator 14 in the clean room, and the spinning liquid sheet base of this eddy flow dehydrator and axial inclination are greater than 25 ° and less than 45 °.
After waste gas enters plenum chamber 5 by air inlet 4, air velocity reduces bigger, be full of full chamber and enter in a plurality of tubular type impulse devices 11 of correspondence layout air-flow acceleration operation vertically downward, and dirty absorption (reaction) liquid film on the tube wall that contacts, rubs with even component and VELOCITY DISTRIBUTION.Grit in the air-flow and harmful gas component are wetting by adsorption liquid (reactant liquor), absorption, or mixed haptoreaction; Under the acceleration of gravity effect of operation downward vertically, be adsorbed to fling in the catch liquid and be captured with wetting grit, intensify liquid level simultaneously and cause the adsorption liquid atomizing, continue to mix contacting the tiny grit of capture with air-flow.The vertical air-flow that dashes down in the tubular type impulse device 11, because of the water conservancy diversion part of tubular type impulse device pours under the liquid level of adsorption liquid, part is laterally evenly passed by the shallow pressure split channel of tubular type impulse device.The gas that pours under the liquid produces the bubbling effect, absorption liquid absorption grit wherein, and the bubbling effect impels the absorption liquid atomizing again, and abundant and shallow pressure is shunted, and the air-flow that laterally passes is fully mixed to be contacted.Because said flow is gone out, effects such as bubbling intensifies, bubbling intensifies in the space of capture (reaction) chamber 6, be full of the droplet of absorption (reaction) liquid, and the air-flow of reduction of speed behind the impulse, interval equably, contact with absorption (reaction) liquid of droplet shape fully and then continue wetting-assembly-collision-seizure grit with fixed attention intensifying separately, by the gravity effect in the flue-dust retainer 8 that sinks.In said process, gas contacts repeatedly with absorption (reaction) liquid, mixes, and is that the even contact of a plurality of components is mixed, and its gas-liquid mixed is abundant, and contact (reaction) time is long, its purification for this reason (dedusting, desulfurization, cigarette etc. deoils) efficient height.
Intensify 6 spaces, capture (reaction) chamber at bubbling and separate the air-flow of removing dirt and liquid grain, introduce dehydration clean room 3 by mozzle 9 through the gravitational settling effect.Enter in the dewatering station, the air-flow reduction of speed spinning liquid dehydrator 14 that evenly leads, carry out the solution-air centrifugation with higher swirl velocity and short centrifugal moment, the liquid grain that is separated, throwing to the bigger wet wall of area adheres to, flow in the overflow pipe along under the wall, introduce in the flue-dust retainer 8, discharge by gas outlet, top 2 through taking off the liquid purified gas.The characteristics of spinning liquid dehydrator of the present invention are: (1) spinning liquid sheet base and axial inclination are little, and its inclination angle is 25 °-45 °.Adopt the advantage of axial small inclination to be, both shortened centrifugal moment, what increased again that the liquid grain separates catches (adhesion) area.Promptly under the effect that equates centrifugal power, centrifugal moment is short, and then the liquid grain of its centrifugal small particle diameter of dishing out is many, then solution-air separative efficiency height; And wall is bigger with the contact-making surface of the liquid grain of being dished out, then its adsorption liquid grain amount just the more, on the contrary, the liquid grain amount in its reflection shot return-air stream is just more lacked.Because above-mentioned two effects, therefore axially the dewatering efficiency of small inclination spinning liquid dehydrator has solved the difficult problem of clarifier band water than common eddy flow plate hight.
Grit in the flue-dust retainer 8 is deposited on the bottom, carries out continuously or the interstitial row mortar, and the mortar of discharge can carry out filtrate with filter bag, convenient concentrated transportation.Water level regulating box 12 is communicated with flue-dust retainer, is provided with the balance adjustment scale.During the equipment operation, according to clarifier import and outlet pressure reduction sensing equipment resistance.(during Δ P＞200Pa), then can regulate the overflow liquid level of water level regulating box, just can adapt to load variations, keep stable purification efficiency and relevant device resistance, guarantee clean-up effect when change in resistance is big by the scale data.
