Description
Technical field
This utility model relates to a kind of foam type cloud and mist dust-arrest device, belongs to Environmental-protecting dust-removing technical field.
Background technology
Current domestic wide variety of dedusting technology mainly has dry dust removal and wet dust removal.Dry dust removal, removes with cloth bag
Dirt and two kinds of technology application of electrostatic precipitation are relatively wide, and owing to all contaminated airs cannot all be sucked inlet air plenum, dust removing effects is big
Giving a discount, cause operating environment poor, Occupational Disease Hazards is big, and there is dust secondary pollution problem.Wet dust removal, mainly with spray
Dedusting and medicament dedusting are main, but the ability processing fine dusts is poor, causes efficiency of dust collection the highest.Part is currently also had to look forward to
The advanced technology of industry Introduced From Abroad, develops micron-sized dry fog dust inhibitor, and dust removing effects is obviously improved, but also has a small amount of
Dust become fish that has escape the net through the gap of cloud and mist.
Chinese patent CN204783087U discloses a kind of foam suppressing dust with dry mist machine, compared with existing wet type dust-arrest device,
Although foam dry fog dust-settling technology prevents the diffusion of dust, but due in this equipment dry fog and foam spray respectively, still deposit
Complicated in structure, cost high, it is impossible to fundamentally stop dust outwardly to spread, it is impossible to effectively suppression dust distribute wait scarce
Point.
Summary of the invention
The purpose of this utility model is to provide a kind of foam type cloud and mist dust-arrest device, thoroughly suppresses dust to produce from source,
Build a kind of simple in construction, low cost, efficient, practical dust-arrest device, be widely used in colliery, thermoelectricity, iron and steel, harbour, sandstone
The industries such as stock ground, thoroughly solve the yoke for the treatment of flour dust.
This practical purpose is achieved in that it includes water inlet pipe, air inlet pipe, cloud and mist nozzle and spray storage bin,
Being provided with Venturi tube in water inlet pipe, spray storage bin is connected with water inlet pipe inner venturi tube by control valve, and cloud and mist nozzle is respectively
Being connected with air inlet pipe and water inlet pipe, fill foaming agent in spray storage bin, in water inlet pipe, the water of high flow rate is incited somebody to action by Venturi tube
The foaming agent negative pressure of trace sucks in current and mixes with compressed air in air inlet pipe, and cloud and mist nozzle produces ultrasonic wave concussion, by water
Division is atomized into cystose cloud and mist and completes dust suppression process.
The foam type cloud and mist particle diameter continuously generated is 10 microns.
Compared with prior art, this utility model has the advantage that
1, simple in construction, low cost, efficient, practical.
After special type dust suppression foam formulations is proportionally mixed with water, ejected by the nozzle of two-fluid structure, shape
Become substantial amounts of foam cloud and mist, make whole soot region be covered by seamless foams.Dust in air by with cystose
Under the multiple effects such as cloud and mist adheres to, filters, condensation, little particle aggregation become bulky grain, settle down under gravity, from
Fundamentally prevent dust outwardly to spread, restrained effectively distributing of dust, owing to micro-bubble is more more stable than macrofoam,
Dust granules is after coming in contact with foam, and foam does not changes, and catches dirt effective；Additionally, dust granules is easy
After penetrating into micro-bubble inside, cause lather collapse, and then moistening dust, be more beneficial for being combined with cloud and mist.For PM10
Following respirable dust, capturing efficiency is up to 99%, is prevented effectively from the harm of anthraco-silicosis.Actual application display, semiclosed under
Dust suppression efficiency, more than 95%, can reach 99% under totally-enclosed, and appliance arrangement less investment, easy to operate, operating cost is low, (coal) nothing
Calorific value loses, non-secondary pollution.Foam cloud and mist dust suppression uses very little water, and is almost negligible.
2, applied widely.
It is widely used in the industries such as colliery, thermoelectricity, iron and steel, harbour, sandstone stock ground.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, water inlet pipe 2, Venturi tube 3, control valve 4, spray storage bin 5, air inlet pipe
6, cloud and mist nozzle.
Detailed description of the invention
The purpose of this utility model is achieved in that this device includes water inlet pipe 1, air inlet pipe 5, cloud and mist nozzle 6 and spray
Agent storage bin 4, is provided with Venturi tube 2 in water inlet pipe 1, spray storage bin 4 is by control valve 3 and water inlet pipe 1 inner venturi tube 2 phase
Even, cloud and mist nozzle 6 is connected with air inlet pipe 5 and water inlet pipe 1 respectively, fills foaming agent in spray storage bin 4, high stream in water inlet pipe 1
The water of speed will be mixed with compressed air in air inlet pipe 5 in the foaming agent negative pressure suction current of trace by Venturi tube 2, and cloud and mist sprays
Mouth 6 produces ultrasonic wave concussion, water splitting is atomized into cystose cloud and mist and completes dust suppression process.Control valve 3 adjusting size, is mixed with
The special liquid of a certain proportion of foam dust suppression mixes with compressed air together, produces ultrasonic wave concussion by cloud and mist nozzle 6, by moisture
Split the cystose cloud and mist being atomized into particle diameter 10 microns, be injected in above airborne dust point and form certain thickness foam cloud layer, will
Dust is enclosed in below Foam Cloud, owing to cloud and mist is that cystose, either area coverage or volume are the biggest, and is even
Continuous void-free.When dust rises through foam cloud layer with air-flow, on the one hand, the water smoke close based on size and dust
Particle encounter, cohesion, cloud and mist is combined formation micelle with dust, and micelle continues to agglomerate into bigger pelletizing, scale and quality
Constantly increase, can constantly assemble sedimentation, thus reach depositing dust and purify the purpose of air；On the other hand, by Foam Cloud in air
The dust granules of infiltration is trickled down when stockpile surface, also can infiltrate powder state material, thus suppress dust from flying in transportation.
Fundamentally prevent dust outwardly to spread, restrained effectively distributing of dust.
This device can continuously generate the thick fog of 10 microns sizes, and these thick fogs are cystoses, are interconnected into mutually
One, as cloud and mist, not only covers dirt source but also keep mixing with dust particle absorption.
The resonator of mechanical ultrasonic cloud and mist nozzle 6 has air-flow enlarging function, is connected part, the sky that will come at air-flow
Gas speed is accelerated rapidly, this powerful impulsive force, impinges upon on vibrations head, just creates high-frequency machinery sound wave.This
Powerful shock wave, has cut into the water of cystose the foam droplet of thousands of micron size, has then been taken away by high-speed air
It is the formation of cystose cloud and mist.
The efficiency key factor affecting foam cloud and mist dedusting is the structure of foam.Facts have proved for many years, micro-bubble is than big
Foam is more stable, and dust granules is after coming in contact with foam, and foam does not changes, and catches dirt effective;Additionally, powder
After dirt granule easily penetrates micro-bubble inside, cause lather collapse, and then moistening dust, be more beneficial for tying with cloud and mist
Close.
This foam cloud and mist dust-arrest device is exactly that the advantage of foam dust suppression and cloud and mist dust suppression is organically merged, increase with
It is attached rapidly after the collision probability of dust, dust and foam fog cloud contacts；Proprietary wetting agent contained in foam can be very fast
Change dust surface texture and dust is become hydrophilic from hydrophobicity, make dust quickly moistening and be captured, fundamentally stop
Dust recycling, anti-dust effect is fairly obvious.
