Abstract
Description
Technical field
The utility model belongs to spray wet dust collector technical field.Particularly relate to a kind of Wet-type spray wet dust collector.
Background technology
A large amount of dust can be produced in backfill for underground gob-side entry retaining of coal mine filling process, cause the dust concentration severe overweight in production environment, threaten the healthy of production safety and workman.Due to narrow space under mine and condition is special, the also existence had fires risk, under electric cleaner and sack cleaner etc. all can not be used for mine, there is dust concentration excessive problem in pack builders' skill.
How to solve the problem that in pack builders' skill, dust concentration exceeds standard, domestic and international researcher and engineers and technicians have carried out a large amount of theory and practice research, personnel to be concentrated and job site that dust concentration is high takes the every dust suppression comprising spray for dust suppression, also investigated various wet-scrubbing equipment, but due to the particularity of underground work condition, these wet-scrubbing equipments do not overcome that volume is large simultaneously, complex structure and the low problem of efficiency of dust collection, and effect is all undesirable.
Summary of the invention
The utility model is intended to the defect overcoming prior art, and object is to provide a kind of water saving, volume is little, structure is simple, the Wet-type spray wet dust collector of good dedusting effect.
For achieving the above object, the technical solution adopted in the utility model is: described Wet-type spray wet dust collector comprises airscoop shroud, inlet box, fumer, hood, lower box, scrubber tube and ash bucket.
The inlet end of inlet box is fixedly communicated with airscoop shroud, the end of inlet box is fixedly connected with fumer sidewall is closed, the upper end of fumer is fixedly communicated with the cover mouth of hood, immediately below inlet box, be provided with ash bucket, the upper end of described ash bucket is fixedly connected with the side plate corresponding to fumer with inlet box by four side plates of lower box.
The cover mouth of airscoop shroud is square, and the top board of airscoop shroud is horizontally disposed with; The top board of inlet box is the swash plate of inlet end higher than end, and the lower frame of the end of inlet box, the upper end of fumer and airscoop shroud cover mouth is positioned on same level line; Be provided with 3 ~ 50 row's spray headers in the casing of inlet box horizontal homogeneous, often arrange spray header and 2 ~ 10 spray spouts are housed, often arrange spray header and be positioned at described horizontal below.
The floor level of inlet box is arranged, and described base plate is the dividing plate between inlet box casing and lower box, and dividing plate has circular port equably, and the orifice area sum of circular port and dividing plate area ratio are 0.3 ︰ 1 ~ 0.5 ︰ 1; Scrubber tube is vertically equipped with in the aperture place of each circular port, and inlet box and lower box are communicated by scrubber tube.
The left plate bottom of lower box is provided with water level observation window, and the center of water level observation window and the vertical range of scrubber tube lower port are 50 ~ 80mm, and the lower port of scrubber tube is lower than the center of water level observation window.
Fumer is surrounded by four blocks of side plates, and the upper port place of fumer is provided with 1 ~ 5 row's washing pipe equably, often arranges washing pipe and 2 ~ 10 Washing spray nozzles are housed; The lower port place of fumer is provided with airflow uniform distribution plate, between Washing spray nozzle and air-flow uniform board, be provided with demister.
Described airflow uniform distribution plate is made up of framework and " V " font strip board of falling, " V " font strip board of falling is fixed on the inwall of framework equably, the width of " V " font strip board is 20 ~ 80mm, and the distance of " V " font strip board centreline space is 1.5 ~ 2.5 times of " V " font strip board width.
Described scrubber tube is conical tube, and the length of conical tube is 65 ~ 80% of lower box height, and the upper port internal diameter of conical tube and the ratio of lower port internal diameter are 1 ︰ 0.3 ~ 1 ︰ 0.6; The upper port internal diameter of conical tube is 50 ~ 100mm, and the upper port internal diameter of conical tube is equal with the circular port internal diameter of dividing plate.
Described ash bucket is made up of 1 ~ 4 sub-ash bucket, and sub-ash bucket is arrangement in " one " font, and every sub-hopper bottom is equipped with sewage draining exit, and each sewage draining exit is all equipped with valve.
Owing to adopting technique scheme, the utility model has following good effect:
1) the utility model is primarily of inlet box, fumer, lower box, scrubber tube and ash bucket composition, and whole apparatus structure is simply compact, volume is little, can meet the demand at backfill for underground gob-side entry retaining of coal mine filling process.
2) sewage draining exit is provided with immediately below lower box of the present utility model, the sewage quantity of discharging in the sewage draining exit unit interval is identical with all spray spouts and the Washing spray nozzle unit interval interior total Water sprayed, the water level observation window of lower box indicates waterline, when the water level in lower box is concordant with the waterline of water level observation window, regulate the valve at sewage draining exit place, the sewage flowed out from sewage draining exit enters filling pump by pump, realizes water reuse, using water wisely, avoids the waste of water resource.
3) when dusty gas enters inlet box from airscoop shroud, under the effect of inlet box top swash plate, dusty gas is uniformly distributed in inlet box, the water smoke that dusty gas sprays with spray spout mixes, part dust in dusty gas is wetted and trapped by drop, drop on together with drop on dividing plate, flow in lower box through scrubber tube.Because the lower port of scrubber tube is positioned at 50 ~ 80mm place under the horizontal plane of lower box, along with dusty gas continue pass into, the pressure in inlet box increases gradually, in inlet box, do not entered scrubber tube under the effect of the pressure by the dusty gas that drop traps; Separately because spray header and spray spout installation site are lower than the cover mouth of airscoop shroud, even if the very large drop that also can not blow away spray spout ejection of dusty gas speed entered from airscoop shroud cover mouth, ensure that the efficiency with spraying and dedusting that is uniformly distributed of drop.
4) because the scrubber tube caliber in the utility model reduces from top to bottom gradually, therefore moisture film can be formed at the tube wall of scrubber tube from the drop spray spout spray.Enter the dusty gas of scrubber tube, the drop of a part of dust wherein under the middle position of scrubber tube is directly sprayed by spray spout trap, the moisture film that another part dust then sticks to scrubber tube tube wall is captured, thus flow in lower box with current, some dust then enters through scrubber tube in the water of lower box and is washed, therefore adding efficiency of dust collection, efficiency of dust collection is high.
5) when entering the dusty gas in lower box and being washed the water surface of rear effusion lower box, the dust now in dusty gas is almost captured to the greatest extent; Because dusty gas is comparatively large in the muzzle velocity of scrubber tube, water droplet can be evoked at the water surface of lower box, now, even if also containing dust in dusty gas, still can mix further with the water droplet that the water surface evokes, trapped further.Then, when the airflow uniform distribution plate of the gas containing water droplet in fumer is evenly distributed, then enter demister and carry out gas-water separation, thus reduce the content of water droplet in Exhaust Gas.
6) the utility model often works a period of time, can wash according to Washing spray nozzle in actual conditions fumer to demister, ensures that dust removal process continues efficiently to carry out.
Therefore, this device has water saving, volume is little, structure is simple and efficiency of dust collection high, can meet the demand used in backfill for underground gob-side entry retaining of coal mine filling process process.
