Abstract
A kind of boiler New-type boiler case dust collecting, comprises sack cleaner, also comprises high pressure positive blower and dust collection chamber; High pressure positive blower is connected with the outlet of sack cleaner, is provided with an ash bucket below sack cleaner; Be connected by negative-pressure pipeline between sack cleaner with dust collection chamber, the free end of negative-pressure pipeline is suspended in the top of dust collection chamber; The bottom of dust collection chamber and ash bucket is respectively arranged with ash discharging hole.Dust block board is suspended in the central authorities of dust collection chamber, and the both sides of dust block board are affixed with the sidewall of dust collection chamber respectively; Rotary type air channel is formed between dust block board and dust collection chamber's sidewall.The utility model structure is simple, volume is large, resistance is little, cost is low, easy care, can carry out preliminary thick purification, avoid airborne dust to the ash content in case; Efficiency of dust collection is high, wide adaptability, can collect most of dust; Adopt dry operation, do not need to there is not secondary pollution with water, mainly by synergy such as inertial collision, directly interception, diffusion and gravitational settlings.
Description
Technical field
The utility model relates to a kind of dust collecting, a kind of device collecting dust in boiler case time special.
Background technology
Boiler case forms framework by hanging hanger erection I-steel, channel-section steel, angle bar etc., forms closure, sealing furnace roof header and liaison tube, and form drum cell at drum place outside the top and surrounding of framework by welding steel.Actively administering for leaking out at present, under this reality in major overhaul process, needing to clear up casing interior dust stratification.Dust emission is often up to more than 500 ~ 5000mg/m, and this concentration is considerably beyond the state emission standard of 10mg/m.Because structure of container often needs labor cleaning, the large efficiency of workload is low.If do not take effective dust suppression, let alone free diffusing, will seriously pollute working environment and air, serious harm is caused to human body and equipment.Healthy in order to ensure workman, raises labour efficiency, does thermal power plant's dust collection work well very urgent.
Because large casing interior area irregularity gap is narrow and small, current manner of cleaning up is mainly labor cleaning, at substantial human and material resources.Staff utilizes the packed ash of knit nylon to transport recycling elevator from manhole door and transports to soot, and this series of activities is loaded down with trivial details, efficiency is low and easy secondary pollution environment, has a strong impact on workman's health and operating efficiency.
Utility model content
The utility model is the technological deficiency for mentioning in background technology, provides a kind of structure simple, can carry out the device of primary collection to dust in case.
The technical scheme realizing above-mentioned purpose employing is: a kind of boiler New-type boiler case dust collecting, comprises sack cleaner, also comprise high pressure positive blower and dust collection chamber; High pressure positive blower is connected with the outlet of sack cleaner, is provided with an ash bucket below sack cleaner; Be connected by negative-pressure pipeline between sack cleaner with dust collection chamber, the free end of negative-pressure pipeline is suspended in the top of dust collection chamber; The bottom of dust collection chamber and ash bucket is respectively arranged with ash discharging hole.
Dust collection chamber is closed cavity, and its inside is provided with dust block board, and by plurality of plates, in " bow " shape, arrangement forms described dust block board.
Described dust block board is suspended in the central authorities of dust collection chamber, and the both sides of dust block board are affixed with the sidewall of dust collection chamber respectively; Rotary type air channel is formed between dust block board and dust collection chamber's sidewall.
The mouth of pipe that dust sucting pipeline and negative-pressure pipeline are placed in dust collection chamber is separately installed with screen pack.
Compared with prior art, the utility model structure is simple, volume is large, resistance is little, cost is low, easy care, can carry out preliminary thick purification, avoid airborne dust to the ash content in case; Efficiency of dust collection is high, wide adaptability, can collect most of dust; Adopt dry operation, do not need to there is not secondary pollution with water, mainly by synergy such as inertial collision, directly interception, diffusion and gravitational settlings.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: high pressure positive blower 1, sack cleaner 2, dust block board 3, ash bucket 4, ash bucket ash discharging hole 5, negative-pressure pipeline 6, dust collection chamber 7, dust collection chamber's ash discharging hole 8, dust sucting pipeline 9.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
See accompanying drawing 1, this novel disclosed this boiler New-type boiler case dust collecting, comprises high pressure positive blower 1, sack cleaner 2, dust block board 3, ash bucket 4, ash bucket ash discharging hole 5, negative-pressure pipeline 6, dust collection chamber 7, dust collection chamber's ash discharging hole 8, dust sucting pipeline 9.
Wherein: high pressure positive blower is connected with the outlet of sack cleaner, be provided with an ash bucket below sack cleaner, be communicated with sack cleaner dust mouth, ash bucket bottom center is provided with ash discharging hole.Be connected by negative-pressure pipeline between sack cleaner with dust collection chamber, the free end of negative-pressure pipeline is suspended in the top of dust collection chamber.The bottom center of dust collection chamber is provided with dust collection chamber's ash discharging hole.Dust sucting pipeline is connected with dust collection chamber bottom, and dust sucting pipeline end is provided with blow device.Dust sucting pipeline is generally flexible pipe.Dust collection chamber is closed cavity body structure, and the free end of negative-pressure pipeline is inserted on its top board, and top board is detachable.Dust collection chamber's ash discharging hole is provided with valve plate.
Dust collection chamber inside is provided with dust block board, and by polylith monomer plate, in " bow " shape, arrangement forms dust block board.Dust block board is suspended in central authorities of dust collection chamber, and the both sides of dust block board are affixed with the sidewall of dust collection chamber respectively; Rotary type air channel is formed between dust block board and dust collection chamber's sidewall.
The mouth of pipe that dust sucting pipeline and negative-pressure pipeline are placed in dust collection chamber is separately installed with screen pack.
Under the large suction of high pressure positive blower, dust sucting pipeline through blow device by a large amount of dust absorbings in case in dust collection chamber, when dusty gas is by after entering dust collection chamber, the coarse grained dust in large face is stopped by dust block board and falls, less dust is then along with air-flow together enters sack cleaner through negative-pressure pipeline, dust-contained airflow is through deduster through Bag filter, and part dust leans on gravity landing to bottom ash discharging hole; Part adsorbing powder dust is on cloth bag.Air after purification, under suction function, by dust contained in removing gas, is discharged by blower fan mouth.Under the whole dust removal process of dusty gas is all in negative pressure condition, and vacuum size is controlled by frequency conversion fan and inlet valve.Accumulate dust in equipment in use for some time, must be discharged by ash discharging hole, a place is the ash discharging hole of the ash bucket of sack cleaner bottom, the ash discharging hole bottom another Chu Shi dust collection chamber.This task has been come by Hand-operated butterfly valve.Sack cleaner, through clearing up after a while, can not set up vacuum after preventing blocking.
