Abstract
The utility model relates to a dust collecting equipment, specially relates to a steam humidification shielding and dedusting system for coal handling system. The steam humidification shielding and dedusting system includes a feed down pipe, a No.1 transfer station, a crusher, a No.2 transfer station, a No.3 transfer station and a roller grizzly, the discharging port coal hose pipes of the No.1 transfer station, the crusher and the No.2 transfer station are provided with a steam humidification shielding dust collector respectively. The beneficial effects of the utility as follows: every transfer station feed down pipe of coal handling system is provided with a steam atomizer, forming a 'steam curtain', when coal particles pass by the 'steam curtain', the surface of the coal particles is attached with a water film, which makes the pulverized coal mutually adsorbed without forming flying dust, collection efficiency is about 90%, visibility is good and ensures safety production. The utility model steam humidification shielding and dedusting system can be used at the dedusting place with a powder material conveyor.
Description
Technical field
The utility model relates to cleaner, specifically relates to a kind of steam humidification shielding dust pelletizing system of coal handling system dedusting.
Background technology
The technology that coal handling system dedusting is at present generally adopted is the cyclone dust collectors dedusting, its operation principle is: after dust-contained airflow enters cyclone dust collectors by air inlet pipe, become circular motion by rectilinear motion, outer rotational gas flow flows downward twist along tube wall, density falls to entering ash releasing tube greater than the grit of gas at action of centrifugal force lower edge tube wall, purified gas is discharged by interior rotational gas flow, also takes a part of grit out of, forms the secondary dust pollution.1), coal handling system generally will be through three transfers in actual production the weak point that coal handling system is used the cyclone dust collectors dedusting is:, primary fragmentation, a screening process, the cyclone dust collectors of three terminals, the gas that has tiny coal dust of discharging when the dedusting operation is directly arranged to the plant working place, make coal dust concentration over-standard in the workshop air, cause secondary pollution, directly threaten the health of plant personnel.Form more dust during 2), be discharged on next bar belt, through terminal next time at the dust of two cyclone dust collectors ash releasing tubes at disintegrating machine and rolling cylinder sieve place.The cyclone dust collectors that have are subjected to spatial constraints, the cylindrical shell insufficient height, and separated grit is taken away by the eddy current of bottom again, and dust drains into outside the belt porch, and whole workshop condition is caused secondary pollution again.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiency that prior art exists, and a kind of three transfers of coal handling system of eliminating are provided, the steam humidification shielding dust pelletizing system of the dust that produces in the primary fragmentation, screening process.
The utility model steam humidification shielding dust pelletizing system is achieved by following technical proposals: the utility model steam humidification shielding dust pelletizing system comprises feed opening, No. 1 terminal, disintegrating machine, No. 2 terminals, No. 3 terminals, drum screen, and described No. 1 terminal, disintegrating machine and No. 2 terminal discharging opening coal elephant trunk places respectively are provided with steam humidification shielding deduster.
The utility model steam humidification shielding dust pelletizing system has following beneficial effect compared with prior art: owing to be provided with steam-jet sprayer at each coal handling system terminal feed opening place, form " steam curtain ", when coal charge passes through from " steam curtain ", coal charge surface attachment water membrane, fine coal is adsorbed mutually can't form flying dust, effectively stoped particulate coal to produce new coal dust simultaneously; " steam curtain " can be enclosed in the coal dust that produces and heat up in a steamer in the coal bin in terminal feed opening and disintegrating machine, drop on the belt with particulate coal and to carry, play the effect of shielding dust, fly upward thereby limited coal dust, No. 1 coal conveyer belt corridor, operation place, No. 2 coal conveyer belt corridor coal dust concentration are respectively: 2.73mg/m
3, 2.26mg/m
3, it is original about 10% that Dust Capacity has only, and efficiency of dust collection reaches about 90%, and visibility good has guaranteed safety in production.The utility model steam humidification shielding dust pelletizing system can be applicable to the dedusting place of all granular material conveyers.

Fig. 4 is the utility model steam humidification shielding dust pelletizing system steam-jet sprayer section structure schematic diagram.
Wherein: 1, feed opening; 2, No. 1 terminal; 3, disintegrating machine; 4, No. 2 terminals; 5, No. 3 terminals; 6, drum screen; 7, coal elephant trunk; 8, steam-jet sprayer; 9, spraying aperture.
The specific embodiment
Below in conjunction with drawings and Examples the utility model steam humidification shielding dust pelletizing system technical scheme is further described.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model steam humidification shielding dust pelletizing system comprises 1, No. 1 terminal 2 of feed opening, 4, No. 3 terminals 5 of 3, No. 2 terminals of disintegrating machine, drum screen 6, and described No. 1 terminal 2, disintegrating machine 3 and No. 2 terminal 4 discharging opening coal elephant trunks 7 places respectively are provided with steam-jet sprayer 8.
Described steam-jet sprayer 8 is made the rectangle frame for steel pipe, and the tube wall inboard is drilled with spraying aperture 9 around the steel pipe frame, and steel pipe one end of steam-jet sprayer 8 is connected other end solder up with vapour source.
Embodiment 1.
With the steel pipe manufacturing steam-jet sprayer 8 of Φ 15mm, as shown in Figure 3, Figure 4,, and around the steel pipe frame, evenly bore the spraying aperture 9 of making Φ 3mm on the inboard tube wall with steel tube bending rectangularity frame, steel pipe one end is connected with vapour source, other end solder up; The steam-jet sprayer of making 8 is fixedly welded on defeated 2, No. 2 terminals 4 of No. 1 terminal of coal and disintegrating machine 3 discharging opening place blanking bin inwalls respectively.The special-purpose steam branch pipe of dedusting is installed in main steam range, is connected to steam-jet sprayer 8 main steam header imports, each steam-jet sprayer 8 is connected on the main steam header.
When failing the coal operation, open the steam-jet sprayer steam valve that is arranged on main steam range place, when coal charge passes through from steam-jet sprayer 8, pass to steam, water membrane is just adhered on the coal charge surface, fine coal is adsorbed mutually can't form flying dust, effectively stoped particulate coal to produce new coal dust simultaneously; " steam curtain " can be enclosed in the coal dust that produces and heat up in a steamer in the coal bin in terminal feed opening and disintegrating machine, drop on the belt with particulate coal and carry, and plays the effect of shielding dust, flies upward thereby limited coal dust, and operation place dust concentration is reduced.By to first, second terminal and this three roads steam curtain of disintegrating machine mouth, the moisture film on coal charge surface still exists when the 3rd terminal and screening machine place, does not need to increase " steam curtain " again, and dust concentration can not exceed standard.
