Abstract
The utility model relates to a water-seal ash discharger for duster, which is characterized in that the water-seal ash discharger for duster comprises a water tank (7) which is provided with an opening at the top and contains water, an ash falling cylinder (4) connected with the ash falling opening of the ash separator, a seal plate (5) connected with the lower end of ash falling cylinder (4) and inserted into the water tank (7); the box body of the water tank (7) is communicated with the cavity body the ash falling cylinder (4). The air leakage phenomenon of the ash falling cylinder of the utility model can not appear, the dusting efficiency can be improved largely, the discharged dust concentration is only 83.7 mg /mark meter, and the dusting efficiency of the ash separator can reach about 93%. The water-seal ash discharger for duster can be widely used as the water seal device of the dry dust catcher.
Description
The utility model relates to a kind of dust arrester.
At present, China is except that minority heat power plant boiler deduster adopts electrostatic precipitation, and the deduster of most Industrial Boilers, kiln adopts two types of moisture film wet dust removal and dry type cyclone dust removals more.Dry type cyclone dust removal does not have good measure because of manufactory to the ash hole sealing problem, the air short circuit, deduster having been collected be deposited in dust in the ash bucket to produce flies upward for the second time, dust collector efficiency reduces greatly, the efficiency of dust collection that causes the dry type cyclone dust collectors only about 80%, dust exhausting concentration does not reach discharging standards, causes atmospheric air to pollute.The common efficiency of dust collection of wet type water film dedusting is about 90%, but it costs an arm and a leg, and the sour water discharging causes secondary pollution, often because of the hydraulic pressure shakiness, causes the moisture film rupture of membranes, and flue gas with water causes air-introduced machine blade knot ash, air-introduced machine vibrations and draw bad footing, the shutdown maintenance of having to.
The purpose of this utility model is to provide a kind of deduster water-stop ash discharging gear of installing at the deduster ash hole, can prevent the short circuit of air, improves dust removing effects.
The technical solution of the utility model is: the inside that it comprises the top opening fills the water tank of water, the ash dropping cylinder that is connected with the deduster ash port, is connected with the lower end of ash dropping cylinder and inserts the sealing plate in the water tank; The casing of described water tank is connected with the cavity of ash dropping cylinder.When dust falls in the water in the water tank, progressively be accumulated in the water tank, because sealing plate is isolated outside air and ash dropping cylinder, so during the water level of the negative pressure in the ash dropping cylinder in drawing high ash dropping cylinder, can not make the air short circuit in outside air and the ash dropping cylinder, thereby make the air that falls fly upward, cause secondary pollution.
The utility model compared with prior art has following advantage:
Owing to installed sealing plate and water sealing device additional, can not occur in the ash dropping cylinder leaking out, so can improve efficiency of dust collection greatly, according to surveying and determination, dust exhausting concentration only is 83.7 a milligrams/mark rice, be far smaller than the standard of 200 milligrams/mark of the dust exhausting concentration rice of State Bureau of Environmental Protection's regulation, the efficiency of dust collection of deduster can reach about 93%.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is a structural front view of the present utility model;
Accompanying drawing 2 is a structure vertical view of the present utility model; Wherein:
［ 1 ］. short tube; ［ 2 ］. inspection opening; ［ 3 ］. inspection cover; ［ 4 ］. ash dropping cylinder; ［ 5 ］. sealing plate; ［ 6 ］. the control of dust swash plate; ［ 7 ］. water tank; ［ 8 ］. the ash discharge swash plate.
Embodiment: referring to accompanying drawing 1 and accompanying drawing 2, it is rectangular ash dropping cylinder ［ 4 ］ that the inside that it comprises the top opening fills the water tank ［ 7 ］ of water, the cross section that is connected with the deduster ash port, be connected with the lower end of ash dropping cylinder ［ 4 ］ and insert sealing plate ［ 5 ］ in the water tank ［ 7 ］; The casing of described water tank ［ 7 ］ is connected with the cavity of ash dropping cylinder ［ 4 ］.Water in the water tank ［ 7 ］ generally fills with, but during the work of the air-introduced machine above the deduster ash port, atmospheric pressure in the ash dropping cylinder ［ 4 ］ is lower than ambient atmosphere pressure, so the water level of ash dropping cylinder ［ 4 ］ below can rise, and the water level in the water tank ［ 7 ］ can descend, described sealing plate ［ 5 ］ is sheet and extends to the inner chamber of water tank ［ 7 ］ along ash dropping cylinder ［ 4 ］ wall portion, the purpose of sealing plate ［ 5 ］ is exactly when preventing that water level in the water tank ［ 7 ］ from descending, the air short circuit of ash dropping cylinder ［ 4 ］ inner chamber and water tank ［ 7 ］ top causes the dust of whereabouts to fly upward out ash dropping cylinder ［ 4 ］.The side wall portion of described ash dropping cylinder ［ 4 ］ is provided with the inspection opening ［ 2 ］ with ash dropping cylinder ［ 4 ］ intracavity inter-connection, be covered with inspection cover ［ 3 ］ on this inspection opening ［ 2 ］, when error, water in the water tank ［ 7 ］ adds and causes the air short circuit less, wet ash can be located by the up short tube ［ 1 ］ that is bonded in, and just can open inspection opening ［ 2 ］ short tube ［ 1 ］ is dredged this moment.Described ash dropping cylinder ［ 4 ］ is connected with flange plate type with the deduster ash port.The sidewall of the water tank ［ 7 ］ of described ash dropping cylinder ［ 4 ］ below is provided with intilted control of dust swash plate ［ 6 ］, can make the dust that falls into water tank ［ 7 ］ bottom enter the bottom of water tank ［ 7 ］.The wall box portion away from ash dropping cylinder ［ 4 ］ of described water tank ［ 7 ］ is provided with intilted ash discharge swash plate ［ 8 ］, is convenient to remove the mud shape dust of water tank ［ 7 ］ bottom.
