Abstract
The utility model relates to a smoke and dust eliminating water heating furnace. A furnace ash bin and an ash outlet are positioned on the lower part of a furnace body. A furnace bar, a furnace chamber and a coal inlet are arranged above the furnace ash bin. The inner side of the wall of a furnace casing is provided with a water jacket provided with a water inlet pipe and a water outlet pipe. The water jacket is communicated with a main and a subsidiary water tanks. A fire pipe is arranged in the water tank. The end parts of the fire pipe are respectively communicated with a flame path and an exhaust gas path, and a pumping outlet is communicated with the exhaust gas path. The flame path is arranged on a rear wall or a side end. The rear wall and the side end are arranged at the part which is a bit lower than the center of the high temperature combustion region of the furnace chamber. When coal is added to the furnace, pulverized coal can not directly go into the flame path, and only a small part of dust goes into the flame path following exhaust gas. When the exhaust gas goes into the flame path, the flow speed decreases. The exhaust gas sinks to a dust eliminating chamber at the lower part of the furnace body under the action of gravitation. The utility model has the advantages of no dust pollution of the discharged exhaust gas and high thermal efficiency.
Description
The utility model relates to a kind of medium heater with thermal source, is the improvement to existing dedusting hot-water boiler.
At present, the various hot-water boilers that people use generally are from fire door coal, furnace bottom and advance air, and directly extracting waste gas out by chimney or air-introduced machine from the top of flame is that flue dust and pernicious gas are discharged to the air from chimney, causes environmental pollution.Even increase fume treatment auxiliary, air pollution also are difficult to avoid.Simultaneously, this boiler also exists the low shortcoming of the thermal efficiency.
The utility model purpose is to avoid above-mentioned weak point of the prior art and a kind of improved smoke abatement and dust control hot-water boiler is provided, thereby reaches the purpose of non-environmental-pollution and energy savings.
The purpose of this utility model is achieved by the following technical solution:
The smoke abatement and dust control hot-water boiler comprises body of heater 1, coal filling hole 2, grate 3, burner hearth 4, ashes storehouse 5, ash hole 6, quirk 7,8, fire tube 9, flue 10,11 and bleeding point 12, water jacket 13, main water box 14, secondary water tank 15, dirt pocket 16 in forming.Ashes storehouse 5 and ash hole 6 are positioned at body of heater 1 bottom, and top, ashes storehouse is provided with grate 3, burner hearth 4 and coal filling hole 2.Water jacket 13 is located at furnace shell wall inboard, and communicates between major and minor water tank, which is provided with entery and delivery port 17,18.Many fire tubes 9 place water tank, and its end communicates with quirk 7,8 and flue 10,11 respectively, and bleeding point 12 communicates with flue 10.Key improvements part of the present utility model is quirk 8 is located at the rear wall or the side at burner hearth 4 middle parts, that is the center of burner hearth high temperature combustion zone portion's side on the lower side.After bunker coal added burner hearths from coal filling hole 2, the moving down of smaller volume and bottom slag when burning along with it entered high temperature combustion zone.The waste gas that flame and burning produce, is flow to outside the stove by bleeding point 12 through fire tube 9, quirk 7, flue 11,10 by quirk 8, forms airway path.
Structures shape of the present utility model during coal coal dust can not directly enter quirk, and have only seldom a part of dust to enter quirk with waste gas.But, cause the waste gas flow velocity to descend because quirk 8 is positioned at the side at burner hearth 4 middle parts.At this moment, in the dirt pocket 16 of dust below the effect of gravity sinks down into body of heater bottom, quirk 8.
Because the utility model is located at quirk the side at burner hearth middle part and has set up dirt pocket, exhaust gas discharged no dust pollution in use, thermal efficiency height.
Accompanying drawing is the structural representation of the utility model embodiment.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The utility model comprises body of heater 1, coal filling hole 2, grate 3, burner hearth 4, fire exploring hole 19, ashes storehouse 5, ash hole 6, quirk 7,8, fire tube 9, flue 10,11, flue dividing plate 20 and bleeding point 12, water jacket 13, main water box 14, secondary water tank 15, dirt pocket 16 in forming.Ashes storehouse 5 and ash hole 6 are positioned at body of heater 1 bottom, and top, ashes storehouse is provided with grate 3, burner hearth 4 and coal filling hole 2, and the fire exploring hole 19 that communicates with burner hearth is positioned at the coal filling hole bottom.Flue dividing plate 20 places among the flue 10, plays guide functions.Water jacket 13 is located at furnace shell wall and furnace bottom inboard, and communicates by communicating pipe 21,22 between major and minor water tank, and water nationality, water jacket are provided with entery and delivery port 17,18.Many fire tubes 9 are vertically put in the sub-water tank, and its end communicates with quirk 7,8 and flue 10,11 respectively, and bleeding point 12 communicates with flue 10.Quirk 8 is located at the rear wall at burner hearth 4 middle parts, and the position is corresponding on the upper side with fire exploring hole, that is portion position on the lower side, the center of burner hearth high temperature combustion zone.In raw coal is added into burner hearth 4,, enter heat zone because of coal combustion moves down.Because air is to be inhaled into burner hearth 4 from coal filling hole 2, three positions of fire exploring hole 19 and ash hole 6 upper, middle and lower relative with quirk 8 inlet, a large amount of oxygen and pyrocarbon combustion reaction in the air makes the high-temp combustion aggravation, and the fire bed in the burner hearth is thickeied.When rising to 800 ℃ of left and right sides, produce combustibles such as coal tar and flammable sulphur.Along with fuel move down and air-flow enters the high-temperature region and participates in burning, eliminated pollution simultaneously thereby improved furnace temperature.Because coal dust can not directly enter quirk 8 during coal, have only seldom a part of dust by quirk, when the waste gas that flame and burning produce passed through quirk 8, the waste gas flow velocity descended, and dust falls under gravity into the dirt pocket 16 at secondary water tank rear portion.The dirt pocket bottom is provided with ash hole 23, the dust that is deposited when flowing in quirk with regular removing flue gas.The flue gas that flows out from quirk 8 flow to quirk 7 through fire tube because the obstruct of flue dividing plate 20, air-flow turn the back by flue 11 again by fire tube 9 flue 10 of flowing through, be discharged to outside the stove by bleeding point 12.When quirk, fire tube, waste gas road junction flowed, making quirk, fire tube, flue was outward that heat-conducting medium in water jacket, the water tank is heated at high-temp waste gas.After cold water flowed into from water inlet 17, the water that flows to top entered the upper water cover after by the main water box of flowing through communicating pipe; Another part water water jacket below furnace bottom, the ashes storehouse of flowing through under the effect of pressure continues upwards to flow after absorbing the ashes waste heat.Water after being heated flows out from delivery port 18.So circulation realizes heat energy conversion.
Coal-firedly in the burner hearth provide sufficient oxygen for giving, on coal filling hole 2 and fire exploring hole 19, ash hole 6, establish the lid 24 that has pore respectively.The big I of pore is determined according to the kind of fire coal.
