The bottom of a boiler cylinder of the boiler is in a crescent shape, and the lower part of the boiler cylinder forms a main blast chamber and a quadratic blast chamber, wherein the front part of the quadratic blast chamber is provided with a fire-resisting water wall, and the back part is provided with a heat-collecting water tank; water fire pipes are arranged among the fire-resisting water wall, the heat-collecting water tank and the boiler cylinder; gas among the water fire pipes form smoke gas passages, and a deflecting plate is slantwise arranged between the quadratic blast chamber and a back smoke box and is in a double-layer structure; the interlayer of the deflecting plate forms a water jacket which is communicated with the boiler cylinder, and a smoke passage is formed between the bottom of the water jacket and a bottom plate of the boiler. The boiler cylinder of the utility model increases the heating area and the heat efficiency, and the fire-resisting water wall, the water fire pipes and the deflecting-type water jacket are used for collecting the heat and the dust. After testing, the dust exhausting density is 178.29 mg/nm<3>, and the Ringelman index of the smoke gas is smaller than 1 stage.
Description
The utility model relates to a kind of smokeless micronic dust hot-water heating boiler, belongs to the designing technique of normal-pressure horizontal hot-water heating boiler.
Existing similar boiler is owing to be subjected to the restriction of body of heater internal structure, the flue gas that in combustion process, produces, could discharge after must handling through dust arrester, and dust arrester can make the resistance of fume emission increase in running, causing must be by air-introduced machine air inducing, form negative-pressure firing, like this, in boiler and subsidiary engine, air-introduced machine, deduster have then become essential corollary equipment, and the increase that the caused floor space of these corollary equipments increases, boiler room civil engineering expense increases, the increase of equipment purchasing expense certainly will cause heat cost.And in the dust arrester except that water deduster other deduster then can only solve dust removal problem, and can not solve the blackness of exhaustion problem.
The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, and provide a kind of under the situation that adopts the coal pressure combustion of loosing, do not use air-introduced machine, deduster, pass through chimney directly to the airborne release flue gas by boiler body, and reach the extremely low smokeless micronic dust hot-water heating boiler of dust exhausting concentration.
The purpose of this utility model is achieved in that it comprises parts such as drum, fire grate, combustion chamber, pyrotechnics pipe, extreme misery pipe, smoke box, chimney.Boiler drum bottom is crescent shape, and its below constitutes main chamber and secondary combustion chamber from front to back successively, and the crescent shape drum of main chamber top and level are oblique vertical the putting of 10-20 degree angle lapping, and the crescent shape drum of secondary combustion chamber top is horizontal; The secondary combustion chamber front portion is provided with the fiery waterwall of retaining, the rear portion is provided with heat collection water tank, keeps off the extreme misery pipe connection by horizontally set of fiery waterwall and heat collection water tank, and both both sides all are communicated with drum, top is communicated with drum by the vertical extreme misery pipe that is provided with, and the crack constitutes exhaust gases passes between the extreme misery pipe; The oblique deflection plate that is provided with between secondary combustion chamber and the back smoke box, this deflection plate is a double-decker, its interlayer constitutes the water jacket that is communicated with drum, constitutes flue between this water jacket bottom and the drop-bottom.
The utility model compared with prior art has the following advantages and good effect:
1, is provided with secondary combustion chamber at boiler drum bottom, flue gas broken away from enter secondary combustion chamber behind the main chamber to burn away, thereby eliminate black smoke until after-flame;
2, drum is designed to crescent shape, has increased heating surface area, has improved the thermal efficiency;
3, keep off fiery waterwall and extreme misery pipe at main chamber end and the indoor secondary that is provided with respectively of second-time burning,, also play making the soot dust granule bump and the effect of the control of dust that falls except as the heat collector;
4, the flue gas baffle means that constitutes of the folded plate type water jacket of smoke box front portion, back, can thermal-arrest again can control of dust, controlled the excessive of flue dust to greatest extent.
5, be discharged into flue gas Lin Geman index in the atmosphere＜1 grade after tested, dust exhausting concentration is 178.29mg/nm

The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross sectional representation of drum of the present utility model.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model embodiment is made up of drum 1, front smoke box 2, main chamber 3, fire grate 4, shoot door 5, the fiery waterwall 6 of retaining, extreme misery pipe 7,8,14, heat collection water tank 9, secondary combustion chamber 10, body of heater 11, back smoke box 12, baffle plate type water jacket 13, chimney 15, pyrotechnics pipe 16.The design of the utility model drum 1, the intensity that has taken into full account pressure combustion is lower than negative-pressure firing intensity, so drum 1 bottom design is become crescent shape, its below constitutes main chamber 3 and secondary combustion chamber 10 from front to back successively, the crescent shape drum 1 and the level of main chamber 3 tops is oblique vertical the putting of 15 degree angle lappings, and the crescent shape drum 1 of secondary combustion chamber 10 tops is horizontal; Circle round in order to help flue gas, to greatest extent flue dust is trapped in the stove in the dust collect plant, the utility model is provided with the fiery waterwall 6 of retaining in secondary combustion chamber 10 front portions, the rear portion is provided with heat collection water tank 9, keep off extreme misery pipe 7 connections of fiery waterwall 6 and heat collection water tank 9 by horizontally set, both both sides all are communicated with drum 1, and top is communicated with drum 1 by the vertical extreme misery pipe 8,14 that is provided with, and the crack constitutes exhaust gases passes between the extreme misery pipe.Keep off the smoke evacuation sectional area sum of crack formation between smoke evacuation sectional area that the crack constitutes between the vertical extreme misery pipe 8 that is provided with in fiery waterwall 6 tops smoke evacuation sectional area constitutes greater than crack between the vertical extreme misery pipe 14 that is provided with in heat collection water tank 9 tops and the extreme misery pipe 7 that keeps off horizontally set between fiery waterwall 6 and the heat collection water tank 9.By this structural design, extreme misery pipe 8 of the present utility model is three, and extreme misery pipe 7 and extreme misery pipe 14 are respectively 11 and 12.The utility model is the oblique deflection plate that is provided with between secondary combustion chamber 10 and back smoke box 12 also, and this deflection plate is a double-decker, and its interlayer constitutes the water jacket 13 that is communicated with drum, constitutes flue between the base plate of these water jacket 13 bottoms and body of heater 11.Back of the present utility model smoke box 12 is divided into two smoke boxes by dividing plate, simultaneously also with pyrotechnics pipe 16 separated into two parts, after laying respectively at two in the smoke box, flue gas enters front smoke box 2 by smoke box after by part pyrotechnics pipe 16 like this, enter another back smoke box by another part pyrotechnics pipe 16 again, be discharged in the atmosphere by the chimney 15 that is communicated with this smoke box at last.
