Abstract
The utility model relates to a civil strong stove with high efficiency and energy saving, which belongs to the technical field of combustion and heat exchange, which comprises a hearth, siphons, thread pipelines, and a screw heat exchanger. The siphons are lengthways arranged above the hearth along the circumference of a stove opening. A grate and a slag catching dustpan are distributed under the hearth. A fume passage on the left direction of the hearth is distributed with the thread pipelines transversely and slantways. The screw heat exchanger is distributed above the whole stove body transversely. Fume flow paths of the utility model are designed into a reverse S shape. The utility model has the advantages of sufficient heat exchange, high heat efficiency, and less fume discharge.
Description
The utility model belongs to burning and heat transfer technology field, further relates to a kind of energy-efficient civilian heavy-duty furnace.
Domestic burners than extensive use mainly contains at present: honeycomb briquette domestic burners and bulk coal-fired domestic burners two big classes.Honeycomb briquette stove is mainly used in family's kitchen and indoor heating, but this stove mainly comes air in the heating clamber by the heat radiation of stove itself and stovepipe in when heating, and efficient is low, and the air drying is less economical.Bulk coal-fired domestic burners is mainly used in small city and rural area, and effect also is kitchen and heating, still dispels the heat by furnace stack during heating and heats room air, and simultaneously, above-mentioned honeycomb domestic burners pollutes also very serious.Also help above-mentioned two kinds of stoves and directly add water jacket simply and carry out indoor heating, but do not take all factors into consideration, so its effect is all very poor from water circulation, burning, heat transfer aspects because of it.The civil heating stove of traditional structure adopts vertical structure more, flue gas from bottom to top motion under the draft effect of chimney, with stove in after the heating surface heat exchange of arranging row to atmosphere.The heating stove of vertical structure is at small-power (D＜20KW) be widely adopted in the scope, but, it (is just running into difficulty in the process of the development of D＞20KW) to high-power, because increase along with the heating stove thermal power, the height that certainly will want corresponding increase body of heater is to arrange more heating surface, but, to this civil heating equipment, consider to making things convenient for user's cooking, it highly is limited, usually can not be greater than 1 meter, therefore, many vertical high-power heating stoves do not possess the cooking function on the market.
The utility model purpose is to overcome the defective of above prior art, the energy-efficient civilian heavy-duty furnace that provides a kind of employing to fall " S " type flue gas flow.
The utility model comprises burner hearth, siphon pipe, threaded tube, spiral heat exchanger.The burner hearth top vertically is furnished with siphon pipe around fire door, the burner hearth below is furnished with fire grate and residue receiving dustpan, and the exhaust gases passes lateral inclination of burner hearth left is furnished with threaded tube, and whole body of heater top laterally is furnished with spiral heat exchanger.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a siphonal structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further.
The utility model is made up of burner hearth 18, siphon pipe 16, threaded tube 5, spiral heat exchanger 7.Burner hearth 18 tops vertically are furnished with siphon pipe 16, and siphon pipe 16 is arranged around fire door, is stamped fire-suppressing cover 12 on the fire door, and bell 9 is stamped in whole body of heater top, and whole exhaust gases passes exit is furnished with fire banking-up board 10.Burner hearth 18 belows are furnished with fire grate 18 and residue receiving dustpan 19, and the exhaust gases passes lateral inclination of burner hearth 18 lefts is furnished with threaded tube 5, and whole body of heater top laterally is furnished with spiral heat exchanger 7.
The utility model has adopted following technology:
1. fall " S " type flue gas flow.The utility model falls " S " type flue gas flow, when it is highly greatly reduced, also has the following advantages: a. flue gas distance of flowing through is long, and the interior heat exchange of stove is abundant; When b. flue gas turns round at water-cooled plate washer place, can isolate in the flue gas part fly ash particle to connecing garbage container, thereby its discharging flue dust is greatly reduced.
2. adopt the siphon pipe technology, the utility model has been arranged some siphon pipes above burner hearth, as accompanying drawing 2.It is to utilize the density contrast of water in the inside and outside sleeve pipe to realize enhanced heat exchange.Concrete heat transfer process is: inner sleeve is suspended among the outer tube, temperature rises the water in the ring-like zone that inside and outside sleeve pipe forms owing to accept from the radiant heat of burner hearth, density reduces, like this, water in the inside and outside sleeve pipe has produced motion owing to density is different, radiant heat in the burner hearth constantly absorbs-takes away by the water in the sleeve pipe-absorb-takes away again again, and diabatic process constantly goes on.
3. adopt the screwed pipe technology, this heavy-duty furnace has adopted the some screwed pipes that are in tilted layout.Studies show that, because the existence of screw thread, destroyed the boundary layer of flow of flue gas, strengthen the disturbance between the flue gas, thereby reduced the thermal resistance of fume side, strengthened heat exchange, its coefficient of convective heat transfer α is 1.4 times of common light pipe, and because the existence of screw thread, the soot particle in the flue gas is difficult for attached on the tube wall and influence the heat exchange effect.After it is in tilted layout, the separation of two phenomenon be can not occur in the pipe, heat exchange and circulation are beneficial to.
4. adopt the adverse current spiral tube exchanger, this heavy-duty furnace accomplishes that really heating water does not mix mutually with health hot water, and the user can relieved use health hot water.Its operation principle is: utilize heating water to add heat medium water as heat medium water and heat health hot water in the spiral heat exchanger, and the health water inlet is arranged in heating coolant-temperature gage highest point, has strengthened the temperature and pressure of water-water heat exchange, has strengthened heat exchange.And, flowing in pipe because health hot water is independent, it can be with pressure work, and this moment, body of heater still moved under normal pressure.
Below the utility model accompanying drawing is described: in the accompanying drawing 1,1 is base, and 2 for connecing garbage container, 3 is heat-insulation layer, and 4 is water jacket, and 6 is shoot door, 8 is fin, 11 is pressure relief opening, and 13 is delivery port, and 14 is the health water inlet, 15 is in the health water out accompanying drawing 2,20 is inner sleeve, and 21 is outer tube, and 22 is shrouding.
