Description
Technical field
The utility model relates to a kind of vertical boiler, especially relates to the non-smoke and-dust energy-saving boiler of a kind of coal, gas mixed combustion.
Background technology
Along with improving constantly of people's quality of life, people are also more and more higher to environment requirements.Coal-burning boiler is all adopted in the most of regional heating in the north at present; in order to ensure environmental problem; the efficiency of dust collection of coal-burning boiler, effect are the major issues that various places environmental administration pays close attention to the most; the coal-burning boiler that those smoke evacuation dirt are exceeded standard carries out severe sanction and deduction; coal-fired bearing boiler will move; necessary high-power air-introduced machine of adapted and expensive water mill deduster, thereby will consume great amount of water resources and consume a large amount of electric energy, so increased the operating cost of boiler greatly.Normal-pressure boiler generally adopts no chimney straight-line flue dust, and deduster can't be installed, thus must the expensive smokeless environment-friendly matchmaker of burning, can not use other coal, otherwise smoke evacuation dirt severe overweight, pollution that can be a large amount of surrounding enviroment.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and burns fully, good dedusting effect, fuel savings, non-smoke and-dust energy-saving boiler that environment protecting is good.
The utility model is realized in the following way:
A kind of non-smoke and-dust energy-saving boiler, comprise shell, flue, burner hearth, delivery port, water inlet, outlet flue, establish flue damper in the outlet flue, it is characterized in that: be provided with the pyrotechnics heat exchanger that is approximate king's font distribution in the above-mentioned flue, space in itself and the flue forms five backhaul flue gas flows, burner hearth is provided with the firebreak that is approximate several fonts along axis direction, firebreak top is provided with the high temperature chimney arch, the both sides, middle part are provided with flame export, be provided with the perpendicular yi word pattern wall with flues that is that links to each other with firebreak at the flame export place of both sides, lower furnace portion is provided with the inclined ventilation and blocks, the bottom is provided with slag notch;
Be provided with coal, the mixed right chamber of gas in the upper end at described flame export place;
Each pyrotechnics turning at described pyrotechnics heat exchanger is provided with an ash door;
Described high temperature chimney arch is camber;
The middle part of blocking in described inclined ventilation is provided with lower wind door, top is provided with middle air door;
Described high temperature chimney arch and described being between the perpendicular yi word pattern wall with flues form secondary furnace;
Form trade on the flame between described pyrotechnics heat exchanger and the described flue, the trade communicates with described secondary furnace on the flame;
The place is provided with coal feeding hole at described burner hearth;
Be provided with the dedusting mouth in the described bottom that is perpendicular yi word pattern wall with flues;
Bottom at described shell is provided with water return outlet.
The utility model has following effect:
1) the smoke abatement effect is remarkable: the utility model is provided with in flue and is level
The pyrotechnics heat exchanger that font distributes, space in itself and the flue forms five backhaul flue gas flows, thereby the flow process that has prolonged flue gas greatly, at burner hearth along being provided with the firebreak that is the П type on the axis direction, firebreak top is provided with the high temperature chimney arch, increase coal gas at the flame export place and mixed the combustion chamber, make the fuel gas and the pernicious gas that do not participate in burning in the burner hearth originally fully, beans, coal dust, tar, after passing through flame export, in the flame secondary furnace because the radiation of high temperature chimney arch, carry out abundant mixed combustion after the convection current, make these materials fully burn consumption totally, flue dust falls into the flue dust chamber, flame trade on the pyrotechnics enters the pyrotechnics heat exchanger of five backhauls, thereby soot emissions are few, and environment protecting is good.
2) thermal efficiency height is saved coal-fired; The utility model since boiler bottom fire grate is not set, so coal is not subjected to the restriction of fire grate, disposable burner hearth is filled it up with after, coal-fired in burner hearth under the promotion of gravity, automatically glide, finish drying, do processes such as slide, burning, cooling, last slag notch is discharged.Fire box temperature is stable like this, sufficient combustion, combustion intensity height, add the five backhaul flue gas flows that the trade is formed on the utility model pyrotechnics heat exchanger and the pyrotechnics, prolonged the flue gas heat exchange flow process, increased the time of heat exchange, thereby improved the thermal efficiency, saved valuable fire coal.
3) small investment, cost is low: because the utility model need not be purchased huge, complicated cleaner is installed again, is utilized boiler body inside just to reach dust removing effects, greatly reduce acquisition cost and operating cost.
4) be fit to local various fuel: the utility model is because the special construction of itself, thereby can use local various types of fire coal, and soot emissions are lower than national specified discharge standard, and hot water, steam can be provided.Be widely used in industrial and mineral, supply water in enterprises and institutions, office, school, residential quarters etc., heating.
