Description

Horizontal multi-chamber, multi-reverse running and multi-purpose atmospheric boiler

The present invention relates to a kind of hot-water boiler, is a kind ofly both can warm oneself the horizontal multi-chamber, multi-reverse running and multi-purpose atmospheric boiler of can drink water simultaneously again, having a bath.

At present, the boiler kind of selling on the market is a lot, the flue tube boiler that the '30s is arranged, water jacket boiler is also arranged, immediate with the present invention is " horizontal many backhauls of water jacket water pipe normal-pressure boiler ", its patent No. is 892007214, and this boiler is made up of three parts, the one, and the combustion chamber water jacket, the 2nd, both sides collector pipe and rear water collecting pipe, the 3rd, ellipse garden shape water tank, coal by rear blocking plate back both sides collector pipe, enter chimney discharge by rising on the water tank bottom, ellipse garden at water jacket bottom combustion product gases, this furnace thermal efficiency is higher, can reach 76%, but also have following problem: 1, the thermal efficiency is also low, also has the potential to be tapped; 2, flue gas flow direction is also not too reasonable, does not make full use of heat energy; 3,, can only warm oneself and not have its usefulness with single; 4, dust removing effects is poor, goes back over-emitting black exhaust.

The purpose of this invention is to provide a kind of horizontal multi-chamber, multi-reverse running and multi-purpose atmospheric boiler, be difficult for regulating to solve heat supply temperature, the thermal efficiency is low, the single and dust removing effects difference problem of purposes.

The object of the present invention is achieved like this: with burner hearth make three of left, center, rights or about two, hearth water sleeve independently separately, the left and right sides of each burner hearth, front and back and top are to be communicated with water jacket, on the leading flank of each hearth water sleeve fire door is arranged, flue is arranged on the trailing flank, in the flue back outer collector pipe is arranged, left and right sides collector pipe and rear water collecting pipe combine as a whole, be collectively referred to as outer collector pipe, outer collector pipe outside is the furnace shell water jacket, and back and top are to be communicated with water jacket about it, two water inlet pipes about its preceding bottom has, going up thereafter mid point has pipe to be communicated with the fire division wall water jacket, and the fire division wall water jacket is concave shape, is sitting in the upper back of hearth water sleeve.Concordant with lateral surface behind the burner hearth.Furnace shell inwall in top on it, under touch furnace bottom, leave flue between itself and the furnace shell front end, be provided with the internal layer collector pipe between fire division wall and the hearth water sleeve both sides, the left and right sides, internal layer collector pipe left and right sides posterior angle communicates with outer collector pipe, going up the angle before its left and right sides is connected with each hearth water sleeve trailing flank respectively, be connected with hot water jacket by pipe at each hearth water sleeve upper top, hot water jacket is arch moon shape, and its front center has chimney, and there is outlet pipe its rear end, be equipped with the burner hearth collector pipe at each hearth water sleeve internal upper part, and be communicated with each other, there is water inlet pipe its lower end, and there is outlet pipe the upper end.

Cold water front portion under the furnace shell water jacket both sides enters, from the back, put the pipe outflow again and entered mid point on the fire division wall water jacket, again by the forward lower comer of fire division wall water jacket cross respectively pipe flow out enter about the forward lower comer of outer collector pipe, mid point is crossed pipe respectively and is flowed out the posterior angle, the left and right sides that enters the internal layer collector pipe from the rear side of outer collector pipe again, cross pipe by the preceding upper end of left and right sides internal layer collector pipe respectively again and flow out mid point under the rear portion that enters each hearth water sleeve respectively, cross pipe by the preceding upward angular vertex of each hearth water sleeve respectively then and enter hot water jacket, the middle part is crossed pipe and is flowed out body of heater behind the hot water jacket at last, walks six backhauls altogether.

Flue gas moves towards four backhauls: coal is respectively in each hearth water sleeve internal combustion, flue gas directly burns outer rear side collector pipe through burner hearth rear side flue, wraparound forward about dividing by the back again, to the wraparound backward again of the flue between fire division wall water jacket and furnace shell, burn the internal layer collector pipe, and then, discharge from chimney at last by the flue of rear end below flue enters arch moon shape hot water jacket wraparound forward.

This invention compared with prior art has the following advantages: (1) makes three or two hearth water sleeves with burner hearth, and is not only independent but also unified, is very beneficial for the user to freely the selecting and controlling of amount of heat, thus fuel savings, manpower and the energy; (2) cold water and flue gas adverse current help exchange heat; (3) be provided with furnace shell water jacket, fire division wall water jacket, ectonexine collector pipe, total heating surface amass big, can increase 1-1.5 doubly; (4) nearly four-six backhauls of backhaul are moved towards in flue gas, water route, and Btu utilization is abundant; (5) because the many good dedusting effect of flue gas backhaul; (6) be provided with the burner hearth collector pipe, it is many that purposes becomes, and heating can be taken warm water, boiling water simultaneously; (7) adopt gravity-flow ventilation, without air blast and air-introduced machine, small investment, power saving, province's maintenance cost; (8) volume is little, economizes steel, and cost is low; (9) without refractory brick, the light durable just fortune of body, lifting is convenient.
