Description

Horizontal non-brick multi-return atmospheric boiler

The utility model relates to a kind of hot-water boiler, is a kind ofly both can drink water, have a bath the efficient normal-pressure boiler of horizontal no many backhauls of brick multipotency that can warm oneself again simultaneously.

At present, the boiler kind of selling on the market is a lot, and the flue tube boiler of 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 hot-water boiler ", and its patent No. is 892007214, and this boiler is made up of three parts, the one, the combustion chamber water jacket, the 2nd, both sides collector pipe and rear side collector pipe, the 3rd, oval water tank, coal burns in the water jacket bottom, flue gas enters the chimney discharge by rear blocking plate back both sides collector pipe by rising on the oval water tank bottom.This furnace thermal efficiency is that raising is arranged, and can reach 76%, but also has following shortcoming: (1) 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) single can only the heating of purposes not has its usefulness; (4) dust-laying effect is poor, goes back over-emitting black exhaust.

The purpose of this utility model provides the efficient normal-pressure boiler of a kind of horizontal no many backhauls of brick multipotency, and is low to solve the thermal efficiency, the single and dust removing effects difference problem of purposes.

The purpose of this utility model is achieved in that makes a hearth water sleeve with burner hearth, its both sides, front and back and top all are the water jackets that is communicated with, on its leading flank fire door is arranged, flue is arranged on the trailing flank, in the flue back outer collector pipe is arranged, its left and right sides collector pipe and rear water collecting pipe are connected as a single entity and are collectively referred to as outer collector pipe, outer collector pipe outside is the furnace shell water jacket, back and top all are to be communicated with water jacket about it, two water inlet pipes about its preceding bottom has, thereafter the middle and upper part has and fire division wall water jacket communicating pipe, and the fire division wall water jacket is concave shape, and seat is concordant with lateral surface behind the burner hearth in the hearth water sleeve upper back.Furnace shell inwall in top on it touches down furnace bottom, leaves flue between itself and the furnace shell front end, between fire division wall and the hearth water sleeve, be provided with the internal layer collector pipe, internal layer collector pipe posterior angle communicates with outside collector pipe, goes up the angle before the left and right sides and is connected with the hearth water sleeve trailing flank respectively, be arch moon shape at the hearth water sleeve upper top by the pipe hot water jacket that is connected with hot water jacket, its front center has chimney, and its end has outlet pipe, is provided with the burner hearth collector pipe at the hearth water sleeve internal upper part, there is water inlet pipe its lower end, and there is outlet pipe the upper end.Cold water enters from about furnace shell water jacket lower front portion, mid point on the some inflow fire division wall water jacket from the back, the forward lower comer of outer collector pipe about entering respectively by the preceding bottom of fire division wall water jacket again, enter the posterior angle of left and right sides internal layer collector pipe again from outer collector pipe upper back, the upper end enters mid point under the hearth water sleeve rear portion again before the internal layer collector pipe of the left and right sides, enters hot water jacket by going up angular vertex before the burner hearth by pipe then; The middle part is crossed pipe and is flowed out body of heater, totally six backhauls behind the hot water jacket at last.Flue gas moves towards four backhauls: coal is in the hearth water sleeve internal combustion, flue gas directly burns outer rear side collector pipe through flue, wraparound (between furnace shell and fire division wall water jacket) forward about dividing by the back again, flue place through between fire division wall water jacket and furnace shell, wraparound backward again, burn the internal layer collector pipe, and then by after enter arch moon shape hot water jacket lower flue wraparound forward, discharge from chimney.

This utility model compared with prior art has the following advantages: (1) cold water and flue gas adverse current help exchange heat; (2) it is long-pending big to be provided with furnace shell water jacket, fire division wall water jacket, ectonexine collector pipe total heating surface, can increase 1-1.5 doubly; (3) flue gas, that current move towards backhaul is many, Btu utilization is abundant; (4) because the flue gas backhaul is many, good dedusting effect; (5) purposes is many, and heating simultaneously can be for drinking-water, warm water; (6) adopt gravity-flow ventilation, without air blast and air-introduced machine, small investment is economized maintenance cost, power saving; (7) volume is little, economizes steel, and cost is low; (8) without refractory brick, body is gently durable, convenient transportation.
