Description

Horizontal full-drivepipe multi-return-stroke multipurpose atmospheric boiler

The utility model relates to a kind of hot-water boiler, is a kind ofly both can warm oneself, horizontal a complete set of many backhauls of the pipe multipurpose standard pressure boiler that can drink water again, have a bath 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 water collecting 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 higher, can reach 76%, but also has following problem: (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) purposes is single, can only warm oneself and not have its usefulness; (4) dust removing effects is poor, goes back over-emitting black exhaust.

The purpose of this utility model provides a kind of horizontal a complete set of many backhauls of pipe multipurpose standard pressure boiler, 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 that communicates with the top all around with burner hearth, on its leading flank fire door is arranged, flue is arranged on the trailing flank, in the flue back rear water collecting pipe is arranged, there is the left and right sides collector pipe hearth water sleeve both sides, be divided into two parts up and down by the fire division wall water jacket, peripheral furnace shell also is divided into two parts up and down, the back is for being communicated with water jacket about the furnace shell lower part, forward lower comer has water inlet pipe, and the rear portion has and top communicating pipe, and back and top are for being communicated with water jacket about furnace shell top, going up mid point before it is connected with the lower floor collector pipe, upper strata collector pipe rear lower is connected with the lower floor collector pipe, and lower floor's collector pipe forward lower comer is connected with mid point on the furnace shell water jacket front side by pipe, and the preceding upper top of hearth water sleeve is communicated with hot water jacket by pipe, hot water jacket is arch moon shape, end has outlet pipe, and front end is fixed with chimney, is provided with the burner hearth collector pipe in hearth water sleeve, there is water inlet pipe its lower end, and there is outlet pipe the upper end.

Cold water enters from the left and right sides, the preceding lower part of furnace shell water jacket inferior horn, cross pipe from upper end mid point thereafter and flow out the back bottom centre enter furnace shell top, cross pipe from the front upper part mid point of furnace shell upper strata water jacket again and flow out about the preceding bottom enter lower floor's collector pipe two jiaos, again backward from the rear portion of lower floor's collector pipe mid point cross pipe and flow out mid point under the rear portion that enters the upper strata collector pipe, then forward from about the front portion of upper strata collector pipe on two the angle cross pipe and flow out mid point under the rear portion that enters hearth water sleeve, cross the pipe outflow from the front upper part mid point of hearth water sleeve again and enter hot water jacket, cross pipe from hot water jacket rear portion mid point at last and flow out body of heater, walk six backhauls altogether.

Flue gas moves towards four backhauls: coal is in the hearth water sleeve internal combustion, flue gas directly burns lower floor's collector pipe through the left and right sides through flue, by after wraparound forward, walk around fire division wall water jacket wraparound backward upwards again, the straight upper strata collector pipe that burns, and then by after enter below the arch moon shape hot water jacket flue wraparound forward, discharge from chimney again.

This utility model compared with prior art has the following advantages: (1) cold water and flue gas adverse current help exchange heat; (2) be provided with furnace shell water jacket, fire division wall water jacket, levels collector pipe, total heating surface amass big, can increase 1-2.5 doubly; (3) flue gas, that current move towards backhaul is many, Btu utilization is abundant; (4) because the many good dedusting effect of flue gas backhaul; (5) purposes is many, and heating simultaneously can be for drinking-water and warm water; (6) adopt gravity-flow ventilation, without fermented soya beans, salted or other wise blower fan and air-introduced machine, small investment, power saving; (7) volume is little, economizes steel, and cost is low, and (8) without refractory brick, body is light, durable good transportation.
