Description

Square chest type three backhaul normal-pressure hot-water boilers

The utility model relates to a kind of square chest type three backhaul normal-pressure hot-water boilers.

The normal-pressure hot-water boiler that uses at present mostly is vertical boiler, generally adopts the double-layer inverse burning formula, but all is single backhaul, because its vertical structure restriction can not be designed to two return or many backhauls, so a large amount of heats is discharged from very soon and slatterns, the thermal efficiency is not high.Simultaneously, carry a large amount of dust in the flue gas of its discharge and contaminated environment, it is also relatively large that its vertical structure takes up room, and its heating area is little, generally in 5000 square metres.

The purpose of this utility model is to provide that a kind of thermal efficiency height, quick heating, consumption coal are few, discharging reaches the environmental requirement standard, and heating area is big, simple in structure, cost is low, installation, operation, horizontal three backhaul normal-pressure hot-water boilers easy to maintenance.

The technical solution of the utility model is: this boiler comprises square box shape body of heater shell (12), body of heater inner casing (13), horizontal water tube (20) in the body of heater, the slag chute of body of heater bottom (37), the fire bars on slag chute top (2), the cleanout door of slag chute front end (1), the door (3) that pokes fire on slag door (1) top, the smoke pipe of upper of furnace body (21), be characterized on the top of fire bars (2) water pipe furnace grate (5) formed by water pipe by one, in the upper end of water pipe furnace grate (5) is that the middle part front end has a smoke baffle plate (9) in the body of heater, in the rear end of smoke baffle plate (9) lower cover (26) is arranged, leave the space between the rear wall of the rear end of lower cover (26) and body of heater inner casing (13) so that the flue gas rising is passed through; There is a upper cover plate (24) rear end, top in body of heater, leaves the space between its front end and body of heater inner casing (13) antetheca so that the flue gas rising is passed through; Smoke pipe (21) is arranged at the rear end of upper of furnace body; Atmospheric communicating pipe (17) is housed at the top of body of heater; On the shell (12) of the upper front end of water pipe furnace grate (5), have coal-feeding door (6), the water pipe (34) once in the bottom of body of heater, one outlet pipe (33) is arranged at top, return pipe (34), the cavity of outlet pipe (33) between body of heater shell (12) and body of heater inner casing (13) are interconnected with the water pipe and the some horizontal water tubes (20) of water pipe furnace grate (5); One ash-pit (38) that falls is arranged in the lower end, rear portion of body of heater.

Characteristics of the present utility model are at the top of described body of heater front end one shoot door (11) to be arranged, and there is a back shoot door (25) rear end of upper of furnace body, is provided with several deashing hand holes (4) in other position corresponding to horizontal water tube (20) of body of heater.

Characteristics of the present utility model are in described upper of furnace body water level meter (15), thermometer (16) and dispensing mouthful (14) to be housed also, correspond to the ash-pit place in the side of body of heater and have side shoot door (36), moisturizing base (32) is housed, blowdown base (31,35) in the lower end of body of heater.

Advantage of the present utility model and effect: because the three backhaul thermal-arrest modes of employing have enlarged heating surface area, so thermal efficiency height reaches 78% through the actual measurement thermal efficiency.Quick heating, province's coal are compared energy-conservation 25%-30% with other boiler of the same nominal thermal efficiency, and soot emissions simultaneously also greatly reduce, and significant smoke abatement and dust control usefulness is arranged.Heating area is big, reaches 2000-15000 square metre.And simple in structure in addition, cost is low, installation, operation, easy to maintenance, need not rouse advantages such as (drawing) blower fan with gravity-flow ventilation.

Fig. 1 is the utility model structural representation.

Fig. 2 is the left view (boiler face view) of Fig. 1.

Fig. 3 has vertical view for Fig. 1.

As Fig. 1, Fig. 2, fire coal is fed on the water pipe furnace grate (5) from coal-feeding door (6), carries out the burning first time, and the less coal cinder of the volume that does not burn falls to and carries out the burning second time on the fire bars (2).High-temperature flue gas is owing to stopped by smoke baffle plate (9) and lower cover, so can only move up to the middle part of body of heater from the rear portion of body of heater, be subjected to stopping of upper cover plate (24) this moment again, can only move up to the top of body of heater from the front portion of body of heater, discharges from the smoke pipe (21) of rear end then.Through the motion of three backhauls, the speed that flue gas is discharged greatly reduces, and the some horizontal water tubes (20) in the body of heater fully are heated.Oarse-grained flue dust is owing to being slowed down the speed of service by lower cover (26), stopping of upper cover plate (24), rear portion from body of heater falls to the ash-pit (38) with the collision of horizontal water tube (20) in addition, in in the body of heater, the dust on top can go out clearly from last shoot door (11) and back shoot door (25), clear up several hand holes (4) that can before and after body of heater, be provided with simultaneously.Water at low temperature enters cavity between body of heater shell (12) and the body of heater inner casing (13) from return pipe (34), sends from delivery port (33) after the water pipe in horizontal water tube (20), water pipe furnace grate (5) is heated, and so moves in circles.

Among Fig. 1,7-coal-feeding door frame, 8-furnace bottom shrouding, the upper deashing doorframe of 10-, 16-temperature gauge pipe End socket in the seat, 18-, 19-outside head, 22-smoke pipe flange, 23-smoke shelf plate, 27-fixed head.

Among Fig. 2,29-is the water connecting leg between the upper nowel, the 30-base.
