Abstract

The utility model relates to a multipurpose three-return pressure-free boiler with a vertical water pipe, which comprises a housing, a furnace liner, a base, a smoke flue, a back smoke chamber, a furnace door, furnace bars, a slagging door, and an ace-shaped boiler bottom which is arranged at the upper part of a combustion chamber. An arc-shaped water cavity is arranged in the arc-shaped boiler bottom, a plurality of vertical water pipes are arranged at the upper part of the water cavity and are communicated with a high-temperature water cavity which is arranged at the upper part of the furnace liner, and the back smoke chamber is provided with a preheating water cavity. The utility model has the advantages of simple structure, long service life, convenient maintenance, convenient ash and scale removal, quick water boiling, and safety without pressure. The utility model can be guaranteed to run for a long term with high efficiency and energy saving, and can be used for heating and bathing.

Description

Many with vertical water pipe three backhaul pressure-less boilers

The utility model belongs to a kind of life use stove tool, particularly a kind of boiler of making fuel with solid.

Pressure-less boiler is the heat power equipment that extensively adopts during people live, be generally single return structures, the medium of boiler for domestic is a hard water, and the gradient of horizontal water tube is generally less than 12 degree, and diameter is less than 133 millimeters, water in the water pipe can't be in a tumult to static, the temporary hardness of water and the fouling of permanent hardness are very serious, can't clear up, thereby cause pair heat poor, red-hot flame and high-temperature flue gas force pipe overheated, pipe break when serious.In addition, the red-hot flame of single backhaul boiler and high-temperature flue gas stream are too short to have left stove very soon, and heat waste is very big, and the thermal efficiency is very low, returns environment simultaneously and brings severe contamination.Advanced in recent years double-grate boiler improves to some extent on combustion system, but structurally be unable to do without horizontal water tube, fouling can't be cleared up, effect worse and worse in the use, there are many stoves in two or three years just can't use, its main cause is: the fouling of (1) horizontal water tube is difficult to cleaning, damages also to be difficult to repair; (2) flue gas flow is very short often is capped with heating surface, and cleaning is difficulty relatively, has a strong impact on to pay heat, and boiler can't normally be moved.

The purpose of this utility model provide a kind of simple in structure, the life-span long, easy to maintenance, deashing snaking convenient, boiling water is fast, can guarantee many usefulness vertical water pipe three backhaul pressure-less boilers of long-term energy-efficient operation.

For realizing the purpose of this utility model, the utility model comprises the chimney at flue in the shell, shell, the base under the shell, rear portion and rear smoke chamber and fire door, fire bars, cleanout door, the characteristics of this stove are at the bottom of the bottom of a pan on top, combustion chamber is arc-shaped pot, the arc water cavity is arranged at the bottom of the arc-shaped pot, water cavity top has many vertical water pipes to communicate with the high temperature water cavity on flue top, gives hot-water cavity in the rear smoke chamber.The top of furnace shell is provided with hand-hole, and Explosion-proof cap is housed on the hand-hole.There is the heat convection pipe to communicate in the rear smoke chamber with hot-water cavity.

This boiler structure is simple, the incrustation scale that the temporary hardness of water is difficult for deposition and utilizes hand-hole, hand-hole to enter clearing up very easily in the shell at the bottom of many vertical water pipes and the arc-shaped pot etc. locate, thus increased service life.

The red-hot flame of combustion chamber and high-temperature flue gas are crossed firebreak through the top of courage and are entered many vertical water pipe heat transfer zone, enter rear smoke chamber by rear pass again, form the N shape flow direction and discharge from chimney then, therefore the flow process that has prolonged flue gas has improved exerting oneself and the thermal efficiency of boiler greatly.Flue dust is because the inertia major part is concentrated the bottom that is deposited on high-temperature flue gas outlet and heat convection space, and opening shoot door can be easily clean with the flue dust full scale clearance.And the dedusting of leading to self has reduced environmental pollution, thereby the cleannes that kept heating surface, improved a pair thermal effect, guarantee long-term energy-efficient operation, burned flame and hot flue gas are through the combustion chamber, many vertical water pipe zones and rear smoke chamber, the heat exchange of three backhauls, thermal efficiency all-the-time stable is more than 75%.The needs of people's life have been satisfied in enforcement of the present utility model, and heating and have a bath and can move simultaneously also can be used for heating separately, is a kind of novel stove and accessory popular to people.

The concrete structure of utility model is provided by following examples and accompanying drawing.

Fig. 1 is the utility model structural representation.

Describe specific structural details of the present utility model and working condition in detail below in conjunction with Fig. 1.

As figure, it comprises base (1), cleanout door (2), water inlet pipe (3), fire door (4), combustion chamber (5), at the bottom of the arc-shaped pot (6), shell (7), flue (8), vertical water pipe (9), firebreak (10), thermometer (11), outlet pipe (12), high temperature water cavity (13), liquid level gauge (14), steam vent (15), hand-hole (16), Explosion-proof cap (17), chimney (18), give hot water outlet (19), rear smoke chamber (20), give hot-water cavity (21), heat convection pipe (22), rear casing (23), shoot door (24), rear pass (25), running water inlet (26), arc water cavity (27), blowdown base (28), fire bars (29).Linked to each other by fire door (4) rear pass (25) between flue (8) and the shell (7), rear casing (23) links to each other with shell (7), and (6) link to each other at the bottom of flue (8) top and the arc-shaped pot.Be provided with Explosion-proof cap, blast pipe (15), liquid level gauge (14), thermometer (11) for guaranteeing that safety does not have on the shell of pressure (7).Be provided with hand-hole (16), blowdown base (28) in order to keep in repair and clear up incrustation scale.For dedusting is provided with shoot door (24), flue dust is discharged from shoot door (24), has guaranteed the cleannes of heating surface.Water enter between flue (8) and the shell (7) by water inlet pipe (3) and arc water cavity (27) heating after vertical water pipe (9) rises, heating enters high temperature water cavity (13) once more, high-temperature water flows out from outlet pipe (12), for heating or use such as have a bath.Because the heat exchange of (6) the flowing of high temperature water cavity (13), arc water cavity (27) and vertical water pipe (9) water of all can being in a tumult at the bottom of the pressure and arc-shaped pot of backwater, the deposition of temporary hardness of water and the structure of minimizing permanent hardness have been avoided.Running water enters from running water inlet (26) and gives hot-water cavity (21) hot water after heat convection pipe (22) heat exchange and flow out for having a bath usefulness from giving heat outlet (19).Fuel is dropped in above the fire bars (29) by fire door (4), in the combustion chamber that good ignition condition is arranged (5) fire burns, red-hot flame and high-temperature flue gas upwards flow in flue (8), radiation heat transfer climbs over then in firebreak (10) inflow many vertical water pipes (9) zone and carries out the secondary radiation heat exchange, enter the 3rd backhaul from rear smoke chamber (25) when arriving the bottom, in rear smoke chamber (20), carry out heat convection, after waste heat passed to heat convection pipe (22) and give hot-water cavity (21), through the radiation of three backhauls, become low-temperature flue gas after the heat convection and enter atmosphere from chimney (18).Slag after the burning is discharged from cleanout door (2).
