The utility model has the advantages of the high combustion efficiency of the general coal stove, strong fire power, less ash flying, etc.

Description

Automatic blast gasification coal stove

The utility model relates to a kind of small-sized mixed gas producer, particularly relates to a kind of family expenses gasification coal furnace, can be widely used in cooking, heating and the hot water supply of family and catering industry.

At present, the coal furnace that supplies family to be used for cooking, heating and hot water supply in the prior art has varied but the ubiquity efficiency of combustion is on the low side, and a little less than the firepower, flying dust is many, shortcomings such as ash disposal is seriously polluted, thereby often can not meet the demands aspect use and the environmental sanitation.For overcoming the deficiencies in the prior art and defective, a kind of household small-size gas generator has appearred in recent years, or title gasification coal furnace, but this kind type of furnace generally adopts the electric power air blast, equipment is many, power consumption again, and bottom water seal and ash disposal system complex structure, operation inconvenience, thereby be difficult to apply.

One of the purpose of this utility model is that this system does not need electric power, and can realize the air blast uniform and stable for the gasification coal furnace provides a kind of controllable automatic blower system.

Another purpose of the present utility model is for the gasification coal furnace provides a fixed water seal simple in structure ash handling equipment of holding concurrently, thereby it is easy to operate to reach ash disposal, and can realize the wet type ash disposal, avoids environmental pollution.

The purpose of this utility model is achieved in that it is to set up automatic steam one air ejection system on the basis of gasification coal furnace, this system comprises a jacket type steam generator that has inner rib plate that is positioned at the reducing zone top, one is the pressure balancing tank of its continuous water supply, gas solid separator, steam jet, mixing chamber, air channel and moisturizing, water draw-off.After the water in the steam generator is heated generation steam, part steam passes through gas solid separator, spray at a high speed through steam jet, thereby form negative pressure in the porch, to enter burner hearth after Air Entrainment, the mixing, form steam one air ejection phenomenon, thereby do not need the electric power air blast to achieve the above object.

Another characteristics of the present utility model are to adopt the fixed water seal ash handling equipment of holding concurrently, and this device is by the stove skirt that is positioned at the fire grate bottom, ash disposal mouth, water tank and water supply system composition.Inject a certain amount of water in the water tank, the stove skirt inserts in the case, forms water seal, and realizes the wet type ash disposal.

Accompanying drawing 1 is a structural principle schematic diagram of the present utility model.

Accompanying drawing 2 is the horizontal sectional view of steam generator.

Accompanying drawing 3 be steam through spout, behind mixing chamber and the air channel, the structural principle schematic diagram when entering the stove skirt.

Following structure accompanying drawing describes concrete structure of the present utility model and enforcement in detail:

Automatically steam one air ejection system comprises a jacket type evaporimeter (1) that has inner rib plate and a pressure balancing tank (2) that is positioned at the reducing zone top, solid and gas separator (3), steam jet (4), mixing chamber (5), air channel (6) and moisturizing, water draw-off.When the water of evaporimeter (1) be heated produce steam after, part steam enters the top of pressure balancing tank (2) along pipeline, another part then sprays at a high speed through steam jet (4) by separator (3), porch at mixing chamber (5) forms negative pressure, air is entrainmented, mixes the laggard air channel (6) of going into, pass stove skirt (7) and fire grate (8), enter burner hearth then, produce carbon monoxide and hydrogen with scorching hot burning coal layer effect, be mixed gas, again through fire door and auxiliary air mixed combustion.

When another part steam enters the top of pressure balancing tank (2), be stored in the pressure balancing tank water since its headroom be subjected to steam generator in the effect of uniform pressure, action principle according to linker, compensator (2) will be to steam generator (1) moisturizing, thereby guarantee the steam continuous injection, the water in jar uses until exhausted.In the time of need adding water, but steam off valve A and moisturizing valve B open discharging valve C, by funnel (10), replenish magnetized drinking water through water mangetizer (9) in its jar, to prevent fouling.During moisturizing, need the bonnet of safety regulating valve door (11) is taken off, deflate, this safety regulating valve has the effect of overvoltage protection concurrently.

Steam generator (1) is the toroidal pressure vessel that has inner rib plate (16), the effect of fin both can increase the intensity of container, can increase heating surface again, guaranteed when getting angry or add water after steam spray and can start fast, and higher aerogenesis pressure and sufficient gas production are arranged.

The effect of separator (3) is to avoid steam to carry silt, prevents that nozzle is blocked.It is utilize steam unexpected dilatation, reduction of speed and zig zag centrifugal action with get rid of with sand grain.

Air channel (6) is looped around the top of stove skirt (7), is flat convergent shape, and purpose is to guarantee that the static pressure on each cross section, air channel is equal substantially, to realize balanced ventilation.

The aperture of control valve B can be regulated the quantity of steam of injection, thereby regulates the size of firepower, when desiring to turn off the blast, can open drain valve D, with the water emptying in the compensator (2).

The water seal ash handling equipment of holding concurrently adopts fixedly, and it is by the stove skirt (7) that is positioned at the fire grate bottom, ash disposal mouth (13), water tank (12) and water filling system compositions such as (15).When ash disposal mouth (13) is sealed by lid (14), inject a certain amount of water by (15) to water tank (12), because stove skirt (7) inserts in the water tank, form water seal, when the steam ejection air carries out air blast, because the water-column of water seal greater than blast pressure, makes gas spray to the fire grate top, and can not leak from the bottom.When needing ash disposal, lid can be opened, ash is clawed from the stove skirt of fire grate bottom, realize the wet type ash disposal, thereby reduce pollution environment.

Upper of furnace body at stove, heating, the hot-water supply system that can adopt backheat to utilize, this system is by water jacket (21), smoke returning flue (20), smoke-refeed mouth (17), water inlet (18), delivery port (19) and flue (22) are formed, and this system both can utilize smoke discharging residual heat preferably, can doublely be cooking, heating and supply domestic hot-water again, also can change the top water pipe into storage heater, realize air heating.

Two kinds of the tapered and tubulars of the different designs of the visual fuel of burner hearth of the present utility model, thereby various diffusing coals of burning and moulded coal.According to user's different needs, can also make single fire hole, two fire holes or three fire holes.

The utility model is compared with general coal furnace, it is higher to have efficiency of combustion, the advantages such as firepower is prosperous, and flying dust is few are compared with existing gasification coal fired stove, owing to increased a kind of automatic steam one air ejection system and adopted the fixed water seal ash handling equipment of holding concurrently, in the situation that does not increase investment, not only save electric power, and simplified the structure and operate, and can realize wet ash removal, effectively improved reliability and cleannes, thus easy to utilize.
