Abstract

The utility model discloses a boiler, in particular to an energy-saving environment protection gasification boiler, which comprises a flue (3) that comprises an outer layer (1) and an inner layer (2). The utility model is characterized in that the bottom of the inner layer (2) is pyramidal and provided with an ash falling port (15), and the outside flue (3) of the pyramid is provided with a wind pipe (5) is connected with an interface (11) and an opening of tuyere (6), and the interface (11) reaches outside of the outer layer (1), and the head of the opening of tuyere (6) reaches inside of the lower pyramid of the inner layer (2), an ash against board (8) is arranged at the ash falling port (15), and the ash against board (8) is positioned on a slide way (7). The utility model supplies wind on the fuel in the combustion chamber directly and over the combustion chamber, which makes the fuel burn sufficiently, and the dust particles of the coal gas produced during burning can re-burn when lifting up in the hearth, which is not only saving fuels, but also solving the problem of the discharging coal gas and dust particle outside, thereby the utility model improves the thermal efficiency and protects the environment. The bottom of the inner layer is pyramidal, which solves the problem of forming a dead corner during burning, and the utility model can save energy source about 30 percent.

Description

Energy-saving environment-friendly gasification boiler

Technical field:

The utility model relates to a kind of boiler, particularly a kind of energy-saving environment-friendly gasification boiler.

Background technology:

Existing miniature boiler structure is by a flue of being made up of outer and internal layer, the inside bottom of flue is provided with fire grate, the fire grate top is the combustion chamber, being provided with stove hall pipe above the combustion chamber is communicated with flue, the vertical setting that stove hall pipe has, what also have is horizontally disposed with, the top is provided with smoke exhaust pipe, flue connects hot water outlet and cold water is answered back, below fire grate, tap into wind apparatus, during use, be coated with heat-insulation layer in outer field outside, hot water outlet that links to each other with flue and cold water are answered back and are connect valve control device, produce the water heating of heat after being positioned at the fuel combustion on the fire grate to flue and stove hall pipe, send into through pipeline and to use thermic devices, heat radiation back cold water is back in the flue and is heated, circulation repeatedly.Required air quantity is blown to the fire grate below by airduct by air blast and supplies with during fuel combustion.The power consumption of the boiler of this structure is big, and fuel combustion is insufficient, and the thermal efficiency is low, the coal gas that produces above the combustion chamber and a large amount of combustible dust from above smoke exhaust pipe discharge out of the furnace, not only waste energy, also environment is polluted.

Summary of the invention:

The purpose of this utility model provides the energy-saving environment-friendly gasification boiler that a kind of fuel combustion is abundant, reduce environmental pollution, thermal efficiency height, energy savings, overcomes the deficiencies in the prior art.

Technical solution of the present utility model is: a kind of energy-conserving and environment-protective gasifying boiler, it comprises the flue of being made up of skin 1 and internal layer 23, it is characterized in that: the bottom of internal layer 2 is cone shape and is provided with ash port 15, in the outside of this cone flue 3, be provided with airduct 5, airduct 5 connection interfaces 11 and tuyere 6, interface 11 stretch out outer 1 the outside, and the inboard of internal layer 2 bottom cones is stretched in the termination of tuyere 6,15 places are provided with dust block board 8 at ash port, and dust block board 8 places on the slideway 7.

Be provided with upcast ventilation pipe 9 in the described flue 3, the interface 16 of upcast ventilation pipe 9 stretches out outer 1 the outside, upcast ventilation pipe 9 mouth 10 of giving a dinner for a visitor from afar, and tuyere 10 is towards stove hall inboard.

The utility model compared with prior art has following advantage: because this device is direct fuel place and top, combustion chamber air feed in the combustion chamber; the air quantity abundance; make fuel combustion abundant; the gas dust particle that produces when burning rises to stove one's parents Fang Shi and also can burn once more; fuel saving not only; also solved the problem of discharging coal gas and dust to atmosphere; when improving the thermal efficiency; protected environment again; because the internal layer bottom is taper; also solve fuel and when burning, produced the defect at dead angle, utilized this device can save the energy 30%.

Fig. 1 is the structural representation of the utility model specific embodiment;

Fig. 2 is the polycrystalline substance partial schematic sectional view of flue 3.

Fig. 3 is the cross-sectional schematic of overlooking shown in Figure 2;

Fig. 4 is the upcast ventilation pipe schematic diagram in the flue 3.

The specific embodiment

As shown in the figure: 1 is outer, and 2 is internal layer, and skin 1 and internal layer 2 are metallic plate and make, and forms a flue 3 between skin 1 and internal layer 2, is provided with the stove hall pipe 4 of horizontal direction in the inboard of internal layer 2, and stove hall pipe 4 is communicated with flue 3 inner chambers.Be provided with smoke exhaust pipe above it, the side, below is provided with fire door 13.Be connected to hot water outlet on outer 1 and cold water is answered back, hot water outlet and cold water are answered back by valve control device and are joined with thermic devices during work.Above-mentioned is the prior art part, no longer describes in detail.

The bottom of internal layer 2 is cone shape and is provided with ash port 15 in the center, in flue 3 inner chambers of the outside of this cone, be welded with bustlepipe 5, outer 1 the outside is stretched out in two terminations of airduct 5, one end is welded with interface 11, other end thread connection has nut stifled 12, the inboard, annulus place of airduct 5 is welded with equally distributed tuyere 6, and the termination of tuyere 6 puts in the inboard of internal layer 2 bottom cones.Be provided with an active catch hawk 8 at ash port 15 places, dust block board 8 places on the slideway 7, and slideway 7 is made and is welded on the base plate of flue 3 for the angle steel section bar.Fuel enters dust block board 8 tops, inner chamber place that just place cone in the stove from fire door 13, and the wind that blows into from tuyere 6 also just blows the position at the fuel place.Be connected with a cleanout door 14 at the bottom sides hinge, utilize hook-shaped instrument to move along slideway 7, reach the purpose of closing or open ash port 15 by the moving dust block board 8 of cleanout door 14 hooks.

Above-below direction is welded with a upcast ventilation pipe 9 in the described flue 3, and the interface 16 of upcast ventilation pipe 9 stretches out outer 1 the outside, and upcast ventilation pipe 9 connects down the tuyere of arranging 10, and tuyere 10 is towards stove hall inboard.

During work, interface 11,16 and blower conduits are joined.The direct air feed of the fuel of circular cone inner chamber by tuyere 6, sufficient combustion does not have the dead angle, after the coal gas that is produced in combustion process rises, because the effect of tuyere 10 can burn once more, unlikelyly directly discharges out of the furnace.As the needs deslagging, slidably dust block board 8 falls slag, closes dust block board 8 behind the deslagging again and gets final product.
