Abstract

The present invention discloses a boiler, particularly an energy-saving environment-protecting gasifying boiler which comprises a boiler furnace [3] composed of an outer layer [1] and an inner layer [2]. The present invention is characterized in that the bottom of the inner layer [2] forms a cone shape and is provided with an ash filling mouth [15], and a wind pipe connected with an interface [11] and an air nozzle [6] is arranged in the boiler furnace [3] on the outer side of a cone; the interface [11] extends out of the outer side of the outer layer [1], and the end head of the air nozzle [6] extends into the inner side of the cone on the lower part of the inside layer [2]; the ash filling mouth [15] point is provided with an ash blocking plate [8] which is positioned on a slide way [7]. Because the present invention supplies wind directly towards a fuel place in a combustion chamber and the upper part of the combustion chamber, the fuel is thoroughly combusted and gas and dust particles generated during combustion can carry out secondary combustion when ascending to the upper part of a boiler chamber. In this way, the present invention has the advantages of saving fuel, solving the problem of the exhaustion of gas and dust towards atmosphere, improving thermal efficiency and protecting environment, and because the bottom of the inner layer forms a cone shape, the present invention also solves the defect of the generation of dead corner during the combustion of the fuel and can save energy by 30 percent.

Description

Energy-saving environment-friendly gasification boiler

Technical field:

The present invention 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 furnace tube above the combustion chamber is communicated with flue, the vertical setting that furnace tube 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 furnace tube, 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 invention is to provide the energy-saving environment-friendly gasification boiler that a kind of fuel combustion is abundant, reduce environmental pollution, thermal efficiency height, energy savings, overcome the deficiencies in the prior art.

Technical solution of the present invention is: a kind of energy-conserving and environment-protective gasifying boiler, it comprises the flue of being made up of outer and internal layer, it is characterized in that: the bottom of internal layer is cone shape and is provided with ash port, in the flue of the outside of this cone, be provided with airduct, airduct connection interface and following tuyere, interface stretches out the outer field outside, and the inboard of internal layer bottom cone is stretched in the termination of following tuyere, the place is provided with dust block board at ash port, and dust block board places on the slideway.

Be provided with upcast ventilation pipe in the described flue, the interface of upcast ventilation pipe stretches out the outer field outside, and upcast ventilation pipe connects the crosswind mouth, and the crosswind mouth is towards the burner hearth inboard.

The present invention 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 in when burning also can burn when rising to above the burner hearth 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%.

Description of drawings:

Fig. 1 is the structural representation of the specific embodiment of the invention;

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 furnace tube 4 of horizontal direction in the inboard of internal layer 2, and furnace tube 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 down, and the termination of following 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 descends tuyere 6 to blow into certainly 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 crosswind mouth of arranging 10, and crosswind mouth 10 is towards the burner hearth inboard.

During work, interface 11,16 and blower conduits are joined.The fuel of circular cone inner chamber is by the following direct air feed of tuyere 6, and sufficient combustion does not have the dead angle, after the coal gas that is produced in combustion process rises, because the effect of crosswind mouth 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.
