In order to solve the problems existing in background technology, the utility model is adopted the following technical scheme that including furnace body, row Chimney, combustion barrel and burner, furnace body are vertical cylinder, and furnace body top cover middle position stands smoke exhaust barrel, bottom in furnace body Equipped with combustion barrel, combustion barrel one end is placed in outside furnace body and connect with burner, and the furnace body internal upper part is equipped with water inlet pipe, water inlet pipe Bottom end is equipped with several spray throwers；The burning tube end plate is skewed, combustion barrel top middle installation flue, smoke Cylinder outlet flue is connect with flue gas coil pipe bottom end smoke inlet, and flue gas coil pipe is coiled in the inner cavity of furnace body, the top smoke of flue gas coil pipe Mouth is connect with smoke exhaust barrel bottom smoke inlet, and the combustion barrel is placed in one end outside furnace body and is equipped with feed hopper, is equipped in feed hopper With agitating shaft and stirring blade of different sizes, the top of agitating shaft are connect with driving motor output shaft, and feed hopper bottom end is equipped with Stock guide, stock guide is oblique and stretches to burning tube end plate, and biomass granule fuel is filled in feed hopper；In the furnace body Crossbearer water filtration plate passes through flue gas coil pipe on water filtration plate, is equipped with gap below water filtration plate, gap is located at sidewall of the furnace body On, another sidewall bottom of furnace body is equipped with outlet pipe.

It is equipped with smoke filtration plate in the smoke exhaust barrel, places metal packing on smoke filtration plate.

The combustion barrel other end has the sight fire visor extended to outside furnace body.

The utility model has the beneficial effects that structure is simple, securely and reliably,

1) biomass granule fuel is used, has achieved the purpose that the flue gas generated when burning does not pollute the environment；

2) smoke filtration plate is used, so that the flue gas of discharge will not pollute air；

3) stirring blade is used, prevents fuel from blocking feed hopper, duration in combustion barrel is influenced and burns；

4) it is exchanged heat using flue gas coil pipe to water, not only ensure that the thermal efficiency of heat exchange, but also dirt will not be caused to water Dye；

5) water filtration plate is used, the water after heat exchanging is filtered, trusts people and use water.

Detailed description of the invention:

Fig. 1 is the utility model structure diagram.

Specific embodiment:

Referring to Fig.1, the utility model specifically uses and mode is implemented as follows: including furnace body 1, smoke exhaust barrel 17, combustion barrel 4 and combustion Burner 8, furnace body 1 are vertical cylinder, and 1 top cover middle position of furnace body stands smoke exhaust barrel 17, and bottom is equipped with combustion barrel in furnace body 1 4,4 one end of combustion barrel is placed in outside furnace body 1 and connect with burner 8, and 1 internal upper part of furnace body is equipped with water inlet pipe 14, water inlet pipe 14 Bottom end is equipped with several spray throwers 15；4 bottom plate of combustion barrel is skewed, 4 top middle of combustion barrel installation flue 3,3 outlet flue of flue is connect with 13 bottom end smoke inlet of flue gas coil pipe, and flue gas coil pipe 13 is coiled in the inner cavity of furnace body 1, flue gas 13 top outlet flue of coil pipe is connect with 17 bottom smoke inlet of smoke exhaust barrel, the combustion barrel 4 be placed in one end outside furnace body 1 be equipped with into Hopper 11, feed hopper 11 is interior to be equipped with stirring blade 10 with agitating shaft and of different sizes, and the top of agitating shaft and driving motor 9 are defeated Axis connection out, 11 bottom end of feed hopper are equipped with stock guide 7, and stock guide 7 is oblique and stretches to 4 bottom plate of combustion barrel, in feed hopper 11 Fill biomass granule fuel；Crossbearer water filtration plate 2 in the furnace body 1 passes through flue gas coil pipe 13, water mistake on water filtration plate 2 Gap 12 is equipped with below filter plate 2, gap 12 is located on 1 side wall of furnace body, and another sidewall bottom of furnace body 1 is equipped with outlet pipe 6.Institute It is equipped with smoke filtration plate 16 in the smoke exhaust barrel 17 stated, places metal packing on smoke filtration plate 16.4 other end of combustion barrel There is the sight fire visor 5 extended to outside furnace body 1.

This boiler when in use, fuel is filled into feed hopper 11, and fuel is biomass granule fuel, biological particles combustion Material is the Novel clean-fuel that can directly burn, its not sulfur-bearing phosphorus, does not corrode boiler, and when burning does not produce sulfur dioxide and five oxidations The atmosphere pollutions such as phosphorus, not can cause environmental pollution, it is that we create the important channel of conservation-minded society, starting driving electricity Machine 9, driving motor 9 drives agitating shaft rotation, and then the stirring blade 10 on agitating shaft moves in a circle therewith, on agitating shaft Stirring blade 10 is of different sizes, and the stirring blade model positioned at 11 bottom of feed hopper is smaller, and stirring blade 10 enters on fuel side The stirring of 4 side of combustion barrel prevents the discharging of granular fuel blocking 11 bottom of feed hopper, influences duration in combustion barrel 4 and burns, fuel It is dispersed in 4 bottom of combustion barrel by skewed stock guide 7 adequately to be burnt, the hot fume that when burning generates passes through smoke Cylinder 3 enters in flue gas coil pipe 13, and flue gas coil pipe 13 is coiled in furnace body 1, and water is sprayed at by water inlet pipe 14 and spray thrower 15 In furnace body 1, water carries out heat exchange by flue gas coil pipe 13, and water carries out contaminant filter by water filtration plate 2 after heat exchange, is needing It when with water, is discharged by outlet pipe 6, water exchanges heat by flue gas coil pipe 13, will not take away as in metal packing Metal impurities, and also pass through water filtration plate 2, further remove the impurity in water, trust people and use water.

Hot fume after heat exchange is discharged by smoke exhaust barrel 17, first passes around smoke filtration plate 16 to cigarette in hot fume discharge The filtering that gas carries out the impurity such as dust particles has reached energy-saving and environment-friendly purpose so that the flue gas of discharge does not pollute the environment.

It sees fiery visor 5 to be convenient for checking the combustion case of combustion barrel 4, to increase and decrease the fuel in combustion barrel 4.

In conclusion to set burner directly-heated total exchange hot water boiler structure simple for background, securely and reliably, using biomass Grain fuel has achieved the purpose that the flue gas generated when burning does not pollute the environment；Using smoke filtration plate 16, so that the cigarette of discharge Gas will not pollute air；It using stirring blade 10, prevents fuel from blocking feed hopper 11, influences duration in combustion barrel 4 and burn；It adopts It is exchanged heat with flue gas coil pipe 13 to water, not only ensure that the thermal efficiency of heat exchange, but also will not pollute to water；Using water mistake Filter plate 2, the water after heat exchanging are filtered, trust people and use water.
