Description
Technical field:
The utility model relates to a kind of boiler, especially a kind of Zero-discharge energy-saving gasification boiler of energy-saving and environmental protection.
Background technology:
At present, existing miniature boiler structure constitutes water jacket between the two for being provided with body of heater and flue, water jacket connects hot water outlet and cold water is answered back, and is burner hearth in the flue, and burner hearth bottom is provided with dust block board, the dust block board below is an ash port, and flue taps into wind apparatus near dust block board.During use, be positioned at and produce the water heating of heat to water jacket after the fuel combustion on the dust block board, hot water is sent into through pipeline and use thermic devices, and heat radiation back cold water is back in the water jacket and is heated, and circulates repeatedly.The boiler power consumption of this structure is big, and fuel combustion is insufficient, and the thermal efficiency is low, and the coal gas of generation and a large amount of combustible dust discharge out of the furnace from smoke exhaust pipe, not only waste energy, and also environment are polluted.
Technology contents:
The utility model provides a kind of Zero-discharge energy-saving gasification boiler that discharged flue gas is fully burned in order to solve the existing in prior technology technical problem.
Technical solution of the present utility model is: a kind of Zero-discharge energy-saving gasification boiler, be provided with body of heater 1 and flue 2, constitute water jacket 20 between the two, it is characterized in that: body of heater 1 is for horizontal, the top of body of heater 1 is provided with time smoke pipe 8 that communicates with burner hearth 18, return smoke pipe 8 above be covered with and send smoke pipe road 6, the rear portion of body of heater to be provided with the smoke discharging pipe 7 that communicates with burner hearth 18, send 7 of smoke pipe road 6 and smoke discharging pipes to be connected by blower fan 11; Flue 2 bottoms are cone-shaped, are respectively equipped with bottom ventilation ducts 3 in the outside of above-mentioned cone water jacket 20, and bottom ventilation ducts 3 connects by pipe 4, is provided with the tuyere 5 that feeds in the burner hearth 18 on bottom ventilation ducts 3; In water jacket 20, also be provided with middle part ventilation duct 17, be connected to the tuyere 21 that feeds in the burner hearth 18 with middle part ventilation duct 17.
On described body of heater 1, be provided with the clear water dirt mouth 12 that communicates with water jacket 20 bottoms.
On the sidewall of described body of heater 1, be provided with the mechanical coal feeding hole 10 that communicates with burner hearth 18.
Be provided with delivery port 9 at the top of described body of heater 1, the water inlet 16 that is provided with in the bottom of body of heater 1, delivery port 9, water inlet 16 communicate with water jacket 20 respectively.
The present invention compared with prior art has following advantage: sufficient coal gas of unburned and dust are concentrated recovery, be passed into once more in the burner hearth, it is fully burnt, when having improved fuel availability, solved the pollution problem to environment of coal gas and dust again; This device is to blow simultaneously to burner hearth bottom and middle part, and the so material in the stove is burnt fast, has improved the thermal efficiency; And because the bottom of flue is cone shape, avoided fuel when burning, to produce the dead angle, prevented the waste of the energy.

The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: a kind of Zero-discharge energy-saving gasification boiler, be provided with body of heater 1 and flue 2, constitute water jacket 20 between the two, in the flue 2 is burner hearth 18, burner hearth 18 bottoms are provided with dust block board 19, dust block board 19 belows are ash port 22, ash port 22 has the slide rail 13 of slag drawer, the body of heater 1 corresponding with slide rail 13 is provided with slag-drip opening 14, and the top of slag-drip opening 14 is provided with manual coal feeding hole 15, it is characterized in that: body of heater 1 is for horizontal, the top of body of heater 1 is provided with a plurality of time smoke pipes 8 that communicate with burner hearth 18, return smoke pipe 8 above be covered with and send smoke pipe road 6, the rear portion of body of heater to be provided with the smoke discharging pipe 7 that communicates with burner hearth 18, send 7 of smoke pipe road 6 and smoke discharging pipes to be connected by blower fan 11; Flue 2 bottoms are cone-shaped, are respectively equipped with bottom ventilation ducts 3 in the outside of above-mentioned cone water jacket 20, and bottom ventilation ducts 3 connects by pipe 4, is provided with the tuyere 5 in a plurality of feeding burner hearths 18 on bottom ventilation ducts 3; In water jacket 20, also be provided with middle part ventilation duct 17, be connected to the tuyere 21 that feeds in the burner hearth 18 with middle part ventilation duct 17.Bottom ventilation ducts 3 and middle part ventilation duct 17 join with air blast respectively.
