Abstract

The utility model relates to a high-efficient energy-saving dust removing and smoke removing boiler, which belongs to the technical field of the production of a combustion device. The utility model overcomes the defect that the existing boiler has insufficient combustion, environmental pollution caused by smoke and dust to be discharged and low heat utilization rate. The utility model is provided with an auxiliary combustion dust removing chamber (2) and an energy-saving dust removing chamber (5), and the auxiliary combustion dust removing chamber (2), the energy-saving dust removing chamber (5), a combustion chamber (1) and a water pipe chamber (4) are formed into integration and are communicated with each other through a passage (9). The utility model is a high-efficient energy-saving dust removing and smoke removing boiler having high thermal efficiency, sufficient combustion and good smoke removing and dust removing effect.

Description

Energy-efficient dedusting smoke-removing boiler

The utility model relates to a kind of energy-efficient dedusting smoke-removing boiler, and it belongs to the combustion apparatus production technical field.

Double grate boiler of the prior art, have little cigarette hole in burner hearth one side, lead to dividing plate top, mainly carry out heat exchange by upper pipe by a smoke pipe, the pyrotechnics temperature influence that overflows of burner hearth is bigger so, and insufficient soot emissions contaminated environment and heat utilization efficiency of causing thus of burning is low.

The purpose of this utility model be to avoid the deficiencies in the prior art and designed a kind of thermal efficiency height,, sufficient combustion, energy-efficient dedusting smoke-removing boiler that smoke medicining dust-removing effect is good.

The utility model comprises the combustion chamber, the water pipe chamber, water pipe, lower fire grating, outlet pipe, overflow pipe, blast pipe, blow-off pipe, fire door, cleanout door, shoot door, chimney and water level meter, water pipe furnace grate, this boiler is provided with secondary burning dirt pocket and energy-saving dedusting chamber, they and combustion chamber, the water pipe chamber constitutes one, junction between boiler jacket and chamber and the chamber is an interlayer, the combustion chamber communicates with secondary burning dirt pocket by passage, the water pipe chamber is passed through passage and energy-saving dedusting chamber separately respectively, secondary burning dirt pocket communicates, secondary burning dirt pocket top is established water pipe and is horizontally placed on therebetween, the below of its underpart and energy-saving dedusting chamber is provided with dust removing door separately, and chimney places the dust removing door top of energy-saving dedusting chamber.Be provided with thermal insulation layer above lower fire grating, thermal insulation layer is that refractory material constitutes.The water pipe chamber is established the interlayer baffle plate and is placed therebetween.

Compare in the energy-efficient dedusting smoke-removing boiler of making as stated above and the prior art and have following advantage:

1, thermal efficiency height, the thermal insulation layer of fire grate top is because its insulation effect, improved furnace temperature, the fuel gas of underflow is fully burnt, the fire cigarette enters secondary burning dirt pocket and water pipe chamber by passage, and flow velocity can make slowly that fuel gas burns fully, water pipe fully absorbs heat, and exhaust gas temperature is reduced between 160-180 ℃, the thermal efficiency reaches 80%, and is more energy-conservation more than 50% than routine.

2, smoke medicining dust-removing effect is good, and gas fuel burning is abundant, and flow velocity is slow, and the sedimentation flue dust that stops of the tube wall by four chambers, interlayer, baffle plate reaches this purpose.

3, cost is low, the thermal efficiency is high, and pair burning dirt pocket and energy-saving dedusting chamber that the utility model is set up can make the stove outer covering of own and 1/2 be heated, and can dwindle the height of boiler and reduce internal pipeline, do not need to install cleaner again.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model one embodiment.

Energy-efficient dedusting smoke-removing boiler, it comprises combustion chamber 1, water pipe chamber 4, water pipe 9, lower fire grating 15, outlet pipe 13, overflow pipe 12, blast pipe 18, blow-off pipe 14, fire door 20, cleanout door 16, shoot door 17, chimney 11 and water level meter 3, water pipe furnace grate 19, secondary burning dirt pocket 2 and energy-saving dedusting chamber 5 and combustion chamber 1, water pipe chamber 4 constitutes one, boiler jacket, junction between chamber and the chamber is an interlayer, combustion chamber 1 communicates with secondary burning dirt pocket 2 by passage 7, water pipe chamber 4 is passed through passage 7 and energy-saving dedusting chamber 5 separately respectively, secondary burning dirt pocket 2 communicates, secondary burning dirt pocket 2 tops are established water pipe 9 and are horizontally placed on therebetween, the below of secondary burning dirt pocket 2 bottoms and energy-saving dedusting chamber 5 is provided with dust removing door 8 separately, chimney 11 places dust removing door 8 tops of energy-saving dedusting chamber 5, lower fire grating 15 tops are provided with thermal insulation layer 6, thermal insulation layer 6 is a refractory brick, and water pipe chamber 4 is established interlayer plate washer 10 and placed therebetween.
