Description

CFBB ash exhauster

Technical field

This utility model belongs to boiler technology field, is specifically related to a kind of CFBB ash exhauster.

Background technology

Development along with society, daily life, the operation of factory all be unable to do without electric energy, at present, the mode of generating has thermal power generation, wind-power electricity generation, hydroelectric generation, nuclear energy power generation and geothermal power generation, wherein significant fraction uses thermal power generation, and thermal power generation system includes combustion system (with boiler as core), needs consumption of fossil fuels, and Fossil fuel can produce carbon dioxide etc. and pollute the gas of environment after being generally non-renewable energy resources, and burning.

Now, chicken farm in all parts of the country is a lot, wherein there is the most large-scale chicken farm, these chicken farms can produce substantial amounts of chicken manure every day, these chicken manures are only made into fertilizer on a small quantity, major part does not the most process, and is stacked on together or fills, and water and air all can be caused serious pollution by accumulation and landfill.Therefore, people, by research, generate electricity as fuel with chicken manure, solve chicken manure pollution on the environment, it is achieved that the sustainable development of the energy, and use chicken manure to replace the traditional fuels such as coal, also will not produce carbon dioxide etc. and pollute the gas of environment.But, the flying dust viscosity produced after burning due to chicken manure is big, easily sticks on convection bank, superheater, economizer and pocket preheater, causes dust stratification serious so that heat transfer efficiency is low, affect boiler operatiopn.The circulating fluidized bed boiler of Patent No. CN104315505A, arranges steam sootblower on the top of back-end ductwork, for the dust cleaned in flue on equipment, but, chicken manure viscosity is relatively big, uses the steam sootblower can not dust on removing equipment.Therefore remaining a need for manually being purged, but carry out ashman after blowing out when making, owing to the ash quantity got off clearly is big, and need to be transported to furnace bottom, so the labor intensity of workman is big, the time of cost is many, and it is the most dangerous to operate.

Summary of the invention

The purpose of this utility model is to provide a kind of CFBB ash exhauster time-consuming, that reduce the labor intensity of workman and safety the most time-consuming but also reduces the labor intensity of workman, improves the safety of workman's work.

This utility model provides a kind of CFBB ash exhauster, including: body of heater 101, separator 102, material returning device 103, it is arranged on the convection bank 106 that vertical flue 104 is interior and is sequentially connected with from top to bottom, high temperature superheater 107, low temperature superheater 108, high-temperature economizer 109, middle temperature economizer 110, low-level (stack-gas) economizer 111, primary air preheater 112 and auxiliary air preheater 113, also include ash discharge unit, ash discharge unit comprises: ash discharge house steward 21, and at least one the ash discharge arm 22 being connected with ash discharge house steward 21, flue 104 is provided with and ash discharge arm 22 manhole 105 one to one, manhole 105 is positioned at sustained height with corresponding ash discharge arm 22 mouth of pipe.

CFBB ash exhauster of the present utility model can also make further improvements restriction, and wherein, the lower wall of ash discharge arm 22 is diagonally downward.Conveniently pour ash discharge arm 22 dust into be slipped in ash discharge house steward 21.

CFBB ash exhauster of the present utility model can also make further improvements restriction, and CFBB ash exhauster also includes the cleaner unit 114 being connected with the bottom of flue 104 and the air-introduced machine 115 being connected with cleaner unit 114.For the flue gas of flue is carried out dedusting, it is to avoid pollute environment.

CFBB ash exhauster involved by this utility model, because the sidewall of flue arranges manhole, manhole is corresponding with ash discharge arm, and it being positioned at sustained height, ash discharge arm is connected with ash discharge house steward, so clearing up equipment in flue is that dust can pour ash discharge arm into by manhole, and then it is slipped to bottom ash discharge house steward, avoid and manually frequently carry dust, therefore, CFBB ash exhauster of the present utility model up and down.

Accompanying drawing explanation

Fig. 1 is the structural representation of CFBB ash exhauster in embodiment of the present utility model.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reaching purpose and be easy to understand with effect, following example combine accompanying drawing and are specifically addressed CFBB ash exhauster of the present utility model.

As it is shown in figure 1, CFBB ash exhauster comprises: body of heater 101, separator 102, material returning device 103, flue 104, convection bank 106, high temperature superheater 107, low temperature superheater 108, high-temperature economizer 109, middle temperature economizer 110, low-level (stack-gas) economizer 111, primary air preheater 112, auxiliary air preheater 113, cleaner unit 114, air-introduced machine 115, chimney 116 and deashing unit.

The top of body of heater 101 is connected with the air inlet of separator 102, and the discharging opening of separator 102 is connected with material returning device 103, and material returning device 103 is connected with the bottom of body of heater 101.The air outlet of separator 102 is connected with the top of flue 104.

Convection bank 106, high temperature superheater 107, low temperature superheater 108, high-temperature economizer 109, middle temperature economizer 110, low-level (stack-gas) economizer 111, primary air preheater 112 and auxiliary air preheater 113 are along the direction of flue gas flow direction, it is arranged on the most from top to bottom in flue 104, and is sequentially connected with.The bottom of flue 104 is connected with cleaner unit 114, and cleaner unit 114 is connected with air-introduced machine 115, for flue gas is carried out dedusting, it is to avoid smoke pollution environment, air-introduced machine 115 is connected with chimney 116, and the clean gas after dedusting is discharged from chimney 116.

The sidewall of flue 104 arranges at least one manhole 105, and ash discharge unit comprises ash discharge house steward 21, at least one ash discharge arm 22 and valve 23.In the present embodiment, the sidewall of flue 104 is provided with four manholes 105, four ash discharge arms 22.Valve 23 is arranged on the bottom of ash discharge house steward 21, for controlling the ash discharge amount of ash discharge house steward 21.Four ash discharge arms 22 are connected with ash discharge house steward 21 respectively, four ash discharge arms 22 respectively with four manhole 105 one_to_one corresponding, and each ash discharge arm 22 is positioned at sustained height with corresponding manhole 105.Therefore, after workman has cleared up the dust on equipment, by nearest manhole 105, dust can be poured in corresponding ash discharge arm 22, thus it is the most upper and lower to avoid workman, the most time-consuming but also reduce labor intensity, also improve the safety of workman's work simultaneously.Diagonally downward, therefore, the dust pouring ash discharge arm 22 into can be slipped to the bottom of ash discharge house steward 21 to the lower wall of each ash discharge arm 22 automatically.

Manhole 105 the position of flue sidewall should according to flue 104 in the situation of equipment be configured so that all have manhole near each device height.In the present embodiment, four manholes 105 are separately positioned on the height corresponding with high temperature superheater 107, high-temperature economizer 109, middle temperature economizer 110 and primary air preheater 112.
