The furnace wall cooling device comprises a thermal insulation furnace chamber and is characterized in that the peripheries of the furnace walls on two sides of the thermal insulation chamber are closed, the central area at least comprises a middle air gap layer, an inner refractory brick layer and an outer thermal insulation brick layer, and the middle air gap layer is communicated with an air cooling wall air inlet and an air cooling wall air outlet respectively.
Description
Technical field
The utility model relates to the technical field of structures of boiler, is specially a kind of furnace wall cooling device of garbage burning boiler.
Background technology
Slagging scorification is the at high temperature melting of inorganic matter in rubbish and the object that generates, and melting is adhered to temperature about 1000～1100 ℃.Due to domestic house refuse, there is the fuel characteristics such as high-moisture, low heat value, complicated component, for assurance garbage energy is caught fire well, burns, burnt.We,, when design incinerator, generally adopt adiabatic furnace.But once refuse thermal value rises, will cause localized hyperthermia's burning and coking is attached on furnace wall and increases, this phenomenon can shorten refractory brick life-span, reduce the ability of waste incineration.
Summary of the invention
For existing above-mentioned defect, the utility model provides a kind of furnace wall cooling device of garbage burning boiler, and it makes the surface temperature of refractory brick be cooled to 700～800 ℃, can effectively prevent slagging scorification generation, adhere to and grow up, guarantee the life-span of refractory brick, improved the ability of waste incineration.
A kind of furnace wall cooling device of garbage burning boiler, its technical scheme is such: it comprises adiabatic furnace, it is characterized in that: the surrounding sealing of the both sides furnace wall of described adiabatic furnace, central area at least comprise intermediate air gap layer, inner side fire brick layer, outside insulation brick layer, and described intermediate air gap layer is communicated with respectively air cooling wall air inlet, air cooling wall air outlet.
It is further characterized in that:
The described air cooling wall air inlet of both sides furnace wall connects respectively the air outlet of burner hearth cooling blower by pipeline;
The air outlet of described burner hearth cooling blower is respectively arranged with air register to the pipeline of air cooling wall air inlet;
The described air cooling wall air outlet of both sides burner hearth connects respectively the air inlet of the cooling air-introduced machine of burner hearth by pipeline;
The air outlet of the cooling air-introduced machine of described burner hearth is by the external wind inlet scoop of pipeline.
Adopt after structure of the present utility model, by air cooling wall air inlet to the air of sending into normal temperature in the air gap layer of the central area of the both sides furnace wall of adiabatic furnace, utilize heat exchange principle, make the surface temperature of refractory brick be cooled to 700～800 ℃, can effectively prevent slagging scorification generation, adhere to and grow up, guaranteed the life-span of refractory brick, improve the ability of waste incineration, thereby and regulated intake to adapt to the different refuse thermal value of burning by the air register on air cooling wall blast pipe.

The specific embodiment
A kind of furnace wall cooling device of garbage burning boiler, see Fig. 1～Fig. 3: it comprises adiabatic furnace 1, the surrounding sealing of the both sides furnace wall 2 of adiabatic furnace, central area at least comprise intermediate air gap layer 3, inner side fire brick layer 4, outside insulation brick layer 5, and intermediate air gap layer 3 is communicated with respectively air cooling wall air inlet 6, air cooling wall air outlet 7.The air cooling wall air inlet 6 of both sides furnace wall 2 connects respectively the air outlet of burner hearth cooling blower 8 by pipeline; The air outlet of burner hearth cooling blower 8 is respectively arranged with air register 9 to the pipeline of air cooling wall air inlet 6; The air cooling wall air outlet 7 of both sides burner hearth 2 connects respectively the air inlet of the cooling air-introduced machine 10 of burner hearth by pipeline; The air outlet of the cooling air-introduced machine 10 of burner hearth is by the external wind inlet scoop of pipeline.In figure, 11 is that compensator, 12 is that normally open valve door, 13 is muffler.
Its operation principle is as follows: the air of normal temperature is delivered to respectively the described air cooling wall air inlet 6 of both sides furnace wall 2 by pipeline by burner hearth cooling blower 8, sneak in intermediate air gap layer 3, utilize heat exchange principle, normal temperature air makes the surface temperature of inner side fire brick layer 4 be cooled to 700～800 ℃, simultaneously, also can be the air heat of normal temperature, then under the attraction of the cooling air-introduced machine 10 of burner hearth, heated air is inhaled into wind inlet scoop one time, participate in the burning in adiabatic furnace, improved energy utilization rate.
