Abstract
The invention provides a cooling device for furnace walls of a waste incineration boiler. By the cooling device, the surface temperature of refractory bricks decreases to range from 700 DEG C to 800 DEG C, generation, adhesion and growing of slag can be effectively prevented, the service life of the refractory bricks is guaranteed, and the capacity of waste incineration is improved. The cooling device comprises a heat insulation hearth, and is characterized in that the peripheries of the furnace walls of the two sides of the hearth are sealed, the center area of each furnace wall at least comprises a middle air interval layer, an inner side refractory brick layer and an outer side heat insulation brick layer, and each middle air interval layer is communicated with an air inlet of an air cooling wall and an air outlet of the air cooling wall respectively.
Description
Technical field
The present invention relates to the technical field of structures of boiler, be 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 invention provides a kind of furnace wall cooling device of garbage burning boiler, 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 invention, 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, guarantee the life-span of refractory brick, improved 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.
