Technical Field
The invention belongs to the field of outer walls of garbage incinerators, and particularly relates to a garbage incinerator outer wall with good heat insulation performance and long service life.
Background
The garbage incinerator is an apparatus for incinerating garbage, which can generate a large amount of heat energy by incinerating garbage and effectively output a part of the heat energy for power generation or domestic heating. The hearth wall of the garbage incinerator is constructed by an arch protection wall, the arch protection wall consists of an arch protection inner wall contacted with the hearth and an arch protection outer wall contacted with the external space, and the arch protection inner wall and the arch protection outer wall are generally connected through grabbing nails. The heat insulation performance of the arch protection outer wall is directly related to the heat insulation effect of the garbage incinerator, the heat insulation performance of the arch protection outer wall of the existing garbage incinerator is poor, so that a large amount of heat generated by garbage incineration is emitted to a workshop, the temperature of the workshop becomes high, the environment of the workshop becomes poor, and the heat is emitted to the workshop to greatly reduce the heat efficiency of the garbage incinerator (the heat efficiency refers to the ratio of the heat energy effectively output by the garbage incinerator to the total heat energy generated by garbage incineration). The working environment of the arch protection outer wall is bad and is in a high-temperature environment for a long time, the grabbing nails are easy to be corroded and broken by high-temperature smoke penetrating into the arch protection inner wall, the arch protection outer wall is easy to fall off, and the service life of the garbage incinerator is short. Because the heating degree of the arch protection inner wall is different from that of the arch protection outer wall, the temperature rising amplitude of the arch protection inner wall is different from that of the arch protection outer wall, the thermal deformation amplitude of the arch protection inner wall is different from that of the arch protection outer wall, stress accumulation is easy to occur between the arch protection inner wall and the arch protection outer wall, the stress is basically born by the grabbing nails, the grabbing nails are easy to break, the arch protection outer wall falls off, and the service life of the garbage incinerator is also short.
Therefore, the garbage incinerator manufactured by adopting the existing arch protection outer wall has the defects of poor workshop environment, low heat efficiency and short service life.

In the garbage incinerator outer wall with good heat insulation performance and long service life, the through hole is formed in the inner layer plate, the cylindrical rubber pad is arranged in the through hole, the annular groove is formed in the peripheral surface of the rubber pad, the inner layer plate is connected with the rubber pad through the annular groove, the screw hole is formed in the axial direction of the rubber pad, and the screw penetrates through the screw hole and then is connected with the ceramic tile.
In the garbage incinerator outer wall with good heat insulation performance and long service life, the first steel bars, the second steel bars and the third steel bars are I-shaped steel.
In the outer wall of the garbage incinerator with good heat insulation performance and long service life, the air duct and the water channel are repeatedly bent channels, and the water inlet is lower than the water outlet.
Compared with the prior art, the air duct is arranged between the inner layer plate and the middle layer plate, so that a part of heat can be recovered, the part of heat is utilized to preheat air and input the air into the hearth of the garbage incinerator, the garbage is combusted for supporting combustion, the degree of degradation of workshop environment caused by heat loss is reduced through the recovery and utilization of the heat, and the thermal efficiency of the garbage incinerator is improved; the polyurethane foam between the middle layer plate and the outer layer plate has good heat insulation effect, and the heat is kept in the garbage incinerator by utilizing the good heat insulation effect of the polyurethane foam, so that the degradation degree of the workshop environment caused by heat loss is further reduced, and the heat efficiency of the garbage incinerator is improved; the water channel between the outer layer plate and the surface plate can basically absorb the residual heat, the heat emitted to the workshop through the surface plate is little, the temperature change of the workshop is small, and the workshop environment is not deteriorated; the invention obtains good heat insulation effect by sequentially recycling, isolating and absorbing the heat, and has small heat loss to workshops, so that the garbage incinerator manufactured by the invention can not degrade the workshop environment, and the heat loss is small, thereby avoiding the great reduction of the heat efficiency of the garbage incinerator. Because the water inlet of the water channel is lower than the water outlet, and the density of air is lower than that of water, the air in the water channel is easy to be discharged along with water flow, the contact area of water and the water channel is large, the heat absorption efficiency is high, the small temperature change of a workshop is further ensured, and the workshop environment cannot be worsened. The screw is equivalent to a grabbing nail, the screw is not directly connected with the arch protection inner wall, the screw is connected with the arch protection inner wall through the ceramic tile, and the screw is buried in the ceramic tile with compact structure and is not easy to be corroded by high-temperature smoke, so that the connection between the screw and the arch protection inner wall is firm, the falling phenomenon is not easy to occur, and the garbage incinerator manufactured by the invention has long service life. The pile stress between the invention and the arch protection inner wall firstly acts on the rubber pad and then acts on the screw, and the rubber pad has a buffer function, so that the stress on the screw is small and is not easy to break, and the service life of the garbage incinerator manufactured by the invention is also ensured to be long. Therefore, the garbage incinerator manufactured by the method has the advantages of no degradation of workshop environment, high heat efficiency and long service life.
