Description
Technical Field
The invention relates to the field of incineration, in particular to an airtight device applied to an incineration grate furnace.
Background
The garbage incineration method has become one of the main methods for municipal waste treatment because of its remarkable reduction effect, land saving, elimination of various pathogens, conversion of toxic and harmful substances into harmless substances, and the like.
In the core equipment of the garbage incinerator, a fire grate is generally divided into three sections, namely a drying section, a combustion section and a burnout section, wherein each section of the fire grate moves through a driving device. In the burning process, a large amount of high-temperature harmful gas is generated.
Each section of fire grate is respectively provided with a driving sealing protection device, but the sealing material is lost due to long-time operation, so that the sealing protection effect is influenced to a certain extent, and the sealing material needs to be replaced periodically to ensure that the internal gas does not leak.
Disclosure of Invention
The invention aims to improve the operation condition of a waste incinerator grate, and provides an air-tight device applied to a waste incinerator grate. The specific technical scheme is as follows:
an air-tight device suitable for an incinerator grate furnace comprises an air blower, a pipeline, a metal hose, a flange assembly, a sealing ring, a bent pipe and a joint.
The flange assembly in the airtight device is divided into two parts which can be assembled and synthesized by bolts, and the installation and the disassembly are very convenient; meanwhile, the ventilation holes can be reserved, so that the air pipes and the bent pipes are completely sealed in a full-welding mode, the air leakage phenomenon can be avoided, and the air pipe sealing performance is ensured.
The flange component is provided with the positioning hole, and due to the high precision requirement, the flange component can be completely attached to the fire grate sealing box, so that the phenomenon of friction and abrasion with a fire grate driving rod in the operation engineering is prevented.
The flange component is internally provided with a clamping groove for mounting a sealing ring, the sealing ring is made of a material with high temperature resistance and low friction coefficient, and the leakage-proof effect is further achieved, so that the whole process forms a multiple sealing structure.
The model selection of the fan, the specification of the pipeline and the model of the metal hose are determined by calculating the air quantity and the flow rate of the pipeline, so that the stable pressure and the balanced air speed are ensured, and the maximum effect of the air-tight device is achieved.
The positive pressure blowing is forcibly carried out on the fire grate sealing box through the air-tight device, so that the internal gas stays in the incinerator all the time, and the gas is prevented from being slowly leaked out in the movement process of the fire grate driving rod.
The invention has the beneficial effects that:
the airtight device of the incineration grate furnace can effectively prevent the phenomena of flue gas, dust raising and furnace dust leakage through the movable area of the driving push rod. Simultaneously to the high temperature air current that burns burning furnace and produce, through air cooling, can play good cooling effect, increase the life of seal box and inside spare part, the spare part replacement rate that significantly reduces improves and burns burning furnace steady operation duration, reduces the maintenance work in later stage, reduces the operation cost effectively.

Detailed description of the invention
As shown in fig. 1 to 4, the airtight device suitable for an incinerator includes a blower 105, a duct 106, a first metal hose 107, a second metal hose 109, a flange assembly 104, a gasket 208, an elbow 202, and a joint 108. The flange assembly 104 is designed with a flange plate 201, an elbow 202, a positioning rib plate 203, a fixing nut 204, a connecting bolt 205, a vent hole 206, a clamping groove 207 and a sealing ring 208.
The flange plate 201 is divided into two parts, and is assembled in a butt joint mode through a fixing nut 204 and a connecting bolt 205; a clamping groove 207 is formed in the flange plate 201 and used for installing a sealing ring 208; a vent hole 206 is reserved in the flange plate 201, and the bent pipe 202 is welded with the reserved vent hole 206; and welding the positioning rib plate 203 on the flange plate 201.
After the sealing ring 208 is sleeved on the grate driving rod 101 in a reserved position, the grate driving rod 101 is assembled and connected with the grate driving beam 102, and the grate sealing box 103 is arranged on the grate driving rod 101.
The bent pipe 202 and the vent holes 206 on the flange plate 201 are fully welded and completely sealed, so that the phenomena of air leakage and air leakage are avoided, and the sealing performance of the air pipe is ensured.
Because the flange 201 is designed in half and half, the flange needs to be preassembled outside the grate driving rod 101, and then the sealing ring 208 is pressed into the clamping groove 207 of the flange 201, so that the sealing effect is further achieved.
The flange plate 104 is connected with the sealing box 103 by utilizing the positioning rib plate 203, and the positioning rib plate 203 and the sealing box 103 can be completely attached and assembled due to high requirements on the processing precision, so that the loss caused by friction of parts in the operation process is effectively avoided. And then the flange plate 201 is assembled by the connecting bolts 205 and the fixing nuts 204 to form the flange assembly 104.
After the blower 105, the duct 106, and the first metal hose 107 are connected to each other, the second metal hose 109 is connected to the elbow 202 through the joint 108. And after all the connecting processes are finished, ensuring the complete sealing among the parts through an airtight test.
And finally, starting the blower 105, filling the pipeline 106 with air and maintaining the pressure through the first metal hose 107, and forcibly performing positive-pressure air supply cooling on the fire grate sealing box 103 through the second metal hose 109 and the flange assembly 104 to form stable output.
The measured data are as follows:
