Description
Technical Field
The utility model relates to a msw incineration equipment field, concretely relates to special wall case of waste incinerator soot blower.
Background
After the waste incineration waste heat boiler is positioned in the combustion chamber, the temperature of the combustion chamber can reach over 1000 ℃ after the waste is combusted, smoke is released and absorbed through three vertical flues generally and then enters a horizontal flue, and the heat of the smoke is further absorbed. However, as the waste incineration medium is complex in structure, the detonation phenomenon is easy to occur in the actual operation process, so that the boiler designed by negative pressure originally generates micro-positive pressure, and the smoke is easy to leak. Under the condition, the flue gas can enter the interior of the soot blower body along the gun barrel and the wall box of the soot blower, and acidic substances generated after the flue gas with high chlorine and high sulfur content is cooled are very easy to corrode the soot blower, so that the service life of the soot blower is influenced. Meanwhile, the leakage of the flue gas is not beneficial to the relevant standard requirements of safe production. In order to eliminate the influence of the micro-positive pressure on the soot blower, a soot blower wall box device used for the micro-positive pressure situation of the garbage furnace needs to be designed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention will be combined to clearly and completely describe the technical solutions in the embodiments of the present invention.
In the first embodiment, as shown in fig. 1 to 2, the wall box dedicated for the soot blower of the garbage incinerator comprises a box body 1, an air vent 2 is formed in an end surface of the box body 1, the box body 1 is fixedly sleeved on a surface of a gun tube 3, a nozzle 4 is formed in the surface of the gun tube 3, a frame 5 is sleeved outside the nozzle 4, a first stagnant flow pore plate 6 and a second stagnant flow pore plate 7 are fixedly clamped on two sides of an inner frame 5 of the box body 1 respectively, and the second stagnant flow pore plate 7 is three-layered. The series connection of the three stagnant flow pore plates can generate larger local resistance, and the smoke is more effectively prevented from leaking.
The working principle is as follows: when the soot blower does not operate, the flue gas can not enter the gun barrel, a plurality of stagnant flow pore plates are arranged at the contact part of the wall box and the atmosphere and the contact part of the wall box and the interior of the boiler, and the flue gas is effectively prevented from flowing to the atmosphere through the local resistance of the stagnant flow pore plates. Meanwhile, the first and second orifice plates 6 and 7 are in contact with the upper surface of the lance tube 3 of the soot blower, so that the accumulated soot attached to the surface of the lance tube 3 during soot blowing of the lance tube 3 can be effectively removed.
In this embodiment, the end face of the box body 1 is fixedly mounted on the supporting and hanging plate 8 through a countersunk bolt, and the supporting and hanging plate 8 is fixedly mounted on the boiler through a supporting and hanging device. The box body 1 is fixedly arranged at the end part of the boiler through the supporting and hanging plate 8, and the device is installed by adopting flexible connection, so that on-site replacement and maintenance are facilitated.
And flexible positioning rings 10 are arranged between the second stagnation orifice plates 7 at intervals. The flexible positioning ring 10 is flexibly connected with the second stagnant flow pore plate 7, so that tolerance generated during transitional installation can be realized, the perpendicularity between the lance tube 3 and the stagnant flow pore plate during operation of the lance tube 3 of the soot blower is ensured, and the phenomenon of jamming cannot occur.
The surface of the box body 1 is provided with a sealing air interface 11, and the sealing air interface 11 is communicated with an external sealing air source through a pipeline. The sealing air interface 11 can be connected with sealing air to prevent smoke from entering the wall box.
