Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment equipment, specifically to a mechanism for handling air leakage in waste incineration boilers. Background Technology

[0002] Incinerators are commonly used for the harmless treatment of medical and domestic waste, as well as animal waste. Their principle is to utilize the combustion of fuels such as coal, oil, or gas to burn and carbonize the waste at high temperatures, achieving sterilization. A waste incinerator typically consists of four main systems: a waste pretreatment system, an incineration system, a flue gas biochemical treatment system, a dust removal system, and a gas generator (for auxiliary ignition and combustion).

[0003] Existing waste incineration boilers still have the following problems when in use: due to their high-temperature operating conditions and the fact that the main body of the waste incineration boiler is designed with a sealed structure, gaps are easily generated between adjacent components after prolonged high-temperature operation, which leads to air leakage in the waste incineration boiler. The leaked gas is mostly polluting gas, which will cause environmental problems. Utility Model Content

[0022] Please see Figures 1-4 In this embodiment of the utility model, the air leakage treatment mechanism for a waste incineration boiler includes a sealing mechanism 1. The sealing mechanism 1 includes a sealing bag 11 with an opening at the bottom. A through groove 12 is provided at the center of the inner top wall of the sealing bag 11. A sealing cover 15 is fixedly connected in the through groove 12. Through holes are symmetrically arranged between the upper and lower side walls of the sealing cover 15. A connecting valve 17 is fixedly installed at the top of the sealing cover 15 and at one of the through holes. A pressure gauge 16 is fixedly installed at the top of the sealing cover 15 and at the other through hole. The sealing bag 11 can cover the air leakage of the waste incineration boiler to quickly treat the air leakage. At the same time, it is equipped with a connecting valve 17 and a pressure gauge 16. The pressure gauge 16 can monitor the internal air pressure. The connecting valve 17 can be connected to the flue gas biochemical system of the waste incineration boiler. When the air pressure is too high, the gas is discharged to the flue gas biochemical system, which can effectively prevent the gas from leaking out directly and causing environmental problems.

[0023] A fastening mechanism 2 is provided below the sealing bag 11. The fastening mechanism 2 includes a first elastic metal strip 21 that is slidably connected to the outer wall below the sealing bag 11. A second elastic metal strip 24 is fixedly connected to one end of the first elastic metal strip 21. The fastening mechanism 2 is provided at the bag opening at the bottom of the sealing bag 11. After the sealing bag 11 is covered by the air leakage of the waste incineration boiler, the bag opening of the sealing bag 11 can be tightened by the fastening mechanism 2 to tighten the bag opening to its covering installation position to prevent air leakage at the bag opening.

[0024] A limiting frame 22 is fixedly connected between the upper and lower side walls of the front middle of the first elastic metal strip 21. A second elastic metal strip 24 is slidably connected inside the limiting frame 22.

The front end of the support block 23 is slidably connected to the second elastic metal strip 24. A threaded hole 25 is opened at the middle position of the front of the limiting frame 22. A locking screw 26 is threadedly connected inside the threaded hole 25. The second elastic metal strip 24 can be pulled to tighten the opening of the inner sealing bag 11. By turning the locking screw 26, the second elastic metal strip 24 is pressed backward against the rear support block 23 to achieve limiting and fastening.

[0025] The outer annular wall of the sealing bag 11 is fixedly connected with multiple tensile ribs 14 at equal angles, which serves to reinforce the structure around the sealing bag 11. The inner top wall of the sealing bag 11, located outside the through groove 12, is fixedly connected with an internal steel ring 13, which serves to reinforce the structure at the top of the sealing bag 11.

[0026] The working principle of this utility model is as follows: a fastening mechanism 2 is provided at the bottom opening of the sealing bag 11. After the sealing bag 11 is placed over the air leak in the waste incineration boiler, the opening of the sealing bag 11 can be tightened by the fastening mechanism 2. The second elastic metal strip 24 can be pulled to tighten the opening of the inner sealing bag 11, tightening the opening to its installation position. By tightening the locking screw 26, the second elastic metal strip 24 is pressed backward to the rear support block 23 to achieve limiting and fastening, preventing air leakage at the bag opening. Since it is equipped with a sealing bag 11, it can be placed over the air leak in the waste incineration boiler to achieve rapid treatment of the air leak. At the same time, it is equipped with a connecting valve 17 and a pressure gauge 16. The pressure gauge 16 can monitor the internal air pressure, and the connecting valve 17 can be connected to the flue gas biochemical system of the waste incineration boiler. When the air pressure is too high, the gas is discharged to the flue gas biochemical system, which can effectively prevent the gas from leaking out directly and causing environmental problems.
