Description

Technical Field

[0001] This utility model relates to the field of boiler ash removal technology, specifically a modular ash removal device for hazardous waste heat boilers. Background Technology

[0002] Waste heat boilers, as the name suggests, are boilers that utilize the residual heat from waste gas, waste materials, or waste liquids generated in various industrial processes, as well as the heat generated from the combustion of combustible substances, to heat water to a certain temperature. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with waste heat recovery and utilization functions such as smoke boxes and flues are also called waste heat boilers.

[0003] Traditional boiler ash removal equipment typically uses high-pressure water guns to clean the inside of the boiler. However, this method is not only inefficient, but also requires subsequent filtration of residues in the water and is wasteful of water resources, resulting in low overall efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular ash removal device for hazardous waste heat boilers. This addresses the problem mentioned in the background that traditional boiler ash removal equipment typically uses high-pressure water guns to clean the boiler's interior, which is inefficient and requires subsequent filtration of residues in the water. Furthermore, this method is wasteful of water resources, resulting in low overall efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular ash removal device for a hazardous waste heat boiler, comprising a boiler body and a steam generator. A boiler cover is provided at the top of the boiler body, a pressure relief valve is fixedly installed at the top of the boiler cover, a pressure gauge is provided at the top of the boiler cover, the detection end of the pressure gauge penetrates through the boiler cover, an air inlet pipe is provided on the boiler cover, a threaded block is provided on the air inlet pipe, an air supply pipe is provided on the steam generator, a connector is rotatably installed at the end of the air supply pipe, a threaded groove is opened at the inner end of the connector, the threaded groove and the threaded block are threadedly engaged, and a high-pressure nozzle is provided at the inner end of the air inlet pipe.

[0006] Using the above technical solution, the connector installed at the end of the gas supply pipe is aligned with the gas inlet pipe on the boiler cover. Rotating the connector causes the threaded groove inside the connector to mesh with the threaded block on the gas inlet pipe, thus ensuring a stable connection between the gas inlet pipe and the gas supply pipe. The connector also has a sealing ring, which effectively prevents steam leakage when it is ejected into the high-pressure nozzle. After the steam enters the gas inlet pipe through the gas supply pipe, it is ejected from the high-pressure nozzle, thus performing steam cleaning on the boiler body. This cleans away dirt and impurities adhering to the inner wall of the boiler body, improving the cleaning effect.

[0007] Preferably, a shock wave generator is fixedly installed on one side of the boiler body, the top of the shock wave generator is provided with an inlet, and two connecting pipes are provided inside the shock wave generator.

[0008] Using the above technical solution, compressed air is introduced into the shock generator through the inlet set at the top of the shock generator. Then, when it is necessary to clean the dust inside the boiler body, the compressed air stored in the shock generator is sprayed out through the shock nozzle through the connecting pipe set on the shock generator, thereby cleaning the dust inside the boiler body.

[0009] Preferably, a gas release mechanism is provided on the right end face of the connecting pipe, and a shock wave nozzle is provided on the other end of the connecting pipe.

[0010] Using the above technical solution, compressed air is ejected through a shock wave nozzle to clean the dust inside the boiler body. Then, the pressure relief valve in the gas release mechanism controls the sealing diaphragm to either block the opening of the connecting pipe or disengage the sealing diaphragm from the opening of the connecting pipe. When the sealing diaphragm blocks the opening of the connecting pipe, it isolates the shock wave generator from the connecting pipe. When the sealing diaphragm disengages from the opening of the connecting pipe, it allows the compressed air inside the shock wave generator to enter the connecting pipe.

[0011] Preferably, a connecting pipe is provided between the two connecting pipes in the shock generator, and a turbulence generator is provided on the connecting pipe.

[0012] By adopting the above technical solution, a turbulence device is installed on the connecting pipe. The turbulence device can block and disturb the airflow flowing through the connecting pipe. By installing a turbulence device on the connecting pipe, the membrane rupture time is reduced, thereby enhancing the speed of shock wave ejection.

[0013] Preferably, the gas release mechanism includes a pressure release valve and a sealing diaphragm connected to the pressure release valve.

[0014] Using the above technical solution, the sealing diaphragm is controlled by the pressure relief valve in the gas release mechanism, so that the sealing diaphragm blocks the opening of the connecting pipe or disengages from the opening of the connecting pipe. When the sealing diaphragm blocks the opening of the connecting pipe, the sealing diaphragm isolates the shock wave generator from the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The modular ash removal equipment of this hazardous waste heat boiler connects the connector installed at the end of the air supply pipe to the air inlet pipe on the boiler cover. Rotating the connector causes the threaded groove inside the connector to mesh with the threaded block on the air inlet pipe, ensuring a stable connection between the air inlet pipe and the air supply pipe. A sealing ring inside the connector effectively prevents steam leakage when it is ejected into the high-pressure nozzle. After the steam enters the air inlet pipe through the air supply pipe, it is ejected from the high-pressure nozzle, thus performing steam cleaning on the boiler body. This cleans the dirt and impurities adhering to the inner wall of the boiler body, improving the cleaning effect.

[0017] 2. The modular ash removal equipment of this hazardous waste heat boiler sends compressed air into the shock generator through an inlet at the top of the shock generator. When it is necessary to clean the ash inside the boiler body, the compressed air stored in the shock generator is ejected through the shock nozzle via a connecting pipe on the shock generator to clean the dust inside the boiler body. Then, a turbulence device is installed on the connecting pipe. The turbulence device can block and disturb the airflow flowing through the connecting pipe. By installing a turbulence device on the connecting pipe, the film breaking time is reduced, thereby increasing the speed of shock jet. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Referring to Figures 1-4, a modular ash removal device for a hazardous waste heat boiler is described. The boiler body 1 has a boiler cover 2 at its top. A pressure relief valve 3 is fixedly installed at the top of the boiler cover 2. A pressure gauge 4 is installed at the top of the boiler cover 2, with its detection end penetrating the boiler cover 2. An air inlet pipe 5 is installed on the boiler cover 2, and a threaded block 6 is installed on the air inlet pipe 5. An air supply pipe 8 is installed on the steam generator 7, and a connector 9 is rotatably installed at the end of the air supply pipe 8. A threaded groove 10 is formed at the inner end of the connector 9, and the threaded groove 10 and the threaded block 6 are threadedly engaged. A high-pressure nozzle 11 is installed at the inner end of the air inlet pipe 5.

[0026] Working principle: After ash removal is completed inside the boiler body 1, some small particles of residue will inevitably remain. The operator aligns the connector 9 at the end of the air supply pipe 8 with the air inlet pipe 5 on the boiler cover 2. Rotating the connector 9 causes the threaded groove 10 inside the connector 9 to engage with the threaded block 6 on the air inlet pipe 5, thus establishing a stable connection between the air inlet pipe 5 and the air supply pipe 8. The connector 9 also has a sealing ring, which effectively prevents steam from escaping. When steam is sprayed into the high-pressure nozzle 11, a leak occurs. After the steam enters the air inlet pipe 5 through the air supply pipe 8, it is sprayed out from the high-pressure nozzle 11 through the air inlet pipe 5, thereby cleaning the boiler body 1 with steam, thus cleaning some dirt and impurities attached to the inner wall of the boiler body 1, thereby improving the cleaning effect inside the boiler body 1. After the steam cleaning is completed, the operator can release the pressure inside the boiler body 1 through the pressure relief valve 3 and observe the pressure inside the boiler body 1 through the pressure gauge 4.

[0027] Example 2:

[0028] Referring to Figures 1-4, a modular ash removal device for a hazardous waste heat boiler is described. A shock wave generator 12 is fixedly installed on one side of the boiler body 1. An inlet 13 is provided at the top of the shock wave generator 12. Two connecting pipes 14 are provided inside the shock wave generator 12. A gas release mechanism 15 is provided on the right side of the connecting pipe 14. A shock wave nozzle 16 is provided at the other end of the connecting pipe 14. A connecting pipe 17 is provided between the two connecting pipes 14 inside the shock wave generator 12. A turbulence generator 18 is provided on the connecting pipe 17. The gas release mechanism 15 includes a pressure relief valve and a sealing diaphragm connected to the pressure relief valve.

[0029] Working principle: Compressed air is supplied to the shock generator 12 through the inlet 13 at the top of the shock generator 12. When it is necessary to clean the ash inside the boiler body 1, the compressed air stored in the shock generator 12 is ejected through the shock nozzle 16 via the connecting pipe 14 on the shock generator 12 to clean the ash inside the boiler body 1. Then, the pressure relief valve in the gas release mechanism 15 controls the sealing diaphragm to seal the opening of the connecting pipe 14 or to open the sealing diaphragm. When the diaphragm detaches from the opening of the connecting pipe 14 and seals the opening of the connecting pipe 14, the sealing diaphragm isolates the shock generator 12 from the connecting pipe 14. When the sealing diaphragm detaches from the opening of the connecting pipe 14, the compressed air in the shock generator 12 can enter the connecting pipe 14. Then, a turbulence device 18 is provided on the connecting pipe 17. The turbulence device 18 can block and disturb the airflow flowing through the connecting pipe 17. By providing the turbulence device 18 on the connecting pipe 17, the membrane rupture time is reduced, thereby enhancing the speed of the shock wave ejection.
