Description

Technical Field

[0001] This utility model relates to the field of ash unloading devices, specifically to a system for preventing dust from escaping from ash unloading devices. Background Technology

[0002] In the production processes of industries such as coking and metallurgy, high-temperature flue gas carries a large amount of dust and tar, which needs to be treated by a dust removal system. Traditional ash unloading devices have the following problems: the pressure difference between the ash silo and the outside environment during ash unloading causes dust to escape, polluting the environment and endangering the health of operators; tar adheres to the inner wall of the dust collector, reducing dust removal efficiency and requiring frequent shutdowns for cleaning; the ash conveying system has poor sealing; and the ash discharge port lacks effective dust collection measures, forming a secondary pollution source.

[0003] Therefore, it is necessary to design a system to prevent dust from escaping from the ash unloading device, which can reduce dustfall, has multiple anti-escape structures, and make the production environment cleaner, ensuring the health of workers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a system for preventing dust from escaping from an ash unloading device, which can reduce dustfall, has multiple anti-escape structures, and can make the production environment cleaner and ensure the health of workers.

[0020] To make the technical solution of this utility model easier to understand, the technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1:

[0022] like Figure 1 As shown, a system for preventing dust emission from an ash unloading device according to this embodiment includes a raw flue gas outlet 1, wherein:

[0023] The original flue gas outlet 1 is connected to the original flue gas discharge pipe 2. One end of the original flue gas discharge pipe 2 is connected to the adsorption chamber 3. The bottom side of the adsorption chamber 3 is provided with a tar-removing flue gas outlet 4. One end of the tar-removing flue gas outlet 4 is connected to the dust collector collection pipe 5. One end of the dust collector collection pipe 5 is connected to the dust collector 6. The top side of the dust collector 6 is provided with a clean flue gas discharge pipe 7. A coal charging fan 8 is provided at one end of the clean flue gas discharge pipe 7. One end of the clean flue gas discharge pipe 7 is connected to the exhaust chimney 9.

[0024] The dust collector 6 is connected to a dust conveying plate 10 at the bottom. One end of the dust conveying plate 10 is connected to a dust conveying scraper 11. The conveying end of the dust conveying scraper 11 is connected to the ash hopper 12. The bottom of the ash hopper 12 is provided with an ash hopper cleaning pipe 13. One end of the ash hopper cleaning pipe 13 is connected to the ash discharge port 14.

[0025] The dust discharge port 14 is equipped with a dust collection hood 15 at one end. The dust collection hood 15 has a first opening 16 and a second opening 17 on one side. A first dust removal pipe 18 is connected to the first opening 16, and a second dust removal pipe 19 is connected to the second opening 17. The other end of the first dust removal pipe 18 is connected to a point of the dust collection pipe 5 of the dust collector, and one end of the second dust removal pipe 19 is connected to a point of the first dust removal pipe 18. A control valve 20 is provided on the first dust removal pipe 18.

[0026] The bottom of the dust collector 6 is connected to the dust conveying plate 10 by a flange seal, and an annular rubber sealing gasket is provided on the flange joint surface. The dust conveying plate 10 extends downward to the feed port of the ash conveying scraper 11.

[0027] The adsorption chamber 3 is equipped with an adsorption coke layer.

[0028] The dust collection hood 15 is provided with curtains 21 around its perimeter.

[0029] In operation, this device connects the original flue gas outlet 1 to the original flue gas discharge pipe 2 to deliver air containing flue gas and dust into the adsorption chamber 3. Inside the adsorption chamber, a coke adsorption layer is installed, which effectively adsorbs tar and reduces the tar content during the ash removal process.

[0030] After adsorption treatment, the flue gas enters the dust collector 6 through the tar-free flue gas outlet 4. During this process, the dust conveying plate 10 at the bottom of the system is sealed to the bottom of the dust collector 6 through a flange to ensure no air leakage. At the same time, the dust is sent to the ash conveying scraper 11 via the dust conveying plate and is finally stored in the ash silo 12.

[0031] A dust collection hood 15 is installed at the ash discharge port 14. The size of the dust collection hood 15 is the same as that of the dust transfer vehicle compartment, and a curtain 21 is added around it. The design of the dust collection hood 15 and the curtain 21 can capture any dust that may escape, avoiding environmental pollution. Through the first dust removal pipe 18 and the second dust removal pipe 19, a closed-loop dust removal structure is formed, which effectively reduces the impact of dust on the environment.

[0032] When ash is discharged from ash silo 12, the operator opens control valve 20 and operates coal charging fan 8 to high speed. The coal charging fan 8 collects the scattered dust into the dust collector, preventing unorganized discharge.

[0033] After the ash discharge operation is completed, control valve 20 is closed, and the dust removal facility resumes normal automatic operation. Through the above embodiments, in practical applications, this system can significantly reduce dust emission, playing a positive role in improving the working environment and operator safety, and reducing environmental risks.
