[0002] Industrial waste gas refers to the general term for various pollutant gases released into the air during fuel combustion and production processes within industrial plants. These gases include harmful gases such as carbon dioxide, carbon disulfide, hydrogen sulfide, and fluoride, as well as harmful solids such as lead, mercury, beryllium, smoke, and industrial dust. These pollutants can cause certain hazards when released into the atmosphere. Waste gas treatment and purification primarily involves the management of industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and hazardous gases generated in industrial sites. Because waste gas contains mixed smoke particles, if not pre-filtered and removed, these mixed smoke particles can clog the filter element. Therefore, a dust removal device must be installed at the front end of the waste gas treatment equipment.

[0003] Existing waste gas dust removal devices mostly adopt a fixed filter element structure. This type of filter element has a good filtering effect in the early stage of use. However, since the filter element is fixed, dust particles are easily concentrated and adhered. After a period of use, the gas flowability will deteriorate rapidly and requires regular cleaning and maintenance. The maintenance cycle is short and the maintenance operation is frequent. In addition, there is no effective self-cleaning structure set inside the filter element. The filter element needs to be manually disassembled and cleaned for cleaning, and the maintenance convenience is poor. Therefore, an exhaust gas dust removal device for exhaust gas treatment equipment is proposed. Utility Model Content

In order to facilitate the discharge of treated exhaust gas, an exhaust end pipe 4 is provided on the upper part of the cylinder seat top cover 2. The air intake end pipe 3 and the exhaust end pipe 4 are connected.

[0025] The dust removal mechanism is used for dust removal of exhaust gas. The dust removal mechanism is installed inside the dust removal cylinder seat 1. The dust removal device includes a drive motor 6, an exhaust fan blade 7, a drive shaft column 8 and a dust removal drum 9. The exhaust fan blade 7 and the dust removal drum 9 are both installed inside the dust removal cylinder seat 1 through the drive shaft column 8. Figure 2 As shown, in order to facilitate the installation and support of the drive shaft column 8, a rotating shaft support is provided inside the dust removal cylinder seat 1. The drive shaft column 8 is rotatably installed inside the dust removal cylinder seat 1 under the support of the rotating shaft support. The exhaust fan blades 7 are located above the dust removal drum 9. The exhaust fan blades 7 are fixedly installed on the upper part of the drive shaft column 8. The dust removal drum 9 is fixedly installed on the lower part of the drive shaft column 8. In order to rotatably support the dust removal drum 9 and close the lower lateral gap of the dust removal drum 9, a drum support 12 is fixed on the inner lower part of the dust removal cylinder seat 1, and the lower part of the dust removal drum 9 is rotatably engaged with the rotating groove provided in the middle part of the drum support 12.

[0026] In order to improve the installation and support stability of the dust removal drum 9, as shown in the attached Figure 5 As shown, an auxiliary support rod 11 is provided on the lower opening side of the dust removal drum 9, and as shown in the attached Figure 6 As shown, the cross section of the auxiliary support rod 11 is trapezoidal, and the auxiliary support rod 11 is tilted. When the dust removal drum 9 rotates, the rotation of the auxiliary support rod 11 can improve the air circulation. In order to perform the dust removal operation, as shown in the attached Figure 5 As shown, a dust filter element 10 is installed inside the dust removal drum 9. In order to install and support the dust filter element 10, a metal mesh cover is fixedly installed on the circumference of the dust removal drum 9. The dust filter element 10 is fixedly installed on the inner circumference of the dust removal drum 9. When working, the dust removal drum 9 drives the dust filter element 10 to rotate. While avoiding the concentrated adhesion of smoke particles, the centrifugal action can improve the gas flowability, thereby improving the dust removal efficiency and service life of the dust filter element 10.

[0027] The driving motor 6 is used to drive the rotation of the shaft column 8. Figure 5As shown, the drive motor 6 is installed on the upper part of the drive shaft 8. In order to facilitate the installation and support of the drive motor 6, a motor bracket 13 is fixed inside the dust collector seat 1. The drive motor 6 is fixedly installed inside the dust collector seat 1 through the motor bracket 13.

The maintenance cycle of the dust filter element 10 can be effectively extended in conjunction with the rotary working mode.

[0028] In order to facilitate the centralized collection of dust during maintenance, as shown in the attached Figure 2 As shown, the lower part of the dust collector seat 1 is an inverted cone structure, and the lower part of the dust collector seat 1 is provided with a dust cleaning end pipe 5. The dust cleaning end pipe 5 is connected and installed in the lower part of the dust collector seat 1, and the dust bag can be connected and installed during maintenance operations.

[0029] Working principle or structural principle: when working, the dust cleaning end pipe 5 is in a closed state, and the exhaust gas enters the dust removal cylinder seat 1 through the air inlet end pipe 3. At the same time, the exhaust fan blades 7 and the dust removal drum 9 rotate at high speed under the drive motor 6. Under the suction action of the exhaust fan blades 7, the exhaust gas enters the dust removal drum 9 from the bottom, and after being filtered by the dust removal filter element 10, the dust-removed exhaust gas is discharged upward through the peripheral side of the dust removal drum 9, and then discharged from the exhaust end pipe 4 under the suction action of the exhaust fan blades 7, and enters the next level of processing equipment to complete the dust removal work of the exhaust gas;

[0030] After completing the dust removal work, when maintaining the equipment, close the air intake end pipe 3 and open the dust cleaning end pipe 5, then put the dust collecting bag on the open side of the dust cleaning end pipe 5, and then start the equipment. The exhaust fan blades 7 and the dust removal drum 9 rotate in opposite directions under the drive of the drive motor 6. The reverse air circulation causes the dust particles adhering to the inner side of the dust removal filter element 10 to fall off and be collected and stored by the dust collecting bag, completing the daily cleaning and maintenance of the equipment.

[0031] The dust collecting device adopts a rotary filter element structure, utilizes the dust collecting drum 9 to connect and install the dust collecting drum 10, and drives the dust collecting drum 9 to rotate by the driving motor 6. During operation, the dust collecting drum 9 drives the dust collecting drum 10 to rotate, and the centrifugal action can be used to improve the gas flowability and the service life of the dust collecting drum 10. The driving motor 6 drives the dust collecting drum 9 and the exhaust fan blades 7 synchronously, and provides driving suction for the exhaust gas circulation while completing the self-rotation drive of the dust collecting drum 9, which can effectively improve the circulation and filtering efficiency of the exhaust gas. After the dust removal operation is completed, the reverse flushing and cleaning of the dust collecting filter element 10 can be achieved by utilizing the reversal of the exhaust fan blades 7. The daily cleaning and maintenance work can be completed without the need for manpower to disassemble the dust collecting filter element 10, which greatly improves the maintenance convenience of the device, and the maintenance cycle of the dust collecting filter element 10 can be effectively extended in conjunction with the rotary working mode.
