[0002] Waste gas treatment refers to the treatment of industrial waste gas, which generally includes the steps of denitrification, dust removal and desulfurization. Because the reaction temperature required in the denitrification process is relatively high, denitrification treatment is carried out first to ensure the reaction temperature required for denitrification. In the subsequent desulfurization process, in order to prevent the dust in the flue gas from clogging the desulfurization water washing tower, dust removal is required first. After dust removal, the dust content in the flue gas is reduced, and finally desulfurization treatment is carried out.

[0003] Industrial waste gas generally refers to the particulate matter entrained in the flue gas produced by fuel combustion in the factory area of an enterprise. It is a type of solid particles suspended in the air for a certain period of time. These solid particles need to be removed as much as possible during the dust removal process. However, in the process of separating them from the waste gas, the long-accumulated dust can easily clog the dust removal device, resulting in poor dust removal effect and easy machine failure.

The denitrified exhaust gas carrying part of the dust is introduced into a drying mechanism 3 for the next step of treatment. A drying mechanism 3 is fixed on the left side of the denitrification tower 2 and passes through its interior. The drying mechanism 3 is used to guide the exhaust gas from the denitrification tower 2 that has undergone denitrification. It should be noted that the drying mechanism 3 includes an air pipe 301 fixed on the left side of the denitrification tower 2 and passing through its interior. A dryer 302 for drying the exhaust gas is installed on the outer surface of the air pipe 301. The dryer 302 is a prior art, and only a brief description of its working effect is given here. The dryer 302 can dry the exhaust gas with moisture in the air pipe 301, so that the dust is in a dry state and prevents it from sticking together due to moisture.

[0025] It should be noted that a collecting pipe 303 is fixed on the left side of the gas supply pipe 301. The collecting pipe 303 is a three-way pipe with three openings, and the other two output ends of the collecting pipe 303 are respectively facing left and downward.

[0028] During operation, the dryer 302 dries the exhaust gas with moisture inside the air supply pipe 301. The exhaust gas enters the interior of the collecting pipe 303 through the right opening thereof, and is introduced into the dust removal mechanism 4 from the left opening thereof for further dust removal. Part of the dust sinks through the bottom opening of the collecting pipe 303 and falls into the dust bag 305.

[0029] See also Figure 3-4 In order to further separate the dust in the exhaust gas, the dust removal mechanism 4 in this embodiment includes a dust removal tower 401 fixed to the left side of the drying mechanism 3 and penetrated by it. It should be noted that the front of the dust removal tower 401 is hinged with a sealed door, which can be opened when the mechanism is not in operation to facilitate maintenance of the internal equipment. The front of the sealed door is inlaid with an observation window, which can be used by the operator to observe from the outside.

[0030] Furthermore, the bottom of the dust removal tower 401 is fixed with support legs 402 fixed to the top of the base 1 on all sides, the inner surface of the dust removal tower 401 is slidably connected with a sliding plate 403, the top of the sliding plate 403 is detachably connected with a filter cartridge 404 that penetrates to its bottom, and the bottom of the sliding plate 403 is fixed with a scraper ring 405 that fits the inner surface of the dust removal tower 401 on all sides. The scraper ring 405 at its bottom is driven by the sliding plate 403 to move up and down repeatedly, constantly scraping the inner surface of the dust removal tower 401 to prevent dust from adhering to the inner surface of the dust removal tower 401. The left and right sides of the dust removal tower 401 are fixed with a filter that penetrates its interior and The lifting assembly 406 fixed to the sliding plate 403, it should be noted that the left lifting assembly 406 includes a mechanism box 4061, a motor 4062 and a transmission shaft 4063, the mechanism box 4061 is fixed to the left side of the dust removal tower 401 and is penetrated into its interior by the drying mechanism 3, the motor 4062 is fixed to the left side wall of the inner cavity of the mechanism box 4061, and the output shaft of the motor 4062 points to the left, the motor 4062 runs, and its output shaft rotates, the transmission shaft 4063 is fixed to the output shaft of the motor 4062 and penetrates into the interior of the dust removal tower 401, and the output shaft of the motor 4062 drives the transmission shaft 4063 to rotate.

The hinge rod 4068 is rotatably connected to the outer surface of the fixed rod 4065 and is hinged to the hinge seat 4067. The fixed rod 4065 drives the hinge rod 4068 to move up and down, and pushes and pulls the sliding plate 403 up and down through the generated hinge force, so that it drives the filter cartridge 404 on its top to vibrate up and down, so that the dust filtered on its inner surface falls to the bottom of the dust removal tower 401.

[0032] It should be noted that the dust removal mechanism 4 is fixed to the base 1, and the cross-section of the support leg 402 is L-shaped.

[0033] In addition, an exhaust assembly is fixed on the top of the dust removal tower 401 and extends into the interior thereof. It should be noted that the exhaust assembly includes an exhaust pipe 407 fixed on the top of the dust removal tower 401 and extends into the interior thereof.

[0035] In addition, a lower ash pipe 410 is fixed to the bottom of the dust removal tower 401 and penetrates into the interior thereof. The dust falling to the bottom of the dust removal tower 401 is discharged through the lower ash pipe 410. A second solenoid valve 411 is fixed to the bottom of the lower ash pipe 410. The second solenoid valve 411 can control the connection and closing of the lower ash pipe 410.

[0036] In general, the motor 4062 drives the rotating plate 4064 to rotate through the transmission shaft 4063, thereby driving the eccentrically set fixed rod 4065 to rotate up and down, causing the hinged rod 4068 to reciprocate up and down, and the generated hinge force pushes and pulls the sliding plate 403 up and down, causing the filter cartridge 404 on its top to vibrate up and down, allowing the dust to fall to the bottom of the dust removal tower 401, and driving the scraper ring 405 to move up and down repeatedly, constantly scraping the inner surface of the dust removal tower 401 to prevent dust from adhering.

The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0038] The working principle of the above embodiment is:

[0039] During use, the dryer 302 dries the exhaust gas with moisture in the air delivery pipe 301. The exhaust gas enters the collection pipe 303 through the right opening and is introduced into the dust removal tower 401 from the left opening for further dust removal. Part of the dust sinks through the bottom opening of the collection pipe 303 and falls into the dust bag 305, which can be used to collect a large amount of dust. The motor 4062 runs, and its output shaft drives the transmission shaft 4063 to rotate. The transmission shaft 4063 drives the rotating plate 4064 to rotate, thereby driving the eccentric fixed rod 4065 to rotate.
