[0003] Although the current chemical dust removal separator has a good dust removal and separation effect, there are many harmful substances in the chemical workshop. After using it for a period of time, the current chemical dust removal separator will cause the dust removal and separation effect of the device to decline, especially the clogging problem of the filter layer. This requires frequent cleaning and maintenance of the device. The maintenance process is complicated, and a single cleaning and maintenance takes a long time. Moreover, the device cannot perform dust removal operations normally during cleaning and maintenance, which will affect the work progress of the chemical workshop.

[0004] Therefore, it is necessary to propose a chemical waste gas dust removal device to solve the above problems. Utility Model Content

[0029] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0031] See also Figure 1-4As shown, an embodiment of the present application provides a chemical waste gas dust removal device, including a dust removal tank 1, a bracket 105 is provided on the outer side of the bottom of the dust removal tank 1, an air inlet pipe 101 is provided on one side of the bottom of the dust removal tank 1, and an air outlet pipe 102 is provided on the top of the dust removal tank 1. The chemical waste gas is transported to the dust removal tank 1 through the air inlet pipe 101, and a filter assembly 2 is provided inside the dust removal tank 1. The filter assembly 2 includes two first filter layers 201 and a second filter layer 202. The outer sides of the two first filter layers 201 are fixedly connected to the inside of the dust removal tank 1, the inner side of the first filter layer 201 is fixedly connected to the first inner ring 2011, and the second filter layer 202 is located between the two first filter layers 201. The second filter layer 202 includes a movable ring 2021, and the inner side of the movable ring 2021 is provided with an inner filter layer 2022, and the inner side of the inner filter layer 2022 is provided with a second inner ring 2023. The filter assembly 2 is used to block harmful dust particles in the chemical waste gas. The first filter layer 20 1 and the second filter layer 202 have an inverted trapezoidal structure. A second filter layer 202 is set between the two first filter layers 201, so that the chemical waste gas is filtered by the first filter layer 201 while part of the gas passes through the first inner ring 2011 and is filtered by the inner filter layer 2022. Subsequently, part of the gas in the chemical waste gas passes through the gap between the movable ring 2021 and the inner filter layer 2022, and then contacts and filters the first filter layer 201 located above. In this process, it can avoid the problem that when multiple filter layers are used to purify and remove dust from chemical waste gas, the chemical waste gas treatment efficiency is too low and the parts are easily damaged due to the easy clogging of the filter layer located below. As a further improvement, in actual use, multiple groups of filter components 2 can be arranged at equal intervals in the dust removal tank 1 according to the needs of use, and the blocking particle size of the harmful dust particles in the chemical waste gas in the multiple groups of filter components 2 gradually increases from bottom to top to improve the cleaning efficiency of the harmful dust particles in the chemical waste gas.

[0032] Furthermore, a rotating assembly 3 and a lifting assembly 4 are provided below the dust removal tank 1. The rotating assembly 3 includes a motor 301. The rotating shaft of the motor 301 is provided with a rotating shaft 302. The top of the rotating shaft 302 passes through the dust removal tank 1, the inclined plate 104, the first inner ring 2011 and the second inner ring 2023 and is provided with a spray pipe 303. The lifting assembly 4 is a cylinder, and the second inner ring 2023 is fixedly connected to the rotating shaft 302 by a reinforcing rib 2024.

[0033] Rotating plate assemblies 2025 are provided at the top and bottom of the reinforcing rib 2024 . A scraper 2026 is provided at one end of the rotating plate assembly 2025 away from the reinforcing rib 2024 . In a normal state, the scraper 2026 does not contact the first filter layer 201 .

[0034] The rotating plate assembly 2025 includes a fixed end and a telescopic end. The fixed end is fixedly connected to the reinforcing rib 2024. An elastic member is provided between the fixed end and the telescopic end, and the elastic member is a spring.

[0035] An inclined plate 104 is provided at the lower part of the dust removal tank 1, and a drain pipe 103 is provided at the lower part of the inclined plate 104. Control valves are provided on the air inlet pipe 101, the air outlet pipe 102 and the drain pipe 103. The bottom end of the drain pipe 103 passes through the dust removal tank 1 and is located outside the dust removal tank 1. The inclined plate 104 serves as a gathering plate for the spray liquid, which can guide the liquid after contacting and reacting with harmful dust particles to the lower part of the inclined plate 104, thereby accelerating the efficiency of the liquid being discharged to the outside of the dust removal tank 1.

[0036] By starting the motor 301 in the rotating component 3, the second filter layer 202 will be driven to rotate between the two adjacent first filter layers 201. The rotation of the rotating plate component 2025 will disturb the airflow, making the upward airflow more uniform. In addition, the spray pipe 303 can spray alkaline liquid downward from the top of the inside of the dust removal tank 1 to neutralize the acidic substances in the exhaust gas. After the chemical waste gas dust removal device completes the purification and dust removal of the exhaust gas, the dust removal tank 1 and the filter component 2 are cleaned by spraying cleaning liquid downward to ensure the service life of the chemical waste gas dust removal device.

[0037] During the process of the spray pipe 303 spraying the alkaline liquid downward, the motor 301 drives the spray pipe 303 to disperse the spray liquid downward more evenly, and at the same time, the liquid can be thrown between the two adjacent first filter layers 201 on the inner wall of the dust removal tank 1 through the rotating plate assembly 2025. At this time, during the process of the lifting assembly 4 driving the rotating assembly 3 to move up and down repeatedly, the rotating plate assembly 2025 at the top and bottom of the reinforcing rib 2024 repeatedly collides with the two first filter layers 201, and the first filter layer 201 is scraped by the scraper 2026 to achieve the purpose of removing the dust particles accumulated on the two first filter layers 201. The cleaned dust particles are gathered inwardly through the inclined surfaces of the first filter layer 201 and the inner filter layer 2022, and then fall to the bottom of the dust removal tank 1 through the first inner ring 2011 and the second inner ring 2023.

[0038] Among them, a flexible pad layer can be set on the outside of the movable ring 2021, and the liquid and dust particles on the inner wall of the dust removal tank 1 can be scraped off by the flexible pad layer when the movable ring 2021 moves up and down, thereby improving the cleaning efficiency of the inner wall of the dust removal tank 1.

[0039] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
