Generally speaking, any process that uses chemical methods to change the composition or structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical technology. The products produced by these processes are called chemical products or chemical industrial products. In chemical production, a ventilation device is essential. Therefore, in the field of chemical equipment, a special safety ventilation system needs to be adopted. In the production operations of chemical industrial parks, workshops need to carry out ventilation and filtration to ensure air circulation in the production area and improve the safety of operations.

[0003] During ventilation and filtration, chemical waste gas often contains harmful gases and particulate matters. These particulate matters are easily blocked by the filter plate and stay near the filter screen, making it difficult to discharge. Long-term filtration ventilation can also easily cause the filter screen to become blocked, thus affecting the ventilation and filtration effects. In addition, after the harmful substances accumulate, it is often necessary to open the ventilation duct, replace the filter plate, and clean the ventilation duct, which affects the working efficiency of the ventilation duct.

Detailed Embodiments

[0020] The preferred embodiments of the present utility model will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0021] A ventilation device for chemical industry safety includes an intake pipe 1 and a cleaning pipe 2. The rear end of the intake pipe 1 is communicated with the cleaning pipe 2, the rear end of the cleaning pipe 2 is communicated with an air inlet pipe 3, the air inlet pipe 3 is communicated with a blower 4, an air outlet pipe 5 is arranged below the blower 4, and a spraying mechanism 6 is arranged in the cleaning pipe 2. Starting the blower 4 can make gas enter the cleaning pipe 2. The impurities in the gas are combined with water mist to form particles and fall in the cleaning pipe 2, playing a role in purifying the gas. A first filter plate 7 is arranged in the cleaning pipe 2, a first cylinder 8 is arranged above the cleaning pipe 2, a first scraper 9 is arranged at the output end of the first cylinder 8, and the first scraper 9 is closely attached to the first filter plate 7. The first filter plate 7 can perform secondary filtration on the gas after spraying, with a better purification effect. The particles generated after filtration can start the first cylinder 8 to push out the first scraper 9 to scrape the particulate matter on the first filter plate 7. A second cylinder 10 is arranged on the left side of the cleaning pipe 2, a second scraper 11 is arranged at the output end of the second cylinder 10, and the bottom side of the second scraper 11 is closely attached to the bottom of the cleaning pipe 2. The second scraper 11 can scrape the particulate matter that falls during the spraying of the gas. A sewage outlet 12 is arranged in the cleaning pipe 2, and the right side wall of the sewage outlet 12 is flush with the first scraper 9.

[0022] Among them, a water tank 13 is arranged at the bottom of the cleaning pipe 2. The water tank 13 is communicated with the cleaning pipe 2, and a second filter plate 14 is arranged at the communication part of the water tank 13 and the cleaning pipe 2. The second filter plate 14 is flush with the bottom of the cleaning pipe 2. The water mist sprayed by the spraying mechanism 6 enters the water tank 13 after being filtered by the second filter plate 14, realizing the recycling of water.

[0023] Among them, the spraying mechanism 6 includes a spray head 601 and a water pipe 602. The spray head 601 is communicated with the water tank 13 through the water pipe 602.

[0024] Among them, a storage box 15 is arranged below the sewage outlet 12. A sliding groove 16 is arranged on the cleaning pipe 2, a sliding block 17 is arranged on the storage box 15, and the sliding groove 16 and the sliding block 17 are in sliding connection by matching. Through the sliding connection of the sliding groove 16 and the sliding block 17, it is convenient for the staff to install and disassemble the storage box 15.

[0025] Among them, fixing plates 18 are arranged on both sides of the cleaning pipe 2 and the storage box 15. Bolt holes are arranged on the fixing plates 18, and the cleaning pipe 2 and the storage box 15 are connected by fixing bolts 19.

[0026] Among them, the sliding groove 16 is a T-shaped space structure with a narrow outer part and a wide inner part, and the sliding block 17 is a T-shaped space structure with a wide outer part and a narrow inner part.

[0027] Working principle:

[0028] The staff first starts the blower 4, and inhales external gas into the air inlet pipe 3 through the air inlet pipe 3. The external gas enters the cleaning pipe 2 through the air inlet pipe 3. The spray head 601 in the cleaning pipe 2 sprays water mist. The harmful substances in the external gas form particulate matter with the water mist and fall in the cleaning pipe 2. Then, the harmful substances in the gas are filtered again at the first filter plate 7. The purified gas enters the blower 4 through the air inlet pipe 3 and is discharged from the air outlet pipe 5. The excess water mist sprayed by the spray head 601 is filtered by the second filter plate 14 and enters the water tank 13, and is sprayed again by the spray head 601 through the water pipe 602 to realize the recycling of water. When the harmful particulate matter on the first filter plate 7 and the second filter plate 14 accumulates too much, the first cylinder 8 and the second cylinder 10 are started, and the first scraper 9 and the second scraper 11 are pushed out to scrape the first filter plate 7 and the second filter plate 14 respectively. When scraping, there is no need to remove the cleaning pipe 2 to clean the filter plate, which improves the ventilation efficiency. The particulate matter after scraping falls into the storage box 15 through the sewage outlet 12 for collection. The staff can install and disassemble the storage box 15 through the fixing bolts 19 on the fixing plate 18 to process the harmful substances.
