Description

Technical Field

[0001] This utility model relates to the field of dye processing technology, and more specifically, to a waste gas absorption tower for a food-grade pigment processing production line. Background Technology

[0002] Pigments are substances that can color objects. Pigments can be soluble or insoluble, and can be inorganic or organic. Inorganic pigments are generally mineral substances. Humans have known how to use inorganic pigments for a long time. Modern pigments are usually chemical products. A large amount of waste gas is generated during the production of pigments. This waste gas can re-pollute the pigments and needs to be absorbed and filtered. Therefore, waste gas absorption towers are needed.

[0003] A search revealed that CN214287429U discloses an absorption tower for ammonium sulfate tail gas after pigment processing, comprising a lower end cap, a cylindrical body, and an upper end cap. In use, tail gas is discharged into the cylindrical body through an inlet pipe. The tail gas rises naturally inside the cylindrical body, passing sequentially through a support ring, a grid, and a wire mesh demister. The wire mesh demister adsorbs the ammonium sulfate in the tail gas. Subsequently, water is injected into the cylindrical body through a circulation port and a liquid inlet pipe. The water flow adsorbs suspended particulate matter in the tail gas, preventing clogging of the wire mesh demister. The resulting wastewater is discharged through a drain port and recycled. The treated tail gas is discharged through an exhaust port. After completion, the lower manhole and handhole facilitate internal maintenance of the cylindrical body, and the wire mesh demister can be repaired or replaced by disassembling the cylindrical body flange. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing waste gas absorption towers in pigment processing production lines are often difficult to clean and maintain during operation, which can easily lead to cross-contamination of food-grade pigments and reduce the hygiene and safety of the products.

[0005] Therefore, a waste gas absorption tower for a food-grade pigment processing production line is proposed to address the above problems. Utility Model Content

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with existing technologies, this food-grade pigment processing production line exhaust gas absorption tower uses a detachable structure to regularly replace the packing material, and regularly cleans and disinfects the absorption tower to ensure the hygiene and safety of the products.

[0015] 2. Compared with the existing technology, the exhaust gas absorption tower of the food-grade pigment processing production line opens multiple vent holes inside the packing material, so that the cleaning liquid sprayed by the spray head is stored in the vent holes inside the packing material to form a water film. This not only facilitates the reaction of exhaust gas, but also prevents exhaust gas from being discharged directly through the packing material without purification. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 4 The exhaust gas absorption tower of a food-grade pigment processing production line shown includes a base 1, a cleaning component 2, a filter component 3, a support component 4, and an exhaust component 16. The support component 4 is arranged above the base 1, the filter component 3 is arranged above the support component 4, the cleaning component 2 is arranged above the filter component 3, and the exhaust component 16 is arranged above the cleaning component 2.

[0024] Specifically, the exhaust gas first enters the bottom of the tank 19 through the air inlet, and then rises from the bottom of the tank 19. It first enters the filter assembly 3 for filtration. The support assembly 4 can disassemble and assemble the filter assembly 3, making it convenient to replace and clean the internal components. The external cleaning assembly 2 can prevent the exhaust gas from coming into contact with the cleaning process and causing pollution.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the support assembly 4 includes a support frame 5, a sealing plate 6, and a pull plate 7. The sealing plate 6 is disposed above the support frame 5, and the pull plate 7 is installed on the outer diameter surface of the sealing plate 6. After a long reaction period, the pull plate 7 can be pulled to move the tray 8 and the filler 9, so as to replace the filler 9 and clean and maintain the interior to ensure the hygiene and safety of the product.

[0028] In a preferred embodiment, the filter assembly 3 includes a support plate 8, a filler material 9, and vent holes 10. The filler material 9 is disposed on the top of the support plate 8, and multiple vent holes 10 are provided inside the filler material 9. When the exhaust gas enters the absorption tower, it is first filtered by the filter assembly 3. The multiple vent holes 10 inside the filler material 9 can effectively absorb and lock in the cleaning liquid, so that a water film is formed on the surface of the filler material 9, and the exhaust gas is fully filtered.

[0029] In a preferred embodiment, the cleaning assembly 2 includes a spray head 11, a water pipe 12, a stop valve 13, a water tank 14, and a mounting bracket 15. The water tank 14 is fixed inside the mounting bracket 15, and the water pipe 12 is connected to the top of the water tank 14. The stop valve 13 is installed on the outer wall surface of the water pipe 12, and the spray head 11 is provided at the end of the water pipe 12 away from the water tank 14. By externally installing the water tank 14, contact with the product is avoided, thus preventing water source contamination. The water flow is controlled by the stop valve 13, and the spray head 11 sprays the internal filler 9 without contacting the exhaust gas, thus preventing pollution.

[0030] In a preferred embodiment, the exhaust assembly 16 includes a gas collection hood 17, a gas delivery pipe 18, and a tank 19. The gas collection hood 17 is disposed above the tank 19, and the gas delivery pipe 18 is disposed above the gas collection hood 17. The purified gas rises into the interior of the gas collection hood 17 and is discharged through the gas delivery pipe 18.

[0031] In a preferred embodiment, the pull plate 7 and the support plate 8 are fixedly connected, and the pull plate 7 and the support plate 8 form a sliding structure inside the tank body 19. By pulling the pull plate 7, the support plate 8 can be slid inside the tank body 19 for disassembly and assembly, which facilitates cleaning and replacement of the interior.

[0032] The working process of this utility model is as follows: First, the exhaust gas enters the bottom of the tank 19 through the air inlet and rises from the bottom of the tank 19. It first enters the filter assembly 3 for filtration. The support assembly 4 can disassemble and assemble the filter assembly 3 for easy replacement and cleaning of the interior. The external cleaning assembly 2 can prevent the exhaust gas from coming into contact with the cleaning process and causing pollution. When the exhaust gas enters the absorption tower, it first passes through the filter assembly 3 for filtration. The multiple vent holes 10 inside the packing material 9 can effectively absorb and lock in the cleaning liquid, forming a water film on the surface of the packing material 9, which fully filters the exhaust gas. After a long reaction, the pull plate 7 can be pulled to move the support plate 8 and the packing material 9 to replace the packing material 9 and clean and maintain the interior to ensure the hygiene and safety of the product.

[0033] By installing an external water tank 14, contact with the product is avoided to prevent water source contamination. The water flow is controlled by a stop valve 13, and the internal filling material 9 is sprayed through a spray head 11. This prevents contact with the exhaust gas and avoids pollution. The purified gas rises into the gas collection hood 17 and is discharged through the gas delivery pipe 18. The above describes the working principle of the exhaust gas absorption tower of this food-grade pigment processing production line.
