[0002] Low-boiling-point materials such as acetone and methyl acrylate are used in the production process of 1,3-cyclohexanedione. A vacuum pump device is used in the production process of 1,3-cyclohexanedione, so non-condensable gas will be generated. The main components of the non-condensable gas are substances such as acetone, methyl acrylate and nitrogen. Due to the low boiling points of acetone and methyl acrylate, although the production device is equipped with a -15°C condensation system, a certain amount of acetone and methyl acrylate still exists in the tail gas.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-5 The utility model provides a device for treating 1,3-cyclohexanedione tail gas: comprising a support frame 1 and the top of the support frame 1 is fixedly connected to an operating table 2, an air intake block 3 is fixedly installed on the top of the operating table 2, a conveying assembly is fixedly connected to the rear end of the air intake block 3, a deashing assembly is fixedly installed on the bottom of the conveying assembly, a mounting block 10 is fixedly installed on the top of the support frame 1, a suction assembly is installed inside the mounting block 10, an activated carbon plate 11 is installed inside the mounting block 10, and an exhaust pipe 17 is fixedly installed on the outer wall of the mounting block 10. When in use, the suction assembly is started, and the tail gas generated in the production process will directly enter the inside of the air intake block 3, and then enter the deashing assembly through the conveying assembly, and enter the inside of the mounting block 10 after the dust in the tail gas is filtered by the deashing assembly, and the activated carbon plate 11 filters the methyl acrylate in the tail gas. The tail gas after two filtrations is finally discharged through the exhaust pipe 17.

[0022] The conveying assembly includes a first air intake pipe 5 and a connecting pipe 6. Two symmetrically distributed first air intake pipes 5 are fixedly installed at the rear end of the air intake block 3. The connecting pipe 6 is fixedly connected between the two first air intake pipes 5. When in use, the exhaust gas generated during the production process enters the interior of the air intake block 3 through the air extraction assembly, then enters the interior of the first air intake pipe 5, and then enters the deashing assembly through the connecting pipe 6.

[0023] The dust removal assembly includes a first air pipe 7, a filter tank 8 and a second air pipe 9. The first air pipe 7 is fixedly connected to the bottom of the connecting pipe 6, the filter tank 8 is fixedly connected to the bottom of the first air pipe 7, and the second air pipe 9 is fixedly connected to the top of the filter tank 8. When in use, first, water is added to the inside of the filter tank 8. When the exhaust gas enters the inside of the first air pipe 7, it enters from the bottom of the filter tank 8 and passes through the water from bottom to top. The water removes dust from the exhaust gas, and then the exhaust gas is transported upward through the second air pipe 9 to the inside of the mounting block 10.

[0024] The exhaust component includes a bracket 14, a drive motor 15 and a fan 16. The bracket 14 is fixedly connected to the inside of the mounting block 10. The drive motor 15 has two fixed mounting brackets 14. The fan 16 is fixedly mounted with the output end of the drive motor 15. When in use, the drive motor 15 is started, and the output end of the drive motor 15 drives the fan 16 to rotate. Since the conveying component, the dust removal component and the mounting block 10 are interconnected, the fan 16 generates suction when rotating, and can suck the exhaust gas generated in the production process into the conveying component.

[0025] The outer wall of the activated carbon board 11 is fixedly connected with a slider 12, the interior of the mounting block 10 is provided with a slide groove 13 corresponding to the slider 12, the outer wall of the activated carbon board 11 is fixedly connected with a handle 18, the outer wall of the mounting block 10 is movably provided with a block 19, the outer wall of the activated carbon board 11 is fixedly connected with a first support block 20 for supporting the block 19, and the outer wall of the mounting block 10 is fixedly connected with a second support block 21 for supporting the block 19. After the production is completed, a large amount of methyl acrylate will remain on the activated carbon board 11. At this time, the block 19 is rotated clockwise so that it is located at the top of the 2 support frame 1, and then the activated carbon board 11 is pulled out of the mounting block 10 by the handle 18 and cleaned. After the cleaning is completed, the activated carbon board 11 is installed back into the interior of the mounting block 10 by the cooperation of the slider 12 and the slide groove 13, and then the block 19 is rotated counterclockwise to clamp the block 19 on the top of the first support block 20 to prevent the activated carbon board 11 from falling.

[0026] A grille 4 is installed on the inner outer wall of the air intake block 3. When the air extraction component is started, a strong suction force will be generated. At this time, the grille 4 can prevent the objects on the operating table 2 from being sucked into the interior of the air intake block 3.

[0027] Working principle: When the utility model is used, first, the drive motor 15 is started, and the output end of the drive motor 15 drives the fan 16 to rotate to generate suction, so that the air intake block 3 also generates suction. The exhaust gas generated during the production of 1,3-cyclohexanedione will be directly introduced into the interior of the air intake block 3, and pass through the first air intake pipe 5, the connecting pipe 6, the first air pipe 7 and the second air pipe 9 in sequence, and enter through the bottom of the filter tank 8, and then pass through water from bottom to top. The water removes the dust in the exhaust gas, and then the exhaust gas is transported upward through the second air pipe 9 to the interior of the mounting block 10, and the activated carbon plate 11 filters the methyl acrylate in the exhaust gas. The exhaust gas after two filtrations is finally discharged through the exhaust pipe 17.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
