Description

Technical Field

[0001] This utility model relates to the field of adhesive production technology, specifically to an exhaust gas purification device for adhesive production. Background Technology

[0002] The waste gas generated during the glue production process (hereinafter referred to as glue waste gas) is a complex industrial waste gas with specific hazards. Its characteristics are closely related to the glue formula and production process. In order to protect the environment, the waste gas needs to be purified during the glue production process.

[0027] In this embodiment, preferably, the discharge component 14 includes a discharge pipe 1401. The input end of the discharge pipe 1401 is fixedly connected to the bottom end of the purification tank 8. A discharge valve 1402 is fixedly installed at the output end of the discharge pipe 1401.

[0028] In this embodiment, preferably, both the top of the purification tank 1 and the top of the purification tank 8 are fixedly provided with protruding rings 19. The surface of the protruding rings 19 has grooves 21, and a sealing gasket 20 is engaged inside the grooves 21.

[0029] In this embodiment, preferably, an air inlet pipe 12 is fixedly provided at the bottom of the purification tank 1, and a one-way valve 15 is fixedly installed in the middle of the pulse air pipe 6, the middle of the air inlet pipe 12 and the middle of the desorption pipe 11. A flange is fixedly provided at the input end of the pulse air pipe 6, the input end of the air inlet pipe 12 and the input end of the desorption pipe 11. Waste gas can be input into the interior of the purification tank 1 through the air inlet pipe 12, and the one-way valve 15 can ensure the one-way flow of the medium.

[0030] In this embodiment, preferably, a connecting valve 22 is fixedly installed in the middle of the conduit 7, and an exhaust valve 13 is fixedly installed in the middle of the top of the second bucket cover 10. By opening the connecting valve 22, the communication between the first purification bucket 1 and the second purification bucket 8 can be ensured, and by opening the exhaust valve 13, the purified gas can be discharged.

[0031] During use, the operator first opens the connecting valve 22 and the exhaust valve 13, and closes the drain valve 3 and the discharge valve 1402 and steam discharge valve 1404 of the discharge component 14. Then, the waste gas generated from the production of glue is input through the air inlet pipe 12. When the waste gas rises to the filter screen 2, the filter screen 2 can pre-treat the waste gas, remove impurities in the waste gas, and reduce the impact on the activated carbon. When the pre-treated waste gas enters the purification tank 2 8 through the conduit 7, the permeable net 903 of the permeable support component 9 can ensure the permeability, allowing the waste gas to reach the activated carbon through the support bucket 901. Utilizing the porous structure of the activated carbon, the harmful substances in the waste gas can be adsorbed. After purification, the waste gas can be discharged through the exhaust valve 13.

[0032] When it is necessary to clean the filter screen 2, the staff closes the connecting valve 22 and opens the drain valve 3. Then, the pulse air pipe 6 is connected to the pulse blower, and pulse air is input into the bucket cover 4. The perforated plate 5 can ensure the uniform distribution of the pulse airflow, which can clean the filter screen 2 and remove impurities on the filter screen 2. The impurities can be discharged through the drain valve 3, which can ensure the ventilation capacity of the filter screen 2.

[0033] When activated carbon needs to be desorbed, the operator closes the exhaust valve 13, opens the steam exhaust pipe 1403, and inputs steam through the desorption pipe 11 to desorb the activated carbon. This ensures the adsorption capacity of the activated carbon and avoids adsorption saturation. After passing through the activated carbon, the steam can be discharged through the steam exhaust valve 1404. By connecting the steam exhaust valve 1404 to the condenser, the discharged steam can be condensed.

[0034] When activated carbon needs to be discharged, the discharge valve 1402 is opened. The support hopper 901 and the riser 902 can guide the activated carbon and discharge it into the purification tank 2 8. The vibration motor 23 vibrates the purification tank 1 and the purification tank 2 8, which can speed up the discharge speed and prevent clogging when discharging impurities and activated carbon.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
