Description

Technical Field

[0001] This utility model relates to the field of photosensitizer production technology, and in particular to a tail gas condensation adsorption device. Background Technology

[0002] Photosensitizers, also known as photoinitiators or photocuring agents, are compounds that absorb energy of a specific wavelength in the ultraviolet (250–420 nm) or visible (400–800 nm) light range, generating free radicals, cations, etc., thereby initiating monomer polymerization, cross-linking, and curing. The preparation process of photosensitizers is relatively complex, requiring a series of equipment including reaction vessels, oxidation vessels, synthesis vessels, alkali fusion vessels, crystallization vessels, refining vessels, filters, centrifuges, and dryers. The produced granular photosensitizers contain a certain amount of moisture and need to be dried in a dryer. Since water vapor is generated during the drying process, a dehumidification device is required to remove the water vapor generated during drying.

[0003] Existing dehumidification devices (such as the condensing dehumidifier disclosed in application number 201420227041.X) use condensation to dehumidify water vapor in exhaust gas. However, a small amount of water vapor will still be discharged with the exhaust gas because it cannot be condensed in time, resulting in poor dehumidification effect. Increasing the contact time between water vapor and condenser can improve the condensing dehumidification effect, but it will reduce the dehumidification efficiency. Utility Model Content

The two sealing rings are embedded in the two receiving grooves one to one. When the second side plate 2213 abuts against the outer wall of the adsorption box 210, the corresponding sealing ring abuts against the outer wall of the adsorption box 210. The sealing effect between the second side plate 2213 and the outer wall of the adsorption box 210 can be improved by the sealing rings.

[0031] As a preferred embodiment, please refer to Figure 1 and Figure 4The adsorption unit 200 further includes two connectors 230, which are respectively disposed on both sides of the adsorption box 210 and correspond one-to-one with the two second side plates 2213. When the second side plate 2213 abuts against the outer side wall of the adsorption box 210, the corresponding connector 230 can detachably connect the adsorption box 210 and the second side plate 2213, thereby realizing the detachable connection between the adsorption box 210 and the second side plate 2213.

[0032] As a preferred embodiment, please refer to Figure 4 The connector 230 includes multiple first connectors 231, multiple second connectors 232, and multiple connecting pins 233.

The activated carbon can adsorb the water vapor in the exhaust gas. The adsorbed exhaust gas is discharged through the second exhaust port 212 and the second exhaust pipe 250.

[0034] To better understand this utility model, the following is combined with... Figure 1 - Figure 5 The working principle of the technical solution of this utility model will be described in detail below: In use, the suction fan draws the exhaust gas from the dryer's chamber into the condenser 110. The condenser 120 condenses the water vapor in the exhaust gas into liquid water. After condensation, the exhaust gas enters the adsorption chamber 210 through the first exhaust port 112, the first exhaust pipe 140, and the second air inlet 211. The water in the condenser 110 can be discharged through the drain port 113. The activated carbon in the material box 221 adsorbs the water vapor in the exhaust gas. After adsorption, the exhaust gas is discharged through the second exhaust port 212 and the second exhaust pipe 250. When it is necessary to replace the activated carbon in the material box 221, the material box 221 is pulled out, causing the corresponding receiving cavity to move out of the adsorption chamber 210. The lower cover plate 2216 is then removed, and the receiving cavity... The activated carbon inside falls out, and then the lower cover plate 2216 is replaced on the opening on the lower surface of the receiving cavity. The upper cover plate 2215 is removed, and new activated carbon is filled into the receiving cavity. Then the upper cover plate 2215 is replaced on the opening on the upper surface of the receiving cavity. There are two receiving cavities. When the activated carbon in one of the receiving cavities is replaced, the activated carbon in the other receiving cavity can continue to adsorb water vapor in the exhaust gas in the adsorption box 210, so that the activated carbon can be replaced without stopping the machine. This exhaust gas condensation adsorption device uses condensation and adsorption to condense and adsorb water vapor in the exhaust gas for dehumidification. A small portion of water vapor that cannot be condensed in time can be adsorbed and dehumidified again by the adsorption element 220, which improves the dehumidification effect and dehumidification efficiency.

[0035] The exhaust gas condensation and adsorption device provided by this utility model has the following beneficial effects: (1) The detachable connection between the adsorption box 210 and the material box 221 makes disassembly and assembly convenient and improves disassembly and assembly efficiency; (2) There are two receiving cavities. When the activated carbon in one of the receiving cavities is replaced, the activated carbon in the other receiving cavity can continue to adsorb water vapor in the exhaust gas in the adsorption box 210, so that the activated carbon can be replaced without stopping the machine. (3) This exhaust gas condensation and adsorption device uses condensation and adsorption to condense and adsorb water vapor in the exhaust gas for dehumidification. Since a small portion of water vapor that cannot be condensed in time can be adsorbed and dehumidified again through the adsorption element 220, the dehumidification effect and dehumidification efficiency are improved.
