Description

Technical Field

[0001] The utility model relates to a high-efficiency adsorption and desorption device for a laboratory, belonging to the technical field of desorption. Background Art

[0002] Desorption is the reverse process of adsorption, which refers to the process of a substance detaching from a solid surface. During the desorption process, the adsorbed substance leaves the adsorbent surface to regenerate the adsorbent. Desorption usually occurs under certain conditions, such as heating, reducing pressure, displacement and flushing. The degree of desorption has an important influence on re-adsorption. Therefore, in practical applications, adsorption and desorption processes are often used in combination to achieve the purpose of separation, purification or regeneration of the adsorbent. Due to the particularity of the use environment, laboratories often need to use adsorption devices to purify the air and adsorb toxic and harmful gases or impurities in specific environments.

[0003] The adsorption and desorption structure box in the existing laboratory high-efficiency adsorption and desorption devices is usually integrated. The adsorption and desorption of impurities need to be completed in the adsorption and desorption structure cavity. It is impossible to remove the adsorbed activated carbon and other adsorbents from the adsorption and desorption structure cavity separately, and thus it is impossible to carry out thorough and efficient desorption, so that adsorbents such as activated carbon cannot achieve better regeneration purposes, affecting the re-adsorption effect of the adsorbent.

[0025] A support bar 12 is provided on the upper surface of the bottom of the inner cavity of the protection box 2, and a slide rail 13 adapted to the annular groove 11 is provided on the upper surface of the support bar 12. The support bar 12 is used to connect the slide rail 13 to the upper surface of the bottom of the inner cavity of the protection box 2. The slide rail 13 allows the activated carbon storage box 4 to slide within the protection box 2 in a limited manner.

[0026] Sliders 14 are provided on both sides of the activated carbon storage box 4, and slide grooves 15 adapted to the slides 14 are opened on the inner walls on both sides of the protection box 2. The slides 14 and the slide grooves 15 are used to limit and embed the main body of the activated carbon storage box 4. The hollow sealing door 6 is fixed to the activated carbon storage box 4 by bolts to prevent the hollow sealing door 6 from opening when the activated carbon storage box 4 is pulled.

[0027] The edge of the side opening of the protection box 2 is provided with an embedding groove 16, the inner edge of the sealing door 7 is provided with an embedding block 17 adapted to the embedding groove 16, and a high-temperature resistant sealing gasket 26 is provided on the side of the edge of the sealing door 7 close to the embedding block 17. The embedding groove 16 and the embedding block 17 allow the sealing door 7 to fit more closely in the opening on the side of the protection box 2 to increase the sealing performance.

[0028] The sealing door 7 is provided with reinforcement blocks 18 around it, and the reinforcement blocks 18 extend to the protection box 2. The reinforcement blocks 18 are fixed to the protection box 2 by bolts. The reinforcement blocks 18 can fix the sealing door 7 to the protection box 2 by bolts from the outside, thereby increasing the firmness and sealing of the sealing door 7.

[0029] An exhaust pipe 19 is provided through the top of the protection box 2, an air intake pipe 20 is provided through the bottom of the protection box 2, an exhaust slot 21 is provided through the top of the activated carbon storage box 4, an air intake slot 22 is provided through the bottom of the activated carbon storage box 4, and a switch air valve 27 is provided on the air intake pipe 20.

[0030] The protection box 2 and the base 1 are fixed via a plurality of connecting columns 23 , and the connecting columns 23 are used to connect and fix the protection box 2 and the base 1 . Two handles 24 are symmetrically provided on the outer surface of the sealing door 7 .

[0031] like Figure 1-5As shown, the principle of the laboratory high-efficiency adsorption and desorption device provided in this embodiment is as follows: when the device is in use, the exhaust gas enters the activated carbon storage box 4 in the protection box 2 through the air inlet pipe 20, and the activated carbon on the plate 5 in the activated carbon storage box 4 will adsorb the exhaust gas, and the gas after multi-layer adsorption treatment will be discharged from the exhaust pipe 19;

[0032] When the activated carbon on the plate 5 placed in the activated carbon storage box 4 is in a saturated state after a long period of adsorption, it is impossible to continue to effectively adsorb the exhaust gas, and it is necessary to close the switch valve 27 to prevent the exhaust gas from entering again. The operator unscrews the bolts on the reinforcement block 18, removes the sealing door 7 through the handle 24, and then pulls the activated carbon storage box 4 out of the protection box 2, pushes the activated carbon storage box 4 with the desorbed activated carbon into the protection box 2, and then fixes the sealing door 7 to the protection box 2 through bolts, ensuring that the switch valve 27 can be opened after the installation is completed, so that the exhaust gas enters the activated carbon storage box 4 again, and is adsorbed by the activated carbon on the plate 5 placed in the activated carbon storage box 4 after desorption;

[0033] Then the operator processes the activated carbon storage box 4 filled with saturated activated carbon taken out from the protective box 2, unscrews the bolts on the hollow sealing door 6, takes out the saturated activated carbon and performs targeted desorption treatment. The activated carbon that has been desorbed can be loaded back into the activated carbon storage box 4 again, waiting for the next replacement of the activated carbon storage box 4 in the protective box 2.
