Description

Technical Field

[0001] This invention relates to the field of adsorption device technology, and in particular to an adsorption device packing replacement structure and replacement method. Background Technology

[0002] When replacing granular packing materials (such as resin) used for organic solvent adsorption, manual removal of the packing material is required, which is not only time-consuming but also necessitates rinsing with large amounts of water, thus increasing wastewater discharge. Especially when replacing packing materials in solvent-based chemical adsorption devices, organic solvents are prone to volatilization, and using traditional reverse gas loosening methods can pollute the surrounding environment and affect the health of operators—something that those skilled in the art would find undesirable. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses an adsorption device packing replacement structure, comprising an adsorption device, a suction pump, a liquid injection pump, a suction pipe, a liquid injection pipe, and a filter device.

[0004] The adsorption device is equipped with a filler to be replaced. The filtration device includes a housing and a waste collection tank, a solution tank, a filter screen, and an adsorption structure located inside the housing. The filter screen is inclined on the solution tank, and the lowest point of the filter screen is located above the waste collection tank. The adsorption structure is located at the opening of the housing.

[0005] Both the suction tube and the injection tube extend into the adsorption device and are positioned close to each other. The input end of the injection pump is connected to the solution tank, and the output end of the injection pump is connected to the injection tube. The input end of the suction pump is connected to both the suction tube and the liquid outlet of the adsorption device. The output end of the suction pump is connected to the filter device to draw the packing material to be replaced onto the filter screen.

[0006] In some embodiments, the input end of the injection pump is connected to the solution tank via a first valve, the output end of the injection pump is connected to the injection pipe via a second valve, and the input end of the suction pump is connected to the suction pipe and the outlet of the adsorption device via a third valve and a fourth valve, respectively. The first, second, third, and fourth valves are used to regulate the flow rate, and the fourth valve can be closed as needed to enhance the suction of the suction pump.

[0007] In some of these embodiments, the filler is a resin.

[0008] In some embodiments, the filter screen surface is evenly distributed with multiple strip-shaped grooves, and a strip-shaped protrusion is provided between two adjacent strip-shaped grooves to prevent the filler from clogging.

[0009] In some embodiments, the tilt angle of the filter screen is adjustable, and the tilt angle of the filter screen is 55 to 70°, which can be adjusted according to the filtration requirements of the filler.

[0010] In some embodiments, the adsorption structure employs an activated carbon adsorption structure to adsorb waste gas generated during the filter media filtration process.

[0011] In some embodiments, the activated carbon adsorption structure is a drawer-type structure, and the activated carbon in the activated carbon adsorption structure adopts a honeycomb block-shaped structure or a bag-type structure for easy replacement.

[0012] In some embodiments, a filter layer and an exhaust fan are provided above the adsorption structure to further filter the exhaust gas and quickly discharge the filtered exhaust gas.

[0013] In some embodiments, a movable adsorber is provided above the adsorption device to adsorb waste gas leaking out of the adsorption device.

[0014] Furthermore, the present invention also discloses a method for replacing the packing material of an adsorption device, wherein, based on the above-mentioned adsorption device packing material replacement structure, the replacement method includes the following steps:

[0015] Start the suction pump to draw the liquid in the adsorption device into the solution tank;

[0016] Start the injection pump, and after loosening the packing material in the adsorption device using the injection pipe, use the suction pipe and suction pump to draw the loosened packing material onto the filter screen, and the packing material enters the waste collection tank after being filtered by the filter screen;

[0017] After all the packing material in the adsorption device has been drawn into the adsorption device, the injection pump and the suction pump are turned off.

[0018] Insert the suction tube and the injection tube into a new packing trough. After placing the output end of the suction pump into the adsorption device, use the injection tube to loosen the packing in the new packing trough, and use the suction pump and suction tube to draw the packing in the new packing trough into the adsorption device.

[0019] The above invention has at least the following advantages or beneficial effects:

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but these are not intended to limit the scope of the invention.

[0025] Example 1:

[0026] like Figure 1 As shown, this embodiment discloses an adsorption device packing replacement structure. The packing material in the adsorption device is generally resin, such as ion exchange resin. Specifically, the replacement structure includes an adsorption device 1, a suction pump 3, a liquid injection pump 4, a suction pipe 5, a liquid injection pipe 6, and a filter device 2. The adsorption device 1 is provided with the packing material to be replaced. The filter device 2 includes a housing 21 and a waste collection tank 23, a solution tank 22, a filter screen 24, and an adsorption structure 25 located inside the housing 21. The waste collection tank 23 and the solution tank 22 are arranged side by side at the bottom of the housing 21. The filter screen 24 is inclinedly arranged at the opening of the solution tank 22, and the lowest point of the filter screen 24 is located above the waste collection tank 23. The adsorption structure 25 is arranged at the top opening of the housing 21. Both the suction pipe 5 and the injection pipe 6 extend into the adsorption device 1, and the ends of the suction pipe 5 and the injection pipe 6 that extend into the adsorption device 1 are rigid pipes. The suction pipe 5 and the injection pipe 6 are positioned close together (including adjacent to each other) to facilitate simultaneous movement of the suction pipe 5 and the injection pipe 6 by hand or using a driving device (the injection pipe 6 is used to loosen the packing material in the adsorption device 1, and the suction pipe 5 is used to draw the loosened packing material into the filter device 2 for filtration). The input end of the injection pump 4 is connected to the solution tank 22, and the output end of the injection pump 4 is connected to the injection pipe 6 so that the liquid in the solution tank 22 can be reused. The input end of the suction pump 3 is connected to both the suction pipe 5 and the outlet of the adsorption device 1, and the output end of the suction pump 3 is connected to the filter device 2 to draw the packing material to be replaced onto the filter screen 24. The liquid in the adsorption device 1 is generally an organic solvent, but water can also be used. The liquid in the solution tank 22 is also an organic solvent or water, and correspondingly, the liquid used in the injection pump 4 is also an organic solvent or water.

[0027] Specifically, the input end of the injection pump 4 is connected to the solution tank 22 through the first valve V1, and the output end of the injection pump 4 is connected to the injection pipe 6 through the second valve V2. The input end of the suction pump 3 is connected to the suction pipe 5 and the outlet of the adsorption device 1 through the third valve V3 and the fourth valve V4, respectively. The first valve V1, the second valve V2, the third valve V3 and the fourth valve V4 are used to adjust the flow rate. The fourth valve V4 can be closed as needed to enhance the suction of the suction pump 3.

[0028] In a preferred embodiment of the present invention, the surface of the filter screen 24 is uniformly distributed with multiple strip-shaped grooves, and a strip-shaped protrusion is provided between two adjacent strip-shaped grooves to prevent the packing material from clogging during filtration. Specifically, if the packing material is an ion exchange resin, a strip-shaped filter screen with a gap of 0.2-0.25 mm can be used, that is, the width of the strip-shaped protrusion is 0.2-0.25 mm. The tilt angle of the filter screen 24 is adjustable, and the tilt angle of the filter screen 24 is 55-70°. The tilt angle of the filter screen 24 can be adjusted according to the filtration requirements of the packing material, thereby meeting the filtration requirements of packing materials with different compositions and particle sizes. Specifically, the tilt angle of the filter screen 24 is configured to be 60-65 degrees, the packing material automatically flows into the waste collection tank 23, and the liquid is filtered into the solution tank 22. The liquid is repeatedly reused by the injection pump 4, thereby reducing waste discharge.

[0029] In a preferred embodiment of the present invention, the adsorption structure 25 is an activated carbon adsorption structure for adsorbing waste gas generated during the filter media filtration process. This activated carbon adsorption structure is a drawer-type structure, specifically including three drawers, and the activated carbon in the structure adopts a honeycomb block structure or a bag-type structure to facilitate replacement of the activated carbon and achieve a better adsorption effect.

[0030] In a preferred embodiment of the present invention, a filter layer (not shown in the figure) and an exhaust fan 26 are provided above the adsorption structure 25 to further filter the exhaust gas and quickly discharge the filtered exhaust gas.

[0031] In a preferred embodiment of the present invention, a movable adsorber is provided above the adsorption device 1 to adsorb the waste gas leaking from the adsorption device 1 and prevent the waste gas from entering the room. For example, when the liquid injection pipe 6 and the suction pipe 5 are inserted into the adsorption device 1, waste gas may leak out, and the movable adsorber can adsorb the waste gas in time.

[0032] Example 2:

[0033] like Figure 2 As shown, this embodiment also discloses a method for replacing the packing material of an adsorption device. Based on the aforementioned adsorption device packing material replacement structure, the replacement method includes the following steps:

[0034] Step S1: Start the suction pump to draw the liquid in the adsorption device into the solution tank; specifically, the suction pump draws the liquid in the adsorption device onto the filter screen, and then the liquid passes through the filter screen into the solution tank for subsequent reuse.

[0035] Step S2: Start the injection pump and, after loosening the packing material in the adsorption device using the injection pipe (i.e., injecting the solution from the solution tank into the packing material through the injection pipe, thereby loosening the packing material), use the suction pipe and suction pump to draw the loosened packing material onto the filter screen. After being filtered by the filter screen, the packing material enters the waste collection tank 23. Specifically, after drawing the liquid from the adsorption device into the solution tank, and before the pneumatic injection pump, disconnect the fourth valve V4 to increase the suction force of the suction pump on the packing material.

[0036] Step S3: After all the packing material in the adsorption device has been drawn into the adsorption device, turn off the injection pump and the suction pump.

[0037] Step S4: Remove the suction tube and injection tube from the adsorption device and insert them into a new packing tank (which contains unused packing). After removing the output end of the suction pump from the filter device and placing it into the adsorption device, use the injection tube to loosen the packing in the new packing tank (at this time, the input end of the injection tube is still connected to the solution tank). Then, use the suction pump and suction tube to draw the packing from the new packing tank into the adsorption device.

[0038] It is not difficult to see that this embodiment is a method embodiment corresponding to the embodiment of the adsorption device packing replacement structure in Embodiment 1 above. This embodiment can be implemented in conjunction with the embodiment of the adsorption device packing replacement structure described above. The relevant technical details mentioned in the embodiment of the adsorption device packing replacement structure described above are still valid in this embodiment, and will not be repeated here to reduce repetition.
