Description

Technical Field

[0001] The utility model relates to the technical field of methanol washing, in particular to a methanol washing tower. Background Technique

[0002] Methanol, also known as hydroxy methane, wood alcohol or wood spirit, is an organic compound and the simplest saturated monohydric alcohol in structure;

[0003] For the separation and recovery of methanol, an absorbent is usually sprayed into a washing tower. However, a considerable part of the absorbent will contact the packing layer, resulting in uneven distribution of the liquid on the packing layer, thereby reducing the absorption rate of methanol in the gas by the liquid. The Chinese utility model patent with the publication number CN213885617U discloses a methanol washing tower, which includes a tower body, a liquid distribution component and a packing layer. The upper and lower parts of the tower body are respectively provided with a liquid inlet and a gas inlet, and the top and bottom are respectively provided with a gas outlet and a liquid outlet. The packing layer is arranged inside the tower body and is located between the liquid inlet and the gas inlet. The liquid distribution component is arranged inside the tower body and is communicated with the liquid inlet for evenly distributing the liquid on the packing layer to contact with methanol. By arranging a liquid distribution component communicated with the liquid inlet inside the tower body, the liquid water entering the tower body can be evenly distributed on the packing layer through the liquid distribution component, so that the methanol entering the tower body can fully contact with the liquid water, thereby effectively improving the absorption rate of methanol in the gas by the liquid;

[0004] In the above technology, a water delivery pipeline is arranged around the tower body near the liquid inlet, so that the water entering the tower body can flow into the liquid diversion pipeline more quickly and then flow onto the packing layer, thereby further improving the absorption rate of methanol in the gas by the liquid water. However, the liquid contains some impurities, which will cause certain blockage when passing through the liquid spraying component, thereby affecting the spraying effect and the absorption rate of formaldehyde. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a methanol washing tower to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0036] A pull rod 8, one end of which is connected to the fixing plate 7, and the other end of the pull rod 8 is connected with a fixing piece;

[0037] The liquid inside the liquid inlet 2 is filtered by the filter screen 5 inside the filter box 3 to prevent impurities from entering the inside of the scrubbing tower body 1. The fixing plate 7 slidably arranged on one side of the filter screen 5 can move up and down along the surface of the filter screen 5 through the cooperation of the pull rod 8 to clean the surface of the filter screen 5 and prevent impurities from blocking the filter holes on the filter screen 5.

[0038] Embodiment 2:

[0039] As Figures 2 - 4As shown in the figure, the methanol scrubbing tower disclosed in the second embodiment of the present utility model has basically the same structure as that in the first embodiment, and the differences are as follows:

[0040] A guiding groove 6 is formed in the inner wall of the filter box 3 at the position corresponding to the filter net 5, and the length of the guiding groove 6 matches the internal size of the filter box 3;

[0041] Both ends of the fixing plate 7 are slidably arranged inside two groups of guiding grooves 6. The fixing plate 7 reciprocates up and down along the filter net 5 through the guiding grooves 6, and a receiving groove 10 is formed at one end of the fixing plate 7 facing the filter net 5. A cleaning plate 9 is inserted into the receiving groove 10, and the size of the cleaning plate 9 matches the internal size of the receiving groove 10;

[0042] A first return spring 11 is arranged between the cleaning plate 9 and the receiving groove 10. There are multiple groups of the first return springs 11, and the multiple groups of first return springs 11 are evenly spaced. The cleaning plate 9 is attached to the surface of the filter net 5 through the multiple groups of first return springs 11;

[0043] The liquid inside the liquid inlet 2 is filtered by the filter net 5 arranged inside the filter box 3 to prevent impurities from entering the liquid spraying assembly and causing certain blockage. At the same time, a slidable fixing plate 7 is arranged on one side of the filter net 5. During the sliding process of the fixing plate 7, the elastically arranged cleaning plate 9 is driven to slide synchronously. During the sliding process of the cleaning plate 9, the impurities adhering to the surface of the filter net 5 are cleaned to prevent the filter holes on the filter net 5 from being blocked.

[0044] Embodiment Three:

[0045] As Figures 5 - 7 shown, the methanol scrubbing tower disclosed in the third embodiment of the present utility model has basically the same structure as that in the second embodiment, and the differences are as follows:

[0046] One end of a pull rod 8 penetrates through the filter box 3 in a sealed manner and is connected with a fixing member. The fixing member includes a fixing rod 4. A relief groove 14 is formed at one end of the fixing rod 4. The pull rod 8 is inserted into the relief groove 14, and a second return spring 15 is arranged between the pull rod 8 and the relief groove 14. The fixing rod 4 is elastically sleeved on the pull rod 8 through the second return spring 15;

[0047] A clamping block 16 is fixedly arranged at one end of the fixing rod 4 close to the side wall of the filter box 3. The cross section of the clamping block 16 is in a "T" shape. A clamping groove 13 is formed at the upper end surface of the filter box 3 at the position corresponding to the clamping block 16, and the clamping groove 13 matches the clamping block 16;

[0048] The engaging groove 13 is of a semi-circular structure, and a sunk groove 12 is formed at the upper end surface of the filter box 3 corresponding to the position of the engaging groove 13.

[0049] To prevent the fixing plate 7 from being pulled out randomly, a fixing rod 4 is provided at the end of the pull rod 8. When fixing the fixing plate 7 through the fixing rod 4, the clamping block 16 provided on the fixing rod 4 is clamped inside the sunk groove 12, and then the fixing rod 4 is rotated. The fixing rod 4 drives the clamping block 16 to rotate into the engaging groove 13. Through the cooperation of the clamping block 16 and the engaging groove 13, the fixing rod 4 is limited, and further the fixing plate 7 is limited.

[0050] The specific scheme is as follows: The liquid is injected into the interior of the scrubbing tower body 1 through the liquid inlet 2, so that the liquid is evenly sprayed on the packing layer, which facilitates the full mixing of methanol in the tower with the liquid. At the same time, when the liquid passes through the filter box 3, it will be filtered by the filter net 5 provided inside the filter box 3 to prevent impurities in the liquid from entering and affecting the washing efficiency of methanol;

[0051] When it is necessary to clean the surface of the filter net 5, the fixing rod 4 is rotated. When the clamping block 16 rotates from the inside of the engaging groove 13 to the inside of the sunk groove 12, the fixing plate 7 can be driven by the pull rod 8 to move along the surface of the filter net 5. During the movement, the elastically arranged cleaning plate 9 removes the impurities adhering to the surface of the filter net 5.
