Description

Technical Field

[0001] The utility model relates to the technical field of adsorption and separation of coal chemical industry and petrochemical industry, in particular to an adsorption device. Background Art

[0002] Adsorption equipment refers to equipment that uses the adsorption capacity of solids to purify harmful gases or liquids. Adsorption is the diffusion process of harmful gases or liquids on the interface when they come into contact with a certain solid substance. In the adsorption phenomenon, the solid substance with greater adsorption capacity is called an adsorbent, and the adsorbed substance is called an adsorbate.

[0003] The adsorption equipment commonly used in the chemical production process is a packed column adsorption device. The adsorbent inside this adsorption device is accumulated as a whole. When the adsorbent, especially the liquid adsorbent, flows into the adsorption device from the top of the adsorption device, the adsorbent continuously flows downward from the top of the adsorption device to the bottom of the adsorption device. The adsorbent continuously contacts the adsorbent for adsorption during the flow. However, due to the uneven flow velocity of the adsorbent along the radial direction of the adsorption device, the adsorbent with a faster flow rate can easily cause channeling inside the adsorbent, resulting in part of the adsorbent far away from the channel being unable to fully contact with the adsorbent, resulting in waste, resulting in the adsorbent in the adsorption device being unable to fully contact with the adsorbent, and then resulting in low adsorption efficiency of the adsorption device.

[0023] Please refer to Figure 1 The utility model provides an adsorption device, comprising: a tank body 1, in which a plurality of injection members 20 for passing an object to be adsorbed are arranged; a plurality of first filter mesh distribution plates 10, which are arranged in the tank body 1 at intervals along the axial direction of the tank body 1, and each first filter mesh distribution plate 10 is used to place an adsorbent, and the plurality of first filter mesh distribution plates 10 are arranged one by one corresponding to the plurality of injection members 20, so that the object to be adsorbed sprayed from each injection member 20 contacts the adsorbent on the corresponding first filter mesh distribution plate 10 for adsorption.

[0024] The utility model provides an adsorption device including: a tank body 1 and a plurality of first filter mesh distribution plates 10, wherein a plurality of injection parts 20 are arranged in the tank body 1, and each first filter mesh distribution plate 10 is used to place an adsorbent. The overall stacking mode of the adsorbent is changed by the plurality of first filter mesh distribution plates 10, and the spraying range of the object to be adsorbed is increased by the injection parts 20, thereby increasing the contact area between the adsorbent and the object to be adsorbed, so that the object to be adsorbed sprayed from each injection part 20 can be evenly sprayed onto the adsorbent on the corresponding first filter mesh distribution plate 10, so that a small amount of the object to be adsorbed is fully contacted with the adsorbent on the corresponding first filter mesh distribution plate 10 for adsorption, so that the object to be adsorbed does not need to flow down from the top of the adsorption device in large quantities, thereby avoiding insufficient contact between the object to be adsorbed and the adsorbent, thereby solving the problem of low adsorption efficiency of the adsorption device in the prior art and improving the adsorption efficiency of the adsorption device.

[0025] In the prior art, the overall accumulation of the adsorbent results in a large thickness. When the particles of the adsorbent are small, a small amount of the adsorbent to be adsorbed is easily blocked by the upper adsorbent when flowing into the adsorption device and cannot flow to the lower adsorbent, resulting in the lower adsorbent being unable to contact the adsorbent to be adsorbed, resulting in a decrease in the adsorption efficiency of the adsorption device. The present application separates the adsorbents that are piled together through multiple first filter mesh distribution plates 10, so that the thickness of the adsorbent on each first filter mesh distribution plate 10 is small, which helps the adsorbent to be adsorbed to flow more easily through the adsorbent on the first filter mesh distribution plate 10, and fully contact the adsorbent on the first filter mesh distribution plate 10, thereby improving the adsorption efficiency of the adsorption device.

[0026] In this embodiment, a plurality of first filter holes are arranged at intervals on each first filter distribution plate 10, and the apertures of the first filter holes of the plurality of first filter distribution plates 10 gradually decrease from the top to the bottom of the tank body 1; and / or the aperture of the first filter holes of the first filter distribution plate 10 closest to the top of the tank body 1 is smaller than the particle size of the adsorbent, so that the adsorbent can be evenly placed on the first filter distribution plate 10.

[0027] In this embodiment, the adsorption device also includes a second filter distribution plate 30, which is arranged below the first filter distribution plate 10 closest to the bottom of the tank body 1, and a plurality of second filter holes are arranged at intervals on the second filter distribution plate 30, wherein the aperture of the second filter hole is smaller than the aperture of the first filter hole, so as to filter the material to be adsorbed flowing out of the first filter hole to filter out the broken adsorbent in the material to be adsorbed.

[0028] Specifically, the aperture of the first filter hole of the first filter distribution plate 10 closest to the top of the tank body 1 is smaller than the particle size of the adsorbent. Such a setting avoids the aperture of the first filter hole being too large, causing the adsorbent to slip out of the first filter hole, resulting in the adsorbent being unable to be evenly placed on the first filter distribution plate 10, thereby ensuring that the adsorbent can fully contact with the object to be adsorbed, thereby ensuring the adsorption efficiency of the utility model.

[0029] Specifically, the apertures of the first filter holes of the multiple first filter distribution plates 10 gradually decrease from the top to the bottom of the tank body 1. Such an arrangement allows the broken adsorbent on a first filter distribution plate 10 to be collected by the multiple first filter distribution plates 10 below, so that the broken adsorbent can be filtered multiple times to prevent the broken adsorbent from flowing out of the tank body 1.

[0030] Optionally, three first filter mesh distribution plates 10 are arranged in sequence from the top to the bottom of the tank body 1, the aperture of the first filter hole of the top first filter mesh distribution plate 10 is larger than the aperture of the first filter hole of the middle first filter mesh distribution plate 10, and the aperture of the first filter hole of the middle first filter mesh distribution plate 10 is larger than the aperture of the first filter hole of the bottom first filter mesh distribution plate 10, so that after the adsorbent of the top first filter mesh distribution plate 10 is crushed, the crushed adsorbent can be collected by the two lower first filter mesh distribution plates 10, so that after the adsorbent of the middle first filter mesh distribution plate 10 is crushed, the crushed adsorbent can be collected by the lower first filter mesh distribution plate 10, and after the adsorbent of the bottom first filter mesh distribution plate 10 is crushed, the crushed adsorbent can be collected by the second filter mesh distribution plate 30. Among them, the aperture of the second filter hole is smaller than the aperture of the first filter hole of the bottom first filter mesh distribution plate 10.

[0031] In this embodiment, the first filter holes of any two adjacent first filter mesh distribution plates 10 among the plurality of first filter mesh distribution plates 10 are arranged to be connected, so that the adsorbent flows through the plurality of first filter mesh distribution plates 10 thereunder in sequence for multiple adsorptions.

[0032] Specifically, the adsorbed material flowing out of the first filter hole of the top first filter mesh distribution plate 10 can flow through the two lower first filter mesh distribution plates 10 in sequence to continue to be adsorbed, and the adsorbed material flowing out of the first filter hole of the middle first filter mesh distribution plate 10 can flow through the lower first filter mesh distribution plate 10 to continue to be adsorbed, thereby increasing the adsorption times of the adsorbed material, thereby improving the adsorption effect of the adsorbed material, and improving the adsorption efficiency of the adsorption device.

[0033] In this embodiment, the nozzle of each spraying member 20 is arranged opposite to the corresponding first filter distribution plate 10 , so that the adsorbed material sprayed from the nozzle is sprayed uniformly toward the corresponding first filter distribution plate 10 .

[0034] Specifically, the nozzles of each injection member 20 are arranged above the corresponding first filter distribution plate 10, which helps to evenly spray the adsorbed material sprayed from each nozzle to the corresponding first filter distribution plate 10, further increasing the contact area between the adsorbed material and the adsorbent, and further ensuring the adsorption efficiency of the adsorption device.

[0035] In this embodiment, a first flow hole connected to the second filter hole is provided on the bottom tank wall of the tank body 1, and the adsorption device also includes a recovery pipe 40 and a recovery component 50, and the two ends of the recovery pipe 40 are respectively connected to the first flow hole and the recovery component 50, so that the adsorbent flows through the second filter hole, the first flow hole and the recovery pipe 40 in turn and flows into the recovery component 50 to complete the recovery.

[0036] Specifically, the recovery pipe 40 is provided with a safety valve 41, a flow meter 42, a first filter 43, a pressure gauge 44, a main valve 45 and a recovery part 50 in sequence. The flow meter 42 and the pressure gauge 44 are respectively used to detect the flow rate and pressure of the adsorbent flowing out of the tank body 1, and then judge whether the adsorption resistance of the adsorbent in the tank body 1 is large and whether the pressure of the tank body 1 is large, so as to judge the adsorption efficiency of the adsorption device and perform maintenance. The recovery pipe 40 is used to connect the first flow hole and the recovery part 50, so that the adsorbent to be adsorbed in the tank body 1 is returned to the recovery part 50 through the recovery pipe 40.

[0037] Specifically, the second filter distribution plate 30 is used to filter the adsorbent to be adsorbed to prevent the broken adsorbent in the adsorbent from flowing into the recovery member 50 and clogging the first filter 43, resulting in frequent replacement of the first filter 43 and increasing the use cost of the adsorption device.

[0038] In this embodiment, the adsorption device further includes a plurality of observation holes 60 arranged on the tank wall of the tank body 1 , and each observation hole 60 is arranged between any two first filter distribution plates 10 so as to observe the first filter distribution plates 10 through the observation hole 60 .

[0039] In specific implementation, since the adsorbent on the first filter mesh distribution plate 10 in the middle and bottom of the tank body 1 will come into contact with the object to be adsorbed multiple times, the adsorbent on the first filter mesh distribution plate 10 in the middle and bottom is easily broken.

[0040] Specifically, there are two observation holes 60, which are respectively arranged on the first filter distribution plate 10 in the middle of the tank body 1 and above the first filter distribution plate 10 at the bottom. The operator can observe the usage of the adsorbent in real time through the observation hole 60, and the observation hole 60 can be closed. When the operator observes that the consumption of the adsorbent is high, the operator can replenish the material in time through the observation hole 60 and add new adsorbent to the corresponding first filter distribution plate 10 below the observation hole 60.

[0041] In this embodiment, the adsorption device also includes a plurality of feed pipes 70, and a plurality of feed holes 71 are arranged on the tank wall of the tank body 1. The plurality of feed pipes 70 are arranged one-to-one correspondingly to the plurality of feed holes 71, and the plurality of feed pipes 70 are arranged one-to-one correspondingly to the plurality of injection members 20. The pipe mouth of each feed pipe 70 is connected with the corresponding injection member 20 through the corresponding feed hole, so that the flow to be adsorbed in the feed pipe 70 enters the injection member 20 through the feed hole 71.

[0042] Specifically, the adsorption device further includes a discharge pipe 72, one end of each feed pipe 70 is connected to the discharge pipe 72, and the other end of each feed pipe 70 is connected to the corresponding feed hole 71. The multiple feed pipes 70 can realize the uniform diversion of a large amount of adsorbed material in the discharge pipe 72 to form a plurality of small amounts of adsorbed material, and each small amount of adsorbed material is sprayed onto the corresponding first filter screen distribution plate 10 through the corresponding feed hole 71 and the injection member 20 in sequence, further increasing the contact area between the adsorbed material and the adsorbent, which helps to improve the adsorption efficiency of the adsorption device.

[0043] In this embodiment, the adsorption device also includes a control valve 80, a pressure detection component 81 and a flow detection component 82. The control valve 80, the pressure detection component 81 and the flow detection component 82 are arranged on the feed pipe 70 in sequence along the flow direction of the object to be adsorbed. The control valve 80 can be set to be on and off to control the on and off of the control valve 80 according to the detection results of the pressure detection component and the flow detection component 82.

[0044] Specifically, the adsorption device also includes a second filter 83, which is arranged between the control valve 80 and the pressure detection component 81, and is used to filter the material to be adsorbed in the feed pipe 70 to prevent the first filter hole and the second filter hole from being blocked after the material to be adsorbed enters the adsorption device; the control valve 80, the pressure detection component 81 and the flow detection component 82 are all communicatively connected to the controller, and the controller controls the on-off of the control valve 80 according to the detection results of the pressure detection component and the flow detection component 82, and then controls the on-off of the feed pipe 70, so as to control the material to be adsorbed flowing into the adsorption device to meet the preset pressure and preset flow.

[0045] Optionally, the flow detection component 82 is a flow meter; and the pressure detection component 81 is a pressure gauge.

[0046] In this embodiment, the adsorption device also includes an exhaust pipe 90 arranged on the tank body 1, and a second flow hole is also arranged on the tank wall of the tank body 1.

[0047] Specifically, a valve is provided on the drain pipe 90. When the substance to be adsorbed is a gaseous substance, the valve is closed, so that the substance to be adsorbed passes through multiple first filter distribution plates 10 in sequence for adsorption. When the substance to be adsorbed is adsorbed, the valve is opened, and the substance to be adsorbed remaining above the tank body 1 can be discharged through the drain pipe 90, so as to avoid gas accumulation in the tank body 1 causing excessive air pressure in the tank body 1, thereby damaging the tank body 1.

[0048] Specifically, the adsorption device further includes a catalyst member 100 . The bottom of the tank body 1 is disposed in the catalyst member 100 . The catalyst member 100 is used to heat or cool the tank body 1 to provide a suitable adsorption environment for the tank body 1 .
