Description

Technical Field

[0001] The present invention relates to the technical field of adsorption separation, and in particular to an adsorption separation device for capturing organic components in VOCs and a method for using the same. Background Art

[0002] VOCs (volatile organic compounds) is a general term for organic compounds that are easily volatile at room temperature; VOCs have significant impacts on the environment and health. They are important precursors of air pollution, participate in the formation of ozone and fine particulate matter, and may cause problems such as haze and photochemical smog. In addition, some VOCs such as benzene and formaldehyde are toxic and may cause harm to human health, such as causing cancer and allergies. VOCs come from a wide range of sources, mainly natural sources and anthropogenic sources. Natural sources include biosphere emissions, while anthropogenic sources mainly include industrial production, transportation, solvent use, etc.

[0003] In industrial production, VOCs need to be purified before they can be discharged; common purification methods include adsorption, absorption, membrane separation, etc. Among them, the adsorption method uses the adsorption effect of adsorbents (such as activated carbon, zeolite molecular sieves, etc.) to separate VOCs from waste gas. The adsorption method is suitable for gaseous pollutants with medium concentrations and flows. It has the advantages of simple operation and low equipment investment. It is one of the most widely used methods in industrial production.

[0004] The common adsorption method for purifying VOCs on the market is to collect industrial gas through a collection device and transport it to an adsorption chamber, where an adsorbent is placed. When the gas passes through, the adsorbent automatically absorbs the organic components in the VOCs. Since the existing adsorption methods mostly use the natural flow method, that is, the industrial gas passes through the adsorbent by the normal pressure difference, the flow speed is slow, resulting in a relatively low adsorption efficiency.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0027] See also Figure 1 to Figure 8 , In an embodiment of the present invention, an adsorption separation device for capturing organic components in VOCs includes a mounting frame 1 for mounting an air intake duct 2; The mounting frame 1 is provided with a plurality of adsorption tank bodies 3, and the plurality of adsorption tank bodies 3 are symmetrically arranged; an air intake channel 301 and an air exhaust channel 302 are installed on the adsorption tank body 3; the air intake channel 301 is communicated with the air intake pipe 2; an adsorption column 13 communicated with the air exhaust channel 302 is installed in the adsorption tank body 3; The adsorption tank body 3 is provided with a drainage-assisting mechanism and an opening and closing mechanism; the drainage-assisting mechanism comprises a boosting disc 10 which is slidably engaged with the adsorption column 13; The opening and closing mechanism includes a plurality of sealing blocks 15 rotatably mounted on the air inlet passage 301; The boost disk 10 can slide along the adsorption column 13 to approach or move away from the exhaust duct 302; during the approach process, the air flow rate on the side of the boost disk 10 close to the exhaust duct 302 will increase; during this process, the multiple groups of sealing blocks 15 will first remain away from each other to allow air to enter the side of the boost disk 10 away from the exhaust duct 302, and then the multiple groups of sealing blocks 15 will rotate close to each other to block the air inlet duct 301.

[0028] Taking the embodiment combining all the features recorded in the present application as an example, when in use, the adsorption column 13 is made of a material having the ability to adsorb organic components (such as activated carbon, etc.); and has certain pores, so that air can pass smoothly; when the air mixed with organic components passes through the adsorption column 13, the organic components will be adsorbed by the adsorption column 13.

[0029] The air intake duct 2 is connected to a collecting device, and the air mixed with organic components generated during the production process will be collected by the collecting device and transported to the air intake duct 2.

[0030] After the adsorption tank 3 inhales air from the air intake pipe 2, the device is started to drive the boost disk 10 to move toward the exhaust channel 302 through the exhaust auxiliary mechanism to compress the air on the side of the boost disk 10 close to the exhaust channel 302; as the boost disk 10 continues to approach, the air pressure will continue to increase, thereby increasing the flow rate of air entering the exhaust channel 302 through the adsorption column 13, and as the pressure continues to increase, the adsorption efficiency of the adsorption column 13 will also increase.

[0031] When the boost disk 10 approaches the exhaust duct 302, the opening and closing mechanism will first keep the sealing blocks 15 separated from each other so that the air in the intake pipe 2 is sucked into the adsorption tank 3, thereby improving the adsorption efficiency; thereafter, the opening and closing mechanism will drive the sealing blocks 15 to rotate closer to each other to block the intake duct 301.

[0032] Afterwards, the exhaust assisting mechanism will drive the boost disc 10 away from the exhaust duct 302 to reset the device; during the resetting process, the air inlet duct 301 will first remain blocked to prevent air backflow caused by resetting; during this process, the air will flow from the side of the boost disc 10 away from the exhaust duct 302 to the side close to the exhaust duct 302; finally, the opening and closing mechanism will drive the sealing block 15 to rotate away to open the air inlet duct 301, so that the boost disc 10 can compress the air smoothly.

[0033] The exhaust-assisting mechanism and the opening and closing mechanism cooperate with each other, injecting new air into the air intake box adsorption tank 3 during the exhaust process; and compressing the air through the exhaust-assisting mechanism to increase the air circulation speed and air pressure on the adsorption column 13, which can effectively improve the adsorption efficiency and avoid air stagnation and incomplete adsorption due to slow air flow rate and low adsorption efficiency.

[0034] In another embodiment of the present invention, the exhaust-aiding mechanism also includes a lifting sleeve 9 that is slidably engaged with the adsorption column 13; a rotating sleeve 11 is rotatably installed on the lifting sleeve 9, and a sealing disk 1101 is installed on the rotating sleeve 11; an air guide groove 1001 is provided on the boosting disk 10; the air guide groove 1001 cooperates with the sealing disk 1101; a matching groove group 12 is provided on the rotating sleeve 11; a protruding column 303 that is slidably engaged with the matching groove group 12 is installed in the adsorption tank body 3.

[0035] In another embodiment of the present invention, the mating groove group 12 includes a first straight groove 1201, a first oblique groove 1202, a second straight groove 1203 and a second oblique groove 1204; wherein one end of the first straight groove 1201 is connected to one end of the first oblique groove 1202, and the other end of the first oblique groove 1202 is connected to one end of the second straight groove 1203; the other end of the second straight groove 1203 is connected to one end of the second oblique groove 1204; and the other end of the second oblique groove 1204 is connected to the other end of the first straight groove 1201.

[0036] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the lifting sleeve 9 moves on the adsorption column 13 toward the exhaust duct 302, it will drive the boosting plate 10 to move synchronously. At this time, the air guide groove 1001 and the sealing plate 1101 cooperate with each other, so that the air on the side of the boosting plate 10 close to the exhaust duct 302 will not flow to the side away from the exhaust duct 302, so that the boosting plate 10 can compress the air; by continuously squeezing the air to increase the circulation rate of the air on the adsorption column 13 and improve the adsorption efficiency of the adsorption column 13, it can effectively avoid the occurrence of air stagnation and incomplete adsorption caused by slow air flow rate and low adsorption efficiency.

[0037] During this process, the protruding column 303 slides in the first straight groove 1201, so the rotating sleeve 11 does not rotate, and the sealing disk 1101 and the air guide groove 1001 remain in a matching state; and the opening and closing mechanism will keep the sealing blocks 15 separated from each other, so that during the movement of the boost disk 10, the air in the intake pipe 2 can be drawn into the adsorption tank body 3. At this time, the newly entered air will gather on the side of the boost disk 10 away from the exhaust duct 302. As the boost disk 10 moves, the air in the adsorption tank body 3 will continue to increase.

[0038] When the protruding column 303 slides into the first inclined groove 1202 , most of the air on the side of the pressurizing disk 10 close to the exhaust channel 302 has entered the exhaust channel 302 through the adsorption column 13 .

[0039] Then, the lifting sleeve 9 is driven to move toward the exhaust channel 302. At this time, the protruding column 303 slides in the first inclined groove 1202. Through the continuous squeezing of the protruding column 303 on the first inclined groove 1202, the rotating sleeve 11 will rotate, thereby driving the sealing disk 1101 to rotate, so as to release the matching state between the sealing disk 1101 and the air guide groove 1001, so that the air guide groove 1001 is in a conducting state. In this process, the opening and closing mechanism will move in an arc to drive the sealing blocks 15 to rotate and approach each other, so as to gradually block the air intake channel 301; when the protruding column 303 slides to the second straight groove 1203, the air intake channel 301 is completely blocked, and the conducting area of ​​the air guide groove 1001 is the largest.

[0040] Then, the lifting sleeve 9 is driven away from the exhaust channel 302. At this time, the protruding column 303 will slide in the second straight groove 1203, and the rotating sleeve 11 will not rotate, so the air guide groove 1001 will remain in the conductive state, so that during the reset process, the air on the side of the booster disc 10 away from the exhaust channel 302 will not be compressed, thereby reducing the reset resistance, and the conductive air guide groove 1001 allows the air on the side away from the exhaust channel 302 to enter the side close to the exhaust channel 302, so as to facilitate the next auxiliary exhaust, thereby improving the adsorption efficiency. At the same time, since the air inlet channel 301 is in a blocked state, the air in the adsorption tank body 3 will not flow back during the reset process of the booster disc 10.

[0041] When the protruding column 303 slides to the second inclined groove 1204, the adsorption tank body 3 will be filled with newly injected air; then it will continue to drive the lifting sleeve 9 to move, thereby driving the protruding column 303 to slide in the second inclined groove 1204, and through the squeezing of the second inclined groove 1204 by the protruding column 303, the rotating sleeve 11 is driven to rotate, so as to drive the sealing disk 1101 to rotate until it is re-matched with the air guide groove 1001; and in this process, the opening and closing mechanism will drive the sealing blocks 15 to rotate away from each other to open the air inlet channel 301.

[0042] The exhaust-assisting mechanism and the opening and closing mechanism cooperate with each other, injecting new air into the air intake box adsorption tank 3 during the exhaust process; and compressing the air through the exhaust-assisting mechanism to increase the air circulation speed and air pressure on the adsorption column 13, which can effectively improve the adsorption efficiency and avoid air stagnation and incomplete adsorption due to slow air flow rate and low adsorption efficiency.

[0043] In another embodiment of the present invention, the opening and closing mechanism includes a first gear 304 rotatably installed in the adsorption tank body 3; the first gear 304 is slidably engaged with the rotating sleeve 11; a second gear 14 is rotatably installed on the air inlet channel 301; an opening and closing inclined groove 1401 is provided on the second gear 14; and a raised column 1501 is installed on the sealing block 15 and is slidably engaged with the opening and closing inclined groove 1401.

[0044] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the protruding column 303 slides in the first inclined groove 1202, the rotating sleeve 11 will rotate, and at this time the first gear 304 will also rotate synchronously; the first gear 304 and the second gear 14 are meshed with each other, thereby driving the second gear 14 to rotate, thereby driving the opening and closing inclined groove 1401 to rotate; thereby driving the protruding column 1501 to slide in the opening and closing inclined groove 1401, and the sliding direction is from the end of the opening and closing inclined groove 1401 away from the air inlet channel 301 to the end close to the air inlet channel 301; thereby driving the sealing block 15 to rotate until all the sealing blocks 15 collide with each other to block the air inlet channel 301.

[0045] When the protruding column 303 slides in the second inclined groove 1204, the rotating sleeve 11 will rotate in the opposite direction, thereby driving the protruding column 1501 to slide in the opening and closing inclined groove 1401, and the sliding direction is from the end close to the air inlet channel 301 to the end away from the air inlet channel 301. At this time, the sealing block 15 will rotate away from each other to open the air inlet channel 301.

[0046] The exhaust-assisting mechanism and the opening and closing mechanism cooperate with each other, injecting new air into the air intake box adsorption tank 3 during the exhaust process; and compressing the air through the exhaust-assisting mechanism to increase the air circulation speed and air pressure on the adsorption column 13, which can effectively improve the adsorption efficiency and avoid air stagnation and incomplete adsorption due to slow air flow rate and low adsorption efficiency.

[0047] In another embodiment of the present invention, a bracket 101 is installed on the mounting frame 1, and a lever 7 is rotatably installed on the bracket 101; a connecting seat 8 is slidably installed on one end of the lever 7, and the connecting seat 8 is fixedly connected to the lifting sleeve 9; a slider 6 is slidably installed on the mounting frame 1; the other end of the lever 7 is slidably connected to the slider 6.

[0048] In another embodiment of the present invention, the lever 7 is in an “L” shape, and a longer end is connected to the connecting seat 8 ; and a shorter end is connected to the slider 6 .

[0049] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the slider 6 approaches the adsorption tank body 3, it will drive the end of the lever 7 connected to the slider 6 to approach the bracket 101, and the lever 7 and the slider 6 will slide together; at this time, the lever 7 will rotate on the bracket 101, thereby driving the end of the lever 7 connected to the connecting seat 8 to approach the adsorption tank body 3, thereby driving the lifting sleeve 9 to approach the exhaust duct 302, and at this time, the lever 7 and the connecting seat 8 will slide together.

[0050] When the slider 6 moves away from the adsorption tank body 3, it will drive the end of the lever 7 connected to the slider 6 to move away from the bracket 101, and the lever 7 and the slider 6 will slide together; at this time, the lever 7 will rotate on the bracket 101, thereby driving the end of the lever 7 connected to the connecting seat 8 to move away from the adsorption tank body 3, thereby driving the lifting sleeve 9 to move away from the exhaust duct 302, and at this time, the lever 7 and the connecting seat 8 will slide together.

[0051] Since the length of the end connected to the slider 6 is shorter than the length of the end connected to the connecting seat 8, the moving distance of the slider 6 is much smaller than the moving distance of the connecting seat 8, thereby reducing the overall size of the device.

[0052] In another embodiment of the present invention, a cylinder 4 is installed on the mounting frame 1; a slide plate 5 is installed on the output end of the cylinder 4 and is slidably engaged with the mounting frame 1; a plurality of groups of inclined grooves 501 are provided on the slide plate 5; and an engaging column 601 is installed on the slider 6 and is slidably engaged with the inclined grooves 501.

[0053] In another embodiment of the present invention, the inclined grooves 501 slidably engaged with the interlocking columns 601 connected to two mutually symmetrical adsorption tank bodies 3 have opposite inclination directions, and the positions of the interlocking columns 601 in the inclined grooves 501 are opposite.

[0054] Taking the embodiment combining all the features recorded in this application as an example, when in use, the action of the cylinder 4 can drive the opening and closing mechanism and the auxiliary discharge mechanism to act; The cylinder 4 drives the slide plate 5 to slide back and forth; when the slide plate 5 moves away from the cylinder 4, the interlocking column 601 on the slider 6 connected to one group of adsorption tank bodies 3 will slide in the inclined groove 501, and the sliding direction is from the end close to the slider 6 to the end away from the sliding direction, thereby driving the slider 6 to approach the adsorption tank body 3, thereby driving the lifting sleeve 9 to approach the exhaust duct 302, during this process, exhaust and suction actions are performed in the adsorption tank body 3; and the interlocking column 601 on the slider 6 connected to another group of adsorption tank bodies 3 will slide in another inclined groove 501, and the sliding direction is from the end away from the slider 6 to the end close to the slider 6. At this time, the slider 6 will move away from the adsorption tank body 3, thereby driving the lifting sleeve 9 to move away from the exhaust duct 302, during this process, a reset action is performed in the adsorption tank body 3.

[0055] When the slide plate 5 is close to the cylinder 4, a group of adsorption tank bodies 3 perform a reset action, and the inner diameter of the other group of adsorption tank bodies 3 perform exhaust and suction actions.

[0056] By alternately performing the suction and exhaust actions and the reset action in the two mutually symmetrical adsorption tanks 3, the adsorption efficiency can be effectively improved, and the air can be prevented from being retained in the air intake pipe 2, thereby alleviating the storage pressure of the collection device.

[0057] When used, take the embodiment in which all the features recorded in this application are combined as an example.

[0058] In another embodiment of the present invention, a sealing gasket 1102 is installed on the sealing disk 1101 to increase the sealing coefficient.

[0059] Taking the embodiment combining all the features described in the present application as an example, when in use, the setting of the sealing gasket 1102 can effectively improve the air tightness between the sealing disk 1101 and the air guide groove 1001, and avoid air leakage from the side close to the exhaust duct 302 to the side far away from the exhaust duct 302 due to air compression, thereby ensuring that the air enters the exhaust duct 302 through the adsorption column 13.

[0060] A method for using the above-mentioned adsorption separation device for capturing organic components in VOCs comprises the following steps: Step 1: Install the device, check the air tightness of the device and start the device; Step 2: The boost plate 10 is driven to move toward the exhaust channel 302 by the exhaust assisting mechanism, and the sealing plate 1101 and the air guide groove 1001 cooperate with each other to increase the air circulation speed and air pressure on the adsorption column 13, thereby increasing the adsorption efficiency; at the same time, the opening and closing mechanism will first maintain the conductive state of the air inlet channel 301, so that the air can enter the adsorption tank body 3 from the air inlet pipe 2; then the opening and closing mechanism will drive the sealing block 15 to rotate to block the air inlet channel 301; Step 3: The boost plate 10 is driven away from the exhaust channel 302 by the exhaust assisting mechanism. At this time, the sealing plate 1101 and the air guide groove 1001 are disengaged from the matching state to facilitate the movement and reset of the boost plate 10. During this process, the opening and closing mechanism first keeps the air inlet channel 301 blocked to prevent air from flowing back into the air inlet pipe 2. Then, the opening and closing mechanism drives the sealing block 15 to rotate to open the air inlet channel 301. Step 4: After the device is in operation, the exhaust assisting mechanisms and the opening and closing mechanisms in the two mutually symmetrical adsorption tanks 3 cooperate with each other to alternately draw air from the air intake duct 2 into the adsorption tanks 3 to avoid air stagnation in the air intake duct 2.
