Description

Technical Field

[0001] The present invention relates to the technical field of organic waste gas treatment, and specifically relates to an organic waste gas purification and treatment device. Background Art

[0002] Organic waste gas refers to the general term for waste gas containing organic matter generated during industrial production processes. In order to treat organic waste gas, a variety of waste gas treatment technologies have been developed, such as adsorption method, condensation method, combustion method, catalytic oxidation method, plasma method, etc. Among them, the adsorption method mainly uses activated carbon to adsorb the odor and impurities in the waste gas. The plasma method is to pass the waste gas into a strong electric field generated by a cathode plate and an anode plate. Under the action of the strong electric field, gas molecules in the air will be ionized to form plasma, and the plasma also contains a large number of active free radicals (such as hydroxyl free radicals, ozone, etc.). These active free radicals have extremely strong oxidizing properties and can chemically react with organic molecules in the waste gas to oxidize them into harmless substances;

[0003] Different industrial production processes have different production cycles, such as start-up, stable operation, shutdown and other stages. During these stages, the emission concentration and rate of the waste gas will change accordingly. For example, during the start-up stage, due to processes such as equipment preheating and raw material input, it may lead to a temporary increase in the emission concentration and rate of the waste gas. When high-concentration waste gas passes through the activated carbon and the electric field at a relatively fast rate, the time for the activated carbon and the electric field to purify and treat the waste gas is limited, resulting in the activated carbon and the electric field being unable to fully purify and treat the waste gas. Most organic waste gas purification and treatment devices are not easy to adjust the purification intensity according to the transmission concentration and rate of the waste gas, which affects the waste gas treatment effect. Summary of the Invention

[0019] Furthermore: A support shell is fixed on the top of the base. A top cover is detachably fixed on the top of the support shell. A side cover is detachably fixed on one side of the support shell.

[0020] Furthermore: The transmission mechanism includes: It should be noted that the term "传动连接" in the original text is not a standard English expression. It is recommended to check the specific mechanical or technical meaning in the relevant field to ensure the accuracy of the translation. Here, a more general "connected" is used first, and you can adjust it according to the actual situation.

[0021] A fixed seat is fixed on the top of the base, and one end and the top of the fixed seat are respectively provided with a connecting shaft 1 and a connecting shaft 2 which are meshed and driven with each other;

[0022] Gear one, fixedly connected to connecting shaft two;

[0023] The gear ring is meshed with the gear one for transmission, and the gear ring is fixedly connected to the bottom surface of the sleeve.

[0024] Furthermore, the outer sides of the connecting shaft 1 and the connecting shaft 2 are fixed with gears 2 that mesh with each other, the connecting shaft 1 is detachably fixedly connected to the shaft rod at the corresponding position, and a one-way bearing is sleeved between the connecting shaft 1 and the gear 2.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. By conveying the external organic waste gas to the inside of the square tube through the intake pipe and the intake hood, the anode plate on the bottom of the mobile box and the cathode plate on the bottom of the square tube are energized in advance, and a strong electric field is generated between the cathode plate and the anode plate, so as to facilitate the plasma purification of the organic waste gas entering the electric field. The organic waste gas after plasma treatment is then conveyed to the adsorption box inside the sleeve. The activated carbon contained in the adsorption box can absorb the odor impurities in the organic waste gas, so as to achieve the effect of further purifying the waste gas. The purified waste gas is conveyed from the mesh hole on the adsorption box through the arc hole to the inside of the exhaust pipe, and finally discharged from the exhaust pipe.

[0027] 2. By installing a VOC gas sensor in the prior art inside the air intake hood, the VOC gas sensor can detect the concentration of exhaust gas passing through the air intake hood. When the exhaust gas concentration is detected to be high, both motors drive the shaft to rotate to rotate the winding wheel on the shaft (the winding wheel includes winding wheel 1 and winding wheel 2), the winding wheel at the top of the casing rotates to release the traction rope (the traction rope includes traction rope 1 and traction rope 2), and the winding wheel at the bottom of the casing rotates to reel in the traction rope, so that the moving box moves down to the inside of the square tube, and the moving box 2 moves down to the inside of the square plate, refer to the instruction manual Figure 8 Part of the exhaust gas entering the square tube passes through the space between the bottom of the moving box 1 and the square tube, and the other part of the exhaust gas enters the interior of the square plate from one end of the moving box 1 and passes through the bottom of the moving box 2;

[0028] An electric field 1 is generated between the anode plate on the bottom surface of the first moving box and the first cathode plate on the inner bottom surface of the square tube, and an electric field 2 is generated between the second cathode plate on the bottom surface of the second moving box and the anode plate on the top surface of the first moving box. The electric field 1 and the electric field 2 can respectively perform plasma treatment on two separate high-concentration waste gases. At the same time, after the first moving box and the second moving box move downward, the distance between the cathode plates (including the first cathode plate and the second cathode plate) and the anode plate decreases, so as to increase the intensity of the electric field while the concentration of the waste gas increases, which is beneficial to improving the purification effect of plasma treatment of organic waste gas.

[0029] 3. By setting the diameter of the first winding wheel to be twice the diameter of the second winding wheel, so that after each rotation of the first winding wheel and the second winding wheel, the length of the first traction rope wound or released by the first winding wheel is twice the length of the second traction rope. When using the rotation of the winding wheel to wind and release the traction rope to move the first moving box and the second moving box downward, the downward distance of the second moving box is twice the downward distance of the first moving box, so that the distance between the bottom surface of the first moving box and the inner bottom surface of the square tube is the same as the distance between the bottom surface of the second moving box and the top surface of the first moving box. After the first moving box and the second moving box move downward, the distance between the cathode plates and the anode plate at different positions is the same, so that the same electric field intensity is generated inside the square tube and the C-shaped plate to treat high-concentration organic waste gas.

[0030] 4. By moving the first moving box and the second moving box downward, the high-concentration waste gas is separated and passes through different electric fields. And the intensity of the electric field increases after the first moving box and the second moving box move downward, improving the effect of plasma treatment of high-concentration waste gas. And the waste gas discharged from the square tube and the C-shaped plate can be introduced into the corresponding adsorption boxes. When facing high-concentration waste gas, two adsorption boxes filled with activated carbon can be used to adsorb and purify the waste gas at the same time, which is convenient for the activated carbon to fully adsorb and filter the high-concentration waste gas, and improves the efficiency of plasma treatment and adsorption treatment of high-concentration waste gas;

[0031] When the rate of the external waste gas transported into the square tube is relatively large, the two first cathode plates on the inner bottom surface of the square tube, the two anode plates on the top and bottom surfaces of the first moving box, and the two second cathode plates on the bottom surface of the second moving box can be energized, so that a long-distance electric field is generated inside the entire square tube and the C-shaped plate, so that the waste gas with a faster moving rate can be in the electric field for a long time for purification treatment, which is convenient for fully performing plasma treatment on the waste gas with a relatively large moving rate;

[0032] When high-concentration and high-speed exhaust gas is transported to the inside of the square tube, all cathode plates and anode plates can be opened to generate a long-distance electric field, and mobile box one and mobile box two can be moved down to shorten the distance between the cathode plate and the anode plate. This can enhance the intensity of the electric field plasma treatment of organic waste gas, achieve long-distance strong electric field plasma treatment of the exhaust gas, and then the treated exhaust gas is adsorbed and treated by two activated carbon adsorption boxes, thereby automatically adjusting the intensity of the electric field and the number of activated carbon adsorption boxes involved in the adsorption of the exhaust gas according to the transmission concentration and rate of the exhaust gas, so as to adaptively control the intensity of the adsorption purification.

Detailed implementation mode

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0044] Example 1, please refer to Figure 1 - Fig. 9, in the embodiment of the present invention, an organic waste gas purification and treatment device includes a casing 100. The casing 100 includes a base 110. A plasma treatment module 200 is arranged inside the casing 100. The plasma treatment module 200 includes a square tube 210 fixedly connected to the casing 100. A first moving box 220 is slidably connected to the top of the square tube 210. A U-shaped plate 230 is fixed to the top surface of the square tube 210. A second moving box 240 is slidably connected to the top of the U-shaped plate 230. A traction mechanism 300 for driving the first moving box 220 and the second moving box 240 to move up and down is arranged inside the casing 100. The traction mechanism 300 includes two first support seats 310 and two second support seats 320. A shaft rod 330 is rotatably arranged between the two first support seats 310 and between the two second support seats 320. A first winding wheel 340 and a second winding wheel 350 are fixed to both ends of the shaft rod 330. A first traction rope 341 fixed to the second moving box 240 is wound and fixed on the outside of the first winding wheel 340. A second traction rope 351 fixed to the first moving box 220 is wound and fixed on the outside of the second winding wheel 350. An exhaust pipe 400 is arranged at one end of the plasma treatment module 200. An adsorption module 500 is rotatably sleeved on the outside of the exhaust pipe 400. The adsorption module 500 includes a sleeve 510. A plurality of adsorption boxes 520 are detachably inserted and fixed in the sleeve 510 at equal angles in a ring shape. Among them, a transmission mechanism 600 for driving the sleeve 510 to rotate is arranged at one end of a shaft rod 330.

[0045] Specifically, by slidably connecting a first moving box 220 and a second moving box 240 above the square tube 210 for plasma treatment of waste gas, when high-concentration organic waste gas is introduced into the square tube 210, the shaft rod 330 drives the winding wheels at different positions to wind and release the traction ropes, so that the first moving box 220 moves into the square tube 210, and the second moving box 240 moves into the U-shaped plate 230, thereby realizing that the high-concentration waste gas is divided into two streams and passes through the enhanced electric fields at different positions respectively, improving the effect of electric field plasma treatment of waste gas. In addition, both streams of waste gas can be introduced into the adsorption boxes 520 filled with activated carbon, realizing the adsorption and filtration of high-concentration waste gas by using a plurality of activated carbon adsorption boxes 520, which is beneficial to improving the effect of waste gas filtration and adsorption, and facilitating the automatic adjustment of the electric field intensity and the number of activated carbon adsorption boxes 520 participating in adsorbing waste gas according to the concentration of waste gas to adaptively control the adsorption and purification intensity, achieving the effect of fully purifying waste gas.

[0046] Such as Figure 4 And Fig. 9As shown, in this embodiment, two first cathode plates 211 are fixedly embedded in the inner bottom surface of the square tube 210, two anode plates 221 are fixedly embedded in both the inner bottom surface and the outer bottom surface of the first moving box 220, and two second cathode plates 241 are fixedly embedded in the bottom surface of the second moving box 240. Thus, an electric field can be formed between the first cathode plates 211 and the second cathode plates 241 and the corresponding anode plates 221 to perform plasma treatment on the waste gas. Moreover, as the cathode plates at different positions approach the anode plates 221, the electric field strength can be enhanced, improving the effect of purifying high-concentration waste gas.

[0047] As Figure 3 and Figure 4 shown, in this embodiment, an air inlet hood 250 is fixedly connected and communicated with one end of the square tube 210. A VOC gas sensor 251 is fixedly installed inside the air inlet hood 250. The VOC gas sensor 251 can detect the concentration of the waste gas, which is a prior art and the specific working principle will not be elaborated. A sealing plate 231 is fixed to one end of the C-shaped plate 230 close to the air inlet hood 250 to prevent the waste gas entering the inside of the C-shaped plate 230 from leaking from the position of the sealing plate 231, so that the waste gas is conveyed towards the adsorption box 520. One end of the air inlet hood 250 is fixedly connected and communicated with an air inlet pipe 252 that is communicated with the external waste gas pipeline.

[0048] As Figure 3 and Figure 4 shown, in this embodiment, the first support base 310 is fixedly connected to the C-shaped plate 230, and the second support base 320 is fixedly connected to the base 110. Motors 360 for driving the shaft rod 330 to rotate are fixedly installed on the outer sides of one first support base 310 and one second support base 320. The motor 360 drives the shaft rod 330 above the housing 100 to rotate the winding wheel to release the traction rope, and the motor 360 drives the shaft rod 330 below the housing 100 to rotate the winding wheel to wind up the traction rope, so as to realize pulling the first moving box 220 and the second moving box 240 downward, realizing separating the waste gas into two streams for purification respectively, and enhancing the strength of the electric field at the same time.

[0049] As Figure 1 shown, in this embodiment, a support shell 120 is fixedly installed on the top of the base 110. A top cover 130 is detachably fixed to the top of the support shell 120, and a side cover 140 is detachably fixed to one side of the support shell 120. Opening the top cover 130 and the side cover 140 is convenient for overhauling the device, and opening the side cover 140 is also convenient for adding and replacing the adsorption box 520 into the sleeve 510.

[0050] As Figure 4 and Figure 5As shown, in this embodiment, a exhaust pipe 410 is fixedly connected to the top of the exhaust stack 400. A support column 420 fixedly connected to the base 110 is fixed to the bottom of the exhaust stack 400. An arc-shaped hole 430 is formed through the outside of the exhaust stack 400. The waste gas after plasma treatment from one end of the square pipe 210 and the U-shaped plate 230 will enter the adsorption box 520 for adsorption treatment. The waste gas after being adsorbed by the adsorption box 520 passes through the mesh holes 521 on the adsorption box 520 and is then transported to the inside of the exhaust stack 400 from the position of the arc-shaped hole 430, and finally is discharged from the exhaust pipe 410 above the exhaust stack 400 to the next organic waste gas treatment station for treatment.

[0051] As Figure 7 shown, in this embodiment, a plurality of arc-shaped holes 511 are formed through the inside of the sleeve 510 at equal angles in a ring shape, which is convenient for inserting and installing two adsorption boxes 520 inside each arc-shaped hole 511. Two limiting blocks 512 are rotatably connected to both ends of the bottom of the arc-shaped hole 511. When it is necessary to disassemble the adsorption box 520 with saturated adsorption inside the sleeve 510, open the side cover 140, rotate and pull the two limiting blocks 512 on the bottom surface of the sleeve 510 away from the adsorption box 520, and then insert the new adsorption box 520 from the top of the arc-shaped hole 511 downwards, which is convenient to replace and squeeze the saturated adsorption box 520 onto the base 110. And if the adsorption box 520 above the arc-shaped hole 511 is not saturated, but the adsorption box 520 below the arc-shaped hole 511 is already saturated, the adsorption box 520 above the arc-shaped hole 511 can be pushed down to replace it to the position below the arc-shaped hole 511 for continuous use.

[0052] In this embodiment, mesh holes 521 are formed on both sides of the adsorption box 520, which is convenient for the waste gas after activated carbon adsorption treatment to be transmitted to the inside of the exhaust stack 400 through the adsorption box 520. Rubber strips 522 are sleeved and fixed on the outer edges of the adsorption box 520, so that the adsorption box 520 inserted into the arc-shaped hole 511 will not easily fall out of the arc-shaped hole 511.

[0053] As Figure 3 shown, in this embodiment, a baffle 523 is detachably fixed to the top of the adsorption box 520. Opening the baffle 523 allows activated carbon to be filled into the adsorption box 520.

[0054] Embodiment 2, on the basis of Embodiment 1, for automatically replacing the adsorption box 520 filled with activated carbon with saturated adsorption.

[0055] As Figure 4 and Figure 6As shown in the figure, in this embodiment, the transmission mechanism 600 includes a fixed seat 610 fixed to the top of the base 110. One end and the top of the fixed seat 610 are respectively rotatably provided with a first connecting shaft 611 and a second connecting shaft 612 that are meshed and driven with each other. A first gear 620 is fixedly connected to the top of the second connecting shaft 612. A toothed ring 630 that is meshed and driven with the first gear 620 is fixedly connected to the bottom surface of the sleeve 510. Wherein, gears two that are meshed and driven with each other are fixedly provided on the outer sides of the first connecting shaft 611 and the second connecting shaft 612. The first connecting shaft 611 is detachably and fixedly connected to the corresponding position shaft rod 330. A one-way bearing is sleeved between the first connecting shaft 611 and the gear two.

[0056] Specifically, the shaft rod 330 at the bottom of the casing 100 is denoted as the lower shaft rod 330 here. When the lower shaft rod 330 drives the winding wheel to rotate and wind the traction rope, the lower shaft rod 330 drives the first connecting shaft 611 to rotate. The first connecting shaft 611 idles on the gear two under the action of the one-way bearing. Because the purpose of the lower shaft rod 330 driving the winding wheel to rotate and wind the traction rope (including the first traction rope 341 and the second traction rope 351) is to lower the first moving box 220 and the second moving box 240 to deal with high-concentration waste gas. After the high-concentration waste gas is transmitted to the adsorption box 520 position of the sleeve 510 through one end of the square pipe 210 and the C-shaped plate 230, the adsorption box 520 is basically in a saturated state because of the purification work of the high-concentration waste gas;

[0057] After the high-concentration waste gas is treated, when the lower shaft rod 330 drives the winding wheel to rotate and release the traction rope to make the first moving box 220 and the second moving box 240 return to the initial position, the lower shaft rod 330 drives the first connecting shaft 611 to rotate again. At this time, the first connecting shaft 611 drives the two meshed gears two to rotate, so that the second connecting shaft 612 drives the first gear 620 to rotate. The first gear 620 drives the toothed ring 630 to rotate. The toothed ring 630 drives the sleeve 510 to rotate outside the exhaust pipe 400, and transfers the adsorption boxes 520 at the remaining positions inside the sleeve 510 to one end of the square pipe 210 and the C-shaped plate 230 for standby, realizing the automatic replacement of the saturated adsorption box 520. Because the first connecting shaft 611 and the lower shaft rod 330 are detachably installed and fixed, when the adsorption box 520 does not need to be replaced for a long time, the first connecting shaft 611 and the lower shaft rod 330 can be disassembled and separated, so that the sleeve 510 no longer rotates with the rotation of the lower shaft rod 330, realizing the effect of using the adsorption box 520 for a long time.

[0058] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
