Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a device and method for treating VOCs combustion waste gas. Background Art

[0002] The combustion of VOCs (volatile organic compounds) is an effective way to treat VOCs waste gas. The combustion methods in VOCs waste gas treatment mainly include direct combustion, thermal combustion and catalytic combustion. There will be solid particles in the large amount of waste gas generated after the combustion of VOCs.

[0003] In the prior art, an exhaust gas treatment device is provided with the authorization announcement number CN114471043B. During the implementation process, the exhaust gas first enters from the air intake main pipe, enters the air intake chamber through the distributor ball and the air intake branch pipe, then enters the exhaust chamber through the air inlet and the folded channel, and then enters the treatment box through the air supply pipe. During this process, when the exhaust gas passes through the folded channel, part of the particulate matter in the exhaust gas will be intercepted and enter the dust collecting channel, and finally fall from the dust collecting channel and finally be collected by the dust exhaust pipe; after the pre-treated exhaust gas enters the treatment box It is discharged from the air intake plate, then moves upward through the one-way valve, and finally discharged upward from the exhaust hole. During this process, the exhaust gas contacts with water, and the particulate matter in the exhaust gas combines with water to settle, and is collected in the dust collecting pipe through the guidance of the dust guide plate, the dust guide top block, and the collection cover; after the exhaust gas is discharged from the exhaust hole, it flows through the filter channel, and contacts with the adsorbent in the filter channel to complete the final adsorption treatment, on the one hand, it adsorbs the remaining particulate matter in the exhaust gas, and on the other hand, it adsorbs the odor in the exhaust gas. The adsorbed gas is discharged from the exhaust pipe to complete the purification treatment of the exhaust gas. By setting up a pre-dust removal mechanism, the particulate matter in the exhaust gas can be effectively intercepted and collected, and by setting up a liquid dust removal mechanism, the exhaust gas after pre-dust removal can be contacted with water to achieve the sedimentation of the particulate matter. By setting up a filtering dust removal mechanism, the exhaust gas can be filtered and purified by adsorption. The present invention adopts a variety of exhaust gas treatment methods to perform multi-stage treatment of the exhaust gas, with high treatment efficiency and good purification effect.

[0004] It has a major disadvantage. During the process of gas being discharged from the one-way valve, the buoyancy of the gas in the water is relatively large. The gradually rising gas will push the solid that has been combined with the water to continue to move upward, thereby causing the solid particles to continue to move upward, reducing the sedimentation effect on the particles in the rising bubbles. At the same time, the gas rises in a straight line and is discharged upward. The contact time between the gas and the water is shorter, and the efficiency is lower. Summary of the invention

[0005] The embodiment of the present application provides a VOCs combustion waste gas treatment device and method, which solves the problem in the prior art that during the process of gas being discharged from a one-way valve, the buoyancy of the gas in the water is relatively large, and the gradually rising gas will push the solid that has been combined with water to continue to move upward, thereby causing the solid particles to continue to move upward, which reduces the sedimentation effect on the particles in the rising bubbles; at the same time, the gas is discharged upward in a straight line, and the contact time between the gas and the water is shorter, resulting in lower efficiency. By changing the direction of the guide member and making the guide member into a V-shape, the gas discharged from below can be separated into two parts by the guide member. Since the lower side of the guide member is inclined, the two parts of gas can gradually rise, and in the process of rising, they gradually combine with water and settle, and gradually move away from the rising direction of the gas. In the process of gradually moving away, the settled solid particles will not be unable to fall and be collected due to the impact force of the gas, thereby improving the sedimentation and collection effect of the solid particles in the gas, while increasing the flow path of the gas, increasing the reaction time of the gas and water, and improving the sedimentation effect.

[0057] A method for treating VOCs combustion waste gas comprises the following steps:

[0058] S1. Water is injected into the support cylinder through the water pipe. The water covers the uppermost end of the sedimentation component. The gas to be treated enters through the air inlet pipe and enters the dust removal cylinder. Then, the gas passes through the folded dust removal channel to initially intercept solid particles in the exhaust gas. The intercepted solid particles fall into the storage cover. After the storage cover has been used for a certain period of time, the storage cover is disassembled and its interior is cleaned;

[0059] S2, the gas after the initial filtration is transported by the delivery air pump and enters the sedimentation assembly. The gas is guided by the guide plate and rises through the one-way valve. The gas discharged from the one-way valve contacts the water inside and settles. In the process of the gas gradually rising, it is diverted through the lower end of the guide and diverted to both sides of the guide. Then it is discharged through the one-way valve 2. In the process of the gas gradually rising through the side of the guide, the settled solids fall on the guide plate, are discharged through the air passage, and fall between the support plate and the partition plate for collection;

[0060] S3, the gas discharged from the second one-way valve rises to the gas outlet and is discharged. The gas gradually rises, is discharged from the water surface, enters the odor adsorbing element, removes the odor, and is discharged through the gas outlet pipe;

[0061] S4. After long-term use, the inside of the support tube needs to be cleaned. The water inside needs to be discharged through the water pipe, and then the cleaning cover is removed to clean the solid particles and residual water in the sedimentation component.

[0062] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0063] First, by changing the direction of the guide, the guide becomes V-shaped, so that the gas discharged from the bottom can be separated into two parts by the guide. Since the lower side of the guide is inclined, the two parts of gas can gradually rise. In the process of rising, they gradually combine with water and settle, and gradually move away from the rising direction of the gas. In the process of gradually moving away, the settled solid particles will not be unable to fall and be collected due to the impact force of the gas, thereby improving the sedimentation and collection effect of the solid particles in the gas, and at the same time increasing the flow path of the gas, increasing the reaction time of the gas and water, and improving the sedimentation effect;

[0064] Secondly, by softening part of the guide, it can be deformed under the impact of the rising gas. In the process of deformation, part of the gas can be gathered to increase the residence time of the gas. At the same time, under the adsorption effect of the electromagnet, the swing plate can swing left and right to break up the larger bubbles inside. At the same time, during the swinging process, the settled solids can be swung to both sides to improve the sedimentation and collection effect.

[0065] Thirdly, by squeezing water and bubbles, they are ejected from the one-way valve 2 in a jetting manner. During the ejection process, the impact force generated can break up large bubbles, and the water flow and gas generated at the same time can break up the bubbles located above, thereby improving the sedimentation effect. At the same time, due to the process of the electromagnet adsorbing and fixing the adsorption plate, the bubbles located below the adsorption plate can be intercepted, thereby increasing the combination time of the bubbles and water. At the same time, by means of jetting, the one-way valve 2 can be prevented from being blocked by solid particles in the case of long-term use.

[0066] Fourthly, the cavity above the separation membrane in the rubber layer is inflated and expanded to seal the one-way valve 2, so that the storage space formed by the rubber layer and the support plate forms a relatively sealed space. The cavity below the separation membrane in the rubber layer is inflated and deflated. During the inflation and deflation process, the bubbles isolated inside are further broken up to improve the breaking effect. At the same time, during the continuous inflation and deflation of the cavity below the separation membrane in the rubber layer, the water and bubbles in contact with the rubber layer can be driven to shake, thereby improving the breaking effect of the bubbles.

There are multiple second one-way valves 380, which are evenly spaced along the length direction of the guide member 370. The second one-way valve 380 only allows the gas below to be transported to the top. The second one-way valve 380 is fixed on the side of the support plate 310 that is close to each other.

[0121] A method for treating VOCs combustion waste gas comprises the following steps:

[0122] S1. Water is injected into the support cylinder 110 through the water pipe 180. The water covers the uppermost end of the sedimentation assembly 300. The gas to be treated enters through the air inlet pipe 230. The gas enters the dust removal cylinder 220. Then, the gas passes through the folded dust removal channel 221 to initially intercept solid particles in the exhaust gas. The intercepted solid particles fall into the storage cover 240. After the storage cover 240 has been used for a certain period of time, the storage cover 240 is disassembled and its interior is cleaned.

[0123] S2, the gas after the initial filtration is transported by the delivery air pump 260 and enters the sedimentation assembly 300. The gas is guided by the guide plate 350 and rises through the one-way valve 1 360. The gas discharged from the one-way valve 1 360 contacts the water inside and is precipitated. In the process of the gas gradually rising, it is diverted through the lower end of the guide 370 and diverted to both sides of the guide 370, and then discharged through the one-way valve 2 380. In the process of the gas gradually rising through the side of the guide 370, the settled solids fall on the guide plate 350, are discharged through the gas passage 111, and fall between the support plate 310 and the partition plate 320 for collection;

[0124] S3, the gas discharged from the second one-way valve 380 rises to the gas outlet 340 and is discharged. The gas gradually rises, is discharged from the water surface, enters the odor adsorbing element 150, removes the odor, and is discharged through the gas outlet pipe 160;

[0125] S4. After long-term use, the inside of the support tube 110 needs to be cleaned. The water inside is discharged through the water pipe 180, and then the cleaning cover 170 is removed to clean the solid particles and residual water in the sedimentation component 300.

[0126] Compared with the prior art, by changing the orientation of the guide 370 and making it V-shaped, the gas discharged from below can be separated into two parts by the guide 370. Since the lower side of the guide 370 is inclined, the two parts of gas can gradually rise. In the process of rising, they gradually combine with water and settle, and gradually move away from the rising direction of the gas. In the process of gradually moving away, the settled solid particles will not be unable to fall and be collected due to the impact force of the gas, thereby improving the sedimentation and collection effect of the solid particles in the gas. At the same time, the flow path of the gas is increased, the reaction time of the gas and water is increased, and the sedimentation effect is improved.

[0127] Embodiment 2: During the use of embodiment 1, the gas entering the device combines with the internal water to settle, and the solid particles in the gas are collected. During the use, a large amount of gas enters from below, which brings a large buoyancy and a large rising speed. The contact between the gas and the water is short, and the natural combination and settlement between the gas entering and the water in a short time alone has a poor effect. Based on this, the solution of embodiment 1 is improved, such as Figure 7-Figure 10 As shown:

[0128] The guide member 370 includes a swing plate 371, a suction plate 372, a rubber layer 373 and a suction bag 374;

[0129] The swing plate 371 is V-shaped, and the length direction of the swing plate 371 is parallel to the length direction of the guide plate 350;

[0130] There are two adsorption plates 372 and two rubber layers 373, respectively, and they correspond to each other one by one;

[0131] The two adsorption plates 372 are respectively fixed at the two ends of the V-shaped opening of the swing plate 371, and the rubber layer 373 is fixed on the side of the adsorption plate 372 away from the swing plate 371;

[0132] The adsorption plate 372 is made of magnetic material, and the second one-way valve 380 is fixed on the rubber layer 373;

[0133] There are two adsorption capsules 374. In the initial state, the adsorption capsules 374 are V-shaped. The two adsorption capsules 374 are respectively fixed at both ends of the swing plate 371, the two adsorption plates 372 and the two rubber layers 373 in the length direction.

[0134] The adsorption capsule 374 at one end of the rubber layer 373 away from the cleaning cover 170 is in close contact with the inner wall of the support tube 110 , and the adsorption capsule 374 at one end of the rubber layer 373 close to the cleaning cover 170 is in close contact with the cleaning cover 170 ;

[0135] The adsorption capsule 374 is filled with magnetic fluid;

[0136] A magnet is fixed on one side of the cleaning cover 170 close to the inner wall cavity of the support tube 110, and a magnet is fixed on one side of the support tube 110 away from the cleaning cover 170;

[0137] It also includes power components 400, the number of which is consistent with the number of the settling components 300 and corresponds one to one;

[0138] The power assembly 400 includes an electromagnet 410;

[0139] There are two electromagnets 410 , which correspond to the two support plates 310 one by one. The electromagnets 410 are U-shaped and fixed on one side of the two support plates 310 , and are located above the feed port 311 .

[0140] When the gas passes normally, the adsorption capsule 374 is adsorbed on the magnet on the inner wall of the support tube 110 and the magnet on one side of the cleaning cover 170 through the magnetic fluid filled inside; the adsorption plate 372 is intermittently adsorbed by the electromagnets 410 on both sides, so that the swing plate 371 swings left and right. During the swinging of the swing plate 371, the adsorption capsule 374 can slide on the magnet on the inner wall of the support tube 110 and the one side of the cleaning cover 170. The swinging plate 371 that swings left and right can break up the bubbles inside. At the same time, during the swinging process, the settled solids can be swung to both sides to improve the sedimentation and collection effect.

[0141] By softening part of the guide 370, it can be deformed under the impact of the rising gas. During the deformation process, part of the gas can be gathered to increase the residence time of the gas. At the same time, under the adsorption effect of the electromagnet 410, the swing plate 371 can be swung left and right to break up the larger bubbles inside. At the same time, during the swinging process, the settled solids can be swung to both sides to improve the sedimentation and collection effect.

[0142] Embodiment 3: When the embodiment 2 is in use, the adsorption plate 372 is intermittently adsorbed by the electromagnets 410 on both sides, so that the swing plate 371 swings left and right. During the swinging process, the bubbles in the water are dispersed. However, during use, the dispersion effect on larger bubbles is poor. During the dispersion process, a long time is required to achieve the effect of turning large bubbles into multiple small bubbles, and the efficiency is poor. At the same time, when the one-way valve 2 380 is used for a long time, solid particles may pass through the inside and may be blocked by solid particles, resulting in a decrease in the gas flow rate. Based on this, the solution of the embodiment 2 is improved, such as Fig.11 As shown:

[0143] The rubber layer 373 is a hollow structure;

[0144] The power assembly 400 further includes an air pump assembly 420, wherein the air pump assembly 420 includes an air pump, and the air pump assembly 420 is fixed to a side of the support cylinder 110 away from the cleaning cover 170;

[0145] Two connecting tubes 430 are fixed to the air pump output end in the air pump assembly 420 . The ends of the two connecting tubes 430 away from the air pump pass through the support tube 110 and are connected to the inside of the two rubber layers 373 respectively.

[0146] During the use of the device, the electromagnet 410 on one side adsorbs the adsorption plate 372 that is close to it and fixes its position. During the fixing process, a storage space is formed between the rubber layer 373 and the support plate 310. The air pump in the air pump group 420 inflates the inside of the rubber layer 373, so that the bubbles and water in the storage space are ejected from the one-way valve 2 380 in the form of a jet. During the ejection process, the large bubbles are broken up, and the water flow and gas generated at the same time can break up the bubbles located above. The generated water flow and gas can also be sprayed onto the filter cover 330 to impact the attached solid particles to both sides. After that, the electromagnet 410 of the adsorbed adsorption plate 372 is powered off, and the electromagnet 410 on the other side is powered on, and the above steps are repeated.

[0147] By squeezing water and bubbles, they are ejected from the one-way valve 380 in a jet manner. During the ejection process, the impact force generated can break up large bubbles, and the water flow and gas generated at the same time can break up the bubbles located above, thereby improving the sedimentation effect. At the same time, as the electromagnet 410 adsorbs and fixes the adsorption plate 372, the bubbles located below the adsorption plate 372 can be intercepted, thereby increasing the combination time of the bubbles and water. At the same time, by means of spraying, the one-way valve 380 can be prevented from being blocked by solid particles during long-term use.

[0148] Embodiment 4: During the use of embodiment 3, the gas and water are ejected by squeezing through the expansion of the rubber layer 373. However, during the use, the bubbles in the storage space between the rubber layer 373 and the support plate 310 can be further dispersed to combine with the water inside to improve the sedimentation effect. Based on this, the solution of embodiment 2 is improved, such as Figure 12-14 As shown:

[0149] The sedimentation assembly 300 further includes a separation membrane 375, the length direction of which is parallel to the length direction of the swing plate 371, the separation membrane 375 is located in the cavity of the rubber layer 373, the separation membrane 375 is fixed to the inner wall of the cavity of the rubber layer 373, and the separation membrane 375 separates the cavity of the rubber layer 373 into two cavities that are not connected to each other;

[0150] The air pump group 420 has two air pumps, and the connecting pipes 430 at the output ends of the two air pumps are respectively connected to the two cavities separated by the separation membranes 375 in the two rubber layers 373;

[0151] The cavities in the two rubber layers 373 above the separation membrane 375 are communicated with the same air pump, and the cavities in the two rubber layers 373 below the separation membrane 375 are communicated with the same air pump.

[0152] When the electromagnets 410 on both sides intermittently adsorb and fix the adsorption plate 372, the air pump in the air pump group 420 is controlled to inflate the cavity above the partition membrane 375 in the rubber layer 373, and expand to seal the one-way valve 380. Then, the cavity below the partition membrane 375 in the rubber layer 373 is inflated and deflated. During the inflation and deflation process, the bubbles isolated inside are further broken up. After the breaking up is completed, the cavity above the partition membrane 375 in the rubber layer 373 is deflated, and the cavity below the partition membrane 375 in the rubber layer 373 is inflated to spray out the bubbles and water inside.

[0153] The cavity above the separation membrane 375 in the rubber layer 373 is inflated and expanded to seal the one-way valve 380, so that the storage space formed by the rubber layer 373 and the support plate 310 forms a relatively sealed space. The cavity below the separation membrane 375 in the rubber layer 373 is inflated and deflated. During the inflation and deflation process, the bubbles isolated inside are further broken up to improve the breaking effect. At the same time, during the continuous inflation and deflation of the cavity below the separation membrane 375 in the rubber layer 373, the water and bubbles in contact with the rubber layer 373 can be driven to shake, thereby improving the breaking effect of the bubbles.

[0154] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

A method for treating VOCs combustion waste gas, characterized in that: A VOCs combustion waste gas treatment device according to any one of claims 1 to 5 is provided, comprising the following steps: S1. Water is injected into the support cylinder (110) through the water delivery pipe (180), and the water covers the uppermost end of the sedimentation assembly (300). Gas to be treated enters through the air inlet pipe (230), and the gas enters the dust removal cylinder (220). The gas then passes through the folded dust removal channel (221) to initially intercept solid particles in the exhaust gas. The intercepted solid particles fall into the storage cover (240). After the storage cover (240) has been used for a certain period of time, the storage cover (240) is removed and the interior thereof is cleaned; S2, the gas after the initial filtration is transported by the transporting air pump (260) and enters the sedimentation assembly (300). The gas is guided by the guide plate (350) and rises through the one-way valve (360). The gas discharged from the one-way valve (360) contacts the water inside and is precipitated. In the process of the gas gradually rising, the gas is diverted through the lower end of the guide (370) and diverted to the two sides of the guide (370). Then, the gas is discharged through the one-way valve (380). In the process of the gas gradually rising through the side of the guide (370), the settled solids fall on the guide plate (350), are discharged through the gas passage (111), and fall between the support plate (310) and the partition plate (320) for collection; S3, the gas discharged from the second one-way valve (380) rises to the gas outlet (340) and is discharged. The gas gradually rises, is discharged from the water surface, enters the odor adsorbing element (150), removes the odor, and is discharged through the gas outlet pipe (160); S4. After long-term use, the inside of the support tube (110) needs to be cleaned. The water inside is discharged through the water pipe (180), and then the cleaning cover (170) is removed to clean the solid particles and residual water in the sedimentation assembly (300).
