Description

Technical Field

[0001] The present application relates to the technical field of VOC waste gas treatment, and in particular to a spray scrubbing tower for filtering high-viscosity VOC gas. Background Art

[0002] VOC is the abbreviation of volatile organic compounds. In the ordinary sense, VOC refers to volatile organic compounds, but in the environmental sense, it refers to a class of active volatile organic compounds, that is, the type of volatile organic compounds that can cause harm.

[0003] In the prior art, the Chinese utility model patent with the authorization announcement number CN218459084U discloses "a spray washing tower for treating VOC waste gas", including a base, a spray washing tower body is installed on the top of the base, and a partition is installed at the bottom of the inside of the spray washing tower body, and a slow flow seat is installed on the top of the partition. The utility model is provided with a partition, and during use, the inside of the spray washing tower body can be divided into two spray washing areas by the partition, and the VOC waste gas can be diverted in cooperation with the two groups of VOC waste gas inlet pipes, thereby avoiding the phenomenon of low treatment efficiency caused by concentrated gas injection, and at the same time, by providing a first spray pipe, a second spray pipe and a third spray pipe, the spray range of the VOC waste gas can be increased, so that the VOC waste gas can be fully washed, and at the same time, by providing a slow flow seat and a slow flow cavity, the flow direction of the treated gas can be changed multiple times to reduce its flow rate, so that it can fully contact with the adsorption purification layer.

[0004] However, in actual use, there are still some deficiencies in the design of the spray washing tower. Take the installation and disassembly of the filter plate as an example. Although the existing spray washing tower design facilitates the installation or disassembly of the filter plate through the connection and separation of the installation groove, the first magnetic tile, the mounting block and the second magnetic tile, such a design still requires the use of a side door to operate, which means that the sealing requirements for the side door are high. Once the seal is not tight, it may cause exhaust gas leakage, which not only affects the treatment effect, but may also cause secondary pollution to the environment.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0024] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0025] The present application discloses a spray scrubber for filtering high-viscosity VOC gas. Figure 1-Figure 3 A spray scrubber for filtering high-viscosity VOC gas comprises a scrubber body 1, a cover door 4 is threadedly mounted on the top of the scrubber body 1, a handle 5 is fixed on the top of the cover door 4, an air outlet pipe 25 is also fixed on the top surface of the cover door 4, three support legs 2 are fixed on the outer wall of the scrubber body 1 and are equidistantly distributed in a circular shape, and a water outlet 3 is also fixed at the bottom end of the scrubber body 1;

[0026] The outer wall of the washing tower body 1 is also fixed with two symmetrically distributed water inlet pipes 7 and air inlet pipes 6, and the two water inlet pipes 7 are both threadedly mounted with nozzles 12 inside the washing tower body 1;

[0027] It also includes a connecting piece 9, both sides of which are connected with a filter screen 10 through a rotating shaft. The inner wall of the washing tower body 1 is also fixed with a first fixing ring 8 and a second fixing ring 23 respectively. The filter screen 10 is placed above the first fixing ring 8, and the top surface of the second fixing ring 23 is placed with an adsorption purification layer 24. When in use, firstly, the two water inlet pipes 7 are connected to the water pump by a hose, and then the high-viscosity VOC gas is introduced into the washing tower body 1 through the air inlet pipe 6. During the rising process of the gas inside the washing tower body 1, it will contact with the washing liquid sprayed by the two nozzles 12. The washing liquid can effectively reduce the viscosity of the gas and preliminarily wash and remove the harmful substances therein. Subsequently, the gas continues to rise and continues to rise into the adsorption purification layer 24. The adsorption purification layer 24 is composed of adsorption materials such as activated carbon, which can effectively adsorb harmful substances in the gas and further purify the gas. The adsorption purification layer 24 is placed on the top surface of the second fixing ring 23 for easy replacement and cleaning. Finally, the gas after washing, filtering and adsorption purification passes through the outlet The air pipe 25 discharges the washing tower body 1. During the whole process, the supporting legs 2 of the washing tower body 1 can maintain its stability to prevent the washing tower from shaking during operation. In addition, a water outlet 3 is provided at the bottom end of the washing tower body 1 to facilitate the discharge of waste water generated during the washing process. The waste water can be connected to the waste water treatment equipment through a pipeline for further treatment and then discharged after meeting the environmental protection standards. After the discharge is completed, the cover door 4 can be removed from the washing tower body 1 counterclockwise, and then the adsorption purification layer 24 is taken out. When the two filters 10 are taken out, since the top surface of the connecting piece 9 is fixed with a handle 11, the handle 11 can be pulled upward to make the two filters 10 flip around the connecting piece 9 as the center. At this time, the two filters 10 can be removed from the inside of the washing tower body 1 for cleaning or replacement, and the filter 10 can be quickly installed or disassembled without the help of the side door, which not only saves the manufacturing cost, but also increases the sealing of the washing tower body 1, avoids the leakage of exhaust gas, and prevents secondary pollution to the environment.

[0028] Reference Figure 1 and Figure 3The outer wall of the cover door 4 is fixed with two symmetrically distributed limit rods 21, and one end of the two limit rods 21 is fixed with a limit plate 22. The outer wall of the washing tower body 1 is located below the limit rod 21 and is fixed with a fixing plate 13. The two fixing plates 13 are penetrated with two symmetrically distributed guide rods 14, one end of the guide rod 14 is fixed with a fixing plate 15, and the other end is threaded with a nut 16. The outer wall of the guide rod 14 is also sleeved with a reset spring 17, and the reset spring 17 is located between the nut 16 and the fixing plate 13. The top surfaces of the two fixing plates 15 are connected with a mounting plate 18 through a rotating shaft, and the mounting plate 18 is provided with a first limit groove 19 and a second limit groove 19. The first limiting groove 20 is connected with the second limiting groove 20; when in use, the mounting piece 18 can be pulled upward and flipped over so that the first limiting groove 19 passes through the limiting piece 22, and at the same time, the nut 16 will squeeze the reset spring 17 to shrink it. When the first limiting groove 19 passes through the limiting piece 22, the mounting piece 18 can be loosened. At this time, the reset spring 17 will push the nut 16 to move downward. At this time, the limiting piece 22 will be hung on the limiting rod 21, and at the same time, the limiting piece 22 will limit the second limiting groove 20 to prevent it from sliding, thereby increasing the stability of the cover door 4 and preventing it from loosening easily, thereby further increasing the sealing of the washing tower body 1.

[0029] Reference Figure 3 The diameter of the first limiting groove 19 is larger than the diameter of the limiting plate 22, and the diameter of the second limiting groove 20 is consistent with the diameter of the limiting rod 21, and the diameter of the second limiting groove 20 is smaller than the diameter of the limiting plate 22; it is convenient for the first limiting groove 19 to pass through the limiting plate 22, and the limiting plate 22 can also be used to limit the second limiting groove 20 to prevent it from slipping.

[0030] Reference Figure 2 The inner wall of the washing tower body 1 is coated with an anti-corrosion coating to resist the corrosion effect of high-viscosity VOC gas on the inner wall of the washing tower, thereby extending the service life of the washing tower.

[0031] Reference Figure 2 The filter 10 is made of high temperature resistant and corrosion resistant materials and can effectively filter particulate matter in high viscosity VOC gas.

[0032] Reference Figure 2 The adsorption purification layer 24 is made of activated carbon or other materials with strong adsorption capacity; it can effectively adsorb harmful components in high-viscosity VOC gas and improve the gas purification effect.

[0033] The implementation principle of a spray scrubber for filtering high-viscosity VOC gas in the embodiment of the present application is as follows: when in use, firstly, two water inlet pipes 7 are connected to a water pump by a hose, and then the high-viscosity VOC gas is introduced into the interior of the scrubber body 1 through the air inlet pipe 6. During the rising process of the gas inside the scrubber body 1, it will contact with the scrubbing liquid sprayed by the two nozzles 12. The scrubbing liquid can effectively reduce the viscosity of the gas and preliminarily wash and remove the harmful substances therein. Subsequently, the gas continues to rise and continues to rise into the adsorption purification layer 24. The adsorption purification layer 24 is composed of adsorption materials such as activated carbon, which can effectively adsorb harmful substances in the gas and further purify the gas. The adsorption purification layer 24 is placed on the top surface of the second fixed ring 23 for easy replacement and cleaning. Finally, the gas after washing, filtering and adsorption purification is discharged from the scrubber body 1 through the air outlet pipe 25. During the whole process, the support legs 2 of the scrubber body 1 can maintain its stability to prevent the scrubber from shaking during operation.

[0034] In addition, a water outlet 3 is provided at the bottom of the washing tower body 1 to facilitate the discharge of wastewater generated during the washing process. The wastewater can be connected to the wastewater treatment equipment through a pipeline for further treatment and then discharged after meeting environmental protection standards;

[0035] After the discharge is completed, the cover door 4 can be removed from the washing tower body 1 by turning it counterclockwise, and then the adsorption purification layer 24 can be taken out. When the two filters 10 are taken out, since the top surface of the connecting piece 9 is fixed with a handle 11, the handle 11 can be pulled upwards to make the two filters 10 flip around the connecting piece 9. At this time, the two filters 10 can be removed from the inside of the washing tower body 1 for cleaning or replacement, and the filters 10 can be quickly installed or disassembled without the help of the side door, which not only saves manufacturing costs, but also increases the sealing of the washing tower body 1, avoids exhaust gas leakage, and prevents secondary pollution to the environment.
