Description

Technical Field

[0001] This utility model relates to the field of industrial waste gas treatment technology, specifically to an industrial oil fume tar odor deodorization device. Background Technology

[0002] During industrial production, a large amount of industrial fumes are emitted, which contain tar and various odorous substances. If these waste gases are emitted directly without effective treatment, they will cause serious pollution to the atmospheric environment, affect the quality of life of surrounding residents, and may also violate relevant environmental protection regulations.

[0003] Existing industrial fume treatment equipment has many problems. On the one hand, it is not effective in removing tar, which tends to accumulate inside the equipment, affecting its normal operation and shortening its service life. On the other hand, it has a single treatment method for removing odors, which is difficult to deal with complex and varied odor components, resulting in low deodorization efficiency and failing to meet increasingly stringent environmental protection requirements.

[0004] Therefore, there is a need for an industrial oil fume tar odor removal device to solve the problems of poor tar removal effect and limited odor treatment methods in existing oil fume treatment devices. Utility Model Content

[0005] The purpose of this invention is to provide an industrial oil fume tar odor deodorization device to solve the problems of poor tar removal effect and limited odor treatment methods in existing oil fume treatment devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an industrial oil fume tar odor deodorization device, comprising a treatment box, wherein an inlet pipe and an outlet pipe are fixedly connected to the outer walls on both sides of the treatment box, two parallel partitions are fixedly connected inside the treatment box, an openable and closable inspection door is provided at the front end of the treatment box, and a pretreatment mechanism, a tar removal component and an odor removal device are provided inside the treatment box;

[0007] The pretreatment mechanism includes a sedimentation tank, a circulating pump, and a frame. The sedimentation tank is fixedly connected to the left side of the bottom surface inside the treatment tank. The circulating pump is installed on the outer wall of the rear end of the treatment tank corresponding to the sedimentation tank. The frame is fixedly connected to the top surface inside the treatment tank and located directly above the sedimentation tank. A spray pipe is installed inside the frame. A connecting pipe is fixedly connected between the output end of the circulating pump and the input end of the spray pipe.

[0008] It should be noted in the solution that the tar removal assembly includes an inclined block, a channel, a collection box, and two nozzles. The inclined block is fixedly connected to the center of the bottom surface inside the processing box. Two parallel electrode plates are installed between the top surface of the inclined block and the top surface inside the processing box. A condenser pipe is installed between the top surface of the inclined block and the top surface inside the processing box. The channel is opened through the bottom surface of the processing box and is close to the lower side of the inclined block. The collection box is fixedly connected to the bottom surface of the processing box. Both nozzles are installed on the top surface inside the processing box.

[0009] It is worth noting that the odor removal device includes a filter layer, a photocatalytic oxidation layer, a UV lamp, and a plasma purification layer. The filter layer, the photocatalytic oxidation layer, and the plasma purification layer are all installed on the right side inside the treatment box and are evenly distributed. The UV lamp is installed on the top surface inside the treatment box and faces the photocatalytic oxidation layer.

[0010] Furthermore, it should be noted that the connecting pipe is fixedly connected to the two nozzles by the same water distribution pipe, and channels are opened through the sides of both partitions.

[0011] In a preferred embodiment, the input end of the circulating pump is connected to the sedimentation tank, and solenoid valves are installed on both the connecting pipe and the water distribution pipe.

[0012] In a preferred embodiment, the collection box is connected to the through groove, and the output ends of the two nozzles correspond one-to-one with the two electrode plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The system sprays oil fumes through spray pipes, removing some particulate matter and soluble odor substances from the fumes. The system also uses electrode plates and condenser pipes to adsorb and condense the tar in the oil fumes, liquefying it and allowing it to flow into a collection box for collection. The system further cleans the electrode plates through spray pipes, achieving separation of tar from the fumes and effectively avoiding the problem of poor tar removal in oil fume treatment equipment.

[0015] 2. By combining the filter layer, photocatalytic oxidation layer and plasma purification layer, the flue gas is deodorized and odor-removed. It can comprehensively treat different types of odor substances, with high deodorization efficiency, effectively avoiding the problem of single odor treatment methods in oil fume treatment equipment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a processing box 1. The outer walls on both sides of the processing box 1 are respectively fixedly connected to a smoke inlet pipe 2 and a smoke outlet pipe 3. The processing box 1 has two parallel partitions 4 fixedly connected inside. The front end of the processing box 1 is provided with an openable and closable maintenance door 10. The processing box 1 is provided with a pretreatment mechanism 5, a tar removal component 6 and an odor removal device 7.

[0023] The pretreatment unit 5 includes a sedimentation tank 51, a circulating pump 52, and a frame 53. The sedimentation tank 51 is fixedly connected to the left side of the bottom surface inside the treatment box 1. The circulating pump 52 is installed on the outer wall of the rear end of the treatment box 1 corresponding to the sedimentation tank 51. The frame 53 is fixedly connected to the top surface inside the treatment box 1 and is located directly above the sedimentation tank 51. A spray pipe 54 is installed inside the frame 53. A connecting pipe 55 is fixedly connected between the output end of the circulating pump 52 and the input end of the spray pipe 54.

[0024] Specifically, after the fumes enter the treatment box 1 through the smoke inlet pipe 2, the circulation pump 52 sends the washing liquid in the sedimentation tank 51 into the spray pipe 54 through the connecting pipe 55. The spray pipe 54 sprays the fumes to remove some particulate matter and soluble odor substances from the fumes. The sprayed washing liquid falls into the sedimentation tank 51 for sedimentation, thus realizing the recycling of the washing liquid.

[0025] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the tar removal assembly 6 includes an inclined block 61, a channel 64, a collection box 65, and two nozzles 66. The inclined block 61 is fixedly connected to the center of the bottom surface inside the processing box 1. Two parallel electrode plates 62 are installed between the top surface of the inclined block 61 and the top surface inside the processing box 1. A condenser pipe 63 is installed between the top surface of the inclined block 61 and the top surface inside the processing box 1. The channel 64 is opened through the bottom surface of the processing box 1 and is close to the lower side of the inclined block 61. The collection box 65 is fixedly connected to the bottom surface of the processing box 1. Both nozzles 66 are installed on the top surface inside the processing box 1.

[0026] Specifically, the sprayed flue gas passes through one of the channels 9, where the electrode plate 62 electrostatically adsorbs the tar particles in the flue gas. At the same time, the condenser pipe 63 lowers the temperature of the oil fume, causing the tar to condense into liquid and flow into the channel 64. Finally, it enters the collection box 65 for collection. When the electrode plate 62 needs to be cleaned, the solenoid valve on the water distribution pipe 8 is opened, and the circulation pump 52 sends the washing liquid into the spray pipe 66 through the water distribution pipe 8. The two spray pipes 66 respectively flush and clean the two electrode plates 62 to remove the tar adhering to the surface of the electrode plates 62.

[0027] Further as Figure 3 As shown, it is worth noting that the odor removal device 7 includes a filter layer 71, a photocatalytic oxidation layer 72, an ultraviolet lamp 73, and a plasma purification layer 74. The filter layer 71, the photocatalytic oxidation layer 72, and the plasma purification layer 74 are all installed on the right side inside the treatment box 1 and are evenly distributed. The ultraviolet lamp 73 is installed on the top surface inside the treatment box 1 and faces the photocatalytic oxidation layer 72.

[0028] Specifically, the tar-removed smoke passes through another channel 9, where the odor is decomposed by the filter layer 71. At the same time, the ultraviolet lamp 73 irradiates the photocatalyst on the photocatalytic oxidation layer 72, generating free radicals to oxidize and decompose the odor substances. The plasma purification layer 74 performs deep treatment on the residual odor substances, improving the odor removal and deodorization effect of the smoke.

[0029] Further as Figure 3 and Figure 4 As shown, it is worth noting that the connecting pipe 55 is fixedly connected to the two nozzles 66 by the same water distribution pipe 8, and the two partitions 4 are both provided with channels 9 through their sides.

[0030] Specifically, the connecting pipe 55 is connected to the two spray pipes 66 through the water distribution pipe 8, so as to spray the washing liquid onto the surface of the electrode plate 62 for cleaning. The channel 9 allows the flue gas to pass through the treatment box 1 in an orderly manner.

[0031] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the input end of the circulating pump 52 is connected to the sedimentation tank 51, and solenoid valves are installed on both the connecting pipe 55 and the water distribution pipe 8.

[0032] Specifically, the input end of the circulating pump 52 is connected to the sedimentation tank 51 to pump out the washing liquid in the sedimentation tank 51. Solenoid valves are installed on the connecting pipe 55 and the water distribution pipe 8 to facilitate the cleaning of the electrode plate 62 by the staff.

[0033] Further as Figure 3 As shown, it is worth noting that the collection box 65 is connected to the through groove 64, and the output ends of the two nozzles 66 correspond one-to-one with the two electrode plates 62.

[0034] Specifically, the collection box 65 is connected to the through groove 64 to facilitate the collection of tar removed from the flue gas. The output ends of the two nozzles 66 correspond one-to-one with the two electrode plates 62 to ensure that the nozzles 66 can spray the washing liquid onto the electrode plates 62.

[0035] In summary: When using this equipment, the inlet pipe 2 is connected to the external fume generating equipment, and the exhaust pipe 3 is connected to the external emission equipment. The fumes enter the treatment box 1 through the inlet pipe 2. At this time, the circulation pump 52 is turned on, and the solenoid valve on the connecting pipe 55 is opened. The circulation pump 52 sends the washing liquid in the sedimentation tank 51 into the spray pipe 54 through the connecting pipe 55. The spray pipe 54 sprays the fumes, removing some particulate matter and soluble odor substances from the fumes. Then, the fumes pass through one of the channels 9. When electrode plate 62 is in operation, it electrostatically adsorbs tar particles. At the same time, condenser pipe 63 lowers the temperature of the oil fume, causing the tar to condense into liquid and flow into channel 64. Finally, it enters collection box 65 for collection. After long-term use, the solenoid valve on water distribution pipe 8 is opened, and circulation pump 52 sends washing liquid into spray pipe 66 through water distribution pipe 8. The two spray pipes 66 respectively flush and clean the two electrode plates 62, removing the tar adhering to the surface of the electrode plates 62, effectively avoiding the problem of poor tar removal effect of oil fume treatment equipment.

[0036] The tar-removed flue gas passes through another channel 9, where the filter layer 71 decomposes the odor. At the same time, the ultraviolet lamp 73 irradiates the photocatalyst on the photocatalytic oxidation layer 72, generating free radicals to oxidize and decompose the odor substances. The plasma purification layer 74 performs deep treatment on the residual odor substances. The treated and qualified gas is discharged through the exhaust pipe 3, effectively avoiding the problem of the single odor treatment method of the fume treatment equipment.

[0037] The circulating pump 52, electrode plate 62 and ultraviolet lamp 73 can be purchased from the market and are mature technologies in this field, which have been fully disclosed. Therefore, they will not be described again in the specification.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
