Abstract
Description
Technical Field
[0001] The invention relates to the technical field of tail gas treatment, and in particular to an energy-saving chemical machinery tail gas treatment device. Background Art
[0002] At present, the existing technology of chemical machinery exhaust gas treatment equipment mainly relies on the spraying method of exhaust gas treatment liquid. In this technology, the treatment liquid is evenly sprayed into the exhaust gas emission flow through a specific spraying device, aiming to capture and remove harmful components in the exhaust gas through chemical reactions or physical adsorption. However, this spraying method has certain limitations in terms of treatment efficiency, uniformity of treatment liquid distribution, and energy consumption, prompting the industry to continuously explore new exhaust gas treatment technologies that are more efficient and energy-saving.
[0003] After searching, it was found that the Chinese utility model patent with authorization announcement number CN216260014U discloses an energy-saving chemical machinery exhaust gas treatment device. This patent achieves sufficient spraying of exhaust gas treatment liquid and effective reaction of exhaust gas through the coordination of liquid storage tank, water pump, nozzle and dust removal device, and activated carbon plate, thereby improving the efficiency and effect of exhaust gas treatment, and the device has mobility; however, this patent directly sprays the exhaust gas flow through a nozzle or other spraying device. Although this method can reduce pollutants in the exhaust gas to a certain extent, its effect is limited by the mixing efficiency between the treatment liquid and the exhaust gas. The spraying method often leads to uneven distribution of the treatment liquid in the exhaust gas, and some exhaust gas may not be fully in contact with the treatment liquid, thereby affecting the removal effect of pollutants.

[0050] By adopting the above technical solution, the present invention has the following beneficial effects:
[0051] 1. Through the setting of the spiral conveying pipe and the built-in spiral sleeve, the exhaust gas passing through increases the movement distance in a limited area, increases the contact area and time with the filter, and further improves the filtering effect of the exhaust gas pretreatment link.
[0052] 2. Through the setting of wind power blades and filter screen 2, the pre-treated exhaust gas is dispersed by the wind power blades when entering the filter chamber for the next step of treatment, and then further physically filtered through filter screen 2 after dispersion. The dispersed exhaust gas has a better effect when it is subsequently filtered through adsorption materials.
[0053] 3. Through the arrangement of multiple filter cartridges and arc plates, the arc plates gather the dispersed exhaust gas at the corresponding filter cartridges respectively. Adsorption materials are arranged inside the filter cartridges to make the exhaust gas better contact with the adsorption materials in the filter cartridges, thereby further improving the quality of exhaust gas treatment.
[0054] 4. Through the setting of the mobile component and the heating chamber, the mobile component moves the inner sleeve of the filter cartridge that directly stores the adsorption material after long-term use to the inside of the heating chamber, and the adsorption material activated carbon is regenerated by heating by the heating device inside the heating chamber. The impurities previously adsorbed on its surface will flow out with the air as the temperature rises.
[0055] 5. Through the arrangement of the driving device and the outer shell and movable sleeve in the filter cartridge, when the inner sleeve is moved into the heating chamber, the driving device drives the movable sleeve to rotate, and after rotation, the mesh plate part of the outer shell is closed, so that the exhaust gas cannot pass through the filter cartridge where no adsorption material is stored, thereby avoiding the outflow of part of the exhaust gas without being filtered due to the regeneration of the adsorption material.
[0056] 6. By inserting the air outlet pipe into the water outlet pipe, the exhaust gas is directly discharged into the exhaust treatment liquid circulating in the water outlet pipe through the air outlet pipe, and finally enters the gas-liquid separation chamber through the water pump. The rotating parts of the water pump will further mix the gas and liquid, thereby improving the filtering effect.
[0057] 7. Through the setting of the air outlet hole and the injection sleeve on the air outlet pipe, the injection sleeve can quickly flush the dispersed exhaust gas into the circulating exhaust gas treatment liquid through the air outlet hole after pressurization. The air outlet hole is set as a small hole, so the exhaust gas flowing out is smaller, and finally less bubbles are generated after mixing with the exhaust gas treatment liquid.
[0058] 8. Through the setting of the baffle and the conical separation plate 1, the baffle is set at the center of the gas-liquid separation chamber, and the baffle blocks the gas-liquid mixture in the outlet pipe. After the gas-liquid mixture hits the baffle, part of the gas rises directly, while the liquid hits the top of the conical separation plate 1 downward to further quickly separate the gas and liquid.

[0091] The water outlet pipe 32 is suitable for discharging the gas-liquid mixture into the interior of the gas-liquid separation chamber 4 through a water pump.
[0092] like Figure 13-14 As shown, a bubble dispersion component 8 is disposed inside the air outlet pipe 31;
[0093] The bubble dispersion assembly 8 includes an injection sleeve 81, the interior of the injection sleeve 81 includes a concentration chamber 82 and an injection chamber 83, and the concentration chamber 82 communicates with the injection chamber 83;
[0094] The exhaust gas in the exhaust pipe 31 first passes through the concentration chamber 82 and then passes through the injection chamber 83 .
[0095] like Figure 4-5 As shown, a delivery pipe 11 is disposed inside the pretreatment cylinder 1, and the outlet of the delivery pipe 11 is communicated with the inner cavity of the filter chamber 2;
[0096] The delivery pipe 11 is arranged in a spiral shape;
[0097] A pre-treatment component is disposed inside the delivery pipe 11, and the pre-treatment component includes a spiral sleeve 12;
[0098] The spiral sleeve 12 is distributed in a spiral shape along the outer shape of the delivery pipe 11 . The spiral sleeve 12 divides the inner cavity of the delivery pipe 11 into a plurality of annular cavities. Corresponding air inlet grooves 13 are provided inside the plurality of annular cavities. A filter screen 14 is provided inside the air inlet groove 13 .
[0099] like Figure 6 As shown, the filter chamber 2 is provided with an air flow dispersion component, which includes a wind power blade 21 and a filter screen 22;
[0100] A circular groove 23 is provided inside the filter chamber 2, and the wind power blade 21 is rotatably installed in the circular groove 23, and the filter screen 22 is arranged on the top of the circular groove 23;
[0101] The outlet of the delivery pipe 11 is communicated with the circular groove 23 .
[0102] like Figure 7 As shown, at least one fixing plate 24 is connected to the interior of the filter chamber 2, and at least two filter cartridges 5 are arranged on the fixing plate 24;
[0103] Activated carbon is arranged inside the filter cartridge 5 , and the filter cartridge 5 is suitable for allowing the exhaust gas in the filter chamber 2 to pass through the filter cartridge 5 from bottom to top.
[0104] The working principle of this embodiment is as follows:
[0105] When in use, the tail gas outlet of the chemical machinery is connected to the inlet of the delivery pipe 11 through a pipe or other connecting pieces, and the tail gas is directly discharged into the interior of the delivery pipe 11 for pretreatment;
[0106] The delivery pipe 11 is spiral, which increases the travel of the exhaust gas in the delivery pipe 11 within a limited space, ensuring that the exhaust gas can have more contact with the filter screen 14 in the delivery pipe 11;
[0107] A spiral sleeve 12 is arranged inside the delivery pipe 11, and the spiral sleeve 12 is distributed in the entire spiral delivery pipe 11, so that the inner cavity of the delivery pipe 11 presents a spiral inner cavity, and the exhaust gas will rotate and flow inside the delivery pipe 11 when passing through. An annular air inlet groove 13 is provided in the part where the spiral inner cavity contacts the exhaust gas to accommodate impurities in the exhaust gas, and the exhaust gas contacts the filter screen 14 in the annular air inlet groove 13 when the spiral passes through, thereby achieving filtration;
[0108] This part increases the travel of the exhaust gas through the spiral conveying pipe 11, and then through the spiral sleeve 12, each exhaust gas can fully contact the filter screen 14, thereby improving the pretreatment effect;
[0109] The pre-treated exhaust gas flows into the circular groove 23 of the filter chamber 2 through the outlet of the delivery pipe 11. The force generated by the exhaust gas flow in the circular groove 23 drives the wind power blade 21 to rotate. The wind power blade 21 breaks up the exhaust gas entering the circular groove 23. The broken exhaust gas rises upward due to its own temperature and passes through the second filter screen 22. The second filter screen 22 further physically filters the exhaust gas.
[0110] After passing through the filter screen 22, the exhaust gas continues to rise and passes through a number of separately arranged filter cartridges 5, in which activated carbon, an adsorption material, is arranged. The cylindrical shape allows the exhaust gas to pass through the activated carbon more concentratedly and increases the contact area with the activated carbon, thereby improving the filtering effect.
[0111] Embodiment 2
[0112] like Figure 8-11 As shown, this embodiment further includes the following structure based on the first embodiment: the filter cartridge 5 includes an outer shell 51, a movable sleeve 53 and an inner sleeve 55;
[0113] The outer circumference of the shell 51 is fixedly connected to the fixing plate 24, and the two ends of the shell 51 are fixedly connected to the inner wall of the filter chamber 2. The shell 51 is hollow, and a gas passage groove is provided on the shell 51 to penetrate the shell 51, and a mesh plate 52 is installed in the gas passage groove.
[0114] The movable sleeve 53 is rotatably mounted inside the housing 51. The outer peripheral surface of the movable sleeve 53 is tightly fitted with the inner wall of the housing 51. The movable sleeve 53 is hollow and has an opening 54 that penetrates the movable sleeve 53.

[0116] The inner sleeve 55 is movably disposed inside the movable sleeve 53 . The inner sleeve 55 is hollow and has a plurality of pores 56 . The activated carbon is disposed inside the inner sleeve 55 .
[0117] like Fig.12 As shown, the exhaust gas treatment device further includes a heating chamber 7, a moving assembly 6 is disposed inside the heating chamber 7, and a driving device 61 is disposed outside the heating chamber 7;
[0118] The moving assembly 6 is adapted to be driven by the driving device 61 to drive the inner sleeve 55 to move to the inside of the heating chamber 7, and a heating assembly is arranged outside the heating chamber 7;
[0119] The heating assembly comprises a heating device 71 and a heating tube 72, wherein the heating tube 72 is adapted to connect the heating device 71 and the heating chamber 7;
[0120] The heating device 71 is adapted to transfer heat to the interior of the heating chamber 7 through the heating tube 72;
[0121] A gas purifier 73 is installed on one side of the heating chamber 7 .
[0122] like Fig.12 As shown, the moving assembly 6 includes a threaded rod 62 and a transmission sleeve 63;
[0123] The threaded rod 62 is rotatably mounted inside the heating chamber 7, and the transmission sleeve 63 is assembled outside the threaded rod 62. The threaded rod 62 is suitable for being driven to rotate by the driving device 61 to drive the transmission sleeve 63 to move linearly along the axis of the thread.
[0124] The transmission sleeve 63 is connected to the inner sleeve 55, and the transmission sleeve 63 is suitable for driving the inner sleeve 55 to move linearly;
[0125] The rotating assembly includes a driving bevel gear 68, a driven bevel gear 69 and a connecting plate 66;
[0126] The driven bevel gear 69 is fixedly sleeved on the outer peripheral surface of the movable sleeve 53, the connecting plate 66 is connected to the inside of the heating chamber 7, a rotating shaft is rotatably installed inside the connecting plate 66, the driving bevel gear 68 is connected to one end of the rotating shaft, and the driven bevel gear 69 is meshed and connected with the driving bevel gear 68;
[0127] The other end of the rotating shaft is connected to a rotating gear 67, and the transmission sleeve 63 is connected to a rack 65;
[0128] The rack 65 is adapted to move with the transmission sleeve 63 and mesh with the rotating gear 67 to drive the active bevel gear 68 to rotate, thereby driving the driven bevel gear 69 and the movable sleeve 53 to rotate;
[0129] The top of the transmission sleeve 63 is connected with a limiting plate 64 , and a limiting groove corresponding to the limiting plate 64 is formed on the top wall of the heating chamber 7 , and the limiting plate 64 is slidably connected inside the limiting groove.
[0130] like Figure 2 As shown, a plurality of arc-shaped plates 25 are connected to the bottom of the fixed plate 24, and a diameter-dividing channel is formed between every two arc-shaped plates 25, and the diameter-dividing channel corresponds to the position of the filter cartridge 5;
[0131] Each of the arc-shaped plates 25 is provided with a through hole 26 penetrating through the arc-shaped plates 25 .
[0132] The working principle of this embodiment is as follows:
[0133] The filter cartridge 5 is divided into three layers, namely, an outer shell 51, a movable sleeve 53 and an inner sleeve 55. The outer shell 51 is connected to the fixed plate 24, and the outer shell 51 is fixedly arranged. The outer peripheral surface of the movable sleeve 53 is rotatably mounted on the inner wall of the outer shell 51. The inner sleeve 55 is used to place the adsorption material, and the inner sleeve 55 is movably nested inside the movable sleeve 53.
[0134] The upper and lower parts of the outer shell 51 are provided with mesh plates 52 for the exhaust gas to pass through. The inner sleeve 55 is divided into an opening part and a solid part. When the exhaust gas is allowed to pass through, the opening part corresponds to the position of the mesh plate 52. When the exhaust gas is not allowed to pass through, the solid part is rotated to correspond to the mesh plate 52, so as to achieve the effect of closing the outer shell 51. The inner sleeve 55 is provided with a plurality of fine holes 56. The fine holes 56 allow the exhaust gas to pass through while ensuring that the adsorbent material stored therein will not leak out.
[0135] The surface of the adsorption material activated carbon will adsorb a large amount of impurities brought by the exhaust gas after long-term use, thereby reducing the adsorption effect of the activated carbon. Therefore, after long-term practical use, the activated carbon inside the inner sleeve 55 needs to be replaced or regenerated. The movable inner sleeve 55 can be driven by the moving component 6 and moved to the inside of the heating chamber 7 for regeneration. In order to avoid the equipment not being able to work normally during the regeneration of the activated carbon, the corresponding inner sleeves 55 in the multiple filter cartridges 5 can be controlled separately, and there is no need to regenerate them at the same time. It can be selected according to the actual situation.
[0136] When the inner sleeve 55 corresponding to the activated carbon to be regenerated is moved to the inside of the heating chamber 7, the driving device 61 corresponding to the inner sleeve 55 is started, and the driving device 61 drives the corresponding threaded rod 62 to rotate. When the threaded rod 62 rotates, it drives the corresponding transmission sleeve 63 to make a linear motion along the axial direction of the thread. The transmission sleeve 63 is fixedly connected to one end of the inner sleeve 55, so that the inner sleeve 55 can be driven to move together while moving, until the inner sleeve 55 is moved to the inside of the heating chamber 7. The function of the limit plate 64 is to further prevent the transmission sleeve 63 from being driven by the threaded rod 62 to rotate, thereby improving the stability of the movement of the transmission sleeve 63;
[0137] It should be noted that when the inner sleeve 55 is moved to the heating chamber 7, the corresponding outer shell 51 will be closed to prevent the exhaust gas from passing through the outer shell 51 without activated carbon. The closing of the outer shell 51 is synchronized with the movement of the inner sleeve 55. When the inner sleeve 55 is driven to move by the transmission sleeve 63, the rack 65 on one side of the transmission sleeve 63 meshes with the rotating gear 67 to reverse the rotating gear 67. When the rotating gear 67 reverses, it drives the active bevel gear 68 to rotate. Through the meshing of the active bevel gear 68 and the driven bevel gear 69, the movable sleeve 53 is rotated until the solid part of the movable sleeve 53 covers the mesh plate 52 of the outer shell 51. At this time, the outer shell 51 is closed. On the contrary, when the activated carbon in the inner sleeve 55 is regenerated, the inner sleeve 55 is reset to the inside of the movable sleeve 53. The movable sleeve 53 is also reset by rotation to align its opening 54 with the mesh plate 52. At this time, the outer shell 51 is opened, and the exhaust gas can pass normally to filter the exhaust gas.
[0138] When the inner sleeve 55 is moved to the interior of the heating chamber 7, the heating device 71 is started, and the heat is transferred to the interior of the heating chamber 7 through the heating tube 72. The activated carbon is regenerated under the action of high temperature. The high temperature causes the organic impurities attached to the surface of the activated carbon to volatilize into gas, which is discharged with the hot air flow, thereby playing a regeneration role. The discharged gas flows out of the interior of the heating chamber 7 through the gas purifier 73 and is filtered to prevent the gas from causing harm to the environment and human body.
[0139] It should be noted that, in order to avoid the influence of high temperature on the inner sleeve 55, the inner sleeve 55 should be made of high temperature resistant material.
[0140] In order to improve the efficiency of exhaust gas filtration, a plurality of arc-shaped plates 25 corresponding to each filter cartridge 5 are arranged at the bottom of the fixed plate 24. The arc-shaped plates 25 can gather the rising exhaust gas in the filter chamber 2 and guide it to the corresponding filter cartridge 5, so as to assist the exhaust gas to pass through the filter cartridge 5, thereby improving the filtration effect, avoiding the continuous replacement of activated carbon by regeneration, achieving energy saving effect, and the heat generated can be collected and reused;
[0141] A through hole 26 is provided on each arc plate 25, and the through hole 26 is provided to prevent the outer shell 51 of part of the filter cartridge 5 from being partially closed. When the activated carbon in the inner sleeve 55 is being regenerated, the exhaust gas cannot pass normally, thereby causing accumulation. The exhaust gas that cannot pass through will be allowed to pass through along the inflow of the through hole 26, and can be filtered normally at the filter cartridge 5.
[0142] Embodiment 3
[0143] like Fig.14As shown, this embodiment further includes the following structure on the basis of the first embodiment: a separation assembly is arranged inside the gas-liquid separation chamber 4, and the separation assembly includes a baffle 41, a conical separation plate 1 42, a filter screen 3 43 and a conical separation plate 2 44;
[0144] The baffle 41 is connected to the inner wall of the gas-liquid separation chamber 4. The baffle 41 is suitable for colliding with the gas-liquid mixture flowing out of the water outlet pipe 32. The position where the baffle 41 contacts the gas-liquid mixture is located at the axis of the gas-liquid separation chamber 4.
[0145] The conical separation plate 1 42 and the conical separation plate 2 44 are both provided with a plurality of holes penetrating therethrough;
[0146] The conical separation plate 1 42 is located directly below the baffle 41, and the conical separation plate 2 44 is located above the baffle 41;
[0147] The filter screen three 43 is located below the conical separation plate one 42;
[0148] A circulation pipe 9 is connected between the gas-liquid separation chamber 4 and the liquid storage tank 33 . The circulation pipe 9 is suitable for being connected through a water pump to pump out the liquid in the gas-liquid separation chamber 4 to the inside of the liquid storage tank 33 .
[0149] The working principle of this embodiment is as follows:
[0150] After the exhaust gas is processed by the pre-treatment cylinder 1 and the filter chamber 2, some impurities in the exhaust gas have been processed, and the exhaust gas treatment liquid is required to complete the final filtering work;
[0151] After the treatment in the filter chamber 2 is completed, the air pump needs to be started to draw the exhaust gas in the filter chamber 2 into the interior of the exhaust pipe 31. The outlet of the exhaust pipe 31 is obliquely inserted into the interior of the water outlet pipe 32. The water outlet pipe 32 continuously draws out the exhaust treatment liquid in the liquid storage tank 33 under the action of the water pump to form a flowing exhaust treatment liquid. After the exhaust gas is discharged through the exhaust pipe 31, it directly enters the interior of the flowing exhaust treatment liquid. Due to the fluidity of the liquid, the exhaust gas can be better mixed with the exhaust treatment liquid, thereby improving the filtering effect.
[0152] It should be noted that the outlet pipe 31 is obliquely inserted into the outlet pipe 32, and the joint between the two needs to be sealed. The oblique insertion of the outlet pipe 31 can prevent the flowing exhaust treatment liquid from causing a greater impact on the outlet pipe 31;
[0153] When the tail gas passes directly through the tail gas treatment liquid, bubbles will be generated. If the bubbles are too large, it will affect the full mixing of the two. Therefore, an injection sleeve 81 is arranged inside the outlet pipe 31. The injection sleeve 81 is divided into a concentration chamber 82 and an injection chamber 83. The concentration box can compress the tail gas, and the compressed tail gas diffuses outward in the injection chamber 83, so that the tail gas is dispersed and poured into the outlet hole 34 at a faster speed. After flowing into the outlet hole 34, it mixes with the tail gas treatment liquid. The outlet hole 34 adopts a small diameter. When the gas passes through the small diameter outlet hole 34, it will be dispersed into many small bubbles. The small bubbles have a larger surface area to volume ratio than large bubbles. This means that in the same volume of gas, the small bubbles provide more surface area to contact with the liquid. In this way, the contact area between the gas and the liquid is increased, which helps to improve the reaction efficiency and mass transfer rate.
[0154] It should be noted that in order to prevent the exhaust gas treatment liquid in the water outlet pipe 32 from flowing back into the outlet pipe 31 , the pressure in the outlet pipe 31 should be greater than that in the water outlet pipe 32 , and a check valve is provided inside the outlet pipe 31 .
[0155] When the gas-liquid mixture passes through the water pump, the rotating part of the water pump will further promote the mixing of the gas and the liquid, and finally the gas-liquid mixture will be passed into the interior of the gas-liquid separation chamber 4 through the water outlet pipe 32, and the gas-liquid mixture inside the gas-liquid separation chamber 4 will collide with the baffle 41 located at the center of the gas-liquid separation chamber 4, and the gas-liquid mixture after the collision will disperse, the gas will rise upward, and the liquid will hit the top position of the conical separation plate 42 downward, and the liquid will be dispersed again after hitting the top, further separating the gas inside it, and at the same time, the liquid will be dispersed more evenly after hitting the top, and will evenly pass through the conical separation plate 42 and flow to the filter net 3 43, and the filter net 3 43 can filter the liquid to a certain extent, and after filtering, it will flow back to the interior of the liquid storage tank 33 through the circulation pipe 9 for recycling;
[0156] After the gas-liquid mixture is hit twice by the baffle 41 and the conical separation plate 42, the separated gas will rise to the top of the gas-liquid separation chamber 4, but there is still a small amount of liquid in the gas. Therefore, the separated gas needs to pass through the conical separation plate 44 during the rising process to further separate the moisture inside it. Finally, the pure gas flows out through the outlet of the gas-liquid separation chamber 4.
[0157] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
