An exhaust gas treatment device for automobile window film processing

Abstract

The present invention discloses an exhaust gas treatment device for the automotive window film processing process, belonging to the technical field of exhaust gas treatment devices. The device comprises a high-temperature oxidation exhaust gas reactor. Exhaust gas enters through a first air intake box connected to the bottom of the reactor, and air enters through a second air intake box connected to the top of the reactor. A heat exchange box is provided on one side of the reactor. The reactor and the heat exchange box are connected by a first air supply pipe. Heat in the heat exchange box is transferred to the interior of the reactor through a heat exchange component. The reactor comprises a preheating chamber, a reaction chamber, a heat storage body, a first air storage chamber, a second air storage chamber, a second air supply pipe, and a hollow pipe. The present invention utilizes the heat generated by the high-temperature oxidation of VOC exhaust gas and oxygen to preheat the air entering the reactor. Simultaneously, the VOC exhaust gas is heated by the heat storage body, resulting in a higher initial temperature for both the air and the VOC exhaust gas upon contact, significantly shortening the time it takes to reach the high-temperature oxidation temperature.

Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device during the processing of automobile window films. Background Art

[0002] RTO, also known as regenerative thermal incinerator, is an environmentally friendly device that uses heat energy to directly burn waste gas. It can treat waste gas from almost all industries such as spray painting, baking paint, printing, plastics, chemicals, electrophoresis, coating, electronics, etc. 3 RTO has an effect on waste gas within a certain range that other purification technologies cannot achieve. In addition, high-concentration organic waste gas can be concentrated through adsorption and then passed into the RTO direct combustion device. The pickled packed bed (also known as the heat storage body) can maximize the recovery of heat energy. After heat monitoring, the recovery rate reached 95%. Therefore, when using RTO to treat industrial organic waste gas (VOCs), it can save a lot of fuel consumption and reduce waste gas purification costs.

[0003] However, in actual use, existing RTO combustion furnaces often use heat storage bodies, often ceramic heat storage bodies, to maintain high temperatures during the reaction process, and recycle the heat in the caloric water vapor and carbon dioxide generated by the exhaust gas and oxygen during the high-temperature oxidation process. However, in the actual production process, industrial organic waste gas (VOCs) is often generated during the baking process and has a certain temperature itself, while the air enters at room temperature, so both gases have a heating process before the reaction. For this reason, we propose an exhaust gas treatment device for the automobile window film processing process to realize the preheating process of the air and exhaust gas to solve the above problems.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Compared with the process of exhaust gas and air entering the reactor in the prior art, the overall design of the present invention utilizes the heat generated by the high-temperature oxidation of VOC exhaust gas and oxygen to preheat the air entering the reactor. At the same time, the VO exhaust gas is heated by the heat storage body, so that the initial contact temperature of the air and VOC exhaust gas is relatively high, and the time to reach the high-temperature oxidation temperature is greatly shortened, thereby improving the reaction efficiency and further improving the exhaust gas treatment efficiency. In addition, the heat generated can also be used for drying ovens or daily water heating, etc.

[0018] 2. By setting up the adjustment component, when the VOC exhaust gas enters the reactor through the first air inlet box, it will push the connecting shaft tube to rotate. Under the action of the threaded cooperation between the fixed cylinder and the threaded rod, the threaded rod will rise first. After rising until the thread is disengaged, the threaded rod and the fixed cylinder will only rotate relative to each other, and the threaded rod will no longer rise, so that the air inlet is exposed and maintained, which facilitates the air to enter the preheating chamber.

[0019] 3. By setting up an opening and closing component, when the height of the conical platform rises, the cover plate is driven to move to the side of the air inlet, thereby exposing the air inlet and allowing air to enter the reactor to participate in the reaction. When the reaction is over, the sliding rod is reset under the action of the reset component to block the air inlet and maintain the sealing state of the preheating chamber, so that the entry of air is synchronized with the reaction process. When the reaction starts, air enters, and when the reaction stops, the air input stops.

[0020] 4. By setting a reset component and cooperating with the adjustment component, during the reaction process, the heat transfer oil expands due to heat and partially enters the oil storage sleeve. At this time, the heat transfer oil has not yet filled the oil storage sleeve. The hydraulic oil inside the oil storage sleeve acts as a damping fluid, and cooperates with the conical platform to make the speed of the counterweight block rising inside the oil storage sleeve relatively constant; after the heat transfer oil temperature rises to a certain temperature, it remains constant. At this time, the heat transfer oil expands to fill the oil storage sleeve. At this time, the pressure inside the oil storage sleeve is constant, and cooperates with the connecting line body to make the height of the counterweight block constant; when the reaction process stops, the overall temperature drops, causing the heat transfer oil temperature to drop. Compared with the state when the heat transfer oil is filled, the inside of the oil storage sleeve is in a negative pressure state, thereby causing the counterweight block to drop in height, and then pulling the guide block to move to the initial position; in summary, the cover plate can expose the air inlet during the reaction process. After the reaction process is over, the cover plate will block the air inlet. At the same time, the heat transfer oil can act as a damping fluid, making the moving speed of the counterweight block relatively constant. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] This embodiment provides an exhaust gas treatment device for automobile window film processing. Figure 1-11, including installing a high-temperature oxidation exhaust gas reactor 1 at a designated location in the factory. The industrial organic waste gas (VOCs), hereinafter referred to as VOC, generated during the processing of automobile window film enters the interior through a first air intake box 2 connected to the bottom of the reactor 1, and air enters from a second air intake box 3 connected to the top of the reactor 1, and a sealed box cover is hinged on the top of the second air intake box 3. The air enters the reactor 1 through the second air intake box 3 and reacts with the VOC exhaust gas entering the reactor 1 through the first air intake box 2. At the same time, a heat exchange box 4 is provided on one side of the reactor 1, and a heat exchange component 5 is installed inside the heat exchange box 4. The reactor 1 and the heat exchange box 4 are connected by a first air supply pipe 6, and a connecting rod is also provided under the first air supply pipe 6 to strengthen the connection between O1 and O4. The VOC exhaust gas is oxidized into water and carbon dioxide at high temperature with oxygen in the air in the reactor 1. The water vapor and carbon dioxide carry a large amount of heat and are transferred to the heat exchange box 4 and discharged through the smoke outlet at the top.

[0040] Reference Figure 4 The heat exchange assembly 5 in this embodiment is specifically described. The heat exchange assembly 5 includes a cold oil pipeline 501, a hot oil pipeline 502, a heat dissipation pipe 503 and a heat exchange pipe 504 that are interconnected. The heat exchange pipe 504 is spirally wound in multiple groups inside the heat exchange assembly 5, and heat exchange oil is set inside. The heat dissipation pipe 503 is set in a circular shape inside the preheating chamber 101. The top and bottom ends of the heat exchange pipe 504 are connected to the two ends of the heat dissipation pipe 503 through the cold oil pipeline 501 and the hot oil pipeline 502 respectively. The heat exchange oil is in the heat exchange box 4. After being heated by the exhaust gas, the heat exchange oil flows through the hot oil pipe 502 at the bottom to the heat exchange pipe 503 to heat the air in the preheating chamber 101. In this embodiment, the heat exchange pipe 503 is arranged in a wave shape inside the preheating chamber 101, and a threaded pipe type arrangement can also be adopted. After the heat exchange oil heats the air inside the preheating chamber 101, its own temperature will also drop. After the temperature drops, the heat exchange oil flows through the cold oil pipe 501 to the heat exchange pipe 504 to continue to be heated by the exhaust gas, thus repeating the cycle and continuously heating the air inside the preheating chamber 101.

[0041] It is also worth mentioning that the initial ignition of combustion inside the reactor 1 relies on natural gas. When the heat of the exhaust gas is not enough to maintain the high temperature inside the reactor 1, natural gas will also be burned to maintain the temperature of the furnace body. The heat generated by the initial ignition of the reactor 1 is supplied to the oven in the production process of the automobile window film, so that the exhaust gas containing VOCs will evaporate into the interior of the reactor 1. At the same time, the heat generated can also be used for the oven or for daily use to boil water, etc.

[0042] Reference Figure 3The reactor 1 in this embodiment is described in detail. The interior of the reactor 1 is divided into a preheating chamber 101, a reaction chamber 102, a heat storage body 103, a first gas storage chamber 104, and a second gas storage chamber 105 from top to bottom. A plurality of second air supply pipes 106 are distributed in a circumferential array on the outside of the reactor 1 and connect the preheating chamber 101 and the reaction chamber 102. The preheating chamber 101 and the reaction chamber 102 are connected by the second air supply pipes 106. Air enters the preheating chamber 101 from the second air inlet box 3 and is preheated by the heat pipe 503. The heated air enters the reaction chamber 102 through the second air supply pipe 106. At the same time, the VOC exhaust gas enters the first air inlet box 2 from the air inlet pipe and further enters the second gas storage chamber 105, where it is heated by the heat storage body and then enters The exhaust gas enters the first gas storage chamber 104 and passes through the heat storage body 103. Many through holes are opened inside the heat storage body 103 to facilitate the passage of exhaust gas. Since the heat storage body 103 is made of heat storage ceramic, the exhaust gas can be further heated and heat is provided for the combustion of VOC exhaust gas and oxygen in the reaction chamber 102. After passing through the heat storage body 103, the VOC exhaust gas enters the reaction chamber 102 and reacts with the air transmitted from the second air supply pipe 106. The water vapor and carbon dioxide produced after the reaction enter the heat exchange box 4 through the first air supply pipe 6 and are discharged to the outside. In addition, an empty pipe, that is, a hollow pipe 107, is opened in the middle of the reactor 1. The bottom end of the hollow pipe 107 is connected to the first air inlet box 2, and passes through the entire reactor 1 from bottom to top, and the top is connected to the second air inlet box 3.

[0043] Reference Figure 2 and Figure 5-11 , the internal structure of the first air inlet box 2 in this embodiment is specifically described. The regulating component 7 is arranged in the hollow pipe 107 inside the reactor 1, the bottom end extends to the interior of the first air inlet box 2 and is rotatably connected to the inner bottom wall, and the top end extends to the interior of the second air inlet box 3. The interior of the second air inlet box 3 is provided with an opening and closing component 8 and a reset component 9, and the top end of the regulating component 7 is connected to the opening and closing component 8. The regulating component 7 and the opening and closing component 8 are adjusted by the reset component 9. The top wall of the reactor 1 is provided with a plurality of air inlets 13 for air to enter; please refer to Figure 6 In this embodiment, when the regulating assembly 7 rotates, the opening and closing assembly 8 exposes the blocked air inlet 13 , so that air can enter the preheating chamber 101 from the air inlet 13 .

[0044] Specific reference Figure 3, the first air intake box 2 of this embodiment is specifically described. The interior of the first air intake box 2 is separated by a partition plate 201. Multiple partition plates 201 can be used to divide the interior of the first air intake box 2 into multiple drive turbines 203, and the internal cavity of the first air intake box 2 is divided into two air storage chambers 202. In this embodiment, for the convenience of description, the number of partition plates 201 is set to one for description. In this embodiment, the partition plate 201 and the bottom wall of the reactor 1 are both provided with a plurality of air holes for the exhaust gas to pass through. The end of the regulating component 7 is located at A driving turbine 203 is installed at a position inside the air storage chamber 202. One side wall of the first air intake box 2 is connected to the air intake pipe for easy entry of exhaust gas. The air holes on the surface of the partition plate 201 are away from the air intake pipe, and the air holes on the bottom wall of the reactor 1 are away from the air holes opened on the partition plate 201. When the VOC exhaust gas generated during the processing of the automobile window film enters the first air intake box 2, the exhaust gas passes through the partition plate 201 and the air holes opened on the bottom wall of the reactor 1 in turn, forming a vortex to drive the driving turbine 203 to rotate, and further drive the adjustment component 7 to rotate.

[0045] Reference Figure 7-8 , the adjusting component 7 in this embodiment is described in detail. The connecting shaft tube 701 is hollow and is located inside the hollow pipe 107 and is rotatably connected to the hollow pipe 107, and heat transfer oil is filled inside the connecting shaft tube 701. The fixed cylinder 702 is fixedly arranged at the top of the connecting shaft tube 701 and is communicated with the internal cavity of the connecting shaft tube 701. The interior of the fixed cylinder 702 is provided with an internal thread, and a threaded rod 703 is sleeved inside the fixed cylinder 702. The two are lifted and lowered by threaded cooperation. When the turbine 203 is driven to rotate, the connecting shaft tube 701 is driven to rotate. Under the threaded cooperation, the threaded rod 703 moves upward in the fixed cylinder 702. After moving to a certain extent, the thread on the outer surface of the threaded rod 703 is disengaged from the thread inside the fixed cylinder 702, so that the height of the threaded rod 703 no longer rises.

[0046] Reference Figure 8, further explaining the adjustment assembly 7 in this embodiment, in this embodiment, the number of fixed ring plates 704 is set to two, and a circular ring rail 708 is opened on the outer side of the fixed ring plate 704. The two fixed ring plates 704 are symmetrically welded to the top side wall of the connecting shaft tube 701 and form a first oil channel with a trapezoidal vertical cross-section shape. The side wall of the connecting shaft tube 701 located next to the oil channel is provided with eight oil leakage holes 705 in a circumferential array. The outer surface of the connecting shaft tube 701 is provided with a fixed ring shell 706, and the interior of the fixed ring shell 706 is opened with a second oil channel. The upper and lower side walls of the fixed ring shell 706 are provided with holes at positions corresponding to the ring rail 708. The annular groove 707 and a sealing gasket are installed between the annular groove 707 and the annular rail 708 to form a sealed rotating connection. The fixed ring plate 704 will rotate along with the connecting shaft tube 701, and the fixed ring shell 706 will be fixed in place. The connecting shaft tube 701 is connected to the fixed ring plate 704 and the fixed ring shell 706 through the oil leakage hole 705. When the temperature of the heat storage ceramic inside the reactor 1 rises, the hollow pipe 107 will be heated, and then the internal connecting shaft tube 701 will be heated, so that the heat transfer oil inside the regulating assembly 7 will expand in volume after being heated, and then flow from the oil leakage hole 705 to the first oil channel and further to the second oil channel.

[0047] Reference Figure 9 , the opening and closing assembly 8 in this embodiment is specifically described. The conical platform 801 is set in the shape of a quadrangular pyramid. Each inclined surface corresponds to a first guide block 802, and the bottom end of the conical platform 801 is fixedly connected to the top of the threaded rod 703. Each first guide block 802 is inclined near a side wall of the conical platform 801 and cooperates with the conical platform 801. One end of the sliding rod 803 is fixedly connected to the first guide block 802, and the other end of the sliding rod 803 is connected to the cover plate 804 through a connecting frame 805. The cover plate 804 is located on one side of the air inlet 13 to block the air inlet 13. When the conical platform 801 rises, the first guide block 802 is squeezed to drive the sliding rod 803 to move to one side, thereby driving the cover plate 804 to move to the side of the air inlet 13, thereby exposing the air inlet 13, thereby facilitating air to enter the preheating chamber 101 through the air inlet 13. A sealing groove 14 is provided inside the air inlet 13, and a sealing gasket 15 is provided outside the cover plate 804. The sealing gasket 15 is embedded in the sealing groove 14 to achieve sealing.

[0048] In the initial state, the cover plate 804 is located above the air inlet 13 to block the air inlet 13, and the sealing gasket 15 is embedded in the sealing groove 14 to seal the edge of the cover plate 804. When the height of the conical platform 801 rises, the inclined surface of the conical platform 801 rises, thereby squeezing the first guide block 802, causing the first guide block 802 to move outward, thereby driving the cover plate 804 to move toward the side of the air inlet 13 through the sliding rod 803, thereby exposing the air inlet 13, and then allowing air to enter the preheating chamber 101 through the air inlet 13.

[0049] Continue to refer to Figure 9 , the way the opening and closing assembly 8 in this embodiment moves is supplemented by explanation. Two guide grooves 806 parallel to each other and to the inclined surface are opened on the inclined surface of the conical platform 801. Second guide blocks 807 are installed on both sides of the first guide block 802. The second guide blocks 807 are embedded in the guide grooves 806 and rotate. Therefore, when the conical platform 801 squeezes the first guide block 802, it is actually the second guide block 807 that rotates inside the guide grooves 806, which reduces mechanical friction, prolongs the service life of the structure and reduces jamming.

[0050] Reference Figure 11 , the movement mode of the sliding rod 803 in this embodiment is further explained. A limiting sleeve 10 is provided on the outside of each sliding rod 803. The limiting sleeve 10 is fixed to the inside of the first air intake box 2 through a fixing frame. A threaded guide groove 11 is spirally provided inside the limiting sleeve 10. A plurality of rotatable guide balls 12 are provided inside the threaded guide groove 11. One end of the sliding rod 803 passes through the inside of the limiting sleeve 10 and contacts with the guide ball 12. When the first guide block 802 drives the sliding rod 803 to move outward, the outer surface of the sliding rod 803 contacts with the 12 inside 10, and the mechanical friction is reduced by the rotation of 12. At the same time, 10 supports and limits the sliding rod 803.

[0051] Continue to refer to Figure 11 , the reset assembly 9 in this embodiment is described in detail. The number of oil storage sleeves 901 is equal to the number of sliding rods 803, which is also four and falls below the four sliding rods 803 respectively. The oil storage sleeve 901 and the fixed ring shell 706 at the top of the adjustment assembly 7 are connected through the oil guide pipe 902. The heat-conducting oil expanded by heat passes through the first oil channel and the second oil channel and enters the oil guide pipe 902, and further enters the interior of the oil storage sleeve 901. One end of the connecting wire body 903 is fixedly connected to the first guide block 802, and the other end of the connecting wire body 903 extends to the inside of the oil storage sleeve 901 to connect the counterweight block 904. The counterweight of the counterweight block 904 can be changed. The guide wheel 905 is located above the connecting wire body 903 and below the connecting wire body 903. The angle of the connecting wire body 903 is changed by the guide wheel 905.

[0052] When the first guide block 802 moves outward, it pulls the connecting wire body 903, causing the counterweight 904 connected to the tail end of the connecting wire body 903 to move upward. At this time, the heat-conducting oil in the connecting shaft tube 701 expands due to heat and enters the oil storage sleeve 901. At this time, the oil storage sleeve 901 has not been filled. The hydraulic oil in the oil storage sleeve 901 acts as a damping fluid, so that the speed of the counterweight 904 when rising inside the oil storage sleeve 901 is relatively constant, so that the speed of the opening and closing component 8 moving and the adjustment component 7 rotating remains in a relatively constant state. Since the reaction inside the reactor 1 is still continuing at this time, the heat-conducting oil maintains a high temperature until the heat-conducting oil fills the oil storage sleeve 901. At this time, the pressure inside the oil storage sleeve 901 is constant, so that the height of the counterweight 904 remains constant.

[0053] In addition, when the reaction inside the reactor 1 is completed and the entire equipment is closed, as time goes by, the temperature of the heat transfer oil inside the connecting shaft tube 701 gradually decreases, the volume of the heat transfer oil decreases, and the heat transfer oil inside the oil storage sleeve 901 gradually falls back to the inside of the connecting shaft tube 701. At this time, compared with the heated state, the inside of the oil storage sleeve 901 is in a negative pressure state, so that the counterweight block 904 gradually decreases, and the counterweight block 904 decreases and then pulls the first guide block 802 to move inward, so that the cover plate 804 moves to the initial position, gradually blocking the air inlet 13, thereby closing the air entry. If you need to stop the air entry quickly, you only need to close the box cover at the top of the second air inlet box 3 to stop the air entry.

[0054] Reference Figure 6 and Figure 9 In this embodiment, the conical platform 801 maintains a vertical rise when it rises. Corner blocks 16 are installed at the corners of the conical platform 801, and guide rods 17 equal in number to the corner blocks 16 are installed inside 02, so that the conical platform 801 is limited by the cooperation between the corner blocks 16 and the guide rods 17 when it rises.
