Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology in rubber production, specifically a novel treatment device for waste gas purification in rubber production. Background Technology

[0002] During rubber production, various additives are typically added and mixed to meet different processing requirements. This mixing process generates particulate matter, ammonia, and VOCs (volatile organic compounds). To prevent environmental pollution from these waste gases, waste gas purification equipment is used to suppress dust through spraying. Activated carbon is then used to adsorb and filter out sulfur dioxide and hydrogen sulfide from the waste gas, ensuring it is treated to be harmless before being released.

[0003] The existing utility model with authorization announcement number CN221618946U discloses a rubber production waste gas purification device, including a first filter box, a first air guide pipe, a second filter box, a gas detection box, and a second air guide pipe. The top of the first filter box is connected to a water supply pipe, the side of the first filter box is provided with a waste gas inlet, the inside of the first filter box is provided with a filter screen, and the first filter box is connected to the second filter box through the first air guide pipe.

[0004] The above technical solution allows for the drying of waste gas before adsorption using a water-absorbing component, thereby improving the adsorption and purification effect of activated carbon. The water-absorbing component is also easy to disassemble and replace the desiccant. However, the above technical solution has a low drying efficiency for waste gas after spray dust removal and cannot effectively remove organic matter from the waste gas, resulting in the inability to effectively render the organic matter harmless and affecting the purification effect of rubber production waste gas.

[0005] Therefore, those skilled in the art have provided a novel treatment device for purifying waste gas in rubber production to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a novel treatment device for purifying waste gas in rubber production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel treatment device for purifying waste gas in rubber production includes a base plate, a cooling cylinder arranged above the base plate, and a waste gas treatment mechanism arranged on the left side of the cooling cylinder.

[0009] The exhaust gas treatment mechanism includes an insulation cylinder located on the left side of the cooling cylinder. Four heating tubes are installed inside the insulation cylinder. An air intake pump is located on the left side of the insulation cylinder. The air inlet ends of the four heating tubes are fixedly connected to the air outlet end of the air intake pump. An induction coil is fitted onto the outer surface of each heating tube, and the energized end of each induction coil extends to the outside of the insulation cylinder. Four heat dissipation coils are installed inside the cooling cylinder. The air outlet end of each heating tube extends through the cooling cylinder and is fixedly connected to the air inlet end of the heat dissipation coil. The air outlet ends of the four heat dissipation coils extend through the cooling cylinder and are jointly connected to an exhaust pipe. A filter box is fixedly connected to the upper surface of the base plate. A microporous filter plate, a filter cotton plate, and an activated carbon filter plate are respectively snapped into the interior of the filter box. The exhaust end of the exhaust pipe extends through the filter box and reaches above the microporous filter plate.

[0010] As a further improvement of this utility model: a stabilizing base is fixedly connected to the bottom surface of the cooling cylinder, and the bottom surface of the stabilizing base is fixedly connected to the upper surface of the base plate.

[0011] As a further improvement of this utility model: a water inlet pipe is fixedly connected to the upper part of the outer surface of the cooling cylinder, and a water outlet pipe is fixedly connected to the left side of the cooling cylinder.

[0012] As a further improvement of this utility model: a support frame is fixedly connected to the outer surface of the heat preservation cylinder, and the bottom surface of the support frame is fixedly connected to the upper surface of the base plate.

[0013] As a further improvement of this utility model: a connecting flange is fixedly connected to the outer surface of the air inlet end of the air pump, and a plurality of connecting through holes are opened on the upper surface of the connecting flange.

[0014] As a further improvement of this utility model: the outer surfaces of the four heat dissipation coils are all fixedly connected to fixing plates, and the two sides of each fixing plate are fixedly connected to the inner wall of the cooling cylinder.

[0015] As a further embodiment of this utility model: the right side of the microporous filter plate, the right side of the filter cotton plate, and the right side of the activated carbon filter plate are all fixedly connected to a sealing plate. The left side of the sealing plate is in contact with the right side of the filter box. An exhaust pipe is fixedly connected to the right side of the filter box, and the exhaust pipe is located below the activated carbon filter plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention incorporates a waste gas treatment mechanism that rapidly increases the temperature of the heating element via an induction coil. Waste gas from the rubber production process is then drawn into the heating element by an air pump. The high temperature generated by the heating element itself rapidly carbonizes the organic particles in the waste gas and evaporates the moisture. The air is then cooled by a cooling coil and coolant inside a cooling cylinder before exiting through the outlet pipe into a filter box for filtration. Because the organic particles in the waste gas are heated to carbonization, they are better filtered and adsorbed by the filter cotton plate and activated carbon filter plate. This allows the rubber production waste gas treatment device to more efficiently dry the waste gas after spray dust removal and rapidly render the organic matter in the waste gas harmless through carbonization, ensuring the purification effect of the rubber production waste gas.

[0023] Please see Figure 1-4 A novel treatment device for purifying waste gas in rubber production includes a base plate 1, a cooling cylinder 2 is arranged above the base plate 1, a waste gas treatment mechanism 3 is arranged on the left side of the cooling cylinder 2, and a stabilizing seat 4 is fixedly connected to the bottom surface of the cooling cylinder 2. The bottom surface of the stabilizing seat 4 is fixedly connected to the upper surface of the base plate 1. The stabilizing seat 4 can fix the position of the cooling cylinder 2 on the base plate 1 and increase the stability of the cooling cylinder 2 during use.

[0024] The exhaust gas treatment mechanism 3 includes an insulation cylinder 301, which is located on the left side of the cooling cylinder 2. The insulation cylinder 301 has four heating tubes 302 inside. An air intake pump 303 is located on the left side of the insulation cylinder 301. A water inlet pipe 5 is fixedly connected to the upper part of the outer surface of the cooling cylinder 2, and a water outlet pipe 6 is fixedly connected to the left side of the cooling cylinder 2. The water inlet pipe 5 and the water outlet pipe 6 can be connected to the input and output pipes of the refrigeration unit. The coolant after cooling by the refrigeration unit is sent into the cooling cylinder 2 through the water inlet pipe 5. The coolant with a certain amount of heat after heat exchange inside the cooling cylinder 2 flows back into the refrigeration unit through the water outlet pipe 6, ensuring that the coolant inside the cooling cylinder 2 can always maintain a relatively low temperature.

[0025] The air inlet of each of the four heating tubes 302 is fixedly connected to the air outlet of the suction pump 303. An induction coil 304 is fitted on the outer surface of each heating tube 302. The power terminal of each induction coil 304 extends through to the outside of the insulation cylinder 301. A support frame 7 is fixedly connected to the outer surface of the insulation cylinder 301. The bottom surface of the support frame 7 is fixedly connected to the upper surface of the base plate 1. The support frame 7 can support the insulation cylinder 301, keep the insulation cylinder 301 at a suitable height, and ensure the normal use of the insulation cylinder 301.

[0026] The cooling cylinder 2 is equipped with four heat dissipation coils 305. The air outlet of each heating tube 302 passes through the cooling cylinder 2 and is fixedly connected to the air inlet of the heat dissipation coil 305. The outer surface of the air inlet of the suction pump 303 is fixedly connected with a connecting flange 8. Several connecting through holes 9 are opened on the upper surface of the connecting flange 8. The connecting flange 8 and the connecting through holes 9 can connect the air inlet of the suction pump 303 to the exhaust gas discharge pipe after the rubber production exhaust gas purification spray dust reduction, so that the exhaust gas to be treated can smoothly enter the interior of the heating tube 302.

[0027] The air outlets of the four heat dissipation coils 305 all pass through the cooling cylinder 2 and are connected to the air outlet pipe 306. A filter box 307 is fixedly connected to the upper surface of the base plate 1. Fixing plates 10 are fixedly connected to the outer surfaces of the four heat dissipation coils 305. Both sides of each fixing plate 10 are fixedly connected to the inner wall of the cooling cylinder 2. The fixing plates 10 can fix the position of the heat dissipation coils 305 inside the cooling cylinder 2, making it less likely for the heat dissipation coils 305 to loosen during use, thus increasing the reliability of the heat dissipation coils 305.

[0028] The filter box 307 contains a microporous filter plate 308, a filter cotton plate 309, and an activated carbon filter plate 310. The outlet end of the exhaust pipe 306 passes through the filter box 307 and extends above the microporous filter plate 308. The right side of the microporous filter plate 308, the right side of the filter cotton plate 309, and the right side of the activated carbon filter plate 310 are all fixedly connected to a sealing plate 11. The left side of the sealing plate 11 is in contact with the right side of the filter box 307. The right side of the filter box 307 is fixedly connected to an exhaust pipe 12, which is located below the activated carbon filter plate 310. The sealing plate 11 can seal the gaps between the microporous filter plate 308, the filter cotton plate 309, the activated carbon filter plate 310, and the filter box 307 to prevent unfiltered gas from leaking through the gaps. The exhaust pipe 12 allows the filtered gas inside the filter box 307 to be smoothly discharged to the outside.

[0029] The working principle of this utility model is as follows: In use, firstly, connect the suction pump 303 and the induction coil 304 to an external power supply and controller. Then, through the connecting flange 8 and the connecting through hole 9, connect the air inlet of the suction pump 303 to the exhaust pipe of the rubber production waste gas purification spray dust suppression system, allowing the waste gas to be treated to smoothly enter the heating tube 302. Next, connect the water inlet pipe 5 and the water outlet pipe 6 to the input and output pipes of the cooler. The coolant cooled by the cooler is sent into the cooling cylinder 2 through the water inlet pipe 5. The coolant inside the cooling cylinder 2, having undergone heat exchange and carrying a certain amount of heat, flows back into the cooler through the water outlet pipe 6, ensuring that the coolant inside the cooling cylinder 2 remains at a relatively low temperature. When the rubber production waste gas after dust suppression is sent into the heating tube 302 through the suction pump 303, when an alternating current of a certain frequency passes through the induction coil 304, an alternating magnetic field with the same frequency as the current change will be generated inside and outside it. At this time, the metal heating tube 302, under the action of the magnetic field, will generate… The induced current, with the same frequency but opposite direction to that of the induction coil 304, forms a closed loop along the surface of the heating tube 302, commonly referred to as an eddy current. This eddy current converts electrical energy into heat energy, rapidly heating the surface of the heating tube 302 to a high temperature. When the exhaust gas passes through the heating tube 302, the high temperature generated by the heating tube 302 rapidly carbonizes the organic particles in the exhaust gas and evaporates the moisture in the exhaust gas. Then, the air is cooled by the cooling coil 305 in conjunction with the coolant inside the cooling cylinder 2 before it can exit the exhaust. Pipe 306 enters the filter box 307 and is filtered by the microporous filter plate 308, filter cotton plate 309 and activated carbon filter plate 310. Finally, it is discharged to the outside through the exhaust pipe 12. Since the organic particles in the waste gas are heated to carbonization, they can be better filtered and adsorbed by the filter cotton plate 309 and activated carbon filter plate 310. This allows the rubber production waste gas treatment device to dry the waste gas after spray dust removal more efficiently and to quickly render the organic matter in the waste gas harmless through carbonization, thus ensuring the purification effect of the rubber production waste gas.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
