Technical Field

[0001] This application relates to the field of rubber exhaust gas technology, and in particular to an exhaust gas treatment device for the rubber industry. Background Technology

[0002] In the production of rubber products, a large amount of organic waste gas is generated in each stage, from raw material mixing, hot refining, calendering, molding to vulcanization. This waste gas mainly contains harmful substances such as benzene, toluene, xylene, non-methane hydrocarbons, and sulfides, which are highly irritating, volatile, and toxic. Therefore, it is necessary to treat the exhaust gas generated from rubber products. Exhaust gas treatment devices in the rubber industry are mainly based on various physical, chemical, and biological principles, employing advanced technologies to purify the exhaust gas.

[0003] A search revealed Chinese Patent Publication No. CN210532405U, which discloses an SBS rubber exhaust gas collection and treatment device, comprising an exhaust gas pretreatment tank and a reactor. A first air inlet is installed on the lower left side wall of the exhaust gas pretreatment tank, and a water inlet is installed on the upper left side wall of the exhaust gas pretreatment tank. Inside the exhaust gas pretreatment tank, from bottom to top, a first filter screen, a spray device, and a second filter screen are respectively installed. A water storage tank is connected to the bottom of the exhaust gas pretreatment tank.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: activated carbon adsorption is commonly used in exhaust gas treatment to adsorb harmful substances in the exhaust gas. However, the activated carbon is often discarded after adsorption saturation, resulting in a significant waste of activated carbon particles because it cannot be reused.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a waste gas treatment device for the rubber industry.

[0024] like Figure 1-4 As shown, a rubber industry exhaust gas treatment device includes a fixed frame 2, in which a heating mechanism is provided. The heating mechanism includes a heating wire 3 and a temperature controller 9. The heating wire 3 is installed on one side of the fixed frame 2, and the heating wire 3 is electrically connected to the temperature controller 9.

[0025] Please see Figure 1 The fixed frame 2 has an exhaust gas connection pipe 1 and an air inlet pipe 10 passing through its two sides respectively. One end of the exhaust gas connection pipe 1 is equipped with an exhaust gas connection pipe connector 100, and one end of the air inlet pipe 10 is connected to the air inlet end of the air pump 11. The air pump 11 is connected to an external power supply. The air pump 11 draws the exhaust gas from the exhaust gas connection pipe 1 into the fixed frame 2, and at the same time, it flows from the air inlet pipe 10 into the air inlet end of the air pump 11, and discharges the filtered gas from the exhaust end.

[0026] Please see Figure 2 A slot 24 extends through one side of the fixed frame 2, into which a plate 21 is inserted. A sealing ring 210 is installed on the plate 21, and a pull ring 211 is installed on one side of the plate 21. A sealing cover 20 is installed on the top of the fixed frame 2. The sealing cover 20 and the plate 21 form a placement cavity between the fixed frame 2. Circular activated carbon particles are placed on the plate 21. When the exhaust gas in the exhaust gas connection pipe 1 flows into the placement cavity, the circular activated carbon particles adsorb the substances in the exhaust gas.

[0027] Please see Figure 2 and Figure 3A ventilation hole 22 runs through one side of the fixed frame 2. The heating wire 3 and temperature controller 9 are both externally powered. The fixed frame 2 consists of a sealing cover 20, an insert plate 21, a ventilation hole 22, support legs 23, and a slot 24. Support legs 23 are fixedly connected to both sides of the fixed frame 2. An inner frame 4 is placed inside the fixed frame 2. A strainer 5 is fixedly connected to the middle of the inner frame 4. A door 6 is rotatably connected to the bottom of the inner frame 4. Brackets 7 are fixedly connected to the four corners of the door 6. Bolts 8 are threaded onto the brackets 7 and extend to the four corners of the bottom of the fixed frame 2. Circular activated carbon particles saturated with exhaust gas adsorption are placed on the strainer 5. Heating by the heating wire 3 will generate heat between the bottom of the insert plate 21 and the top of the door 6. When the circular activated carbon particles are heated, the surface temperature of the circular activated carbon particles will rise. During this process, the adsorbed substance molecules will gain... More heat energy enhances their mobility. As the temperature rises, these molecules gradually overcome the adsorption force on the surface of activated carbon and desorb from the activated carbon, falling onto the gate 6. This is the desorption method of round activated carbon particles. The heating wire 3 desorbs the adsorbed substances from the round activated carbon particles, enabling the reuse of round activated carbon particles and reducing processing costs. At the same time, heating the round activated carbon particles gives some unreacted raw materials the potential for reuse, thus realizing the advantage of reuse. Meanwhile, the temperature controller 9 controls the temperature of the heating wire 3. The ventilation holes 22 generated waste gas during the activated carbon desorption process. This waste gas may contain harmful substances or pollutants. The ventilation holes 22 can discharge this waste gas into the closed space, preventing the waste gas from accumulating in the closed space, thereby reducing harm to the environment and human body.

[0028] Please see Figure 4 The bottom surface of the door 6 is fixedly connected to a handle 60. The vertical projection of the pull ring 211 is a "U" shaped structure. By unscrewing the bolt 8 from the fixed frame 2, the inner frame 4 and the strainer 5 can be removed from the fixed frame 2. The round activated carbon particles after removal accumulate in the strainer 5. Flipping the door 6 causes the unreacted raw materials in the door 6 to fall into the recovery tray. At the same time, shaking the strainer 5 causes some unreacted raw materials in the strainer 5 to fall from the strainer 5 into the recovery tray.

[0029] The implementation principle of a rubber industry exhaust gas treatment device according to an embodiment of this application is as follows:

[0030] When the user turns on the heating wire 3, the heating wire 3 generates heat between the bottom of the insert plate 21 and the top of the tray 6. When the round activated carbon particles are heated, the surface temperature of the round activated carbon particles rises. During this process, the adsorbed molecules gain more heat energy, thereby enhancing their mobility. As the temperature rises, these molecules gradually overcome the adsorption force on the surface of the activated carbon and desorb from the activated carbon, falling onto the tray 6. This is the desorption method of round activated carbon particles. By heating the round activated carbon particles with the heating wire 3, the adsorbed substances are desorbed, enabling the round activated carbon particles to be reused, thereby reducing processing costs. At the same time, heating the round activated carbon particles gives some unreacted raw materials the potential for reuse, thus realizing the advantage of reuse. Meanwhile, the temperature controller 9 controls the temperature of the heating wire 3. The ventilation holes 22 generated during the activated carbon desorption process may contain harmful substances or pollutants. The ventilation holes 22 can discharge these waste gases into the enclosed space, preventing the waste gases from accumulating in the enclosed space, thereby reducing harm to the environment and human health.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
