Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a silicone rubber hot pressing waste gas purification and recovery device. Background Technology

[0002] Silicone rubber typically generates a large amount of harmful gases during hot pressing. These gases, if released into the air without treatment, can easily harm human health and the environment. Therefore, waste gas purification devices are usually required to treat the generated gases during the hot pressing process of silicone rubber.

[0003] In existing technologies, the treatment of waste gas from hot pressing of silicone rubber is usually carried out by activated carbon adsorption or catalytic combustion. The purification effect of a single waste gas treatment method is poor, and the exhaust gas still contains a lot of harmful substances. Moreover, the heat recovery effect during catalytic combustion is poor, which easily leads to resource waste. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a silicone rubber hot pressing waste gas purification and recovery device, which includes a combustion chamber and a waste gas treatment mechanism is provided on the top of the combustion chamber.

[0006] The waste gas treatment mechanism includes a preheating chamber with an inner layer inside the inner side wall. An air inlet pipe is connected through and fixedly connected to the upper right wall of the preheating chamber. A filter cartridge is provided in the middle of the outer periphery of the air inlet pipe. An installation groove is provided in the middle of the inner side wall of the filter cartridge. An activated carbon adsorption plate is fixedly connected to the inner side of the installation groove. An annular pipe is fixedly connected to the inner side wall of the preheating chamber. The preheating chamber is connected through and fixedly connected to the middle of the top wall of the catalytic chamber. A catalytic bed is fixedly connected to the top of the inner side of the catalytic chamber.

[0013] The beneficial effects of this utility model are:

[0014] 1. This silicone rubber hot pressing waste gas purification and recovery device starts the air pump when the waste gas generated during the silicone rubber hot pressing process needs to be treated. During the operation of the air pump, the gas to be treated is drawn through the air inlet pipe and enters the filter cartridge. The gas is pre-treated by the filter under the filter of the activated carbon adsorption plate. Then the gas enters the ring tube for preheating. After the preheated gas comes into contact with the catalytic bed for catalysis, it enters the combustion chamber for combustion, thereby improving the waste gas treatment efficiency and quality.

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a silicone rubber hot pressing waste gas purification and recovery device, which includes a combustion chamber 1 and a waste gas treatment mechanism 2 installed on the top of the combustion chamber 1.

[0024] The waste gas treatment mechanism 2 includes a preheating chamber 3. The inner wall of the preheating chamber 3 is provided with a sandwich layer 7. An air inlet pipe 4 is connected through and fixedly connected to the upper right wall of the preheating chamber 3. The air inlet pipe 4 can discharge untreated waste gas into the filter cartridge 5 and then into the annular pipe 8. The filter cartridge 5 is provided in the middle of the outer periphery of the air inlet pipe 4. An installation groove 16 is provided in the middle of the inner wall of the filter cartridge 5. An activated carbon adsorption plate 17 is fixedly connected to the inner side of the installation groove 16. The activated carbon adsorption plate 17 can adsorb and filter most of the harmful substances in the waste gas. The annular pipe 8 is fixedly connected to the inner wall of the preheating chamber 3. The annular pipe 8 can prolong the residence time of the gas in the preheating chamber 3, thereby ensuring that the gas can be preheated to the catalytic temperature. The preheating chamber 3 is connected through and fixedly connected to the middle of the top wall of the catalytic chamber 9. A catalytic bed 10 is fixedly connected to the top of the inner side of the catalytic chamber 9. The catalytic bed 10 is made of catalyst and can catalyze the waste gas.

[0025] A drain pipe 15 is connected and fixedly connected to the lower middle part of the left side wall of the interlayer 7. A water inlet pipe 13 is connected and fixedly connected to the upper middle part of the left side wall of the interlayer 7. The input end of the water inlet pipe 13 is connected and fixedly connected to the left middle part of the top wall of the hot water tank 12. A booster pump 14 is installed on the lower outer periphery of the water inlet pipe 13. During the operation of the booster pump 14, it can draw hot water from the inside of the hot water tank 12 and let it enter the interlayer 7 for heat exchange.

[0026] The drain pipe 15 is connected to the right side of the top wall of the hot water tank 12. The hot water tank 12 is connected to the left side of the top wall of the combustion chamber 1. The catalytic chamber 9 is connected to the middle of the top wall of the combustion chamber 1. The exhaust pipe 11 is connected to the right side of the top wall of the combustion chamber 1. The catalytic chamber 9 is the place for catalytic treatment of exhaust gas. The gas after catalysis enters the combustion chamber 1 for combustion.

[0027] The output end of the intake pipe 4 is fixedly connected to the input end of the annular pipe 8. The output end of the annular pipe 8 is located inside the catalytic bed 10. An air pump 6 is installed on the left side of the outer periphery of the intake pipe 4. The intake pipe 4 is located on the upper side of the exhaust pipe 11. The air pump 6 can extract the exhaust gas and discharge it into the annular pipe 8. The exhaust pipe 11 is controlled by a valve to open or close. When the valve is opened after the exhaust gas treatment is completed, the treated gas is discharged from the exhaust pipe 11.

[0028] Working principle: When the waste gas generated during the hot pressing of silicone rubber needs to be treated, the suction pump 6 is started. During the operation of the suction pump 6, the gas to be treated is drawn through the air inlet pipe 4 and enters the filter cylinder 5. The gas is initially treated by the activated carbon adsorption plate 17. Then the gas enters the annular pipe 8 for preheating, so that the waste gas reaches the catalytic temperature. After the preheated gas comes into contact with the catalytic bed 10 for catalysis, it enters the combustion chamber 1 for combustion. The heat generated in the combustion chamber 1 during the treatment of harmful gases is absorbed by the water in the hot water tank 12. At the same time, the booster pump 14 is started, so that high-temperature water is discharged from the water inlet pipe 13 into the jacket 7 for preheating treatment of waste gas.
