[0002] The injection molding exhaust gas filtration and energy recovery device is an integrated environmental protection system that uses multi-stage purification technology to treat organic waste gas and dust generated during the injection molding process. At the same time, it recovers waste heat or braking energy to improve energy efficiency. The waste heat generated in the exhaust gas treatment can be recovered through a heat exchanger.

[0003] The waste gas generated during the injection molding process needs to be purified in a timely manner for reuse; otherwise, it will pollute the equipment and the air. However, the existing waste gas purification efficiency is low and the utilization of the filter liquid is limited, resulting in the residue of harmful gases in the waste gas. In view of the large amount of heat generated in the waste gas, the problem of energy recovery needs to be solved. Therefore, an injection molding waste gas filtration and energy recovery device is needed. Utility Model Content

The purification mechanism 3 includes a purification bottle 301 and a purification chimney 302. The purification bottle 301 is fixedly installed on the inlet pipe 1, and the purification chimney 302 is fixedly installed on the outlet pipe 2. Liquid guide pipes 303 are fixedly installed on both the upper and lower sides of the purification bottle 301, and an air guide pipe 304 is fixedly installed on the purification bottle 301. A motor 305 is fixedly installed on the lower side of the purification bottle 301, and a stirring shaft 306 is fixedly installed on the output end of the motor 305. Several filter plates 307 are fixedly installed in parallel inside the purification chimney 302.

[0018] One end of the air inlet pipe 1 is embedded in the purification bottle 301, and one end of the air inlet pipe 1 is located on the upper side of the purification bottle 301. One end of the air guide pipe 304 is embedded in the purification bottle 301, and one end of the air guide pipe 304 is located on the lower side of the purification bottle 301, so that the air guide pipe 304 is lower than the air inlet pipe 1. When liquid is injected into the purification bottle 301, the exhaust gas will pass through the liquid and then enter the air inlet pipe 1. The stirring shaft 306 is located between the air inlet pipe 1 and the air guide pipe 304 to ensure that the liquid inside the purification bottle 301 is stirred, so that the exhaust gas and the liquid are in full contact, thereby increasing the purification efficiency of the exhaust gas. A gap is left between the filter plates 307. The filter plates 307 can be removed and filter material can be added between them according to the exhaust gas purification requirements.

[0019] Example 2 See Figure 4 and Figure 5 A recovery mechanism 4 is provided between the air inlet pipe 1 and the air outlet pipe 2. The recovery mechanism 4 includes a water tank 401. A special-shaped pipe 402 is fixedly installed inside the water tank 401. An inlet pipe 403 is fixedly installed on one side of the water tank 401, and an outlet pipe 404 is fixedly installed on the other side of the water tank 401. Two connecting pipes 405 are fixedly installed side by side on one side of the special-shaped pipe 402.

[0020] The irregular tube 402 is composed of several S-shaped tubes, and there is a gap between the irregular tube 402 and the water tank 401 to increase the contact area between the irregular tube 402 and the water. The water inlet pipe 403 is located on the lower side of the water tank 401, and the water outlet pipe 404 is located on the upper side of the water tank 401, so that the water inlet pipe 403 is lower than the water outlet pipe 404, so that the water flows to fill the water tank 401 and then discharges through the water outlet pipe 404, thereby transferring the energy in the exhaust gas to the water. The irregular tube 402 is fixedly connected to the air inlet pipe 1 and the air outlet pipe 2 through the connecting pipe 405.

[0021] In actual operation, liquid that can purify waste gas is added into the purification bottle 301, and the motor 305 is controlled to rotate the stirring shaft 306 while the waste gas is input into the gas guide pipe 304, so that the waste gas comes into contact with the high-speed rotating liquid and the waste gas reacts fully with the liquid. A purification chimney 302 is installed on the gas outlet pipe 2, and materials that can purify waste gas are added between several filter plates 307. When the waste gas is removed from the gas outlet pipe 2, the harmful substances in the waste gas will be absorbed. By injecting cold water into the water inlet pipe 403, the water tank 401 is filled with cold water. When the exhaust gas is discharged from the air inlet pipe 1 through the shaped pipe 402 and the exhaust pipe 2, the energy in the exhaust gas will be released into the cold water, thereby heating the cold water. The device benefits from the shape of the shaped pipe 402, which makes more efficient use of the energy inside the exhaust gas.
