Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment, and in particular to a high-throughput zeolite rotor waste gas adsorption and concentration device. Background Technology

[0002] Combustion VOCs devices are a common type of equipment used to treat VOCs gases. Through high-temperature combustion, volatile organic compounds (VOCs) can be converted into water and carbon dioxide. With the rapid development of China's economy, VOCs emissions will also increase. VOCs can combine with other pollutants in the air, thereby damaging the human respiratory tract and even inducing cancer in severe cases. Therefore, there are more and more VOCs treatment devices available.

[0003] In the prior art, patent document with publication number CN222256616U discloses a zeolite rotor adsorption concentration regenerative combustion device, including a heat-insulating box, a zeolite rotor housing fixedly connected to one side of the inside of the heat-insulating box, a cavity opened on one side of the inside of the zeolite rotor housing, and a zeolite rotor body rotatably connected inside the zeolite rotor housing.

[0004] During use, it was found that the above-mentioned device has a cumbersome filter replacement procedure and is not very convenient. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-throughput zeolite rotor waste gas adsorption and concentration device.

[0006] This utility model relates to a high-throughput zeolite rotor waste gas adsorption and concentration device, comprising a shell, an air inlet, a partition, a first air outlet, and a second air outlet. The partition inside the shell divides the interior into a desorption chamber and an adsorption chamber. An air inlet is located at the left end of the shell, communicating with the adsorption chamber. A first air outlet and a second air outlet are also located at the left end of the shell; the first air outlet communicates with the desorption chamber, and the second air outlet communicates with the adsorption chamber. A zeolite rotor assembly is mounted on the partition, and the desorption assembly is installed in the desorption chamber. A filter screen assembly is detachably mounted on the air inlet. At that time, the exhaust gas is filtered for particulate impurities by the filter screen assembly on the air inlet. When the exhaust gas passes through the zeolite rotor assembly, VOCs are adsorbed. The purified gas is sent to the next process through the No. 2 air outlet. Then, the zeolite rotor assembly is rotated, so that the part of the adsorbed VOCs gas moves to the desorption chamber. The desorption assembly is activated to heat the zeolite rotor assembly, so that the adsorbed VOCs gas is desorbed and sent to the next process through the No. 1 air outlet. This realizes that the large volume and low concentration of organic waste gas is converted into small volume and high concentration of organic waste gas after adsorption purification and desorption.

[0007] Preferably, the zeolite rotor assembly includes a frame, a zeolite rotor body, a gear ring, a motor, and gears. The frame is mounted on the partition plate, with its top in the desorption chamber and its bottom in the adsorption chamber. The zeolite rotor body is rotatably mounted inside the frame, and a gear ring is mounted on the outer wall of the zeolite rotor body. The motor is mounted at the bottom of the adsorption chamber, and a gear is mounted on the motor, meshing with the gear ring. In the adsorption chamber, the zeolite rotor body adsorbs VOCs from the waste gas. Starting the motor causes the gear to drive the zeolite rotor body to rotate via the gear ring, thus switching the zeolite rotor body between its active and passive positions. The portion of the zeolite rotor body that has adsorbed VOCs undergoes desorption in the desorption chamber, while the portion that has not adsorbed VOCs continues to adsorb VOCs in the adsorption chamber, improving operational efficiency.

[0008] Preferably, the desorption assembly includes a mounting base and a hot and cold air unit. The mounting base is installed on the top of the partition plate, and the hot and cold air unit is installed on the mounting base. The hot and cold air unit is operated to blow hot air onto the zeolite rotor body, thereby desorbing VOCs onto the zeolite rotor body. After desorption is completed, the hot and cold air unit is operated to blow cold air onto the zeolite rotor body to regenerate the zeolite rotor body.

[0009] Preferably, the filter assembly includes a support frame, a filter screen, a positioning plate, and bolts. The air inlet has a socket at its top. The filter screen is housed inside the support frame, and the positioning plate has a round hole at its top. The air inlet has a threaded groove at its top. The bolts pass through the round hole and are threadedly connected to the threaded groove. The support frame is inserted into the air inlet through the socket, and the bolts pass through the round hole and are threadedly connected to the threaded groove. The filter screen filters particulate impurities from the exhaust gas, improving the ease of replacement.

[0010] Preferably, it also includes a handle, with a handle installed at the top of the positioning plate; the operator can use the handle to pull out the positioning plate and the filter screen, improving convenience.

[0011] Preferably, the filter screen is made of stainless steel.

[0012] Preferably, it also includes a handle cover, on which the handle is fitted with a handle cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the exhaust gas is filtered for particulate impurities through the filter screen assembly on the air inlet, and VOCs are adsorbed when the exhaust gas passes through the zeolite rotor assembly. The purified gas is then transported to the next process through the No. 2 air outlet. After that, the zeolite rotor assembly is rotated, so that the part of the adsorbed VOCs gas moves to the desorption chamber. The desorption assembly is started to heat the zeolite rotor assembly, so that the adsorbed VOCs gas is desorbed and transported to the next process through the No. 1 air outlet. This realizes that large volume and low concentration of organic waste gas are converted into small volume and high concentration of organic waste gas after adsorption purification and desorption.
