Abstract
Description
Technical Field
[0001] The utility model relates to the field of gas recovery and utilization, and in particular to a gas recovery and utilization device for improving gas purity. Background Art
[0002] Chemical gases are produced during chemical production, and some of the gases contain toxic gases. Irritant gases are toxic gases commonly encountered in chemical production. There are many types of irritant gases, the most common of which are chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide and dimethyl sulfate. Therefore, it is necessary to purify the chemical gases and recycle the purified gases for reuse. However, the existing gas recycling devices cannot purify harmful gases, thereby reducing the purity of the gas. Therefore, it is urgent to design a gas recycling device that can improve the purity of the gas.
[0003] For example, a Chinese patent with authorization announcement number CN210905482 discloses a chemical gas recovery device, including a recovery tower, a cyclone separator, a filter tower, a filter element, a packing layer, a distributor, a first storage tank, a distillation tower and a second storage tank. A cyclone separator is provided on one side of the recovery tower, and the gas outlet of the cyclone separator is connected to the gas inlet of the recovery tower through a pipeline. A filter tower is provided on one side of the recovery tower, and the exhaust port of the recovery tower is connected to the gas inlet of the filter tower through a pipeline. The chemical gas recovery device can recover organic solvent molecules in the chemical gas, but the chemical gas recovery device can only remove solid impurities in the gas before recycling the gas. Since the chemical gas contains a large amount of harmful gases, the gas recovery device cannot purify the harmful gases, thereby reducing the purity of the gas, which is not convenient for subsequent utilization of the gas.

[0032] The specific working principle of the purification mechanism 7 is as follows: first, the servo motor 702 is started by the control panel 5 (containing a PLC controller), and the connecting rod 703 is driven to rotate by the output shaft of the servo motor 702, and the rotating block 1 704 is driven to swing, and the rotating shaft 705 is driven to swing through the rotating block 1 704, and the rotating block 2 706 is driven to swing.

[0035] In practical application, first, when it is necessary to remove harmful gases in the gas, the gas to be treated is first introduced into the air inlet chamber 6. When the gas enters the gas purification tank 2 from the air inlet 10, it first contacts the guide plate 13. Under the guidance of the guide plate 13, the gas flows downward, and then bypasses the bottom of the guide plate 13 and enters the bottom of the activated carbon layer support 14, so that the gas flows upward in an S shape along the bottom surface of the activated carbon layer support 14 from the gap between two adjacent activated carbon layer supports 14. Since the activated carbon layer is arranged on the surface of the activated carbon layer support 14, the gas and the activated carbon on the surface of the activated carbon layer support 14 are The contact area of the layer is increased, so that harmful gases can be adsorbed more effectively. When the treated gas rises to the top of the gas purification tank through the through hole, the adsorbent can be sprayed through the purification mechanism 7 (the working principle of the purification mechanism 7 is as shown above), so that the gas entering the top of the gas purification tank 2 is fully in contact with the adsorbent, and the harmful gas is further purified.

Since the activated carbon layer bracket 14 and the inner wall of the gas purification tank 2 have a certain inclination, the gas will rise along the inclined surface to achieve the effect of dispersing the gas, thereby increasing the contact area between the gas and the activated carbon layer on the surface of the activated carbon layer bracket 14, thereby enabling the harmful gas to be more effectively adsorbed; the utility model can spray the adsorbent by setting a purification mechanism 7, so that the gas entering the top of the gas purification tank 2 is in full contact with the adsorbent, further realizing the purification of the harmful gas, thereby improving the gas purity and facilitating the recycling of the gas; the utility model can cool the gas in the gas storage tank 3 under the cooperation of the cooler 8 and the cooling pipe 9, thereby realizing continuous cooling of the gas, thereby ensuring the effective recovery of the gas, and by setting the temperature sensor 17, the temperature change inside the gas storage tank 3 can be detected in real time.
