Description

Technical Field

[0001] This utility model relates to the field of tail gas treatment technology, and more specifically, it relates to a tail gas treatment device for benzyl alcohol production. Background Technology

[0002] Benzyl alcohol, also known as benzyl alcohol, is an organic compound with the chemical formula C7H8O. It is one of the simplest aromatic alcohols and can be considered as methanol substituted with a phenyl group. It is a colorless, transparent liquid with a faint aromatic odor, slightly soluble in water, and readily soluble in organic solvents such as ethanol and ether. In nature, benzyl alcohol mostly exists in the form of esters in essential oils, such as jasmine oil and hyacinth oil. Furthermore, it is widely used in fragrances, cosmetics, pharmaceuticals, and paint solvents, among other fields.

[0003] Benzyl alcohol production generates a large amount of tail gas. To avoid the environmental impact of this tail gas, most existing systems use activated carbon to absorb and purify it. To ensure the purification effect of the activated carbon, it needs to be replaced regularly. However, the activated carbon in existing systems is often inconvenient to replace, and in some cases, it even requires shutdown for replacement, causing interruptions in tail gas treatment and affecting treatment efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tail gas treatment device for benzyl alcohol production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tail gas treatment device for benzyl alcohol production, comprising an outer shell and a drive mechanism;

[0006] One end of the outer shell is connected to an air inlet pipe, and the other end of the outer shell has a replacement port. A vertical shaft is rotatably connected to the outer shell, and an inner rotating body is fixedly connected to the vertical shaft. The inner rotating body has multiple cavities, and multiple activated carbon filter cartridges are installed in each cavity. The filter chamber of each activated carbon filter cartridge is connected to a conveying hole, and multiple conveying holes are opened on the inner rotating body. The outer shell has multiple exhaust holes, and each exhaust hole is connected to a conveying hole.

[0007] The drive mechanism is mounted on the outer casing and is used to drive the vertical shaft to rotate.

[0008] Preferably, the ends of the plurality of exhaust holes away from the conveying holes are all connected to the collection cover, the collection cover is fixedly connected to the outer shell, and the collection cover is connected to an exhaust pipe.

[0009] Preferably, the drive mechanism includes a driven gear, a driving gear, and a motor. The driven gear is fixedly connected to a vertical shaft, and a driving gear is meshed on the driven gear. The diameter of the driving gear is smaller than the diameter of the driven gear. The driving gear is fixedly connected to the output shaft of the motor, and the motor is mounted on the housing.

[0010] Preferably, a sealing gasket is fixedly connected to the inner wall of the outer shell, and the inner rotating body rubs against the sealing gasket.

[0011] Preferably, a plurality of support legs are fixedly connected to the outer shell.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The intake pipe is connected to a cavity, and the two exhaust ports are connected to two conveying ports respectively. The exhaust gas can be sent into the cavity through the intake pipe. After being filtered by multiple activated carbon filter cartridges in the cavity, the exhaust gas can be discharged sequentially through the conveying ports and exhaust ports, thus completing the absorption and purification of the exhaust gas. The drive mechanism drives the vertical shaft to rotate, and the vertical shaft drives the inner rotating body to rotate 180 degrees, so that the two cavities can be periodically interchanged. This allows the activated carbon filter cartridges in the two cavities to alternately absorb and purify the exhaust gas. The activated carbon filter cartridge that has been rotated to the replacement port can be replaced, making replacement more convenient and eliminating the need to stop the machine to interrupt the exhaust gas purification process, effectively improving the exhaust gas treatment efficiency.
