Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to a novel adsorption cylinder. Background Art

[0002] The semiconductor production process produces tail gas containing a variety of harmful chemicals, which need to be effectively treated to reduce the harm to the environment and personnel. Adsorption cylinder (also called adsorber, absorption column) is a common device for treating such tail gas. It uses specific adsorption materials (such as activated carbon, molecular sieve, silica gel or other special chemical adsorbents) to capture and remove harmful components in the tail gas.

[0003] As we all know, adsorption refers to the attachment of atoms, ions or molecules of a certain gas, liquid or dissolved solid to a surface. This process produces a film composed of adsorbates on the surface. Generally speaking, the larger the contact area between the exhaust gas and the adsorbent, the better the adsorption effect. In the prior art, the contact between the adsorbent inside the adsorption cylinder and the exhaust gas is often not sufficient, resulting in technical problems in the exhaust gas treatment effect. Utility Model Content

[0004] The utility model discloses a new type of adsorption cylinder, which solves the technical problem of poor tail gas treatment effect of the adsorption cylinder in the prior art, and has the technical effects of reasonable structure, good tail gas adsorption treatment effect and conducive to stable airflow output. The technical scheme adopted is as follows:

[0005] A new type of adsorption cylinder includes a cylinder body, wherein the two ends of the hollow cavity of the cylinder body are respectively connected to a first inlet and a first outlet, two rectifier plates are arranged in the hollow cavity of the cylinder body, a plurality of air holes are arranged on the two rectifier plates, the two rectifier plates and the cylinder body are combined to form an adsorption cavity for accommodating an adsorbent, and the rectifier plate close to the first inlet is recessed into the adsorption cavity and extends into the adsorption cavity.

[0006] On the basis of the above technical solution, the extension portion of the rectifying plate extending into the adsorption chamber gradually becomes smaller from the outside to the inside and forms a frustum.

[0007] Based on the above technical solution, the air holes on the extension portion extend along the thickness direction of the extension portion.

[0008] Based on the above technical solution, the end of the extension portion is spaced apart from the rectifying plate close to the first outlet.

[0009] On the basis of the above technical solution, a support plate is provided on the inner wall surface of the cylinder, and the support plate can abut against the rectifying plate upward and support the rectifying plate.

[0010] On the basis of the above technical solution, the inner end surface of the cylinder and the rectifying plate at the corresponding position form an air intake cavity, and the first inlet is provided in plurality and is centrally symmetrically arranged on the outer peripheral surface of the air intake cavity.

[0011] On the basis of the above technical solution, a plurality of observation windows are further provided on the cylinder body, and the observation windows are used to view the situation in the adsorption chamber.

[0012] On the basis of the above technical solution, it also includes a pressure sensor, which is used to monitor the air pressure in the adsorption chamber and is electrically connected to an external controller.

[0013] On the basis of the above technical solution, a mounting seat is fixedly connected downwardly to the cylinder body, and the mounting seat includes a plurality of universal wheels to facilitate the movement of the adsorption cylinder.

[0014] Beneficial Effects

[0015] The utility model has a reasonable structure. The adsorption chamber between the two rectifier plates is used to accommodate the adsorbent, and a rectifier plate part is extended inward to form an extension portion, so that the adsorbent can be arranged around the extension portion, and the exhaust gas entering through the air intake chamber can be evenly diffused into the adsorption chamber. In this way, not only can the exhaust gas be divided into more branch airflows, which is beneficial for the exhaust gas to fully contact with the adsorbent, but the arrangement of the adsorbent surrounding the extension portion can also increase the contact area between the airflow and the adsorbent, which is beneficial for improving the exhaust gas treatment effect. In addition, the air port on the extension portion extends along the thickness direction thereof, so that the gas path can better wrap the adsorbent and improve the adsorption treatment effect.

[0016] The extension portion in the utility model can also be conical, so that along the airflow direction, the larger the space occupied by the adsorbent, the more conducive to further reducing the airflow velocity and prolonging the contact time between the exhaust gas and the adsorbent. In addition, the extension portion and the rectifier plate on the outlet side are spaced apart, so that the adsorbent can completely cover the extension portion, which is conducive to improving the exhaust gas treatment effect.

[0017] In the utility model, two rectifying plates are placed on a supporting plate, which is convenient for taking and placing adsorbents and maintaining equipment, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1~2 The novel adsorption cylinder shown in FIG. 1 comprises a cylinder body 1, wherein two ends of the hollow cavity of the cylinder body 1 are respectively connected with a first inlet 11 and a first outlet 12. Figure 2 As shown, two rectifier plates 2 are provided in the hollow cavity of the cylinder 1, and a plurality of air holes are provided on the two rectifier plates 2. The two rectifier plates 2 and the cylinder are enclosed to form an adsorption chamber 200 for accommodating an adsorbent, wherein the adsorbent is the prior art and will not be described in detail here, such as activated carbon, molecular sieve, silica gel or other special chemical adsorbents, and those skilled in the art can select according to needs.

[0027] like Figure 2 As shown, the cylinder 1 is closed at one end and open at the other end, and the inner end surface of the closed end and the rectifier plate 2 at the corresponding position enclose an air inlet cavity 100. A plurality of first inlets 11 are provided and are symmetrically arranged on the outer peripheral surface of the air inlet cavity 100, so that the tail gas can enter the air inlet cavity 100 relatively evenly. The upward open end of the cylinder 1 forms a first outlet 12 for connection with subsequent process equipment.

[0028] like Figure 2 As shown, the rectifying plate 2 near the first inlet 11 is recessed into the adsorption chamber 200 to form an extension portion 3, and the extension portion 3 is axially arranged along the cylinder 2 and extends into the adsorption chamber 200. In addition, the air holes on the extension portion 3 extend along the thickness direction of the extension portion, so that the exhaust gas can "positively" impact the adsorbent, which is beneficial to reduce the gas flow rate and prolong the contact time between the exhaust gas and the adsorbent.

[0029] In addition, the end of the extension portion 3 is spaced apart from the rectifying plate 2 near the first outlet 12 , so that the adsorbent can fill the adsorption chamber 200 and completely cover the extension portion 3 , which is beneficial to improving the adsorption effect.

[0030] like Figure 2 As shown, an annular extending gap is formed between the two rectifying plates 2 and the inner wall of the cylinder 1 for air flow to pass through, which is beneficial to improving the air flow rectifying effect.

[0031] In other embodiments of the utility model, the extension portion 3 of the rectifier plate 2 extending into the adsorption chamber 200 gradually becomes smaller from the outside to the inside and forms a cone. In this way, the larger the space occupied by the adsorbent along the airflow direction, the more conducive it is to further reduce the airflow velocity and extend the contact time between the exhaust gas and the adsorbent.

[0032] A support plate 4 is provided on the inner wall surface of the cylinder 1. The support plate 4 is arranged corresponding to the position of the rectifying plate 2. The support plate 4 can abut against the rectifying plate 2 upward and support the rectifying plate 2. In addition, a plurality of observation windows 6 are provided on the cylinder 1. The observation windows 6 are used to view the situation in the adsorption chamber 200. Specifically, the observation windows 6 extend into the cylinder 1 and form a pipe extending into the cylinder 1. The pipe is provided with a plurality of through holes. When the airflow passes through the through holes and flows through the inner cavity of the pipe, the state of the airflow can be observed.

[0033] In addition, a pressure sensor is also included. The pressure sensor is used to monitor the air pressure in the adsorption chamber 200 and is electrically connected to an external controller. The pressure sensor is a prior art and can be selected by a person skilled in the art according to needs.
