Description

Technical Field

[0001] This utility model relates to the field of ceramic filter element structure technology, and in particular to a reinforced structure for ceramic filter elements used in silicon waste gas treatment. Background Technology

[0002] With the rapid development of the silicon industry, such as the continuous expansion of polycrystalline silicon and monocrystalline silicon production scale, the emission of silicon waste gas is also increasing. This silicon waste gas contains pollutants such as dust and gaseous silicon compounds. If directly emitted into the atmosphere, it will cause serious environmental pollution, harm human health, and fail to meet environmental protection requirements. Therefore, effective waste gas treatment technologies and equipment are needed. Existing ceramic filter elements for silicon waste gas treatment are generally composed of ceramics, which adsorb impurities in the waste gas. However, they cannot guide the waste gas to flow evenly through all parts of the filter element. Some waste gas may pass through the treatment area quickly without undergoing sufficient physical or chemical reaction with the ceramic material, resulting in incomplete removal of harmful substances and affecting the waste gas treatment effect. Therefore, improvements are needed to address the above problems. Utility Model Content

[0008] Preferably, the ceramic tube is hexagonal, and multiple ceramic tubes abut against each other.

[0009] Preferably, the ceramic tube has an internal threaded groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the fan and the connecting ring facilitates the installation of the outer tube at the exhaust gas outlet and controls the flow direction of the exhaust gas, thereby improving the exhaust gas treatment efficiency; the cooperation between the ceramic tube and the internal thread groove facilitates the passage of exhaust gas through the internal thread groove, increases the contact area between the exhaust gas and the ceramic tube, increases the flow rate of the exhaust gas, and also improves the exhaust gas treatment effect.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-5The reinforced structure of the ceramic filter element for silicon waste gas treatment in this utility model includes an outer tube 2, inside which multiple equidistant ceramic tubes 4 are installed, and a connecting component is provided on the outside of the outer tube 2 to facilitate the flow of waste gas; the outer tube 2 facilitates the installation of multiple ceramic tubes 4; the ceramic tubes 4 facilitate the treatment of waste gas; the connecting component includes connecting rings 1 at both ends of the outer tube 2, and flanges 6 are fixed to the near ends of the connecting rings 1; the connecting rings 1 facilitate the connection of the outer tube 2 to other devices; the flanges 6 facilitate the installation of the connecting rings 1 on the outer tube 2; flanges 6 are installed on the outside of both ends of the outer tube 2, and both ends of the outer tube 2 are connected to the connecting rings 1 through the flanges 6; a cross is installed on the inside of the connecting rings 1, and a fan 3 is installed on the cross; the fan 3 facilitates the control of the direction and speed of waste gas flow; the ceramic tubes 4 are hexagonal, and multiple ceramic tubes 4 abut against each other; the ceramic tubes 4 have internal threaded grooves 5 inside; the internal threaded grooves 5 facilitate the increase of the contact area between the waste gas and the ceramic tubes 4, and increase the waste gas flow rate.

[0020] Working principle: When using this utility model, firstly, connecting rings 1 are installed at both ends of the outer pipe 2 through flanges 6, so that fans 3 are installed at both ends of the outer pipe 2. Then, the outer pipe 2 is installed at the exhaust gas outlet through connecting rings 1. When the exhaust gas enters the outer pipe 2 from the connection, it first contacts the fan 3, so that the fan 3 rotates. Through the rotation of the fan 3, the exhaust gas is driven to move into the outer pipe 2 along a rotation direction. Then, it contacts the inner thread groove 5 of the ceramic tube 4, and some of the exhaust gas will enter the groove of the inner thread groove 5, thereby increasing the contact area between the exhaust gas and the ceramic. Furthermore, the rotation of the inner thread groove 5 increases the flow speed of the exhaust gas in the ceramic tube 4. Finally, the treated exhaust gas flows out from the other end of the outer pipe 2.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
