Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment devices, in particular to a device for removing tar from tail gas of a vapor deposition furnace. Background Art

[0002] Vapor deposition is a common chemical reaction in industrial manufacturing, and the vapor deposition furnace is the most important equipment for this chemical reaction. The use of the vapor deposition furnace will produce a large amount of exhaust gas during the production process. There are a large number of harmful substances in the exhaust gas, tar being one of them. Therefore, an exhaust gas tar removal device is needed to treat the exhaust gas from the vapor deposition furnace.

[0003] In actual treatment, there are generally two ways to remove tar from the exhaust gas of a vapor deposition furnace: adsorption and condensation. The adsorption method removes tar from the exhaust gas through activated carbon, and the condensation method condenses the tar component into a liquid by lowering the exhaust temperature, thereby separating the tar. However, in the adsorption method, the activated carbons are piled together, so that the exhaust gas can only contact part of the activated carbon. The contact area between the activated carbon and the exhaust gas is limited, resulting in a poor effect of activated carbon on removing tar from the exhaust gas. Improvements should be made to this problem.

[0004] Therefore, a device for removing tar from tail gas of a vapor deposition furnace is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problems mentioned in the above background technology, and provide a device for removing tar from tail gas of a vapor deposition furnace.

[0010] Furthermore, the stirring rod is arranged in an L shape, and the stirring rod is adapted to the inner diameter of the activated carbon storage barrel.

[0011] Furthermore, the cooling assembly includes a cooling box, a cooling box is fixedly provided on the top of the box, a tube body is connected to the surface of the cooling box, and the other end of the tube body passes through the side wall of the box body and extends to the interior of the box body, and this end of the tube body is fixedly connected to a coil.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model pre-treats the exhaust gas through a pre-treatment component and the activated carbon inside the pre-treatment component, thereby preliminarily filtering the tar in the exhaust gas, and can filter the large particles of impurities in the exhaust gas.
