Description

Technical Field

[0001] This utility model belongs to the field of exhaust gas treatment technology, and in particular relates to a purification device for treating arsenic trichloride exhaust gas. Background Technology

[0002] Arsenic trichloride is an inorganic compound that is a toxic, colorless liquid. High-purity arsenic trichloride is used in the epitaxial and diffusion processes of semiconductor production. It can also be used as a solvent for iodine, phosphorus, alkali metal iodides and oils, as well as in the ceramics industry and for the synthesis of chlorine-containing arsenic preparations. However, the production process of arsenic trichloride generates some exhaust gases, which contain a certain amount of harmful substances and need to be treated to avoid environmental damage.

[0003] When treating exhaust gas, some manufacturers pass the exhaust gas into a treatment liquid to adsorb harmful substances from the exhaust gas. However, because the gas easily generates bubbles, it cannot fully contact the treatment liquid, thus failing to ensure complete treatment of harmful substances in the exhaust gas. Furthermore, it cannot be dispersed into the air in a timely manner during discharge. To solve these problems, there is an urgent need for a purification device for treating arsenic trichloride exhaust gas. Utility Model Content

[0004] The purpose of this utility model is to address the problem that some manufacturers introduce exhaust gas into a treatment liquid to adsorb harmful substances in the exhaust gas, but the gas is prone to generating bubbles, which prevents it from fully contacting the treatment liquid and thus cannot ensure the complete treatment of harmful substances in the exhaust gas. Furthermore, the gas cannot be dispersed into the air in a timely manner during discharge. Therefore, this utility model proposes a purification device for treating arsenic trichloride exhaust gas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a purification device for treating arsenic trichloride tail gas, comprising a base, a tank fixedly connected to the top of the base, an opening on the outer wall of the tank, a discharge component at the top of the tank, and a stirring component inside the tank.

[0006] The stirring assembly includes a motor, the output shaft of which is fixedly connected to a mounting shaft, a mesh plate is fixedly connected to the outer wall of the mounting shaft, an air jet disc is fixedly connected to the bottom of the tank, and an air inlet pipe is fixedly connected to the bottom of the air jet disc.

[0007] As a further description of the above technical solution:

[0008] The top of the motor is fixedly connected to the bottom of the tank, and the mounting shaft is rotatably connected to it through a through hole opened at the bottom of the tank.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the air intake pipe is fixedly connected to the opening, and the top surface of the jet disk is provided with multiple nozzles that are evenly distributed.

[0011] As a further description of the above technical solution:

[0012] The emission assembly includes a support rod, the bottom end of which is fixedly connected to an installation shaft, a fixing rod is fixedly connected to the outer wall of the support rod, and a nozzle is fixedly connected to the bottom end of the fixing rod.

[0013] As a further description of the above technical solution:

[0014] The top of the support rod is fixedly connected to a mounting cover, the outer wall of the mounting cover is fixedly connected to an exhaust pipe, and the top of the mounting cover is fixedly connected to a wind vane.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the mounting cover is rotatably connected to the top of the tank, and a support ring is fixedly connected to the inner wall of the mounting cover, with the bottom surface of the support ring in contact with the top of the tank.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by installing a mesh plate inside, when treating exhaust gas, the treatment liquid is poured into the tank, and at the same time, the motor is started to drive the mounting shaft to rotate, which in turn drives the mesh plate to rotate. Thus, the mesh plate stirs the treatment liquid and disperses the bubbles formed by the exhaust gas discharged from the jet plate. Through this design, when the jet plate discharges exhaust gas into the treatment liquid, the rotation of the mesh plate disperses the bubbles formed by the exhaust gas, thereby ensuring that the exhaust gas can fully contact the treatment liquid and thus treat the harmful substances in the exhaust gas.

[0019] 2. In this utility model, by providing an internal air baffle, during processing, the mounting shaft drives the support rod to rotate and the fixing rod to rotate, and the treatment liquid is sprayed out through the nozzle, thereby further bringing the treatment liquid into contact with the exhaust gas. At the same time, the support rod drives the protective cover to rotate, and the rotation of the protective cover drives the air baffle to rotate, thereby further dispersing the exhaust gas through the airflow driven by the rotation of the air baffle. Through this design, the treated exhaust gas can be dispersed when it is discharged, so that it can be quickly dispersed into the air, avoiding excessively high concentration at the outlet.
