Description

Technical Field

[0001] The utility model relates to the technical field, and specifically relates to a vacuum suction system for phosphorus pentasulfide in industry. Background Technique

[0002] In the current industrial production process, especially in the fields related to high-precision electronics, semiconductor manufacturing, and special material processing, the requirements for environmental control are extremely high. Phosphorus pentasulfide, as an important chemical raw material, is widely used in the preparation of electrolytes for lithium batteries and the production of certain special lubricants and additives. However, phosphorus pentasulfide is prone to volatilization during use, and its vapor is not only harmful to the environment but also may pose a threat to the health of workers. Moreover, under certain conditions, its vapor may form an explosive mixture with air. Therefore, the handling of such chemical substances requires extreme caution.

[0003] Traditional phosphorus pentasulfide treatment equipment mostly uses ordinary exhaust systems for control, but these systems often have problems such as low efficiency and high safety risks. For example, traditional systems are difficult to completely isolate the external environment during the suction process, easily causing the leakage of harmful gases, which not only increases environmental pollution but also exacerbates the health threat to operators. In addition, the design of these systems often does not fully consider the characteristics of chemical gases, such as the high volatility and potential chemical activity of phosphorus pentasulfide. Therefore, improper operation may lead to safety accidents in some cases. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a vacuum suction system for phosphorus pentasulfide in industry, which solves some problems in the existing background technology.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: 1. A vacuum suction system for phosphorus pentasulfide in industry, including a reaction tank, a vacuum pump system, a gas-solid separation tank, a storage tank, and a tail gas treatment device. It is characterized in that the reaction tank A, reaction tank B, and reaction tank C are connected to the gas-solid separation tank through pipelines and the vacuum pump system. The pipeline material is a highly corrosion-resistant PTFE pipeline. The vacuum pump system includes a PTFE-coated rotary vane pump and a spare dry centrifugal pump. The gas-solid separation tank is connected to the storage tank and the tail gas treatment system through pipelines. The tail gas treatment system includes at least 3 sets, namely a chemical adsorption tower A and a tail gas combustion device A, a chemical adsorption tower B and a tail gas combustion device B, and a chemical adsorption tower C and a tail gas combustion device C.

[0006] Preferably, the reaction tank A, reaction tank B, and reaction tank C are connected to the gas-solid separation tank through pipelines and the vacuum pump system.

[0007] Preferably, the pipeline material is a highly corrosion-resistant PTFE pipeline.

[0008] Preferably, the vacuum pump system includes a PTFE-coated rotary vane pump and a standby dry centrifugal pump to ensure rapid replacement and stable operation of the system when needed.

[0009] Preferably, the gas-solid separation tank is connected to the storage tank and the tail gas treatment system through pipelines.

[0010] Preferably, there are at least three sets of the tail gas treatment system, namely, chemical adsorption tower A and tail gas combustion device A, chemical adsorption tower B and tail gas combustion device B, and chemical adsorption tower C and tail gas combustion device C. Advantages

[0011] The present utility model provides a vacuum suction system for phosphorus pentasulfide in industrial use, which has the following advantages: 1. A vacuum suction system for phosphorus pentasulfide in industrial use uses a PTFE-coated rotary vane pump and pipelines as the main vacuum pump system, which can effectively extract phosphorus pentasulfide vapor. The PTFE coating has excellent chemical inertness and corrosion resistance, and is suitable for handling toxic chemicals such as phosphorus pentasulfide. This choice not only ensures the long-term stability and performance of the pump, but also reduces the maintenance cost and leakage risk.

[0012] 2. Equipped with a standby dry centrifugal pump as a backup system, it can ensure the stable progress of the production process when the main pump fails or is under maintenance. The dry pump does not require oil lubrication, avoiding the problems of pollution and handling oil vapor, and at the same time has a high pumping rate and vacuum pumping efficiency, which is suitable for handling industrial-level vacuum requirements.

[0013] 3. For the solution after being treated by the chemical adsorption tower, if there are residual phosphorus pentasulfide or other pollutants, they can be further treated by the tail gas combustion device. This device can burn the residual substances at high temperature and convert them into harmless carbon dioxide and water, thus effectively reducing environmental pollution. Through the combined application of the chemical adsorption tower and the tail gas combustion device, the vacuum suction system for phosphorus pentasulfide in industrial use not only meets the requirements of environmental protection regulations, but also significantly reduces the treatment cost and resource consumption.

[0014] 4. After converting the phosphorus pentasulfide vapor into an organic solution through the chemical adsorption tower, the phosphorus pentasulfide can be recovered and utilized by methods such as extraction. This technology can reduce the raw material cost and improve the production efficiency through effective recovery and reuse. Description of the Drawings
