Product Introduction

One of the key equipment involved in the polysilicon project currently undertaken by our company is the silicon powder filter, with a total demand of 20 units. These filters play a vital role in the production process of polysilicon. They are mainly used to intercept the fine silicon powder generated in the production process, thereby purifying the raw gas and circulating process gas, ensuring the stability of the entire production process and the purity of the product.

In order to meet the high performance requirements of filters in polysilicon production, we specially selected Q345R+S31603 composite material. Q345R is a low-alloy high-strength steel with good comprehensive mechanical properties and welding properties. It can withstand high pressure and temperature and is suitable for manufacturing equipment such as pressure vessels. S31603 is a high-alloy austenitic stainless steel with excellent corrosion resistance, high temperature resistance and intergranular corrosion resistance. It is especially suitable for fields with extremely high corrosion resistance requirements such as chemical industry and marine engineering. Through the compound of Q345R and S31603, the filter not only has the dual advantages of high strength and corrosion resistance, but also can effectively reduce equipment costs while ensuring the service life and reliability of the equipment.

The design and manufacture of these silicon powder filters follow strict technical standards and can meet the requirements of polysilicon production for filtration accuracy, high temperature resistance, corrosion resistance and other aspects. Its filtration accuracy can reach micron level, which can effectively intercept tiny particles such as silicon powder and graphite powder to ensure the purity of the gas. In addition, the filter is equipped with an automatic backflush system, which does not require frequent opening of the equipment to replace internal parts, greatly reducing maintenance costs and leakage risks, and improving the operating efficiency and safety of the equipment.

In terms of application scenarios, these silicon powder filters are widely used in many key links of polysilicon production, including tail gas filtration in the silicon powder conveying process, synthesis gas filtration in the trichlorosilane synthesis process, and tail gas filtration in the trichlorosilane reduction process. Through efficient filtration performance, these devices can not only ensure the smooth progress of polysilicon production, but also effectively recover unreacted silicon powder and other valuable substances, improve resource utilization, and reduce environmental impact.

In short, the 20 silicon powder filters made of Q345R+S31603 provided by our company will provide a solid guarantee for the smooth implementation of the polysilicon project with their excellent performance and reliable quality, and help customers achieve higher efficiency and better economic benefits in the field of polysilicon production.
