　　Separation tower stainless steel new solid valve tray metal tray tower internals

　　Structure and components of stainless steel valve tray:

　　1. The fixed valve tray is a semi elliptical valve body directly stamped from the tray body, and its projection on the tray is trapezoidal. This structural form is conducive to reducing the liquid level gradient and minimizing liquid backmixing on the tray. The size of the fixed valve can be produced according to the process conditions inside the tower, and can be stamped into different lengths such as 60mm, 30mm, 20mm, etc.

　　2. A fixed valve tray with similar structure, the smaller the size of the valve type, the lower the entrainment of mist and foam, and the higher the mass transfer efficiency; The smaller the ratio of valve gap area to valve hole area, the higher the pressure drop of the thousand plate and wet plate, and the less liquid leakage. Therefore, the smaller the valve size of the solid valve tray, the higher the processing capacity.

　　3. Fixed valve tray has low cost and imitates the shape of a valve. The fixed valve is directly decompressed from the tray plate. Due to the absence of moving parts, the wear and adhesion of the valve disc are eliminated, but compared to other floating valve trays, its lower limit of operating elasticity will be affected. However, solid valve trays have a higher upper limit of operational flexibility and processing capacity than sieve trays. The characteristic of solid valve tray is anti clogging, which has advantages for working conditions such as fermentation mash, washing tower, etc. that contain solid substances and are prone to fouling and blockage.

　　On April 13, 2022, our company bid for a project of a certain company in Fujian. Overview:

　　Project Name: Fujian Fuhai Chuang Petrochemical Co., Ltd. Raw Material Adaptability Technical Renovation Project, Condensation Oil Separation Unit and Vacuum Distillation Defect Elimination Renovation Project, Tower Components

　　Project scale: Raw material adaptability technical renovation project, including the construction of 2 million tons/year aromatic hydrocarbon adsorption and separation unit, 600000 tons/year liquefied gas separation unit, 500000 tons/year dry gas separation unit, 2 * 60000 tons/year recovery unit, 500000 tons/year heavy aromatic hydrocarbon lightweighting unit, 1.5 million tons/year fluidized bed residue hydrogenation unit, and the renovation of existing units (including the continuation of extraction unit, energy-saving and emission reduction renovation of reforming four in one heating furnace, etc.), as well as the corresponding supporting renovation of public works and auxiliary facilities. Most of the tower internals in this project use differential float valve trays.

　　Dier Chemical Packing Co., Ltd. was established in 2004 in Pingxiang City, Jiangxi Province. It is a key centralized enterprise for the production of chemical packing materials under the former Ministry of Chemical Industry. It is a member of the National Chemical (Technology, Information) Center Station, a member of the China Petroleum and Chemical Survey and Design Association, and a network cooperative enterprise of central enterprises such as PetroChina, Sinopec, ChemChina, and CNNC The company launched the second phase of the new environmentally friendly packing and tower internals equipment project in July 2017, located in the New Third Board Industrial Park of the development zone. It covers an area of 45 acres, with a total investment of 100 million yuan, a registered capital of 98 million yuan, fixed assets of 50 million yuan, and more than 200 employees, including 26 middle and senior technical personnel.

　　We produce 18 series and over 100 types of products including metal, ceramic, plastic fillers, tower internals, and chemical equipment. We have also hired four chemical tower design PhDs from Tsinghua University, Tianjin University, South China University of Technology, and Zhejiang University of Technology to provide strong technical support for the company's product quality, tower internals design, production, and new product development. There are more than 20 independently invented patents, which meet the needs of serving chemical and environmental protection enterprises. They produce a series of tower internals and chemical packing products, which are sold to coking and chlor alkali, fertilizer, chemical, salt, pharmaceutical, refining, power, environmental protection, coking and other manufacturers across the country with good usage effects. In 2008, they obtained the self operated import and export rights for foreign trade, and their products are exported to more than ten countries including Israel, France, the United States, South Korea, Germany, Brazil, Japan, etc.
