　　Customized production of 304 306L material Dier packing for distillation bubble cap tray

　　Composition of bubble tray:

　　The bubble cap tray is mainly composed of a tray with several bubble caps and ascending pipes, an overflow weir, a receiving tray, and a downcomer. The liquid flows from the upper tray through the downcomer, passes horizontally through the tray through the bubble cap, and enters the downcomer through the overflow weir. Steam enters the riser of the bubble hood from bottom to top, and is dispersed through the gaps between the bubbles into the liquid layer between the bubbles, fully contacting the liquid. The advantages are high production capacity, low clogging, and great operational flexibility. The disadvantage is the complex structure and significant reduction in gas-phase torque.

　　The function of bubble cap tray

　　Bubble cap trays are commonly used to bring vapor (or gas) into close contact with liquids to promote mass transfer between them. Inside the tower, there are multiple horizontal trays with several short tubes for steam (or gas) to pass through. Each tray is covered with bubble caps with gaps or small grooves at the bottom edge, and overflow pipes are installed. During operation, the liquid continuously enters from the upper part of the tower, descends plate by plate through the overflow pipe, and accumulates liquid layers on each plate, forming a liquid seal; Steam (or gas) enters from the bottom of the tower and disperses into small bubbles through the gaps or grooves on the bottom edge of the bubble cover. It fully contacts the liquid and passes through the liquid layer to reach the liquid surface, then rises to the upper tray. Short pipes installed inside the tower are called internal overflow type; There are also those installed outside the tower, called external overflow type. Bubble cap towers are widely used for distillation and gas absorption.

　　Advantages of bubble wrap tray:

　　The operation has greater flexibility and the tray is not easily blocked; The disadvantages are complex structure, high cost, thick liquid layer on the plate, high pressure drop on the tray, low production capacity and plate efficiency. There are three sizes of bubble caps: f80, f100, and f150mm, which can be selected according to the size of the tower diameter.

　　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 model in July 2017Environmentally friendly fillersThe project of tower internals equipment is located in the New Third Board Industrial Park of the development zone, covering 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. It produces 18 series and more than 100 types of products including metal, ceramic, plastic fillers, tower internals, and chemical equipment. At the same time, it has hired three chemical tower internals design PhDs from Tsinghua University, Tianjin University, and South China 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 chlor alkali, fertilizer, chemical, salt, pharmaceutical, refining, sulfuric acid, electricity, 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.
