A plastic structured packing

Abstract

The invention relates to a new type of plastic structured packing, which aims to break the disadvantages of poor wettability and low mass transfer efficiency of traditional plastic packing, improve the inherent manufacturing and processing mode, and combine corrugated sheets of different thicknesses and plastic wires of different wire diameters. Plastic plate corrugated packing with higher mass transfer efficiency and more precise plastic wire mesh packing are made by superposition and mixing, and the water and air distribution performance of the packing is enhanced through special treatment of the surface of the corrugated sheet. Can be widely used in petroleum, chemical, biological, pharmaceutical, environmental protection and other fields. The new type of plastic structured packing is made of a certain thickness of plastic plate into a plate corrugated sheet with plastic ribs; plastic wires of different wire diameters are used to make single-layer, double-layer or multi-layer plastic wire with a plastic skeleton. The mesh is further processed into corrugated sheets of different corrugated configurations by heating the plastic sheet and the wire mesh sheet, and the surface of the corrugated sheet is roughened by using a cutting tool.

Description

technical field [0001] The invention relates to a novel plastic structured packing, specifically a novel plastic plate corrugated packing and a novel plastic mesh corrugated packing, belonging to the field of gas-liquid mass transfer equipment in the chemical separation process. Background technique [0002] In the field of mass transfer and separation engineering, towers are very important mass transfer and separation equipment. As a kind of tower equipment, packed tower has a very wide range of applications, covering many fields such as petroleum, chemical industry, biology, medicine, environmental protection, etc. It has the advantages of large flux, low pressure drop, high efficiency, and energy saving. Packing, as the core component of the packed tower, plays an extremely important role in the transfer of mass, energy and momentum between gas-liquid or liquid-liquid. According to the structure and packing method, packing types are divided into structured packing and ra...

Problems solved by technology

Generally, the plastic fillers available on the market are made by rolling plastic plates, mostly corrugated and the thickness of the plates is uniform, which cannot effectively promote the turbulence of the liquid phase; As a result, the filler has a large porosity, low mass transfer efficiency, poor separation effect, and poor film-forming properties on the plastic surface, which is not conducive to the formation and renewal of liquid films, thus limiting the application range of plastic fillers
