Gas distribution structure and gas distributor

Abstract

A gas distribution structure and a gas distributor belong to the field of chemical equipment. The gas distribution structure includes a plurality of splitter plates, and the splitter plates include annular plates and conical baffles that are matched and connected to each other, and the conical baffles define a conical cavity. The ring plate has a plate hole, the ring plate is connected to the starting end and the plate hole communicates with the starting opening, a plurality of splitter plates are arranged in the form of channels formed at intervals along the preset direction, and the plate holes of each ring plate are opposite and communicated . The arc-shaped baffle has an arc-shaped convex surface, and the arc-shaped convex surface of the arc-shaped baffle corresponds to the plate hole of the annular plate facing the adjacent splitter plate. The gas distribution structure plays a high-efficiency diversion role for the flow of gas. The pressure of the gas in each channel is equal, the flow velocity is evenly distributed, and the resistance drop is small. After the gas enters the equipment through the distributor, it can quickly reach a uniform distribution state, and can achieve uniformity at the inlet cross section of the bed, with low air flow turbulence and back mixing, good uniform distribution effect, and low energy loss.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a gas distribution structure and a gas distributor. Background technique [0002] Gas The gas distributor is a very important equipment internal component. Gas distributors are widely used in towers, adsorption tanks, reactors and other equipment. The quality of its performance will have a huge impact on the gas uniform distribution effect and equipment performance in the equipment. The high-performance gas distributor can reduce the turbulence and turbulence of the high-speed fluid after entering the equipment, so that it can achieve the ideal level of uniform distribution in a shorter distance. High-performance gas distributors generally have the following characteristics: 1) The components of the gas source are evenly distributed and uniform at the inlet cross section of the bed; 2) The pressure drop generated when the fluid passes through the gas distributor is small and t...
