Octagonal sieve plate net used for gas-liquid treatment device

Abstract

The invention provides an octagonal sieve plate net used for a gas-liquid treatment device. The octagonal sieve plate net used for the gas-liquid treatment device comprises at least one mesh unit and connecting pieces for fixing the mesh units. Each mesh unit comprises two substrates and a plurality of core tubes arranged between the two substrates; each core tube is an octagonal tube with an octagonal through hole. According to the octagonal sieve plate net used for the gas-liquid treatment device, on the basis of keeping the advantages of a traditional sieve plate net, length which is greater than the depth and the perimeter of section of each through hole is increased, and the density of the through holes in unit area is increased. When the octagonal sieve plate net used for the gas-liquid treatment device is used, a plurality of sieve plates are arranged in parallel according to the actual requirement, and meshes of two adjacent sieve plates are superposed in the manner of staggering to form an octagonal long and thin skew bending runner; when a gas-liquid mixture passes through the octagonal long and thin skew bending runners, not only can an effect of refining the gas-liquid mixture be performed but also the contact residence time between gas and liquid can be prolonged, and thereby, the purification efficiency is greatly increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to a component of a gas-liquid treatment device, in particular to an octagonal sieve plate net used in the gas-liquid treatment device. Background technique [0002] Usually, the harmful gas containing dust is treated by a two-step method. Firstly, the particulate materials in the gas are removed by electrostatic dust removal or bag dust removal, and then the harmful gas is treated by wet method. As disclosed in CN1712105A, the "method and device for purifying gas with liquid-phase medium" is a relatively advanced technology for wet separation of gas mixtures. Upward and impacting the upper sieve mesh, when passing through the sieve mesh, the gas and the liquid can be fully contacted, and the purification efficiency of the gas is greatly improved. [0003] The sieve mesh used to fully contact the gas and liquid usually has two structures. One structure is a conventional woven mesh. Although the density of holes per unit area is ...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is: in order to solve the limited length of the flow channel formed by the through hole of the core tube of the sieve mesh of the existing gas-liquid treatment device and the length of the section perimeter of the through hole, the distance between adjacent through holes The distance is large, resulting in the limited effect of refining the gas-liquid mixture. The present invention provides an octagonal sieve mesh for gas-liquid treatment devices. The mesh unit with octagonal through holes is used to solve the above problems.
