Mass transfer heat exchange grill packing for washing dust collector

Abstract

The invention relates to a mass transfer heat exchange grill packing for a washing dust collector. The mass transfer heat exchange grill packing comprises multiple parallel corrugated plates, each one of folded peaks of the corrugated plates is provided with through holes with the same sizes and the same direction, all the through holes of each one of the folded peaks of the corrugated plates are arranged on the same plane, connection plates go through the through holes and connect the corrugated plates in series so that a corrugated packing block is formed. The through hole is in a shape of an arc with different diameters of two ends and the rectangular middle part, and the length of the through hole is the maximal distance of two end arc horizontal axial lines and is greater than the width of the connection plate. The connection plate is a rectangular plate with grooves, is provided with the upper groove and the lower groove at an interval, the horizontal distance of the adjacent grooves is a distance of the two adjacent corrugated plates and the width of the groove is greater than the thickness of the corrugated plate. The packing corrugated plate has a multifolded structure so that a specific surface area is improved, a structure is simple, installation is convenient and packing stability is improved. The mass transfer heat exchange grill packing improves dust trapping possibility, can be recycled and can greatly improve dedusting efficiency.

Description

technical field [0001] The invention relates to a packing, in particular to a mass transfer and heat exchange grid packing used for washing and dust removal devices in petrochemical, coal chemical, steel and other fields, which belongs to gas-liquid mass transfer equipment and is used for washing and dust removal devices. Mass transfer and heat exchange grid packing. Background technique [0002] In petrochemical, coal chemical, steel and other fields, in the process of gas purification, there are high requirements for washing, dust removal, and cooling, such as desulfurization towers, flue gas scrubbers, quenching towers, etc., the processed substances are usually dirty and contain A large amount of dust or tar requires the tower internals of the tower to have strong anti-clogging performance. In coal chemical industry, empty tower spray is used for gas cooling and dedusting, and the cooling effect is relatively poor, which makes the subsequent purification work more diffi...

AI Technical Summary

Problems solved by technology

However, the specific surface area of ​​the grid plate is small, and sufficient contact between the gas phase and the liquid phase cannot be achieved, and the cleaning effect is poor.

[0005] The purpose of the patent of this invention is to solve the problems of unsatisfactory dust removal, washing and cooling effects and easy blockage of the packing in the existing gas purification device, and propose a heat exchange grid packing for washing and dust removal device
