Grid packing and packing structure

Abstract

The invention relates to grid packing and a packing structure. The grid packing comprises a plurality of grid plates which are arranged in parallel; each grid plate is provided with more than two through holes; a pipe spacer is arranged between every two grid plates; pull rods in a number corresponding to the number of the through holes alternately penetrate through the grid plates and the pipe spacers; both ends of each pull rod are provided with fastening pieces so that the grid plates and the pipe spacers are connected into a whole; each pull rod is a screw with threads at both ends; and each fastening piece is a nut which is in threaded connection with the screw. The packing structure applied to a packing tower comprises a plurality of layers of grid packing which is arranged vertically; the grid plates of the grid packing are perpendicular to the cross section of the packing tower, and two vertical adjacent layers of the grid packing are staggered and arranged at 45 degrees. The grid plates of the grid packing have small thickness, smooth surfaces, stable integrity, large specific surface area in use, strong anti-clogging capability, little resistance and long service life, thereby being practical, high-efficiency and energy-saving packing.

Description

(1) Technical field [0001] The invention relates to a grid filler and a filler structure, which breaks the traditional concept of filler structure. The airflow and liquid flow of all filler structures are cross-flow through the filler, while the airflow and liquid flow of the grid filler are advection flow through the filler. According to the old saying "flowing water does not rot", for the medium that is easy to block the tower, the sediment is carried away with the liquid flow through the continuous washing of the air flow and liquid flow, so the packing will not be blocked, thus solving the most difficult problem in chemical production The world problem "tower blocking". (2) Background technology [0002] my country's primary energy is mainly coal, and chemical fertilizers, methanol, gas and other projects are all made of coal, and the purification process of dust removal, cooling, and desulfurization is a key process. At present, both foreign and domestic desulfurizatio...

Problems solved by technology

Low desulfurization efficiency

If the coal quality is poor, the purification effect is often not achieved. The gas cooling and dust removal adopts empty tower spraying, and the cooling effect is not good, which makes the post-process purification more difficult.

Using random packing (such as Haier ring or structured plate corrugated packing), the resistance is large, the air flow and liquid flow through the packing layer are cross-flow, there are many sediments, it is often easy to block the tower, the service cycle is short, and it often needs to be used after a period of production. Parking for cleaning affects the normal production of synthetic ammonia
