Problems solved by technology

Due to accidents such as operating errors, the flow rate and pressure will change suddenly, so after the internal fixed adsorption bed is impacted, the wire mesh will be overturned together with the adsorbent, resulting in the mixing of various adsorbents, resulting in the adsorption of adsorbents. Accidents such as failure and shutdown of air separation equipment have caused great losses

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with accompanying drawing: shown in Fig. 2-Fig. The perforated plates 4 are connected to each other, and at least one layer of wire mesh 5 is laid on the bottom surface of each perforated plate 4 . The perforated plate 4 is made by punching a thin metal plate, and the punching rate is between 10-80%. The bottom surface of the perforated plate 4 is punched, and at least two sides are provided with folded edges. The perforated plates 4 are connected by bolts 6 and nuts 7 , while the perforated plates 4 and the wire mesh 5 are connected by rivets 8 . The wire mesh 5 laid on the bottom surface of the porous plate 4 is provided with holes smaller than the adsorbent particles in the upper layer.

[0014] A metal barrier to prevent the upward punching of the porous plate is welded on the adsorber shell at a position less than 100 mm above the porous plate. It is used to prevent the perforated plate from c...

Abstract

An isolation plate device for isolating absorbent in absorber is prepared as forming isolation plate between top and bottom absorbent by connecting multiple porous plate, arranging at least one layer of metal wire screen at bottom surface of each porous plate, connecting porous plates by bolt and nut and connecting porous plate with said screen by rivet, preparing porous plate by punching metal thin plate and setting punched hole ratio on porous plate to be 10-80%, welding metal blocking matter on absorber shell at position less than 100mm above porous plate for preventing porous plate from moving-up.

Description

technical field [0001] The invention relates to a partition device specially used for separating adsorbents in an adsorber, in particular to a partition device used for partitioning adsorbents in an adsorber of an air separation plant in the cryogenic field. Background technique [0002] In the process of air deep freezing to produce oxygen or nitrogen, it is necessary to use adsorbents to adsorb the air to remove impurities such as moisture and carbon dioxide contained in the air. Adsorption treatment is to place various adsorbents inside the adsorber; in the prior art, the adsorbents 1 and 2 in the adsorber are separated by a layer of silk screen 3, as shown in Figure 1. Due to accidents such as operating errors, the flow rate and pressure will change suddenly, so after the internal fixed adsorption bed is impacted, the wire mesh will be overturned together with the adsorbent, causing various adsorbents to mix together, causing the adsorbent Accidents such as failure and ...
