Description
Technical field
The utility model relates to a kind of transformation adsorbed gas device, especially relates to a kind of transformation adsorbed gas device adsorption tower middle part collector.
Background technology
Following equal baric flow journey in the pressure swing adsorption gas separation device is all pressed all pressing the position to do improvement down because of it has not equipotentiality.The body of all calming the anger when all pressing is drawn the bottom of the adsorption tower that gets into the desorption end from the adsorption tower middle part that absorption finishes; Inverted pyramid type Gradient distribution characteristics according to nitrogen gas purity in the adsorption tower are all pressed; Like this that nitrogen gas purity is higher gas all is pressed onto desorber from adsorption tower; The intrinsic purity gradient of bed of having reduced distributes, and has improved the nitrogen gas concn of desorber, has reduced the preparatory absorption of the interior carbon molecular sieve of desorber to oxygen simultaneously; Improve the utilization rate of carbon molecular sieve, promptly improved the denitrification production rate of carbon molecular sieve.The structure that gas has become a kind of necessity of pressure swing adsorption gas separation device is got at the middle part, gets the gas device and be the steel pipe by outer surface boring, wraps steel wire then, and it is to get gas device and pressure vessel weldering extremely that depressed structure is got at traditional middle part, and on-dismountable, its shortcoming is following:
1. get the adsorption tower container production of gas device and transformation absorption and carry out synchronously, container is when welding, and welding slag possibly burn out steel wire, causes the molecular sieve in the adsorption tower to leak.
2. get the gas device after the steel wire fragmentation occurring, can't change.
Summary of the invention
The utility model mainly is to solve existing in prior technology to occur easily leaking, the technical problem that can't change, provide a kind of sealing reliable, change collector in the middle part of the device of the transformation adsorbed gas easily adsorption tower.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of transformation adsorbed gas device adsorption tower middle part collector; The middle part that it is characterized in that adsorption tower is provided with gets pore; This is got pore and gets gas flange neck and link to each other with one; And there is one to get tracheae and pass and get the gas flange and get pore and stretch into adsorption tower inside; Stretch into getting of adsorption tower interior section and be arranged with a mesh shade assembly on the tracheae, the described tracheae of getting is provided with an annular contiguous block, and this annular contiguous block links to each other through bolt with the described big end of getting the gas flange.The mesh shade assembly is got between the tracheae and is got tracheae and be detachable the connection between the gas flange with getting.This structure makes that getting tracheae is connected with adsorption tower closely, and when mounted, the hot weld slag can not cause damage to the mesh shade assembly, when damaging appears in the mesh cover, changes very convenient yet.
As preferably, the port of described mesh shade assembly is provided with an annular projection, and this annular projection is suitable with an annular groove of getting on the tracheae.This structure when mounted, with the mesh shade assembly earlier with get tracheae and link to each other, again with the mesh cover with get tracheae and extend into simultaneously in the adsorption tower, will get the completion of tracheae and adsorption tower again and fix.
As preferably; Described mesh shade assembly comprises a cross four-way connection; Each interface of four ends of this cross four-way connection links to each other with a cylindricality mesh cover respectively; The not end opening of one of them mesh cover, this opening are provided with an annular projection, and this annular projection is suitable with an annular groove of getting on the tracheae.This structure is applicable to large-scale adsorption tower, during installation, gets tracheae and fixedly gets on the gas flange, and cylindricality mesh cover is installed on the cross four-way connection, and installation personnel proceeds in the adsorption tower, is installed in and gets on the tracheae.
As preferably, each interface of four ends of described cross four-way connection links to each other with described cylindricality mesh cover through little flange respectively.This assembling all is detachable, when damaging appears in cylindricality mesh cover therein, all can change, reaching the purpose of practicing thrift maintenance cost, and install, processing is also more convenient.
As preferably, the length of described mesh shade assembly is the 7/10-9/10 of adsorption tower internal diameter.This structure makes gets the gas process evenly, fast, little to the influence of adsorption tower internal gas flow.
As preferably, described mesh shade assembly is horizontally disposed with, two relative cylindricality mesh covers not end distance from being the 7/10-9/10 of adsorption tower internal diameter.This structure makes gets the gas process evenly, fast, little to the influence of adsorption tower internal gas flow.
The beneficial effect that brings of the utility model is, solved existing in prior technology and occurred easily leaking, and the technical problem that can't change has realized that a kind of sealing is reliable, changed collector in the middle part of the device of the transformation adsorbed gas easily adsorption tower.
