Description
Technical Field
The invention relates to an outer axial strip-shaped screen cylinder used for process equipment in the industries of petrochemical industry and the like.
Background
The bar-shaped screen (also called Johnson screen) is a general industrial product, and has the advantages of excellent strength and rigidity, uneasy blockage, uniform and large aperture ratio, and the like, so the bar-shaped screen is widely applied to process equipment such as filtration, gas-solid or gas-liquid distribution, gas-solid or gas-liquid separation, and the like in the industries such as metallurgy, oil refining, chemical industry, medicine, food, water treatment, and the like. The axial strip-shaped screen cylinder is one of strip-shaped screens and consists of a circular ring-shaped supporting ring and screen bars. The cross section of each screen bar is in an isosceles triangle shape, and the length direction of each screen bar is parallel to the axial direction of the axial bar-shaped screen cylinder. The axial bar-shaped screen cylinder comprises an inner axial bar-shaped screen cylinder (called an inner net for short) and an outer axial bar-shaped screen cylinder (called an outer net for short). The annular support ring of the inner axial strip-shaped screen cylinder is positioned at the inner side, and the screen bars are positioned at the outer side; the annular supporting ring of the outer axial strip-shaped screen cylinder is positioned on the outer side, and the screen bars are positioned on the inner side.
The technological equipment of reactor, regenerator and others in the moving bed industrial equipment in petrochemical industry includes casing, inner axial bar screen cylinder, outer axial bar screen cylinder, manhole, reaction medium inlet, reaction product outlet, catalyst inlet, catalyst outlet, etc. The inner axial bar-shaped screen cylinder is positioned at the center of the shell, the outer axial bar-shaped screen cylinder is close to the inner wall of the shell, and an annular space for catalyst flowing is formed between the inner axial bar-shaped screen cylinder and the outer axial bar-shaped screen cylinder. The reaction medium radially passes through the catalyst bed layer in the annular space for reaction, and the reaction product generated after the reaction enters the cavity of the inner axial strip-shaped screen cylinder. Because the outer diameter of the inner axial strip-shaped screen cylinder is smaller, the inner diameter of the manhole can be designed to be larger than the outer diameter of the inner axial strip-shaped screen cylinder, so that the inner axial strip-shaped screen cylinder can freely go in and out of the manhole. While the outer diameter of the outer axial strip screen cylinder is only slightly smaller than the inner diameter of the casing. Due to the requirements of manhole structural design and strength design, the inner diameter of the manhole is smaller than the outer diameter of the outer axial strip-shaped screen cylinder.
The structure of a current outer axial bar screen cloth section of thick bamboo is an overall structure, has following shortcoming: (1) the outer diameter of the outer axial strip-shaped screen cylinder is larger than the inner diameter of the manhole, so that the outer axial strip-shaped screen cylinder cannot freely enter or exit the manhole. For installing the outer axial bar screen cylinder into the casing, there are two general solutions: firstly, in an equipment manufacturing plant, before the last girth weld of a shell is welded, an outer axial strip-shaped screen cylinder is arranged in the shell, and then the last girth weld of the shell is welded and heat treatment is carried out; but the heat treatment can cause damage to the outer axial bar screen cylinder. The above scheme can also cause transportation difficulties, and the outer axial strip-shaped screen mesh cylinder can be damaged in the transportation process, thereby influencing the stable operation of the process equipment. Secondly, at the project construction site, after the outer axial strip-shaped screen mesh cylinder is installed in the shell, the last girth weld of the shell is welded. According to the scheme, the heat treatment after the last circumferential weld of the shell is welded can also damage the outer axial bar-shaped screen cylinder, a series of problems such as field welding, field local heat treatment and the like are also involved, and higher requirements are provided for equipment manufacturing. If not implemented in place, the device may present a potential security risk. (2) Because outer axial bar screen cloth section of thick bamboo can't freely go in and out the manhole, in the process of the operation of process equipment later stage, when leading to outer axial bar screen cloth section of thick bamboo to damage because of misoperation or other reasons, it is very difficult to change the maintenance. (3) The size of the current petrochemical device is increased, the size (diameter, length and the like) of the outer axial bar-shaped screen cylinder is also increased, and the manufacture of the outer axial bar-shaped screen cylinder is difficult due to the overlarge size (for example, the outer diameter is more than 1.5 meters). For example, the corresponding machine equipment and manufacturing tools need to be updated, even the manufacturing factory needs to be modified and updated, and the like. This increases the manufacturing cost, resulting in an increase in engineering investment.

In order to solve the problems, the invention adopts the technical scheme that: an outer axial bar-shaped screen cylinder comprises single outer screens which are arranged in an upper-lower layered mode, and each single outer screen in each layer of single outer screen is arranged around the axial lead of the outer axial bar-shaped screen cylinder. The single outer screen comprises screen bars, and the length direction of the screen bars is parallel to the axial direction of the outer axial bar-shaped screen cylinder. And a top connecting plate and a bottom connecting plate are respectively arranged at the top and the bottom of the outer side of the screen bar in the single outer net, and connecting rod holes are formed in the top connecting plate and the bottom connecting plate. And support plates are arranged on the outer sides of the screen bars and between the top connecting plate and the bottom connecting plate. The outer axial bar-shaped screen mesh cylinder is provided with a connecting rod, and the connecting rod penetrates through the connecting rod hole from the top to the bottom of the outer axial bar-shaped screen mesh cylinder and from the upper part to the lower part of the outer axial bar-shaped screen mesh cylinder.

All top connecting plates, bottom connecting plates and supporting plates which are positioned at the same height position of the outer axial strip-shaped screen cylinder in each single outer screen are respectively spliced into a ring shape.
And in the single outer nets which are adjacent up and down, sealant or sealing gaskets are arranged between the adjacent bottom connecting plates and the top connecting plates.
The height of the monolithic outer net is generally 0.8-2 m. A single outer net is usually provided with 150-600 screen bars, and each top connecting plate and each bottom connecting plate are generally provided with 1-2 connecting rod holes.
The length of a chord opposite to the arc-shaped outer side edges of the top connecting plate and the bottom connecting plate is smaller than the inner diameter of a manhole on a process equipment shell.
The bottom connecting plate in the single outer net at the bottom layer of the outer axial strip-shaped screen cylinder is fixedly connected with the bottom of the connecting rod, and the top connecting plate in the single outer net at the top layer is fixedly connected with the top of the connecting rod.
The invention has the following beneficial effects: the external axial bar-shaped screen cylinder consists of a plurality of single external screens. The monolithic outer screen can be made smaller than the inner diameter of the manhole in the process equipment shell, so that the manhole can be freely accessed. When the invention is used, the single outer net and the connecting rod are firstly sent into the shell through the manhole, and then the outer axial strip-shaped screen cylinder is assembled in the shell. Therefore, the outer axial bar-shaped screen cylinder can be assembled after the last girth welding and heat treatment of the shell are completed and the shell is transported to a construction site, so that the outer axial bar-shaped screen cylinder is prevented from being damaged in the heat treatment and transportation processes, and welding and heat treatment on the site are avoided. When the monolithic outer net is damaged, the monolithic outer net can be detached and taken out of the shell through a manhole for maintenance, and a new monolithic outer net is reinstalled or installed after maintenance, so that the implementation difficulty is low. When the size of the outer axial bar-shaped screen cylinder is large, the screen cylinder can be assembled by more single outer screens with smaller sizes, machine equipment does not need to be updated, a manufacturing factory building is not needed to be reformed and updated, and the manufacturing cost and the engineering investment are reduced.
The invention can be used in various process devices such as reactors, regenerators, filters and the like in the industries of petrochemical industry, metallurgy and the like.
