Description

Technology Field

[0001] The present invention belongs to the field of column interior materials and relates to the structure and mounting method of a through-flow type profile column plate. Background Technology

[0002] Through-flow column plates are gas-liquid counterflow column plates without downcomers, where gas contacts from bottom to top and liquid contacts from top to bottom through the column plate gaps. Here, through-flow corner profile column plates have a simple structure, excellent anti-clogging effect, high processing capacity, and low cost, and are widely used in unit operations such as rectification and absorption. The gas-liquid contact channels of through-flow multilayer stepped corner profile column plates are determined by the horizontal and vertical distances between vertically adjacent corner profiles and the fixed angles of the corner profiles. Therefore, the corner profiles must be evenly arranged in the horizontal and vertical directions, and the mounting angles of each corner profile must match; otherwise, it may affect the separation effect of the column plate.

[0003] Currently, most through-flow type corner profile column plates use welding to fix the corner profiles onto transverse beams or side plates. For single-layer corner profile column plates, this fixing method barely meets requirements, and once two-layer or multi-layer corner profiles are involved, it becomes difficult to guarantee the size accuracy of the column plate slit width and the mounting angle of the corner profile, affecting the efficiency of the column plate.

[0004] In the case of extra-large column plates, corner profile column plate subblocks are manufactured first, and then multiple column plate subblocks are used to assemble the entire column plate by welding or adding working plates and connecting them with bolts. In order to compact each column plate subblock, the installer must press each column plate subblock with a cover plate or support plate and then weld or connect them with bolts. Since mounting requires the cooperation of multiple people, it is very inconvenient and difficult to ensure mounting flatness; extra-large column plates have stricter requirements for mounting flatness, and problems such as low strength and easy deformation after size expansion appear, resulting in a short lifespan for the column plate. The problem to be solved

[0005] In light of this, the present invention aims to provide a structure and mounting method for a through-flow profile column plate to solve the problem that exists when assembling existing column plate subblocks into the entire column plate. means of solving the problem

[0006] To achieve the above objective, the present invention provides the following technical solution.

[0007] The structure of the through-flow profile column plate includes a rectangular column plate subblock and an arc-shaped column plate subblock, and a plurality of rectangular column plate subblocks and arc-shaped column plate subblocks are fixedly connected to the upper side of the support beam and horizontally assembled in the inner area of ​​the support ring to form a column plate;

[0008] A column plate subblock comprises a side plate, a support plate, and a profile; a plurality of side plates are connected in a closed loop; a plurality of support plates are fixedly connected to the side plates and distributed parallel to each other within the inner area of ​​the side plates; a profile is installed within the inner area of ​​the side plates; in the vertical direction, multi-layer profiles are distributed vertically in an offset manner parallel to each other and arranged in a stepped manner; in the horizontal direction, a plurality of profiles are evenly distributed parallel to each layer; holes matching the profiles are opened on the support plates and side plates; the profile passes through the holes on the support plates and its ends are inserted into the holes on the side plates; and the profiles and the holes on the side plates are fixedly connected at the contact points;

[0009] The corners of adjacent column plate subblocks are enclosed to form a single complete buckle groove, and the buckle groove is buckled by a pressing plate installed on the upper side. A connecting hole corresponding to the buckle groove is installed on the pressing plate, and a positioning hole corresponding to the buckle groove is installed on the support beam and support ring. Fixing bolts are inserted into the connecting hole of the pressing plate, the buckle groove, and the positioning hole of the support beam, respectively, and into the connecting hole of the pressing plate, the buckle groove, and the positioning hole of the support ring, and are fastened by combining with fixing nuts.

[0010] Additionally, a fixing nut bracket is fixedly connected to the lower side of the support beam and support ring, corresponding to a positioning hole, and a fixing nut is installed on the fixing nut bracket, thereby stopping rotation and limiting position with respect to the fixing nut.

[0011] Additionally, the fixing nut bracket is U-shaped, and the opening is buckled onto a support beam or support ring; the fixing nut is positioned in the internal space of the fixing nut bracket, and a through hole larger than the internal hole of the fixing nut is correspondingly installed on the fixing nut bracket so that a fixing bolt passes through; the size of the internal space of the fixing nut bracket is slightly larger than the fixing nut so as to prevent rotation of the fixing nut.

[0012] Additionally, the multilayer profile is formed from one or more combinations of corner profiles, triangular profiles, square profiles, and circular profiles.

[0013] Additionally, the vertical spacing between the profiles of two vertically adjacent layers is the same, and the centerlines of the profiles of odd layers and odd layers, and even layers and even layers are aligned in the vertical direction.

[0014] Additionally, the horizontal gap between two adjacent profiles in the top layer of the multilayer profile is larger than the horizontal gap between two adjacent profiles in other layers, and the horizontal gap between two adjacent profiles in the top layer is a droplet removal structure.

[0015] Additionally, the size of the top profile is 0.5 to 0.8 times that of the profiles of other floors.

[0016] The mounting method of the above-described through-flow profile column plate is,

[0017] Mounting of a column plate subblock: a step of passing each profile through a hole on a support plate, inserting both ends of the profile into holes on a side plate, and fixing the contact points of the profile, the support plate, and the holes on the side plate by spot welding to form a column plate subblock; and

[0018] Mounting of column plates: The method is characterized by including the step of assembling and arranging each column plate sub-block on a support ring and a support beam, buckling together the buckle grooves formed by adjacent column plate sub-blocks using a pressing plate on the upper side of the column plate sub-block, then sequentially passing a fixing bolt through the connection hole of the pressing plate, the buckle groove and the positioning hole on the support beam, and the connection hole of the pressing plate, the buckle groove and the positioning hole on the support ring, respectively, and fastening the column plate sub-blocks by combining them with a corresponding fixing nut to complete the mounting of the column plates.

[0019] Additionally, when a fixing nut bracket is pre-welded to the lower side of the support beam and support ring to correspond to positioning holes, a fixing nut is placed thereon, and the column plate subblock is secured by a fixing bolt, the fixing nut bracket restricts the position of the fixing nut placed thereon to prevent follow rotation. Effects of the invention

[0020] The beneficial effects of the present invention are as follows.

[0021] (1) By installing holes on the support plate and side plate, the planar displacement and three-dimensional displacement of the profile are limited, making the positioning of the multilayer profile more accurate and easier to mount. At the same time, the profiles are evenly arranged in the horizontal and vertical directions, and the mounting angles of each profile are aligned, thereby ensuring uniformity of gas-liquid contact and improving column plate efficiency.

[0022] (2) By setting the horizontal gap between two adjacent profiles in the top layer to be larger than the horizontal gap between two adjacent profiles in other layers, the horizontal gap between profiles in other layers ensures sufficient gas-liquid contact, the horizontal gap between profiles in the top layer increases, the gas velocity decreases, and impurities and liquid droplets flow to the lower layer under the gravitational action of the gas, thereby removing the droplets; there is no need to add a demister, and the column plates in each layer have a droplet removal function, so the droplet removal efficiency is greatly improved, the gas-liquid separation space is reduced, the required column plate spacing is reduced, the height of the entire device is reduced, and the cost of the device is reduced.

[0023] (3) By setting up a press plate with a connection hole to connect multiple column plate subblocks and fixing them on a support beam or support ring through a fixing nut and a fixing bolt, the press plate not only performs a connecting function but also limits the displacement of the column plate, making it more convenient to mount and detach the column plate.

[0024] (4) The support plate and side plate not only serve to fix the profile, but can also be used as a supporting beam for the column plate itself, thereby solving the problem of supporting and strengthening large column plates.

[0025] (5) By installing a fixing nut bracket and pre-welding it to the support beam and support ring, not only can the follow rotation of the fixing nut be effectively prevented, but the quick mounting and detachment of the fixing nut can also be conveniently implemented, thereby ensuring the performance of the fixing nut and guaranteeing the quality of the assembly.
