Installation device for U-shaped grooved plates of strip-shaped bubble cap tray

Abstract

The invention provides an installation device for a U-shaped groove plate of a strip-shaped bubble cap tray, comprising a first end plug 1, the first end plug 1 is a rectangular block, and the first end plug 1 is welded on the side of the U-shaped groove plate outside, connect the adjacent U-groove plates. The invention can simplify the installation, disassembly and cleaning process of the U-shaped groove plate under the condition that the levelness and leakage of the tray are relatively high in the installation process of the water washing tower tray, so that the installation efficiency of the tray is greatly improved, and at the same time, the reduction of The workload of tray disassembly and assembly is reduced, and the leakage problem during tray installation is reduced.

Description

technical field [0001] The invention relates to a process for producing acetylene by partial oxidation of natural gas, in particular to an installation device for a U-shaped groove plate of a strip-shaped bubble-cap tray of an acetylene enrichment device in the process for producing acetylene by partial oxidation of natural gas. Background technique [0002] In the existing partial oxidation of natural gas to acetylene process, the strip-shaped bubble-cap tray of the advanced acetylene washing tower of the acetylene enrichment device, the main components are strip-shaped bubble-caps, U-shaped groove plates, end plugs, support beams, etc. During normal production, the entire The tray is filled with liquid to seal the gas and make the gas and liquid fully contact. It is required that the liquid in the upper tray can only flow from the downcomer of the tray to the next tray to ensure the washing effect. When disassembling the tray, 1148 bubble caps were gradually removed piece ...

AI Technical Summary

Problems solved by technology

When disassembling the tray, 1148 bubble caps were gradually removed piece by piece, 1400 end plugs were gradually removed piece by piece, 1218 "U" shaped groove plates were gradually removed piece by piece, and the tower was taken out for pickling. It is very large; during assembly, 1148 blister caps are gradually reassembled piece by piece, 2296 end plugs are gradually reassembled piece by piece, and 1218 "U" shaped groove plates are gradually reassembled piece by piece. A single-layer tray water test must be carried out for each layer of trays. If there is a large amount of water seepage, it will be judged that the installation of the tray of this layer is unqualified. During the maintenance, the water-filling test of the trays failed many times, and even a layer of trays was repeatedly disassembled and assembled. It took three days to install a layer of trays, which could not guarantee the maintenance period. It is particularly large. In order to catch up with the construction period, sometimes even 24 hours of operation is adopted, and the operation method of changing personnel without stopping; during the installation process, especially the installation of the "U" shaped groove plate, the The sealing of the side and bottom is the most difficult to ensure. The left, right and bottom of the end plug need to be sealed well to ensure that the tray does not leak. The bottom of the end plug is sealed by the bolts installed in the middle hole of the end plug, which is relatively easy to do. It is difficult to seal the left and right sides of the end plug. Round sealing strips are required on both sides of the end plug to seal. If the size of the sealing strip is too small, the end plug is easy to install, but the sealing effect is not good and it is easy to leak; if the size of the sealing strip is too large , the end plug is not easy to install, but the sealing effect is better. It is necessary to ensure that the bolt passes through the middle hole of the end plug, and to achieve a good seal. The construction is very difficult and the construction workload is heavy.
