Description

Desulfurization pipeline processing technology
Technical Field
The invention relates to the technical field of desulfurization pipelines, in particular to a desulfurization pipeline processing technology.
Background
The desulfurization pipeline is a conveying pipeline applied to a desulfurization system, and the solution with acid and alkali substances conveyed in the desulfurization system must have the effects of corrosion resistance, wear resistance, temperature resistance and the like so as to ensure the normal operation of the desulfurization system. The common desulfurization pipelines comprise stainless steel, high-alloy composite steel plates, glass flakes and lining coatings which are applied to the market, but rubber-lined pipelines with more rubber linings are applied to the market as the desulfurization pipelines.
In the production process of the existing rubber-lined pipeline, a rubber-lined pipe made of rubber is directly penetrated through a desulfurization pipe by pulling force, so that the outer side wall of the rubber-lined pipe abuts against the inner side wall of the desulfurization pipe. Because the rubber lining tube and the desulfurization tube are in addiction matching, the rubber lining tube can be extruded and deformed under the extrusion of the desulfurization tube, so that the outer side wall of the rubber lining tube abuts against the inner side wall of the desulfurization tube after the rubber lining tube is installed. Because the rubber lining pipe and the desulfurization pipe are in addiction matching, when the rubber lining pipe passes through the desulfurization pipe, the rubber lining pipe and the desulfurization pipe are damaged by friction, so that the corrosion resistance and the wear resistance of the rubber lining pipe are influenced.
Simultaneously current desulfurization pipe makes the lateral wall of lining rubber tube support the inside wall of desulfurization pipe through the resilience force of lining rubber tube itself in the course of working, this requires than higher to the size machining precision of lining rubber tube, if the resilience force of lining rubber tube is less, then can not make the lateral wall of lining rubber tube support the inside wall of desulfurization pipe through the resilience force of lining rubber tube itself, make the lateral wall of lining rubber tube support and produce the gap between the inside wall of desulfurization pipe easily, thereby reduce the installation stability of lining rubber tube.
Disclosure of Invention

A clamping groove 23 is formed in one side of each clamping plate 22, and a clamping convex block 24 matched with the clamping groove 23 of the adjacent clamping plate 22 is arranged on the other side of each clamping plate 22; the side walls of the two adjacent clamping plates 22 close to one side of the pipeline body 1 are positioned on the same plane after the two adjacent clamping plates 22 are clamped and tightly abutted by the clamping grooves 23 and the clamping convex blocks 24.
The working principle is as follows: the pipe body 1 with the rubber lining pipe 3 mounted thereon is first hung to the pipe support rod 19 by a crane. Then, the driving cylinder 21 is driven to make the clamping plates 22 tightly contact with the two side walls of the pipeline body 1. The hook 15, without the press body 14 attached, is then threaded through the pipe body 1 with the pull cord 13. After the hook 15 penetrates through the pipeline body 1, the hook 15 is connected with the extrusion body 14, and the extrusion body 14 is pushed into the rubber lining pipe 3 to be abutted against the rubber lining pipe 3. Then the winch is driven, the winch drives the extrusion body 14 to penetrate through and extrude the rubber lining pipe 3 through the pull rope 13, and therefore the rubber lining pipe 3 is tightly abutted to the inner side wall of the pipeline body 1.
Examples 2 to 5 differ from example 1 in that the lubricating oil comprises the following components in parts by mass:
Figure BDA0002223463500000111
examples 6 to 9 differ from example 1 in that the adhesive comprises the following components in parts by mass:
Figure BDA0002223463500000112
comparative example
The difference between the comparative example 1 and the example 1 is that the lubricating oil is a common lubricating oil, and the manufacturers are as follows: jiangsu Yingji lubrication science and technology, Inc.
Detection method
The peeled pipes obtained in example 1 and comparative document 1 were used under high temperature and high pressure, and the environmental factors used were the same.
The peeling-off pipe used in reference 1 is detached from the adhesion between the rubber-lined pipe and the pipe body in 6 to 12 months during use.
The peel-off tube used in example 1 was released from the bond between the hose lining and the tube body during 15 to 18 months of use.
Therefore, the bonding strength between the rubber lining pipe and the pipeline body by adopting the matching use of the lubricating oil and the adhesive is greater than the bonding strength between the rubber lining pipe and the pipeline body by the existing lubricating oil and adhesive.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
