Reinforcing Method of Brick Lining in Strong Corrosive Environment

Abstract

The invention discloses a reinforcement method for a brick lining in a strongly corrosive environment, comprising the following steps: S1) pulling out the brick lining at the reinforcement point out of the cavity; excavating a grouting groove downward on the surface of the lining matrix, Bolt holes are opened downward at the center of the center of the bolt; S2) Put the lower end of the bolt into the bolt hole, inject the grout into the grout groove, and then insert the embedded part from the upper end of the bolt; S3) Put the embedded part on the flat plate The surface is attached to the lining board, and the outer periphery of the lining board is overlapped with the inner lining board of the brick lining; S4) Install a rubber ring in the U-shaped groove in the middle of the embedded part and fill it with soft cement, and press the first compression nut Put the rubber ring and soft cement down from the upper end of the bolt; S5) cover the reinforcement plate on the top surface of the cavity, and insert the second compression nut from the upper end of the bolt to compress the reinforcement plate downward. The method of the invention is simple, the engineering quantity is small, the cost is low, the construction period is short, the abrasion resistance and the sealing performance are good, and the pressure instability of the brick lining can be effectively avoided.

Description

technical field [0001] The invention relates to a method for reinforcing brick linings in the chemical industry, in particular to a method for strengthening brick linings in strong corrosion environments. Background technique [0002] At present, some chemical equipment usually lay a layer of brick lining on the surface of the lining substrate to play the role of abrasion resistance and corrosion resistance. However, when the medium in the equipment is in a strongly corrosive environment, the brick lining is in contact with the medium for a long time, and it is easy to expand when it is soaked in the medium and heated up. Problems such as collapse to the medium side will eventually lead to corrosion of the lining matrix of the equipment and affect the normal operation of the equipment. When the above problems occur, the traditional solution is usually to completely remove the brick lining and re-build it. On the one hand, it will bring the disadvantages of equipment shutdow...

Problems solved by technology

However, when the medium in the equipment is in a strongly corrosive environment, the brick lining is in contact with the medium for a long time, and it is easy to expand when it is soaked in the medium and heated up. Problems such as collapse to the medium side will eventually lead to corrosion of the lining matrix of the equipment, affecting the normal operation of the equipment

When the above problems occur, the traditional solution is usually to completely remove the brick lining and re-build it. On the one hand, it will bring the disadvantages of equipment shutdown, excessive maintenance, large maintenance costs and long construction period. On the other hand, re-build After brick lining, the problem of brick lining being unstable under pressure still exists, and after a period of use, there will still be hollowing, cracking and even collapse to the medium side.
