Description
Technical Field
The utility model relates to a connection structure of different anticorrosive material belongs to heavy anticorrosive technical field for trade chimneys and flues such as thermal power factory, chemical industry, metallurgy, overlap joint between different anticorrosive material is handled.
Background
At present, in the domestic thermal power plant, chemical industry, metallurgy and other industries, corrosive gas and liquid are contacted, and a related chimney and a related flue are easily corroded and damaged. Therefore, the surface of the chimney and the flue substrate is generally subjected to anti-corrosion treatment, the chimney and the flue substrate are subjected to anti-corrosion treatment by adopting different anti-corrosion materials, but when the connection sequence of the connection interface of the two different anti-corrosion materials is incorrect, the anti-corrosion failure of the connection interface is easily caused, acidic liquid and gas penetrate through the connection joint to corrode the chimney and the flue, equipment failure is caused, and economic loss is caused.
Disclosure of Invention
The utility model discloses the problem that will solve: for the interfaces of different anticorrosive materials, a correct, effective anticorrosive structure is selected, in particular to a brick glue anticorrosive system and a coating scale anticorrosive system for the block materials in the chimney and the flue.
In order to solve the problem, the technical scheme of the utility model a connection structure at different anticorrosive material interfaces is provided, anticorrosive material is chimney/flue substrate and block material brick, a serial communication port, chimney/flue substrate is equipped with scale corrosion protection system for one side of block material brick, and block material brick surface covers has L type glass steel angle steel, and one side of L type glass steel angle steel is passed through self tapping screw and is connected fixedly with scale corrosion protection system, and packs between block material brick and the chimney/flue substrate and have the adhesive.
The technical scheme of the anti-corrosion structure provides a lapping method for different anti-corrosion materials during lapping, solves the quality problem of lapping corrosion resistance, can treat interface cold and hot expansion, resists acid liquid permeation, resists flue gas scouring of a stop surface, and adapts to complex environment in a chimney.
Compared with the prior art, the utility model has the advantages of:
(1) the cold and hot expansion performance is increased: the flue of the flue gas outlet of the absorption tower generally adopts a coating scale anti-corrosion system, a block material type brick glue anti-corrosion system is adopted when the flue gas outlet is connected with a chimney, the coating scale anti-corrosion layer is laminated and connected by adopting block material type brick glue anti-corrosion layers, the expansion caused by temperature change between different interfaces can be buffered, and the prior art is directly connected in a butt joint way;
(2) the seepage-proofing property is high: by using the novel lapping anti-corrosion process, acid liquid can not enter the base material through the connecting seam to corrode the base material;
(3) the block brick glue system cut-off surface adopts L type glass steel material cut-off strip, can resist the flue gas and erode;
(4) good temperature resistance and corrosion resistance: the chimney can adapt to cold and hot changes and strong corrosive complex environments in the chimney for a long time, and does not corrode or leak;
(5) the construction is easy: the preparation is convenient, the layered construction is realized, the process is simple and convenient, and the construction quality problem is not needed to be worried about.
