Description
Technical Field
The invention relates to the technical field of electric power environmental protection, in particular to a coating for preventing a smoke cooler of an ultra-low emission unit from being blocked, and a preparation method and application thereof.
Background
The ultra-low emission modification is an atmospheric pollutant remediation project which is greatly promoted in the coal-fired power generation industry in recent years. At present, domestic large coal-fired power stations have basically completed ultra-low emission reconstruction, the total emission of main atmospheric pollutants is obviously reduced, but the reconstruction also brings negative effects to units. Wherein, the blocking of low temperature heat transfer equipment (especially smoke cooler) is the ubiquitous problem of minimum emission unit, has constituted serious danger to boiler efficiency and unit safe operation. The reason is that in the ultralow emission modification process, in order to obtain higher denitration efficiency, the use amount of the SCR catalyst is increased, the ammonia injection amount is increased, and the concentration of escaping ammonia and sulfur trioxide in the flue gas is increased. Ammonium Bisulfate (ABS) generated by the reaction of ammonia and sulfur trioxide with water is also increased, while liquid ABS has viscosity and is easily deposited on the heat exchange surface and adsorbs fly ash, causing heat exchanger blockage. Therefore, the anti-contamination performance of the heat exchange surface is improved, the adhesion of ABS on the heat exchange surface is reduced, and the method is an important technical approach for solving the problem of blockage of low-temperature heat exchange equipment of a power plant.
The self-cleaning coating can improve the anti-contamination performance of the heat exchange surface. For example, chinese patents CN 107401950A, CN106010122A, CN105199497A, CN104987032A, CN106752132A and CN102390936B disclose a plurality of self-cleaning coatings, which are sprayed on various heat exchange surfaces to endow the heat exchange surfaces with better anti-contamination performance. Because the ultra-low emission unit has bad operation condition, the coating is required to have anti-scouring (the smoke velocity is 10m/s, the dust content is 30g/m3Left and right), high temperature resistance (long-term operation temperature is 200-150 ℃), sulfuric acid corrosion resistance, strong heat conduction and adhesion, simple coating and the like,the coating in the prior art has poor high temperature resistance, acid corrosion resistance or adhesion performance with a matrix, and is not suitable for smoke coolers in an ultra-low emission unit. Therefore, it is necessary and important to develop new self-cleaning coatings.

Compared with the prior art, the invention has the following beneficial technical effects:
(1) the thermoplastic resin coating has high temperature resistance, strong hydrophobicity and excellent self-cleaning performance, but because the film forming property is poor, a large number of micropores exist after the coating is solidified, acid liquid can permeate into a coating/matrix interface through the micropores to corrode a matrix (heat exchange surface), and meanwhile, the stripping of the coating from the surface of the matrix is accelerated. The organic silicon coating has good film forming property, high temperature resistance and strong adhesive force, but the anti-contamination performance needs to be improved. Therefore, when the thermoplastic resin coating and the organic silicon coating are used independently, the use requirements of the smoke cooler of the ultra-low emission unit cannot be met.
