Technical Field

[0001] This utility model relates to the field of anti-icing technology for resin conveying pipelines, and more specifically, to an anti-icing device for resin conveying pipelines. Background Technology

[0002] Resin in power plants is mainly used in water purification and ion exchange processes. The role of resin in power plants is to remove impurities and harmful substances from water through ion exchange, ensuring the purity of the water source. Specifically, resin can remove cations and anions from water, such as calcium carbonate, magnesium ions, ammonium, copper, and nickel, thereby improving water quality.

[0003] However, in extremely cold weather, when resin delivery pipelines freeze, it puts pressure on the resin pipelines and equipment, leading to equipment rupture or difficulty in resin flow, thus affecting production progress. For example, freezing of resin delivery pipelines can prevent the timely output and regeneration of failed resin from the high-speed mixed bed in the fine treatment process. The ammoniaation of failed resin can cause the water quality in the turbine to deteriorate, affecting the safe operation of the unit, causing unnecessary pipeline leaks, corrosion, salt accumulation, and affecting the economic operation of the turbine.

[0004] Therefore, there is an urgent need to develop a technical solution to address the problem of resin conveying pipelines freezing, thereby preventing the resin conveying pipelines from freezing and ensuring the normal and economical operation of the steam turbine. Summary of the Invention
