Abstract

The invention discloses a scale inhibition method for a boiler, and relates to the technical field of industrial boilers, and the scale inhibition method comprises the following steps: extracting a small amount of boiler water at a boiler dosing port in advance, collecting the index information of the boiler water, and obtaining the concentration of an added scale inhibitor; a scale inhibitor is added with the outlet end of a deoxidizing opening of the boiler as a dosing opening, and the scale inhibitor mainly comprises pure water, sodium alginate, organic phosphate, trisodium phosphate, sodium hydroxide, a deoxidant and a metal corrosion inhibitor; the action condition of the scale inhibitor is monitored, and the concentration of the scale inhibitor is adjusted. The corrosion and scale inhibitor has excellent corrosion and scale inhibition performance, can form a layer of protective film on the metal surface, greatly reduces the corrosion rate, and has the advantages of simple operation, thorough descaling, convenient cleaning, safety to equipment, safety and environmental protection.

Description

technical field [0001] The invention relates to the technical field of industrial boilers, in particular to a scale inhibition method for boilers. Background technique [0002] The boiler system will inevitably produce scale and rust in the long-term use process, which will reduce the thermal efficiency by an order of magnitude. The evaporation of water gradually increases the salt content in the boiler system, and the decomposition and dissipation of carbon dioxide in the water increases the tendency of calcium carbonate in the water to scale and precipitate on the heat transfer surface. After the scale and rust are produced, not only a lot of energy is wasted, but also the service life of the whole system is greatly reduced due to the rusting of pipes and equipment, resulting in a lot of unnecessary losses. In addition, the tube wall in some places of the boiler is very thin and thin, and the thickness of the dirt should be strictly controlled. [0003] Therefore, it is ...
