Spot proof and removing agent for middle and low pressure boiler

Abstract

The invention discloses an anti-descaling powder agent for medium low pressure boiler, which comprises the following steps: compositing with sodium carbonate and humic acid sodium; allocating 45-85 wt sodium carbonate and 15-25 wt humic acid; getting the product. This invention possesses merits as follow: collecting scale prevention and conservation as one body; forming a smooth protective film in the boiler; inhibiting corrosion of oxyhydrogen molecule; setting antiscaling ratio at 90% without toxic and pollution.

Description

technical field [0001] The invention relates to an anti-scaling and descaling powder for medium and low pressure boilers. Background technique [0002] At present, a large number of boilers are used in industry and civil use, among which medium and low pressure boilers account for 2 / 3, and high pressure boilers account for 1 / 3. Scaling is the most serious damage to boilers, especially medium and low pressure boilers (including hot water boilers). After being scaled, the service life will be shortened, the heat transfer efficiency will be affected, and energy will be wasted. In order to prevent boiler scaling or descaling, traditional soda ash method, sodium ion exchange method, electronic anti-scaling instrument and other methods are mostly used. Each boiler is pickled at least once a year, and the anti-scaling effect of the above methods is not ideal. Contents of the invention [0003] The object of the present invention is to provide an anti-scaling and descaling powder...
