Problems solved by technology

[0002] The boiler is an industrial tool that cannot be separated in daily life, and it is easy to produce scale or other sediments. These water channels are usually formed by the precipitation of carbonates and hydroxides. In addition, the current water body is seriously polluted and has many impurities. There may even be reclaimed water, etc. Therefore, it is difficult to clean it with ordinary water, and the descaling agents bought on the market are expensive and unsatisfactory in descaling effect, and there are even many descaling agents. Descaling agents are highly corrosive, causing great harm to human bodies and boilers. There is a great demand for descaling agents in industry, and they are widely used. New limescale will build up soon

Embodiment 1

[0020] For a boiler with a dirt thickness of about 2.8mm and a capacity of 1 ton, use the following boiler descaling method, including the following steps:

[0021] 1) Inject 800kg of water into the boiler to be descaled;

[0022] 2) In a sealed state, stir the solution in the descaling boiler, and at the same time, inject 48.0% acetic acid solution into the descaling boiler until it is full;

[0023] 3) Heat the boiler to be descaled, stop heating when heated to 60~70°C, continue stirring for 90 minutes, drain the solution in the boiler to be descaled, and wash it with clean water;

[0024] 4) Use starch to configure an anti-scaling solution with a volume of 6.5-15.0% of the volume of the descaling container and a concentration of 0.05-0.19%, inject the anti-scaling solution into the descaling boiler, heat until 60.0-75.0°C, and Stir for 10 minutes;

[0025] 5) Clean the descaled boiler with clean water.

[0026] It has been tested that more than 97% of the boiler scale ha...

Abstract

The invention relates to a boiler descaling method, comprising the steps of preparing a vinegar solution with a certain concentration and volume, descaling a boiler by using the prepared vinegar solution and simultaneously performing the operations of stirring, heating and the like, and the like; and preparing a scale prevention solution with a certain concentration and volume by using starch after descaling the boiler, wherein the scale prevention solution is used to reduce the regeneration speed of the scale in the boiler. The method disclosed by the invention has the advantages that raw materials are wide in source range and have low price, and the effects of descaling, reducing the generation speed of the scale, and the like can be simultaneously achieved, and no harms are brought to the human body.

Description

technical field [0001] The invention relates to a method for descaling, in particular to a method for descaling a boiler. Background technique [0002] The boiler is an industrial tool that cannot be separated in daily life, and it is easy to produce scale or other sediments. These water channels are usually formed by the precipitation of carbonates and hydroxides. In addition, the current water body is seriously polluted and has many impurities. There may even be reclaimed water, etc. Therefore, it is difficult to clean it with ordinary water, and the descaling agents bought on the market are expensive and unsatisfactory in descaling effect, and there are even many descaling agents. Descaling agents are highly corrosive, causing great harm to human bodies and boilers. There is a great demand for descaling agents in industry, and they are widely used. Soon new limescale will form. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, ...
