Problems solved by technology

[0002] In recent years, the treatment of boiler water and industrial circulating water (circulating cooling water in nitrogen fertilizer plants, oxygen production workshops and pharmaceutical factories, etc.) is mostly phosphate-based formulations, usually using orthophosphate, pyrophosphate, sodium tripolyphosphate , sodium hexametaphosphate, etc. The above-mentioned water treatment agents have good corrosion and scale inhibition effects and are widely used, but they have the following disadvantages in use: ①PO 4 3- There is no threshold effect on scale inhibition, so it has no inhibitory effect on scale and can only generate Ca 10 (OH) 2 (PO 4 ) 6 Water slag is formed according to stoichiometry, the amount of sewage is large, and the boiler water cannot be operated at a high concentration multiple
⑤ Phosphate will also be entrained into the steam and deposited on the blades of the steam compressor, affecting the long-term safe and stable operation of the steam compressor
[0004] Therefore, at present, the raw materials of boiler water conditioners are mainly chemical and chemical products. The preparation process of boiler water conditioners mainly adopts the process of batching and mixing. At present, no other preparation process has been found, especially the preparation of boiler water conditioners by microbial fermentation method has not been found. agent reports

Abstract

The invention discloses a method for preparing a boiler water regulator through a microbial fermentation method. The boiler water regulator is composed of the following raw materials in parts by mass:5-10 parts of sodium tannate, 3-5 parts of glucose, 5-12 parts of alga, 3 parts of glycol derivatives, 3-5 parts of cotton straws, 2 parts of starch, 1 part of a deoxidant and the balance of water. According to the boiler water regulator prepared by utilizing the microbial fermentation method, the requirements of the boiler water regulator on raw materials are reduced, and effects of the boiler water regulator are obviously improved by utilizing flocculation of heating modification of micro-proteins; and the regulator does not contain phosphate and hydrazine compounds or any other toxic substance, boiler oxygen corrosion and condensate water corrosion can be controlled, the boiler water concentration multiple can be greatly improved, the boiler blow-down rate is reduced, water resources and heat energy are saved, and aims of energy conservation and emission reduction are achieved.
