Embodiment 1

[0011] Example 1: Put 60 parts of distilled water into the reaction vessel, add 5 parts of ethylenediaminetetraacetic acid, 5 parts of citric acid, 3 parts of sulfamic acid, and 2 parts of benzotriazole into the reaction vessel, and stir for 2 Hours, the mixture is fully dissolved to obtain the finished product.

[0012] According to the use test, it can effectively solve the corrosion, scaling and slime generation of circulating water system pipes and heat exchangers, prolong the service life of equipment, improve heat exchange effect, and meet the requirements of environmental protection.

Embodiment 2

[0013] Example 2: Put 70 parts of distilled water into the reaction vessel, add 8 parts of ethylenediaminetetraacetic acid, 10 parts of citric acid, 6 parts of sulfamic acid, and 3 parts of benzotriazole into the reaction vessel, and stir for 2 Hours, the mixture is fully dissolved to obtain the finished product.

[0014] According to the use test, it can effectively solve the corrosion, scaling and slime generation of circulating water system pipes and heat exchangers, prolong the service life of equipment, improve heat exchange effect, and meet the requirements of environmental protection.

Embodiment 3

[0015] Example 3: Put 80 parts of distilled water into the reaction vessel, add 10 parts of ethylenediaminetetraacetic acid, 15 parts of citric acid, 10 parts of sulfamic acid, and 5 parts of benzotriazole into the reaction vessel, and stir for 2 Hours, the mixture is fully dissolved to obtain the finished product.

[0016] According to the use test, it can effectively solve the corrosion, scaling and slime generation of circulating water system pipes and heat exchangers, prolong the service life of equipment, improve heat exchange effect, and meet the requirements of environmental protection.

Abstract

The invention discloses an organic acid cleaning agent and a manufacture method thereof. The cleaning agent comprises citric acid 5-15 parts, sulfuric acid 3-10 parts, edetic acid 5-10 parts, H-Benzotriazole 2-5 parts and distilled water 60-80 parts according to parts by weight. The organic acid cleaning agent can effectively solve the problem of generation of corrosion, scaling and slime of circulation water system pipelines and heat exchangers, prolong service life of equipment, improve heat exchange efficiency and achieve the requirement for environment protection.

Description

technical field [0001] The invention relates to the technical field of water treatment agents, in particular to an organic acid cleaning agent for industrial circulating water and a manufacturing method thereof. Background technique [0002] At present, in our country's circulating water system, in the usual maintenance, there are generally many types of descaling agents, corrosion inhibitors and bactericidal algicides. If they are used properly, they will have a good effect. However, any chemical agent has different degrees of corrosion and sedimentation on equipment and pipelines. In the case of complex water quality, it is inevitable to deposit scale, breed bacteria and algae, and precipitate sludge after long-term operation, resulting in a decrease in thermal conductivity. Due to the increase of corrosion rate after fouling, it directly affects the service life of equipment and piping system. After improper use and scaling of equipment and piping systems, most of them s...
