Application of scale inhibitor containing itaconic acid in hidden salt elimination tube

Abstract

The invention relates to a scale inhibitor containing itaconic acid. The scale inhibitor comprises the following components in parts by weight: 32-36 parts of sodium ethylenediamine tetramethylene phosphonate, 21-25 parts of tetrasodium aminotrimethylene phosphonate , 11-15 parts of sodium polyacrylate, 10-14 parts of tartaric acid, 10-14 parts of itaconic acid, 6-10 parts of methylisothiazolinone, 6-10 parts of 2,2-dibromo-3-nitrilopropionamide 10 parts, 5-9 parts of tolyltriazole, 5-9 parts of sodium sulfite, 1-9 parts of sodium lauryl sulfate, 2-6 parts of methyl amyl alcohol, 1-5 parts of licorice extract, moon peach leaf 1-5 parts of extract, 52-56 parts of water, the antiscalant of the present invention is stable in nature, has a long storage period, and has good scale inhibition effect on the precipitation of inorganic salts in the salt-discharging dark pipe, and has no effect on the salt-discharging dark pipe. Corrosion and scale inhibition efficiency is high, the dosage is small, when it is discharged to the external environment, it will not cause environmental pollution, and there is no need for subsequent treatment costs.

Description

technical field [0001] The invention relates to an itaconic acid-containing scale inhibitor, in particular to the application of an itaconic acid-containing scale inhibitor in a salt discharge underground pipe, and belongs to the technical field of saline-alkali underground pipe salt discharge. Background technique [0002] Underground pipe salt drainage technology is to lay a pipe with pores at a certain depth underground (above or below the groundwater level), and the water that flows into the pipe after irrigation or rainfall, or directly flows into the groundwater in the pipe, and is discharged through the pipe land, take away the salt, and play the purpose of improving saline-alkali land. Underground pipe salt drainage is relative to open ditch salt drainage. Open ditch salt drainage is to dig ditches with a certain depth at a certain distance in the field to discharge soil salt and improve saline-alkali land. The effect of underground pipe salt drainage technology on ...

AI Technical Summary

Problems solved by technology

[0005] (1) Antiscalants are unstable in nature, short in storage time and poor in dispersibility;

[0006] (2) The scale inhibition effect on insoluble inorganic salts in saline-alkali water is not obvious, and it is easy to cause blockage of the salt discharge pipe;

[0007] (3) It is easy to cause corrosion of the pipe wall of the salt discharge underground pipe;

[0008] (4) The scale inhibition efficiency is low, and the dosage is large. When it is discharged to the external environment, it is easy to cause environmental pollution and increase the cost of subsequent treatment.
