Application of antisludging agent containing citric acid in salt elimination closed conduit

Abstract

The invention relates to an antisludging agent containing citric acid. The antisludging agent is prepared from, by weight, 26-30 parts of 2-phosphonic acid butane-1,2,4-tricarboxylic acid, 15-19 parts of diethylenetriamine pentasodium bistriaminopenta, 7-11 parts of polyaspartic acid, 6-10 parts of citric acid, 4-8 parts of 1-bromo-3-chloro-5,5-dimethyl hydantoin, 4-8 parts of tertiary butyl hydroquinone, 3-7 parts of sodium glycocholate, 3-7 parts of lauryl sodium sulfate, 2-6 parts of tertiary butylhydroquinone, 0.5-0.9 part of a Kombuchka extracting solution, 0.4-0.8 part of a cactus extracting solution and 54-58 parts of deionized water. The antisludging agent is stable in character and long in storage life, has the good scale inhibition effect on inorganic salt sedimentations in a salt elimination closed conduit, and is free of corrosion of the salt elimination closed conduit.

Description

technical field [0001] The invention relates to a citric acid-containing scale inhibitor, in particular to the application of a citric 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 will flow into the pipe after irrigation or rainfall, or directly flow into the groundwater in the pipe, and discharge the land through the pipe , take away the salt, and play the purpose of improving saline-alkali land. The effect of underground pipe salt drainage technology on improving saline-alkali land has been proved. Underground pipe salt drainage follows the water and salt migration law of "salt comes with water, salt goes with water", and the water that has fully dissolved the soil salt and inf...

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.
