Application of scale inhibitor containing sodium gluconate to salt-draining closed conduit

Abstract

The invention relates to a scale inhibitor containing sodium gluconate. The scale inhibitor comprises the following components by weight parts: 15-19 parts of amino trimethylene phosphonic acid, 10-14 parts of polyaspartic acid, 8-12 parts of hexapotassium salt, 6-10 parts of zinc sulfate, 6-10 parts of tartaric acid, 1-5 parts of aluminum polychlorid, 2-6 parts of dodecyl dimethyl benzyl ammonium chloride, 1-5 parts of butyl hydroxy anisd, 1-5 parts of lauric acid, 2-6 parts of lauryl sodium sulfate, 1-5 parts of sodium gluconate, 0.2-0.6 part of bladder-wrack extracts, 0.2-0.6 part of throatroot root extractives and 52-56 parts of deionized water. The scale inhibitor provided by the invention has excellent inhibiting function for the algae propagated in the salt-draining closed conduit, has excellent scale inhibition effect for the inorganic salt sediment in the salt-draining closed conduit and can prolong the service life of the salt-draining closed conduit for 10-12 years.

Description

technical field [0001] The invention relates to a scale inhibitor containing sodium gluconate, specifically, the application of a scale inhibitor containing sodium gluconate in a salt discharge underground pipe, belonging to the technical field of salt discharge in a saline-alkali underground pipe. 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 sa...

AI Technical Summary

Problems solved by technology

[0005] (1) It has no inhibitory effect on the algae growing in the salt-discharging dark pipe, which reduces the service life of the dark pipe;

[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) The scale inhibition efficiency is low, the dosage is large, and when it is discharged to the external environment, it cannot be biodegraded, which is likely to cause environmental pollution and increase the cost of subsequent treatment;

[0008] (4) It is easy to cause corrosion of the pipe wall of the salt drainage pipe
