Environment-friendly circulating water softening agent with scale inhibiting effect

Abstract

The invention discloses an environment-friendly circulating water softening agent with a scale inhibiting effect. The softening agent is prepared from the following components: sodium tripolyphosphate, carbonate, sodium hydroxide, activated carbon, deionized water, polyvinyl chloride, a flocculant and a deoxidizer. The softening agent is prepared through the following steps: firstly, dissolving sodium tripolyphosphate, polyvinyl chloride and active carbon which are weighed in percentage by weight of raw materials in deionized water, and performing stirring uniformly; then, adding carbonate, sodium hydroxide, the flocculant and the deoxidizer, performing stirring uniformly, cooling a mixture to room temperature, and finally, performing drying and molding. The softening agent has the effectsof removing scale, inhibiting scale and rust and partially removing calcium hardness on different kinds of industrial water, coal mines, water supply pipes and other equipment, the scaling tendency of water is eliminated, the content of calcium ions in the circulating water is reduced, and the purpose of partial softening is achieved; the softening agent is safe, convenient to use and low in environmental pollution, and secondary pollution to the environment due to the adopted raw materials is prevented.

Description

technical field [0001] The invention relates to the technical field of softened water, in particular to an environment-friendly softener for circulating water that suppresses scale. Background technique [0002] In the existing technology, after the industrial water is recycled, the metal iron ions, a large amount of calcium ions and magnesium ions in the water, dissolved solids and suspended solids increase accordingly, and pollutants in the air such as dust, sundries, soluble gases and Heater material leakage, etc., can enter the circulating water, causing corrosion and scaling of the equipment and pipes in the circulating water system, resulting in low heat transfer efficiency of the heat exchanger, reduced water flow, and even corroded and perforated equipment pipes. [0003] Among them, when the circulating water containing a large amount of calcium ions and magnesium ions passes through the pipeline, the scale will easily stick to the pipe wall for a long time, which w...

Problems solved by technology

[0002] In the existing technology, after the industrial water is recycled, the metal iron ions, a large amount of calcium ions and magnesium ions in the water, dissolved solids and suspended solids increase accordingly, and pollutants in the air such as dust, sundries, soluble gases and Heater material leakage, etc., can enter the circulating water, causing corrosion and scaling of the equipment and pipes in the circulating water system, resulting in low heat transfer efficiency of the heat exchanger, reduced water flow, and even corroded and perforated equipment pipes

[0003] Among them, when the circulating water containing a large amount of calcium ions and magnesium ions passes through the pipeline, the scale will easily stick to the pipe wall for a long time, which will easily block the pipeline, reduce the flow rate, damage the equipment, and bring losses to industrial production.
