Open industrial circulating-cooling water concentrating ratio and drug concentration balance control method

Abstract

The invention provides a kind lf balance control way of open style industry recycling cooling water's weight concentration and pharmacy concentration .And weight concentration balance control way mainly controls the amount of water and salt of the industry recycling cooling water system ,according to the weight concentration N to control the add water and sewage water effectively to realize the balance control over the weight concentration of the industry recycling cooling water .And the pharmacy concentration balance control way is carried out on the basis of the weight concentration balance control way ,on the basis of weight concentration no change ,through adjusting and controlling the add water amount and dosing amount's proportion ,making the add dosage equal to the losing dosage in the same time of the system ,so realizing the pharmacy concentration keeping no change in the recycling water .The invention's advantages are saving water source ,keeping water quality stable ,etc.

Description

technical field [0001] The invention relates to a method for controlling open industrial circulating cooling water, in particular to a method for controlling the balance of the concentration ratio and chemical concentration of open industrial circulating cooling water. Background technique [0002] At present, the basic method of controlling the concentration multiple of open industrial circulating cooling water in my country is to regularly analyze the concentration of a certain substance in the circulating water, and then calculate the concentration multiple based on the concentration of a certain substance in the supplementary water. Then adjust the supplementary water volume or the sewage volume according to experience to maintain the system water volume and control the concentration ratio. After adjustment, whether the concentration ratio is controlled accurately or not, we must wait until the next analysis to understand. If the evaporation of water changes during this...
