Problems solved by technology

[0010] . Due to the large content of additives such as slurry and enzyme in the process liquid, if the flow rate of the process liquid is low, it is easy to cause blockage of the process liquid circulation pipeline;
[0011] . Due to certain changes in the temperature of the process liquid in the working tank, the density of the process liquid will change, which will also lead to changes in the detection accuracy.

Description

technical field [0001] The invention relates to a concentration detection device, in particular to an online continuous concentration detection device for printing and dyeing process liquid. Background technique [0002] At present, in the printing and dyeing mercerizing process, the concentration of alkali in the process solution is controlled manually, that is, the alkali solution with the required concentration is prepared by manual titration. During the operation of the equipment, after the fabric passes through the lye, the concentration of alkali in the lye will naturally decrease due to the adsorption of the fabric. In order to maintain the concentration of alkali in the lye, a certain concentration of concentrated alkali must be manually added to the process solution. In order to maintain the concentration of alkali in the process solution. However, this method is not a real-time and continuous process, and the concentration of lye is very unstable, which may easily...
