Automatic control method for hydrochloric acid solution dilution technique

Abstract

The invention relates to an automatic process control method, in particular to an automatic control method for the dilution process of hydrochloric acid solution during the process of diluting concentrated hydrochloric acid used for pickling bone grains into dilute hydrochloric acid in the gelatin production process. The automatic control method of the hydrochloric acid solution dilution process comprises the following steps: 1) system start; 2) input process parameters; 3) mixing; 4) adding air to stir; 5) detection; 6) outputting qualified dilute hydrochloric acid. The automatic control method of the hydrochloric acid solution dilution process of the present invention has simple process, high degree of automation of the process flow, convenient operation and high hydrochloric acid solution dilution precision. The method of the invention can realize the automatic control of the hydrochloric acid solution dilution process.

Description

technical field [0001] The invention relates to an automatic process control method, in particular to an automatic control method for the dilution process of hydrochloric acid solution during the process of diluting concentrated hydrochloric acid used for pickling bone grains into dilute hydrochloric acid in the gelatin production process. Background technique [0002] The raw material for gelatin production is aggregate and then the pre-soaking and pickling process is required after the bone grains are made. This process requires the use of dilute hydrochloric acid solution with a concentration of 3%-4.5%, so the purchased 30% concentrated HCL solution must be diluted. The process equipment is concentrated acid storage tank, dilution buffer tank, concentrated acid pump, dilute acid pump and other equipment, and purified water is directly mixed with concentrated acid in the dilution buffer tank to achieve the purpose of dilution. The traditional acid solution configuration c...

AI Technical Summary

Problems solved by technology

The traditional acid solution configuration completely relies on manual control to dilute 30% concentrated hydrochloric acid into 3%-4.5% dilute hydrochloric acid. Due to manual control, it is difficult to accurately configure the required concentration of dilute hydrochloric acid solution, which affects the quality of gelatin products, and the work efficiency is very low.
