Description

technical field [0001] The invention relates to the technical field of preparation of chemical solutions, in particular to an acid solution preparation device capable of continuously monitoring the pH value and a monitoring and preparation method thereof. Background technique [0002] At present, the preparation of acidic solutions used in indoor oil and gas field chemical treatment research at home and abroad generally adopts a manual operation method. It is to weigh a small amount of dry powder ingredients (such as calcium carbonate, etc.) and pour them directly into the acidic solvent in a non-metal container. With continuous stirring, the acidic solution and the ingredients undergo a sufficient chemical reaction to form an acidic solution. During the formation of the acidic solution, a large amount of gas (such as CO 2 ) and containing metal ions (such as Ca + etc.), the gas will volatilize naturally (or be exhausted by the exhaust fan) and the foam will overflow from t...

Problems solved by technology

[0003] Therefore, the disadvantages of the method of artificially preparing the acidic solution are: (1) it is necessary to continuously weigh and add ingredients by hand many times, which increases the labor intensity of the operation; (2) when the volatile gas and a large amount of foam produced during the chemical reaction burst The splashing of acid is harmful to the human body, and the waiting time for the natural bursting and elimination of the foam in the liquid preparation container is long, resulting in a long total time for the preparation of the solution; (3) relying on the manual comparison of the color of the test paper to obtain the pH value of the acidic solution, large error
