Safe concentrated acid adding control device

Abstract

The invention provides a safe concentrated acid adding control device which comprises an acid bottle and a reagent barrel. The acid bottle is connected with the reagent barrel through a liquid discharging pipe, and purified water is contained in the bottle. A buffer bottle is connected with a compressed air pipeline through an air entraining pipeline, a ball valve and a pressure gauge are arrangedon the air entraining pipeline, and a bottom end of the air entraining pipeline is inserted below a liquid level of the purified water. The buffer bottle is connected with the acid bottle through a pressurizing pipe, one end of the pressurizing pipe extends into the buffer bottle and is located above the liquid level, and another end extends into the acid bottle and is located above the liquid level. The acid bottle is further provided with a pressure relief pipe communicated with the atmosphere, and a pressure relief valve is installed on the pressure relief pipe. The invention provides a safe and rapid concentrated acid adding device, operators are prevented from being burnt by acid due to misoperation in the manual handheld acid adding process, and risks are avoided; the volatilizationof fuming acids such as hydrochloric acid is reduced, and occupational health hazards suffered by the operators are reduced. The acid adding speed can be monitored through the pressure gauge and adjusted through a valve and a pressure reducing device.

Description

technical field [0001] The invention belongs to an acid adding device, in particular to a safe acid adding device in an acid adding experiment. Background technique [0002] A large amount of acid preparations are needed in the production and analysis of soda ash. When preparing a large amount of acid solutions in the laboratory, it is usually used to add acid in a hand-held acid bottle. Pour each bottle of concentrated acid into the reagent bucket, and then stir evenly. Although the operator wears a full set of acid-base protective equipment during the acid addition process, there are still certain safety hazards. The ideal method is that the personnel do not directly contact the concentrated acid during the acid addition process and maintain a safe distance to operate. Therefore, those skilled in the art want to study a solution that does not require manual operation and can regulate the amount of acid added.
