Device for preventing concentrated hydrochloric acid volatilization

Abstract

The invention relates to the technical field of concentrated hydrochloric acid storage, in particular to a device for preventing concentrated hydrochloric acid volatilization. The device comprises anouter bottle body, an inner bottle body is arranged in the outer bottle body, and a condensing cavity is formed between the outer bottle body and the inner bottle body; the two sides of a bottle mouthare provided with a water filling inlet and a water outlet respectively, and one end of the water filling inlet and one end of the water outlet are introduced into the condensing cavity separately; afirst drying pipe is arranged on one side of the exterior of the outer bottle body, an air inlet is formed in one side of the bottom of the first drying pipe, a first exhaust pipe is arranged on thetop of the first drying pipe, and the end, far away from the first drying pipe, of the first exhaust pipe is introduced into the inner bottle body; and a second drying pipe is arranged on the side, opposite to the first drying pipe, of the exterior of the outer bottle body, a second exhaust pipe is arranged on the top of the second drying pipe, the end, far away from the second drying pipe, of thesecond exhaust pipe is introduced into the inner bottle body, and an exhaust outlet is formed in the bottom of the second drying pipe. According to the device for preventing concentrated hydrochloricacid volatilization, the first drying pipe and the second drying pipe are arranged on the two sides of the outer bottle body, therefore, air in a bottle keeps dry, and concentrated hydrochloric acidvolatilization is prevented.

Description

technical field [0001] The invention relates to the technical field of concentrated hydrochloric acid storage, in particular to a device for preventing the volatilization of concentrated hydrochloric acid. Background technique [0002] Hydrochloric acid is an aqueous solution of hydrochloric acid gas. Hydrochloric acid is an important basic chemical raw material. It is widely used. Concentrated hydrochloric acid is very volatile in the air. It combines with water vapor to form small droplets of hydrochloric acid, which produces white mist in the air. The pungent odor of present concentrated hydrochloric acid cannot effectively isolate the contact of concentrated hydrochloric acid with the water in the air, and cannot effectively prevent the volatilization of concentrated hydrochloric acid. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming that the prior art cannot effectively prevent the volatilization of concentrated hydro...
