Storage tank for hydrochloric acid production and transportation

Abstract

The utility model discloses a storage tank for hydrochloric acid production and transportation, which comprises a tank body, the top of the tank body is inserted with a liquid delivery pipe penetrating into the tank body, and the liquid delivery pipe is used for delivering hydrochloric acid into the tank body or delivering the hydrochloric acid out of the tank body; a liquid feeding pipe is arranged in the tank body, a first valve located above the tank body is arranged on the liquid feeding pipe, a liquid inlet hopper is communicated with the top of the liquid feeding pipe and used for filling hydrochloric acid into the tank body, a liquid discharging pipe is communicated with the position, located below the first valve, of the left side of the liquid feeding pipe, and a second valve is arranged on the liquid discharging pipe. Through the arrangement of the liquid feeding pipe and the partition plate, the external extrusion resistance of the tank body is improved to a certain degree, meanwhile, when hydrochloric acid is injected into the tank body to be transported, due to the fact that the tank body is not filled with the hydrochloric acid, the hydrochloric acid shakes in the tank body to generate surges in the transportation process, the partition plate can effectively isolate the surges, and therefore the hydrochloric acid storage tank can be used for storing hydrochloric acid. And the peak value of surge is reduced, and the stability of the tank body during transportation is enhanced.

Description

Technical Field

[0001] The utility model relates to the field of hydrochloric acid storage tanks, in particular to a storage tank for hydrochloric acid production and transportation. Background Art

[0002] Concentrated sulfuric acid is a sulfuric acid aqueous solution with a mass fraction greater than or equal to 70%. Concentrated sulfuric acid is highly corrosive: under normal pressure, boiling concentrated sulfuric acid can corrode all metals except iridium and ruthenium. The number of metal elements it can corrode even exceeds that of aqua regia. Sulfuric acid is highly oxidizing at high concentrations, which is one of the biggest differences between it and dilute sulfuric acid. It is also dehydrating, non-volatile, acidic and hygroscopic.

[0003] Hydrochloric acid is stored in a storage tank before transportation, and the volume of the hydrochloric acid is required not to exceed 80% of the storage tank. This causes the hydrochloric acid during transportation to affect surge and sway in the storage tank, thus challenging the stability of the storage tank. Therefore, a storage tank for hydrochloric acid production and transportation is proposed. Utility Model Content

[0006] The utility model discloses a storage tank for hydrochloric acid production and transportation, comprising a tank body, wherein the top of the tank body is plugged with a liquid delivery pipe which penetrates into the tank body and is used for delivering hydrochloric acid into the tank body or delivering hydrochloric acid out of the tank body;

[0007] The liquid delivery pipe is provided with a first valve located above the tank body, and the top of the liquid delivery pipe is connected to a liquid inlet hopper for supplying hydrochloric acid to the tank body;

[0008] A liquid discharge pipe is connected to the left side of the liquid delivery pipe and is located below the first valve. The liquid discharge pipe is provided with a second valve.

[0009] Close the first valve, open the second valve, and connect the chemical pump to the discharge pipe for suction to extract the hydrochloric acid in the tank;

[0010] A partition is fixedly provided on the outside of the liquid delivery pipe, and the other end of the partition is fixedly connected to the inner wall of the tank body.

[0011] As a preferred technical solution of the present invention, the bottom of the liquid delivery pipe is fixedly connected to the inner bottom wall of the tank body, and a through hole is opened at the lower part of the exterior of the tank body.

[0012] As a preferred technical solution of the present invention, the exterior of the tank body is covered with a buffer sleeve, and the thickness of the buffer sleeve is consistent with the wall thickness of the tank body.

[0013] As a preferred technical solution of the present invention, a protective cylinder is fixedly provided on the top of the tank body, the protective cylinder is located outside the liquid delivery pipe, and the liquid discharge pipe passes through the protective cylinder.
