Concentrated hydrochloric acid (mass fraction is about 37%) is extremely volatile, so hydrogen chloride gas will volatilize after the container containing concentrated hydrochloric acid is opened, and combine with water vapor in the air to produce small hydrochloric acid droplets, causing acid to appear above the bottle mouth. Fog, during the transportation of hydrochloric acid, due to vibration and bumps, part of the sealing cover will be loosened, resulting in the volatilization of hydrochloric acid and the formation of acid mist with water vapor in the air. When workers are unloading the goods, the human body is directly exposed to acid mist, which can cause acute poisoning , for this reason, provide a kind of hydrochloric acid safe transportation method, improve the safety of hydrochloric acid transportation process

Embodiment Construction
[0026] use figure 1 and figure 2 A kind of hydrochloric acid safe transportation method of the present invention is described as follows.
[0027] Such as figure 1 and figure 2 Shown, a kind of hydrochloric acid safe transportation method of the present invention, this method comprises the steps:
[0028] S1: Cool down the hydrochloric acid to between 0° and 10° to make the hydrochloric acid less volatile and improve the safety of hydrochloric acid transportation;
[0029] S2: Inject the cooled hydrochloric acid in S1 into the hydrochloric acid storage tank for storage, and store the hydrochloric acid in a special hydrochloric acid storage tank to avoid or reduce the leakage of hydrogen chloride gas generated by the volatilization of hydrochloric acid;
[0030] S3: Cover the hydrochloric acid storage tank filled with hydrochloric acid in S2 with a bag with a slaked lime layer, so that the overflowing hydrogen chloride and slaked lime can be neutralized to prevent hydroge...

The invention belongs to the technical field of hydrochloric acid transportation and particularly relates to a hydrochloric acid safety transportation method. The method comprises the following stepsof cooling hydrochloric acid to 0 DEG C-10 DEG C to enable the hydrochloric acid not to be volatilized easily; filling the cooled hydrochloric acid into a hydrochloric acid storage tank for storage; sleeving the hydrochloric acid storage containing hydrochloric acid with a bag with a slaked lime layer; transporting the hydrochloric acid storage tank through a special hydrochloric acid transport vehicle and spraying a hydrochloric acid corrosion inhibitor to a carriage of the hydrochloric acid transport vehicle; arranging a graphite modified polypropylene falling-film absorber in the hydrochloric acid transport vehicle to absorb volatilized hydrogen chloride gas; paving a floor of the carriage of the hydrochloric acid transport vehicle with ice blocks to lower the temperature and arrangingan air conditioner in the carriage used for slowing down melting of the ice blocks through cold air. Through the hydrochloric acid safety transportation method, volatilization of hydrochloric acid canbe effectively inhibited in the transportation process, the volatilized hydrogen chloride gas is fully absorbed, the hazard caused by overflowing hydrogen chloride gas is reduced, and the transportation safety of hydrochloric acid is improved.
Description
technical field [0001] The invention belongs to the technical field of hydrochloric acid transportation, in particular to a method for safe transportation of hydrochloric acid. Background technique [0002] The properties of hydrochloric acid are colorless and transparent liquid with a strong pungent smell and high corrosiveness. Concentrated hydrochloric acid (mass fraction is about 37%) is extremely volatile, so hydrogen chloride gas will volatilize after the container containing concentrated hydrochloric acid is opened, and combine with water vapor in the air to produce small hydrochloric acid droplets, causing acid to appear above the bottle mouth. Fog, during the transportation of hydrochloric acid, due to vibration and bumps, part of the sealing cover will be loosened, resulting in the volatilization of hydrochloric acid and the formation of acid mist with water vapor in the air. When workers are unloading the goods, the human body is directly exposed to acid mist, whi...
