Abstract
The utility model discloses graphitic equipment producing dry hydrogen chloride by using concentrated sulphuric acid to desorb hydrochloric acid. The graphitic equipment comprises an equipment body; and a dry hydrogen chloride gas outlet, a concentrated sulphuric acid inlet, a mixed acid outlet, a cooling water inlet, a cooling water outlet and a hydrochloric acid inlet are formed on the equipment body. The utility model adopts the principle that concentrated sulphuric acid and hydrochloric acid are mixed to lead the hydrogen chloride gas in the hydrochloric acid to volatilize out, and then the hydrogen chloride gas volatilized out of the hydrochloric acid is dried in virtue of the strong water absorbability of the concentrated sulphuric acid. The graphitic equipment provided by the utility model has simple operating process, and is suitable for mass production; and the produced hydrogen chloride gas has high purity and low cost, and is beneficial to environmental protection at the same time.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, is specifically related to a kind of vitriol oil and takes off and analyse hydrochloric acid and produce the dry hydrogen chloride graphite equipment.
Background technology
What the at present industrial method of producing hydrogenchloride was common has three kinds:
First kind is with the chlorine and the hydrogen synthesising hydrogen that electrolyze table salt and obtain, and this method must be supporting with electrolysis, and the purity of the hydrogen chloride gas of producing is not high.Second kind is with the by-product HCl gas of producing products such as chlorobenzene, Mono Chloro Acetic Acid, and this method is difficult for a large amount of acquisition hydrogenchloride, and gas is impure.The third method is the synthesizing chlorinated hydrogen of hydrogen and chlorine, and it is purer to obtain gas ratio, but facility investment is bigger.Present method is to use technical hydrochloric acid to take off suction and produces HCl, and the hydrogen chloride gas purity that this method is produced is high and dry, but because sulfuric acid and hydrochloric acid belong to strong acid, the equipment of common material easily causes corrosion.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, provides a kind of vitriol oil of erosion resistance to take off to analyse hydrochloric acid to produce the dry hydrogen chloride graphite equipment.
The technical solution adopted in the utility model: a kind of vitriol oil takes off analyses hydrochloric acid product dry hydrogen chloride graphite equipment, described graphite equipment comprises apparatus body, the apparatus body top is provided with the dry hydrogen chloride gas outlet, the body upper right side is provided with vitriol oil import, the body bottom is provided with the nitration mixture outlet, the body lower left is provided with entrance of cooling water, and the entrance of cooling water upper wall is provided with cooling water outlet, and the cooling water outlet upper wall is provided with the hydrochloric acid import; The described vitriol oil takes off analyses hydrochloric acid and produces between the vitriol oil import of dry hydrogen chloride graphite equipment and the hydrochloric acid import and contain filler and mixing tank, and the filler between vitriol oil import and the hydrochloric acid import partly contains sieve plate.
As preferably: the material between vitriol oil import and the hydrochloric acid import is a graphite.
The vitriol oil import of vitriol oil slave unit upper end enters, and with the hydrochloric acid thorough mixing that enters from the hydrochloric acid import, the cooling of mixed nitration mixture falling liquid film access arrangement lower end is discharged by the nitration mixture outlet after the process packing section.Nitration mixture is in mixing process, and the hydrogen chloride gas in the hydrochloric acid evaporates and up passes through packing section, and at packing section and the abundant contact drying of the vitriol oil, dried hydrogen chloride gas is discharged by the outlet of equipment top hydrogen chloride gas.The import of the utility model hydrochloric acid is equivalent to nahlock cellular type sulfuric acid dilution device with the structure and the principle of lower section.
Beneficial effect: the utility model has solved the deficiencies in the prior art, provide a kind of vitriol oil to take off and analyse hydrochloric acid product dry hydrogen chloride graphite equipment, the hydrogenchloride made from this equipment not only purity height and cost is low, suitable for mass production, material between sulfuric acid import simultaneously and the hydrochloric acid import is a graphite, graphite has erosion resistance preferably, has prolonged the work-ing life of equipment.Chloride ion-containing is less in the nitration mixture of discharging in the utility model use, can be used as the commercial sulphuric acid not high to the sulfuric acid quality requirements, and perhaps industrial nitration mixture is made in the collocation of continuation and mixed in hydrochloric acid.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
