Problems solved by technology
[0003] However, some existing hydrogen chloride gas preparation equipment does not stir the mixed solution of concentrated sulfuric acid and hydrochloric acid during production, thereby reducing the dehydration effect of concentrated sulfuric acid, and the waste liquid produced by the preparation of hydrogen chloride gas is dilute sulfuric acid, which endangers the health of workers. Good health, lower safety factor

Embodiment Construction
[0028] use Figure 1 to Figure 7 The preparation process of a kind of hydrogen chloride gas of the present invention is described as follows.
[0029] like Figure 1 to Figure 7 Shown, the preparation technology of a kind of hydrogen chloride gas of the present invention, this technology comprises the steps:
[0030] S1: Take the fluorine rubber hollow balls filled with sodium chloride saturated solution in the two inner cavities, connect the compression springs inside the two fluorine rubber hollow balls, and fix the compression springs with the nozzle at the bottom of the fluorine rubber hollow balls through the lever. Even, the inner diameter of the nozzle is 2mm, and the sodium chloride saturated solution is used to increase the generation of hydrogen chloride; by spraying the sodium chloride saturated solution in the mixture of concentrated sulfuric acid and hydrochloric acid, the water in the sodium chloride saturated solution is firstly mixed with the concentrated sulf...

The invention belongs to the technical field of hydrogen chloride preparation and particularly relates to a preparation technology of hydrogen chloride gas. The technology comprises the following steps: two hollow fluororubber balls with inner cavities full of a sodium chloride saturated solution are taken, compression springs are fixedly connected in the two hollow fluororubber balls, and the compression springs are fixedly connected with spray nozzles at bottoms of the hollow fluororubber balls through driving levers, wherein the inner diameter of the spray nozzles is 2 mm, and the sodium chloride saturated solution is used for increasing the production of hydrogen chloride; the hollow fluororubber balls are mounted between the inner wall of a tower in efficient hydrogen chloride gas preparation equipment and a rubber air bag module, the rubber air bag module is used for extruding the hollow fluororubber balls intermittently to spray the sodium chloride saturated solution; concentrated sulfuric acid is continuously introduced into a concentrated sulfuric acid box on the tower, and introducing hydrochloric acid into a hydrochloric acid spray pipe; a motor on the tower is started to drive a stirring module and the rubber air bag module for hydrogen chloride preparation. By means of the technology, the preparation rate of the hydrogen chloride gas can be improved effectively andthe production of the hydrogen chloride gas can be increased.
Description
technical field [0001] The invention belongs to the technical field of hydrogen chloride preparation, in particular to a preparation process of hydrogen chloride gas. Background technique [0002] Hydrogen chloride, a corrosive non-combustible gas, does not react with water but is easily soluble in water, and often exists in the form of hydrochloric acid fumes in the air. Soluble in ethanol and ether, also soluble in many other organic substances; soluble in water, at 25°C and 1 atmospheric pressure, 1 volume of water can dissolve 503 volumes of hydrogen chloride gas. Dry hydrogen chloride is chemically very inert. Alkali metals and alkaline earth metals are flammable in hydrogen chloride, and sodium emits a bright yellow flame when it burns. Industrial hydrochloric acid is often slightly yellow, mainly due to the presence of ferric chloride. In industrial production, hydrogen chloride gas can be obtained by the following three methods: hydrogen chloride gas can be obtain...
