when the device works, hydrochloric acid and concentrated sulfuric acid respectively enter the cavities of the corresponding spraying trays 4 through a hydrochloric acid feeding pipe and a concentrated sulfuric acid feeding pipe and are sprayed out through a spraying port, the sprayed hydrochloric acid and the sprayed concentrated sulfuric acid rebound under the action of a third spring 8 after impacting a pressing plate 9, the hydrochloric acid and the concentrated sulfuric acid are enabled to impact with each other to be mixed, liquid diffusion after the hydrochloric acid and the concentrated sulfuric acid impact the pressing plate 9 is utilized, the rebound force obtained after the pressing plate 9 compresses the third spring 8 is utilized, the contact area of the hydrochloric acid and the concentrated sulfuric acid is enlarged, the impact force of the hydrochloric acid and the concentrated sulfuric acid is increased, the hydrochloric acid and the concentrated sulfuric acid are enabled to be mixed to generate more hydrogen chloride gas, and the; hydrochloric acid and concentrated sulfuric acid can generate hydrogen chloride gas and release a large amount of heat when mixed, after the hydrogen chloride gas is accumulated too much in the box body 1, the rotating plate 62 is pushed to rotate so as to open the exhaust hole 2, the hydrogen chloride gas is discharged through the air pump, when the rotating plate 62 rotates, the supporting plate 63 also rotates along with the rotating plate 62, at the moment, the two spraying trays 4 slide upwards under the thrust of the first spring 5, the spraying time of the hydrochloric acid and the concentrated sulfuric acid is controlled through the controller, the effect of intermittent spraying of the hydrochloric acid and the concentrated sulfuric acid is achieved, when the hydrochloric acid and the concentrated sulfuric acid are not sprayed, the rotating plate 62 resets through the elasticity of the second spring due to the reduction of the air pressure in the box body 1, the controller controls the spraying of the hydrochloric acid and the concentrated sulfuric acid again, the rotating plate 62 repeatedly rotates and resets, so that the spraying trays 4 repeatedly slide up and down, the pressure regulating device 6 pushes the spraying, the spraying tracks of the hydrochloric acid and the concentrated sulfuric acid are more disordered, the contact times of the hydrochloric acid and the concentrated sulfuric acid are more, the contact mixing degree of the hydrochloric acid and the concentrated sulfuric acid is improved, and the efficiency of generating hydrogen chloride gas by mixing the hydrochloric acid and the concentrated sulfuric acid is improved; along with the continuous progress of the reaction, the mixed solution on the partition plate 7 is more, the mixed solution is pressed down through the pressing plate 9 to be flapped, and the mixed solution is extruded and stirred by the pitch change in the springing process of the third spring 8, so that the mixing degree of the mixed solution is further improved, and the utilization rate of the raw materials of hydrochloric acid and concentrated sulfuric acid is improved; meanwhile, as the elastic pitch of the third spring 8 is increased, liquid flows into the space below the partition plate 7 in the box body 1 from the gap between the third spring 8 through the through hole; the gaseous hydrogen chloride that has heat that is taken away by the air pump is discharged through spiral pipe 3, and gaseous exhaust in-process, heat effect mixed liquid in the space below baffle 7 in box 1 heats mixed liquid, makes mixed liquid generate hydrogen chloride gas again, has further improved the utilization ratio of hydrochloric acid and concentrated sulfuric acid raw materials, and hydrogen chloride gas gets into the gas holder at last and stores.
