Technical Field

[0002] Hydrogen chloride is an important form of chlorine, and is also a very important chemical product and raw material. It is widely used in chemical, petroleum, metallurgy and other industries. It is mainly used in the production of PVC, polyurethane, epoxy resin, silicone, synthetic rubber, chlorofluorocarbons, TiO2 coatings, some agricultural chemicals, building materials and some pharmaceutical preparations. With the development of science and technology, the design and manufacturing technology of hydrogen chloride gas preparation equipment is also constantly improving, but there are still some problems and challenges.

[0003] In the early stage, hydrogen chloride gas was mainly prepared by the reaction of hydrochloric acid and iron powder. This method has simple equipment, but low reaction efficiency and low purity of hydrogen chloride gas. With the development of electrolysis technology, devices for preparing hydrogen chloride gas by electrolysis have emerged. This device can directly obtain high-purity hydrogen chloride gas by electrolyzing salt water, but the equipment cost is relatively high. In recent years, devices for preparing hydrogen chloride gas by reacting hydrochloric acid solution with concentrated sulfuric acid have emerged.

The concentrated sulfuric acid and hydrochloric acid solution are further mixed by the vibration of the guide plate. After long-term use, sulfuric acid will penetrate into the spring assembly. Since the spring reacts with the concentrated sulfuric acid, it may cause damage to the spring, thereby affecting the normal use of the device and affecting the productivity of hydrogen chloride gas.

[0044] A first support block 461 is provided on the first limiting ring 46, and a second support block 471 is provided on the second limiting ring 47.

The stirring motor 41 drives the rotating seat 42 to rotate, and the rotating seat 42 drives the synchronous wheel 44 to rotate. The synchronous wheel 44 drives the transmission gear 45 to rotate through the connecting rod 48. Since the transmission gear 45 is meshed with the auxiliary gear 434, the stirring rod 43 is driven to rotate through the cooperation between the power transmission gear and the auxiliary gear 434. Since the axis of the stirring rod 43 deviates from the axis of the first limiting ring 46 and the axis of the second limiting ring 47, the stirring rod 43 moves away from the rotating seat 42 and rotates and swings in the reactor 2 under the cooperation of the first universal ball head 431 and the first limiting ring 46 and the cooperation of the second universal ball head 432 and the second limiting ring 47, thereby stirring the mixed solution in the reactor 2, promoting heat conduction in the mixed solution and promoting the overflow of hydrogen chloride gas, thereby improving the productivity of hydrogen chloride gas.

[0048] Example 2 like Figure 6 and Figure 7 As shown, this embodiment is different from the embodiment 1 in that the guide plate 8 arranged in the reaction kettle 2 is replaced by a spiral plate 11, and the spiral plate 11 plays a role of guiding flow.

[0049] The implementation principle of the industrial hydrogen chloride gas preparation device of the embodiment of the present application is as follows: the concentrated sulfuric acid solution sprayed by the sulfuric acid nozzle 5 and the hydrochloric acid solution sprayed by the hydrochloric acid nozzle 6 meet in the air and then fall into the spiral plate 11. The spiral plate 11 increases the contact area between the concentrated sulfuric acid solution and the hydrochloric acid solution and plays a guiding role for the mixed solution. Since the spiral plate 11 can play a role of heat preservation, the temperature inside the spiral plate 11 is relatively high, which can make more hydrogen chloride gas overflow from the mixed solution, thereby improving the productivity of the hydrogen chloride gas. The hydrogen chloride gas overflowing from the structure below the reactor 2 needs to pass through the spiral plate 11 before being collected, so that the collected hydrogen chloride can be relatively dry.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
