Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen halide generators, specifically to a hydrogen halide gas generator. Background Technology

[0002] Hydrogen halides are a class of inorganic compounds formed by covalent bonds between hydrogen atoms and halogen atoms. They are all gases with a pungent odor under standard conditions, readily soluble in water, and their aqueous solutions are called hydrohalic acids, which are common strong acids. Hydrogen halides and their derivatives play an indispensable role in modern industry, scientific research, and daily life.

[0003] Currently, most traditional hydrogen halide gas preparation devices use a jacketed water bath for temperature control. The temperature is transferred from the vessel wall to the center, resulting in a deviation between the temperature at the center of the reactor and the temperature at the edge of the vessel wall. This leads to poor temperature control accuracy and the inability to remove peak heat in a timely manner. Utility Model Content

It forms a dual heat exchange unit with the circulating water chamber 13 and the stirring heat exchange component 40, which can reduce the temperature difference in various parts of the reactor 10 and achieve efficient temperature control.

[0022] like Figure 3 and Figure 7 As shown, the temperature measuring assembly 60 includes a temperature measuring sleeve 61, which seals through the bottom wall of the vessel body 11 and extends into the vessel body 11. A temperature sensor 62 is nested at the top of the temperature measuring sleeve 61.

[0023] In this invention, the temperature of the reaction liquid inside the reactor 10 is transmitted to the temperature sensor 62 by the temperature measuring sleeve 61 and the thermally conductive silicone grease 63, thereby realizing the measurement of the temperature inside the reactor 10. The top of the temperature measuring sleeve 61 is lower than the lowest point of the stirring heat exchange tube 43 to avoid collision between the temperature measuring sleeve 61 and the stirring heat exchange tube 43. The outer side of the temperature measuring sleeve 61 is coated with PFA to prevent the temperature measuring sleeve 61 from being corroded.

[0026] In this invention, during material addition, the PLC controller 14 controls the geared motor 28 to rotate the auger 23, causing the sodium chloride stored in the storage tank 21 to fall evenly through the discharge pipe 22 onto the weighing pan 26 in the quantitative weighing cylinder 24. The weighing pan 26 weighs a fixed amount of sodium chloride. When the set amount is reached, the geared motor 28 stops working. At the same time, the PLC controller 14 controls the servo motor 29 to work, and the servo motor 29 drives the circulating flipper 25 to rotate 180 degrees, so that the weighing pan 26 faces downward. The weighing pan 26 falls and enters the reaction vessel 10 through the feed pipe 27, realizing the quantitative addition of sodium chloride.

[0027] like Figure 1 As shown, the sulfuric acid metering addition component 30 includes a sulfuric acid metering pump 31.
