Background
In the chemical production field, for example, in the preparation of o-chlorotoluene, chlorine gas needs to be introduced into a reaction kettle to complete the reaction, and finally the required product is obtained. Chlorine is generally stored in an actual production workshop through a liquid chlorine steel cylinder, the change of the external environment temperature of the chlorine steel cylinder directly influences the vaporization quantity of the liquid chlorine, and particularly when the temperature is too low, the vaporization quantity of the liquid chlorine is seriously insufficient, so that the chlorination is abnormal; liquid chlorine cannot be vaporized in time and cannot be completely vaporized into gas, so that the reaction of the system is influenced. At present, people mainly increase the vaporization amount of chlorine gas, connect a plurality of chlorine bottles in parallel, or heat the chlorine bottles, such as spraying water, baking by an electric furnace, an infrared lamp and the like, and the cost is particularly high. The existing direct chlorination reaction process using liquid chlorine as raw material basically includes the processes of vaporization of liquid chlorine, chlorination reaction and capture of low-boiling point vaporized products. The liquid chlorine vaporization process refers to a process of obtaining chlorine steam by heat exchange between liquid chlorine and a heat medium through a vaporization device, the heating medium adopted in the prior engineering is generally water vapor, and a few of the heating media adopt hot water or electric heating. The vaporized chlorine enters the using equipment after being stabilized by the buffer tank.
During the chlorination reaction, chlorine gas is needed to be introduced, the liquid chlorine is converted into gas through a set of device, and the chlorination reaction is realized if the liquid chlorine is introduced into a reaction tank. In the prior art, liquid chlorine is gasified by a vaporizer, the temperature of gas discharged by the vaporizer is low, the chlorine introducing process is not easy to control, and a pipe is easy to block.
