Description
Technical Field
[0001] The invention relates to the technical field of hydrogen chloride removal, in particular to a mixing ejector and a reaction kettle for removing hydrogen chloride phase and a removal method. Background Art
[0002] Chloride intermediates refer to fatty acid methyl esters, straight-chain hydrocarbons, and aromatic hydrocarbons that contain about 1% hydrogen chloride gas after the chlorination reaction is completed. Before the hydrogen chloride is blown off, they are called chloride intermediates. After the hydrogen chloride is blown off with compressed gas, they are important industrial raw materials and are widely used in industries such as polyvinyl chloride, polyurethane, rubber and plastics, oil products, and pharmaceutical intermediates.
[0003] After chlorination, fatty acid methyl esters, straight-chain hydrocarbons, and aromatic hydrocarbons all need to be blown off with compressed air or nitrogen to remove the hydrogen chloride in the chloride. The current process uses a bubbling process that inserts a pipe from the center of the upper part of the chloride intermediate refining kettle. The bubbling process uses a 10m 3 / h gas compressor gas source, energy consumption 55kw / h. Although in principle, no matter how much energy is consumed and how long it takes to remove hydrogen chloride, the hydrogen chloride content in the chloride intermediate can always meet the standard, but the overall energy consumption is too high, which increases the cost of removing hydrogen chloride. Summary of the invention

[0014] A removal method is also provided, comprising the following steps:
[0015] Online mass calibration: The chloride intermediate continuously enters the mass calibrator through the inlet of the chlorinated intermediate supply pipeline to complete the online mass calibration;
[0016] Passing in the chloride intermediate: after completing the online mass calibration, the chloride intermediate continuously enters the feed nozzle connected to the reactor body through the liquid level pipeline, and enters the reactor body through the discharge nozzle and the through hole on the connecting section, and the gas precipitated from the chloride intermediate is returned to the chlorination reactor from the air pressure balance pipeline, forming an air pressure balance in a connected state with the chlorination reactor;
