Method and device for improving primary conversion rate of methanol in synthesized chloromethane

The invention discloses a method and a device for improving the primary conversion rate of methanol in synthesized chloromethane. The method for improving the primary conversion rate of methanol in synthesized chloromethane comprises the following steps: 1) adding hydrogen chloride gas, methanol and a high-temperature catalyst solution into an ejector to obtain a reaction fluid; and 2) pressurizing the reaction fluid by an ejector, ejecting the pressurized reaction fluid via the ejector, and allowing the ejected reaction fluid to enter a reactor through a feed distribution pipe for a reaction.Meanwhile, the invention also discloses the device for improving the primary conversion rate of methanol in the synthesized chloromethane. By using the treatment method, the primary conversion rate of methanol can be improved, so the productivity of a chloromethane synthesis device is further improved, and the unit consumption of methanol is reduced. 本发明公开了一种提高合成氯甲烷中甲醇一次转化率的方法及装置。这种提高合成氯甲烷中甲醇一次转化率的方法，包括以下步骤：1)将氯化氢气体、甲醇和高
