DETAILED DESCRIPTION
[0011] The present invention is further described through the following specific embodiments.
[0012] Example 1
[0013] A gaseous chloromethane delivery device includes a gaseous chloromethane pipeline 6 connected to a condenser 7, which is connected to a storage tank 8. The storage tank 8 is connected to a feed pump 9, which is then connected to a vaporizer 10 via a pipeline. The vaporizer 10 is connected to a heater 11. The pipeline connecting the gaseous chloromethane pipeline 6 and the heater 11 is equipped with a flow meter 4 and a regulating valve 1. The pipeline connecting the gaseous chloromethane pipeline 6 and the condenser 7 is equipped with a regulating valve 2; the regulating valves 1 and 2 form an interlocking control with the flow meter 4.

[0014] Example 2: Switching during normal production (starting gas phase transport)
[0015] Under the operating conditions of a chloromethane synthesis unit producing 20 t / h of chloromethane and a monomer synthesis unit consuming 35 t / h of chloromethane, open control valve 1 to 5% open. Flowmeter 4 displays 1 t / h. Adjust the opening of control valve 3 to reduce the flow rate on flowmeter 2-5 by 1 t / h. After stabilization for half an hour, adjust control valve 1 again to reduce the flow rate on flowmeter 1-4 to 2 t / h. Simultaneously adjust the openings of control valves 2-2 and 3-3, and reduce the flow rate on flowmeter 2-5 by another t / h. Repeat this process until the flow rate on flowmeter 1-4 reaches 15 t / h.
[0016] Example 3: Switching during normal production (stopping gas phase transport)
[0017] Under the operating conditions of the chloromethane synthesis unit producing 15 t / h of chloromethane, 10 t / h of which is transported in gaseous form, and the monomer synthesis unit consuming 30 t / h of chloromethane, close regulating valve 1, reduce the flow rate on flowmeter 4 to 9 t / h, open regulating valve 3, increase the flow rate on flowmeter 25 by 1 t / h, and after stabilizing for half an hour, adjust the flow rate again by 1 t / h. Repeat this process until the flow rate on flowmeter 4 drops to 0, then close regulating valve 1.
