[0012] The technical solution of this utility model will be clearly and completely described below with reference to Figures 1-2 in the embodiments of this utility model: An automatic gas regulation system for a hydrogen chloride synthesis furnace includes a hydrogen regulation circuit, a chlorine regulation circuit, and a ratio device 4. The hydrogen regulation circuit includes a hydrogen regulator 1, a hydrogen regulation valve 2, and a hydrogen flow transmitter 3 connected in sequence. The output end of the hydrogen flow transmitter 3 is connected to the input end of the hydrogen regulator 1. The hydrogen flow transmitter 3 is used to detect the hydrogen flow rate entering the hydrogen chloride graphite synthesis furnace and transmit the detection signal to the hydrogen regulator 1.

The chlorine regulator 5 controls the opening degree of the chlorine regulating valve 6 according to the signal output by the ratio meter 4 and the detection signal transmitted by the chlorine flow transmitter 7.

[0015] During operation, an externally input hydrogen flow rate setpoint is sent to hydrogen regulator 1. Hydrogen flow transmitter 3 monitors the hydrogen flow rate in real time and feeds the signal back to hydrogen regulator 1. Hydrogen regulator 1 controls the opening of hydrogen regulating valve 2 based on the deviation between the setpoint and the feedback signal, stabilizing the hydrogen flow rate near the setpoint. Simultaneously, hydrogen regulator 1 transmits the signal to ratio meter 4. Ratio meter 4 processes the signal according to the set hydrogen-chlorine ratio and transmits it to chlorine regulator 5 as a reference for setting the chlorine flow rate. Chlorine flow transmitter 7 monitors the chlorine flow rate in real time and feeds it back to chlorine regulator 5. Chlorine regulator 5 controls the opening of chlorine regulating valve 6 based on the deviation between the signal output from ratio meter 4 and the feedback signal, ensuring that the chlorine flow rate follows the hydrogen flow rate changes and maintaining a stable ratio between the two.
