[0024] Such as Figure 1As shown in the figure, the present application provides a hydrogen chloride supply device for quartz sand purification, which includes a main gas supply cylinder 1, a spare gas cylinder 2, a main gas supply pipe 3, and a gas supply branch pipe 4. One end of the main gas supply pipe 3 is connected to the main gas supply cylinder 1, and the other end of the main gas supply pipe 3 is connected to a chlorination reaction tank in the prior art. The spare gas cylinder 2 is connected to the main gas supply pipe 3 through the gas supply branch pipe 4. A first pressure reducing valve 5 and a first solenoid valve 6 are provided on the main gas supply pipe 3. Both the first pressure reducing valve 5 and the first solenoid valve 6 are located between the main gas supply cylinder 1 and the gas supply branch pipe 4, and the first solenoid valve 6 is in front of the first pressure reducing valve 5. A second pressure reducing valve 7 and a second solenoid valve 8 are provided on the gas supply branch pipe 4, and the second solenoid valve 8 is in front of the second pressure reducing valve 7. During use, the first solenoid valve 6 is opened, the second solenoid valve 8 is closed, the first pressure reducing valve 5 is adjusted to the required output pressure, and gas is supplied through the main gas supply cylinder 1. When the gas volume in the main gas supply cylinder 1 is insufficient, the second solenoid valve 8 is opened, the first solenoid valve 6 is closed, and the second pressure reducing valve 7 is adjusted to the required output pressure. At this time, gas is supplied by the spare gas cylinder 2. By providing the main gas supply cylinder 1 and the spare gas cylinder 2 to supply hydrogen chloride gas to the chlorination reaction tank of quartz sand, the spare gas cylinder 2 is enabled when the gas volume in the main gas supply cylinder 1 is insufficient. Compared with the prior art, it effectively avoids material loss during the period due to frequent gas cylinder replacement. Through the settings of the first pressure reducing valve 5 and the second pressure reducing valve 7, the hydrogen chloride supply air pressure is stabilized.

[0025] As Figure 1 shown, the main gas supply cylinder 1 is connected with a first inlet pipe 9, and a first check valve 10 is provided on the first inlet pipe 9. The spare gas cylinder 2 is connected with a second inlet pipe 11, and a second check valve 12 is provided on the second inlet pipe 11. Hydrogen chloride gas is input into the main gas supply cylinder 1 through the first inlet pipe 9 and into the spare gas cylinder 2 through the second inlet pipe 11 to supplement the gas volume in the main gas supply cylinder 1 and the spare gas cylinder 2. Among them, the first check valve 10 and the second check valve 12 can prevent the reverse flow of hydrogen chloride gas.

[0026] As Figure 1 shown, a first pressure gauge 13 is provided on the main gas supply cylinder 1, and a second pressure gauge 14 is provided on the spare gas cylinder 2. The pressure of the hydrogen chloride gas in the main gas supply cylinder 1 is measured through the first pressure gauge 13 to judge the gas volume in the main gas supply cylinder 1, and the pressure of the hydrogen chloride gas in the spare gas cylinder 2 is measured through the second pressure gauge 14 to judge the gas volume in the spare gas cylinder 2.

[0027] As Figure 1 shown, the first pressure gauge 13 and the second pressure gauge 14 are electronic pressure gauges, and the electronic pressure gauges can emit signals. In this embodiment, both the first pressure gauge 13 and the second pressure gauge 14 are Wi-Fi intelligent pressure gauges, which can send the measured pressure values to a designated server or receiving end using the Wi-Fi network.

[0028] As Figure 1As shown, it further includes a controller (not shown in the figure). The controller is electrically connected to the first pressure gauge 13, the second pressure gauge 14, the first solenoid valve 6, and the second solenoid valve 8 respectively. The controller can receive the signals transmitted by the first pressure gauge 13 and the second pressure gauge 14, and control the opening and closing of the first solenoid valve 6 and the second solenoid valve 8 according to the signals of the first pressure gauge 13 and the second pressure gauge 14. Specifically, when the first pressure gauge 13 measures that the air pressure in the main gas supply cylinder 1 is lower than the set threshold, the first pressure gauge 13 sends a signal to the controller, and the controller controls the first solenoid valve 6 to close and the second solenoid valve 8 to open according to the signal transmitted by the first pressure gauge 13. When the second pressure gauge 14 measures that the air pressure in the spare gas cylinder 2 is lower than the set threshold, the second pressure gauge 14 sends a signal to the controller, and the controller controls the second solenoid valve 8 to close and the first solenoid valve 6 to open according to the signal transmitted by the second pressure gauge 14.

[0029] As Figure 1 As shown, a first intake valve 15 is provided on the first intake pipe 9. The first intake valve 15 is located behind the first check valve 10. A second intake valve 16 is provided on the second intake pipe 11. The second intake valve 16 is located behind the second check valve 12. When the gas volume in the main gas supply cylinder 1 is insufficient, hydrogen chloride gas can be input into the main gas supply cylinder 1 by opening the first intake valve 15. When the gas volume in the spare gas cylinder 2 is insufficient, hydrogen chloride gas can be input into the spare gas cylinder 2 by opening the second intake valve 16.

[0030] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
