Patent ID: 7501055

Claim:
An on-line injection, reuse and destruction system for gas, comprising: a gas-introducing device for introducing at least one gas comprising an inlet for injection of at least part of the gas and a check valve for draining liquid; a first check valve connected to the gas-introducing device; an injector connected to the first check valve for drawing the gas through the first check valve and mixing the gas with a liquid; a gas-liquid separation device connected to the injector for separating liquid from the mixed gas and liquid from the injector; and an ozone destruction device connecting the gas-liquid separation device and the gas-introducing device for supplying at least part of the gas to the gas-introducing device and destroying at least part of ozone of the gas, wherein the gas is ozone and the liquid is water, the gas-introducing device comprises an upper outlet connected to the first check valve; the injector having an gas inlet for connecting to the first check valve; the gas-liquid separation device having a conduit installed therein, with the lower end of the conduit connected to the outlet of the injector while the upper end thereof extends to near the top inside the gas-liquid separation device; a water outlet arranged near a bottom of the gas-liquid separation device and a gas outlet arranged near the top of the gas-liquid separation device, and the ozone destruction device with its interior is divided into an upper section and a lower section in a gas communication manner, and the top of the upper section is in air communication with the surroundings and the upper section is provided with an ozone destruction medium, and the pipe is connected to the gas outlet of the gas-liquid separation device, passing through the lower section of the ozone destruction device and entering the leakage check valve device; and an outer pipe is arranged so that it is coaxial with the part of the pipe that connects the ozone destruction device and the gas-introducing device.
