Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

As shown in Figures 1, 2, 3 and 4, the present invention provides a raw liquid treatment device, which includes a tank 1 and a cover 3 installed on the tank 1 through a sealing ring 2. The tank 1 The bottom of the tank is provided with a water inlet pipe 4 and an air inlet pipe 5, and the air inlet pipe 5 is connected to a scroll air pipe 6. The surface of the scroll air pipe 6 is provided with air holes 7, and the tank 1 is provided with a flap inside. Valve device 8, a water outlet pipeline 9 is provided on the surface of the tank 1 located on the bottom side of the flap valve device 8;

The bottom of the tank 1 in this device is provided with a heating device. The heating device can be realized by general heating means. A gas chromatograph connected to the pipe at the top of the tank will regularly detect the purged gas in the raw liquid treatment device. Gas, if carbon dioxide is detected, the heating and cooling of the raw liquid treatment device will be repeated. If hydrogen sulfide is detected, the process of oxidation and precipitation will occur;

The tank 1 of the raw liquid treatment device is divided into two chambers by the flap valve device 8. The bottom chamber of the flap valve device 8 is the concentrated part of the inlet and outlet pipelines. The raw liquid undergoes a heating reaction in the chamber entering the bottom of the flap valve device 8. During the reaction process, the flap valve device 8 is in an open state to realize internal gas removal. During the cooling process after heating, the flap valve is in a closed state to prevent the backflow of gas in the gas outlet pipeline. At the same time, when the flap valve device 8 is closed, , further compressing the internal space, causing a pressure difference in the upper and lower spaces of the flap valve device 8, which can quickly guide the flow during purging.

When purging the internal gas, only when the gas at the bottom of the flap valve device 8 reaches a certain pressure, the flap valve device 8 will be automatically opened for exhaust. When sampling the gas chromatograph, a certain time can be obtained. There is a mixture of argon and other impurity gases inside. At the same time, the concentration of the mixture of other impurity gases is high and can be accurately detected by the gas chromatograph. This avoids the problem that when argon is used as the drainage gas, the content of other impurity gases is small. It cannot be accurately detected by gas chromatograph, which improves the accuracy of detection.

The working principle of this device is: in a pure argon working environment, high-purity water is added with hydrogen peroxide to oxidize and precipitate to remove hydrogen sulfide, and the upper solution of the treatment liquid is introduced into the water inlet pipe 4 into the inside of the tank 1 through the manual valve control, and is passed through the heating device After heating, carbon dioxide is removed. After the treatment liquid in tank 1 is cooled, the gas supply device continues to pass in argon gas, and the argon gas in the second raw liquid treatment device is purged to remove methane, etc. in Shencheng in the second principle treatment device. gas to obtain a large amount of raw liquid without hydrogen sulfide, carbon dioxide and methane gas;

The gas expansion in the valve requires real-time pressure relief through the vacuum system. At the same time, manual pressure relief can ensure that the gas that escapes in a single time is quickly cooled when it contacts the space at the top of the flap valve device 8, preventing water vapor from entering the pipeline of the vacuum system. .
