Embodiment 1

[0025] Such as Figure 1-Figure 3 As shown, a self-gas-liquid separation device includes a high-purity chlorine dioxide generator 1, a raffinate storage tank 2, a raffinate pump 3, a waste water treatment tank 4, a circulation pump 5 and a water ejector 6 connected in series in sequence. The high-purity chlorine dioxide generator 1 includes a chlorine dioxide generator 7 , a buffer tank 8 and special-shaped U-shaped pipes 9 connected in sequence.

[0026] On this basis, preferably: the raffinate pump 3 is connected to the waste water treatment tank 4 through the first pipeline 201, the water injector 6 is connected to the waste water treatment tank 4, and the water injector 6 is also connected through the second pipeline 202 It is connected with the high-purity chlorine dioxide generator 1, and the chlorine dioxide generator 7 in the high-purity chlorine dioxide generator 1 is connected with the raw material input pipeline, and the third pipe is passed between the raw material...

Embodiment 2

[0033] A method for self-separation of gas-liquid by using the device for self-separation of gas-liquid in embodiment 1, comprising the steps of:

[0034] The high-purity chlorine dioxide generator 1 controls the temperature through the electromagnetic induction heater, and controls the negative pressure through the water injector 6, and the chlorine dioxide gas and the residual liquid after the reaction produced by the reaction are respectively placed in the high-purity chlorine dioxide generator 1. The upper and lower parts are self-separated, wherein, in the upper part of the high-purity chlorine dioxide generator 1, the pure chlorine dioxide gas is separated by the buffer tank 8, and then directly pumped out by the water injector 6 and sent to the water body to be treated. The lower part of the chlorine dioxide generator 1, after the reaction, the residual liquid passes through the special-shaped U-shaped pipe 9, and the residual liquid is separated by the change of pressur...

Embodiment 3

[0037] A kind of method adopting the device described in embodiment 1 to carry out automatic gas-liquid separation, comprises the steps:

[0038] The high-purity chlorine dioxide generator 1 is controlled at 56°C by an electromagnetic induction heater, and the high-purity chlorine dioxide produced by the reaction passes through the buffer tank 8 on the upper part of the high-purity chlorine dioxide generator 1 at a gas velocity ratio of 76:1. Next, pure chlorine dioxide gas is obtained, and the chlorine dioxide gas from the residual liquid storage tank 2 is sent to the water body to be treated through the water injector 6; the residual liquid produced after the reaction passes through the special-shaped chlorine dioxide generator 1 bottom U-shaped pipe 9, the negative pressure in the control pipe is >9.5KPa, the separated raffinate flows into the raffinate storage tank 2 by itself, and is sent to the waste water treatment pool 4 or the chlorine dioxide generator 1 through the r...

Abstract

The invention discloses a device for automatic gas and liquid separation. The device comprises a high-purity chlorine dioxide generating device (1), a residue liquor storing tank (2), a residue liquor pump (3), a waste water treatment tank (4), a circulating pump (5) and a water ejector (6) which are sequentially connected in series. The high-purity chlorine dioxide generating device (1) comprises a chlorine dioxide generator (7), a buffering tank (8) and a special-shaped U-type pipe (9) which are sequentially connected. The invention further discloses a method for carrying out gas and liquid separation by adopting the device for the automatic gas and liquid separation. Chlorine dioxide gas can be efficiently separated, it is unnecessary to increase much investment, modifying can be carried out on the basis of an original generator, the requirement for water treatment and the requirements of customers can be met completely, and the device has great significance in water treatment, and solves the key problem for water treatment enterprises with the special requirements.

Description

technical field [0001] The invention relates to the technical field of inorganic chemical industry, in particular to a device for self-separation of gas and liquid and a method for self-separation of gas and liquid by using the device. Background technique [0002] Chlorine dioxide generators have been researched and developed in my country since the 1980s, and have a history of more than 20 years. They have been playing important roles in sterilization, disinfection, and decolorization in the field of water treatment. Since the date of research and development of the chlorine dioxide generator, the water ejector has been used to extract the prepared chlorine dioxide gas and the residual liquid after the reaction out of the generator, and send it to the treated water body for sterilization and disinfection. For this dosing method, the impact on water bodies without special requirements is not too great. However, for the treatment of tap water, secondary water supply, cyanide...
