Referring to fig. 1-6, the invention provides a geothermal water gas-liquid-solid separation device, and referring to fig. 1, the whole set of device and system consists of a geothermal water gas-liquid-solid separation device I and a water suction pump II, wherein the water suction pump II is used for sucking geothermal water treated by the geothermal water gas-liquid-solid separation device I, so that the geothermal water gas-liquid-solid separation device I can continuously and stably work;
referring to fig. 1 and 2, the operating frequency of the water suction pump II is controlled by a signal of a pressure difference type liquid level meter 5 on the geothermal water vapor liquid solid separation device I to maintain the liquid level in a tank body of the geothermal water vapor solid separation device I between a water permeable baffle 1-2 and a water impermeable baffle 2-3, so that the tank is always in a low pressure state;
referring to fig. 2, the geothermal water vapor-liquid-solid separation device I is divided into three cavities of an upper gas collecting cavity 1, a middle gas collecting cavity 2 and a bottom sand settling cavity 3 by a water permeable baffle plate 1-2 and a water impermeable baffle plate 2-3, and a hydrocyclone 4 is arranged in and penetrates through the three cavities;
referring to fig. 2 and 4, the hydrocyclone 4 is provided with an overflow port 4-2, a underflow port 4-3 and a feed port 4-1. The feed inlet 4-1 is connected with the liquid inlet 2-1 on the geothermal water gas-liquid-solid separation device I through a pipeline.
Referring to FIG. 5, the water permeable baffle 1-2 is composed of a punching plate 1-2A, a gas-liquid separation filler 1-2B and a grid plate 1-2C from top to bottom in sequence; the water permeable baffle plate 1-2 is provided with two water outlet openings 1-2D, and an overflow port 4-2 of the hydrocyclone 4 passes through the openings. Geothermal water-gas-liquid mixing during operation;
referring to fig. 2 and 6, the watertight barrier 2-3 can isolate geothermal water containing gas and water from entering the bottom sand settling chamber 3 through the watertight barrier 2-3. The watertight baffle 2-3 is provided with two mounting holes 2-3A for fixedly mounting the hydrocyclone 4 and enabling the bottom flow port 4-3 of the hydrocyclone 4 to pass through the watertight baffle 2-3, and the mounting contact part of the mounting holes 2-3A and the hydrocyclone is required to be provided with a seal.
Referring to fig. 1 and 2, geothermal water firstly enters a feed inlet 4-1 of a hydrocyclone 4 from a feed inlet 2-1 on a tank body of a geothermal water gas-liquid-solid separation device I, and as the whole tank body is always in a low-pressure state in the operation process, the cyclone effect of the hydrocyclone 4 can be exerted to the maximum extent, the gas-containing and solid-containing geothermal water can form strong cyclone along the inner wall of the hydrocyclone 4 under the action of the hydrocyclone 4, so that the geothermal water generates centrifugal force and different pressure distributions, and solid-phase particles such as sand grains, rust and the like are dragged to the closest inner wall position of the hydrocyclone 4 to be discharged into a bottom sand settling cavity 3 from a cyclone bottom flow port 4-3 under the double action of centrifugal force and gravity.
