The present invention provides a device for preparing gas solution and a method for improving gas solubility in liquid. The gas solution preparation device comprises a gas generator, a gas-liquid mixer, and a water tank. The gas generator generates the gas source. The gas-liquid mixer is connected to the gas generator. A water absorbing flow branch of gas-liquid mixer and a discharge flow branch of gas-liquid mixer are respectively connected to a location between the gas-liquid mixer and the water tank. The water absorbing flow branch of gas-liquid mixer and the discharge flow branch of gas-liquid mixer together form a flow loop of gas-liquid mixer. In this invention, the gas in the form of micro-nanometer diameter gas bubble is sufficiently mixed with water to allow the gas-liquid mixture to circulate through the flow loop of gas-liquid mixer in a predetermined time to fast form a supersaturated gas solution in the water tank, and the gas mass concentration of the supersaturated gas solution is much higher t
