A disturbance device has two jet mixers, which are oppositely disposed in the horizontal direction; a mixing chamber, which is connected between the two jet mixers; and mixing pipes, which are connected below the mixing chamber. The mixing pipes comprise: a central pipe, which is a vertical straight pipe; multiple helical pipes, which are wound in multiple layers and provided outside the central pipe, the diameters of the multiple helical pipes gradually increasing from the inner to outer layers, and multiple flow deflector assemblies being provided at intervals in each helical pipe; and an outer sleeve, which is a straight pipe, the outer sleeve being sleeved outside the outermost helical pipe. A continuous gas separation system combines a hydrate-based process and a reverse osmosis process, using the disturbance device, enables continuous gas separation.

A differential-pressure sliding sleeve has an outer cylinder with a flow guiding hole being provided in a wall of the outer cylinder, an inner cylinder arranged in an inner cavity of the outer cylinder, an upper joint extending into the outer cylinder and fixedly connected to an upper end of the outer cylinder, a lower joint extending into the outer cylinder and fixedly connected to a lower end of the outer cylinder, and a dissolvable carrier ring arranged between the lower joint and the inner cylinder. An area of the axial upper end surface of the inner cylinder is greater than that of an axial lower end surface thereof, so that the working fluid generates a pressure difference to provide downward pressure for the inner cylinder, which moves downward under the pressure after the carrier ring is dissolved to open the flow guiding hole.
