Claim 2:
3. The three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields according to claim 1, wherein flange plates are provided at two ends of the uniform mixing pipe body of the microbubble uniform mixer; an inner pipe wall of the columnar uniform mixing pipe section of the uniform mixing pipe body is configured with variable-diameter revolution surfaces; a shaft shoulder is formed at a junction of adjacent variable-diameter revolution surfaces of the columnar uniform mixing pipe section to realize an axial positioning of the microbubble generation circular plates; a diameter of a first small end circular surface of a conical surface where an inner pipe wall of the conical gathering and transporting pipe section of the uniform mixing pipe body is located is equal to an inner diameter of the swirling pipe body, an inner diameter of the axial flow column pipe body and an inner diameter of the axial flow horizontal drainage pipe; and after the microbubble uniform mixed axial flow is momentarily buffered in a lumen of the columnar uniform mixing pipe section, the microbubble uniform mixed axial flow is subjected to continuous pressure adjustment by the conical gathering and transporting pipe section and is gathered and transported to the swirling pipe body; and
the microbubble generation circular plates of the microbubble uniform mixer adopt super duplex stainless steel plates with a same thickness; outer ring surfaces of the microbubble generation circular plates are in an interference fit with a cylindrical surface where the variable-diameter revolution surfaces of the columnar uniform mixing pipe section are located; the variable-diameter micropores in one plate of the microbubble generation circular plates and the variable-diameter micropores in another plate of the microbubble generation circular plates adjacent to the one plate are arranged in an staggered manner, the variable-diameter micropores of each microbubble generation circular plate are uniformly distributed in a circumferential direction of the microbubble generation circular plate; each of the variable-diameter micropores comprises a left conical runner, a right conical runner and one columnar runner in the axial direction of the uniform mixing pipe body, and a cone height of a conical surface where a left conical runner of the variable-diameter micropore is located is greater than a cone height of a conical surface where a right conical runner is located.
