The invention discloses a bubble removing device,
system and method.The bubble removing device comprises a shell with a containing cavity and a rectification structure, a liquid outlet is formed in the lower portion of the shell, a degassing opening is formed in the top wall of the shell, and the rectification structure is arranged on the bottom wall of the shell and comprises at least two rectification pipes fixedly connected together; the
pipe diameters of the at least two rectifying pipes are sequentially reduced from bottom to top to form a step
pipe, a bottom opening of the rectifying structure is a liquid inlet, a top opening of the rectifying structure is located below the degassing opening, and a gas escape area is formed in an area between the top opening of the rectifying structure and the degassing opening. The rectifying structure is of a step structure with a large lower part and a small upper part, the large-
diameter end of the rectifying structure is a liquid inlet, bubbles are randomly distributed when gas-liquid mixed fluid enters the rectifying pipes with larger diameters according to the laminar flow characteristic of the fluid, and when the gas-liquid mixed fluid enters the second rectifying
pipe, the bubbles are changed into a linear
queue from a dispersed state and are separated from a degassing port after passing through a gas escape area; the separation effect is good, the cost is low, the factory cost of biochemical analysis instruments is reduced, and the market competitiveness is improved.
