Apparatus and method for degassing and preventing gelation in a viscous liquid

摘要

An apparatus for degassing and preventing gelation in a viscous liquid stored in a reservoir tank is provided. For a viscous liquid such as one that has a viscosity higher than 5000 cp, a reservoir tank that has a cavity for holding the liquid is first provided which is equipped with a liquid feed conduit and a liquid output conduit. The liquid feed conduit is configured in J-shape with an inlet end at a top of a first vertical section in fluid communication with a liquid source tank and an outlet end at an opposite end of a second vertical section of the J-shape conduit protruding above a liquid level stored in the tank cavity. A U-section of the liquid feed conduit is generally immersed in the viscous liquid. A liquid output conduit of straight shape is further provided in the reservoir tank which has an inlet end immersed in the liquid at or near a bottom of the cavity and an outlet end in fluid communication with a dispensing nozzle of the liquid through the use of a pumping means.
