Abstract

The application discloses a device for eliminating the static pressure of downward flowing liquid, comprising : a riser pipe, the upper end of the riser pipe being connected with a first pipe for transporting fluid with a high static pressure, and the lower end of the riser pipe being connected with a second pipe for transporting fluid with a low static pressure ; and flow guiding means provided in the upstream section of the riser pipe and extending in the axial direction of the riser pipe. A fluid passage is formed between the flow guiding means and the inner wall of the riser pipe, the fluid passage comprises a spiral passageway to guide the high-static-pressure fluid coming from the first pipe and make it take the form of quasi-annular flow or annular flow. The static pressure eliminating device further comprises air compensating means, the air compensating means is communicated with the section of the riser pipe where annular flow is formed to maintain stable annular flow. With the static pressure eliminating device of the invention, the condition for forming annular flow in the riser pipe is improved, the dynamic enclose of the air in the riser pipe is realized. Air is prevented from mingling with the working water flow coming out of the riser pipe, and other harmful effects of the air are also avoided. It is possible eliminate the oxygen-etch problem and the air lock problem of the system and ensure the operation safety of the system. This device of the invention is simple in structure and has no moving components, thus having the same operation life as the system itself.
