An ozone injector device comprising a housing, a corona tube disposed within the housing and configured to generate ozone, a check-valve removably coupled to the water passageway, a second end of the check-valve having a cavity with a movable float contained therein, an ozone inlet fitting removably coupled to the check-valve, the ozone inlet being in fluid communication with the corona tube via a corona discharge tube such that ozone entering the water passageway through the ozone inlet fitting must pass through the check valve, and a spring-loaded clearing piston positioned to move into and out of the water passageway, the clearing piston being biased upwards, and configured to prevent flow of ozone into the water passageway.

A gas compressor comprising a rotating drum and a return assembly. The drum includes a compression channel assembly with compression channels between a common zone and a distal area. The compression channels may be formed by a plurality of V-shaped blocks. The return assembly draws liquid from an annular lake formed in the drum to a fluid outlet. A gas inlet in the return assembly mixes incoming gas with the liquid. An optional eductor connected to the gas inlet draws gas into the gas inlet. Fluid entering the common pressure zone is forced into the compression channels that compress the gas. Pressurized gas is separated from liquid in the fluid prior to leaving the compression channel. An inducer may be positioned between the fluid outlet of the return assembly and the opening of the centralized common pressure zone.

Provided are a rotational flow generator, a piping system, a semiconductor manufacturing apparatus, and a heat exchanger that enable the clogging of a pipe member to be more effectively prevented. A rotational flow generator 1 comprises a spray port 14a that can be attached to/removed from a pipe member 103 through which a first fluid flows, and that sprays a second fluid in a direction inclined with respect to the center axis line of the pipe member 103. A rotational flow generated by the rotational flow generator 1 can reduce the amount of accretion on an inner wall of the pipe member 103.

An aspirator air vent valve may include an air vent valve body coupled with an aspirator body and a pipe fitting. The air vent valve body may include an air vent valve air channel defined by an inner wall of the air vent valve body and disposed between the aspirator body and the pipe fitting. The aspirator air vent valve may further include a vent passage defined by a first vent wall and a second vent wall and disposed between an outer wall and the inner wall of the air vent valve body, wherein the vent passage is in fluid communication with the air vent valve air channel. The aspirator air vent valve may further include a plunger coupled with the air vent valve body.

A pump for pumping a gas, the pump comprising: a rotor and a stator; the rotor comprising at least one liquid opening configured for fluid communication with a liquid source. The liquid opening is configured such that in response to a driving force a stream of liquid is output from the opening, the stream of liquid forming a liquid blade between the rotor and the stator, gas confined by the stator, the rotor and the liquid blade being driven through the pump along a pumping channel from a gas inlet towards a gas outlet in response to relative rotational motion of the rotor and the stator. A cross sectional area of the pumping channel is configured to increase from the gas inlet to the gas outlet.

A system for hybrid gas lifting may include a gas-lift completion arranged to inject high-pressure gas into production tubing of a well. The system may include a downhole annular jet pump. The downhole annular jet pump may include an annular nozzle arranged to receive the injected high-pressure gas. The injected high-pressure gas exits the annular nozzle as an annular high-velocity gas jet. The downhole annular jet pump may include a throat section arranged to receive the annular high-velocity gas jet, and to mix the annular high-velocity gas jet with a low-pressure production fluid. The downhole annular jet pump may include a diffuser section arranged to facilitate conversion of kinetic energy into pressure energy in a mixture of the annular high-velocity gas jet and the low-pressure production fluid, and to produce the mixture to a surface via the production tubing.
