The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

A wastewater treatment device has: an ozone generator which supplies ozone; a mixer which mixes ozone supplied from the ozone generator with wastewater and supplies ozone mixed wastewater; an ozone oxidation unit which progresses ozone oxidation in the ozone mixed wastewater while passing the ozone mixed wastewater therethrough and discharges wastewater in which the ozone has been consumed; a biological treatment unit which performs biological treatment on the wastewater discharged from the ozone oxidation unit using microorganisms; and an adjusting device which adjusts the amount of ozone to be mixed with the wastewater by the mixer so that ozone in an amount that inhibits the microorganisms of the biological treatment unit does not remain in the wastewater discharged from the ozone oxidation unit.

The apparatus for measuring disentrainment rate of air includes a Confined Plunging Liquid Jet Reactor (CPLJR) having a downcomer column surrounding a liquid jet. The end of the downcomer column is partially immersed in a receiving liquid pool contained in a reservoir. A conical ring is placed in the downcomer column below the liquid jet, the ring bearing against the wall of the downcomer column and forming a seal to define a headspace in the column. A gas supply and first bubble meter are connected to the column above the conical ring to supply gas and measure total entrainment. A second bubble meter connected to the headspace between the ring and the receiving pool measures disentrainment, and a third bubble meter connected to headspace above the receiving pool outside the column measures net entrainment.

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.

The present application discloses a ozonated water delivery system which includes at least one contacting device in communication with at least one ultrapure water source configured to provide ultrapure water, at least one ultrapure water conduit coupled to the ultrapure water source, at least one solution in communication with the contacting device and the ultrapure water source via the ultrapure water conduit, one or more gas sources containing at least one gas in communication with at least one of the ultrapure water source, the ultrapure water conduit, and the solution conduit, at least one mixed gas conduit in communication with the at gas source and the contacting device and configured to provide at least one mixed gas to the contacting device, and at least one ozonated water output conduit may be in communication with the contacting device.

An apparatus comprises a separator, a compressor, a mixer and a pump. The separator operates on an input gas mixture comprising carbon dioxide gas and one or more other gases, providing a separated carbon dioxide gas output. A compressor compresses the separated carbon dioxide gas output, providing a second output comprising at least one of gaseous carbon dioxide and liquid carbon dioxide. A mixer mixes the second output with liquid water under pressure to provide a third output comprising: at least one of liquid carbon dioxide and gaseous carbon dioxide; and water with dissolved carbon dioxide. A pump pumps the third output into an underground structure such that components of the third output react with available rock surfaces to form stable carbonates.

The present disclosure includes a mixing device for use in a contact tower. The mixing device can include a first tray defining multiple first openings and multiple mixers coupled to the first tray. Each mixer can include a first portion having a first sidewall and a second portion extending from the first portion, the second portion having a second sidewall. The first sidewall can define an inlet in communication with one of the first openings, an outlet, a convergent channel extending between the inlet and the outlet of the first sidewall, and an injection port extending through the first sidewall and positioned between the inlet and outlet of the first sidewall. The second sidewall can define an inlet in communication with the outlet of the first sidewall, an outlet, and a divergent channel extending between the inlet and the outlet of the second sidewall.

The confined plunging liquid jet reactor with energy recovery includes a downcomer having an upper end, an open lower end, and a gas inlet for receiving gas, the downcomer extending into a liquid reservoir in a tank. A nozzle is mounted on the upper end of the downcomer for receiving a pressurized liquid to generate a liquid jet. The liquid jet impinges on liquid contained within the downcomer, creating turbulence and bubbles to entrain gas introduced through the gas inlet into the liquid reservoir as the jet travels downward in the downcomer. A riser is disposed around the downcomer and defines an annular air lift column. Unentrained gas and liquid exiting the downcomer rises in the air lift column with significant energy, the upper end of the riser being connected to a turbine coupled to a generator to recover energy from the air lift column.

An oily smoke purification device includes a holder, a main housing, a mixing mechanism, a filter and an exhaust fan. The holder is filled with purification solution, the exhaust fan is started to cause a negative pressure inside the main housing, oily smoke enters the purification solution from a gap between the holder and the main housing and is mixed with the purification solution under an action of the mixing mechanism to absorb dirt in the oily smoke into the purification solution, and the oily smoke is filtered by the filter to generate clean air which is sucked by the exhaust fan. The hazardous substance including oil, dust and other impurities in the contaminated air is filtered and the air is purified, thereby protecting the environments and ensuring the heath of people.
