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.

The present invention relates to an apparatus for gas-liquid contacting and gas distribution in a bubble contactor. More specifically, the present invention relates to a gas-liquid distribution device that may be used in an ionic liquid co-current gas and liquid up-flow regenerator designed to distribute gas uniformly across the regenerator cross section through restriction orifices on a distribution plate with liquid upcomers.

A filtration liquid tank (100) for a dedusting device and a dedusting device with the same are provided. The filtration liquid tank (100) includes a tank body (1) formed with an inlet and an outlet; a cyclone separator (3) disposed within the tank body (1) and in communication with the outlet, defining a cyclone separation chamber therein, and formed with a cyclone inlet (31) in communication with the cyclone separation chamber; and a water pressing assembly (2) disposed within the tank body (1) and in communication with the inlet, and configured to guide an airstream entering from the inlet towards a filtration medium and produce a circumferential motion, the airstream filtered by the filtration medium being exhausted from the outlet.

The present disclosure relates to an apparatus and method of removing pollutants from exhaust gas by wet scrubbing process. In a scrubber apparatus of the present disclosure, an exhaust gas is first scrubbed in a primary mixing zone, the partially scrubbed gas discharged from the primary mixing zone is subsequently mixed forcibly in a secondary mixing zone before being discharged for polishing, demisting and/or reheating.

Disclosed is a wet air purifier that eliminates contaminants while contaminated air passes therethrough by causing the contaminated air to come into contact with water. The wet air purifier suctions external air by rotating a rotary fan installed therein and disperses water droplets by causing water to collide with a rotary fan to increase a contact surface between air and water. In the wet air purifier, a mixture of the contaminated external air and the water is made to pass through a long narrow passage and guided to a storage tank in which contaminants are settled. In this way, the wet air purifier increases a retention time and a collision time of water and contaminated air. The wet air purifier also can function as a humidifier.

A liquid filter apparatus for gas/solid separation includes a housing with a filter chamber, a semiconductor process gas inlet, and a process gas outlet. The filter chamber forms a liquid reservoir, and the semiconductor process gas inlet and the process gas outlet are in communication with the filter chamber. The housing further includes a filter liquid inlet and a filter liquid outlet, which are in communication with the liquid reservoir for delivering and removing filter fluid, respectively, to and from the liquid reservoir.

A wet scrubber can be used to capture dust particulates from a bulk powder conveyed into a mixing system. The mixing system can be used to form a treatment fluid for use in an oil and gas operation, such as a cement slurry. The wet scrubber includes a first section having two sets of baffles that create a first and second stage. Air and the dust particulates flow into and through the baffles of the first stage and turbulently mixed with water in the wet scrubber to capture the dust particulates. The air and any remaining dust particulates then flow into and through the baffles of the second stage and turbulently mixed with the water. One or two additional sections, each having baffles, can be included to accommodate varying air flows into the scrubber. The baffles in the various sections can be lower in the water than other sections.
