At least one layer of gauge filer 15 disposed in the tank 1 above the liquid level. An outlet 7 is provided near top end of the tank 1 for facilitating exit of the clean exhaust from the device.

An exhaust gas purification device of an internal combustion engine. The device comprises a cylindrical container where the exhaust gas is separated from the water vapor and purified from solid suspensions, and a cell where the purified exhaust gas is converted into oxygen once it has been disassociated by bombarding with ultraviolet rays. The oxygen thus recovered can be re-introduced into the atmosphere or reused for the combustion process.

A complex malodor removing equipment includes: a neutralizing module which dissolves a portion of malodor-causing substances, in malodorous gas introduced from malodor-producing equipment, in liquid water and removes same, which includes an acidity neutralizing module that introduces an alkaline substance from outside and removes an acidic malodor-causing substance from the malodor-causing substances, and an alkaline neutralizing module that introduces an acidic substance from outside and removes an alkaline malodor-causing substance from the malodor-causing substances, and which connects the acidity neutralizing module and the alkaline neutralizing module; and a balancing module which dissolves the remainder of the malodor-causing substances, in the malodorous gas introduced from the neutralizing module, in water and removes same, which includes an oxidation balancing module that introduces an oxidizing agent from outside and balances the malodor-causing substances, and a reduction balancing module that introduces a reducing agent from outside and balances the malodor-causing substances.

The present invention relates to a process and contactor vessel in which gas and liquid contact occurs to facilitate mass transfer therebetween. In one embodiment, the process includes a fluidised bed including mobile inert primary objects and secondary particles that facilitate turbulent mixing and enhanced gas/liquid surface area in the contactor.

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.

A biosensor and virusometer allows continuous, real-time detection of viral particles of pathogens, especially SARS-COV-2, both in indoor and outdoor air and in liquid samples in which the pathogen(s) have been collected. The biosensor includes a quartz crystal microbalance coated with a layer having one or more antibodies specific to one or more pathogens to be detected. A first virusometer is described, including an aerosol collector, which makes it possible to increase the concentration of pathogens before taking them to the biosensor. A second virusometer has a receptacle, divided into a first cavity wherein air exhaled by a user is collected and concentrated, and a second cavity wherein the biosensor is arranged.

A novel methodology of air purification and apparatus uses thorough air-bath to trap airborne debris and gaseous molecules in the liquid. Incoming air are crushed repeatedly and thoroughly at various stages into tiny air bubbles in contact with liquid in the apparatus where airborne materials and gaseous molecules are trapped in the liquid. This novel cleaning system can effectively remove small or large airborne debris and gaseous molecules, in contrast to cleaning effectiveness limited by the filter pore sizes in traditional filter system. The liquid can be water, water mixed with any designed substances or other type of liquid phase of materials. In exemplary case, water is used as a part of filtration medium, the apparatus thus can be served as both air purifier and humidifier. A relatively high humidity in the air would help to trap more airborne debris, which makes the air purification apparatus more efficient.

A system including a quench system that may cool a syngas generated in a gasification chamber. The quench system includes a quench chamber, a dip tube that may direct the syngas from the gasification chamber into a quench liquid in the quench chamber to cool the syngas and to generate a first cooled syngas, and a draft tube disposed circumferentially about the dip tube and configured to receive the first cooled syngas in a first direction along a first passage. The first passage is disposed between a first wall of the dip tube and a second wall of the draft tube.
