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.

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.

The impurity removal method removes impurities in an exhaust gas and includes forming a froth layer in a tank, by blowing the exhaust gas into an absorbing liquid contained in the tank via a gas dispersion pipe, wherein, given that a proportion of the gas occupying the froth layer is defined as a gas holdup, impurities such as soot dust included in a gas such as an exhaust gas is removed efficiently and at a low cost by setting a gas holdup in the froth layer to be 0.40.9, setting a height of the froth layer to be 0.21.8 m, and setting a gas-liquid contact area per unit volume of the froth layer to be 15002500 m.sup.2/m.sup.3.

Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney. Further disclosed is a method of adjusting a vapor split ratio using the vapor splitter.

The invention relates to a system for transferring mass with the capturing of solids via the induction of an electromagnetic field, comprising a plurality of cells formed in a plurality of discs forming an assembly of means for generating a membrane and electromagnetic field. The liquid membranes formed in this assembly collapse upon contact with a gaseous current. The collapsed liquid material covers the suspended particles and removes same via decanting, and the cells of the membrane also increase the speed of the gaseous current and cause same to impinge on the surface of the liquid, thereby improving the transferral of the vapour to the gas. The system also has means for generating an electromagnetic field that are electrically energised in order to provide an electromagnetic field to the assembly, such that the solids circulating after the rupture of the liquid membrane are attracted to each disc depending on the ionic behaviour thereof. The system also has means for capturing solids that are radially adjusted in the space between discs, and means for removing solids that are adjusted to the capturing means for removing or carrying the captured solids.

The present invention provides a dust removal system for a chimney of a mixer. The system includes a dust removal water tank and a first pipeline. One end of the first pipeline is communicated with an outlet of the chimney at a tail of the mixer, and the other end is inserted into the dust removal water tank. A water inlet and a water outlet are provided in the dust removal water tank. An exhaust port for discharging filtered gas is provided in an upper part of the dust removal water tank. The system does not need additional power, and is energy-saving and environmentally friendly. Water vapor discharged facilitates the sedimentation of dust particles in the mixer, thereby reducing loss of raw material mixture, making sintering quality more stable and solving a problem that gas discharged in prior arts contains more powder and pollutes the environment.

Provided herein is a portable air purifier. The portable air purifier includes: a body; first to third accommodation portions configured to have respective open top surfaces in order to separately accommodate a battery, an air compressor, and water; first to third covers configured to selectively open and close the respective open top surfaces of the first to third accommodation portions; an air inlet connected to the lower portion of the second accommodation portion, and configured to accommodate a pre-filter; a siphon pipe positioned upright inside the water of the third accommodation portion, and configured such that the top thereof is connected to the air outlet of the air compressor; a cannula installed on the top of the third accommodation portion, and configured to supply purified, humidified air to a user; and a power switch configured to control the amount of air to be supplied.

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicles, with or without using flow establishing devices.

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.

Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney.
