Each cell is pressurized with gas from outside of the cell, the amount of permeation of the gas permeated into each cell is measured, and a cell having the amount of permeation greater than (average value of all cells+A) (wherein A is a predetermined value of ? to 6?, where ? is the standard deviation) is considered to be defective. Alternatively, pressure is reduced for each cell, the degree of vacuum in each cell is measured, and a cell having the degree of vacuum worse than (average value of all cells+A) is considered to be defective. Then, a polymer compound is poured into the defective cells of the monolithic separation membrane structure and cured so that the defective cells are sealed. Alternatively, the polymer compound formed in advance as the sealing member is inserted into the defective cells to seal the defective cells.

A method is presented for collecting and removing radon from a confined area, a storage box or articles of clothing. The method includes collecting radon from the confined area or around a storage box via at least one collector, connecting each of a plurality of radon adsorbers to a corresponding power supply or power source such as a battery, capacitor, fuel cell, etc. diverting, via a plurality of valves, the collected radon or radon daughters through one or more of the plurality of radon adsorbers, and receiving, via a plurality of radon storage units, radon or radon daughters held by the plurality of radon adsorbers for a predetermined period of time.

A waste gas purification system includes a gas container, a gas input unit for intermittent entrance of waste gas into the gas container, a gas output unit for discharge of the waste gas out of the gas container after the waste gas is purified, and a contaminant capturing apparatus disposed in the gas container and including a capture device that purifies the waste gas by using an adhesive to adhere particulate matter in the waste gas. A length of an active time the gas input unit allows for entrance of the waste gas into the gas container does not exceed sixty seconds. A length of a pause time the gas input unit does not allow for entrance of the waste gas into the gas container does not exceed thirty minutes.

The aggregating device includes i) a conveying means selected from a group consisting of a conveyor belt, a liquid pressure, a liquid column and a liquid wave of the liquid material, a centrifugal force, a centripetal force, an injector, a venturi device, a diffuser, a ducted turbine, a delta wing concentrator, an annular venturi device, a magnus effect turbine, a passive and active convection, effusion and diffusion, for receiving and/or conveying an aerosol and/or a liquid material in the conveying direction into the aggregating device, ii) an exciter for generating an acoustic sound wave which impinges upon the aerosol and/or the liquid material, and iii) a means for separating condensed liquids and/or aggregated solid materials from the aerosol and/or the liquid material.

The present invention relates to a method for treatment of a hot gas generated by a pyrolysis or a gasification process, wherein the hot gas is passed to a first unit for particle removal and cooling, whereby subsequently, a gaseous stream is removed from a first condensed stream thus obtained and passed to a second unit for particle removal and cooling, wherein a second condensed stream is obtained, said first condensed stream and second condensed stream being recycled to said first unit and said second unit, respectively.

A neon recovering/purifying system including: a recovery vessel that is arranged on an exhaust gas route and stores exhaust gas, the exhaust gas route being branched and extending from a discharge line; a compressor that increases a pressure of the exhaust gas sent out from the recovery vessel, to a third pressure; an exhaust gas flow rate regulating unit that regulates a flow rate of the exhaust gas whose pressure has been increased by the compressor; a first impurity removing unit that removes a first impurity from the exhaust gas; a second impurity removing unit that removes a second impurity from the exhaust gas from which the first impurity has been removed; a pressure increasing vessel that stores purified gas that has been processed by the first impurity removing unit and the second impurity removing unit; a pressure reducing valve that reduces a pressure of the purified gas sent out from the pressure increasing vessel, to the first pressure; and a purified gas flow rate regulating unit that regulates a flow rate of the purified gas supplied to a supply line of a manufacturing system.

A multi-channel particle separator includes a plurality of vanes. Each vane is spaced apart from at least one other adjacent vane to define a flow channel, and includes a leading edge, a trailing edge, a first side wall, a second sidewall, and a splitter. The first side wall extends between the leading edge and the trailing edge. The second side wall is spaced apart from the first side wall and extends from the leading edge toward the trailing edge. The splitter may be rotationally coupled to the trailing edge and extend toward the leading edge. The splitter is spaced apart from the first side wall to define a scavenge volume and is rotatable between an extended position and a retracted position. The vanes may also or instead be coupled to a ring-shaped structure.
