Abstract: Disclosed is a gas treatment device that can efficiently regulate the temperature of a gas without being affected by load.

Abstract: Gas treatment equipment includes a compressor which compresses process gas, a first process module which is disposed downstream of the compressor and which treats the process gas, an expander which is disposed downstream of the first process module and which expands the process gas to obtain power, a second process module which is disposed downstream of the expander and which treats the process gas, and a driver which drives the compressor. A first pressure indicator is disposed at an inlet of the compressor for the process gas and measures a pressure of the process gas, and a second pressure indicator is disposed at an outlet of the second process module for the process gas and measures a pressure of the process gas. A recirculation flow path is connected to both of the outlet of the second process module for the process gas and the inlet of the compressor.

Abstract: An ozone generation system comprises an electricity charge unit price storing part which stores an electricity charge unit and a gas charge unit price storing part which stores a gas charge unit price, based on the electricity charge unit price, the gas charge unit price and necessary generation amount of ozone which is required for an ozonized gas, regarding an ozone concentration and a gas flow rate which are ozone generation amount basic parameters, values at which a running cost is a minimum are determined, a gas flow rate controller is controlled so as for a gas flow rate to be the determined gas flow rate and power of a power supply for an ozone generator is controlled so as for an ozone concentration to be the determined ozone concentration.

Abstract: An ozone generating apparatus having high reliability in which a glass tube can prevent from being damaged by melting a power feeding brush even if a large amount of short-circuit current flows. In an ozone generating apparatus using silent discharge, an alternating high voltage power is supplied from a power supply to a metal film formed in an inner wall of a glass tube by a power feeding brush comprising a brush shaft made of metal and a large number of metal thin wires fixed to the periphery of the brush shaft, the following equation satisfies. (D2/D1)?1/{1+(1/20?)}, wherein ‘D1’ indicates an outer diameter of a bundle of metal thin wires, ‘D2’ indicates an outer diameter of the brush shaft and ‘?’ indicates the line density of metal thin wires on a surface of the brush shaft.

Abstract: Disclosed is a gas processing apparatus which can be operated independently of the feed flow rate of a process gas.

Abstract: The heat transfer performance of a gas cooler provided with a fin tube type heat exchanger is improved. This is a gas cooler 10 which is provided with a heat exchanger 6, cools a gas to be cooled, which is introduced from the outside, by performing heat exchange between the gas to be cooled and the heat exchanger 6, and discharge the cooled gas to the outside. The heat exchanger 6 includes: a plurality of heat transfer fins 8 which are placed side by side via a prescribed gap therebetween, the gas to be cooled flowing through the gap; and heat transfer tubes 7 which pierce through the plurality of heat transfer fins 8 and are provided in a plurality of rows along the direction in which the gas to be cooled flows. The outside diameter do of the heat transfer tubes 7 is 20 to 30 mm.

Abstract: An apparatus for replenishing paint into a paint cartridge (25), which is capable of putting paint in respiratory circulation while the cartridge is in a waiting state. The apparatus includes a replenishing valve (61) which is capable of feeding paint to and from a paint chamber (30) of the paint cartridge (25) which is set on a replenishing stool (52), and a respiratory paint circulation valve (91) which is capable of feeding paint-extruding thinner to and from a thinner chamber (31) of the cartridge. After switching the replenishing valve (61) to a drain or discharge side, paint-extruding thinner is supplied from the respiratory paint circulation valve (91) to push paint out of the paint chamber (30) of the cartridge (25). Then, after switching the replenishing valve (61) to the side of a paint supply source, paint-extruding thinner is discharged by way of the respiratory paint circulation valve (91) to suck paint into the paint chamber (30).
