The apparatus for pre-treatmenting a gas without supplying power

摘要

This invention is contained in the water in order to remove moisture from the sample gas separation measurement can be measured in the sample gas and the water is separated and removed is performed only by the air supply without the power supply to the transfer process in order to measure the dry gas can be used in explosion proof areas for explosion-proof measures without significantly the total volume of the configuration and its accompanying become easier with less maintenance, reducing, the site in general as well as explosion-proof safe in this place, and other hazardous areas and can be used reliably to the provision of non-powered gas pretreatment unit that applies for the purpose of widening. This invention is to achieve the above object, when supplied with an air vortex cooler for generating cold air; To remove the moisture contained in the sample gas to be measured by the cool air generated in the vortex cooler, a water separation chamber to create a sample gas to be measured in the dry gas, moisture is removed; And, conveying the air being supplied to the sample gas measured by the water separation chamber, to feed a small amount of water is removed in the drying gas supplied to the instrument by the water separation chamber, moisture is removed in the water separation chamber and the sample gas to the eductor discharge the received air and supply the remaining rest is supplied to the meter and completing the drying gas Dry gas for transfer; including, water in the gas to be measured without removing the power supply to the meter, and it is possible to perform the feeding of the drying gas moisture is removed, is needed in the region to provide a non-powered gas explosion pre-treatment device characterized in that it becomes available without explosion-proof measure. ;
