METHOD OF AND DEVICE FOR PREPARATION OF GAS

gas cleaning processes; gas-cleaning systems; cleaning natural gas before delivery to gas-distributing stations. SUBSTANCE: proposed method includes automatic removal of admixtures entrapped by filter to receiver; device used for realization of this method has filter and pipe line whose inlet is connected to lower portion of filter and outlet is connected to receiver. Innovation of invention consists in continuous removal of admixture into receiver with the aid of part of gas supplied from filter together with admixture into pipe line under pressure built up by exhaust ejector fitted at filter inlet; consumption of recirculating gas shall be no less than 5% of total consumption of gas to be cleaned; degree of compression created by ejector shall be sufficient for overcoming resistance of circulating trajectory including filter, pipe line, receiver and ejector. EFFECT: enhanced reliability; increased service life of gas-cleaning system; reduced power requirements; enhanced ecological parameters. 3 cl, 3 dwg
