DEVICE FOR PRODUCTION OF PURIFIED AND DEHUMIDIFIED COMPRESSED AIR ON TRANSPORT FACILITY

摘要

pneumatic engineering; system for preparation of compressed air on transport facilities. SUBSTANCE: proposed device includes compressor with drive; delivery pipe line of this compressor is provided with compressed air cooler, adsorber with vent valve and actuating mechanism, check valve and scavenging air line fitted with throttle valve; device is also provided with air receiver and compressor pressure regulator, electronic unit for control of adsorbent scavenging time; its inlet is connected with compressor pressure regulator and outlet is connected with vent valve actuating mechanism for control of amount of air used for regeneration of adsorbent and dehumidified compressed air per delivery cycle of compressor; it is provided with additional check valve fitted directly before adsorber for slow filling of adsorber with compressed air through throttle valve after scavenging adsorbent by pressure-reduced air and forming mode purification of compressed air. EFFECT: reduced consumption of air for regeneration of adsorbent at ensuring required degree of dehumidification of compressed air at various duty cycles. 2 cl, 1 dwg
