Abstract

The invention relates to a large coal bed gas recovering complete device, which comprises a driving machine set, a compression machine set, a heat radiating blower, a gas and liquid separator, a filter and a lubricating oil pump which are fixed on an integrally-horizontal installation machine base with jointed planes. The jointed planes are all parallel to output shafts thereof and vertical to the self gravity thereof. A lubricating oil tank is arranged in the machine base and formed between the rectangular cross sections of the machine base. The gas and liquid separator is provided with a tangential gas and liquid inlet pipe and a vertical outlet pipe provided with a perpendicular downward rotational flow separating device. The installation bottom surface of the machine base is placed on an independent concrete foundation provided with an adjusting sizing block, and the concrete foundation and the ground on the periphery of the concrete foundation are provided with a shock prevention channel. The device has the advantages of good operation reliability and safety, lower chatter and noise during operation and long service life. A skid-mounted assembling and connecting structure is convenient for assembly and maintenance, and the device is particularly suitable for a large or large power coal bed gas recovering system.
