Abstract

The invention provides a natural gas filtering device and a using and disassembling method of the natural gas filtering device. The natural gas filtering device comprises a filter barrel body, wherein a filter core is fixed in the filter barrel body by a filter core fixing device, the filter core comprises a filter core bottom plate and a filter core body arranged at the upper side of the filter core bottom plate, the filter core fixing device comprises a fixed screw rod and an anchorage pipe sheathed outside the fixed screw rod, the lower end of the fixed screw rod is fixedly connected with a supporting plate fixed in the filter barrel body, the upper end of the fixed screw rod is connected with a locking nut, the locking nut is pressed at the upper end of the anchorage pipe, the lower end of the anchorage pipe is pressed on the filter core bottom plate, and the filter core bottom plate is pressed on the supporting plate by the locking nut through the anchorage pipe and the fixed screw rod. The natural gas filtering device has a compact structure and good sealing property, and the filter core can be disassembled conveniently and can be fixed easily.

Description

technical field [0001] The invention relates to a filtering device for natural gas solid fine particles with a special structure, in particular to a gas turbine gas fuel system filtering device used in the natural gas power generation industry. Background technique [0002] The development and utilization of natural gas provides abundant and clean energy for people's life and production. In the gas turbine power generation industry using natural gas as fuel, natural gas is transported from upstream pipelines to gas turbine power plants, and impurities in natural gas entering the gas turbine will cause damage to key equipment of the gas turbine, such as control valves, fuel nozzles and flame tubes, seriously affecting the gas turbine power plant normal production. Therefore, before the natural gas enters the gas turbine, it is necessary to install a natural gas filter device as the last filter protection barrier for the natural gas to enter the gas turbine body for combustio...
