Background
SF6The totally-enclosed combined electrical apparatus has small volume and excellent technical performance, and is an advanced high-voltage electrical distribution device which appears in the early 70 s, and is a Gas-insulator switch gear which is called GIS for short internationally. With the rapid growth of economic development in China, the electricity consumption of residents and industrial electricity are greatly increased, the construction speed of urban substations and enterprise substations is increased, and GIS electrical equipment is mostly adopted for construction of the substations in order to save land, purify the environment, ensure safe and reliable power supply. However, GIS equipment often results in equipment leaks and SF due to production quality and improper installation6The water content of the gas is higher. The leakage of the equipment can cause the density relay to send an alarm signal, even the low air pressure is locked to cause the failure to reject, and the failure range is enlarged. SF with higher water content6The gas is decomposed under high pressure to react with water to generate hydrofluoric acid which endangers the equipment when SF6If the moisture in the gas exceeds the allowable limit, the moisture condenses on the insulating surface when the temperature is lowered, so that the insulating strength is greatly reduced, and in severe cases, flashover is caused along the insulating surface, and internal failure develops. Once these failures occur, it is also difficult to rework and remove the defects without incurring economic loss. Therefore, the vacuum-pumping and air-charging for solving the above problems become one of the most important processes in the GIS installation process.
GIS equipment is inflated after needing evacuation when installation. When the vacuum pumping is performed, the exhaust hole of the rotary vane vacuum pump can exhaust oil smoke, and the environment is polluted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a smoke exhaust filter of vane rotary vacuum pump export installation for fully absorb the oil smoke in the vane rotary vacuum pump exhaust tail gas, make tail gas no longer the polluted environment.
The technical proposal of the utility model for solving the technical problem is that: the oil smoke in the tail gas discharged by the rotary vane vacuum pump is absorbed in a physical adsorption mode, and the oil smoke firstly passes through the oil mist filter core layer and then passes through the active carbon layer to be fully purified. The tail gas does not contain oil smoke and does not pollute the environment.
When the oil smoke absorbed in the filtering of the smoke exhaust filter reaches saturation, the filter element and the active carbon adsorption material in the smoke exhaust filter can be replaced.
Specifically, the utility model discloses take following technical scheme:
the utility model provides a smoke exhaust filter of spiral piece vacuum pump export installation, includes shell, oil mist filter core and active carbon filter core, is equipped with the inlet port on the lateral wall of shell, and the middle part of shell roof is equipped with the exhaust hole, and upper portion in the shell is equipped with the mounting panel that the level extends, and the top of oil mist filter core is fixed on the mounting panel, is equipped with columniform active carbon filter core in the middle part cavity that the oil mist filter core centers on.
Further, the active carbon filter element comprises a filter element frame, the filter element frame is of a net structure, active carbon particles are filled in the filter element frame, and the particle size of the active carbon particles is 2 micrometers.
Furthermore, the middle part of mounting panel is equipped with the round hole, is equipped with the epitaxial limit of horizontal direction on the top outer wall of filter core frame, and the filter core frame stretches into the oil mist filter core through the round hole and takes on the mounting panel through the epitaxial limit simultaneously.
