Abstract
The utility model discloses an anti-explosion positive draft device in an oil and gas environment. The anti-explosion positive draft device comprises a positive draft chamber. A clean water source, an air source device, an external power system and an earthing system are arranged outside of the positive draft chamber. An anti-explosion light, an anti-explosion switch, a combustible gas detector, an anti-explosion connection box, a laser Doppler velocimetry (LDV) system and particle image velocimetry (PIV) system testing unit platform and an LDV system and PIV system data processing unit platform are arranged inside the positive draft chamber. An emptying breather valve is arranged on the top of the positive draft chamber. The anti-explosion positive draft device in the oil and gas environment has the advantages of being simple in structure and movable, can be applied to construction of a permanent laboratory in a natural gas gathering and transportation station, can also be flexibly used for flow field characteristic research testing construction of natural gas pipelines and equipment in single well stations and other field environments through adoption of a container steel structure, and achieves the purpose of anti-explosion.
