Claim 0:
1. A natural gas separation and purification and mercury collection system for oil and gas wells, comprising a cyclone separator, a condensation purification and separation mechanism, pressure buffer mechanisms, mercury collection and separation mechanisms, natural gas storage tanks, and a driver circuit, wherein an inlet end of the cyclone separator is communicated with an external gas source through a first pressure buffer mechanism of the pressure buffer mechanisms, and an outlet end of the cyclone separator is communicated with the condensation purification and separation mechanism through a second pressure buffer mechanism of the pressure buffer mechanisms; the condensation purification and separation mechanism is communicated with the mercury collection and separation mechanism through a third pressure buffer mechanism of the pressure buffer mechanisms; the mercury collection and separation mechanism is communicated with the natural gas storage tank through a first guide tube; each of the cyclone separator, the condensation purification and separation mechanism, the pressure buffer mechanisms, the mercury collection and separation mechanisms, and the natural gas storage tanks is provided with a control valve; the cyclone separator, the condensation purification and separation mechanism, the pressure buffer mechanisms, the mercury collection and separation mechanisms, the natural gas storage tanks, and the control valve are electrically connected to the driver circuit; at least two mercury collection and separation mechanisms are connected in parallel to each other and communicated with the pressure buffer mechanisms and the natural gas storage tanks through a shunt.
