The present invention is a blowout preventer including a large frustoconical funnel, made of metal or other material. The large end of the funnel is placed over a well pipe (or other pipe) through which oil (or gas or other fluid) is blowing out. The small end of the funnel is connected to a return pipe. A high pressure pipe with a smaller diameter is inserted into the well pipe. Air is pumped under high pressure through the high pressure pipe, separating the oil and forcing the oil that is not kept down in the well pipe by the pressure up through the return pipe. The Bernoulli effect keeps the funnel on the well pipe. A gasket at the top end of the channel prevents leaks. Channels and rotating blades near the top of the funnel accelerate the flow, reducing pressure and increasing the suction due to the Bernoulli effect. |
