8 results about "Airlift" patented technology

Various examples are provided related to airlift pumping of downhole geothermal fluids. In one example, an airlift system includes a compressor; a gas sparger head in a wellbore of a geothermal well, and a pressure head recycle assembly. The sparger head produces artificial lift of the geothermal fluids by injecting a gas resulting in a difference in density downhole. The entrained gas can be extracted by the pressure head recycle assembly, compressed, and reinjected downhole. The geothermal fluid at the well head can be used in direct use applications or in a thermodynamic cycle to make shaft power. The gas sparger head can include a venturi shaped passage extending through the gas sparger head and a bubble orifice including gas orifices radially spaced about a narrow portion of the venturi shaped passage. The gas orifices can have a corresponding resonant chamber through which the gas (e.g., air) is provided.

This application relates to the field of water propulsion and oxygenation, and discloses a large-scale airlift water propulsion and oxygenation device. In this application, an air intake body shell is welded to the upper surface of a high-pressure air pump. An air outlet plate is provided on the upper surface of the air intake body shell. A limiting frame is welded to the upper surface of the air intake body shell. An inner vertical ring is welded to the outer surface of the limiting frame. An outer vertical ring is movably inserted into the inner surface of the inner vertical ring. A balance plate is welded to the lower surface of the outer vertical ring. A nano-membrane tube is provided on the outer surface of the air intake body shell. The nano-membrane tube is connected to external air and provides airflow under the action of the high-pressure air pump, generating a pressure difference. Air is output through the middle and periphery of the air outlet plate, pushing open the outer vertical ring and the balance plate. Under the action of the inner and outer vertical rings, the outer vertical ring and the balance plate can only move up and down. When the pressure is uneven, the limiting action of the outer vertical ring and the balance plate compresses the air into other spaces, ensuring the uniformity and stability of the airflow.

This utility model discloses a propulsion aeration device based on the principle of airlift, relating to the field of wastewater treatment technology. It includes a floating plate, with an aeration mechanism on one side of the top of the floating plate. The aeration mechanism includes a fixed pipe connected to the floating plate. A sliding pipe is slidably connected to the inner wall of one end of the fixed pipe, and an air compressor is installed at the other end. In this utility model, through the arrangement of the aeration mechanism and the fixed mechanism, during use, the air compressor first starts, injecting gas into the lift pipe through the fixed pipe and the sliding pipe, causing the gas and liquid to mix and form a gas-liquid mixture. The density of the mixture decreases, and the less dense gas-liquid mixture moves upward under buoyancy, driving the surrounding liquid to flow, forming a circulation or directional propulsion flow. Thus, under the action of gravity, the liquid is lifted and transported, and discharged through the flow equalization hole. This device can evenly distribute gas into the liquid, forming fine bubbles.

The present invention relates to the technical field of aerospace vehicles, and specifically discloses a modular multi-purpose aerial delivery and air transportation unmanned aerial vehicle and a usage method thereof. The unmanned aerial vehicle adopts a canard layout with a "gong"-shaped double fuselage, double wings and double vertical tails. The core of it is that the front wing adopts a modular design, and the total wing area and aerodynamic center of the whole aircraft can be flexibly adjusted by replacing different components to adapt to different loads; a hanging area is provided under the front and rear central wings between the double fuselages, and a hoisting point with a winch is configured, so that a variety of loads can be quickly hoisted from the ground and released in the air. Through the modular design and innovative hanging and loading method, the single platform of the present invention can flexibly perform various functions such as cargo transportation, equipment aerial delivery (such as prototypes, rockets), mission payload carrying (such as communication base stations), etc., significantly improving the multi-functional adaptability and mission cost-effectiveness of the platform, and at the same time having the advantages of simple loading process and low deployment requirements.
