Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy-saving equipment technology, specifically a pump that utilizes the pressure of waste to perform work. Background Technology
[0002] During the production process, a lot of pressurized waste gas is often generated. For example, in the chemical production process, large closed reaction tanks will generate a lot of waste gas during the reaction. Similarly, when seawater purification equipment is working, a large amount of pressurized waste seawater will be generated. The pressure of this waste seawater can reach 5 MPa. This pressurized wastewater is often discharged directly without being recycled, thus causing a lot of energy waste. Utility Model Content
[0003] To fully utilize this waste energy, the purpose of this utility model is to provide a pump that uses pressurized wastewater to perform work without electricity, including a water turbine. The inlet of the water turbine is connected to the pressurized wastewater tank through a pipe, and the outlet of the water turbine is connected to the unpressurized recovery tank through a pipe. The water turbine drives a fan to rotate. The air inlet of the fan is open to the atmosphere, and the air outlet of the fan is connected to the air inlet of a tee through a pipe. The water inlet of the tee is connected to an extraction pipe, and the outlet of the tee is connected to a gas-liquid separator.
[0004] The gas-liquid separator includes multiple vertically arranged gas-liquid separation pipes. The upper end of the gas-liquid separation pipe is connected to the air hood, and the lower end of the gas-liquid separation pipe is connected to the main water outlet pipe.
[0005] The air hood is connected to the exhaust fan via a pipe.
[0006] The water turbine and the wind turbine are coaxially mounted.
[0007] The gas-liquid separation pipes are arranged in parallel vertically.
[0008] The advantages of this invention are: it utilizes the pressure of wastewater to drive a water turbine, which in turn drives a fan, thereby drawing in air to form a high-pressure gas. This pressurized gas, through a three-way valve and the pressure difference created by Bernoulli's principle, performs work, thus forming a pump that is not electrically driven. Of course, the pressurized gas of this invention can also be applied to other applications, such as as an energy source for air compressors. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0010] The present invention will now be described in detail with reference to the accompanying drawings. As shown in the drawings, the present invention includes a water turbine 2. The water inlet of the water turbine is connected to the pressurized wastewater tank 1 through a pipe, and the water outlet of the water turbine is connected to the unpressurized recovery tank 6 through a pipe. The water turbine 2 drives the fan 3 to rotate. The air inlet 31 of the fan is connected to the atmosphere, and the air outlet of the fan is connected to the air inlet 41 of the tee 4 through a pipe. The water inlet of the tee is connected to the extraction pipe 42, and the outlet 43 of the tee is connected to the gas-liquid separator 5.
[0011] The gas-liquid separator 5 includes multiple vertically arranged gas-liquid separation pipes. The upper end 51 of the gas-liquid separation pipe is connected to the wind accumulator 53, and the lower end 52 of the gas-liquid separation pipe is connected to the main water outlet pipe 55.
[0012] To increase suction power, the air hood 53 is connected to the exhaust fan via a pipe.
[0013] A preferred technical solution is that the water turbine 2 and the wind turbine 3 are connected by the same shaft 7, forming a coaxial arrangement.
[0014] Furthermore, the preferred arrangement of the gas-liquid separation tubes is that they are arranged side by side in a vertical direction.
