Embodiment Construction

[0008] The present invention adopts a new generation method of differential pressure water level which is different from the traditional water pumping system, that is, the pressure oscillation generated by the thermoacoustic effect is used to cause periodic changes of the water level. Among them, the driving source of the thermoacoustic system is solar energy, and the solar energy collection device is used to improve the energy grade, and the temperature of the heat source is increased to above the vibration temperature of the thermoacoustic system. An amplifying device is connected to the resonant tube to amplify the periodical water level variation range caused by the pressure oscillation, thereby achieving the requirement of increasing the pumping height. In addition, in order to overcome the backflow phenomenon caused by the symmetry of the oscillation, a one-way valve device should be installed at the water supply end of the resonance tube, so that the water flow is only o...

Abstract

This invention discloses a hot voice pumping system of drive source is solar energy ad its pumping method. The system includes solar energy collector, resonatron, hot voice board, cold end hot exchanger, hot end hot exchanger, water level oscillation amplitude value amplifier, water charging system and high and low position pool. Pressure oscillation is generated by hot making voice effect by driving source is solar energy. Little amplitude water level oscillation generated by hot voice effect is amplified to a large amplitude water level oscillation through a slender coil pipe to elevate water from low water level to high water level. The intension of this invention is to use the regenerable energy solar energy (other residual heat and waste heat also) to drive a hot making voice conversion system, so the function of pumping water can be realized in place lacking electric power (for example field) to reach the goal of irrigation.

Description

technical field [0001] The invention relates to a thermoacoustic water pumping system and a water pumping method using solar energy as a driving source. Background technique [0002] The thermoacoustic effect is the mutual conversion process between heat and sound. According to the direction of energy conversion, it can be divided into two types: thermoacoustic and acoustic heating (cold). Since the sound wave itself is a kind of mechanical wave, it can generate periodic reciprocating motion near the equilibrium position. Thermosonic water pumping uses the thermoacoustic effect to generate sound waves. When it is at a low position, water is sucked into the system, and when it is moved to a higher position, water is discharged, so that after a cycle, a certain amount of water will be pumped from the low water level to the high water level, which forms a time-averaged water flow. Since the thermoacoustic water pumping effect first relies on the existence of pressure oscillati...
