Hydrodynamic cavitation heating device

Abstract

The invention provides a hydrodynamic cavitation heating device which comprises a stator, a rotor and a rotating shaft. A cavitation cavity is formed in the stator. A sealing cylinder body is adoptedas the rotor. The rotor is arranged in the cavitation cavity. The rotating shaft is installed in the stator and penetrates through the rotor in the stator. The rotor is fixedly connected with the rotating shaft. Cavitation holes are formed around the outer wall of the rotor and are blind holes. A water input pipeline is arranged at one end of the stator. A water output pipeline is arranged at theother end of the stator. According to the device, a motor drives the rotor to rotate at a high speed, the cavitation holes in the rotor and water move relatively, thus the cavitation phenomenon is caused, the purpose of heating water through the cavitation phenomenon is achieved, under the effect of a circulating water pump, hot water flows out of the hydrodynamic cavitation heating device and enters a heat exchanger through a water conveying pipeline, the hot water dissipates heat in the heat exchanger to achieve the heating effect, and the hot water flows back to a water storing tank througha circulating pipeline to prepare for heating circulation of the next time. The hydrodynamic cavitation heating device saves energy and is efficient, incrustation is not generated, pollution is avoided, energy consumption is low, and operation is safe and stable.

Description

technical field [0001] The invention relates to a device for heating and heating by generating thermal energy through hydraulic cavitation. Background technique [0002] Traditional heating is mainly divided into central heating and decentralized heating. Centralized heating is used for urban heating, mainly including large-scale gas, coal-fired, oil-fired boiler rooms and combined heat and power generation. These heating methods use fossil fuels to generate heat. The environment has had a great impact, exacerbating the smog weather; and a large amount of heat loss has been caused in the long-distance pipe network transportation. The thermal efficiency of traditional central heating with water as the medium can only be about 65%, and the heating efficiency is low, resulting in On the other hand, residents cannot control the heating temperature and heating time, which will cause heating waste when there is no one at home for a long time. [0003] Rural and remote areas most...
