Abstract

The invention relates to a wind energy heating device of an airfoil fan with a vertical shaft. When wind blows through blades of a wind turbine, the vertical shaft positioned at the circle center of the blades rotates, a centrifugal pump is driven by a transmission mechanism to rotate together with the vertical shaft, so that hydraulic oil is sucked in a pump cavity of the centrifugal pump to be stirred so as to generate heat, and simultaneously high-pressure oil is drained; and furthermore, a plurality of stages of throttling orifice plates are arranged in a circulating pipeline, when delivered to the any stage of throttling orifice plate, the hydraulic oil is jetted out at high speed via a plurality of pipelines with small apertures on the throttling orifice plate, and the hydraulic oil and low-speed oil remained at an outlet of the throttling orifice plate are impacted, collided and rubbed, so that heat is generated. The vertical shaft of the wind turbine drives the centrifugal pump to rotate, starting wind speed is low, the structure is simple, installation and maintenance are facilitated, and heating efficiency can be effectively increased.

Description

technical field

[0001] The invention relates to a wind energy heating device, in particular to a wind energy heating device of a vertical shaft airfoil fan. Background technique

[0002] With the rapid development of modern industry and economy, global energy consumption is increasing rapidly. Energy shortage has become one of the main obstacles to future economic development. Ensuring energy supply and avoiding energy crisis has become the national policy of all countries. As a clean renewable energy, wind energy will inevitably become one of the ideal alternative energy sources in the future. my country is rich in wind energy resources. It is estimated that the total reserve is 32.26×1011W and the actual exploitable amount is 2.53×1011W based on the wind energy resources at a height of 10m above the ground.

[0003] At present, the main methods of wind heating include liquid stirring type, hydraulic resistance type, compressed air type, solid friction type and other win...
