Embodiment Construction

[0013] The principles and implementation methods of the present invention will be further described below in conjunction with the accompanying drawings.

[0014] figure 1 It is a schematic diagram of the oxygen concentration difference magneto-induced ventilation principle of the present invention, and is described in detail as follows:

[0015] A gas in a gradient magnetic field will be magnetized and will therefore be affected by a magnetic force as follows: f = 1 2 μ 0 x ▿ H 2 - - - - ( 1 )

[0016] Among them, μ 0 is the vacuum permeability (4π×10 -7 H / m), H is the magnetic field strength, and x is the magnetic susceptibility of the gas. For the mixed gas-air, its magnetic susceptibility satisfies:

[0017] x=∑y ...

Abstract

A magnetic ventilation method and apparatus based on the difference between oxygen concentrations for ambient air and the place needing ventilation is disclosed. The superconductive magnet is arranged between ambient air and said plate to generate a gradient magnetic field whose magnetic field force can drive air to flow in the pipe arranged in said magnetic field. Its advantages are saving energy, low noise and high effect.

Description

technical field [0001] The invention relates to a method and a device for generating ventilation between different oxygen concentration areas by using a high-gradient strong magnetic field, and belongs to the technical field of air conditioning and building ventilation. Background technique [0002] Ventilation plays an important role in improving the air environment in buildings, protecting people's health and improving labor productivity. In many industrial sectors, ventilation is an essential condition to ensure normal production and improve product quality. At present, the ventilation system in the prior art generally adopts a mechanically driven device (fan) to send the ambient air to the occasion requiring ventilation through the transportation pipe, so mechanical noise is bound to be generated. At the same time, there is no unified standard for controlling the fresh air volume. The average concentration of indoor carbon dioxide is usually used as an index to control...
