Water vapor phase change energy-saving apparatus

Abstract

The invention provides a water vapor phase change energy-saving apparatus capable of reducing vaporization potential heat value under power station boiler and industrial boiler water supply system. The energy-saving apparatus comprises a water inlet, a water outlet, a shell, a magnetization unit and a magnetization unit fixing device; the magnetization unit has multiple groups which are fixed by the magnetization unit fixing device and tightly arranged along the axial direction of a water-supply-pipe; the magnetization unit and the magnetization unit fixing device occupy the pipe space besides the water inlet and the water outlet; the magnetization unit comprises multiple groups of paired rare earth permanent magnets; and the any adjacent two groups of magnetization units are fixed on the pipeline cross section with wide angle of rotation angle.

Description

technical field [0001] The invention relates to a water treatment energy-saving device, in particular to a water-vapor phase-change energy-saving device suitable for use in power plant boilers and industrial boiler water supply systems for reducing the latent heat value of vaporization. Background technique [0002] In the furnace process of power plant boilers and industrial boilers, fuel combustion releases chemical energy. Through conduction, radiation and convection, the water working medium in various heating surfaces of the boiler is heated to the desired temperature, and the temperature rises and vaporizes into Saturated steam and superheated steam. For power plant boilers, the evaporated water vapor of the boiler is supplied to the steam turbine to do work, and the work capacity depends on the difference in the enthalpy value of the steam absorbed and discharged by the steam turbine. [0003] In various boilers, the evaporation rate of water refers to the speed at w...
