Abstract

A water vapor preparer comprises a system integration circulating pump, a heater, a throttling valve, a spray nozzle, a flash tank, a spray nozzle ejection and diffusion device. No electrical energy needs to be consumed. Waste heat is recycled for heating and water supplying in a cyclic mode, so that flash heat is provided. Water resources are saved, the electric charge for heating of a heat pump is reduced, and the investment is reduced. Secondary steam is produced continuously through cyclic heating, throttling, spraying and flashing. Hot compression of the secondary steam is achieved through overbottom pressure of a steam pipe network. The compression electric charge and the investment for a water vapor compressor are reduced. The pay back period can be ignored compared with the investment of water source heat pump heating and flashing and the investment of compression of the water vapor compressor. A steam multiplication function that n+1 parts of medium-pressure water vapor is prepared from one part of high-pressure water vapor is achieved.
