DIRECTIONAL CONTROL VALVE, AIR COMPRESSION SUBSYSTEM, AND INTEGRATED WATER UTILIZATION SYSTEM

摘要

An integrated water utilization system, related to the technical field of water purification. The integrated water utilization system comprises a water drawing subsystem, a water treatment subsystem, an air compression subsystem, a clean water preparation subsystem, and an air power generation subsystem. The water drawing subsystem utilizes compressed air to draw water from a water source and supplies the water to the water treatment subsystem. The water treatment subsystem heats the water to acquire concentrated water and steam. The air compression subsystem utilizes the steam to compress air and stores same. The clean water preparation subsystem is for use in condensing the steam into water and in preparing same into clean water that meets a discharge standard. The gas power generation subsystem utilizes the stored compressed air for power generation.
