Description

Technical Field

[0001] This utility model relates to the field of water reuse, and in particular to a water-vapor sampling and water mixing device for power plants. Background Technology

[0002] This project aims to study how to recover water samples from steam-water sampling devices in power plants and return them to the condenser, instead of discharging them to wastewater treatment equipment as is the conventional design. This will achieve the goal of water resource recycling and reuse, reduce enterprise costs, lower overall plant water consumption, and achieve energy conservation and environmental protection.

[0003] The water sample from the steam and water sampling device is recycled to the condenser hot water well and implemented according to the principle of classified utilization. The drainage from the online silicon meter and online sodium meter is led out separately and directly enters the industrial wastewater treatment in the original way. At the same time, a water sample recovery device is used to collect the manual sampling of the remaining water samples and the drainage from the online instruments into the water sample recovery tank. After recovery, the water quality is re-neutralized, and the neutralized water enters the circulating water distribution system for direct recycling. Therefore, a mixing device that can simultaneously neutralize multiple tanks is needed. Utility Model Content
