specific Embodiment 1

[0032] refer to figure 1 , the fully digitalized self-balancing water system of the power plant water system monitoring involved in this embodiment includes a control system, a water supply system and a drainage system, and the water supply system and the drainage system are connected as one through the field bus technology control system to form a power plant water system; the water supply system There are two water intake channels for reservoir water intake and municipal tap water. The water outlet of the water supply system is connected to the water inlet of the domestic water system 1 and the industrial water system 2 in the power plant to form a water delivery network 3; the water inlet of the drainage system is connected to the domestic water system. 1 and the drainage end of the industrial water system 2 constitute a drainage pipe network; at all the water inlet ends of the domestic water system 1 and the industrial water system 2, a digital flow transmitter is installed...

specific Embodiment 2

[0040] refer to figure 2 , the characteristics of this embodiment are: the sewage of the domestic water 1 is transported to the domestic sewage treatment device 4 through the sewage pipe for treatment, and then transported to the industrial water pipe network. When in use, when the sewage of the domestic sewage treatment device is detected After treatment, when the storage of water for greening is saturated, the sewage discharge of the domestic sewage treatment device 4 is controlled through the control system of the water affairs center. If it is detected that the discharged sewage reaches the standard that can be directly supplied to industrial water, it is directly transported to the circulation of the industrial water 2 pipe network If it is detected that the water pipe cannot meet the industrial water standard, it will be transported to the industrial wastewater treatment system 5 for further treatment before use. All the other are with embodiment 1.

Abstract

The invention relates to a monitoring method for a power plant water system and a full-digitalized self-balance water affair system, wherein the method and the system are applicable to an industrial project with a waste water pollution discharge circulation and environment-friendly water utilization system, for example, a coal power plant in an industrial zone. The method includes the steps that first, a water utilization system comprising a control system, a water supply system and a water discharge system is established through a field bus technology, and water quantity balance instruments are arranged on water inlets and water outlets of all water utilization points of the water utilization system; second, the water quantity balance instruments are connected into the control system so as to monitor water inflow and discharge conditions in all places in real time, output data of the water quantity balance instruments are calculated in the control system so as to obtain water utilization volumes and water discharge volumes in all the places, and water inflow and utilization balance is achieved through control of the control system; third, intelligent equipment with field bus connectors are adopted for all kinds of transmitters and analysis instruments related to the power plant water utilization system, and thus full-digitalized real-time monitoring is achieved. The invention further discloses the self-balance water affair system for full-digitalized monitoring on water for power plants. The self-balance water affair system achieves water quantity self-balance and waste water zero discharge.

Description

technical field [0001] The invention relates to a fully digital monitoring method for power plant water use and a self-balancing water system, which is suitable for large-scale water use in coal power plants and various factories and enterprises in industrial areas and water system projects with waste water and sewage recycling for environmental protection. The invention belongs to the technical field of water resource integration utilization technology and power plant supporting equipment technology. Background technique [0002] With the increasing tension of global water resources, whether it is domestic water or industrial water, more and more attention is paid to water resource conservation. The control systems of the various factories or workshops of the general industrial water system are independent of each other, and each is responsible for the water inflow and treatment in the factory or workshop. After water treatment, part of the water obtained from nature is use...
