Abstract

The invention relates to a thermal power plant cooling water circulation agent adding system. A water inlet of a water supply pump is communicated with a water outlet pipe opening of a cooling water pool through a water pumping pipe, a pH value sensor is arranged on the water pumping pipe, a water inlet of a first cooling tower is communicated with a cooling water outlet of a condenser through a water outlet pipe, the water outlet pipe is communicated with a sulfuric acid tank through an acid supplementing pipe, and the acid supplementing pipe is provided with an added acid metering pump; andthe water outlet pipe is communicated with an agent storage tank through an agent adding pipe, the agent adding pipe is provided with an added agent metering pump, the pH value sensor is connected with a controller through a signal line, and the controller is connected with the added acid metering pump and the added agent metering pump through control lines. According to the thermal power plant cooling water circulation agent adding system, the pH value of cooling water entering the condenser is detected through the pH value sensor, an agent is added into a cooling water circulation system under control of the controller according to the pH value, and automatic agent adding of the cooling water circulation system is achieved.

Description

Technical field: [0001] The invention belongs to the technical field of thermal power generation, and in particular relates to a cooling water circulation dosing system for a thermal power plant. Background technique: [0002] In the process of thermal power generation, the steam that has been worked by the steam turbine is passed into the condenser, and the cooling water in the condenser cools the steam into condensed water for recycling. During this process, the cooling water absorbs heat and heats up. In order to recycle the cooling water, a cooling water circulation system is set up. The cooling water circulation system is an important part of the thermal power plant. It cools down the heated cooling water again and then recycles it. However, in order to prevent problems such as fouling in the condenser, the condenser has high requirements on the quality of cooling water. At present, in order to ensure the quality of cooling water, technicians add water quality stabilize...
