Embodiment 1
[0024] 1. Return the circulating water to the cooling tower pipeline to connect to the branch pipeline, and connect it to the inlet of the raw water pump as the water source for chemical water production. Control the opening of the circulating water isolation valve according to the temperature required by the water production equipment.
[0025] 2. Connect the circulating water tank and the outlet pipe of the original water tank to ensure that the liquid levels of the two tanks are balanced.
[0026] 3. Return the circulating water to the cooling tower pipe to connect to the branch pipe, connect to the circulating water tank, and control the water volume of the upper tower according to the temperature of the circulating water.
[0027] Such as figure 1 and figure 2 as shown, figure 1 It is the original flow chart, from which it can be seen that the water passing through the cooling equipment of the present invention can enter the water production equipment through the raw w...

The invention discloses a water-saving and energy-saving method for replacing circulating water with raw water in a thermal power plant. Tap water is pumped into a raw water tank and a circulating water tank, the water in the raw water tank is pumped into a water generating device through a raw water pump, and the water in the circulating water tank is pumped into a cooling device through a circulating water pump; the circulating water is made to pass through the cooling device, part of the circulating water is connected into an inlet of the raw water pump to serve as a chemical water generating water source, the opening degree of a circulating water isolation valve is controlled according to the temperature required by the water generating device, the other part of the circulating water is connected into the circulating water tank through a cooling tower, and the water amount of the cooling tower is controlled according to the temperature of the circulating water; the raw water tank is connected with a water outlet pipeline of the circulating water tank, the balance of the liquid levels of the two water tanks is ensured. According to the water-saving and energy-saving method for replacing the circulating water with the raw water in the thermal power plant, the traditional design of circulating water in the thermal power plant is changed, the traditional design of the circulating water is replaced with the design of raw water according to the unique process of the thermal power plant, the aims of saving water and energy and comprehensively utilizing resources are realized,and the economic performance of the thermal power plant is improved.
Description
technical field [0001] The invention relates to a water-saving and energy-saving method for replacing circulating water with raw water in a thermal power plant, and belongs to the technical field of energy saving and consumption reduction. Background technique [0002] At present, a circulating water system is designed in a thermal power plant to cool equipment that requires water cooling, such as generators, oil coolers, coal mill thin oil stations, air compressors, and fans. The circulating water with heat passes through the cooling tower, and the The heat in the water is dissipated into the atmosphere, and part of the high-quality water is also evaporated into the atmosphere, resulting in waste of water and heat energy resources. In the process of desalination in the chemical water workshop of thermal power plants, the raw water needs to be heated to a certain temperature to ensure the water production rate of the equipment. The equipment that needs equipment cooling and...
