Abstract
The present invention relates to the UTILIZATION OF VESIDUAL HEAT IN of thermal power plant, realized the cooperation of power plant and waterworks, have remarkable social benefit and economic benefit.The solution of the present invention, thermal power plant need not build cooling tower, and the waterworks can provide hot water to the user, saves the energy.Make things convenient for the tap water user, reduce investment outlay simultaneously.
Description
The present invention relates to the UTILIZATION OF VESIDUAL HEAT IN of thermal power plant.
Cooling system of thermal power plant of the prior art is: the cooling water in the surface condenser is from cooling tower, after in condenser, carrying out heat exchange with the exhaust steam of steam turbine, exhaust steam is condensed into water, cooling water temperature raises simultaneously, returns in the cooling tower and cools off, in cooling procedure, cooling water after some heat absorption can evaporate, therefore, need often to give the cooling tower moisturizing, cooled cooling water injects condenser by circulating water pump again.
As shown in Figure 1, be thermal power plant of the prior art operating scheme, among the figure: 1 is boiler, and 2 is steam turbine, and 3 is condenser, and 4 is condensate pump, and 5 is cooling tower, and 6 is circulating water pump.
The defective of prior art is, needs the cost great amount of investment to build cooling tower, wants the water after the supply purification in the cooling tower running, therefore, no matter, all will consume a large amount of energy from direct and indirect angle.
The object of the present invention is to provide a kind of cooling system of thermal power plant, overcome the defective of prior art, reach purpose of energy saving.
The objective of the invention is to realize by following technological scheme:
Water after the purification of waterworks is introduced power plant's surface condenser, in condenser, carry out heat exchange from the water of waterworks and exhaust steam in steam turbine after, directly lead to the tap water user or return the waterworks.
Describe the present invention in detail below in conjunction with accompanying drawing 2.
As shown in Figure 2,1 is boiler among the figure, and 2 is steam turbine, and 3 is condenser, and 4 is condensate pump, and 6 is circulating water pump, and 7 is the waterworks, and 8 is the user.
Because the present invention does not do any change to the circulation of boiler → steam turbine → condenser → condensate pump → boiler, and the temperature that the water of condenser is transported in the waterworks can not be higher than the water temperature of transporting to condenser from cooling tower, so the present invention can not produce any harmful effect to the power generation performance of power plant.
Because the present invention has replaced cooling tower with the waterworks, so, saved the great amount of investment of building cooling tower, saved investment such as water purification and make-up water in the cooling tower, so have remarkable social benefit.
The present invention also can be the tap water user hot water is provided, and has made things convenient for user's life, save the energy, and has overcome water supply pipe is easy to cold cracking in winter defective.
The present invention also can be connected in series the condensed in two stages device, as shown in Figure 3, at this moment, both can improve the water temperature of supplying with the tap water user, and can not influencing to the user when a compressor emergency shutdown again provides hot water.
The water supply capacity of waterworks needn't be complementary with the water consumption of condenser among the present invention, as long as be not less than the consumption of condenser.
The present invention is particularly useful for the water shortage in north china area.
From the above, the present invention has overcome the prior art defective, has reached purpose of energy saving.
Claims (2)
