Description
Technical field
The present invention relates to a kind of circulating water discharge system, especially a kind of thermoelectricity for being conducive to environmental protection, reducing cost
Factory's recirculated water Zero discharging system.
Background technology
In recent years, with water pollution getting worse, water shortage is also more and more common.Thermal power plant is to use water rich and influential family,
Water consumption accounts for about 40% of industrial water or more.For this purpose, the various energy-saving and environmental protection policies of country, to water consumption amount, displacement
And water quality has stringent index limitation.However, greatly all being damaged naturally because of evaporation and wind in heat-engine plant circulating water
It consumes, the salinity in water is caused gradually to be concentrated.Due to concentration brine be more than to a certain degree will to recirculated water circulate equipment,
Pipeline etc. causes the adverse effects such as corrosion and fouling, thus just needs to discharge the recirculated water of partial concentration, while supplementing
Fresh water, to maintain the salt content of circulation to stablize.The concentration cycles water being discharged such as without processing, will to soil and
Natural water pollutes, so being closed, filling even depth processing, time-consuming and laborious, cost is higher.
Invention content
The present invention be in order to solve the above-mentioned technical problem present in the prior art, provide it is a kind of be conducive to environmental protection, reduce at
This heat-engine plant circulating water Zero discharging system.
Technical solution of the invention is：A kind of heat-engine plant circulating water Zero discharging system is equipped with circulating water intake, and follows
Ring water inlet is connected to coagulative precipitation tank, and coagulative precipitation tank is connected by the first valve with coagulant storage tank, the coagulating sedimentation
The water out in pond is connected by multi-medium filtering device with ultrafiltration apparatus, and fungicide storage tank is equipped with, and the fungicide storage tank passes through
Second valve is connected between multi-medium filtering device and ultrafiltration apparatus, and the water out of ultrafiltration apparatus connects with reverse osmosis unit, instead
The concentrated water outlet of permeability apparatus connects with evaporated crystallization device, and the pure water outlet of reverse osmosis unit connects with circulation, institute
Evaporated crystallization device is stated by third valve to connect with steam discharge pipe.
The present invention can be precipitated extra salt using electrical power generation steam waste heat and recycle pure to the recirculated water online processing of concentration
Water reaches zero-emission（Be not discharged outwardly has any dysgenic water to environment, final to be only evaporated to as a vapor greatly
In gas）, conducive to environmental protection and reduce fresh water magnitude of recruitment.Meanwhile without expending additional energy, discharge costs is saved, have been evaporated
The salt of crystallization passes through proper treatment, also can be used as raw materials for production, further decreases operation cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific implementation mode
The heat-engine plant circulating water Zero discharging system of the present invention is as shown in Figure 1：Equipped with circulating water intake 1, with circulating water intake 1
What is connected has solidifying sedimentation basin 2, coagulative precipitation tank 2 to connect with coagulant storage tank 4 by the first valve 3, the water of coagulative precipitation tank 2
（Precipitate clarified solution）Outlet is connected by multi-medium filtering device 5 with ultrafiltration apparatus 6, and fungicide storage tank 7, fungicide storage tank are equipped with
7 are connected to by the second valve 8 between multi-medium filtering device 5 and ultrafiltration apparatus 6, the water out of ultrafiltration apparatus 6 and reverse osmosis dress
It sets 9 to connect, the concentrated water outlet of reverse osmosis unit 9 connects with evaporated crystallization device 10, the pure water outlet and cycle of reverse osmosis unit 9
Water system 11 connects, and evaporated crystallization device 10 passes through third valve 12 and steam discharge pipe 13（The working steam of generating set）Phase
It connects.
Manually-operated gate can be used in first valve 3, the second valve 8 and third valve 12, and the electromagnetism controlled by PLC also can be used
Valve.
The course of work：
Recirculated water in circulation 11 enters coagulative precipitation tank 2 from circulating water intake 1, the first valve 3 is opened, by coagulant
In coagulant injection coagulative precipitation tank 2 in storage tank 4, precipitation removes part solid-state suspended particulate with the help of coagulant, sinks
Shallow lake clarified solution enters in multi-medium filtering device 5, removes most of solid granulates, and filtering production water is controlled by the second valve 8 to be added
Fungicide in fungicide storage tank 7 goes to enter ultrafiltration apparatus 6 in water removal after microorganism, 0.001 ~ 0.02 μm of diameter of removal or more
Ingredient, ultrafiltration production water enter back into reverse osmosis unit 9, the concentrated water of generation enters in evaporated crystallization device 10, by discharge of steam
Pipe 13 is supplied to 10 thermal energy of evaporated crystallization device by third valve 12, make concentrated water evaporation, concentration, crystallization, evaporation condensed water and
The salt of precipitation is recycling.And the pure water of 95% or more salinity is removed, it may return in circulation, realize zero-emission.
