Description

A kind of thermal power plant water temperature regulation device
Technical field
This utility model relates to water-treatment technology field, particularly relates to a kind of thermal power plant water temperature regulation device.
Background technology
In recent years, the utilization of recirculated water increasingly paying attention to by the especially coal-fired thermal power plant of power plant, main Recirculated water from the condensation water of condenser, and the draining of condenser needs could utilize, instead after reverse osmosis unit processes The inflow temperature of permeability apparatus typically requires, at 25 degree, the most not can exceed that 5 degree, when summer temp is higher, and the row of condenser Coolant-temperature gage is generally possible to meet this temperature range, but the temperature at discharging condensate of condenser in other is the most all less than 20 degree in season , it is impossible to being directly entered reverse osmosis unit and process, under conditions of some are extreme, the temperature at discharging condensate of condenser is also possible to surpass Crossing 30 degree, can not be directly entered reverse osmosis unit equally, current solution is a kind of is the cold water outside utilization or hot water Water source, this obviously do not meet recirculated water utilize requirement, another kind is to arrange thermostatic water tank, makes the temperature in water tank remain Between spending 20 to 30, but so will necessarily increase energy consumption, although achieve and recycle water and but add station-service electricity.
Utility model content
The technical problems to be solved in the utility model is to provide one can control water temperature, meets reverse osmosis unit water inlet and wants Ask, do not use external water source, the thermal power plant water temperature regulation device of energy efficient.
For solving above-mentioned technical problem, embodiment of the present utility model provides a kind of thermal power plant water temperature regulation device, Including condenser outlet pipeline, mixing tank, mixing tank is provided with mixing water outlet pipeline, described thermal power plant lower water temperature Device also includes heating water tank and controls device, and condenser outlet pipeline is respectively communicated with mixing tank and heating water tank, mixing water Case connection heating water tank, between condenser outlet pipeline and mixing tank and heating water tank, between mixing tank and heating water tank, It is equipped with flow valve on mixing water outlet pipeline, in heating water tank, is provided with electric heating tube, control device and include PLC, temperature Degree sensor, flow valve control circuit, temperature sensor quantity is 3, is separately positioned on inside mixing tank, in heating water tank Inside portion, condenser outlet pipeline.
Further, described heating water tank volume is the half of mixing tank.
Further, described heating water tank surface is additionally provided with display control panel, and described display control panel includes display Screen and rotary switch.
Further, described control device also includes showing control circuit.
Having the beneficial effect that of technique scheme of the present utility model:
In such scheme, control device, heating water tank, mixing tank, condenser water outlet by arranging heating water tank and PLC Mixed connection between pipeline, by heating a small amount of water, so that it may so that mixing water meets the inflow temperature requirement of reverse osmosis unit, It is unfavorable for outside source of clean water, compares thermostat simultaneously and saved energy consumption, thermal power plant of the present utility model lower water temperature Device is suitable for coal-fired station's condenser discharge cycle and utilizes use.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing And specific embodiment is described in detail.
This utility model needs utilize external water source or increase the problem of energy consumption for existing condenser lower water temperature, carries For a kind of thermal power plant water temperature regulation device
As shown in Figure 1 and Figure 2, embodiment thermal power plant of the present utility model water temperature regulation device, including condenser water outlet Pipeline 1, mixing tank 2, mixing tank 2 is provided with mixing water outlet pipeline 3, and thermal power plant water temperature regulation device also includes heating Water tank 4 and control device, condenser outlet pipeline 1 is respectively communicated with mixing tank 2 and heating water tank 3, mixing tank 2 connection heating Between water tank 4, condenser outlet pipeline 1 and mixing tank 2 and heating water tank 4, between mixing tank 2 and heating water tank 4 and It is equipped with flow valve 5 on mixing water outlet pipeline 1, in heating water tank 4, is provided with electric heating tube 6, control device and include PLC control Device, temperature sensor 7, flow valve control circuit, temperature sensor 7 quantity is 3, is separately positioned on mixing tank 2 inside, adds Boiler 4 is internal, condenser outlet pipeline 1 is internal.
Temperature sensor 7 is used for measuring temperature, and flow valve 5 is used for opening and closing and the Flow-rate adjustment of pipeline.
The operation principle of this device is as follows;
When summer high temperature, condenser temperature at discharging condensate is more than 20 degree, and heating water tank 4 can disable, directly by condenser draining Reverse osmosis unit is introduced by mixing tank 2.
In the season that temperature is relatively low, condenser temperature at discharging condensate is less than 20 degree, but will be typically higher than 10 degree, now, opens and adds Boiler 4, starts electric heating tube 6, and PLC, according to the measured value of temperature sensor 7, controls to make mixing by flow valve 5 Water temperature in water tank 2 is maintained slightly above 20 degree, avoids the water Repeat-heating in heating water tank 4, energy efficient simultaneously.
In the case of condenser temperature at discharging condensate is higher than 30 degree, close between condenser discharge pipe line 1 and mixing tank 2 Flow valve, electric heating tube 6 does not enables, and condenser draining is after the gravity-flow ventilation of heating water tank 4 cools down, and temperature is reduced to 30 degree Hereinafter, reverse osmosis unit is being entered by mixing tank 2.
Preferably, heating water tank 4 volume is the half of mixing tank 2.
Preferably, heating water tank 4 surface is additionally provided with display control panel 8, and display control panel 8 includes display screen and knob Switch.
Preferably, control device also to include showing control circuit.
Display control panel 8 can be so that management personnel manipulate.
In such scheme, control device, heating water tank, mixing tank, condenser water outlet by arranging heating water tank and PLC Mixed connection between pipeline, by heating a small amount of water, so that it may so that mixing water meets the inflow temperature requirement of reverse osmosis unit, It is unfavorable for outside source of clean water, compares thermostat simultaneously and saved energy consumption, thermal power plant of the present utility model lower water temperature Device is suitable for coal-fired station's condenser discharge cycle and utilizes use.
The above is preferred implementation of the present utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of without departing from principle described in the utility model, it is also possible to make some improvements and modifications, these improve Also protection domain of the present utility model is should be regarded as with retouching.
