With reference to Fig. 1, a kind of dragveyer pulp water is used for dragveyer pulp water liquid without excess flow control, the device including several
The guide wave radar liquid level gauge of position measurement and several temperature element (TEs measured for dragveyer slag water temperature, several guided wave radars
Liquid level gauge is arranged at the top of dragveyer slag ship；Several described temperature element (TEs are arranged on the side wall of dragveyer slag ship,
The side wall of dragveyer slag ship is equipped with the jack coordinated with temperature element (TE；The device further includes control system and is arranged on dragveyer
Moisturizing control valve in moisturizing pipeline, guide wave radar liquid level gauge are connected with temperature element (TE with the signal input part of control system,
Moisturizing control valve and the signal output part of control system connect.Guide wave radar liquid level gauge strong antijamming capability, improves liquid level survey
The reliability of amount, avoid the shortcomings that display using Fork LIquid Level Switch measurement without analog quantity；Guide wave radar liquid level gauge passes through
The mounting bracket that angle bar or channel steel make is fixed on the top of dragveyer slag ship, can not only overcome under this mal-condition of dragveyer
Pulp water ejecta pollution, it also avoid using ultrasonic level gage since pulp water ejecta pollution causes the inaccuracy of level gauging
And unreliability；The side wall of dragveyer slag ship is equipped with several equally distributed jacks, and temperature element (TE is plugged in jack, no
Only convenient installation, and the measurement of slag water temperature can be effectively carried out, detailed process is first to determine to need to install thermal resistance
The position of temperature element (TE, then slag shipboard wall is punched, after holding hole successfully, the installation of temperature element (TE sleeve is entered, last electricity consumption
Fixation is welded, welding will ensure faying face No leakage；Control system can be using the control system of PLC devices in order to control, receive
The liquid level and temperature signal of guide wave radar liquid level gauge and the pulp water of temperature element (TE measurement, and then control the supply of pulp water；Moisturizing control
System processed is used for the switch for controlling moisturizing pipeline, facilitates the control of moisturizing；The characteristics of the utility model is maximum is exactly to use guided wave
Radar surveying liquid level and temperature element (TE measurement slag water temperature, guided wave radar improve the reliability of level gauging, and temperature element (TE is surveyed
Amount also more accurately and reliably reflects the actual temperature of pulp water, on the premise of the normal operation of dragveyer is ensured, maximum limit
Degree ground energy-saving and water-saving.
The guide wave radar liquid level gauge is equipped with 2, and 2 guide wave radar liquid level gauges are separately positioned on dragveyer slag ship both sides
Top.The setting of 2 guide wave radar liquid level gauges further increases the accuracy of pulp water level gauging so that the pulp water liquid of measurement
Position is more true and reliable, during value, takes the average value of the liquid level of 2 guide wave radar liquid level gauges.
Distance of the guide wave radar liquid level gauge at the top of dragveyer is 1-1.5m.The guide wave radar liquid level gauge distance
Optimal distance at the top of dragveyer is 1.1m, not only it is possible to prevente effectively from the splashing of pulp water, but also can effectively be launched downwards

The temperature element (TE is equipped with 3, and 3 temperature element (TEs are evenly distributed on the side wall of dragveyer slag ship lower part.3 temperature
Degree element can more accurately and reliably reflect the actual temperature of pulp water, avoid single temperature element (TE measurement generating device
Caused by failure the shortcomings of system shutdown, the normal table operation of dragveyer is effectively guaranteed, during value, takes 3 temperature members
The intermediate value or average value of the temperature signal of part measurement.
The temperature element (TE is thermal resistance.Thermistor Temperature Measurement is that the resistance value based on metallic conductor increases with the increase of temperature
Add this characteristic to carry out temperature survey, feature is high certainty of measurement, and performance is stablized.
The control system is DCS control systems.DCS control systems, also referred to as Distributed Control System, be using microprocessor as
Basis, is disperseed, display operation is concentrated, taken into account point and the instrument of new generation of design principle that is autonomous and synthesizing and coordinating using control function
Table control system, can accurately receive the measuring signal of guide wave radar liquid level gauge and temperature element (TE, then signal Analysis, control
Moisturizing controls moisturizing of the valve events to dragveyer.
The moisturizing control valve is switching mode motor-driven valve.Switching mode motor-driven valve logic control is simple, easy to control filling pipe
Road carries out dragveyer moisturizing, and switching mode motor-driven valve can also have the function of that centre is stopped, easy to the control of rate of water make-up.
With reference to Fig. 2, control logic main task one is the real-time condition display of slag ship slag water temperature and pulp water liquid level, second,
Moisturizing control valve automatically controls, it is therefore an objective to intelligent control is changed to by manually adjusting rate of water make-up at present, when slag ship pulp water
When the excessive either pulp water liquid level of temperature is relatively low duration impulse 3 seconds automatically turn on slag ship moisturizing door when slag ship slag water temperature is low or
Slag ship moisturizing door is automatically closed when pulp water liquid level height and low slag water temperature.
The utility model is applied in practice, and the utility model technology is used with two 330MW unit dragveyers pulp waters
Economic and Efficiency Analysis is as follows after transformation：
(1) overflow water pump saves power consumption expense：2 non-firm power 45KW each other are equipped with by a 330MW units dragveyer
Overflow water pump, when total operation 5-8 is small daily, rate for incorporation into the power network is by 0.424 yuan/degree rough calculation, two unit dragveyer overflows
It is as follows that water pump saves power consumption expense：
1=2 × 45 × 8=720KW of consumption power P daily
Wastage in bulk or weight electricity W1=P1 × 365=262800KWh
0.424 yuan of rate for incorporation into the power network/degree
Save power consumption expense S1=W1 × 0.424=11.14272 ten thousand yuan
(2) overflow water saves expense：One 330MW units dragveyer is by one hour overflowing ash water, 5 tons of calculating, two units
It it is exactly 10 tons, industrial circulating water per ton is by 0.265 yuan of rough calculation：
Year can save water S=10 × 24 × 365=87600 ton
Year can save water expense S2=87600 × 0.265=2.3214 ten thousand yuan
(3) comprehensive benefit.Ten thousand yuan of comprehensive benefit S=S1+S2=11.14272+2.3214=13.46432
In conclusion two 330MW unit dragveyer slag ship cooling waters comprehensive treatment schemes can create warp every year after implementing
About 13.46 ten thousand yuan of benefit of Ji, energy-saving benefit is considerable.
