Embodiment one：It is house in 2012, the square meter of construction area about 20,000 to choose transformation area.Heat exchange station includes a radiating
Device unit and two tableland heating units)
| Area of heat-supply service | 23435㎡ | Heat supply amount | 210 families |
| Put into operation the time | 2012 | Building enclosure type | Three steps are saved |
Load is designed
System design parameterses table
(1) the civilian design heating index of this heat exchange station is according to 50W Lectotype and calculations, and Gongjian designs heating index and calculates choosing according to 70W
Type.According to floor heating with thermal center can and low-temperature heat source heat supply feature, and pilot station be three step energy-saving houses, primary side according to
45W can meet requirement completely, and secondary side relevant device is not changed.
(2) the secondary side pressure drop of floor heating heat exchanger device one great disparity, original is designed as 1kpa and 28kpa.So primary side flow
Increase nearly 6 times it is close with secondary side flow, also meeting heat exchange station once allows drag losses 50kpa requirement.Heat exchange station is used
Double crane units, are the plate type heat exchanger of symmetric form runner, and both sides fluid flow is roughly the same.
Fig. 1 is the floor plan of the present invention, and once water supply and the primary water pipeline that transformation area is chosen in figure are small around this
Entered the station after area's main building, cascade utilization needs the return piping newly laid, it is considered to former once to supply water and water return pipeline route pipe
Line is intensive, and the route that enters the station is longer, and engineering cost is high, therefore new return pipe road (distance is most short).Consider in addition, former water return pipeline
Road and new return pipe road keep certain distance also pipeline pump can be avoided to cause the partial circulating being likely to occur.
Fig. 2 is the structural representation of the present invention, a kind of efficient cascade utilization heating system that water is mixed with once net backwater, is led to
Cross the first control valve of setting, the second control valve, the 3rd control valve, the 4th control valve, first UNICOM's pipeline and second
The real primary water cascade utilization operating mode operation of UNICOM's pipeline, wherein the first control valve, the second control valve, the 4th regulating valve
Door is cast steel ball valve, and the 4th regulating valve is motor regulated valve；
By being provided with the variable frequency adjustment set on the secondary return pipe of circulating pump and the low area of Gongjian on new primary water pipeline
It is the variable frequency adjustment pump that is set on the circulating pump that is set on pump, radiator moisturizing branch pipe(tube), the civilian high secondary water return pipeline in area, civilian
The variable frequency adjustment pump that is set on the circulating pump that is set on high area's moisturizing branch pipe(tube), the civilian low secondary water return pipeline in area, civilian low area
The circulating pump set on moisturizing branch pipe(tube), with upper pump casing be set to overcome the stand internal resistance facility such as heat exchange station to provide power.
Transform the heating facility being related to and relate generally to the first control valve, the second control valve, the 3rd control valve, the 4th
Control valve, first UNICOM's pipeline and second UNICOM's pipeline, above structure is sets after transformation, other are to have set.
Operation need to first close the second control valve, the 3rd control valve, the 4th control valve after transformation, former once to supply water first
Through the low area's primary water pipeline of Gongjian, the second unicom pipeline, the first unicom pipeline and original one after the low area's heat-exchange unit of Gongjian
Secondary backwater is connected, collectively as civilian high area and the supply side of low area's heat-exchange unit, is returned after heat exchange through pipe circle pump supercharging
New primary water pipe.
When supply water temperature does not reach heat demand, the 3rd controlling opening of valve is adjusted, it is former once to supply water and the first UNICOM
Water realizes mixed water heat supply in pipeline.When accident occurs in the circulating pump of new primary water pipe, the first control valve and pipeline are closed
Pump valve, returns to former Heating State.
Heat-exchange unit is designed
Ground heating present situation heat exchanger model SHBR2, the ㎡ of monolithic effective area about 0.3, most large stretch of capacity 170.
Design before and after transformation all considers 20% surplus capacity, plus piece quantity is in maximum range, feasible.
After heat-exchange unit operating mode changes, logarithmic mean temperature difference (LMTD) reduction causes the increase of heat exchange area, so having carried out plus piece
Transformation.Through adjusting, the increase effect of heat exchanger runner is more than the value added of flow, and the pressure drop of unit both sides is all 5kpa, relatively former
If 1kpa and 28kpa, primary side has increase, secondary side significantly reduces.The circulating pump design discharge of new primary water pipeline
67.5m3/ h, rated lift 120kpa, select Grandfos TP100-130/4/4kw model circulating pumps, and use frequency control control
System processed.Secondary side circulating pump adapts to new operating mode using variable frequency adjustment.
This technology side when a pipe network return water temperature meets a theoretical heat supply temperature in station, is adjusted merely by frequency conversion
The rotating speed of pump is adjusted, changes secondary water-supply temperature, and is modified with secondary return water temperature, realizes that user's matter is adjusted.
When a pipe network return water temperature can not meet a theoretical heat supply temperature in station, pipe circle pump power frequency rotating speed,
The 3rd motor regulated valve aperture for adjusting the first water supply line sections realizes mixed water, i.e., first circulating pump is made power frequency and operated,
Water regulation is mixed carrying out the 3rd motor regulated valve.It is adjusted according to secondary network temperature adjustment curve, it is warm when not reaching water supply
When spending, start mixed water and reconcile pattern.
Coordinate transformation plan, region heat user man lays indoor temperature wireless monitoring device in transformation, and this is monitored in real time and is changed
Heat stations heat supply situation, whether heating effect reduces after verification checking transformation.
For monitoring heat exchange station heat transfer effect, stand in transform when unit secondary side installation calorimeter, can not only grasp plate
Heat transfer effect is changed, the change that user supplies thermic load, flow of adjustment and mixed water ratio can be also monitored in real time.
Primary side is different due to the heat supply temperature of the low area's radiator of Gongjian and civilian floor heating two systems, former one
The calculating heat exchange station heat consumption method of calorimeter is infeasible, and the flowmeter per heat-exchange unit need to be used to carry out calculation of heat rate and be added again
Obtain heat exchange station heat.
The technical program is main to increase circulating pump, the plate of plate type heat exchanger, new primary water on the basis of existing equipment
400,000 yuan of the preresearch estimates such as pipeline, the first unicom pipeline and the second unicom pipeline, valve, hotlist.Increase the electricity charge 0.6 newly per Heating Season
Wan Yuan.
It is 20,000 square meters because transformation district heating area is smaller, whole once water supply streams can be saved by transformation project
15t/h is measured, using backwater heat supply.Improving certain pipe network conveying capacity is used to develop new load, builds support expense income nearly 250
Wan Yuan, Benefit also provides new direction for low-temperature floor heating form.
An example of the present invention is described in detail above, but content is only presently preferred embodiments of the present invention, no
The practical range for limiting the present invention can be considered as.Any changes and modifications in accordance with the scope of the present application,
Within the patent covering scope that the present invention should still be belonged to.
