With the second manually-operated gate 135 in the state of shutdown, from returning in the water and water return pipeline 120 that high water tank 131 flows out
Water can not all reach the first control valve 133, convenient to work such as the replacements and maintenance of the first control valve 133.Also, it is logical
The first bypass valve 136 of setting is crossed, it can be in the first control valve 133, first manual valve 134 or the second manually-operated gate 135
When failure, the connection between high water tank 131 and water return pipeline 120 can be controlled by the first bypass valve 136, this
One bypass valve 136 can be used as spare.
On the basis of above scheme, optionally, the water in moisturizing source 230 is chemistry water, moisturizing source 230 and high water tank
Second control valve 137 is set between 131.
Because (pressure rating difference has middle pressure, high pressure to boiler of power plant high temperature (a few Baidu) high pressure.It is super-pressure, subcritical, super
It is critical etc.), and there is certain water evaporation to fall, under these conditions, any impurity all can be highly concentrated in water, if impurities in water
It is slightly more, it is possible to fouling, corrosion etc., it is easy to cause the accident.Chemistry impurities in water is less, so that phenomena such as fouling, corrosion
It reduces, advantageously reduces the generation of accident.
Second control valve 137 is set between moisturizing source 230 and high water tank 131, by adjusting second control valve
137, the water for the chemistry water that adjustable moisturizing source 230 is conveyed to high water tank 131, for example, when water in high water tank 131
When measuring less, the speed of the water delivery into high water tank 131 of moisturizing source 230 can be accelerated by the second control valve 137 of control,
When water is more in high water tank 131, moisturizing source 230 can be reduced to high water tank by controlling the second control valve 137
The speed of 131 water deliverys.
On the basis of above scheme, optionally, third manually-operated gate is respectively set in the two sides of the second control valve 137
138 and the 4th manually-operated gate 139, the second bypass valve 140, the second bypass are also set up between moisturizing source 230 and high water tank 131
140 side of valve is connected to third manually-operated gate 138 close to the side in moisturizing source 230, the other side of the second bypass valve 140 with
4th manually-operated gate 139 is connected to close to the side of high water tank 131.
By the way that third manually-operated gate 138 and the 4th manually-operated gate 139 is respectively set in the two sides of the second control valve 137,
It can make third manually-operated gate 138 and the 4th manually-operated gate 139 in the state of shutdown, the water flowed out from moisturizing source 230, with
And the water in high water tank 131, it can not all reach the second control valve 137, convenient replacement and dimension to the second control valve 137
The work such as repair.Also, by setting the second bypass valve 140, can the second control valve 137, third manually-operated gate 138 or
When 4th manually-operated gate 139 breaks down, can be controlled by the second bypass valve 140 moisturizing source 230 and high water tank 131 it
Between connection, which can be used as spare.
On the basis of above scheme, optionally, the top of high water tank 131 is communicated with the atmosphere.
It is existing that the air carried secretly in heat supply network return water is discharged by automatic exhaust steam valve, the air carried secretly in return water cannot be discharged
Completely, heat supply network pressure of return water is made to be affected.It is communicated with the atmosphere by the way that 131 top of high water tank is arranged, so that water return pipeline 120
In gas can be directly released into atmosphere by high water tank 131 so that the quilt in time of the gas in water return pipeline 120
Emit, so will not because gas there are due to influence pressure of return water in water return pipeline 120.
On the basis of above scheme, optionally, water level in the bottom surface absolute altitude and high water tank 131 of high water tank 131
The sum of height is more than or equal to 23 meters and is less than or 25 meters.
The bottom surface absolute altitude of high water tank 131 is more than or equal to 23 meters with the sum of the water level in high water tank 131 and is less than
Or it is equal to 25 meters, for example, can control the water level in water tank is 0-2 meters when the bottom surface absolute altitude of high water tank 131 is 23 meters, into
And can guarantee that the pressure of return water of heat supply network remains between 0.23-0.25Mpa, it is gas-entrained in heat supply network return water or have
When abnormal conditions cause return water superpressure, gas and release water hammer pressure can be automatically drained out by high water tank 131.Also, heat supply network
Pressure of return water is maintained between 0.23-0.25Mpa, pump cavitation caused by pressure of return water can be prevented too low, and can be to prevent
Energy dissipation caused by non-return water hypertonia.
On the basis of above scheme, optionally, water return pipeline 120 includes that at least one return water handles branch 121, return water
Handling branch 121 includes back water pump 1211, and back water pump 1211 is arranged in close to the filter of 210 side of outer net heat exchange station
1212, and filter 1212 is set close to the return water inlet valve 1213 of heat supply network heat exchange station side, and be arranged in return water
1212 non-return flaps 1214 close to 220 side of heat exchangers for district heating are pumped, and are arranged in non-return flap 1214 close to heat exchangers for district heating 220
The backwater outlet valve 1215 of side.
Water returns to heat exchangers for district heating 220, once after outer net heat exchange station 210 carries out surface heating to secondary water
Water might have the impurity in pipeline and be mixed into a water, in order to avoid impurity enters heat exchangers for district heating in cyclic process
220, settable return water handles branch 121, and the filter 1212 in return water processing branch 121 can be filtered return water,
Then under the pressure effect that back water pump 1211 provides, heat exchangers for district heating 220 is entered.It is arranged in back water pump 1211 close to heat supply network
The non-return flap 1214 of 220 side of heater can anti-non-return water refluence.In addition, passing through inlet porting valve 1213 and outlet valve
1215, inlet valve 1213 and outlet valve 1215 can be closed, is made when back water pump 1211 or filter 1212 break down
Filter 1212 and back water pump 1211, the convenient service work to filter 1212 and back water pump 1211 will not be reached by obtaining return water.
On the basis of above scheme, optionally, side and return water of the inlet pipeline 110 close to outer net heat exchange station 210
Pipeline 120 is additionally provided with flowmeter close to the side of outer net heat exchange station 210.
By in inlet pipeline 110 close to the side of outer net heat exchange station 210 and water return pipeline 120 close to heat supply network heat exchange station
Side be provided with flowmeter 152, can be facilitated each in Make-up Water for Heating System with the flow in real-time detection inlet pipeline 110
Kind parameter calculates.Flowmeter is set close to the side of outer net heat exchange station 210 in water return pipeline 120, can detecte circling water flow rate, side
Just to the monitoring of Make-up Water for Heating System.
With continued reference to Fig. 2, Make-up Water for Heating System provided in this embodiment can also retain existing small pump moisturizing branch
160, using as spare.
Make-up Water for Heating System provided in this embodiment, the top by the way that high water tank is arranged is communicated with the atmosphere, so that return water
Gas in pipeline can be directly released into atmosphere by high water tank, so that the gas in water return pipeline is arranged in time
Run out, so will not because gas there are due to influence pressure of return water in water return pipeline；And the bottom surface of setting high water tank
The sum of water level in absolute altitude and high water tank is more than or equal to 23 meters and less than or equal to 25 meter, and example can guarantee heat supply network
