Specific embodiment
As shown in Figure 1, the utility model provides a kind of novel heat supply network draining system, including heat exchangers for district heating component and heating
The hydrophobic pump assembly of device, heat exchangers for district heating component include heat exchangers for district heating 1 and hydrophobic index combustion fan 2, hydrophobic index combustion fan 2
In on the hydrophobic pipeline a3 being connected with the water outlet of heat exchangers for district heating 1；
Heater condensate pump assembly includes heater-drip pump 4 and drainage pump index combustion fan 5, drainage pump index combustion fan
5 are located on the hydrophobic pipeline b6 being connected with the water outlet of heater-drip pump 4；
Hydrophobic pipeline a3 is connected with the water injection end of heater-drip pump 4.
Wherein, the water injection end of heat exchangers for district heating 1 is connected with steam bleeding system.
Wherein, the water outlet of hydrophobic pipeline b6 is connected with former condensate system.
In the present invention, the effect of heat exchangers for district heating is that heat supply network is recycled by heat exchangers for district heating for heating steam
After water heating, steam condensation becomes hydrophobic.
The effect of heat exchangers for district heating drainage pump be by heat exchangers for district heating outlet it is hydrophobic boost to suitable pressure after, enter
Former condensate system is recycled.
By heat exchangers for district heating heat cycles water, steam is closed cycle for heating steam extraction, hydrophobic all recycling, due to this portion
Dividing water is therefore to send 1,2 back to respectively by heat supply network drainage pump from condensed water of the main building extracted steam from turbine after heat exchange condensation
Number owner's workshop condensate system, until the equipment to match (need to determine, with not shadow according to different situations and the cooperation of host producer
Ringing original system is principle) heater-drip pump selects 5, wherein 4 operations, 2 drainage pumps respectively correspond 2 heat supply network heating
Device, 1 as public spare.
Two heat exchangers for district heatings use a draining system, and heating steam comes from a jet chimney, two heaters it
Between water level can be almost the same.In view of runing time it is longer after, corresponding two heat exchangers for district heating foulings of every unit etc. because
The influence of element, the pressure drop difference bring water-head of equipment itself are provided with hydrophobic on the hydrophobic export pipeline of heat exchangers for district heating
Index combustion fan is come the situation that overcomes water level inconsistent.
It is last hydrophobic after the boosting of heat supply network drainage pump, by the distribution of heater-drip pump index combustion fan, respectively
Return former condensate system.
The above is only the preferred embodiment of the present invention, is merely illustrative for invention, rather than limits
Property.Those skilled in the art understand that in the spirit and scope defined by invention claim many changes can be carried out to it,
It modifies or even equivalent, but all will fall within the protection scope of the utility model.
