Description
Technical field
The utility model relates to the hydrophobic retracting device of a kind of overcritical heating unit heat exchangers for district heating.
Background technology
Usually enter oxygen-eliminating device by the heat exchangers for district heating drainage pump in that the heat exchangers for district heating of subcritical heating unit is hydrophobic, reach the purpose that reclaims working medium and heat.For subcritical drum boiler continuous blowdown system of boiler and periodical blowdown system are arranged, can purify stove water,, guarantee unit safety operation even heat exchangers for district heating has a spot of leakage also can not influence the steam quality of whole system by blowdown.Boiler for overcritical heat supply unit is a direct current cooker, does not have continuous blowdown and periodical blowdown system, how to reclaim the hydrophobic of heat exchangers for district heating, reaches the purpose that reclaims heat, can guarantee that again the stove water of unit reaches water standard, makes unit that better economy be arranged.
Summary of the invention
The purpose of this utility model is exactly to the hydrophobic recovery of carrying out working medium and heat of the heat exchangers for district heating of overcritical heating unit, and does not influence the water quality of boiler feedwater.
For achieving the above object, the utility model is by the following technical solutions:
The hydrophobic retracting device of a kind of overcritical heating unit heat exchangers for district heating, it comprises at least one heat exchangers for district heating, establish conductivity apparatus and heat exchangers for district heating drainage pump on the hydrophobic outlet conduit of each heat exchangers for district heating, the heat exchangers for district heating drainage pump boosts and is delivered to condensing water conduit through tramp iron separator and enters oxygen-eliminating device; And on the inlet duct of described heat exchangers for district heating drainage pump fast valve is set, fast valve and conductivity apparatus are chain, establish the flow of control valve control heat exchangers for district heating drainage pump outlet behind the heat exchangers for district heating drainage pump.
The urgent drain valve of heat exchangers for district heating is set on the hydrophobic outlet conduit of each heat exchangers for district heating.
Adopt the utility model of technique scheme, by the conductivity apparatus of measuring hydrophobic electrical conductivity and the setting of several systems bypass are set, when guaranteeing the boiler feedwater quality, finish the recovery of hydrophobic working medium of heat exchangers for district heating and heat, solve hydrophobic recovery of overcritical heating unit heat exchangers for district heating and heat recovery, improved the performance driving economy of unit.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, strengthen the caliber of heat exchangers for district heating drain water piping, establish conductivity apparatus 1 on heat exchangers for district heating 2 hydrophobic outlet conduits, being boosted by heat exchangers for district heating 2 drainage pumps when hydrophobic electrical conductivity is in allowed band is delivered to condensing water conduit through tramp iron separator 3 and enters oxygen-eliminating device.
On heat exchangers for district heating drainage pump 4 inlet ducts, increase fast valve 5, this fast valve 5 is chain with conductivity apparatus 1, establish the flow of control valve 6 control heat exchangers for district heating drainage pumps 4 outlets behind the heat exchangers for district heating drainage pump 4, thereby regulate the water level of heat exchangers for district heating 2, reaching and reclaiming working medium has the purpose that reclaims heat.
When having necessarily, hydrophobic electrical conductivity exceeds standard, but when the water level of heat exchangers for district heating 2 does not obviously raise, illustrate that heat exchangers for district heating 2 heat exchanger tubes have the seepage phenomenon, the fast valve 5 of heat exchangers for district heating drainage pump 4 inlets cuts out, open to the drain regulating valve 7 of condenser dewatering capacity-enlarging device simultaneously, hydrophobicly can enter unit condenser dewatering capacity-enlarging device by drain regulating valve 7, thereby entering condensate system handles by the condensed water precision processing system of changing the water major setting, though this system does not reclaim the hydrophobic heat of heat supply network, but reclaimed this part working medium, the process condensed water precision processing system has guaranteed the water quality of boiler feedwater, need not excise the heat supply that heat exchangers for district heating can satisfy unit to greatest extent in addition.
The hydrophobic far super permissible value of electrical conductivity on heat exchangers for district heating outlet drain water piping, meanwhile the water level of heat exchangers for district heating has obvious rising again, the fracture of heat exchangers for district heating heat exchanger tube is described, at this moment the fast valve 5 of drainage pump inlet cuts out, open the urgent drain valve 8 of heat exchangers for district heating simultaneously, in time excise hydrophobic the drain into boiler body dewatering capacity-enlarging device of this heat exchangers for district heating heat exchangers for district heating.
