Compared with the prior art, the utility model discloses can realize the urgent hydrophobic or heat supply network sparge water of heat supply network and retrieve the way to heat supply network circulating pipe as the moisturizing, can reduce the maintenance cost that the power plant starts debugging and the improper run duration of heater.
Description
Technical field
This utility model relates to the Make-up Water for Heating System of Thermal Power Station, a kind of novel Make-up Water for Heating System.
Background technology
The Make-up Water for Heating System of conventional design uses plant area's chemical tendering water to be supplemented to Gateway Station in Heating Network oxygen-eliminating device mostly, delivers to heat supply network water return pipeline before circulation pump of heat-supply network after small pump boosts.Accident moisturizing is connected to before small pump inlet gate valve from plant area's industrial water system.This conventional system needs in a large number to system water supplement in heat network system initial start stage, and initial start stage is drawn gas and rinsed heat exchangers for district heating hydrophobic and be immediately discharged to cooling tower forebay or the hydrophobic heat of trench and water quality causes very big energy waste simultaneously.
Utility model content
The technical problems to be solved in the utility model is: existing Make-up Water for Heating System, when accident moisturizing, causes great energy waste, for solving the problems referred to above, it is provided that a kind of novel Make-up Water for Heating System.
The purpose of this utility model is achieved in that
A kind of novel Make-up Water for Heating System, including the high pressure heat exchangers for district heating being arranged in parallel and low pressure heat exchangers for district heating, all connect on high pressure heat exchangers for district heating and low pressure heat exchangers for district heating and have heating jet chimney, all connect on high pressure heat exchangers for district heating and low pressure heat exchangers for district heating and have two arms, after two arms import the most female pipe, being respectively connected to circulating water front pond and small pump, small pump receives from changing the water that water moisturizing pipeline comes simultaneously, after small pump boosts, import heat supply network recirculated water water return pipeline.
All connect on high pressure heat exchangers for district heating and low pressure heat exchangers for district heating and have heat supply network water return pipeline and heat supply network hot water pipeline.
High pressure heat exchangers for district heating and low pressure heat exchangers for district heating all arrange at least one.
Relative to prior art, this utility model is capable of that heat supply network is the most hydrophobic or heat supply network flushing water is recycled to heat supply network circulating water pipeline as moisturizing, it is possible to reduce the maintenance cost during power plant's Start-up and Adjustment and heater abnormal running.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein, 1 is high pressure heat exchangers for district heating；2 is low pressure heat exchangers for district heating；3 is small pump；4 is heating jet chimney I；5 is heating jet chimney II；6 is emergent drain pipeline I；7 is emergent drain pipeline II；8 is arm I；9 is arm II；10 is female pipe I；11 is female pipe II；12 being water moisturizing pipelines；13 is arm III；14 is arm IV；15 is heat supply network recirculated water water return pipeline；16 are off valve；17 is non-return valve；18 is electric gate valve；21 is heat supply network water return pipeline；22 is heat supply network water supply line.
Detailed description of the invention
As a example by 300MW unit heat supply is transformed, each emergent drain pipeline of 1,2 low pressure heat exchangers for district heatings 2 of 4 high pressure heat exchangers for district heatings of heat supply network heat supply initial station picks out a road arm.Each arm converges to female pipe and is connected to heat supply network small pump inlet stop valve preceding pipeline by non-return valve 17, as shown in Figure 1.
A kind of novel Make-up Water for Heating System, including high pressure heat exchangers for district heating 1, low pressure heat exchangers for district heating 2, heating jet chimney I 4, small pump 3, heating jet chimney 4 is connected with high pressure heat exchangers for district heating 1 by electric butterfly valve, heating jet chimney II 5 is connected with low pressure heat exchangers for district heating 2 by electric butterfly valve, change water moisturizing pipeline 12 is divided into 2 road arms III 13 and is connected with small pump 3 by non-return valve 17, is converged to heat supply network recirculated water water return pipeline 15 to heat network system moisturizing by arm IV 14 after boosting.Being designed with heat supply network water return pipeline 21 and heat supply network water supply line 22 in high and low pressure heat exchangers for district heating, the emergent drain pipeline I 6 of high pressure heat exchangers for district heating and low pressure heat exchangers for district heating and emergent drain pipeline II 7 remittance receive circulating water front pond to female pipe I 10.Draw arm I 8 and arm II 9 before electric gate valve 18 from emergent drain pipeline I 6 and emergent drain pipeline II 7 respectively to converge to female pipe II 11 through stop valve 16, on non-return valve 17 receiving water moisturizing pipeline 12.
Make-up Water for Heating System after optimization has following basic function: includes the equipment such as small pump 3, high and low pressure heat exchangers for district heating, is connected to heat supply network recirculated water water return pipeline by adnexaes such as pipelines.
1) heat exchangers for district heating flushing water
Utilize initial start stage to draw gas and rinse the hydrophobic of heat exchangers for district heating, provide moisturizing to heat supply network circulating backwater system, the hydrophobic heat and water quality that originally drained into cooling tower forebay or trench can be reclaimed completely, it is to avoid waste.Normal drain water piping is switched to after heat exchangers for district heating drain water quality is qualified.
2) heat supply network circulating cooling make-up water
When certain heat exchangers for district heating booster needs emergency blowoff, this part is the most hydrophobic accesses heat supply network recirculated water water return pipeline through small pump, supplements water as heat supply network, it is achieved water quality and the recovery of heat.
