Description
Technical field
The invention belongs to power plant auxiliary machine field.
Background technology
Steam power plant or the heat exchangers for district heating of other heating systems, to ensure that unit operation is stable, it is typically provided and drainage pump
Adaptable hydrophobic well.The setting of hydrophobic well is separately provided a drain trap typically using split type in equipment bottom.Also have
In heat exchangers for district heating cylinder body bottom, the horizontal hydrophobic well construction of semicircle (the hydrophobic well of abbreviation bottom integral type) is set.
Shortcomings：Heat exchangers for district heating space-consuming using split type hydrophobic well is big, high material consumption, manufacturing cost
Height, water level control are complicated.Using the heat exchangers for district heating of the hydrophobic well of bottom integral type, hydrophobic well end plate stress condition is poor, and material disappears
Consumption is big, high equipment cost, and thin cold section of invalid heat exchange area is big, and it is immersion to dredge cold section, and water level control is complicated.
The content of the invention
It is an object of the invention to：In order to improve the stressing conditions of hydrophobic well, there is provided a kind of heat of built-in hydrophobic well construction
Net heater, the heat exchangers for district heating not only optimize the stressing conditions of hydrophobic well, alleviate steam to the impact of tube bank, simplify
Water level control, avoid thin cold section of low water level and run without water level, and improve heat exchange efficiency, stable equipment operation, take
Space is small, and equipment consumptive material is few.
The object of the invention is realized by following technical proposals：
Hydrophobic well heat exchangers for district heating built in one kind, including shell, shell include the stack shell and shell ring being connected, set in shell
There is heat-exchanging tube bundle, heat-exchanging tube bundle is divided into saturation section and dredges cold section, and shell also includes the eccentric shell being connected with stack shell and shell ring, eccentric
Shell phase is eccentric downwards to stack shell and shell ring, and the eccentric shell sinks to forming a hydrophobic well below relative stack shell and shell ring bottom, dredges
Well controlling water level is controlled between heat-exchanging tube bundle bottom to stack shell and shell ring bottom, and thin cold section of heat-exchanging tube bundle is hydrocone type knot
Structure, it dredges the bottom that cold section of inlet tube is deep into eccentric shell, and below outer casing centerline, the heat-exchanging tube bundle dredged outside cold section is still made
For saturation section.
The eccentric shell lower space of the present invention is hydrophobic well, and storage is a certain amount of hydrophobic.When equipment is run, steam passes through steaming
Vapor inlet pipe enters heater, in the heat transfer of equipment saturation section, is condensed into the hydrophobic hydrophobic well for converging in device bottom.Water level is higher than
When dredging cold section of inlet tube, dredge cold section of water seal and formed, it is hydrophobic by siphonage, into dredging cold section and being full of, finally from hydrophobic
Outlet outflow heater, complete to dredge cold section of heat exchange.Equipment controlling water level control heat-exchanging tube bundle bottom to stack shell bottom it
Between, even lowest water level can also ensure the hydrophobic amount of eccentric shell bottom, it is ensured that the operation of heat exchangers for district heating drainage pump.Run water
Position is very big away from cold section of inlet tube distance is dredged, and much larger than artifical water height value, avoids and cold section of air inlet is dredged caused by erroneous judgement.As a result of
Hydrocone type dredges cold section, and below equipment center line, the heat exchanger tube dredged outside cold section can still be exchanged heat as saturation section.With submergence
Formula compares, and takes full advantage of this region heat exchange area, reduces invalid.
Alternatively, hydrophobic bottom sets emergent drain mouth and/or dewatering outlet.In the program, dewatering outlet can basis
Need to set, can be separately provided, emergent drain pipeline minimum point can also be arranged on.
Alternatively, roller slideway is installed between heat-exchanging tube bundle and shell.
As further selection, roller slideway is by the roller on heat-exchanging tube bundle and eccentric shell and the track structure of stack shell bottom
Into.In the program, housing and tube bank between be provided with roller slideway support, assembling it is time saving and energy saving, avoid tube bank scratch and tube sheet
Locate the failure by shear of heat exchanger tube.
Alternatively, steam inlet, hydrophobic outlet, level measuring sample tap are additionally provided with shell.
The foregoing main scheme of the present invention and its each further selection scheme can be this with independent assortment to form multiple schemes
The scheme that invention can be used and is claimed；And the present invention, between (each non conflicting selection) selection and between other selections
Can also independent assortment.Those skilled in the art can understand have after the present invention program is understood according to prior art and common knowledge
Multiple combinations, it is the claimed technical scheme of the present invention, does not do exhaustion herein.
Beneficial effects of the present invention：On the one hand improved hydrophobic into built-in hydrophobic well by eccentric hull shape in the present invention
Well stress, stable connection, safety, is easily installed, and equipment occupation space is small, consumptive material is few, heat exchange efficiency is high；On the other hand, steam
Porch employs eccentric shell, expands steam circulation area, reduces steam flow rate, alleviates steam and tube bank is washed away,
Eliminate the risk factor of tube vibration and booster.Meanwhile employ hydrocone type and dredge cold section, below equipment center line, dredge cold section it is outer
Heat exchanger tube can still be exchanged heat as saturation section.Compared with immersion, this region heat exchange area is taken full advantage of, is reduced
Invalid.In addition, between housing and tube bank be provided with roller slideway support, assembling it is time saving and energy saving, avoid tube bank scratch and
The failure by shear of heat exchanger tube at tube sheet.
