Background technology
In present most heat supply initial station, steam pressure is typically higher, is partly into heat exchangers for district heating and user is supplied
Warm to be heated with water, another part drags circulating pump to circulate the heating water of user by back pressure turbine, and steam passes through
Exhaust steam pressure after back pressure turbine is typically relatively low, about 0.1~0.25MPa, and well below main steam pressure, and pressure is relatively low
Exhaust steam can not then enter back into heat exchangers for district heating use, the exhaust steam arranged outside back pressure turbine or cause wave by directly discharging
Take, or the exhaust steam arranged outside back pressure turbine is absorbed by the way of an exhaust steam heat exchanger is increased, with heat exchangers for district heating shape
Into parallel connection, the heating water of user is heated jointly.Increase exhaust steam heat exchanger, so undoubtedly add the complexity of configuration in station
Degree, piping is complicated, and installation cost is high.

Left end socket is provided with the left of described housing, right end socket is provided with the right side of housing, described left end socket top is provided with out
The mouth of a river, bottom are provided with water inlet, and the top of described housing is provided with high pressure steam inlet, and bottom is provided with drain port, with
The right side of the connected housing of right end socket extends one section as additional housing, the top of additional housing be provided with communicated with its inner chamber it is low
Press steam inlet, bottom is provided with additional drain port, the interior intracavitary between described additional housing and housing be provided with partial pressure every
Plate, the external diameter of described partial pressure dividing plate match with the internal diameter of additional housing.
The thickness of described partial pressure dividing plate is more than 50mm.
Described low pressure steam inlet is located at the centre position of additional housing upper, and described additional drain port is positioned at additional
The centre position of lower housing portion.
Additional condensate liquid level gauge is provided with the downside of described additional housing.
Condensate liquid level gauge is provided with the downside of described housing.
Described high pressure steam inlet includes two, is separately positioned on the left and right sides of housing upper.
Compared to the prior art partial pressure type heat exchangers for district heating of the present utility model, has beneficial effect following prominent：No
Need to increase the exhaust steam recycling that exhaust steam heat exchanger can also discharge back pressure turbine, simplify system, reduce capital cost
The features such as using.

Embodiment
Partial pressure type heat exchangers for district heating of the present utility model is described in detail below with reference to Figure of description 1.
Partial pressure type heat exchangers for district heating of the present utility model, its structure includes housing 1, left end socket 2 and right end socket 3, described
The left side of housing 1 is provided with left end socket 2, and the right side of housing 1 is provided with right end socket 3, and the described top of left end socket 2 is provided with water outlet
Mouth 4, bottom is provided with water inlet 5, and the top of described housing 1 is provided with high pressure steam inlet 6, and bottom is provided with drain port 7,
The right side for the housing 1 being connected with right end socket 3 extends one section as additional housing 8, and the top of additional housing 8 is provided with and its inner chamber phase
Logical low pressure steam inlet 9, bottom are provided with additional drain port 10, and the interior intracavitary between described additional housing 8 and housing 1 is set
Partial pressure dividing plate 11 is equipped with, the external diameter of described partial pressure dividing plate 11 matches with the internal diameter of additional housing 8.
The thickness of described partial pressure dividing plate 11 is more than 50mm.
Described low pressure steam inlet 9 is located at the centre position on the additional top of housing 8, and described additional drain port 10 is located at
The centre position of the additional bottom of housing 8.
The downside of described additional housing 8 is provided with additional condensate liquid level gauge 12.It is solidifying in additional housing 8 for detecting
Position is born water, when reaching certain value, additional drain port 10 is opened and discharges condensate.
The downside of described housing 1 is provided with condensate liquid level gauge 13.For detecting the condensation water level in housing 1, when up to
During to certain value, open drain port 7 and discharge condensate.
Described high pressure steam inlet 6 includes two, is separately positioned on the left and right sides on the top of housing 1.It is easy to high pressure to steam
Vapour preferably with the water inlet contact heat-exchanging in housing 1.
Partial pressure type heat exchangers for district heating of the present utility model can realize that two strands of steam of high and low pressure respectively enter heater, without
Colliding with each other for pressure can be produced and influence low pressure admission.The high pressure main steam directly come out of heat supply initial station is directly steamed along high pressure
Vapor inlet enters housing, and the exhaust steam that the pressure of back pressure turbine discharge is relatively low enters additional housing from low pressure steam inlet, respectively
Heating water in housing is heated, the partial pressure dividing plate 11 minimum thickness 50mm, thickeied according to the situation of pressure differential.This
Sample, when high steam is flowed by the gap of partial pressure dividing plate 11 and additional housing 8 to low-pressure steam side, constantly it is condensed,
Condensate forms water resistance between gap caused by condensation, effectively prevent influence of the high steam to low-pressure steam side, makes low pressure
It is unblocked to enter vapour.
