In, the First Heat Exchanger 1 is plate heat exchanger, and second heat exchanger 2 is shell-and-tube heat exchanger.
Combined hot exchange system described in the utility model when in use, specifically includes following operating method:
Operating method one: it is changed as shown in Figure 1, fluid media (medium) (bath wastewater) enters first from first fluid channel entrance 31
Hot device 1 is flowed out after the heat exchange of First Heat Exchanger 1 by first fluid channel outlet 32；Fluid media (medium) (flue gas) is from third stream
Body channel entrance 51 enters the second heat exchanger 2, is flowed out after the heat exchange of the second heat exchanger 2 by third outlet flow channels 52；It is above-mentioned
Different fluid media (medium)s is by carrying out energy exchange while heat exchanger.
Fluid media (medium) (tap water) enters from second fluid channel entrance 41, enters first through first flow control valve 6 and changes
After the interior absorption thermal energy of hot device 1, the second heat exchanger 2 absorption thermal energy is sequentially entered, is finally exported by second fluid channel outlet 42.Such as
Shown in Fig. 1, fluid media (medium) can also be imported by fluid media (medium) inlet and outlet 43, enters second fluid through second flow control valve 9
In channel 4.At this point, the fluid that the fluid media (medium) and fluid media (medium) inlet and outlet 43 that are imported by second fluid channel entrance 41 import is situated between
Matter can be identical type, be also possible to variety classes.
In above process, the temperature signal that the controller 7 is acquired according to temperature sensor 8 is controlled respectively by signal wire
First flow control valve 6 processed, second flow control valve 9.When the numerical value of temperature sensor 8 is lower than setting value, controller 7 is to the
Two flow control valves 9 send instruction to reduce fluid media (medium) through fluid media (medium) inlet and outlet 43 and flow into, while controlling to first flow
Valve 6 sends instruction to increase fluid media (medium) through second fluid channel entrance 41 and flow into；On the contrary, the numerical value when temperature sensor 8 is high
When setting value, controller 7 sends instruction to second flow control valve 9 to increase fluid media (medium) through 43 stream of fluid media (medium) inlet and outlet
Enter, while sending instruction to first flow control valve 6 to reduce fluid media (medium) through the inflow of second fluid channel entrance 41, Jin Ershi
Within the set range from the temperature of the fluid media (medium) of the outflow of second fluid channel outlet 42, flow now.
Using a kind of scheme of the operating method one of combined hot exchange system described in the utility model, can either sufficiently return
The low temperature exhaust heat of bath wastewater is received, and can safely recycle high-temperature residual heat entrained by flue gas.If bath wastewater is 30
DEG C, tap water be 15 DEG C, flue gas is 150 DEG C, First Heat Exchanger 1 is plate heat exchanger, and the second heat exchanger 2 changes for shell-and-tube
Hot device, since the heat exchange efficiency of plate heat exchanger is high, small there are about 1 DEG C, the tap water after plate heat exchanger exchanges heat is lost in heat exchange
Leaving water temperature can achieve 29 DEG C.The thermal energy that identical quantity tap water is absorbed from bath wastewater is 14 DEG C；If using shell
The loss that then exchanges heat of formula heat exchanger reaches 5 DEG C, and the temperature of tap water is 25 DEG C after heat exchange, and identical quantity tap water is from bath wastewater
The thermal energy of absorption is 10 DEG C, reduces 29% compared to plate heat exchanger；If 150 DEG C are absorbed using plate heat exchanger simultaneously
Waste heat in flue gas can then seriously affect the safety fortune of plate heat exchanger since tap water and the flue gas temperature difference are larger
Row.
Operating method two: as shown in Fig. 2, when fluid media (medium) inlet and outlet 43 are exported as fluid media (medium) in use, first-class
In body channel 3, third fluid channel 5 fluid media (medium) flow direction it is identical with operating method one, tap water through second fluid channel into
Mouthfuls 41 enter, the tap water through 43 outflow lower temperatures of fluid media (medium) inlet and outlet, can be used to wash one's face and rinse one's mouth, bathing, logical through second fluid
The tap water of 42 outflow higher temperature of road outlet, can be used to warm oneself, dry.Combined hot exchange system described in the utility model can
To export the tap water of two kinds of different temperatures.
Operating method three: as shown in Fig. 2, the fluid media (medium) in the second fluid channel 4 is that (temperature is about saturated vapor
180 DEG C) when, First Heat Exchanger 1 is shell-and-tube heat exchanger, and the second heat exchanger 2 is plate heat exchanger, through the first fluid channel
The fluid media (medium) that import 31 flows into can be softened water, pure water, anti-icing fluid etc., the stream flowed into through the third fluid channel 51
Body medium can be tap water.Fluid media (medium) saturated vapor in second fluid channel 4 by second fluid channel entrance 41 into
Enter, exported through second fluid channel outlet 42, saturated vapor completes heat exchange after flowing through First Heat Exchanger 1, is become by steam
Liquid；The liquid is exported after the heat exchange of the second heat exchanger 2 by second fluid channel outlet 42.At the same time, through described first
The fluid media (medium) that fluid channel inlet 31 imports is exported after heat exchange by first fluid channel outlet 32, the temperature of fluid medium
About 50 DEG C -80 DEG C, for warming oneself, drying；The fluid media (medium) imported through the third fluid channel inlet 51 is after heat exchange
It is exported by third outlet flow channels 52, which is about 30 DEG C -50 DEG C, for washing one's face and rinsing one's mouth, bathing etc..
It should be noted that have fluid media (medium) in the First Heat Exchanger 1, the second heat exchanger 2, the friendship for heat
It changes.
In conclusion plate heat exchanger can be given full play to using a kind of combined hot exchange system described in the utility model
The feature that heat waste is few, the temperature difference is small recycles low temperature heat energy, while it is big again to give full play to shell-and-tube heat exchanger high temperature resistant, the temperature difference
Feature absorbs high temperature heat.
