Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is the structural representation of the robot control system(RCS) of the utility model control exhaust gas temperature.
Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
It is as follows referring to Fig. 1 operation principles of the present utility model：Energy-saving appliance amount of inlet water system mainly includes temperature sensor
1st, electric T-shaped valve 3, valve, accessory instrument and pipeline composition.It is provided with before electric T-shaped valve 3 at stop valve 4, stop valve 4
In normally opened state；Reducing 5 is respectively housed before stop valve 4 and after electric T-shaped valve 3；Pressure is installed on energy-saving appliance inlet pipeline 6
Table 13, thermometer 14, air bleeding valve 7；Pressure gauge 13, thermometer 14, safety valve 15, cut-off are installed on energy-saving appliance outlet pipeline 12
Valve 10, and stop valve 10 is in normally opened state；The system, which is provided with bypass line 9, bypass line 9, is equipped with stop valve 8, cut-off
Valve 8 is in normally off.
The system sets fixed exhaust gas temperature T0, T0 a value more than flue gas dew point temperature at energy-saving appliance exhaust pass smoke evacuation
Spend and leave surplus.Chimney meatus transmitting smoke temperature is sent to electric T-shaped valve 3, electric three passes by temperature sensor 1 by sensing line 2
Proportional integration temperature controller in valve 3 automatic can set a temperature range with T0 values, and the detected value of temperature sensor 1 is with setting
Definite value T0 constantly compares, while constantly output signal, controls the aperture of electric T-shaped valve 3, be finally maintained at exhaust gas temperature
In the T0 temperature ranges of setting.Specific work process is as follows：
When exhaust gas temperature be more than T0 temperature ranges when, the standard-sized sheet of electric T-shaped valve 3, now boiler feed water intake by energy-saving appliance
Pipeline 6 all flows into energy-saving appliance, is flowed out after heat exchange by energy-saving appliance outlet pipeline 12, and then entered by boiler feed water pipeline 16
Boiler.
When exhaust gas temperature is in T0 temperature ranges, electric T-shaped valve 3 is automatically adjusted according to exhaust gas temperature and T0 difference
Its own aperture, now boiler feed water is a part of all flows into energy-saving appliances by energy-saving appliance inlet pipeline 6, passes through energy-conservation after heat exchange
Device outlet pipeline 12 flows out；Another part water inlet flows into branch pipe 11 without heat exchange, and this final two-way current are summarised in together, are entered
And boiler is entered by boiler feed water pipeline 16.
When exhaust gas temperature is less than T0 temperature ranges, electric T-shaped valve 3 is fully closed, and now boiler feed water all passes through branch pipe 11
Without heat exchange, and then boiler is entered by boiler feed water pipeline 16.
When energy-saving appliance breaks down can not be in use, manual-lock stop valve 4 and stop valve 10, and opening stop valve 8 makes
Boiler feed water all flows into bypass line 9, and then enters boiler by boiler feed water pipeline 16.
The effect of reducing 5 is：The resistance of electric T-shaped valve 3 is larger, may result in circulation water not enough, so for ensure into
Enter the inflow of energy-saving appliance, set reducing 5 pipeline is become big.
The effect of safety valve 15 is：When boiler feed water stays cool, now the water in energy-saving appliance is in immobilising
State, flue-gas temperature is raised with the increase of boiler load, and the water in energy-saving appliance is possible to vaporization, so that energy-saving appliance inner tube
There is potential safety hazard in road pressure rise, to solve this problem, set safety valve 15.
