background technology
Boiler is in running, along with the evaporation of moisture, various impurity in water are constantly concentrated in drum, in order to ensure the normal operation of boiler, need by the mode control concentration rate of continuous blowdown, the boiler water that continuous blowdown is discharged is generally the saturation water under relevant pressure, contain a large amount of heat energy, if medium temperature and medium pressure boiler blowdown water enthalpy is 1087kJ/kG, high-temperature high-pressure boiler sewer enthalpy is 1408kJ/kG, and subcritical boiler sewer enthalpy is up to 1700kJ/kG.Continuous blowdown not only loses a large amount of heat energy, and therefore waste fuel, also may cause thermal pollution and noise; The steam generator system of most steam power plant has adopted platoon flash vessel, flash-off steam is that oxygen-eliminating device is used, can get back to partial heat energy and working medium, but platoon flash vessel cannot be cooled to sewer below 100 DEG C, for adopting the system of higher-pressure deaerator, platoon flash vessel water outlet enthalpy is still up to 600-700kJ/kG, and (temperature is 140-180 DEG C), the heat of recovery is limited.
utility model content
For overcoming the problems referred to above, solution deaerating effect is poor, pipeline is complicated, cannot regulate the problem of the deoxygenation water yield, and the technical solution adopted in the utility model is as follows:
A kind of Novel connection exhaust heat reclamation device, comprise boiler platoon water water inlet, boiler platoon water water inlet is connected with platoon flash vessel, platoon flash vessel top is provided with oxygen-eliminating device, platoon flash vessel side and bottom are respectively equipped with pipeline, pipeline is also connected with upper and lower two pipelines, on two pipelines, be respectively equipped with valve, pipeline is connected with top set's structure of pipeline, the other end pipeline of the pipeline being up and down connected with pipeline is connected with sewer water intaking valve and sewer bypass valve by pipeline respectively, the sewer water intaking valve other end is received and can be communicated with at device top with platoon, platoon is received and can be connected with sewer outlet valve by pipeline at device other end top, the sewer outlet valve other end respectively by pipeline with sewer bypass valve with surely arrange flash vessel and be connected, platoon is received and can be communicated with cooling water water intaking valve and cooling water outlet valve by pipeline respectively both sides, device top, cooling water water intaking valve and cooling water outlet valve respectively with pipeline communication, pipeline is provided with cooling water bypass valve, and platoon is received and can be provided with receipts energy device discharging valve in device bottom.
Surely arrange flash vessel bottom and be provided with valve.
Two, the pipeline that pipeline bottom connects is equipped with valve.
Advantage of the present utility model: it is large that this device has the coefficient of heat transfer, compact conformation, shape is regular, easy for installation, and the water quality after recovery is good.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
detailed description of the invention
Below in conjunction with accompanying drawing, to this novel its detailed description of the invention that further illustrates:
As shown in Figure 1, a kind of Novel connection exhaust heat reclamation device, comprise boiler platoon water water inlet 1, boiler platoon water water inlet 1 is connected with platoon flash vessel 2, platoon flash vessel 2 tops are provided with oxygen-eliminating device 3, platoon flash vessel 2 sides and bottom are respectively equipped with pipeline 4-1, pipeline 4-2, pipeline 4-2 is also connected with upper and lower two pipelines, on two pipelines, be respectively equipped with valve, pipeline 4-1 is connected with top set's structure of pipeline 4-2, the other end pipeline 4-3 of the pipeline being up and down connected with pipeline 4-2 is connected with sewer water intaking valve 5 and sewer bypass valve 6 by pipeline respectively, sewer water intaking valve 5 other ends are received and can be communicated with at device 7 tops with platoon, platoon is received and can be connected with sewer outlet valve 8 by pipeline at device 7 other end tops, sewer outlet valve 8 other ends respectively by pipeline with sewer bypass valve 6 with surely arrange flash vessel 9 and be connected, platoon is received and can be communicated with cooling water water intaking valve 10 and cooling water outlet valve 11 by pipeline respectively device 7 both sides, top, cooling water water intaking valve 10 and cooling water outlet valve 11 are communicated with pipeline 4-4 respectively, pipeline 4-4 is provided with cooling water bypass valve 12, and platoon is received and can be provided with receipts energy device discharging valve 13 in device 7 bottoms.
Surely arrange flash vessel 9 bottoms and be provided with valve, facilitate effluent sewerage.
Two, the pipeline that pipeline 4-1 bottom connects is equipped with valve.
When work:
2. open cooling sea water outlet valve, slowly closing cooling water bypass valve, checks that whether cooling water is unimpeded.
3. slowly open sewer inlet valve, check whether weld bond leaks, and whether has abnormal sound or vibrations.
4. slowly open sewer outlet valve, turn down sewer bypass valve, until complete shut-down is adjusted sewer outlet valve aperture, make platoon flash vessel maintain ordinary water level, and blow-off line non-water-attack.
5. must first open sewer inlet valve, with outlet valve adjustment sewer flow.
6. when sewer outlet valve aperture is excessive, pipeline pressure is too low, sewer will produce indirect steam, cause Pipeline Water Hammer, vibrations and erosion, now can suitably turn down sewer outlet valve or after sewer outlet valve, install suitable restricting orifice additional, suitably improve pressure, alleviate or eliminate water attack and vibrations.
