Background technology
At present, though the water-supply source of industrial boilers in China is through sodium ion exchange treatment technology (being commonly referred to as " deionized water "), but in boiler running process, because the fierceness of high steam and furnace wall or duct wall bump, to there be a large amount of metal ions (as: iron ion) to enter water supply system, and cause stove water salt content higher with steam.In order to ensure the safe operation of boiler, must strengthen blowdown flow rate, blowdown rate reaches 10～37% more than sometimes.Platoon waste-heat recovery device has originally just been installed a blowdown system, after the dilatation of platoon water process flash vessel, has produced a large amount of flash steams, to atmosphere, has both polluted environment by exhaust-valve row, has caused the heat loss again.Meanwhile, a large amount of platoon water more than 100 ℃ are drained by sewage well, have also caused the very big energy waste and the thermal pollution of environment.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of Industrial Boiler continuous blowdown energy saver is provided, separates and " water-water " heat exchange,, rationally utilize waste heat to improve the feed temperature in the water softening tank by " vapour-water ", and energy-saving and cost-reducing.
In order to solve the problems of the technologies described above, the utility model comprises flash steam outlet, Pressure gauge, vapour-water separation tank, orifice flowmeter, U-shaped pipe, stainless steel pollutant baffle plate, electromagnetism fluid level control valve, heat exchanger coil, water-water heat exchange jar, soft water import, soft water outlet and safety valve, described vapour-water separation tank is above water-water heat exchange jar, and vapour-water separation tank and water-water heat exchange jar is communicated with by the electromagnetism fluid level control valve.
Described vapour-water separation tank top is equipped with flash steam outlet, Pressure gauge and safety valve, and vapour-water separation tank sidewall is welded with the U-shaped pipe that communicates with vapour-water separation tank, and the U-shaped pipe is welded with the stainless steel pollutant baffle plate in the exit of vapour-water separation tank inwall.
1～6 orifice flowmeter is installed on the described U-shaped pipe.
Described water-water heat exchange jar inner chamber is equipped with heat exchanger coil, and the two ends of heat exchanger coil communicate with soft water import and soft water outlet respectively; Soft water import and soft water outlet are welded on respectively on the sidewall of water-water heat exchange jar, and the soft water import is below soft water outlet; Another electromagnetism fluid level control valve that is used for blowdown is installed in the bottom of water-water heat exchange jar.
The beneficial effects of the utility model: 1, the heat energy of recyclable continuous blowdown water 90%; 2, fuel saving, cooling water and make-up water are accelerated investment repayment; 3, reduce environmental thermal pollution, blowdown thing centralized collection such as incrustation scale are handled; 4, can bear high load capacity, uninterrupted operation continuously fully.

The specific embodiment
A kind of specific embodiment as shown in Figure 1, it comprises flash steam outlet 1, Pressure gauge 2, vapour-water separation tank 3, liquid level calibration gauge 4, orifice flowmeter 5, U-shaped pipe 6, stainless steel pollutant baffle plate 7, electromagnetism fluid level control valve 8, heat exchanger coil 9, water-water heat exchange jar 10, soft water import 12, soft water outlet 13 and safety valve 14, described vapour-water separation tank 3 is above water-water heat exchange jar 10, and vapour-water separation tank 3 and water-water heat exchange jar 10 is communicated with by electromagnetism fluid level control valve 8.Vapour-water separation tank 3 tops are equipped with flash steam outlet 1, Pressure gauge 2 and safety valve 14, and vapour-water separation tank 3 sidewalls are welded with the U-shaped pipe 6 that communicates with vapour-water separation tank 3, and U-shaped pipe 6 is welded with stainless steel pollutant baffle plate 7 in the exit of vapour-water separation tank 3 inwalls.1～6 orifice flowmeter 5 is installed on the U-shaped pipe 6.Water-water heat exchange jar 10 inner chambers are equipped with heat exchanger coil 9, and the two ends of heat exchanger coil 9 communicate with soft water import 12 and soft water outlet 13 respectively; Soft water import 12 and soft water outlet 13 are welded on respectively on the sidewall of water-water heat exchange jar 10, and soft water import 12 is below soft water outlet 13; Bottom at water-water heat exchange jar 10 is equipped with the electromagnetism fluid level control valve 11 that is used for blowdown.
Workflow:
As shown in Figure 1, the blowdown steam that comes out from the continuous blowdown system of boiler valve passes through orifice flowmeter 5 air inlets, enters the filter chamber of flowmeter.At this, the solid suspension that carries in the steam is stopped and is precipitated that the flow velocity of blowdown steam can be regulated by the gear on the orifice flowmeter 5, and has scale to show.The draining flushing valve is equipped with in the below of stainless steel filter chamber, the valve of can regularly outwarding winding, and accumulation precipitation dirt sweeps away from discharge outlet immediately.The flow-control of boiler continuous drainage (sewer) can make the reasonable blowdown of boiler, improves energy-saving effect.
The blowdown steam of access arrangement main body---vapour-water separation tank 3 is subjected to stopping of stainless steel pollutant baffle plate 7, and solid suspension dirt is wherein hindered again and precipitates, and enters vapour-water separation tank 3 bottoms by the continuous-flow of deadweight, with cleaning systems inside.
Hot water in the jar after " vapour-water " separates reaches when setting liquid level, and electromagnetism fluid level control valve 8 is opened automatically, and the hot water in vapour-water separation tank 3 enters the water-water heat exchange jar 10 of below.Demineralized water enters from soft water import 12, after heat exchanger coil 9 heat exchanges, flows out from soft water outlet 13, delivers to the hot well of feed water system of boiler heater, reaches the effect of waste heat recovery.In case the steam pressure overload, vapour-water separation tank 3 tops have been installed safety valve 14 and have just been opened automatically.
When the sewage in water-water heat exchange jar 10 reached the setting liquid level, electromagnetism fluid level control valve 11 was opened, and sewage is discharged.
