The utility model relates to machine industry, is that a kind of steam boiler of on-line operation is monitored blowdown apparatus automatically specifically.
Background technology
At present, after traditional steam boiler relies on manual sampling monitoring steam boiler water quality index, confirm blowing time and blowdown flow rate again,, can't rationally gather and in time follow the tracks of stove water change of water quality because manual sampling time, stove water discharging randomness is big, exist relative error bigger; Boiler blow-off is science, untimely not, causes in the boiler operatiopn defectively because of stove water water quality easily, causes that pot is jealous of phenomenons such as steam quality decline, fouling, priming, artifical water height, jeopardizes pot and is jealous of safe operation.
The utility model content
The online steam copper of the utility model is jealous of the purpose of automatic water quality monitoring drainage to be, provide a kind of and boiler synchronous operation, the on-line monitoring boiler water quality is realized the boiler new system of blowdown in time automatically, reach pot and be jealous of security of operation, the effect that power consumption reduces significantly.
It is to be made of drum, control instrument, sensor, electronic blowoff valve, each parts of sampler that online steam boiler water quality is monitored drainage automatically, it is characterized in that:
A) drum is provided with surperficial continuous blowdown trunk line and branch pipe(tube), branch pipe(tube) is provided with sampler, electronic blowoff valve, the delivery port of the blowoff line of electronic blowoff valve is communicated with heat exchanger, and be communicated with discharge tube behind the process heat-exchange tube, sampler is connected with control instrument by lead by sensor, and electronic blowoff valve is communicated with control instrument by lead;
B) inlet pipeline is communicated with oxygen-eliminating device by heat exchanger, perhaps directly is communicated with oxygen-eliminating device;
Heat exchanger or employing dilatation heat exchanger, heat-exchange device is established in dilatation heat exchanger bottom, and top is flash vessel, and sewage inlet is established pollutant baffle plate and fluid level controller, and steam (vapor) outlet is established at the flash vessel top, and simultaneously, flash vessel also is provided with safety valve and steam-water separator.
Electronic blowoff valve is provided with hand gear.
The beneficial effects of the utility model are:
1. guarantee that the blow-off of boiler water amount accurately is controlled in the critical field, effectively stop pot and be jealous of steam quality deterioration, gyp and corrosion, guarantee that boiler operatiopn is safe and reliable;
2. avoided artificial blowdown operation random big, the boiler operatiopn fluctuation is big, and boiler water quality changes shortcoming greatly;
3. blowdown hot water can improve feed temperature 10-15 ℃ by the feedwater of heat exchanger heating boiler, has reduced energy waste;
4. remarkable in economical benefits, the investment payback time is fast, can all recoup the investment in general 3-6 month;
5. native system is simple in structure, compact, and volume is little, and cost is lower, and is easy to install.
Description of drawings
Fig. 1, the utility model total system scheme of installation;
Fig. 2, the another kind of version schematic diagram of heat exchanger among the utility model Fig. 1 (10).
The accompanying drawing marking explanation: 1 is sampler, and 2,5 is branch pipe(tube), and 3 is sensor, and 4 is trunk line, 6 is electronic blowoff valve, and 7 is drum, and 8 is blowdown apparatus, and 9 is control instrument, 10 is heat exchanger, and 11 is oxygen-eliminating device, and 12 is water inlet pipe, 12 ' be outlet pipe, 13 are the blowdown outlet, 13 ' be the sewer inlet, 14 is flash vessel, 15 is steam (vapor) outlet, and 16 is safety valve, and 17 is fluid level controller, 18 is steam-water separator, and 19 is heat-exchange device, and 20 is pollutant baffle plate.
The specific embodiment
To structure of the present utility model and operation mechanism, further specify as follows in conjunction with the accompanying drawings:
The assembling native system.The surperficial continuous blowdown trunk line 4 of drum 7 is provided with branch pipe(tube) 2,5, and branch pipe(tube) 2 is communicated with sensor 3 by sampler 1, and sensor 3 is communicated with control instrument 9 by lead; Branch pipe(tube) 5 is communicated with control instrument 9 by lead by electronic blowoff valve 6; The blow-off line of electronic blowoff valve 6 is connected heat exchanger 10, and through after the heat exchange, by blow-off line 13 dischargings; Water inlet pipe 12 is communicated with heat exchanger 10, and the clean water of process preheating enters oxygen-eliminating device 11.Heat exchanger 10 or employing dilatation heat exchanger, its bottom is provided with heat-exchange device 19, and top is provided with flash vessel, sewer inlet 13 ' be provided with pollutant baffle plate 20 and fluid level controller 17, the flash vessel top is provided with steam (vapor) outlet 15, and simultaneously, flash vessel also is provided with safety valve 16 and steam-water separator 18; Electronic blowoff valve 6 also is provided with hand gear.
As shown in Figure 1, the utility model is according to conductivity signal in the stove water, and the salt content of following the tracks of water changes, and fast the correlation values feedback is passed to control instrument.In advance according to boiler water quality and boiler water quality standard, setting device control corresponding scope and data are receiving the correlation values that conductivity sensor 3 transmits, and instruct electronic blowoff valve to start timely and accurately according to Monitoring Data and close electronic blowoff valve blowdown; When rising-surpass, electrical conductivity sets value electronic blowoff valve unlatching-beginning blowdown; When electrical conductivity descends-is lower than when setting value, electronic blowoff valve cuts out-and blowdown stops, and realizes steam boiler on-line operation automatic pollution discharge function.
