Described disc type steam-water injection bottom is provided with water-level gauge.
Described drain pipe is connected to oxygen-eliminating device top after converging with the demineralized water inlet valve that flowmeter is housed.
The described water level that is positioned at disc type steam-water injection bottom is counted the fluid level transmitter being connected with intelligent display controller.
The utility model adopts trickle disc type steam-water injection, demineralized water enters hybrid heater, after steam discharge absorption is mixed, heats, and in heating process, noncondensing gas is discharged by top automatic exhaust valve, hot water flows out to water tank from bottom, with variable frequency pump, squeezes into oxygen-eliminating device.This process reclaims in heater device and remains certain liquid level, to guarantee to reclaim in heater, has stable pressure, and not condensing body is discharged fully, reclaims the work that heater can be stable.Liquid level by fluid level transmitter signal transmission to intelligent display instrument control system.Reclaim hybrid heater and moisturizing temperature can be increased to 50 ℃～60 ℃, can heat moisturizing and make full use of exhaust steam.Thereby the moisturizing temperature that has improved oxygen-eliminating device is also equivalent to save the steam turbine steam consumption and is also equivalent to save raw coal.
1, reclaiming steam discharge calculates:
0.8t/h * 8000h/ * 80 yuan/ten thousand yuan of t=51.2
Remarks: separate unit steam discharge is about 0.8t/h, 80 yuan/t(of steam price estimates) whole year operation press 8000h/ calculating.
2, reclaiming condensed water calculates:
0.8t/h * 8000h/ * 5 yuan/ten thousand yuan/year of t=3.2
Remarks: condensed water calculates by 5 yuan/t, operation is pressed 8000h/ and is calculated.
3, the consumption that increases electric power: 8KW calculates by pump name plate rating (maximum estimation)
8KW * 0.4 yuan/ten thousand yuan/year of KWh * 8000h/=2.56
Remarks: station service is by 0.4 yuan/degree
4, maintenance expense: estimate for 1.5 ten thousand/year
5, year saving:
Ten thousand yuan of (increase power consumption) ten thousand yuan/year of-1.5 ten thousand yuan of (maintenance expense)=50.34, yuan (condensed water)-2.56,51.2 ten thousand yuan of (steam discharge)+3.2 ten thousand (separate unit oxygen-eliminating device)
It is cost-saving that separate unit oxygen-eliminating device is equivalent to day: 50.34 ten thousand yuan of ÷ 333=1512 units
According to calculating less than half a year with regard to recyclable investment.
Correctional effect
1. to have volume little for steam-water mixture heater product, and price is honest and clean, small investment.Well below domestic surface heater investment.
2. organic efficiency is high, demineralized water temperature rise can be improved to 50～60 degree, recovered steam utilization rate 100%.
3. advanced technology vibrations are little, and noise is low.
4. simple in structure, less scaling, non-maintaining, long service life.
5. save the energy, protected environment.
6. operate steadily and all meet indices requirement.
