The using method of the present embodiment device is: from each boiler-steam dome out 312 DEG C, the HTHP blowdown water of 10.3MPa connects by blowdown the boiler blow-off waste water water inlet pipe 3 that female pipe enters the compensation dilatation purification recovery device of enthalpy difference, then enters in hybrid filtering tank 1, 280 DEG C, 0.98MPa working steam (directly can utilize the steam in low pressure heating steam pipe network) after working steam steam inlet pipe 4 with 312 DEG C, the HTHP blowdown water of 10.3MPa carries out step-down in venturi-type eductors 5, dilatation, vaporization are carried out mixing and enthalpy difference fully and compensated, wherein 312 DEG C, during the entering of the HTHP blowdown water of 10.3MPa and working steam, initial flow is than being 1:(5-20), namely carry out coagulation to improve flow velocity, reduce pressure, sufficient steam-water mixing obtains sufficient enthalpy difference and compensates and then make liquid waste water be converted to the saturated of low pressure or superheated steam state, boiler blow-off waste water vapor, enter after the anemostat of venturi-type eductors 5 after mixing enthalpy difference compensates and block absorption filter element 6 that filter tentatively filters amino composite nano materials and carry out secondary super large dilatation step-down and filter, the effect that secondary blocks filter mainly reduces steam flow rate, stop vaporization precipitate, silica, calcium ions and magnesium ions deposit etc. is taken out of with steam, run precipitate after a period of time to adhere to gradually and be accumulated on filter core, pressure reduction before and after filter core can be caused to increase, after before and after filter core, pressure reduction reaches setting pressure reduction, by supplementing water pipe, backwash is carried out to filter core with cleaning supplementary water, precipitate is fully dissolved and is got rid of by the sewage draining exit 19 bottom hybrid filtering tank 1 again.(before and after filter screen pressure differential resetting alarming value access PLC) is then through entering the three-level filter system in precise filtering tank 2 tank cavity communicating pipe 7, the effect of three-level filter system is mainly by high-new scavenging material and technology---the absorption filter element made by amino composite nano materials, to to be separated out by steam and the sodium ascorbyl phosphate ion brought out carries out last absorption, precipitate, got rid of (the same) by the sewage draining exit 19 bottom precise filtering tank 2 again by washing precipitate fully to dissolve to filter-core back-flushing by supplementing water, steam is discharged finally by the steam outlet pipe 9 of precise filtering tank 2.When detect from steam outlet pipe 9 discharge vapor (steam) temperature pressure lower than setting value time, by regulating the valve of the admission electric control valve on hybrid filtering tank 1 end cap portions working steam steam inlet pipe 4, regulate and control the throttle flow of working steam steam inlet pipe 4 input service steam, increase working steam amount to improve the final heat enthalpy value exporting steam, the low-pressure saturated steam heated in tank body increases enthalpy difference compensation rate, and then makes the vapor (steam) temperature force value of output meet the requirement of lower road technique.The described absorption filter element made by amino composite nano materials, it reaches as high as 85-97% to Phosphate Adsorption rate.
The present embodiment recovery boiler blowdown water volume energy saving profit is settled accounts:
A boiler reclaims the calculating of blowdown water by minimum blowdown rate 2%
The boiler of 1 boiler capacity 240 tons/hour, boiler blow-off water pressure 10.3MPa, temperature 312 DEG C, by the blowdown rate of the minimum evaporation capacity 2% of boiler, boiler wastewater discharges 4.8 tons of/hour high-grade used heat.Be incorporated to heat supply network (pressure 0.98MPa, temperature 280 DEG C) again after the hot grade of raising after being compensated its filtration, vaporization, heating enthalpy difference by working steam, its hot grade is equivalent to the calorific value of heating steam, can produce very considerable economic benefit after recovery.But this boiler wastewater of 4.8 tons/hour originally had and reclaimed the heat of a part of flash-off steam by platoon flash vessel, yield was about 24%, so the economic benefit that this heat of 24% that this recovery system should deduct original oxygen-eliminating device produces.
Energy valuation benchmark:
Heating steam pressure 0.98Mpa temperature 280 DEG C, steam calorific value is pressed: 70.3 × 10
4kcal/ ton; Steam price 150 yuan/ton accounting, runs clearing in 8000 hours per year:
Steam Recovery benefit can be produced: the economic benefit of the boiler blow-off waste heat generation of recovery: ton/hour × the 8000 hours × 150 yuan × 76%(former platoon flash vessel rate of recovery is 24%)=437.76 ten thousand yuan,
Indirect recovery benefit: reclaim water for industrial use 28800 tons X6 yuan/ton=17.2 ten thousand yuan,
Year energy-conservation total revenue: sewer reclaims the indirect benefit 170,000 yuan=4,540,000 yuan of benefit 4,370,000 yuan+recycle-water.
To sum up, blowdown water after dilatation, vaporization, absorption, filtration, purification, is changed into low-pressure saturated steam or superheated steam, then is incorporated to heat supply webmaster by a kind of boiler blow-off waste water boiler blowdown water enthalpy difference compensation dilatation purification recovery device of the present embodiment; When the setting value of temperature lower than heat supply webmaster, enthalpy difference compensation can also be carried out by hot operation steam, reach the output steam with heat supply network corresponding temperature, thus the maximized recycling of the used heat accomplished, accomplish that Waste Heat Recovery utilization rate reaches more than 98.5%, thoroughly solve boiler blow-off loss problem; And whole apparatus structure is simple, easy to operate and cost is low.
