Specific embodiment
Embodiment 1:
As depicted in figs. 1 and 2, Leachate site is lifted out through submersible sewage pump (2) pressurization by strainer (1) filtered Leachate site
Pond.Leachate site enters Leachate site surge tank (4) after the self-cleaning filter (3) being arranged in pipeline carries out secondary filter.From
Filter (3) are cleaned individually to control, can temporally cycle set self-cleaning program, can also be according to self-cleaning filter internal screen
Front and back pressure difference carry out individual filter gauze cleaning control.Sewage in cleaning process is backflowed again into Leachate site pond.Leachate site warp
Entering in Leachate site surge tank (4) after crossing the secondary filter of self-cleaning filter, Leachate site surge tank top is provided with overflow port,
After Leachate site is more than overflow port, Leachate site meeting automatic overflow bleeds back drip liquid pool, fills and is equipped with liquidometer (5) on body, to control
Automatic control of the cabinet processed to whole system.Leachate site surge tank lower part is provided with sewage draining exit, drips by the infiltration of self-cleaning filter
Still contain tiny particle sediment in liquid, these sediments by the sewage draining exit of surge tank lower part, by electrical ball valve (6) and
Periodically surge tank is discharged in sediment in Leachate site surge tank by the opening and closing of dredge pump (7), flows back into Leachate site pond.
The exit of Leachate site surge tank has pipeline connection to booster pump (8), is delayed Leachate site by the pressurization of booster pump
The Leachate site rushed in tank is pressed and delivered to boiler room, and boiler wall is open, and big channel atomizing lance (11) is fixed on furnace
Thorax high-temperature area.Leachate site after pressurization be directly entered after filter (10) filter three times big channel atomizing lance into
Row atomization, atomizing medium are atomized using compressed air.The pneumatic control valve (9) of feedback is provided on compressed air hose road,
Big channel atomizing lance import compressed air require is adjusted, when system is without being atomized back spray, can suitably keep one
Fixed control valve opening, cools down atomizing lance, avoids big channel atomizing lance pipette tips scaling loss.
By pressurization, compressed air atomization Leachate site, short grained liquid-drop diameter and big channel atomizing lance design
Flow is related, differs at 60-120 microns.Under high temperature environment, the droplet after atomization is in extremely short time (being less than 1S) and spray
It penetrates apart from interior suction thermal evaporation.After pervaporation, the organic matter in Leachate site is incinerated totally at high temperature, inorganic in Leachate site
Salt and heavy metal are attached on flying dust, itself contains a large amount of inorganic salts and heavy metal in flying dust, and flying dust is captured by deduster, into
And carry out curing process.Thus the present invention is that water and noxious pollutant have been carried out necessary point using the high temperature in boiler furnace
From having achieved the purpose that Leachate site reduction process expense zero-emission, great economic utility and environmentally friendly effectiveness.In addition, the system is not only
Only Leachate site is handled in burning power plant, to the same system of desulfurization wastewater after the wet desulphurization in thermal power plant
It can be handled.In addition, waste oil directly by big channel atomizing lance (11), is changed to atomized oil gun, can directly be handled useless
Oil.
Every spray gun atomized liquid maximum stream flow is 1.25m3/h.Compressed air is provided by air compression station total in field,
0.5~0.6MPa of pressure.Spray gun pipette tips are fabricated using the Ni-based highly corrosion resistant alloy processing of Hastelloy+coating processing, are sprayed
Gun barrel road uses corrosion-resistant 316L stainless steel tube.
Sewage pump design discharge 3t/h, 30 meters of lift.Self-cleaning filter uses brush type self-cleaning filter.Work as filter
When the pressure difference of inlet and outlet reaches preset value (0.5bar) or time setting value, filter will start self-cleaning: open blowdown valve, electricity
Machine drives cleaning brush rotation.Entire cleaning process time-consuming 15-30 seconds, system does not stop when cleaning, the whole service of filter
Journey is controlled by a control cabinet being equipped at random.
2 effect experiment of embodiment
Certain garbage incinerating power plant is designed as the fire grate type waste incinerator of day output 400T/D, enters furnace material in burner hearth
Enter waste heat boiler after interior carry out high-temp combustion.Flue gas purification system is removed using semidry method+active carbon/lime injection+pocket type
The purification process that dirt device is combined.Leachate site returns spray system list furnace and is designed as 2.5T/H, and 2 incinerators design 4 rifles, and single hour
Total treating capacity is 5T/H.
The system design parameters are as follows:
| Serial number | Title | Unit | Parameter |
| 1 | Return spray evaporation capacity | T/H | 5 |
| 2 | Atomization air pressure | MPA | 0.35 |
| 3 | Leachate site outlet pressure | MPA | 0.35 |
| 4 | Leachate site atomized particle size | Micron | 90 |
| 5 | Drop evaporation time | Second | 0.35 |
| 6 | Evaporate distance | Rice | 3 |
Economy is analyzed as follows after returning spray system using Leachate site:
Project original design has the processing of hosted-type Leachate site station, and processing cost per ton is 50 yuan/T.Spray is returned by Leachate site
It is as follows that system evaporation technique handles economy:
5T/H × 24H=120T (the daily Leachate site of 2 furnaces returns spray evaporation treatment capacity)；
120T × 50 yuan/T=6000 is first (daily direct saving leachate treatment takes)；
System power consumption statistics (being atomized using compressed air) is as follows:
System power consumption is about are as follows: 90KW；(main power consumption is air compressor machine)；
Waste incineration and generating electricity mark post rate for incorporation into the power network: 0.65 yuan/kw；
90KW × for 24 hours × 0.65 yuan/kwh=1404 is first (electricity charge are lost daily)；
Leachate site returns spray net saving handling daily are as follows:
6000 yuan/D-1404 member/D=4596 member/D；
1 year direct saving expense are as follows:
4596 yuan/T × 365 × 90% (year availability)=150.98 ten thousand yuan/year；
Note: only Leachate site time spray is brought this income.Because of the reduction of heating surface inlet temperature, the increasing of single hour garbage treatment quantity
Add and the brings economy such as pollutant reduces are also more considerable.
