Summary of the invention
The purpose of this utility model is to provide a kind of vapourizing furnace usage on black water device, be conducive to reducing hardness and suspended substance in vapourizing furnace Heisui River, thus make treated water reach reuse standard, or the water energy fully recovering after advanced treatment, realize the target of zero release.
In order to reach above object, the utility model have employed following technical scheme:
Equalizing tank is connected with one end of lift pump, the lift pump the other end is connected the dry slag equipment of automatic back-washing surface filter, automatic back-washing surface filter dry slag equipment configuration blower fan, the dry slag device bottom of automatic back-washing surface filter is equipped with the outer shipping unit of filter residue, anti-interference water treating device is connected with after automatic back-washing surface filter dry slag equipment, molten solid/liquid/gas reactions device is connect after anti-interference water treating device, molten solid/liquid/gas reactions device is equipped with carbon dioxide storage tank, dashpot is provided with bottom molten solid/liquid/gas reactions device, be connected with dashpot and be connected to liquid feeding pump, another termination automatic back-washing surface filter of liquid feeding pump.
All parts is connected by pipeline, and pipeline enclosure arranges valve.
Slag slurry reflux line is set bottom automatic back-washing surface filter to equalizing tank.
Compared with prior art, the utility model has following advantage:
1) flow process is simple, and facility investment expense is low, floor space is little.
2) running cost is low, mainly makes with medicament be carbon dioxide, also directly can utilize power plant flue gas, reach the object realizing the treatment of wastes with processes of wastes against one another.
3) pressure air-dissolving reactor makes gas better dissolve in liquid under pressure, both realized gas-liquid and effectively, fully mixed, and reduces again the waste that gas causes because of spilling.
4) wherein anti-interference water treating device is the liquid processor of a kind of environmental protection, high-efficient and lasting.It, by radioprotective, Anti-Jamming Technique and the perfect adaptation of closed energy loop technique, plays scale inhibition/scale removal, inhibition, sterilization algae removal, the effect of crystallization-preventive.
5) waste water after the process of technique employing automatic back-washing surface filter equipment direct filtration, because filter area is wide, filtering accuracy is high, working cost is low, level of automation is high, floor space is little, there is again acid-and base-resisting, brine corrosion function, the most important thing is to reduce the suspended substance in water quality, reduce the material easily causing fouling, reach the effect of scale inhibition.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
First vapourizing furnace Heisui River enter the dry slag equipment configuration of automatic back-washing surface filter, and the dry slag after filtration directly transports outward process; Clear liquid after filtration enters the pipeline increasing anti-interference water treating device, to prevent pipeline scale crystallization, and then in clear liquid, pass into the hardness (adopting the molten solid/liquid/gas reactions device of carbonic acid gas) that carbonic acid gas is used for reducing in water, and then enter self-stip surface filter and filter, after filtering, clear liquid can be back to the operating mode or qualified discharge that adapt, filter residue slurry is got back to the dry slag equipment of automatic back-washing surface filter and is filtered together with vapourizing furnace Heisui River, finally reaches the target of zero release.The molten solid/liquid/gas reactions device adopted in this device will pass into the carbonic acid gas in carbon dioxide storage tank in the lump in molten solid/liquid/gas reactions device while waste water enters wherein, and carbonic acid gas is fully mixed with waste water.Clear water direct reuse after automatic back-washing surface filter filters is in the operating mode used, and filter residue is back to equalizing tank and again processes.
