Description
Technical field
It the utility model is related to concentrated water processing technology field, more particularly to a kind of reverse osmosis concentrated water utilization system.
Background technology
Cooling and steam supply in steam power plant's power generation process are required for using pure water, and dosage is bigger, and pure water produced
Cheng Zhonghui produces many concentrated waters, and the salt content of concentrated water is about 4-5 times of raw water, is handled, is caused very usually as waste water
The big wasting of resources.
By taking certain steam power plant as an example, the leading indicator contrast of concentrated water and raw water is as follows：
| Lab work | Raw water | Reverse osmosis concentrated water |
| PH | 7.36 | 9.05 |
| Full basicity (mg/L) | 189 | 758 |
| Ca+2(mg/L) | 86.9 | 298 |
| HCO3-(mg/L) | 132 | 516 |
Contrasted by above index, it is found that the alkaline index of reverse osmosis concentrated water is especially high, if directly discharged or as green
Change, cleaning sanitary water can cause discharge beyond standards, cause environmental pollution.At the same time, the basicity of reverse osmosis concentrated water is high, with boiler
The alkaline slurry that wet desulphurization needs is identical, can use water as boiler wet method desulfurization.
The principle of wet desulphurization, be calcium oxide add water be mixed into limewash after (calcium hydroxide is in alkalescence) by sprinkling with
Sulfur dioxide after coal-fired or other fuel combustions generates calcium sulfite and water and a small amount of calcium sulfate, its root after fully reacting
Present principles are exactly acid-base neutralization reaction.
Chemical reaction formula therein：
Absorb：SO2(g)→SO2(l)+H2O→H++HSO3-→H++SO3 2-
Dissolving：Ca(OH)2(s)→Ca2++2OH-
CaSO3(s)→Ca2++SO3 2-
Neutralize：OH-+H+→H2O
OH-+HSO3 -→SO3 2-+H2O
Oxidation：HSO3 -+1/2O2→SO3 2-+H+
SO3 2-+1/2O2→SO4 2-
Crystallization：Ca2++SO3 2-+1/2H2O→CaSO3·1/2H2O(s)
Ca2++SO4 2-+2H2O→CaSO4·2H2O(s)
Desulfurization principle more than can be seen that PH, basicity, Ca ions, the HCO3 of reverse osmosis concentrated water-Exactly boiler is wet
What method desulfurization needed, the sulfurous acid of water formation is met using the sulfur dioxide in the high alkalinity of reverse osmosis concentrated water and in boiler smoke,
It can reach desulfurization, reduce dosage, the purpose to cut operating costs of desulfurizing agent.
