Contact carries out recovery waste heat.
In addition, the inventors found that there is the slightly sour phenomenon of boiler water quality in use, proposition is specific to be solved
Scheme is as follows：
Scheme one, the weak aqua ammonia added into water after dilution
1st, the processing of chlorion
Because urban water processing adds chlorine, chlorine is dissolved in aquatic hydrochloric acid and hypochlorous acid Cl2+H2O=HCl+HClO
(reversible reaction).Acid-base reaction is carried out with the weak aqua ammonia after dilution and hypochlorous acid, hydrochloric acid：
Ammoniacal liquor and hydrochloric acid reaction generation ammonium chloride NH3·H2O+HCl=NH4Cl+H2O；
Ammoniacal liquor and hypochlorous acid reaction generation ammonium chloride NH3·H2O+HClO=NH4ClO+H2O；
Ammonium chloride is white powder or grain crystalline body, and odorless, taste are salty and carry refrigerant, easy moisture absorption caking, soluble in water,
Medical usage is extensive.
2nd, acidic treatment
Combustion product includes NO, NO2Deng nitrogen oxides, wherein：
Nitric oxide and the rapid chemical combination of oxygen, generation nitrogen dioxide 2NO+O2=2NO2；
Nitrogen dioxide is dissolved in water, generation nitric acid and nitric oxide
4NO2+O2+2H2O=4HNO3；
Acid-base reaction is carried out with the weak aqua ammonia after dilution and nitric acid：
Primary product is ammonium nitrate NH3.H2O+HNO3=NH4NO3+H2O；
Nitric oxide can also be by ammonia absorption with nitrogen dioxide, and final product is ammonium nitrate.
Ammonium nitrate is clear crystals or the crystallization of white little particle of no color or smell, there is hygroscopy.It is soluble in water.Agricultural
Upper commonly use makees chemical fertilizer.
Scheme two, into water add low concentration sodium hydrate aqueous solution, while exit install " blocking formula filter "
Sediment and other contaminant filters are come out, and are periodically rinsed to blocking formula filter.
1st, the processing of chlorion
NaOH generates sodium chloride and water NaOH+HCl=NaCl+H with hydrochloric acid reaction2O
NaOH generates sodium chloride and water NaOH+HClO=NaClO+H with hydrochloric acid reaction2O
2nd, acidic treatment
NaOH is acid-base neutralization reaction NaOH+HNO with nitric acid reaction3=NaNO3+H2O
3rd, the processing of other products
If boiler water is non-sofening treatment water, the NaOH of addition can be with the Ca in water2+、Mg2+Reaction generation Mg
(OH)2、Ca(OH)2Precipitation, blocking formula filter and can be filtered out by exit, and periodically filter carried out clear
Wash.
According to both the above program analysis it is concluded that：Utilize the weak aqua ammonia after dilution and addition NaOH water
Can be according to actual measurement water quality on the problem of solution can be very good to solve that acid and other impurities are presented in chlorion, water, consumption
Acid-base value is reasonably adjusted.Weak aqua ammonia dilute simultaneously after is colourless in normal circumstances, tasteless, non-volatile, it is ensured that
It is used safely.The sodium hydrate aqueous solution and its production concentration of low concentration are very low simultaneously, can use safely.The present invention's
The boiler water tank amount of being filled with water is few (for example：1.0T boiler water tank volumes are only 0.73 cubic metre).According to practical operation situation at 15 days
The water that left and right is changed in water tank once, so can not only remove impurity and other attached crystallized products in water tank, to boiler sheet
Body and other equipment also function to good protective effect.
In addition, the boiler suggestion of the present invention supplies system, the lesser circulation such as plate type heat exchanger, safety between supporting the use
It is stable.
Although above with general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements, belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
