Contact carries out recovery waste heat.
In addition, utility model people of the present utility model has found the slightly sour phenomenon of boiler water quality in use be present, propose
Specific solution 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, odorless, taste it is salty and with refrigerant, easy moisture absorption caking, it is 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, generates 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
Sodium hydroxide and hydrochloric acid reaction generation sodium chloride and water NaOH+HCl=NaCl+H2O
Sodium hydroxide and hydrochloric acid reaction generation sodium chloride and water NaOH+HClO=NaClO+H2O
2nd, acidic treatment
Sodium hydroxide and nitric acid reaction are acid-base neutralization reaction NaOH+HNO3=NaNO3+H2O
3rd, the processing of other products
If boiler water is non-sofening treatment water, the sodium hydroxide 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 is carried out clear
Wash.
According to both the above program analysis it is concluded that：Using the weak aqua ammonia after dilution and add sodium hydroxide water
Solution can be very good to solve the problems, such as presentation acidity and other impurities in chlorion, water, can be according to actual measurement water quality in dosage
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 of low concentration and its production concentration are very low simultaneously, can use safely.This practicality is new
The boiler water tank amount of being filled with water of type it is few (such as：1.0T boiler water tank volumes are only 0.73 cubic metre).Existed according to practical operation situation
15 days or so the water changed in water tank once, so can not only remove impurity and other attached crystallized products in water tank, to pot
Furnace body and other equipment also function to good protective effect.
In addition, boiler suggestion of the present utility model supplies system, such as the lesser circulation such as plate type heat exchanger between supporting the use,
Safety and stability.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will
Seek the scope of protection.
