Description
Technical field
The present invention relates to the treatment facility of a kind of boiler feedwater control PH, is a kind of boiler ammonifying device specifically.
Background technology
After oiler feed embrane method is processed, it is acid that water is, and pH value is lower, if such water is directly added in boiler, can cause the CO of feedwater piping and therrmodynamic system
2corrosion, need to adjust pH value to 8～9.2.Utilize the alkalescence of ammonia to neutralize residual CO
2the acidity forming, does not increase the salt of oiler feed, so ammonification is the best approach that improves oiler feed pH value.
Existing ammonification equipment is mainly directly to add ammoniacal liquor, allocating and add due to added ammoniacal liquor is to carry out not exclusively airtight in the situation that, therefore can cause adding ammoniacal liquor scene has very strong irritating smell, larger to operator's physical impairment, can cause the generation of occupational illness.
Summary of the invention
The object of the present invention is to provide a kind of boiler ammonifying device, it is to convert liquefied ammonia to ammoniacal liquor in airtight container, and nonirritant ammonia taste is overflowed, and environment and human body are not produced to harm.
Technical scheme of the present invention is as follows:
A kind of boiler ammonifying device, it is made up of ammonia pressure reducer, ammonia dissolving gauger, ammonia absorber, ammonia valve tensimeter, volume pump, pipeline, above-mentioned ammonia pressure reducer is arranged on ammonia bottle, its import and export is established tensimeter, and establish ammonia pressure reducer outlet valve, and this valve connects the ammonia inlet valve of ammonia dissolving gauger by the road, and this dissolving gauger is a tank body, its top is respectively de-mineralized water entrance, ammonia inlet, ammonia outlet; The outlet of ammoniacal liquor is established in the bottom of this tank, and this mouth is through ammonification pump intake valve, volume pump by-product water transferpump suction inlet, and another road of above-mentioned outlet is dissolved gauger wash water valve through ammonia and connected blow-off line; Ammonia dissolves gauger top ammonia outlet and connects ammonia absorber through Volatile Gas pipeline, this resorber is also a tank body, unboiled water entrance is established on its top, this mouthful of adhesion water valve, ammonia absorber ammonia row mouthful is established at top, and ammonia absorption unit is established at middle part, and visor is established in its underpart, establish ammonia absorber sewage draining exit in the bottom of ammonia absorber, this mouth is through ammonia absorber wash water valve connecting leg road.
The bottom of above-mentioned ammonia absorber is also established ammonia and is regulated relief outlet, and it connects blow-off line through ammonia absorber sewage discharging regulation valve.
The invention has the advantages that: in the working process of this ammonifying device, be 1, to convert liquefied ammonia to ammoniacal liquor in airtight container, nonirritant ammonia taste is overflowed, and environment and human body are not produced to harm, has prevented to greatest extent the generation of occupational illness.2, this device more directly adds ammoniacal liquor to reconcile oiler feed PH running cost low, and safety is easy to operate.The source of ammonia of the present invention is the liquefied ammonia of 200kg standard liquid ammonia steel bottle saving, after decompression gasification, molten water, can be made into 20% ammoniacal liquor 1000kg, can save 4/5 than the ammoniacal liquor transport charge of original use 40%.3, using ammonia pressure reducer, is that liquefied ammonia pressure in the time of gasification increases, and by the pressure≤0.1MPa of pressure reducer control steel cylinder output ammonia, makes ammonia slowly enter gauger fully soluble in water, and ensures the safety of molten ammonia.This device can be used for general boiler, cogeneration boiler and the water treatment of heat supply network supplementary feed.
