Description
Technical field
The invention belongs to acid mist processing technology field, it is specifically related to a kind of Acid mist treatment method.
Background technology
Sulfuric acid mist mainly exists in an atmosphere in the form of an aerosol, and traditional processing method is the washing including wet type
Method, alkali liquid washing send out and the silk screen filter method of dry type, active carbon adsorption, electrostatic precipitator demisting method, also useful suspension plastics
The method preventing and treating acid fog outflows such as ball covers, foam closing liquid level, but these method efficiency are low, also do not reach the mesh purifying acid mist
, comparatively, wet purification method water consumption is big, it is also easy to produce secondary pollution, operating cost is high, floor space is big, these methods
Processing procedure very complicated, treatment effeciency is low.
Content of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides a kind of Acid mist treatment method, acid mist
Treatment effeciency is high, acid mist treatment effect is good.
Technical scheme: for achieving the above object, a kind of Acid mist treatment method of the present invention, a kind of acid mist processing system is provided
System, this acid mist processing system includes circulating slot that absorption tower connect with described absorption tower bottom, is placed in that described absorption tower is internal to push up
The shower at end and described absorption tower side by the descaling bath of pipeline communication, be placed in the enclosed hood at described descaling bath top with
And be placed in antiseptic ventilator between described descaling bath and absorption tower, described absorption top of tower is provided with outlet, described circulating slot and
Connected by pipeline between shower within described absorption tower, between the shower within described circulating slot and described absorption tower
It is provided with solution pump, in described circulating slot, be provided with alkali liquor；
The method comprising the steps of:
S1 acid mist initially enters in described descaling bath, and the exhaust outlet then setting on the enclosed hood top at described descaling bath top is arranged
Go out；
The subsequent acid mist of s2 enters described absorption tower bottom lower end hence into described absorption in the presence of described antiseptic ventilator
In tower；
The outlet from described absorption tower top for a small amount of sodium hydroxide solution is entered inside described absorption tower by s3 simultaneously, then from
Described shower sprays downwards, and sodium hydroxide solution and acid mist are reacted, and reaction equation is:
naoh+so2+h2o=nahso3；
The sodium hydroxide solution that s4 absorbs acid mist flows in described circulating slot by pipeline, mixed solution in described circulating slot
In the shower entering described absorption tower inner tip under described solution pumping action, again occur anti-with the new acid mist entering
Should.
Further, described enclosed hood adopts fiberglass enclosed hood.
Further, it is provided with electrostatic control means in described enclosed hood.
Beneficial effect: compared with the prior art, method proposed by the present invention processes acid mist efficiency high to the present invention, processes acid mist
Effect is good.
Brief description
Fig. 1 is acid mist processing system structural representation proposed by the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further described.
Embodiment:
As shown in figure 1, a kind of Acid mist treatment method proposed by the present invention, provide a kind of acid mist processing system, this acid mist processing system
System include absorption tower 1 with the described absorption tower 1 bottom circulating slot 2 connecting, the shower that is placed in described absorption tower 1 inner tip
3 with described absorption tower 1 side by the descaling bath 4 of pipeline communication, be placed in the enclosed hood 5 at described descaling bath 4 top and be placed in
Antiseptic ventilator 6 between described descaling bath 4 and absorption tower 1, described absorption tower 1 top is provided with outlet 7, described circulating slot 2 He
Connected by pipeline between shower 3 within described absorption tower 1, the shower within described circulating slot 2 and described absorption tower 1
It is provided with solution pump 8 between 3, in described circulating slot 2, be provided with alkali liquor；
The method comprising the steps of:
S1 acid mist initially enters in described descaling bath 4, the exhaust outlet then setting on enclosed hood 5 top at described descaling bath 4 top
Discharge；
The subsequent acid mist of s2 enters described absorption tower 1 bottom lower end hence into described suction in the presence of described antiseptic ventilator 6
Receive in tower 1；
By a small amount of sodium hydroxide solution, the outlet 7 from described absorption tower 1 top enters inside described absorption tower 1, then s3 simultaneously
Spray downwards from described shower 3, sodium hydroxide solution and acid mist reacted, reaction equation is:
naoh+so2+h2o=nahso3；
The sodium hydroxide solution that s4 absorbs acid mist is flowed in described circulating slot 2 by pipeline, mixes molten in described circulating slot 2
