Equal to I-shaped section 6 pipe diameter；
The opening that the opening diameter of the downwardly open funnel of Large Diameter Pipeline section 9 is same as I-shaped section upward opening funnel 10 is straight
Footpath, the downwardly open funnel of Large Diameter Pipeline section 9 becomes anti-alkali liquor refluence liquid storage with the closure of openings of I-shaped section upward opening funnel 10
Room 12, the above of anti-alkali liquor refluence fluid reservoir 12 is Large Diameter Pipeline section 5, anti-alkali liquor refluence fluid reservoir 12 I-shaped section is presented herein below
6, in anti-alkali liquor refluence fluid reservoir 12, it is placed with an anti-alkali liquor refluence floating blocking 13；
Anti-alkali liquor refluence floating blocking 13 includes blocking 14, ball float 15 and counterweight foot 16；Being arranged above with of ball float 15 is blocked up
Chock plug 14, ball float 15 multiple counterweight foot 16 is provided below, the weight of multiple counterweight feet 16 is more than the weight of blocking 14；Anti-
Alkali liquor flow backwards float blocking 13 can emersion liquid level in a liquid；The top end diameter of blocking 14 is less than the caliber of Large Diameter Pipeline section 5, stifled
The bottom diameter of chock plug 14 is more than the caliber of Large Diameter Pipeline section 5.
Acid gas in the present invention, sour gas, strong acid escaping gas are all the identical concept, only chat convenient and use not because stating
Same word.
This utility model mainly solve a highly acid collection and confinement of gases get up be neutralized with highly basic liquid react into saline solution and
Water, makes acid gas not enter air, free from environmental pollution.
The device of this utility model connects strong acid liquid, for preventing acid gas with highly basic liquid acid gas conduit 3
Air pressure change in conduit 3, causes highly basic liquid to blow back among strong acid liquid and produces huge strong breaking reaction, and this practicality is new
Type first, is managed greatly less than the pipe diameter of Large Diameter Pipeline section 5 with the pipe diameter of acid flow control valve 8, second pipe with small pipe diameter section 4
The pipe diameter of footpath section 5 is less than or equal to I-shaped section 6 pipe diameter；3rd with anti-alkali liquor refluence fluid reservoir 12；4th uses
Anti-alkali liquor refluence fluid reservoir 12 is placed alkali liquor refluence floating blocking 13；5th does not puts with the downwardly open funnel of I-shaped section 11
Enter the upper part height among alkali liquor and be the technical pattern such as 3-10 centimetre and method can well prevent highly basic liquid from blowing back into
Among strong acid liquid, so that being neutralized the technology of reaction highly acid gas with highly basic liquid, have can practicality.
First with acid flow control valve 8: can prevent highly basic liquid from flowing backwards with manual control with acid flow control valve 8
Enter among strong acid liquid.
Second is less than the pipe diameter of Large Diameter Pipeline section 5, the pipe diameter of Large Diameter Pipeline section 5 with the pipe diameter of pipe with small pipe diameter section 4
Less than or equal to I-shaped section 6 pipe diameter: the acid gas pressure that purpose is to make in pipe with small pipe diameter section 4 is more than Large Diameter Pipeline section
Acid gas pressure in 5, makes sour gas be flowed to Large Diameter Pipeline section 5 by pipe with small pipe diameter section 4, keeps normal acid gas to process state,
Also can prevent highly basic liquid from blowing back among strong acid liquid.
3rd with anti-alkali liquor refluence fluid reservoir 12: clear up the aqueous alkali of bottle 1 to wide-mouth for storing to flow backwards from acid absorption cell 2
Body, when having highly basic liquid in anti-alkali liquor refluence fluid reservoir 12, rises to alkali liquor liquid by downwardly open for I-shaped section funnel 11
More than face, alkali liquor flows back to acid absorption cell 2 automatically.
4th with placing alkali liquor refluence floating blocking 13 in anti-alkali liquor refluence fluid reservoir 12: this is one and is automatically prevented from highly basic
Liquid blows back into the technology among strong acid liquid, if it is too fast to blow back into the speed among strong acid liquid at highly basic liquid, or nothing
People at the scene time, after aqueous alkali flows backwards in anti-alkali liquor refluence fluid reservoir 12, alkali liquor flows backwards and floats blocking 13 at highly basic liquid
Will float to liquid level, owing to the weight of multiple counterweight feet 16 is more than the weight of blocking 14, blocking 14 is just flow backwards floating at alkali liquor
Above dynamic blocking 13, thus blocking 14 just blocks the pipe of Large Diameter Pipeline section 5, makes the highly basic liquid of refluence can not enter big pipe
The pipe of footpath section 5, has blocked highly basic liquid and has flowed back to the road warp among strong acid liquid, can be automatically prevented from highly basic liquid and blow back into by force
Among acid solution body.
The 5th upper part height do not put among alkali liquor with the downwardly open funnel of I-shaped section 11 is 3-10 centimetre:
Making the broad space having 3-10 centimetre high in acid absorption cell 2 between liquid level and the pipe of I-shaped section 6 of strong acid liquid, acid is inhaled
When in receipts cup 2, the volume of highly basic liquid increases few, highly basic liquid can not enter among the pipe of I-shaped section 6, also can prevent
Only highly basic liquid blows back among strong acid liquid.It addition, I-shaped section downwardly open funnel 11 structure also add sour gas
Body and the contact surface of highly basic liquid, the initial contact surface preventing bronsted lowry acids and bases bronsted lowry is little, is producing huge strong chemical reaction in local, prevents local
The volume of liquid quickly increases and causes highly basic liquid to blow back among strong acid liquid.
Advantage of the present utility model: designed by multiple technologies, can carry out preventing highly basic liquid from blowing back into automatically and manually
Among strong acid liquid, the acid Volatile Gas physical ability clearing up in bottle is made to flow into the alkaline solution in acid absorption cell by acid gas conduit
Among, carry out harmless treatment.When making mensuration heavy metal sample, during clearing up animals and plants processed sample, harmful gas i.e. acid
Property volatilization gas does not enter air, free from environmental pollution.In a word, have and of the present utility model prevent highly basic liquid from blowing back into strong acid liquid
Among technology, could be with collecting and the mode of harmless treatment acidity volatilization gas carry out clearing up sample；The most still can only
Entering air with acid volatilization gas, air-polluting mode carries out clearing up sample.
