Specific embodiment

As Figure 1-Figure 4, the neutralizing tower of the present embodiment includes a tower body 1, and tower body 1, which is equipped with, enters tower for sour gas Intracorporal sour gas entrance 2 and gas vent 3 for the gas discharge after neutralizing, are equipped with by drawing outside tower body inside tower body 1 Enter the spray pipeline 4 inside tower body, sour gas input pipe 5 is connected at sour gas entrance 2, sour gas entrance 2 exports Positioned at the middle and lower part of 1 side wall of tower body, sour gas input pipe 5 is obliquely installed at sour gas entrance 2, sour gas input The arrival end height of pipe 5 be greater than outlet end: spray pipeline 4 include conveying alkaline solution pipeline 41, be installed on pipeline 41 and Spray pump 42 outside tower body and the nozzle on pipeline 43, the nozzle 43 is located on the central axis of tower body 1 and height Degree is higher than sour gas entrance 2.

When work, the sour gas input pipe 5 for the inclined that dips down, which is sour gas, can allow sour gas entering in tower Speed in tower immediately upper will not escape and can up escape again when encountering tower body barrel along entrance downlink, extend acidity The operating path of gas, and the speed escaped on acid gas is reduced, so that sour gas is rested on the time lengthening reacted in tower；Separately Outside, spray head is located at tower center position directly above higher than inclined pickling entrance, sprays the acid gas escaped upwards in the process and spray The alkaline water mist that leaching head sprays down collides, secondary to reduce the speed escaped in pickling；Soda acid occurs when collision simultaneously Neutralization reaction, reacts the water generated and neutral compound is fallen into tower along spray water mist, increases the covering of spray water mist Closeness strengthens neutralization.

In order to effectively collect after spray water caused by the water mist liquid that falls and neutralization, compound and miscellaneous Matter, in the present embodiment, middle and lower part is equipped with angularly disposed diaphragm 6, angularly disposed diaphragm 6 lower one in tower body 1 Refluxing opening 7 is equipped between end and tower body inner wall；Settling zone 8 and reflux homogeneity range 9 are equipped with below diaphragm 6；Settling zone 8 and return It is isolated between stream homogeneity range 9 by the first lower clapboard 10.

It is arranged after diaphragm 6, the mixed liquor for being mingled with impurity of whereabouts is by the guiding of diaphragm 6 by refluxing opening 7 are flowed into settling zone 8, and by the precipitating of settling zone 8, contamination precipitation to settling zone bottom, mixed liquor is through the first lower clapboard 10 It overflows in reflux homogeneity range 9.

In order to which the mixed liquor for reaching upper step in reflux homogeneity range 9 is more uniform, and do not acted on by agitating device It realizes uniformly, in order in the present embodiment, the reflux homogeneity range 9 is divided into the first recirculating zone 91 and the by the second lower clapboard 11 Two recirculating zones 92.By the separation of the second lower clapboard 11, makes the overflow water route for forming detour in the second recirculating zone 9, reach into one Walk the effect of uniform mixed liquor.

The degree of mixing of mixed liquor in order to further increase, in the present embodiment, the settling zone 8 is equipped with settling zone demarcation plate 12,12 top edge of settling zone demarcation plate is fixed on 6 lower surface of diaphragm, the lower edge of settling zone demarcation plate 12 and heavy The gap 13 that water supply stream passes through is equipped between the settling zone bottom surface in shallow lake area 8.

The degree of mixing of mixed liquor in order to further increase, in the present embodiment, first recirculating zone 91 is equipped with first time Stream separates plate 14, and 14 top edge of the first recirculating zone partition, which is fixed on, flows backwards 6 lower surface of partition, the first recirculating zone partition 14 it is following The gap that water supply stream passes through is equipped between edge and the first recirculating zone bottom surface.

More than mixed liquor processing after, include in mixed liquor it is remaining spray neutralize after alkaline solution with And water caused by neutralization.This remaining mixed liquor can be used as the raw material of circulated sprinkling, reduce alkaline solution with this With the dosage of water.

In order to realize above-mentioned circulated sprinkling effect, in the present embodiment, second recirculating zone 92 connects oriented second The dosing injection pipe 15 of alkaline medicinal liquid is injected in recirculating zone 92, tap water dilution alkaline medicinal liquid shape is injected into the second recirculating zone 92 At the tap water injection pipe 16 of alkaline solution；The spray pipeline 4 is connected to the second recirculating zone 92 and is extracted by the second recirculating zone Alkaline solution is for spraying.

In the use of alkaline medicinal liquid, if lasting sprayed using being sprayed for same pH value, often will cause with The unmatched problem of the pH value of the sour gas of required processing, alkalinity is too low to be easy to cause neutralization insufficient, and alkalinity is excessively high to be easy It causes the pH value of remaining mixed liquor persistently to increase, in order to solve this problem, in the present embodiment, is equipped in the tower body 1 PH value detection device 17, the dosing injection pipe 15, which is equipped with, adjusts alkaline medicine according to the testing result of pH value detection device 17 The dosing pump 18 of water injection rate.

PH value detection device is equipped with the peak and minimum of working condition, and in minimum, pH value detection device can be given Dosing pump electric signal is given, it is allowed to pump in akaline liquid pump to tower to improve the pH value in tower, when PH reaches the peak of setting, PH value detection device tells that it stops pump liquid to dosing pump signal, while neutralizing tower is in and when pickling gas, liquid in tower PH value can gradually be fallen after rise to the minimum of setting, and dosing pump is opened when reaching minimum, and continue to pump akaline liquid, pH value in tower It is highest and lowest always during this circulation to setting within the scope of.It is dynamic by pH value detection device in this way Detection is in the ejecting liquid in tower within the scope of setting always to give dosing pump open and close pump liquid system.

The water generated is done in order to effectively recycle neutralization, and in the present embodiment, 1 top of tower body is equipped with a taper The bending angle steel 19 that sheath multilayer shifts to install.

Bending angle steel 19 is overlooked in order to avoid remaining sour gas forms acid solution in conjunction with the water on bending angle steel 19, this In embodiment, secondary spraying pipe 20 is additionally provided with above the bending angle steel of Multi-layer staggered setting in tower body 1.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported Used in other related technical areas, it is also included in the patent protection scope of the utility model.
