Abstract
The utility model discloses a hydrochloric acid waste gas absorption tower, which comprises a tower body, an alkaline solution tank, a defoaming device and an alkaline solution circulating power device, wherein the tower body is used for reaction and absorption, the alkaline solution tank is installed below the tower body, the deforming device is installed in the alkaline solution tank and the alkaline solution circulating power device is connected between the tower body and the alkaline solution tank. Alkaline solution in the alkaline solution tank is pumped into the tower body and reacts with a small quantity of hydrochloric acid waste gas. The alkaline solution after reaction is defoamed by the deforming device and enters the alkaline solution tank again for cycle use to absorb a small quantity of hydrochloric acid waste gas. The defoaming treatment enables the foam in the alkaline solution tank to be reduced to prevent a large quantity of foam from entering a circulating pump and affecting the normal operation of the circulating pump. The utility model has the advantages that the air resistance is small, the absorption efficiency is high, the structure is simple, the installation is easy and the operation and the maintenance are convenient.
Description
Technical field
The utility model relates to the absorption tower technical field, relates in particular to a kind of absorption tower of practical hydrochloric acid waste gas.
Background technology
During the chemical industry forming gas, often be accompanied by the excessive of the generation of a small amount of manufacture gas or certain unstripped gas,, will have a strong impact on the quality of object gas if this class gas is not removed; Reclaiming foreign gas in addition effectively also is very important for reducing environmental pollution, controlling production cost.
The absorption tower is in order to gas is absorbed the tower of operation.Utilize admixture of gas solubility different or utilize chemical reaction in liquid-absorbant, make Yi Rong's or reactive component be dissolved in the absorbent, and be called absorption with other component separating process.During operation, from the liquid-absorbant of cat head spray with contact closely on each layer filler or the tower tray tower by the admixture of gas of rising at the bottom of the tower so that absorb.Known hydrochloric acid exhaust gas absorption device, vapour lock are big and absorptivity is low, major polluting atmosphere environment.
The utility model content
Technical problem to be solved in the utility model provides a kind of absorptivity height, vapour lock is little, and operation maintenance is the hydrochloric acid waste gas absorption tower easily.
For solving the problems of the technologies described above, the technical solution of the utility model is: the hydrochloric acid waste gas absorption tower comprises: tower body, and described tower body inside has reaction compartment; Spray equipment, described spray equipment are installed on the inside of described tower body and are positioned at the top of reaction compartment, are used for spraying in reaction compartment alkali lye; Reaction carriers, described reaction carriers are arranged in the described reaction compartment; The alkali lye pond, described alkali lye pond is arranged at the below of described tower body; Described absorption tower also comprises the alkali lye cycle power device, and described alkali lye cycle power device is used to make alkali lye to circulate between alkali lye pond and spray equipment; Defoaming device, described defoaming device are installed in the described alkali lye pond.
As a kind of optimized technical scheme, described defoaming device comprises the froth breaking pipe, and the upper end of described froth breaking pipe extends at the bottom of the tower of tower body, and described froth breaking pipe lower end extends at the bottom of the pond in alkali lye pond.
As a kind of optimized technical scheme, described alkali lye cycle power device comprises circulating pump.
As a kind of optimized technical scheme, described spray equipment comprises the shower nozzle that is installed on the shower.
As a kind of optimized technical scheme, described reaction carriers is a filler.
After having adopted technique scheme, the beneficial effects of the utility model are: because this hydrochloric acid waste gas absorption tower comprises: the tower body that is used to react absorption, be installed in the alkali lye pond of described tower body below, be installed in the defoaming device in the alkali lye pond, be connected in the alkali lye cycle power device between described tower body and the alkali lye pond; So, the alkali lye in the alkali lye pond be pumped to tower body and with a spot of hydrochloric acid waste gas reaction, defoaming treatment enters the alkali lye pond once more through defoaming device for reacted alkali lye, alkali lye recycles, and is used to absorb small amount of hydrochloric acid waste gas.Defoaming treatment makes the alkali lye pond reduce bubble, prevents that a large amount of bubbles from entering circulating pump, influences the circulating pump operate as normal.The utility model has realized that vapour lock is little, absorptivity is high, and simple in structure, be easy to install, operation maintenance is convenient.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
In the accompanying drawing: 1. gas outlet; 2. tower body; 3. air inlet; 4. alkali lye import; 5. froth breaking pipe; 6. circulating pump; 7. alkali lye pond; 8. shower nozzle; 9. filler; 10. aperture.
The specific embodiment
The hydrochloric acid waste gas absorption tower as shown in drawings, comprising:
Be provided with alkali lye pond 7 below described tower body 2, described alkali lye pond 7 and described tower body 2 are connected by flange, and described alkali lye pond 7 sidewall upper are provided with alkali lye import 4;
In the described alkali lye pond 7 froth breaking pipe 5 is installed, the upper end of described froth breaking pipe 5 extends at the bottom of the tower of tower body 2, and described froth breaking pipe 5 lower ends extend at the bottom of the pond in alkali lye pond 7, has the aperture 10 of some in froth breaking pipe bottom, flow out for the alkali lye behind the froth breaking, and prevent that foam from flowing out;
Circulating pump 6, the input of described circulating pump 6 are connecting 7 bottoms, alkali lye pond, and the output of described circulating pump 6 is connecting shower nozzle 8.
The operation principle of froth breaking pipe: contain the part bubble from the fallen alkali lye of filler, because bubble density is littler than alkali lye, so float over froth breaking pipe top, the absorption liquid density that does not contain bubble is big, and constantly the aperture from froth breaking pipe bottom flows out.The bubble of come-up is along with time lengthening is constantly broken.The main effect of froth breaking pipe is to prolong the time of staying of foam in the froth breaking pipe, impels it to break, and reaches the froth breaking purpose.Avoid too much foam to enter the pump housing, influence circulating pump work.
Operation principle of the present utility model: at first add alkali lye to alkali lye pond 7 from alkali lye import 4, the ON cycle pump 6 then, and circulating pump 6 is extracted into tower body 2 top shower nozzles 8 with the alkali lye in the alkali lye pond 7, the filler 9 of 2 li dresses of alkali lye spray tower body.Small amount of hydrochloric acid waste gas is entered from air inlet 3, small amount of hydrochloric acid waste gas in tower body 2 with alkaline reaction, small amount of hydrochloric acid waste gas is absorbed, tail gas is discharged by gas outlet 1.Alkali lye after tower body 2 internal reactions falls into froth breaking pipe 5, froth breaking in froth breaking pipe 5, and the opening from froth breaking pipe 5 lower ends enters alkali lye circulatory pool 7 then.Alkali lye in the alkali lye circulatory pool 7 is recycled pump 6 once more and is extracted into the tower body top, circulates to absorb hydrochloric acid waste gas.
The utility model adopts the froth breaking pipe to eliminate the bubble that produces in the reaction, prevents that bubble from entering circulating pump, influences the operate as normal of circulating pump.And the utility model reasonable in design, be easy to install, operation maintenance is convenient.
