Abstract
The utility model relates to an absorption tower which comprises a tower body, tower internals and fillers, wherein the top end of the tower body is provided with an air outlet; the lower end part of the tower body is provided with an air inlet; the tower body is formed by combining an inner layer and an outer layer; the tower internals comprise a spraying pipe, more than two filler support plates, a liquid distribution device, liquid collecting discs and a demister; the spraying pipe is arranged on the upper end part of the tower body; the liquid distribution device is arranged below the spraying pipe; the filler support plates are distributed in the tower body; the fillers are arranged on the filter support plates; the liquid collecting discs are arranged between each two adjacent filler support plates; the demister is arranged above the spraying pipe; and a liquid outlet is arranged on one side of the bottom part of the tower body. The absorption tower provided by the utility model is simple in structure; the tower body has the advantages of favorable intensity, high-temperature resistance, acid and alkali resistance and the like by virtue of a dual-layer structure; and liquids are collected by the liquid collecting discs and then are distributed again, so that gas and liquid phases can be distributed uniformly, and the separation efficiency is improved.
Description
Technical field
The utility model relates to a kind of environmental protection equipment, specifically relates to a kind of absorption tower.
Background technology
The absorption tower is the equipment of realizing absorption operation, is divided three classes by the Gas-Liquid Contacting form.To be gas be dispersed in plate column, bubble absorbing tower, stirring bubble absorbing tower in the liquid phase with bubble shape to the first kind; To be liquid be dispersed in injector, Venturi tube, spray tower in the gas phase with droplet-like to Equations of The Second Kind; The 3rd class is packed absorber and the film-falling absorption tower that liquid contacts with gas phase with membranaceous motion.The type of flow of gas-liquid two-phase can adverse current also can and flow in the tower.Usually adopt counter-current operation, absorbent adds mobile from top to bottom with cat head, contact with the gas that flows from bottom to top, and the liquid that has absorbed absorbent is discharged at the bottom of tower, and purified gas is discharged from cat head.
The tower body on existing absorption tower is generally single layer structure, has the problems such as resistance to elevated temperatures and acid-fast alkali-proof poor-performing, after long-time the use, along with the soda acid in the air-flow or other corrosive gas to the effect on absorption tower, also will be affected its service life; In addition, when liquid flows downward along packing layer, there is the trend of concentrating to the tower wall gradually on existing absorption tower in use, so that near the flow quantity the tower wall increases gradually, this phenomenon is called wall stream.Wall stream effect causes gas-liquid two-phase skewness in packing layer, thereby mass-transfer efficiency is descended.
The utility model content
In order to overcome Shortcomings in the present technology, the utility model provides a kind of long service life, absorption tower that separative efficiency is high.
A kind of absorption tower, comprise tower body, tower internals and filler, the tower body top is provided with air outlet, the tower body bottom is provided with air inlet, described tower internals comprises shower, packing support plate and demister, described tower body is by inside and outside two-layer combining, described tower internals also comprises liquid distribution device and liquid collection dish, described shower is arranged on the tower body upper end, and liquid distribution device is arranged on the shower below, and described packing support plate is distributed in tower body inside, described filler is arranged on the packing support plate, described packing support plate is more than two, and the liquid collection dish is arranged between two blocks of adjacent packing support plates, and described demister is positioned at the shower top; Described tower body bottom one side is provided with liquid outlet.
Preferably, described shower is provided with several equally distributed mouth sprays.
Preferably, the quantity of described packing support plate is two, and wherein one is arranged on the air inlet top, and another piece is arranged on the middle part of tower body.
Preferably, described liquid collection dish is arranged on the below of middle part packing support plate.
Preferably, described tower body both sides are provided with several hand holes, and described tower body bottom one side is provided with manhole.It is inner to be convenient to installation, dismounting, cleaning and repair apparatus.
The utility model is simple in structure, adopts double-decker, makes tower body have the advantages such as better intensity, resistance to elevated temperatures, acid-fast alkali-proof performance; The liquid collection dish is set, carries out liquid after liquid collection is got up and distribute again, can effective uniform liquid phase, improve separative efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of absorption tower, comprise tower body 1, tower internals and filler 2, tower body 1 top is provided with air outlet 3, tower body 1 bottom is provided with air inlet 4, described tower internals comprises shower 5, packing support plate, liquid distribution device 7, liquid collection dish 8 and demister 9, and described tower body 1 is by inside and outside two-layer combining; Described shower is provided with several equally distributed mouth sprays, and described shower 5 is arranged on tower body 1 upper end, and liquid distribution device 7 is arranged on shower 5 belows, and described demister 9 is positioned at shower 5 tops.
Described packing support plate is distributed in tower body inside, and described filler 2 is arranged on the packing support plate, and the quantity of described packing support plate is two, and wherein a packing support plate 6 is arranged on air inlet 4 tops, and another piece packing support plate 10 is arranged on the middle part of tower body 1; Described liquid collection dish 8 is arranged on the below of middle part packing support plate 10; Described tower body 1 bottom one side is provided with liquid outlet 11.
Described tower body both sides respectively are provided with 2 hand holes 12, and described tower body bottom one side is provided with manhole 13.
During use, waste gas enters the absorption tower through air inlet, adopt counter-current operation, absorbent adds mobile from top to bottom with cat head, contact with the gas that flows from bottom to top, is positioned at the liquid collection dish at middle part, carrying out liquid after liquid collection got up distributes again, avoided the generation of wall stream effect, the liquid that has absorbed absorbent liquid outlet at the bottom of the tower is discharged, and purified gas discharges from the cat head air outlet.
