Abstract
The utility model discloses a flue gas desulfurization tower with a liquid-gas re-distributor and relates to a smoke gas desulfurization project of the environmental protection field. A flue gas inlet (1) is formed at the middle part of a tower body (2); a spraying layer (4) is arranged in the tower body (2); the spraying layer (4) is arranged at the upper part of the flue gas inlet (1); a demister (5) is arranged at the upper part of the spraying layer (4); a flue gas outlet (6) is formed at the top of the tower body (2); and the liquid-gas re-distributor (3) is arranged at the lower part of the spraying layer (4). A tapered ring, i.e., the liquid-gas re-distributor, which is adhered to the inner wall, is arranged at the proper position of the tower body and used for guiding liquid flowing down along the tower wall into the space inside the tower, so that the desulfurization effect of the liquid is sufficiently brought into play.
Description
Technical field:
The utility model relates to a kind of flue-gas desulfurizing engineering of field of environment protection, is specifically related to a kind of fume desulfurizing tower with liquid gas redistributor.
Background technology:
Remove the sulfur dioxide in the industrial smoke and make the process of gas cleaning be called flue gas desulfurization.Present flue gas desulfur device more than 90% adopts wet desulfurizing process, be upwards to flow after flue gas enters the absorption tower, absorption liquid is sprayed onto space in the tower by several nozzles that are fixed on top, absorption tower spraying layer equably with the form of tiny liquid pearl, and land downwards because of the gravity effect, contact with the flue gas that upwards flows and absorption reaction takes place, most of sulfur dioxide in the flue gas is absorbed by liquid absorption and is removed, the flue gas that continues to rise is discharged the absorption tower through after removing most of liquid entrainment of carrying secretly near the demister at top, absorption tower from the exhanst gas outlet of cat head.The absorption tower desulfurizing tower that is called in the field of business that is used for flue gas desulfurization.Because the layout of spraying layer nozzle can be sprayed onto the tower wall by some doctor solution inevitably, flow down and do not rise absorption along the tower wall, equally, the rising of flue gas in tower flowed and also can be produced attached wall phenomenon, influence assimilation effect, these all are that prior art needs improved problem.
The utility model content:
The purpose of this utility model provides a kind of fume desulfurizing tower with liquid gas redistributor, it is provided with the taper ring that is attached at inwall in the tower body appropriate location, be called liquid gas redistributor, the desulfidation of this part liquid is given full play in space in the tower that will lead again along the liquid that the tower wall flows down.Liquid gas redistributor can play perturbation action to the flue gas of attached jet simultaneously, thereby strengthens assimilation effect.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises gas approach 1, tower body 2, liquid gas redistributor 3, spraying layer 4, demister 5 and exhanst gas outlet 6; Gas approach 1 is arranged on the middle part of tower body 2, spraying layer 4 is arranged in the tower body 2, and spraying layer 4 is arranged on the top of gas approach 1, and demister 5 is arranged on the top of spraying layer 4, exhanst gas outlet 6 is arranged on the top of tower body 2, and the bottom of described spraying layer 4 is respectively arranged with liquid gas redistributor 3.
The utlity model has following beneficial effect: it is provided with the taper ring be attached at inwall in the tower body appropriate location, be called liquid gas redistributor, and the desulfidation of this part liquid is given full play in space in the tower that will lead again along the liquid that the tower wall flows down.Liquid gas redistributor can play perturbation action to the flue gas of attached jet simultaneously, thereby strengthens assimilation effect.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it comprises gas approach 1, tower body 2, liquid gas redistributor 3, spraying layer 4, demister 5 and exhanst gas outlet 6; Gas approach 1 is arranged on the middle part of tower body 2, spraying layer 4 is arranged in the tower body 2, and spraying layer 4 is arranged on the top of gas approach 1, and demister 5 is arranged on the top of spraying layer 4, exhanst gas outlet 6 is arranged on the top of tower body 2, and the bottom of described spraying layer 4 is respectively arranged with liquid gas redistributor 3.
Described tower body 2 can be circular, square, rectangle or other shape.
The material of described liquid gas redistributor 3 generally should be identical with tower body 2, can be stainless steel, fiberglass, carbon steel lining rubber, carbon steel lining glass flake or carbon steel coated with glass fibre reinforced plastics.
Described spraying layer 4 can be one deck, two-layer or multilayer.
The workflow of this specific embodiment is: flue gas enters desulfurizing tower tower body 2 and upwards mobile from the gas approach 1 that is positioned at tower body 2 middle parts, removed sulfur dioxide by the absorption liquid that sprays from top spraying layer 4, through being installed on after tower body 2 removes mist near the demister 5 at top, discharge desulfurizing towers again by the exhanst gas outlet 6 of cat head.Liquid gas redistributor 3 is installed in spraying layer 4 below certain altitudes, is a taper ring as shown in the figure, and horizontal positioned is upside down little, head-up is attached on the inwall of tower body 2 greatly.When absorption liquid is directed onto or is splashed to the tower wall and flows down along the tower wall, running into liquid gas redistributor 3 will be continued downward sprinkle by the taper ring space of leading in the tower, recovers absorption.Simultaneously, flue gas attaches flowing by 3 disturbances of liquid gas redistributor of tower wall, produces disorder and whirlpool, has strengthened the mass transfer effect with absorption liquid.
This specific embodiment is provided with the taper ring be attached at inwall in the tower body appropriate location, be called liquid gas redistributor, and the desulfidation of this part liquid is given full play in space in the tower that will lead again along the liquid that the tower wall flows down.Liquid gas redistributor can play perturbation action to the flue gas of attached jet simultaneously, thereby strengthens assimilation effect.
