Abstract
A flue gas desulfurization tower with uniform tube type flue gas distribution machines relates to the field of environmental protection and the technical field of flue gas desulfurization engineering. A flue gas inlet (1) is formed in the middle of the outer side of a tower body (2), spraying layers (4) are arranged in the tower body (2) and are arranged at the upper part of the flue gas inlet (1), demisters (5) are arranged at the upper part of the spraying layers (4), a flue gas outlet (6) is formed in the top of the tower body (2), and the uniform tube type flue gas distribution machines (3) are arranged at the lower parts of the spraying layers (4), and are arranged at the upper part of the flue gas inlet (1). According to the flue gas desulfurization tower, a method in which the uniform tube type flue gas distribution machines are arranged above the flue gas inlet in the tower is adopted, so that the ascending velocities of flue gas are similar at different positions of the cross section of the tower, and the desulfurization efficiency is improved.
Description
Technical field:
The utility model relates to field of environment protection flue-gas desulfurizing engineering technical field, is specifically related to a kind of fume desulfurizing tower with tubular type flue gas even distribution device.
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.Its flue gas flow of flue-gas desulfurizing engineering of reality mostly at hundreds thousand of cubic meter per hour to more than hundred ten thousand steres, the diameter of desulfurizing tower all at several meters to more than tens meters, after flue gas enters the desulfurizing tower of prior art, because the flow velocity of its rising of jet effect is extremely uneven, near upflow velocity minimum close gas approach, and near near the upflow velocity maximum import opposite tower wall, this brings very adverse influence to desulfuration efficiency.
The utility model content:
The purpose of this utility model provides a kind of fume desulfurizing tower with tubular type flue gas even distribution device, it is by arranging the way of tubular type flue gas even distribution device above the gas approach in tower, make the upflow velocity of flue gas approaching substantially, increase desulfuration efficiency at the diverse location of tower section.
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, tubular type flue gas even distribution device 3, spraying layer 4, demister 5 and exhanst gas outlet 6; Gas approach 1 is arranged on the outer middle side part of tower body 2, spraying layer 4 is arranged on the inside of tower body 2, and spraying layer 4 is arranged on the top of gas approach 1, demister 5 is arranged on the top of spraying layer 4, exhanst gas outlet 6 is arranged on the top of tower body 2, the bottom of described spraying layer 4 is provided with tubular type flue gas even distribution device 3, and tubular type flue gas even distribution device 3 is arranged on the top of gas approach 1.
The utlity model has following beneficial effect: it makes the upflow velocity of flue gas approaching substantially at the diverse location of tower section by arrange the way of tubular type flue gas even distribution device above the gas approach in tower, increases desulfuration efficiency.
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, tubular type flue gas even distribution device 3, spraying layer 4, demister 5 and exhanst gas outlet 6; Gas approach 1 is arranged on the outer middle side part of tower body 2, spraying layer 4 is arranged on the inside of tower body 2, and spraying layer 4 is arranged on the top of gas approach 1, demister 5 is arranged on the top of spraying layer 4, exhanst gas outlet 6 is arranged on the top of tower body 2, the bottom of described spraying layer 4 is provided with tubular type flue gas even distribution device 3, and tubular type flue gas even distribution device 3 is arranged on the top of gas approach 1.
Described tower body 2 can be circular, square, rectangle or other shape.
Pipe material in the described tubular type flue gas even distribution device 3 can be a metal, and for example stainless steel also can be nonmetal, and for example fiberglass can also be metal and nonmetallic combination, for example carbon steel pipe outsourcing fiberglass.
This specific embodiment realizes that the technical measures and the principle of flue gas even distribution in the tower are: arrange some pipes on the horizontal cross-section of tower, it is tubular type flue gas even distribution device 3, each pipe is parallel to each other, and the center line of pipe is with the center line spatial vertical of gas approach, at the flue gas upflow velocity in distance gas approach 1 farthest maximum, and in the most minimum rule of distance gas approach 1, the gap that forms between each adjacent pipe changes by certain functional relation, apart from gap, gas approach 1 farthest minimum, thereby the resistance maximum that flue gas is caused, apart from gas approach 1 gap maximum the most nearby, to the resistance minimum that flue gas causes, it is approximately everywhere identical with this flue gas flow rate to be adjusted to.
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, the tubular type flue gas even distribution device 3 that is installed in the gas approach top from level passes, the uneven phenomenon of flow velocity obtains changing, and becomes the approaching substantially parallel flue gas stream that makes progress of flow velocity on tower section everywhere.It is up that flue gas continues, and removed sulfur dioxide by the absorption liquid that spray from top spraying layer 4, again through being installed on after tower body 2 removes mist near the demister 5 at top, by the exhanst gas outlet 6 discharge desulfurizing towers of cat head.
This specific embodiment makes the upflow velocity of flue gas approaching substantially at the diverse location of tower section by arrange the way of tubular type flue gas even distribution device above the gas approach in tower, increases desulfuration efficiency.
