Abstract
The invention relates to a spraying device, and specifically relates to a spraying device of a wet flue gas desulfuration (WFGD) absorbing tower. The device comprises a spraying pipe and a spraying disc, which is arranged below the spraying pipe, the upper part of the spraying disc is a liquid collecting disc, the lower part of the spraying disc is provided with a plurality of liquid splitting holes, the pipe diameter of the upper part of the spraying pipe is two thirds of that of the lower part of the spraying pipe, the cross section of the spraying disc is in a trapezoid structure, the hole diameter gradually increases from the inside to the outside, and the axes of the liquid splitting holes are in the same direction as the axial direction of the spraying pipe. The spraying device of a wet flue gas desulfuration (WFGD) absorbing tower has the advantages of even spraying and good spraying effect.
Description
Technical field
The present invention relates to a kind of spray equipment, be specifically related to a kind of spray equipment of wet flue gas desulfurization absorption tower.
Background technology
In the flue gas of the industrial production such as boiler and cement kiln discharge, contain a large amount of SO
2the absorption process of wet process of FGD denitration at present, the general flue gas that adopts enters from spraying layer below in absorption tower, the absorption slurries counter current contacting spraying in certain work area with spray equipment, for removing the sulfur dioxide of boiler smoke, after the washing of lime stone slurry, sulfur dioxide in flue gas is removed.The wet flue gas desulfurization absorption tower that the industries such as flue gas desulfurization are at present used, in absorption tower, spray equipment can not spray slurries equably, and spraying effect is not good.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of spray equipment that has uniform spraying, wet flue gas desulfurization absorption tower that spraying effect is good is provided.
In order to solve the problems of the technologies described above, the invention provides a kind of spray equipment of wet flue gas desulfurization absorption tower, comprise shower and the shower tray that is connected to described shower below, shower tray top is catch tray, bottom is provided with some separatory hole, and the top caliber of shower is 2/3rds of bottom caliber, and shower tray cross section is trapezium structure, it is large that the aperture in separatory hole becomes from inside to outside gradually, and separatory axially bored line is consistent with the axis direction of described shower.
Adopt the spray equipment tool of the wet flue gas desulfurization absorption tower of technique scheme to have the following advantages: 1, the top caliber of described shower is 2/3rds of bottom caliber, sprayed slurry is by the large caliber of the little bottom of top caliber caliber, make wider in the diffusion of shower of slurries, be conducive to the uniformity of spray; 2, shower tray cross section is trapezium structure, and along with the increase gradually in cross section, flow velocity reduces relatively, is conducive to liquid through the uniformity of separatory hole ejection; The separatory hole of the spray equipment 3, arranging in absorption tower, aperture expands from inside to outside gradually, and because intermediate grout flow velocity is relatively very fast, median pore radius is relatively little, has effectively controlled the uniformity of slurries ejections; 4, separatory axially bored line is consistent with the axis direction of described shower, makes slurries be smoothly through separatory hole, and sprayed slurry, makes spraying effect good equably.
As preferred version, in order further to guarantee the uniformity of slurries ejection, described separatory axially bored line tilts to described shower axis direction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the spray equipment of wet flue gas desulfurization absorption tower of the present invention;
Fig. 2 is the upward view of the spray equipment of wet flue gas desulfurization absorption tower of the present invention;
Fig. 3 is the sketch of wet flue gas desulfurization absorption tower of the present invention;
In figure: 1-shower, 2-shower tray, 20-separatory hole, 21-catch tray.
the specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, Figure 2 and Figure 3, the invention provides the spray equipment of wet flue gas desulfurization absorption tower, comprise shower 1 and the shower tray 2 that is connected to shower 1 below, shower tray 2 tops are catch tray 21, bottom is provided with some separatory hole 20, and the top caliber of shower 1 is 2/3rds of bottom caliber, and shower tray 2 cross sections are trapezium structure, it is large that the aperture in separatory hole 20 becomes from inside to outside gradually, and separatory axially bored line is consistent with the axis direction of shower 1.Separatory hole 20 axis tilt to shower 1 axis direction, guaranteed the uniformity of slurries ejections, because the caliber of shower 1 is up-small and down-big, top caliber is 2/3rds of bottom caliber, be conducive to the wider of sprayed slurry diffusion, spray equipment can be evenly sprayed in certain work area absorb slurries, spraying effect is good.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the premise without departing from the principles of the invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
Claims (2)
1. the spray equipment of a wet flue gas desulfurization absorption tower, comprise shower and the shower tray that is connected to described shower below, described shower tray top is catch tray, bottom is provided with some separatory hole, it is characterized in that: the top caliber of described shower is 2/3rds of bottom caliber, shower tray cross section is trapezium structure, and it is large that the aperture in separatory hole becomes from inside to outside gradually, and separatory axially bored line is consistent with the axis direction of described shower.
2. according to the spray equipment of the wet flue gas desulfurization absorption tower described in claim 1, it is characterized in that: described separatory axially bored line tilts to described shower axis direction.
