Problems solved by technology

At present, in the process of using the absorption tower to purify the flue gas, since the main component of the slurry used for purifying the flue gas is calcium hydroxide solution, after absorbing the sulfur-containing gas in the flue gas, calcium sulfite is easily produced, and it is easy to generate calcium sulfite at the bottom of the absorption tower. forming deposits
[0004] In order to prevent slurry deposition in the existing conventional absorption tower, agitators or pulse suspension pumps are usually used to solve this problem, which not only increases additional equipment purchase costs, but also increases production energy consumption, which is not conducive to energy saving and reduction. implementation of platoons

Embodiment 1

[0038] like Figures 1 to 3 As shown, the present invention is a self-stirring absorption tower, including an absorption tower 11, the absorption tower 11 is the main body of the absorption flue gas reaction, and the outside of the absorption tower 11 is connected with a slurry circulation pump 12 and a smoke inlet pipe 13. The slurry circulating pump 12 is used for recycling the slurry, the slurry circulating pump 12 is provided with a slurry ejection pipe 14 and a slurry recovery pipe 15, the slurry ejection pipe 14 is located at the upper part of the absorption tower 11, the The slurry recovery pipe 15 is located at the bottom of the absorption tower 11, the side wall of the absorption tower 11 is provided with a plurality of first spoilers 21, and the first spoilers 21 are distributed in a ring shape, and the bottom of the absorption tower 11 is provided with multiple A second spoiler 22, the second spoiler 22 is annular distribution, the second spoiler 22 is perpendicular...

Embodiment 2

[0042] like Figures 4 to 6As shown, the present invention is a self-stirring absorption tower, the first spoiler 21 is hinged to the side wall of the absorption tower 11, and the first rotating shaft 31 is arranged on the top of the first spoiler 21, and the The upper part of the first rotating shaft 31 is provided with a swing disc 32, the swing disc 32 is hinged with the first rotating shaft 31, by rotating the swing disc 32, the angle of the first spoiler 21 can be changed, and the angle of the first spoiler 21 can be changed according to the kinetic energy of the slurry. The size is adjusted to fix the angle of the first spoiler 21, so that the slurry can obtain the largest turning range, and at the same time, because it is easy to form the accumulation of slurry sediment between the first spoiler 21 and the absorption tower 11, adjust the first spoiler The angle of 21 can use the slurry to wash away the sediment, which ensures the working efficiency of the first spoiler ...

Embodiment 3

[0047] like Figures 7 to 8 As shown, the present invention is a self-stirring absorption tower, the first spoiler 21 is located at the top of the lowest liquid level, the lower part of the first spoiler 21 is provided with a pressure sensor 51, and the absorption tower 11 A receiver 52 is arranged outside, and the receiver 52 is connected with a pressure sensor 51. When the slurry is below the minimum liquid level, the surface pressure of the pressure sensor 51 is zero, and the absorption tower 11 can be obtained by observing the data received by the receiver 52. The amount of internal slurry is convenient for the staff to add slurry in time.

[0048] In order to ensure the operating efficiency of the whole device, the surface of the first spoiler 21 and the second spoiler 22 is provided with a protruding block 6, and the protruding block 6 can prevent sediment from being deposited on the first spoiler 21 and the second spoiler 22. The surface of the second spoiler 22 gather...

Abstract

The invention discloses a self-stirring absorption tower and relates to the technical field of flue gas environmental protection treatment. The self-stirring absorption tower comprises an absorption tower, a slurry circulation pump and a smoke inlet pipe are arranged outside the absorption tower, the slurry circulation pump is communicated with a slurry injection pipe and a slurry recovery pipe, the slurry injection pipe is located at the upper part of the absorption tower, the slurry recovery pipe is located at the bottom of the absorption tower, the side wall of the absorption tower is provided with a plurality of first disturbance plates, the first disturbance plates are annularly distributed, the bottom of the absorption tower is provided with a plurality of second disturbance plates,the second disturbance plates are annularly distributed, the second disturbance plates are perpendicular to the bottom of the absorption tower, and the opening of the slurry recovery pipe is arrangedalong the direction the same to the tangential direction of the inner wall of the absorption tower. The self-stirring absorption tower can utilizes the kinetic energy of the slurry and prevent the deposition at the bottom of the absorption tower.

Description

technical field [0001] The invention relates to the technical field of flue gas environmental protection treatment, in particular to a self-stirring absorption tower. Background technique [0002] Environmental protection is closely related to people's lives, and people's requirements for environmental protection are getting higher and higher. Flue gas purification and desulfurization must be implemented for the exhaust of factory flue gas. [0003] Therefore, the flue gas desulfurization absorption tower is a kind of equipment for purifying flue gas in most factories with flue gas discharge. At present, in the process of using the absorption tower to purify the flue gas, since the main component of the slurry used for purifying the flue gas is calcium hydroxide solution, after absorbing the sulfur-containing gas in the flue gas, calcium sulfite is easily produced, and it is easy to generate calcium sulfite at the bottom of the absorption tower. Form deposits. [0004] In ...
