For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0031] The utility model provides a flower-shaped mixer, such as Figures 1 to 9 As shown, it comprises a housing 1 and a pattern mixing assembly 2; two mutually parallel transverse support rods 11 and two mutually parallel longitudinal support rods 12 are arranged in the housing 1; the transverse support rods 11 and the longitudinal support rods 12 intersect to form an intersection 13; the pattern mixing assembly 2 is provided with four groups and respectively arranged at the intersection 13;

[0032] The flower pattern mixing component 2 includes a first guide plate 21, a second guide plate 22, a third guide plate 23 and a fourth guide plate 24 which are connected in sequence; the first guide plate 21, the second guide plate 22, the third guide plate 23 and the fourth guide plate 24 are arranged equidistantly around the intersection point 13 and make the flower pattern mixing component 2 circular in the upper and lower projection directions; the first guide plate 21, the second guide plate 22, the third guide plate 23 and the fourth guide plate 24 are placed obliquely relative to the horizontal plane; the first guide plate 21, the second guide plate 22, the third guide plate 23 and the fourth guide plate 24 surround a swirl cavity 25 and a guide gap 26 is formed between two adjacent guide plates.

[0033] Based on the above structural setting, the flue gas enters the cyclone chamber 25 from the guide notch 26 along the first guide plate 21, the second guide plate 22, the third guide plate 23 and the fourth guide plate 24 respectively and forms a rotating upward airflow in the cyclone chamber 25. The rotating upward airflow can prolong the residence time of the flue gas in the desulfurization tower and enhance the mixing effect, providing a longer contact time for the desulfurizer and the flue gas, ensuring that the desulfurizer and the flue gas are fully mixed, and improving the desulfurization efficiency.

[0034] In this embodiment, in two adjacent groups of flower-shaped mixing components 2, the first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 of one group of flower-shaped mixing components 2 are arranged equidistantly around the intersection 13 in the clockwise direction, and the first guide vane 21, the second guide vane 22, the third guide vane 23 and the fourth guide vane 24 of the other group of flower-shaped mixing components 2 are arranged equidistantly around the intersection 13 in the counterclockwise direction; the two adjacent groups of flower-shaped mixing components 2 respectively use guide vanes arranged clockwise and counterclockwise, which can make the flue gas produce complementary flow patterns in adjacent areas, which is conducive to more complete mixing of flue gas and desulfurizer.

[0040] In this embodiment, the contour of the top connecting surface 211 includes a first outer connecting oblique section 2111, a second outer connecting oblique section 2112, an outer guiding arc section 2113 and an outer guiding flat section 2114 connected in sequence; the contour of the bottom surface 216 includes a first inner connecting oblique section 2161, a second inner connecting oblique section 2162, an inner guiding arc section 2163 and an inner guiding flat section 2164 connected in sequence; the angle between the first outer connecting oblique section 2111 and the second outer connecting oblique section 2112 and the angle between the first inner connecting oblique section 2161 and the second inner connecting oblique section 2162 are both 125°, and the angle between the first outer connecting oblique section 2111 and the outer guiding flat section 2114 and the angle between the first inner connecting oblique section 2161 and the inner guiding flat section 2164 are both 135°.
