Detailed Description

The utility model is described in detail with the attached drawings, as shown in the figure, the utility model comprises a spraying device 1, an outer sleeve 2, an inner sleeve 3, a front chamber 4, a front chamber spraying device 5, an acid remover 6, a rear chamber spraying device 7, a rear chamber 8, an annular distribution chamber 9, a coal gas inlet 10, a coal gas outlet 11 and a mother liquor inlet 12;

the outer sleeve 2 and the inner sleeve 3 are arranged concentrically, the upper part of the outer sleeve is circumferentially provided with a first partial arc 21, and a front chamber 4 is arranged between the outer sleeve and the inner sleeve 3 of the first partial arc 21; the upper circumference of the outer sleeve 2 at the other side corresponding to the front chamber is a second partial arc 22, and a rear chamber 8 is arranged between the second partial arc 22 and the inner sleeve 3; the lower parts of the front chamber and the rear chamber are connected through the lower space of an annular distribution chamber 9 formed between the outer sleeve 2 and the inner sleeve 3, and a spraying device 1 is arranged in the annular distribution chamber 9; the upper end of the interior of the front chamber is provided with a front chamber spraying device 5, and the side part of the front chamber is provided with a coal gas inlet 10; the upper part of the rear chamber is provided with a rear chamber spraying device 7; the upper part of the inner cylinder 3 is provided with an acid remover 6, and the acid remover 6 is communicated with the rear chamber;

the spraying device 1 comprises an annular support plate 13, and a plurality of nozzles 14 uniformly distributed along the circumferential direction are arranged on the support plate 13; the nozzle comprises an outer wall 121 and a conical inner wall 122, and a plurality of groups of spiral channels 123 are arranged between the outer wall and the inner wall;
