Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in figure 1, the invention relates to a double-tower U-shaped spray cooler, which comprises a front tower 1 and a rear tower 2, wherein an intermediate settling section 3 is connected between the bottoms of the front tower 1 and the rear tower 2;
the front tower 1 and the rear tower 2 are arranged along the vertical direction, and the middle settling section 3 is arranged along the horizontal direction;
the front tower 1, the rear tower 2 and the middle settling section 3 form an integral U-shaped structure;
the whole middle settling section 3 is V-shaped;
the front tower 1 comprises an upper cone 11, a middle cylinder 12 and a lower cone 13, wherein the top of the upper cone 11 is provided with a flue gas inlet 14, and the bottom of the lower cone 11 is connected with the middle settling section 3;
the height of the middle cylinder 12 is not less than 12.5 m;
a circle of spray guns 15 are arranged on the upper cone 11;
the rear tower 2 comprises an upper cylinder 21 and a lower transition section 22, a sealing plate 23 is arranged at the top of the upper cylinder 21, the bottom of the lower transition section 22 is connected with the middle settling section 3, and a flue gas outlet 24 is formed in one side of the upper part of the upper cylinder 21;
