Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 and 2, a waste gas treatment system of a fertilizer production line comprises a waste gas pipeline 1 and a separator 2, wherein the waste gas pipeline is connected to the bottom of the separator 2 through a reducer pipe, the reducer pipe is provided with an inlet section 3, a contraction section 4, a throat pipe 5 and a diffusion section 6 which are sequentially connected, the inlet section 3 is connected with the waste gas pipeline 1, the diameter of the inlet section corresponds to that of the waste gas pipeline 1, the contraction section 4 is gradually reduced in diameter and is connected with the throat pipe 5, the rear end of the throat pipe 5 is connected with the diffusion section 6, the diffusion section 6 is directly and gradually increased and is connected with the separator 2, and an adjusting plate 7 is arranged inside the diffusion section 6; an air outlet 8 is formed in the top of the separator 2, a water outlet 9 is formed in the bottom of the separator, the water outlet 9 is connected with a water drain pipe 10, the other end of the water drain pipe 10 is connected to a sedimentation tank 11, the sedimentation tank 11 is conical, a sewage discharge pipeline 12 is formed in the bottom of the sedimentation tank, a sewage discharge valve 13 is arranged on the sewage discharge pipeline 12, an annular clean water tank 14 is arranged on the outer ring of the top of the sedimentation tank 11, the clean water tank 14 is communicated with the sedimentation tank 11 through an overflow groove, a clean water discharge port is formed in one; a water pump 15 is arranged on one side of the water tank 16, and the output end of the water pump 15 is connected to the throat pipe 5.
