Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1-2, the Y-pipe distributor for the PSR polymer denitration system of this embodiment includes a flared pipe 2, a base 6, and branch pipes 7 that are sequentially communicated, the flared pipe 2 is disposed at the front end of the base, the branch pipes 7 are uniformly disposed at the rear end of the base 6, and flow guide cores 3 are disposed inside the flared pipe 2 and the base 6;

an inlet flange 1 is arranged at the inlet of the flared tube 2, and a flared tube flange 4 is arranged at the outlet of the flared tube 2;

a base flange 5 matched with the flared pipe flange 4 is arranged at the inlet of the base 6; the flared tube 2 and the base 6 are connected with a base flange 5 through a flared tube flange 4.

The flaring pipe 2 and the base 6 of distributor are connected with the base flange 5 through the flaring pipe flange 4, when the distributor is inside to appear blockking up, can separate the flaring pipe 2 and the base 6 to clear up the distributor is inside, make the maintenance of distributor more convenient.

The flared pipe 2 is butted with the PSR main pipeline through the inlet flange 1.

The inlet flange 1 is in butt joint with the PSR main pipeline, so that the distributor and the main pipeline can be quickly installed and disassembled.

The base 6 with flared tube 2 is circular structure, just the entry pipe diameter of base 6 with flared tube 2's export pipe diameter's size is the same.

The flaring pipe 2 and the base 6 of distributor all adopt circular structure for the inside no right angle blind spot of distributor effectively avoids the blind spot of denitration powder in the distributor to harden.

The transition wall between the inner wall surface of the rear end of the base 6 and the side wall thereof is a circular truncated cone side wall.

The inner wall surface of the rear end of the base 6 is in transition with the side wall of the base 6 through the circular truncated cone side wall, so that powder is not easy to accumulate on the base 6, and the powder discharging efficiency of the base 6 is improved.

The pipe diameter of the flaring pipe 2 gradually increases from the inlet to the outlet.

Through the change of the pipe diameter of the flared pipe 2, the powder moving at high speed is sprayed to a larger pipe diameter from a smaller pipe diameter, so that the powder can be better dispersed in the distributor.

The rear part of the flow guide core 3 is a cylinder core 31, the front part of the flow guide core 3 is a cone core 32, and the rear part of the flow guide core 3 is welded and fixed in the middle of the inner wall surface of the rear end of the base 6.

Through with water conservancy diversion core 3 welded fastening on base 6 for water conservancy diversion core 3 has very strong stability, and is not fragile.

The cylinder core 31 is an equilateral triangular cylinder, and the side plane of the cylinder core 31 is tangent to the interface of the branch pipe 7.

Through the design, dust can be better dispersed into each group of branch pipes 7, so that the powder dispersing effect is better.

The cone core 32 is an equilateral triangular cone, the bottom surface of the cone core 32 is flush with the outlet of the flared tube 2, and the top point of the cone core 32 is located at the center of the inlet flange 1.

The cone core 32 is arranged in the flared pipe 2 on the distributor, so that a streamline structure is formed inside the flared pipe 2, the uniform distribution of powder in the distributor is realized, and meanwhile, the resistance of the cone core 32 during the distribution of the powder can be reduced, and the conveying efficiency of the powder is improved.

The number of the branch pipes 7 is three, and an included angle A between each branch pipe 7 and the pipeline axis of the flared pipe 2 is 20 degrees.

The included angle A between each branch pipe 7 and the pipeline axis of the flaring pipe 2 is 20 degrees, so that the denitration agent is effectively prevented from being accumulated and blocked at the corner part due to overlarge steering angle, and the denitration agent is uniformly distributed.

And a branch pipe flange 8 is arranged at the outlet of the branch pipe 7.

Through set up branch pipe flange 8 in 7 exits of branch pipe for the distributor can realize quick installation with deNOx systems and dismantle.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention.
