The desulfurization absorption tower sprays limestone slurry through a nozzle and mixes it with the flue gas to desulfurize. After the desulfurization absorption tower is shut down, there will be residual limestone slurry in its branch pipe, which will gradually condense and cause the nozzle to be blocked, affecting subsequent use.

Both sides of each water branch pipe are connected to a water spray pipe, and the water spray port of the water spray pipe faces the nozzle.

[0008] In the desulfurization absorption tower spray layer cleaning device, the main water pipe is connected to the water outlet of the water pump, and the water inlet of the water pump is connected to the water tank.

[0009] The desulfurization absorption tower spray layer cleaning device is characterized in that the water spray pipe is an L-shaped pipe, and the water outlet end thereof has an oblique cut. Beneficial effects

[0010] 1. The utility model is connected with the main water pipe through the main liquid pipe. After the machine is shut down, the water in the water tank is pumped into the main liquid pipe, then passes through the branch pipe and the spray pipe, and finally sprayed out through the nozzle, which can clean out the residual limestone slurry and prevent condensation.

[0011] 2. The utility model sets a water distribution pipe, which is connected to a water spray pipe. When water is passed through, part of the water will enter the water distribution pipe, then pass through the water distribution pipe, and finally be sprayed out through the water spray port of the water spray pipe. The water spray port faces the nozzle, and water can be sprayed on the nozzle to clean the limestone slurry adhered to it, thereby preventing the nozzle from being blocked due to adhesion after long-term use.

[0018] Reference Figure 1-Figure 5 A desulfurization absorption tower spray layer cleaning device, comprising: a tower body 3, a spray layer fixed in the tower body, through which limestone slurry is sprayed and mixed with flue gas to achieve flue gas desulfurization, the spray layer including a main liquid pipe 2, a plurality of branch pipes 7 are evenly distributed on both sides of the main liquid pipe, and each of the branch pipes has a plurality of spray pipes 6 at both ends, and each of the spray pipes is fixed with a nozzle 13;

[0019] The spraying method is to introduce limestone slurry into the main liquid pipe, and the limestone slurry will enter each spray pipe through the branch pipe, and finally be sprayed out through the nozzle on each spray pipe;

[0020] The input end of the main liquid pipe is connected to a tee 1, and the tee is connected to the main water pipe 10;

[0021] The main water pipe is connected to a water pipe 5, and the two sides of the water pipe are connected to multiple water branch pipes 11 opposite to the branch pipes. Each of the water branch pipes is connected to a water spray pipe 4 on both sides, and the water spray port 14 of the water spray pipe faces the nozzle.

[0022] When the spray layer needs to be cleaned after shutdown, water is introduced. The water enters the main liquid pipe through the main water pipe, then enters each spray pipe through the branch pipe, and finally sprays out through the nozzle on each spray pipe. In this way, the water can mix with the residual limestone slurry and spray out together to clean the residual slurry in it;

[0023] In the desulfurization absorption tower spray layer cleaning device, the main water pipe is connected to the water outlet of the water pump 8, and the water inlet of the water pump is connected to the water tank 9.

[0024] While cleaning the limestone slurry in the spray layer pipe, a portion of the water will enter the water pipe through the main water pipe, then enter the water distribution pipe, and finally be sprayed out through the water nozzles of each spray pipe. The sprayed water will be sprayed onto the nozzle, so that the limestone slurry stuck to the outside of the nozzle can be washed away to prevent the nozzle from being blocked;

[0025] In the desulfurization absorption tower spray layer cleaning device, the water spray pipe is an L-shaped pipe with an oblique cut 15 at its water outlet end. The bottom of the water spray pipe is higher than the nozzle. The water spray pipe is tilted downward, and its water spray port is facing the nozzle. The oblique cut can prevent the water spray port from directly facing the flue gas, thereby preventing the flue gas from entering and gradually clogging the water spray port, thereby ensuring the smooth flow of the water spray port.

[0026] Working principle: When the machine stops after spraying at each spray layer, start the water pump, and a valve 12 is installed on the main water pipe. When the valve is opened, the water in the water tank will enter the main liquid pipe through the main water pipe under the action of the water pump, and some water will enter the water pipe. The water entering the main liquid pipe enters each spray pipe through the branch pipe, and finally sprays out through the nozzle on each spray pipe. In this way, the water can mix with the residual limestone slurry in it and spray it together to clean the residual slurry in it;

[0027] The water entering the water pipe will enter the water distribution pipe and eventually be sprayed out through the water outlets of each spray pipe. The sprayed water will be sprayed onto the nozzle, which can wash away the limestone slurry stuck on the outside of the nozzle and prevent the nozzle from being blocked.
