Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to a desulfurization tower spray layer device. Background Art

[0002] In the wet desulfurization process, a desulfurization tower is generally used to desulfurize industrial waste gas. Several spray layers are arranged in the desulfurization tower to atomize the slurry and increase the gas-liquid contact area. However, the current spray layers all have a main pipe entering the tower and then distributed in a tree shape in the tower. Once the spray layer main pipe is blocked, the equipment needs to be shut down and maintenance personnel need to enter the desulfurization tower to clear it, which affects production, is cumbersome to operate, and has low personnel safety.

[0003] After searching, the patent number is CN214973023U, which discloses a removable desulfurization spray layer, including a spray tower. A spray layer structure is arranged inside the spray tower. The spray layer structure is composed of a fixed groove, a spray pipe and a positioning pipe. The fixed groove is fixed on the inner wall of the spray tower, the positioning pipe is fixed on the outside of the spray tower, and the positioning pipe and the fixed groove are on the same horizontal plane. A large flange is fixedly arranged on the end of the positioning pipe away from the spray tower. The spray pipe passes through the positioning pipe and is plugged into the fixed groove. The spray pipe of the spray layer structure is plugged into the spray tower and can be pulled out, avoiding the problem that the staff must enter the tower to clean when the nozzle and pipeline of the desulfurization tower are blocked, thereby improving the safety of the personnel. In addition, the spray layer structure does not need to be shut down to ventilate the desulfurization tower during maintenance, thereby saving maintenance time and reducing maintenance costs. However, when the nozzle and pipeline of the desulfurization tower are blocked, the spray pipe needs to be pulled out, and the spray pipe needs to be installed after cleaning, which is cumbersome to operate.

[0014] When a second spray pipe is blocked, the corresponding valve can be closed separately, the flange blind plates at both ends of the second spray pipe can be opened, a pipeline purge device can be connected to one flange blind plate to purge the blocked second spray pipe, and impurities can be discharged through the flange blind plate at the other end of the second spray pipe.

[0015] By setting up several groups of spray branch pipes and providing a valve on the first spray pipe, the second spray pipe can be cleaned and maintained online without stopping the operation of the desulfurization tower, which greatly reduces the risk of blockage. At the same time, the two ends of the second spray pipe are set outside the desulfurization tower. There is no need to extract the second spray pipe for blowing. It can be directly connected to the pipeline blowing device to discharge the impurities in the second spray pipe out of the desulfurization tower, and it is also avoided to discharge the impurities into the desulfurization tower for secondary cleaning. The operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS
