Special spray head for cleaning of towers

Abstract

The invention discloses a special spray head for cleaning of towers. The spray head comprises a cylindrical spray head body, wherein a through hole is formed in the spray head body in the axial direction, spray holes are formed in one end of the spray head body, the other end of the spray head body is connected with a spray gun rod, and the through hole is communicated with the spray gun rod; and at least two nozzles are arranged on the outer wall of each side of the spray head body, the nozzles are on the same circumference of the outer wall of the spray head body, and an included angle alpha formed by the center line of each nozzle and the center line of the spray head body is 25 degrees. By means of the spray head, accumulated dirt particles can be washed away quickly, all parts inside tower walls can be cleaned comprehensively, and dead corners can be avoided.

Description

technical field [0001] The invention relates to a spray head, in particular to a special spray head for cleaning a sealed ammonia distillation tower, and belongs to the technical field of chemical cleaning equipment. Background technique [0002] In the coking industry, the cast iron tower - ammonia distillation tower is generally used at present to process ammonia water and distill ammonia gas. In the prior art, the ammonia distillation tower has a height of about 20 meters and a cylindrical sealed tower body weighing about 70 tons. There are 32 trays inside, and each tray has 59 bubble cap heads. The process principle is to use high-temperature steam to enter from the middle of the tower, and diffuse to the top of the tower through the bubble cap of each layer of trays. Flowing, when the high-temperature steam and ammonia water meet at the tray, they are distilled to form ammonia gas, which is sent to the ammonia decomposition furnace for combustion and decomposition from...

AI Technical Summary

Problems solved by technology

When ammonia water passes through the tray, solid waste mixed with tar and coke particles will remain on the tray. After years of use, more and more scales will accumulate on the tray, which will gradually block the steam outlet of the bubble cap and cause ammonia gas. The amount of distillation has been greatly reduced, the flow of ammonia water is unstable, the failure rate of pump equipment for treating ammonia distillation wastewater has increased, and the trays of the ammonia distillation tower need to be cleaned urgently to improve the efficiency of ammonia distillation

[0003]The traditional method of cleaning the ammonia distillation tower is to gradually clean the trays after the ammonia distillation tower is disassembled. This cleaning method requires the disassembly of the equipment, so the operation is difficult , long maintenance period and high cost
