Problems solved by technology
The nozzle has the following problems in the production process: 1. Since the nozzle slots used in the production of different grades of products are of different sizes, it is very cumbersome to prepare several nozzles with different slot sizes for replacement; 2. Due to the The middle tubular reactor has a certain pressure, the notch is prone to deformation, and the damage rate is high; 3. Because the nozzle wall is thin, the notch is not easy to be chamfered, and the effect of atomization and granulation is poor

Abstract
The invention relates to an improved tubular reactor spray nozzle used for production of compound fertilizer. The improved tubular reactor spray nozzle comprises a tube, one end of the tube is connected with a tubular reactor, a notch used for spraying paste is formed axially in the tube, a base which is welded to the notch and a spraying part installed on the base are arranged on the outer wall of the tube, a slurry spraying hole corresponding to the notch is formed in the base, and a slurry spraying opening corresponding to the slurry spraying hole is formed in the spraying part. The improved tubular reactor spray nozzle can be used for producing products of different grades by replacing spraying parts with different slurry spraying openings, it is not needed to replace the whole stainless tube, and therefore the time for replacing spray nozzle is substantially shortened. Due to the fact that the base and the spraying part are additionally installed at the notch in the tube, the intensity of the notch in the tube is improved, deformation is avoided, and the damage rate is greatly decreased; in addition, the slurry spraying opening in the spraying part is easy to chamfer, and a good atomizing granulating effect is easy to achieve.
Description
technical field [0001] The invention relates to the field of compound fertilizer production equipment, in particular to an improved tubular reactor nozzle. Background technique [0002] At present, compound fertilizers are produced in tubular reactors and then sprayed into the granulation cylinder through nozzles to realize granulation. The nozzles are made of stainless steel pipes with a specification of DN125*935 and a thickness of 6mm. One end of the stainless steel pipes passes through the method The flange is connected with the tubular reactor, and the other end is sealed with a blind plate. There is a notch arranged in the axial direction and used for spraying on the stainless steel tube, such as figure 1 shown. The nozzle has the following problems in the production process: 1. Since the nozzle slots used in the production of different grades of products are of different sizes, it is very cumbersome to prepare several nozzles with different slot sizes for replacement...
