Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to an improved ammonia spray nozzle. Background Technology

[0002] The ammonia spray nozzle is a key component of the ammonia treatment system. Its design and function are crucial to the overall performance of the system, especially in ammonia refrigeration and ammonia storage spray systems and in the field of waste gas treatment.

[0003] In the field of waste gas treatment, ammonia spray nozzles are used to spray ammonia water, which reacts with nitrogen oxides in the waste gas, converting them into nitrogen and water, thereby purifying the waste gas. These nozzles are commonly used in industrial emission sources such as boilers, kilns, and incinerators, and can significantly reduce the emission concentration of nitrogen oxides. When ammonia water is sprayed through the nozzle, if the ammonia water is used in an environment with excessively low temperatures, the ammonia water remaining in the nozzle may crystallize after the circulating water pump is turned off. These crystals tend to accumulate in the narrow-diameter nozzle orifice at the end of the nozzle, thus clogging the nozzle. If the ammonia water contains impurities, and because the nozzle orifice size is small while the impurity particles are relatively large, when the liquid containing impurities flows through the nozzle, the impurities tend to stagnate and accumulate at the nozzle orifice, gradually clogging the nozzle and affecting the normal spraying function of the nozzle.
