The invention discloses an air injection spray nozzle of a dry-process slag quenching device. The air injection spray nozzle is mainly used for blowing air to cool slag inside a pelletization furnace and comprises a rotary table, a supporting shaft, a support, an upper end closure and a lower end closure, wherein the rotary table is connected to the supporting shaft through a sunk screw and can be of an integral structure; fins are uniformly arranged at the lower side of the rotary table, and 45-degree included angles are formed between the line formed by intersection points of the fins and the outer circle of the rotary table and the fins; cooling air enters the spray nozzle from the lower side of the spray nozzle, and then enters the pelletization furnace so as to cool pelletized hot slag in the pelletization furnace and meanwhile enhance pelletization, meanwhile the cooling air drives the rotary table to rotate through the fins, and when the slag falls on the rotary table, the slag is centrifugally tossed out, so that the cooling of the hot slag is accelerated; and the area of the rotary table is larger than that of the support, so that the rotary table has a protection effect on the whole spray nozzle and meanwhile avoids the blockage of the spray nozzle. The air injection spray nozzle is simple in structure and easy to manufacture and has very good economic benefit.
Description
technical field [0001] The invention relates to an air jet nozzle of a dry slag quenching device, which belongs to the field of dry slag quenching equipment. Background technique [0002] With the growth of the world's steel demand and the development of the steel industry, the discharge of blast furnace slag is increasing day by day. If the blast furnace slag is not treated as a resource, it will not only be a huge waste of available resources, but also accumulate over time, which will inevitably cause a series of serious problems such as occupying land, invading fields, and polluting the environment. Therefore, the recycling of blast furnace slag can not only turn waste into treasure, but also reduce environmental pollution and land occupation, so as to achieve a win-win situation of economic and social benefits. Since the use of blast furnace slag in 1880, many countries in the world have used blast furnace slag as a secondary resource. [0003] The more advanced tech...
