The water spray holes in the water spray hole group are distributed according to the sine curve, so that the water spray holes spray water continuously, the atomization effect is better, the influence on the service life of a nozzle under the interaction of high-temperature steam on high-pressure desuperheating water in the existing steam desuperheating process can be solved, and the water spray hole group can be widely popularized and applied to desuperheating systems of steam pipe networks of power stations and power stations.
Because the sine curve is composed of at least one group of wave crest sections and one group of wave trough sections, in order to facilitate the manufacture of the water jet hole groups, the water jet holes in each group of the water jet hole groups form the sine curve composed of at least two parts of wave crest parts and wave trough parts. One part of the water spray holes in the water spray hole group form a crest part, the other part of the water spray holes form a trough part, and a sine curve is formed by the two parts.
Further, the wave crest part and the wave trough part are arranged in a central symmetry mode.
In order to facilitate maintenance, furthermore, a plurality of nozzles are detachably mounted on the body, and the water spraying holes are formed in the nozzles. Through demountable installation nozzle on the body to the hole for water spraying is seted up on the nozzle, just so is inclined to carry out the later maintenance to the hole for water spraying.
Further, a plurality of groups of water spray holes are arranged along the axial direction of the conveying channel.
The invention has the beneficial effects that: when the sleeve of the temperature-reducing water spray holes distributed in the sine curve is used, the water spray holes in the water spray hole group are distributed according to the sine curve, so that the water spray holes continuously spray water, the atomization effect is better, the influence on the service life of the nozzles under the interaction of high-temperature steam on high-pressure temperature-reducing water in the existing steam temperature-reducing process can be solved, the sleeve can be widely popularized and applied to temperature-reducing systems of steam pipe networks of power stations and power stations, and the problems that in the existing temperature-reducing process of high-temperature high-pressure steam, most nozzles are single nozzles, each nozzle sprays water in a single hole, the atomization effect is poor, hardenability damage is easily caused to a chromium-molybdenum steel pipeline, the pipeline has cracks, the wall thickness is reduced, and the like, and the potential safety hazard is very large are solved.
