technical field

The invention relates to the technical field of sleeves, in particular to a sleeve of temperature-reducing water spray holes with sinusoidal distribution.

Background technique

In the process of temperature reduction of the existing high temperature and high pressure steam, most of the nozzles are single nozzles, each nozzle sprays water with a single hole, the atomization effect is not good, and it is easy to cause hardenability damage to the chrome molybdenum steel pipeline, causing cracks in the pipeline and wall. Risks such as thickness and thinning are very high security risks.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is: in order to solve the temperature reduction process of the existing high temperature and high pressure steam, most of the nozzles are single nozzles, each nozzle sprays water with a single hole, the atomization effect is not good, and it is easy to cause damage to the chrome molybdenum steel pipeline. Hardenability damage causes the risk of cracks in the pipeline and thinning of the wall thickness, and the potential safety hazard is very large. Now, a sleeve with a sinusoidal distribution of desuperheating water spray holes is provided.

The technical solution adopted by the present invention to solve the technical problem is as follows: a sleeve of desuperheating water spray holes with sinusoidal distribution, including a main body, one end of the main body is provided with a conveying channel, and the main body is provided with several groups and The water spray hole groups communicated with the conveying channel, each group of the water spray hole groups is composed of a plurality of water spray holes, and the water spray holes in each group of the water spray hole groups are distributed in a sinusoidal curve.

By arranging the water spray holes in the water spray hole group according to a sinusoidal curve, the invention makes the water spray holes spray water continuously, and the atomization effect is better. Under the interaction, the influence on the life of the nozzle can be widely used in the desuperheating system of the steam pipe network of the power station and the power station.

Since 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 spray hole group, further, the water spray holes in each group of the water spray hole group are formed at least by two wave crest sections and wave trough sections. Partially composed sine curve. A part of the water spray holes in the water spray hole group forms a wave crest part, and the other part of the water spray holes forms a wave trough part, and a sine curve is formed by the above two parts.

Further, the wave crest portion and the wave trough portion are centrally arranged symmetrically.

In order to facilitate maintenance, further, a plurality of nozzles are detachably installed on the body, and the water spray holes are arranged on the nozzles. By detachably installing the nozzle on the body, and opening the water spray hole on the nozzle, it is preferred to carry out post-maintenance to the water spray hole.

Further, several groups of water spray hole groups are axially arranged along the conveying channel.

The beneficial effects of the present invention are: when the sleeve of the temperature-reducing water spray holes with sinusoidal distribution of the present invention is in use, the water spray holes in the water spray hole group are arranged in a sinusoidal curve, so that the water spray holes continuously spray water, The atomization effect is better, which can solve the influence of the interaction of high temperature steam on the high pressure desuperheating water in the existing steam desuperheating process on the life of the nozzle, and can be widely used in the desuperheating system of the steam pipe network of the power station and power station. , to avoid the existing high temperature and high pressure steam desuperheating process, most of the nozzles are single nozzles, each nozzle sprays water with a single hole, the atomization effect is not good, and it is easy to cause hardenability damage to the chrome molybdenum steel pipeline, causing the pipeline to appear. Cracks, wall thickness reduction and other risks, the safety hazard is very big problem.
