Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form restriction to the utility model.
As shown in Fig. 1-Fig. 4, the utility model comprises some circumferentially around the nozzle assembly 2 be arranged in outside steam pipe 3, nozzle assembly 2 comprises the nozzle 2.2 of gland 2.1 and bottom, it is inner that nozzle 2.2 stretches into steam pipe 3, and side is along sealing with steam pipe 3 wall, between nozzle 2.2 and gland 2.1, both sides all arrange water inlet 2.12, and water inlet 2.12 is positioned at annular intake tunnel 4.
In technique scheme, steam pipe 3 also comprises the annular base 1 be arranged on its outer ring, and gland 2.1 is fixed on annular base 1, and annular intake tunnel 4 is formed by between annular base 1 inwall and steam pipe 3 outer wall.Annular intake tunnel 4 is communicated with filter 6 by tube connector 5, and filter 6 is communicated with desuperheating water.
In technique scheme, arranging in nozzle 2.2 can the flap 2.3 of axially-movable, spray chamber 2.6 is formed between spout 2.5 bottom umbrella part 2.4 and nozzle 2.2 bottom flap 2.3, flap 2.3 top thin bar 2.7 is through nozzle 2.2 end face, and sheathed spring base 2.8 in thin bar 2.7, sheathed spring 2.9 on spring base 2.8, and spacing by the flange 2.10 of spring base 2.8 top setting.Nozzle 2.2 end face has inclined hole 2.11, and inclined hole 2.11 one end is communicated with spout 2.5, and the other end is communicated with water inlet 2.12.Flap 2.3 thin bar 2.7 top is provided with nut 2.13 by spacing for spring base 2.8.
In technique scheme, bottom spring base 2.8 and between nozzle 2.2 top, be provided with gap n.The value of gap n is between 0.2-1.0mm.
Figure 3 shows that the utility model closed condition, now flap 2.3 closes, and umbrella part 2.4 closes with spout 2.5; Figure 4 shows that the utility model opening, now flap 2.3 axially-movable downwards, forms delivery port between umbrella part 2.4 and spout 2.5.
The utility model is under normal discharge state, desuperheating water is by the adjustable atomizing nozzle type attemperator ejection in attemperator, vaporific medium is fully atomized by primary steam high velocity air after pressure-reducing valve throttling, makes it mix with high-temperature steam rapidly, and fast velocity temperature-reducing decompressing volume is secondary Low Temperature Steam.When in primary steam pipeline, flow is in 10% ~ 30% low discharge state, cause the change of thermocouple on secondary steam pipe road, desuperheating water pipeline electric control valve is passed to through temperature transmitter, then the aperture of valve is controlled to adjust, make it to change desuperheating water pipeline flow, impel the Lift changing atomization spring nozzle, unsaturated medium is through the ejection of umbrella nozzle, make water and steam abundant mixed aerosol in mixing tube, reach the object of desuperheat.Than the nozzle of fixing existing structure, improve the atomizing effect under same steam flow, be applicable to lower steam load, expand the scope of application of steam flow.Its outlet vapor adjustable range of the reducing-and-cooling plant of new construction expands 10% ~ 100% to.In addition in running, when pressure of desuperheating water being declined suddenly in order to prevent certain reason of desuperheating water pipeline internal cause, in jet chimney, steam recoils in cooling water pipeline, therefore be the non-return structure having check function by the structural design of spring nozzle, replace the ducted check-valves of former desuperheating water.
The content that this description is not described in detail belongs to the known prior art of professional and technical personnel in the field.
