Abstract
The utility model discloses one kind to save attemperator, including temperature-adjusting device, Venturi tube and damp type spiral coil, wherein：The temperature-adjusting device is used to preheat desuperheating water, enters the damp type spiral coil by pipeline by the pre-warmed desuperheating water；The damp type spiral coil is arranged on inside Venturi tube, and multiple hole for water sprayings are uniformly arranged on its helical pipe.Attemperator of the present utility model reduces desuperheating water caused temperature difference in attemperator, eliminates throttle resistance caused by Venturi tube, reduces the pressure loss, reaches the purpose of energy-conservation.
Description
【Technical field】
The utility model belongs to attemperator field, more particularly to one kind is based on the pre-warmed energy-conservation attemperator of desuperheating water.
【Background technology】
In the prior art, superheated steam introduces Venturi tube by attemperator entrance, and desuperheating water scales position in Venturi tube
Sprayed into by nozzle, vaporific desuperheating water is sufficiently mixed with flow of superheated steam, by one section of sleeve pipe, flows out attemperator.The water of penetrating with
Superheated steam carries out heat exchange and is changed into steam, reaches the purpose of superheated steam temperature reduction.
But the shortcomings that existing attemperator, is：1) the scaling mouth of Venturi tube has throttling action, has one to superheated steam
Fixed resistance, pressure drop is produced, cause the pressure loss of superheated steam.2) desuperheating water nozzle spray is excessively concentrated, and atomization will not
Uniformly, water entrained by steam phenomenon may be produced.3) temperature control stability is poor, and degree of regulation is relatively low.
【Utility model content】
In order to solve above mentioned problem of the prior art, the utility model proposes one kind to save attemperator, and this practicality is new
The technical scheme that type uses is specific as follows：
One kind energy-conservation attemperator, including temperature-adjusting device, Venturi tube and damp type spiral coil, wherein：The temperature
Degree adjusting means is used to preheat desuperheating water, enters the damp type by pipeline by the pre-warmed desuperheating water
Spiral coil；The damp type spiral coil is arranged on inside Venturi tube, and is uniformly arranged on its helical pipe multiple
Hole for water spraying.
Further, the damp type spiral coil is arranged on the entrance of Venturi tube.
Further, the damp type spiral coil is in trochoid spiral, and helical angle is 25 degree.
Further, the quantity of the hole for water spraying is no less than 10.
Further, pre-warmed temperature can be set in the temperature-adjusting device.
The beneficial effects of the utility model are：Reduce desuperheating water caused temperature difference in attemperator, eliminate Venturi tube
Caused by throttle resistance, reduce the pressure loss, reach the purpose of energy-conservation.
【Brief description of the drawings】
Accompanying drawing described herein is to be further understood for providing to of the present utility model, forms one of the application
Point, but do not form to improper restriction of the present utility model, in the accompanying drawings：
Fig. 1 is structural representation of the present utility model.
【Embodiment】
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples therein with
And explanation is only used for explaining the utility model, but it is not intended as to improper restriction of the present utility model.
Referring to accompanying drawing 1, it illustrates basic structure of the present utility model.Energy-conservation attemperator of the present utility model includes temperature
Adjusting means, Venturi tube and damp type spiral coil.
The temperature-adjusting device is used to preheat desuperheating water, and the desuperheating water after heating enters the damping by pipeline
Formula spiral coil.The damp type spiral coil is arranged on the entrance of Venturi tube, and is uniformly distributed on its helical pipe
Multiple hole for water sprayings, desuperheat is carried out to the superheated steam for entering Venturi tube by way of water spray.
During spray desuperheating, due to desuperheating water through preheating, in spray desuperheating with jet chimney caused by the temperature difference significantly
Reduce, the temperature difference causes the expansion of damp type helix tube very small, and thermal stress is also very small as caused by the temperature difference.And damp type spiral shell
Capstan pipe water spray is more uniform, and superheated steam streams outside helix tube, and flow velocity is relatively low, and the pressure loss has certain section with regard to very little
Can effect.
Preferably, the damp type spiral coil is in trochoid spiral, and helical angle is 25 degree, and the quantity of water jet is many
In 10, on this condition, more preferable energy-saving effect can be obtained.
Further, the temperature-adjusting device can also set pre-warmed temperature, and user can be according to superheated steam
Concrete condition, and current specific environment, to set specific pre-heating temperature, so as to realize rapid desuperheat, mist
Change the features such as effect is good, and temperature adjustment is sensitive, and control accuracy is high.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
The equivalent change or modification done of construction, feature and principle, be included in the utility model patent application range.
