Abstract
The utility model discloses a kind of Wen Qiulishi attemperator, aim to provide that a kind of steam flow rate is more stable, temperature lowering effect is more obvious, the attemperator that efficiency is higher.The main points of its technical scheme are, Venturi tube is provided with in mixing duct, one end that venturi diameter is larger is provided with equally distributed semi-circular through hole, the junction of Venturi tube curved segment and straight section is provided with 2 symmetrical through holes, sparge pipe is through through hole, one end is fixed on mixing duct outer wall, and the other end is fixed on Venturi tube outer wall, the pipeline section being positioned at Venturi tube is provided with the nozzle that angle is the equidistant arrangement of two rows of 40 ゜ at sparge pipe.
Description
Technical field
The present invention relates to a kind of attemperator device, particularly relate to a kind of Wen Qiulishi attemperator.
Background technology
Attemperator is used to the important device of steam regulation boiler steam temperature.In real life, the temperature of boiler export steam is often higher, now needs attemperator that the temperature of steam is reduced to OK range, in order to avoid cause damage to the equipment in downstream.Sometimes, because vapor (steam) temperature is too high, also the major accidents such as blast may be caused.
The atomizing effect of the temperature lowering effect of attemperator and injection flow rate and desuperheating water is closely related.Existing attemperator often atomizing effect is bad, and flow velocity is not high, and power consumption is large.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of Venturi tube attemperator.
The technical solution adopted in the present invention is: a kind of Wen Qiulishi attemperator, comprise mixing duct, sparge pipe, Venturi tube is provided with in mixing duct, one end that venturi diameter is larger is provided with equally distributed semi-circular through hole, the junction of Venturi tube curved segment and straight section is provided with 2 symmetrical through holes, sparge pipe is through through hole, one end is fixed on mixing duct outer wall, the other end is fixed on Venturi tube outer wall, the pipeline section being positioned at Venturi tube is provided with the nozzle that angle is the equidistant arrangement of two rows of 40 ° at sparge pipe.
Compared with prior art, the invention has the beneficial effects as follows that more stable (3) temperature lowering effect of the flow velocity of better (2) steam of the atomizing effect of (1) desuperheating water is more obvious, efficiency higher (4) is easy for installation, easy care.

Fig. 2 is sparge pipe structural representation;
Fig. 3 is A-A face left view;
Fig. 4 is A-A face right view;
Fig. 5 is Venturi tube left view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
A kind of Wen Qiulishi attemperator, comprise mixing duct 3, sparge pipe 1, it is characterized in that: in mixing duct 3, be provided with Venturi tube 2, one end that Venturi tube 2 diameter is larger is provided with equally distributed semi-circular through hole 5, the junction of Venturi tube 2 curved segment and straight section is provided with 2 symmetrical through holes, sparge pipe 1 is through through hole, one end is fixed on mixing duct 3 outer wall, the other end is fixed on Venturi tube outer wall 2, and the pipeline section being positioned at Venturi tube 2 at sparge pipe 1 to be provided with angle be two trestle column of 40 ° is the nozzle 4 of 8mm.
Embodiment 1.Steam enters Venturi tube 2 from mixing duct 3, and because Venturi tube 2 has the effect of vibration-inhibition, therefore steam is comparatively steady, and compatible with the desuperheating water sprayed from nozzle 4, desuperheating water is vaporized by the high temperature that steam carries, and the temperature of steam self declines simultaneously.Because the angle two of nozzle arranges design, the desuperheating water sprayed can fully be contacted with steam, and the desuperheating water of the overwhelming majority is vaporized, and the temperature of steam is also reduced to rapidly suitable value.
