Abstract
The utility model discloses a steam attemperation and decompression device of simple structure which abandons a secondary meter and applies to the steam of high temperature and pressure. The utility model is characterized in that a steam regulation valve is equipped at a steam sucker and connects a steam nozzle behind outside which a nozzle jacket is equipped where a water exhaust port is equipped. The nozzle jacket connects a temperature control valve equipped at a water pipe used to lower the temperature and coexists with the nozzle jacket in a mixing pipe the tail of which direct connects a vapor transmission pipeline. The utility model possesses advantages of simple structure, abandoning secondary meter and avoiding the phenomena of the vapor carrying the water.
Description
Technical field
The utility model relates to a kind of device that can carry out pressure and temperature reducing to high temperature and high pressure steam, relates in particular to the bigger occasion of steam cooling amplitude.
Background technique
The Desuperheating and decompressing device for steam that present numerous producer adopts is: depressurized system is installed pneumatic or electric control valve in main steam range, delivers to modulating valve by the pressure transmitter output signal behind the valve after regulator is handled, thereby finishes the process of lowering and stabilizing blood pressure; Temperature reducing system increases multistage raw water service pump on the basis of decompression, high pressure by water pump is gone into hydraulic pressure in the pipeline after the step-down, at the water supply delivery side of pump modulating valve is installed, linking to each other with temperature transmitter and regulator by modulating valve constitutes a temperature regulation loop, thereby guarantees temperature stabilization.
The shortcoming of the reducing-and-cooling plant of said structure is: owing to need two PID regulating loops at least, need equipment such as high-pressure water pump in addition, increased input cost on the one hand, simultaneously because being written into of electric equipment also increased many work to regular maintenance; Cooling water directly adds by high-pressure service pump in addition, because the steam temperature difference is bigger, the cooling water of Jia Ruing can not be vaporized in time sometimes, and the water entrained by steam phenomenon appears in many reducing-and-cooling plants.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, need not high-pressure water pump and electric equipment, can avoid the Desuperheating and decompressing device for steam of water entrained by steam phenomenon again.
For achieving the above object, the technical solution adopted in the utility model is: described Desuperheating and decompressing device for steam, its structure mainly comprises: be installed on the steam regulation valve on the steam inlet duct, be connected with steam nozzle behind the steam regulation valve, outer installment at steam nozzle has the nozzle chuck, nozzle clamp puts and leaves osculum, and the nozzle chuck is connected with thermostat valve on the desuperheat water pipe by pipeline; Steam nozzle and nozzle chuck all are arranged in the mixing tube, and the tail end of mixing tube directly links to each other with steam pipeline.
The further technological scheme of the utility model is: described nozzle chuck is concordant with the end of steam nozzle, and nozzle chuck and steam nozzle are arranged on the central axis of mixing tube with one heart.
The utility model has the advantages that: equipment is simple, need not secondary meter, can avoid the water entrained by steam phenomenon.
Description of drawings
Fig. 1 is the structural representation of Desuperheating and decompressing device for steam described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments technological scheme described in the utility model and working principle thereof and advantage are further described.
As shown in Figure 1, Desuperheating and decompressing device for steam described in the utility model, mainly comprise: be arranged on the steam regulation valve 1 on the steam inlet duct, steam regulation valve 1 rear end connects steam nozzle 3, nozzle chuck 5 is equipped with in steam nozzle 3 outsides, steam nozzle 3 and nozzle chuck 5 are installed on the central axis in the mixing tube 2 with one heart, the afterbody of mixing tube 2 links to each other with steam pipeline 4, nozzle chuck 5 is concordant with the end of steam nozzle 3, osculum is left in the end of nozzle chuck 5, and nozzle chuck 5 links to each other with thermostat valve 6 on the desuperheat water pipe by pipeline.During actual the use, sensing and controlling device can be set in addition: control the opening degree of steam regulation valve 1 with the variation in pressure in the steam pipeline 4, control the opening degree of thermostat valve 6 with the temperature variation in the steam pipeline 4.
Details are as follows for the working principle of the Desuperheating and decompressing device for steam of said structure: one, high temperature and high pressure steam is behind steam regulation valve 1, by steam nozzle 3 throttling step-downs, by cooling water heat absorption vaporization cooling; Two, steam pipeline 4 internal pressures act on steam regulation valve 1, open greatly or turn down to drive it, thereby the pressure in the assurance steam pipeline 4 is stable; Temperature action in the steam pipeline 4 is in thermostat valve 6, driving its increase or to reduce the cooling water flow, thereby guarantees temperature stable in the steam pipeline 4; Three, cooling water regulate through thermostat valve 6 after after 5 preheatings of nozzle chuck the easier steam that is sprayed by steam nozzle 3 vaporize; Four, steam nozzle 3 has been combined to form vapor pump with mixing tube 2, produces negative pressure and the cooling water after the preheating is sucked and mixing mixing tube 2 in.
From the above mentioned as can be known, use Desuperheating and decompressing device for steam described in the utility model, can save high-pressure water supply pump, cooling water easier vaporization under preheating and condition simultaneously in negative pressure, thus avoided the water entrained by steam phenomenon; And need not secondary meter, equipment is simpler.
Claims (2)
1, Desuperheating and decompressing device for steam, mainly comprise: be installed on the steam regulation valve on the steam inlet duct, be connected with steam nozzle behind the steam regulation valve, it is characterized in that: the outer installment at steam nozzle has the nozzle chuck, nozzle clamp puts and leaves osculum, and the nozzle chuck is connected with thermostat valve on the desuperheat water pipe by pipeline; Steam nozzle and nozzle chuck all are arranged in the mixing tube, and the tail end of mixing tube directly links to each other with steam pipeline.
