Abstract
Disclosed is a steam temperature and pressure reducing device. High-temperature and high-pressure steam enters a steam mixer via a steam inlet valve, a steam pressure-reducing regulating valve and a steam valve sequentially, cooling water enters the steam mixer via an inlet flange ball valve, a cooling water regulating valve and a check valve, and the steam and the cooling water which are mixed in the steam mixer are outputted to a steam using point via a mixer outlet. The steam pressure-reducing regulating valve and the cooling water regulating valve are controlled by reduced pressure and temperature respectively, so that temperature and pressure of the high-temperature and high-pressure steam are reduced to be suitable for use.
Description
Technical field
The utility model belongs to chemical machinery, particularly Desuperheating and decompressing device for steam.
Background technique
In industrial processes, usually can produce the steam of HTHP, because the restriction of pressure and temperature can not directly use, so that many occasions waste steam, extremely serious situation even have an accident.This device can improve the Steam Recovery rate with the high temperature and high pressure steam pressure and temperature reducing to being fit to the state that other equipment use, and has avoided the excess waste of resource.
Summary of the invention
The utility model technical problem to be solved is: with the condition of high temperature and high pressure steam pressure and temperature reducing to suitable use.
The technological scheme of the utility model is: valve, steam decompression valve, steam valve get into steam mixer to high temperature and high pressure steam through the steam inlet successively; Cooling water gets into steam mixer through inlet flange ball valve, cooling sea water regulating valve, safety check, exports steam to by mixer outlet after steam mixes with cooling water in steam mixer and makes use;
The PT102 pressure transducer connects the PICA102 pressure controller; The PICA102 pressure controller connects the PY positioning work piece; The PY positioning work piece connects the PV modulating valve through pneumatic actuator; The TT102 temperature transducer connects the TICA102 temperature controller, and the TICA102 temperature controller connects the TY positioning work piece, and the TY positioning work piece connects the TV modulating valve through pneumatic actuator; Instrument air is connected to positioning work piece through ball valve, exports the pneumatic actuator of modulating valve to by positioning work piece;
The pressure and temperature reducing pipeline is provided with the PT102 pressure transducer, PI101～PI102 pressure-display instrument, TT102 temperature transducer, TI101～TI102 temperature display meter.
The utility model effect is:
