Abstract
The utility model relates to the field of temperature and pressure reduction, in particular to a temperature and pressure reduction device for a chemimechanical pulping system in a papermaking process. The temperature and pressure reduction device comprises a temperature and pressure reduction valve, wherein the temperature and pressure reduction valve is arranged on a steam pipe and is also connected with a temperature reduction water pipe; the temperature reduction water pipe is provided with a water supply adjusting valve; a pressure transmitter is positioned on the steam pipe on the upstream of the temperature and pressure reduction valve. The temperature and pressure reduction device is quick, easy and convenient to mount and easy to operate, has a high adjustable ratio and saves the operation and maintenance cost.
Description
Technical field
The utility model relates to pressure and temperature reducing field, relates in particular to a kind of reducing-and-cooling plant for papermaking operation machine slurry system.
Background technique
At present the known Desuperheating and decompressing device for steam for vital qi supply system is to utilize the throttling of vapor stream to realize the object that reduces vapor pressure, utilizes the object that realizes cooling to water spray in steam.Although adopt custom-designed decompression, cooling system, but be all to exist complex structure, the complicated problem of system, in throttling, producing high energy jet not only fails to be used effectively on the contrary with its high slight power generation to the erosion damage of structure and vibration and noise, the defect usually existing because of existing design in desuperheat water spray process, when device low-load, atomizing effect is bad, the larger water droplet that existence can not be evaporated rapidly.
Summary of the invention
The purpose of this utility model is in order to provide a kind of simple in structure, easy to operate, to control accurate reducing-and-cooling plant.
The technological scheme that the utility model provides is:
Reducing-and-cooling plant, comprises steam converter valve, and steam converter valve is arranged on steam tube, and described steam converter valve also connects desuperheat water pipe, on described desuperheat water pipe, is provided with feed-regulating valve, and pressure transmitter is positioned on the steam tube of steam converter valve upstream.
Concrete, described pressure transmitter is also connected with pressure digital display instrument.
Concrete, described steam converter valve outlet port is provided with humidostat, and humidostat connects controls feed-regulating valve.
It is accurate, stable that the utility model high-precision pressure transmitter, humidostat can guarantee to regulate parameter; Energy-efficient, the quality of steam of adjusting is stable, can improve heat transmission equipment or manufacturing mechanism efficiency, energy saving.The utility model is installed fast and convenient, simple to operate; There is high regulating ratio, save operation and maintenance cost.
Accompanying drawing explanation
Fig. 1 is that this uses novel structural representation.
