Abstract
The utility model discloses a steam conduit voltage regulator device, including the main steam pipe way, be equipped with a steam pressure measurement adjusting device and a blowdown piping on the pipeline that main steam pipe said, the blowdown piping includes a pneumatic control valve, and pneumatic control valve's export divides two the tunnel, is compressed air pipe all the way, and another way is the air hose, steam pressure measures adjusting device including setting up a pressure transmitter and the intelligent PID regulator on main steam pipe says, pressure transmitter's the sensing signal and the control system of intelligent PID regulator are connected, and the actuating signal of intelligent PID regulator is connected with pneumatic control valve's control system. This practical simple structure, cost of manufacture are low, and the unstable problem of solve hydrometallurgy steam prolongs valve positioner life simultaneously, the great working strength who has alleviateed operating personnel.
Description
Technical field
The utility model relates to metal smelt field, particularly relates to the stable-pressure device in wet smelting process middle steam tube road.
Background technique
At present in wet smelting process, steam provide two kinds of modes, one is that another kind of mode is that the waste heat utilizing various metallurgical furnace to produce heats with combustion gas or other fuel burning boilers for wet method provides thermal source.But in main steam header road, the pressure of steam is often in an unsure state, need the supply by regulating the steam producing steady pressure to carry out factory steam further, in existing technology, the general Self-operated pressure reducing valve that adopts controls vapor pressure, but when steam consumption changes greatly time, often requirement can not be reached to the adjustment of steam, the problem that build-up of pressure fluctuation is larger, and whole process need has the operator of specialty on the scene, this adds the working strength of operator undoubtedly.
Model utility content
The purpose of this utility model is the deficiency optimizing existing production technology, adapts to reality need, provides a kind of steam line stable-pressure device.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of steam line stable-pressure device, comprise main steam line, the pipeline of main steam line is provided with vapor pressure measuring and adjusting device and a blowdown piping, described blowdown piping comprises a pneumatic control valve, the outlet of pneumatic control valve divides two-way, one tunnel is compressed air hose, another road is air duct, described vapor pressure measuring and adjusting device comprises and is arranged on pressure transmitter on main steam line and an INTELLIGENT PID REGULATOR, the induced signal of described pressure transmitter is connected with the control system of INTELLIGENT PID REGULATOR, the actuating signal of INTELLIGENT PID REGULATOR is connected with the control system of pneumatic control valve.
Described blowdown piping is also provided with valve positioner, and pneumatic control valve is arranged on valve positioner.
The pipeline of described compressed air line is provided with damping device, is provided with automatic water trap in the bottom of damping device.
This practical structure is simple, fabricating cost is low, solves the problem of hydrometallurgy steam instability, extends valve positioner working life simultaneously, alleviates the working strength of operator greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, main steam line 1, air duct 2, compressed air hose 3, INTELLIGENT PID REGULATOR 4, pressure transmitter 5, pneumatic control valve 6, valve positioner 7, damping device 8, automatic water trap 9.
Embodiment
