Description
Technical field
The utility model relates to the control device of conduction oil temperature in a kind of temperature control equipment, particularly hydrogen production units by carbinol.
Background technology
At present, the methyl alcohol of usining of industrial application mainly contains three kinds as the approach of primary raw material hydrogen manufacturing: Methanol Decomposition, methyl alcohol partial oxidation and methanol steam reforming, the common feature of these three kinds of techniques is all need under hot conditions, carry out, and hot conditions is substantially all used conduction oil to supply with heat, and the stability of conduction oil temperature will directly affect the quality of gas product.Current conduction oil is heated by conveyance conduit and is entered hydrogen production units by carbinol by heating furnace, and the conduction oil of lowering the temperature afterwards all enters heating furnace through return line and again heats.The control of this kind of method temperature is mainly to control at furnace outlet place, the variation of formation temperature that is bound to after long-distance is carried, thus make the conduction oil temperature that enters hydrogen from methyl alcohol reactor occur fluctuation, affect hydrogen from methyl alcohol efficiency.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides conduction oil temperature control device of oil in a kind of hydrogen production units by carbinol, and it is simple in structure, temperature automatically controlled, and temperature-controlled precision is high.
The technical scheme in the invention for solving the technical problem is: conduction oil entrance communicates with the inlet seal of hydrogen production units by carbinol reactor by pipeline, inlet non-return valve, and the outlet of reactor communicates with conduction oil exit seal by outlet non-return valve; On pipeline between described inlet non-return valve and reactor, be serially connected with pneumatic control valve and temperature-measuring control device, temperature-measuring control device is controlled the aperture of pneumatic control valve; The two ends of described reactor also connect circulating pump, the import serial connection filter of circulating pump, circulation delivery side of pump serial connection circulating pump check-valves.
The utility model can be by the automatic control of point for measuring temperature and pneumatic control valve, and the deviation of temperature can accurately be controlled at ± 1 ℃, and the use of circulating pump also can avoid in reactor and pipeline conduction oil flow velocity slow and form carbon distribution.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
The specific embodiment
As shown in Figure 1, conduction oil entrance 1 communicates with the inlet seal of hydrogen production units by carbinol reactor 9 by pipeline, inlet non-return valve 2, and the outlet of reactor 9 communicates with conduction oil outlet 12 sealings by outlet non-return valve 11; On pipeline between described inlet non-return valve 2 and reactor 9, be serially connected with pneumatic control valve 3 and temperature-measuring control device 7, temperature-measuring control device 7 is controlled the aperture of pneumatic control valve 3; The two ends of described reactor 9 also connect circulating pump 6, the import serial connection filter 4 of circulating pump 6, the outlet serial connection circulating pump check-valves 5 of circulating pump 6.
The two ends of described reactor 9 also connect by-passing valve 8.
When temperature-measuring control device 7 temperature need temperature lower than reactor 9, pneumatic control valve 3 can be opened certain aperture, make to enter higher than the conduction oil of reactor 9 temperature, now the interior unnecessary lower temperature conduction oil of reactor 9 can flow out through check-valves 11, with this, reaches the object that increases reactor 9 temperature.
Adopt the utility model can the automatic control with pneumatic control valve 3 by temperature-measuring control device 7, the deviation of temperature can accurately be controlled at ± and 1 ℃.The use of circulating pump also can avoid conduction oil flow velocity in reactor 9 and pipeline to form slowly carbon distribution.
