Abstract
This invention relates to the application of the magnetic valve in the hydrogen making device, the level transmitter and piezo-electric pick-up are arranged on the hydrogen separator (1) and oxyen separator (2)of the electrolyzation hydrogen making device, the temperature sensor is arranged on the alkali lye coolant tube, after being controlled by PLC, the level gas-filled film regulating valve, the pressure gas-filled film regulating valve, the temperature gas-filled film regulating valve starting doing the control of liquid level, pressure and temperature. The charater is that the level gas-filled film regulating valve, the pressure gas-filled film regulating valve, the temperature gas-filled film regulating valve are replaced by the level magnetic valve, the pressure magnetic valve and the temperature valve respectively. The advantage of this invention is that it doesn't need instrument gas, and the volume of the magnetic valve is small, which is convenient for the high integration of the complexes.
Description
(1), technical field
The invention belongs to the application of magnetic valve in device for producing hydrogen.
(2), background technology
In water electrolysis hydrogen producing equipment, three (generally also having only three) important analog quantity reference mark are arranged, be respectively pressure, liquid level and temperature.Up to the present, all be to adopt pneumatic diaphragm control valve as the topworks that regulates, the principle sketch of control is as shown in Figure 1.Among the figure: 1-hydrogen separator, 2-oxygen separator, J1-by-pass valve, the J2-by-pass valve, J3-by-pass valve, LT-fluid level transmitter, the PT-pressure unit, the TE-RTD, TT-temperature transmitter, PY-pressure signal transmodulator, TY-temperature signal transmodulator, LV-liquid level pneumatic diaphragm control valve, PV-pressure pneumatic diaphragm control valve, TV-temperature pneumatic diaphragm control valve.Control process is such: the instrument (transmitter) by the scene detects, and signal enters into PLC, and the PLC output signal is to electropneumatic transducer, and electropneumatic transducer is controlled to topworks-diaphragm valve at output pneumatic signal.
The shortcoming that adopts pneumatic diaphragm control valve to carry out terminal control is: pneumatic diaphragm control valve must have instrument air (adopting pressurized air usually).For the user who does not have instrument air, need usually to be equipped with an air compressor and air cleaning unit, this has not only increased the one-piece construction of equipment, and has increased a source of trouble.
(3), summary of the invention:
In order to overcome the shortcoming of prior art, the present invention relates to the application of magnetic valve in device for producing hydrogen, adopt magnetic valve that liquid level is controlled, its advantage is that instrument air need not be provided, and the magnetic valve volume is less, is convenient to complexes and carries out Highgrade integration.
The present invention solves the technical scheme that its technical problem takes: on the hydrogen separator of water electrolysis hydrogen producing equipment and oxygen separator fluid level transmitter LT is housed, pressure unit PT, temperature transmitter TT, liquid level signal transmodulator LY, pressure signal transmodulator PY, temperature signal transmodulator TY, liquid level PLC, pressure P LC, temperature PLC, liquid level pneumatic diaphragm control valve LV, pressure pneumatic diaphragm control valve PV, temperature pneumatic diaphragm control valve TV, it is characterized in that: described liquid level pneumatic diaphragm control valve LV, pressure pneumatic diaphragm control valve PV, temperature pneumatic diaphragm control valve TV uses the liquid level magnetic valve respectively, pressure solenoid valve, the temperature magnetic valve is replaced, and has removed signal converter separately accordingly.
Adopt magnetic valve that liquid level, pressure and temperature are controlled, its advantage is that instrument air need not be provided, and the magnetic valve volume is less, is convenient to complexes and carries out Highgrade integration.Owing to reduced air compressor and air cleaning unit, cost has reduced.
(4), description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the prior art schematic diagram;
Fig. 2 is principle of the invention figure.
(5), embodiment
As shown in Figure 2, among the figure: 1-hydrogen separator, 2-oxygen separator, LV-1-master's liquid level magnetic valve, LV-2-assists the liquid level magnetic valve, PV-1-principal pressure magnetic valve, PV-2-assists pressure solenoid valve, TV-1-main temperature magnetic valve, TV-2-assists the temperature magnetic valve, the LT-fluid level transmitter, PT-pressure unit, TE-temperature sensor.
On hydrogen separator of water electrolysis hydrogen producing equipment (1) and the oxygen separator (2) fluid level transmitter LT and pressure unit PT are housed, temperature sensor TE is housed on the alkali lye cooling duct, after PLC control, carry out the control of liquid level, pressure and temperature by liquid level magnetic valve (LV-1, LV-2), pressure solenoid valve (PV-1, PV-2), temperature magnetic valve (TV-1, TV-2) respectively.Adopt two magnetic valves to control when adopting magnetic valve as topworks, main solenoid valve need be according to the circulation Lectotype and calculation of gas, and auxilliary magnetic valve plays auxiliary adjustment and safety is unloaded the effect of putting, and general circulation can be amplified on the basis of calculating a little.During normal regulating, regulated by main solenoid valve, only under improper situation, auxilliary magnetic valve just moves.Because the controlled variable of hydrogen producer is certain, if the circulation of magnetic valve is calculated accurately, the switching frequency of magnetic valve is very low.
