Embodiment 1

[0042] Such as figure 1 and figure 2 Shown, a kind of control device of oxyhydrogen generator, comprises:

[0043] PLC controller 1,

[0044] Electrolyzer liquid level monitoring system 3, the input end of described electrolyzer liquid level monitoring system 3 is used for being electrically connected with hydrogen-oxygen generator, and the output end of electrolyzer liquid level monitoring system 3 is electrically connected with PLC controller 1, is used for The liquid level information of the electrolytic cell of the hydrogen-oxygen generator is sent to the PLC controller 1;

[0045]The electrolyzer liquid level monitoring system 3 includes a differential pressure transmitter and a float level gauge installed in the electrolytic tank of the hydrogen-oxygen generator, the differential pressure transmitter is electrically connected to the PLC controller 1, and the PLC controller 1 is also It is electrically connected to the water pump of the hydrogen-oxygen generator, the ...

Embodiment 2

[0076] Such as Figure 1 to Figure 3 Shown, a kind of automatic regulation method of hydrogen-oxygen generator electric current, comprises the following steps:

[0077] The first step is to set parameters, and set the current setting value, step size and sensitivity for the PLC controller 1 through the touch screen 8, the step size is a fixed current value, and the sensitivity is an acceptable error range.

[0078] The second step is the first judgment, read the actual current value in the hydrogen-oxygen generator as feedback, if the feedback value is less than the current setting value, add a step size on the basis of the actual current value, that is, increase the actual current value If the current value is one step larger, repeat the second step after adding one step until the feedback value is greater than or equal to the current setting value; if the feedback value is greater than or equal to the setting value, make a second judgment;

[0079] The third step is the secon...

Abstract

The invention discloses a control device for a hydrogen-oxygen generator. The control device for the hydrogen-oxygen generator comprises a PLC, an electrolytic tank liquid level monitoring system, a gas accommodating chamber pressure monitoring system, a current regulating system, an alarm system, a remote monitoring system, a touch screen, a rectifying power controller and a rectifying inverter unit. A current value can be automatically set, a double monitoring is provided through a liquid level and air pressure, the hydrogen-oxygen generator cannot work normally or an accident is brought dueto the fault of the PLC is avoided, safety is high, and high efficiency is achieved.

Description

technical field [0001] The invention belongs to the field of hydrogen and oxygen generators, and in particular relates to a control device for hydrogen and oxygen generators. Background technique [0002] The hydrogen-oxygen generator generates hydrogen-oxygen mixture through electrolysis of water as flame cutting, which is a common way for continuous casting cutting in steel mills. With the continuous development of my country's industrialization, the requirements for informatization and automation development are gradually increasing, especially in the steel mill industry. However, the automation level of most hydrogen and oxygen generators on the market is generally not high. The existing hydrogen and oxygen generator equipment uses PLC, touch screen, differential pressure transmitter, PT100, digital display pressure gauge and other control equipment to monitor the temperature of the hydrogen and oxygen generator, the liquid level of the electrolytic tank and the chamber...
