Description

TECHNICAL FIELD

[0001] The utility model relates to electrolytic hydrogen production technical field especially relates to a device for electrolytic hydrogen production of industrial wastewater. BACKGROUND

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to the wastewater and waste liquid generated in the industrial production process, containing industrial production materials, intermediate products, by-products and pollutants generated in the production process. Industrial wastewater can be made into hydrogen by electrolytic hydrogen production device, thereby obtaining more energy.

[0003] For the existing patent number CN116590727A, a kind of electrolytic device for hydrogen production of industrial wastewater is disclosed, including electrolytic cell, bifurcated pipe, sealing ring and sealing cover etc.;Electrolytic cell is equipped with feed pipe;Electrolytic cell is communicated with two bifurcated pipes;All bifurcated pipes are equipped with a sealing ring for preventing gas transfer to the outside at electrolytic cell connection;All bifurcated pipes are equipped with a sealing cover at electrolytic cell connection, and sealing cover is attached to electrolytic cell, and sealing cover is wrapped at bifurcated pipe and electrolytic cell connection. The hollow column is used in cooperation with the second collecting frame in the present application, to more efficiently collect the flocculation in the stirring barrel, avoid the influence of flocculation on the reaction of industrial wastewater and medicine. The deficiency of the device is that the water injection situation in electrolytic cell cannot be controlled in real time, when water level rises to a certain height, water surface will cover the two gas outlets of hydrogen gas pipeline and oxygen pipeline, so that hydrogen and oxygen cannot be discharged from the two hydrogen gas pipelines and oxygen pipelines, and there is also the possibility of water being guided out from the pipeline under the action of pressure difference, thereby affecting the collection of gas.

[0004] Therefore, in view of the above-mentioned problem that the water level cannot be monitored, resulting in the inability to normally collect gas, an industrial wastewater electrolytic hydrogen production device can be designed. The contact between the annular copper sheet and the two groups of circular copper sheets causes the alarm circuit to close, thereby causing the alarm to emit an alarm signal, thereby stopping water injection, effectively preventing the wastewater from covering the gas discharge port, and facilitating the smooth progress of hydrogen production. UTILITY MODEL CONTENT

[0005] In order to overcome the problem that the existing water level cannot be monitored, resulting in the inability to normally collect gas.

[0006] The technical solution of this utility model is as follows: a device for producing hydrogen by electrolysis of industrial wastewater, including an electrolysis tank, a lithium battery box fixedly connected to the side of the electrolysis tank, an alarm set on one side of the lithium battery box, the lithium battery box and the alarm being electrically connected, the lithium battery box providing power to the alarm, an alarm light installed on the outside of the alarm, a speaker set below the alarm light, two sets of copper wires fixedly connected inside the alarm, one set of copper wires connected to the positive terminal of the alarm, and one set of copper wires connected to the negative terminal of the alarm, one end of the copper wires being inserted into the inside of a copper tube, the copper tube being fixedly connected to the top of the electrolysis tank, a threaded hole being opened on the side wall of the part of the copper tube exposed above the electrolysis tank, a fastening bolt being connected inside the threaded hole, a circular copper sheet being welded to the bottom of the copper tube, the circular copper sheet being inside the top of the electrolysis tank, a solid insulating column being fixedly connected inside the electrolysis tank, a float being set on the outside of the solid insulating column, and an annular copper sheet being fixedly connected to the top of the float.

[0007] Preferably, the annular copper plate on the float rises to the bottom of the two sets of circular copper plates and comes into contact with them. At this point, the annular copper plate connects the two sets of circular copper plates, forming a closed circuit. This connects the two sets of copper pipes fixedly connected above the two sets of circular copper plates to the two sets of copper wires, thus forming a closed circuit between the positive and negative terminals of the alarm connected to the two sets of copper wires. This causes the alarm to activate, emitting a red light and a buzzer sound, prompting the operator to stop adding water to the electrolysis tank. The external controller controls the solenoid valve to stop the water injection pipe, preventing the water level from rising to a certain height and blocking the outlet ports of the hydrogen and oxygen collection pipes, thus preventing the collection of hydrogen and oxygen and potentially causing wastewater to be discharged. This provides the device with a liquid level alarm function, further enhancing the device's safety.

[0008] Preferably, a water injection pipe is fixedly connected to the side of the electrolysis tank, and a solenoid valve is installed inside the water injection pipe.

[0009] Preferably, when the alarm is activated, the alarm light turns red and the speaker emits a buzzing sound.

[0010] Preferably, a hydrogen-producing electrolysis column is installed inside the electrolysis tank, and the hydrogen-producing electrolysis column is the cathode.

[0011] Preferably, a diaphragm is fixedly connected to the middle of the inner side of the electrolysis tank.

[0012] Preferably, an oxygen-generating electrolysis column is installed on the side of the electrolysis tank away from the hydrogen-generating electrolysis column, and the oxygen-generating electrolysis column is the anode.

[0013] As preferred, the electrolytic tank is fixedly connected with a hydrogen collecting pipe, the hydrogen collecting pipe is connected with an external hydrogen collector, and an oxygen collecting pipe is arranged on one side of the hydrogen collecting pipe and fixedly connected with the top of the electrolytic tank, and the oxygen collecting pipe is connected with an external oxygen collector.

[0014] The utility model discloses the beneficial effects of:

[0015] The device for electrolyzing industrial wastewater to produce hydrogen, when the water level rises to a certain degree, the annular copper sheet on the floating block rises to the bottom of the two groups of circular copper sheets and contacts the two groups of circular copper sheets, at this time, the annular copper sheet connects the two groups of circular copper sheets to form a closed circuit, so that the two groups of copper pipes fixedly connected above the two groups of circular copper sheets are connected with the two groups of copper wires, thereby forming a closed circuit between the positive and negative electrodes of the alarm connected with the two groups of copper wires, so that the alarm starts to work, the alarm light emits red light, and the loudspeaker emits a buzzing sound, prompting the staff to stop adding water to the electrolytic tank, and the controller controls the electromagnetic valve to stop the water injection pipe from adding water, so that the water surface does not block the gas outlet ports of the hydrogen collecting pipe and the oxygen collecting pipe when the water level rises to a certain height, so that hydrogen and oxygen cannot be collected, and the wastewater may also be discharged, thereby realizing the function of liquid level alarm of the device and further improving the safety of the device.
