Problems solved by technology

When microbial fuel cells are connected in series, the single cells will show negative voltage or reverse polarization, which is called voltage reversal. The voltage reversal of the single MFC will cause the total voltage of the series loop to be almost zero voltage or negative voltage. The total voltage of the series cannot To achieve the purpose of increasing the voltage

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The invention provides a control method for automatically detecting the voltage reversal battery of the MFCs battery pack, and detects each single MFC connected in series on the circuit. When the polarity of the single MFC is normal, the single MFC is connected in series as a power supply to the circuit ; When the polarity of the single MFC is reversed, the two poles of the single MFC are shorted on the loop, and the single MFC is not connected to the loop.

[0021] The detection of the single MFC is as follows: compare the positive and negative poles of the single MFC through a comparator. When the polarity of the single MFC is normal, the comparator controls the two poles of the single MFC to open the circuit, and the single MFC is used as the power supply. Connected to the loop in series; when the polarity of the single MFC is revers...

Abstract

The invention relates to a control circuit and a control method for automatically detecting a battery with inverted voltage in an MFCs battery pack. The control circuit and method for automatically detecting the battery with inverted voltage in the MFCs battery pack can effectively disconnect the battery with inverted voltage from a total series circuit, and reconnect the other batteries in the series circuit, so as to increase the total voltage of the circuit. When new nutrients are added to an individual MFC with inverted voltage, the battery with reversed voltage has voltage increased to produce positive voltage again. The detection gate circuit reconnect the disconnected battery to the total series circuit in cycles, so as to improve the total voltage of the MFCs series battery pack. The control circuit and method not only can effectively reject the battery with inverted voltage in the series circuit, and improve the sewage treatment capability of the battery with inverted voltage, and has great value to the research on microbiological fuel cell as energy.

Description

technical field [0001] The invention relates to circuit detection and switching technology, more specifically, to a control circuit for automatically detecting voltage reversal batteries of MFCs battery packs, and a control method for automatically detecting voltage reversal batteries of MFCs battery packs. Background technique [0002] In recent years, the population has continued to grow. It is estimated that the global population will exceed 9.4 billion in 2050. The energy crisis that comes with population growth has gradually become prominent. Over the past century, fossil fuels such as oil have been the main source of energy for mankind, however, oil is expected to be depleted in the next 100 years or more. Therefore, it is particularly important to look for clean new energy and carry out energy structure reform. To this end, researchers have developed various clean energy sources such as solar energy, geothermal energy, and wind energy. Wastewater also contains energ...
