Methane generating pit with humidity sensor for monitoring humidity change in pit

Abstract

The invention relates to a methane generating pit with a humidity sensor for monitoring humidity change in the pit, belonging to the technical field of networking application of new energy sources. Wind blows blades to quickly rotate to drive a wind power generator to generate a current, the current is input into a controller, an inverter and a current divider through conducting wires, and one path of current is divided into two parts of current in the current divider. One part of current is input into the humidity sensor installed in a methane storage room in the methane generating pit through a conducting wire, a sensing element of the humidity sensor senses the relative humidity of methane, a converting element converts the relative humidity value into electric signals suitable for transmission, the electric signals are input into a computer processer 1 for processing through a measuring circuit and are transmitted into the air through a transmitting antenna. The other part of current is input into the computer processor 1 and the transmitting antenna. After a receiving antenna receives the electric signals, the electric signals are input into a computer processor 2 for processing, and then, the relative humidity value of methane in the pit is displayed on a display screen of a displayer.

Description

technical field [0001] The invention relates to a biogas digester in which a humidity sensor is installed in the pond to monitor the humidity change in the pond, and belongs to the technical field of new energy Internet of Things application. Background technique [0002] People stir the mud at the bottom of the pond with wooden sticks, and find a series of bubbles rising to the surface of the water. The bubbles are collected into glass bottles by drainage method, and then biogas can be obtained. The main components in biogas are 55%-70% methane, 28%-45% carbon dioxide, 1.88% oxygen, 0.034% hydrogen sulfide, and a very small amount of oxygen and carbon monoxide, which often appear in natural swamps. Gas, so it is called biogas. It can also be known from this that the production of biogas is inseparable from water, and there must be a certain degree of humidity in the biogas. [0003] In the vast rural areas and cities, there are many organic matters that are decomposed by ...

AI Technical Summary

Problems solved by technology

[0004] The biogas slurry inside the biogas digester must maintain a suitable concentration of fermentation liquid to produce more biogas. The concentration range of the fermentation liquid is 2-30%. The concentration of the fermentation liquid is related to the relative humidity of the biogas in the biogas storage room. The biogas storage room The relative humidity of the biogas is also related to the gas production rate of the biogas pit. Since the biogas pit is tightly sealed, people cannot put a hygrometer into the biogas pit to measure the relative humidity of the biogas in the pond.
