Make dog shit biogas and other remains - Guide

[Christophe]

There's nothing rocket science about making biogas!
Making quality biogas is much more difficult.

The main technical concern in our latitude is maintaining the temperature (especially in winter).

I know all that, but I want to find a more professional and fairly small method.

on the other hand I can no longer find my password for the download, could you send me a PM?

Goods.

The method is the same! To "professionalize" it, it is "sufficient" to automate, therefore to add sensors, controls, actuators, heaters... in the places that are going well...

Yesterday dedeleco wrote a message https://www.econologie.com/forums/post218945.html#218945 on this other subject: https://www.econologie.com/forums/methaniseu ... t9583.html totally on topic with this one:

A simplistic methanizer that is not tiring: a cow or ox:

A cow produces up to 600 liters of methane per day: an impact equivalent to a car traveling 40 kilometers per day

Just plug into it, on the back of the cow, with a balloon, without piercing it and you will save the planet, by burning this methane.

Even, if you forget to empty the balloon, the cow will fly away!!!
Except spark, so boom!
Serious error:

95% of this greenhouse gas is evacuated through the mouth and nostrils, 5% through untimely flatulence!

Hard hard..

Biogas digester

Many Footsteps readers have been asking us for information about biogas digesters for several years. So far we have not been able to convey much useful information about small digesters. However, this model by Charlie Forst of ECHO is designed for a household with the manure of three or four cows or buffaloes, or six goats: it can produce enough cooking gas and light for a whole family.

The purpose of using a biogas digester is to enclose methane gas from animal manure to produce domestic gas for cooking or light. All kinds of models have been created, but the world is full of biogas digesters that do not work. The idea proposed here is simple and practical, but the digester requires special daily attention for it to work properly. After being used in the digester, manure can serve as an excellent fertilizer.

1 You need to get five big cans or drums (44 gallons or 80 liters of capacity). Plastic cans are the best, but if metal cans are the only ones available, a coat of paint on the inside will prevent hole formation. (Pour the paint into can A and roll it so that the paint covers the whole interior.) Two of the cans must be a little smaller to fit easily into larger ones (and move freely from top to bottom).



2 Container A: the digester, requires a tightly closing lid (it does not need to be removed). Attach a large bamboo or plastic pipe that goes all the way to the bottom of the digester with the side cut off so it can be used to mix the manure more easily. Then install a plastic pipe fitting just in the hole of the cover, with if possible a valve to regulate the flow of gas. Hermetically seal all connections with tar.

3 Return an empty plastic can and place it inside the can B. You do not need covers for these two cans because the water serves as a seal. The pipe containing the gas enters through the top of the can returned and attaches a double connector. The gas first enters the can B, but as it fills it enters the canister C which is built in exactly the same way as the can B. The methane for cooking and light flows can B by another plastic pipe. This pipe carries him to the kitchen. Use bricks or stones to put weight on cans B and C and to increase the pressure.

4 When you start the digester, only cow manure should be used for proper operating conditions. Goat or buffalo manure does not work! Once started, collect the fresh manure from the animals each day with a bucket. Remove approximately 2% of manure (manure and water mixture) from the digester daily. Let stand. Remove the liquid and mix it with fresh manure. You may need to add some water to get a smooth mix. Add it carefully into the digester by the big pipe and mix well. It is essential to thoroughly mix the contents of the digester once a day, otherwise a crust will form and the digester will not work. You can not miss a few days forgetting your biogas digester!

Charlie ties an old tin can to a stick and uses it to scoop out, mix or pour manure. To really mix the manure well in the digester, he adapts this tool and adds a simple valve to it. He cuts out the bottom of the box and secures it to one side with wire, and uses a larger wire loop to secure the other side. This allows him to bring up the manure from the bottom of the container and mix it well.

5 The manure used can then be used as fertilizer. But be careful, it is very powerful and risks burning the plants if you do not mix it with water or incorporate it into compost.

6 Methane is potentially dangerous; therefore do not smoke near the digester and place it at a safe distance from the kitchen.

Thank you, I keep thinking about my thing, I have the possibility of finding used resin or plastic silos, I'm also thinking of a slurry pit stirrer, and a gas boiler (vacuum or condensation).

for almost instantaneous use to heat up my stock of solar hot water (still project).
