Doomsday Bunker Upgrade Chapter 75: Algae cycle oxygen generation for power generation

　　To solve the problem of electricity consumption, either the biomass produced by the oxygen generator created by Chen Xin can be used for biogas power generation to meet its own consumption, or Chen Xin will continue to upgrade the current shelter’s power system. The hope is to upgrade it to a more self-sustaining power system, such as a nuclear reactor that can operate for decades.

The first option is naturally impossible because of conservation of energy.

If the biomass produced by the oxygen generator can be used for biogas power generation to meet the system's own consumption, doesn't it mean that it is a perpetual motion machine?

So the solution to the problem is to continue to upgrade the system, and to upgrade to energy saving and replacement.

　　 It’s just that Chen Xin has checked his own generator and power system. In the system upgrade options, there are only two upgrade options to improve the efficiency of the generator and the energy saving rate of the entire power system. I want to upgrade it to other types Generators are not yet possible.

　　 But this is not absolute. Chen Xin thinks that when he upgraded his protective clothing before, he provided a tactical poncho to make the protective clothing more of the function of a raincoat and surface tactical camouflage. He felt that if he could provide other power generation methods, It can also be integrated into the power system.

　　 "If I integrate biogas power generation into the power system, with gasoline generators as the main power and biogas power generation as an auxiliary, two methods of power supply at the same time..." When I thought of integrating other power generation methods into the power system, Chen Xin quickly took it. Calculate with pen and paper. ,

"The current consumption of the greenhouse requires the generator to consume 20 liters of gasoline per day to maintain, and the consumption remains unchanged..."

　　"The planting greenhouse can meet my own oxygen consumption when there is light, and there is a surplus output... But considering the overflow of the ventilation system and the oxygen consumption after turning off the lights..."

　　"Under the condition that the light time remains unchanged for 12 hours, the oxygen produced in the planting greenhouse can maintain my consumption for 16 hours without considering the presence of external oxygen..."

　　"Extending the light time to increase the oxygen output can provide the oxygen I need for 24 hours, but at least five hours of light per day will be added, and the gasoline consumption will increase from 20 liters/day to 30 liters/day..."

　　"If the algae circulating oxygen generator is constructed, the electric power consumption is less than that of maintaining the long-term sunlight in the planting greenhouse. With the supplement of electricity brought by the biogas power generation, only 5 liters of gasoline consumption needs to be increased every day..."

List the various data for calculation, and Chen Xin can easily calculate the result.

　　 Looking at the results he calculated, Chen Xin stroked his chin. It was obvious that the construction of an algae circulating oxygen concentrator he told Mo Qingyan was the least consuming solution at present.

　　 And when Chen Xin built such an oxygen generator, he could completely upgrade the oxygen generator through the system to improve its oxygen production efficiency, biomass output, biogas reaction efficiency... or even biogas Power generation is transformed into biomass fuel cells or the produced biomass is converted into edible algae.

　　 Thinking of this, Chen Xin was sincerely grateful that he had picked up this system when he entered the refuge, instead of turning a blind eye to it as an ordinary meteorite.

—————————————————————

Since he decided to build an oxygen generator, Chen Xin obviously had to take stock of the resources he had.

After all, this is not like upgrading an existing item, he can directly upgrade it with the help of the system's survival points.

This is also the biggest shortcoming of this system, it cannot create something out of thin air, it can only be upgraded based on what is already there.

No matter how simple and primitive the items used as the basis for upgrading are, as long as there is a material basis, the system can continuously improve them.

But without this foundation, nothing will be discussed.

　　 So even if Chen Xin built a sink with wooden boards to grow algae in the water, and then insisted that it was an oxygen generator, he had to build the sink first.

Fortunately, the materials on Chen's novice are not lacking. He doesn't need to build a sink with wooden boards.

To build an algae circulating oxygen generator, the first thing you need is not a water tank, but a foundation for algae growth, that is, a biological facade.

This is not complicated. If you are not so particular, the screen windows used at home can also be used.

Let the algae attach to it, then provide water, carbon dioxide and light, and soon the algae will begin to grow and reproduce, and photosynthesize to release oxygen.

　　 As for the sink, this is actually not necessary, because a water pipe can be made to hang on the attachment of the algae, and the algae can be kept moist through the pipe, without the need to completely soak it in the water.

If the conditions are better, it can provide a better base for algae to attach to.

　　The German technology is to manufacture hollow glass plates, connect supply lines and discharge lines to these hollow glass plates, and then pour culture medium into the hollow glass plates to cultivate algae.

　　 At the lower end of a single hollow glass plate, carbon dioxide as a nutrient is injected into the culture medium through the supply line to produce bubbles~IndoMTL.com~The vortex formed during the rise of bubbles will stimulate the algae in the culture medium to absorb carbon dioxide and light, and perform Photosynthesis, continuous growth and reproduction.

When the algae grow and reproduce to a certain extent, the algae in these hollow glass panels will be recycled and the biomass will be harvested.

　　According to the experimental data given by the Germans at that time, such a square meter of hollow glass plate can produce 900 kilograms of biomass a year, and about 10 liters of methane can be produced per day. It can produce more than 600 cubic meters of methane per year.

These methanes can be used for power generation to generate 4500kW/h of electricity and 6000kW/h of thermal energy, which can be said to be quite clean and efficient.

Of course, the Germans use fuel cells instead of simply burning methane to release heat to generate electricity, which is much more efficient.

　　For Chen Xin's current supplies, he can only use screens or other things that are easy to attach to as a basis for attachment, and then pour water on it and provide light to allow it to grow algae.

In simple terms, it is to build a simple device first, let it run first, and then consider upgrading it to improve operating efficiency and expand production capacity.

All you need to make a simple device is a sink, a miniature vacuum pump, a few PVC pipes, and an attached façade.

　　 These things Chen Xin looked through his material storage room, and quickly found out what they needed, although they might not be so compatible and needed some modification.

　　 is a little different in size, causing the pipes and vacuum pumps to fail to connect, the sink is simply a plastic box, and the attached facade is also the screen window removed from the window of the container house...

Looking at these things, Chen Xin felt that maybe he should make himself a workbench first.
