Embodiment

[0023] Such as figure 1 An energy system with the help of sulfur cycle shown, including hydrolysis tank 1, anaerobic tank 2, water outlet tank 3, aerobic aeration tank 4, hydrogen sulfide collection cabinet 5, anaerobic oxygen collection cabinet 6, closed combustion system 7. Gas scrubber 8, sulfur-containing water collection tank 9, tail gas treatment system 10, tailings treatment system 11 and tail water treatment system 12.

[0024] refer to figure 1 , the operating method of the present embodiment includes the following steps:

[0025] Step 1: preparation; put the sulfate into the hydrolysis tank 1;

[0026] Step 2: feeding; adding organic waste to the hydrolysis tank 1;

[0027] Step 3: hydrolysis; carry out hydrolysis reaction in the hydrolysis tank 1, and import the gas generated in the hydrolysis tank 1 into the anaerobic oxygen collection cabinet 6; the main function of the hydrolysis tank 1 is to hydrolyze the organic waste into small molecules that are easy for m...

Abstract

The invention discloses an energy system with the help of sulfur cycle. For those conditions that are not conducive to the growth of methanogens, the sulfur cycle can be used, that is, sulfate / sulfite is reduced to sulfide by sulfate-reducing bacteria, and the After the sulfide is acidified into hydrogen sulfide, it is closed and burned to obtain energy. Sulfur dioxide generated after hydrogen sulfide combustion is washed with water to generate sulfurous acid, which enters the anaerobic system, and then is reduced by sulfate-reducing bacteria to form a cycle and continuously obtain energy.

Description

technical field [0001] The invention relates to an energy system, in particular to an energy system utilizing sulfur cycle. Background technique [0002] The most familiar energy system is the carbon cycle system: low-priced carbon is burned to generate high-priced carbon and release energy; high-priced carbon (usually CO 2 ) is reduced to low-priced carbon by plants, and then burned to form a cycle. [0003] Sulfur element also has this cycle: low-valent sulfur (S 2- , S 0 etc., represented by sulfide and elemental sulfur) burn to generate high-valent sulfur (S 4+ , S 6+ etc., represented by sulfur dioxide and sulfate) and release energy; high-valent sulfur is reduced to low-valent sulfur by sulfate-reducing bacteria, and then burned to form a cycle. [0004] However, many sulfur compounds are harmful to humans, so no one has studied the practical application of this cycle. [0005] If the sulfur cycle is placed in a closed system so that various sulfur compounds gene...
