The principle of biogas fermentation tank:

The liquefaction stage is mainly the action of fermenting bacteria, including cellulolytic bacteria and protein hydrolysing bacteria. The acid producing stage is mainly the action of acetic acid bacteria. The methanogenic stage is mainly methane bacteria, which degrade the products produced in the acid production stage into methane and CO2. At the same time, the hydrogen produced by the acid production stage is used to reduce CO2 to methane.

Biogas fermenters are mainly used to meet the living conditions of microorganisms, so that they can live in a suitable environment to achieve the purpose of high fermentation and high gas production.

Zhejiang Rui'an biogas fermentation tank use method and performance introduction

Liquefaction stage of biogas fermentation tank and anaerobic tank process:

It is not only crop straw and animal manure, but also includes various types of organic wastes. Most of them exist in the state of macromolecular carbohydrates, usually starch and fiber. This macromolecular state is not easily absorbed by the microorganisms, and is liquefied as long as the extracellular enzymes branched out by the microorganisms are effectively enzymatically digested to realize the process in which the small molecule compounds enter the microorganisms to produce a chemical reaction.

Zhejiang Ruian Biogas Fermentation Tank Impact:

The influencing factors of anaerobic fermentation are: raw material ratio, the ratio of carbon to nitrogen in anaerobic fermentation is 20-30, when the carbon-nitrogen ratio is 35, the yield is obviously decreased; the temperature is 35-40 °C; PH value For methane bacteria, it is absolutely necessary to maintain a weak environment. Its pH range is 6.8-7.5, the pH value is low, it increases CO2, a large amount of water-soluble organic matter and H2S are produced, and the increase of sulfide content inhibits methanogens. For the growth, the pH can be adjusted by adding lime, but the method of adjusting the pH is to adjust the carbon to nitrogen ratio of the raw material, because the degree of neutralization of the acid in the substrate is mainly ammonia nitrogen, and the higher the nitrogen content of the substrate, the greater the degree. When VFA (volatile fatty acid) > 3000, the reaction stops.

The outstanding difference between biogas fermenters and other industrial equipment is that fermenters have very high requirements for pure cultures, which are almost very demanding. Therefore, the rigor of biogas fermentation tanks and the high reliability of operation are prominent features of the fermentation industry. In addition, it is also indispensable to strengthen the cleaning of the fermenter. The washing of the fermenter is in place, which is of great significance for the guarantee of product quality.

Biogas fermentation tank The fermentation equipment can be used to treat organic waste such as pig manure, chicken manure, cow dung, sheep manure, mushroom residue, Chinese medicine residue, crop straw, etc., and the harmless treatment process can be completed in 10 hours, occupying less land. (The fermentation machine only covers 10-30 square meters), no pollution (closed fermentation), completely killing the eggs (can be adjusted to 80-100 ° C high temperature), is the majority of aquaculture enterprises, recycling agriculture, ecological agriculture to achieve waste Zui good choice for resource utilization. In addition, according to customer needs, 5-50m3 different capacity, different forms (horizontal, vertical) fermenters can be customized.

The structural characteristics of the organic fertilizer fermentation equipment are: cylindrical container, ribbon stirring blade and transmission component; the cylinder structure ensures small resistance movement of the mixed material (powder, semi-fluid) in the cylinder. The positive and negative rotating screws are mounted on the same horizontal axis to form a low-dynamic and high-efficiency mixed environment. The ribbon-shaped blades are generally made of two or three layers, and the outer spiral gathers the materials from both sides to the center, and the inner spiral will The material is transported from the center to the sides, allowing the material to form more eddy currents in the flow. Speed ​​up the mixing and increase the mixing uniformity.

Biogas fermentation tank maintenance

If the intake pipe and the outlet pipe joint leak, when the screwing joint does not solve the problem, the filler should be added or replaced.

Pressure gauges and safety valves should be inspected regularly and replaced or repaired in case of failure.

When cleaning the fermenter, please use a soft brush to scrub, do not use a hard scraper to avoid damage to the fermenter surface.

The supporting instrument should be calibrated once a year to ensure normal use.

Electrical equipment such as electrical appliances, instruments, sensors, etc. are strictly prohibited from directly contacting water and steam to prevent moisture.

When the equipment is stopped, it should be cleaned in time to drain the remaining water in the fermenter and each pipe; loosen the fermenter lid and hand hole screws to prevent permanent deformation of the seal.

Carbon steel equipment such as operating platforms and constant temperature water tanks should be painted regularly (once a year) to prevent corrosion.

Always check the oil level of the gear unit. If the oil is not enough, it needs to be increased in time.

Production process of organic fertilizer rapid closed high temperature fermentation system,

Firstly, various pretreated biological wastes such as livestock manure and crop straw are added to the biogas fermentation tank according to the carbon-nitrogen ratio, carbon scale ratio, carbon-to-potassium ratio, pH value, moisture and formula, and the moisture is controlled at about 60%;

Part II: Add special high-temperature fermentation strains developed by our company;

The third step is to start the power supply heating, start the stirring system, and start the oxygenation system to promote the full contact of the organic raw materials with the air to avoid odor generated by anaerobic action.

The fourth step: using the high temperature of 80 ° C -100 ° C in the biogas fermentation tank to rapidly change the environment for microbial survival and reproduction, and improve the fermentation speed of organic raw materials. In this process, high temperature can quickly eliminate harmful pests and eggs in organic waste, and the high temperature bacteria we add will not be --- at this time, the high temperature bacteria we added are active and excited in high temperature and high humidity environment, sheep manure fermentation The tank can quickly decompose organic matter to achieve the purpose of quickly generating organic fertilizer.
