Description

Device for culturing and enriching excellent methane strain

Technical Field

The utility model relates to a device of screening enrichment bacterial, especially one: a device for culturing and enriching good methane strains.

Background

At present, the popularization of the technology for preparing methane from carbon dioxide is directly restricted due to the fact that various methane strains in the methane strains are mixed and the breeding speed is slow. Therefore, the design of a device for separating the optimal methane strain and culturing and enriching the excellent methane strain is a technical problem to be solved at present.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: provides a device for culturing and enriching excellent methane strains.

The technical scheme of the technical problem solved by the utility model is that:

the device for culturing and enriching the excellent methane strain consists of a large anaerobic pool, a steam boiler, a discharging machine and a bag-filling sealing machine. Mixing the anaerobic digestion fermentation raw materials according to the carbon-nitrogen ratio, uniformly mixing, and filling into a large anaerobic tank, wherein the top of the large anaerobic tank is provided with a methane outlet. The steam outlet of the steam boiler is communicated with the steam inlet at the bottom of the large anaerobic tank, and the gas outlet of the carbon dioxide gas steel cylinder is communicated with the carbon dioxide gas inlet of the large anaerobic tank. The motor-pumped well is internally provided with a submersible pump, a water discharge port of the submersible pump is communicated with a water inlet of the large anaerobic tank, and an ultraviolet sterilizer and a methane bacteria inlet are respectively arranged on a pipeline between the water discharge port of the submersible pump and the large anaerobic tank. The bottom of the large anaerobic tank is provided with a discharge door, the discharge door is connected with a culvert, a gas outlet of a carbon dioxide gas steel cylinder is communicated with the culvert, a discharge machine is arranged in the culvert, the discharge machine is communicated with a bag sealing machine, and a discharge outlet of the bag sealing machine discharges products: bagging methane strain.

The method for culturing the enriched excellent methane strain and the specific operation thereof are as follows: fresh raw materials required by anaerobic digestion fermentation are filled into a large anaerobic tank. Fresh raw materials required for anaerobic digestion fermentation: firstly, fresh domestic garbage, fresh crop straws, fresh livestock and poultry excrement water and the like; and secondly, mixing fresh raw materials required by anaerobic digestion fermentation according to the requirement of carbon-nitrogen ratio, uniformly mixing, filling into a large anaerobic tank, and filling the anaerobic digestion fermentation raw materials. Secondly, high-temperature steam discharged by the steam boiler is injected into the bottom of the large anaerobic tank through the high-temperature-resistant air pump, the steam rises, and cold air is discharged from the methane discharge port, so that the temperature of anaerobic digestion fermentation raw materials in the large anaerobic tank reaches 100 ℃, all microorganisms and worm eggs in the large anaerobic tank are killed, and the phenomenon that sundry bacteria exist and the purity of excellent methane bacteria is influenced is prevented. And thirdly, opening a carbon dioxide gas bottle valve, injecting carbon dioxide gas into the bottom of the large anaerobic tank, and completely replacing oxygen in the large anaerobic tank by the carbon dioxide gas because the specific gravity of the carbon dioxide gas is greater than that of the oxygen, and discharging air from a methane discharge port of the large anaerobic tank to prevent the methane bacteria from being damaged by the oxygen. Pumping underground water from the well by a submersible pump, injecting the underground water into a large anaerobic tank, installing an ultraviolet sterilizer on a water conveying pipeline, emitting ultraviolet rays to kill bacterial ova in the underground water, injecting the optimal methanobacteria separated from more than 80 methanobacteria into the water conveying pipeline, slowly raising water in the large anaerobic tank, and stopping water injection after the water is full. At the moment, the optimal methane bacteria are uniformly distributed in the anaerobic digestion fermentation raw material along with water, the anaerobic digestion fermentation raw material in the large anaerobic pool starts to ferment, and the anaerobic digestion fermentation raw material is biogas residue after fermentation, namely the optimal methane bacteria. The bottom of the large anaerobic tank is provided with a discharge door, a culvert is arranged outside the discharge door, the culvert inclines upwards at an angle of 45 degrees, and a discharge machine and a bag filling sealing machine are arranged in the culvert. Firstly, a carbon dioxide gas bottle valve is opened, carbon dioxide gas is injected into the culvert, and the oxygen is forced to be discharged from the culvert because the specific gravity of the carbon dioxide gas is greater than that of the oxygen, so that the methane bacteria are prevented from being damaged by the oxygen. After the carbon dioxide gas is filled, the discharge door at the bottom of the large anaerobic tank is opened, the discharge machine and the bag-filling sealing machine start to work, and the bag-filling sealing machine outputs products: the process of bagging methane strains is automated.

Compared with the prior art, the utility model discloses can cultivate the methane bacterial strain that enrichment is superior with the best methane bacterial that separates out, guarantee the purity of best methane bacterial strain, make it reach good oxygen fungus reproduction speed to promote carbon dioxide and prepare methane technical development, benefit the mankind.
