How to quickly and easily produce biogas residue from the biogas digester

It is convenient and fast for the biogas digester to produce biogas residue, with the biogas digester pumper, the biogas slag pumping truck is convenient, fast and safe.

1. General swamp pond cleaning (refueling from the top of the swamp):

1. Consider implementing a large change of materials in autumn throughout the year.

2. More than 10 bottom corner sludge or 10-30 fermentation broth should be left as inoculum during the large refeeding.

3. After slag removal, the raw materials prepared in advance can be put into the biogas digester, and the pond can be sealed immediately and re-activated.

4. Special attention should be paid to safe operation during large refueling to prevent suffocation accidents caused by hydrogen sulfide. Specifically, when cleaning the slag, the top cover of the fermentation tank is opened to fully aerate, and before the personnel enter the biogas tank, small animals such as chickens and ducks should be put into the tank, and if there is no impact on the life of small animals, they can enter the pool to remove the slag.

At the same time, it is necessary to pay attention to safety in the process of cleaning the slag, and hang a chicken in the pool while cleaning, so that it is safer.

2. Biogas digester Feeder A kind of biogas digester feeder has a circular cylinder, the upper side of the cylinder has a liquid outlet, the lower end of the cylinder is connected with a one-way opening bottom valve, the upper mouth of the cylinder is equipped with an upper cover, the upper part of the upper cover has a protruding ring, a sealing ring is installed in the annular cavity belt between the inner circle of the protruding ring and the outer periphery of the tie rod, and the upper part of the protruding ring is connected with a gland by threading. A one-way piston is installed in the cylinder, and the piston is connected to one end of the pull rod, and the other end of the pull rod stretches out outside the upper mouth of the cylinder through the center hole of the upper cover and is connected with a handle. The pump is installed in the biogas digester to solve the problem of difficult discharge of the biogas digester, avoid the crusting of the upper layer of the biogas digester, and improve the gas production per unit time.

3. Biogas slag pumping truck The utility model discloses a kind of biogas slag pumping truck, which is mainly composed of a frame, a diesel engine, an air pump, a transport tank, etc.; The main point of the utility model is that: the upper part of the transport tank is respectively provided with an air extraction pipe, a feed pipe, and a discharge valve is arranged below its rear end face. Because the utility model discloses a above-mentioned technical scheme, can reduce the cost by nearly half, and greatly improved the removal rate of biogas residue, biogas slurry, has:

Convenient, fast, safe and hygienic.

The annual biogas residue of 10 cubic meters of household biogas digester is 20-40 kilograms, and the problem can be solved by manual slag pump, without the need to use any machinery such as electric pumps. The slurry pump cannot pump out all the digestate in the pond at one time. What sewage pumps, single-phase sludge pumps, etc. in the world are unusable pumps, and they will be burned out as soon as the motor is used.

If you don't believe me, you can give it a try. A special biogas slurry pump is required. The biogas slurry pump cannot completely pump the digestate residue.

The digestate is at the bottom of the digester. Rod-shaped, short and stiff.

You can buy a two-phase sewage pump, and there are stores that sell pumps in the county.

Hello, the slag removal of the biogas digester can be combined with the needs of planting fertilizer and the slack season, generally every 3 months, about a year. Usually Xiaoqing takes out about 100 metric pounds of sediment; Daqing took out about 1,000 kilograms of sediment, and even completely refueled. Under the premise of normal production of biogas, within a certain period of time, it is necessary to hold the same amount of fermentation raw materials, domestic sewage and the same amount of extracted biogas slurry and biogas residue, which can be adjusted by adding an appropriate amount of plant ash sooner or later, or adding an appropriate amount of clarified lime water and mixing it with the fermentation broth.

Human, livestock and poultry manure and crushed crop straw are better used after decaying-yard finches.

Summary. The slag removal of the biogas digester can be carried out in combination with the needs of planting fertilizer and the agricultural slack season, generally every 3 months, and about one year for a large cleaning. Usually Xiaoqing takes out about 100 kg of sediment; Daqing took out about 1,000 kilograms of sediment, and even completely refueled.

Under the premise of normal production of biogas, within a certain period of time, it is necessary to add the same amount of fermentation raw materials, domestic sewage and the same amount of biogas slurry and biogas residue, and how to turn the slag in the biogas digester into water.

There is no need to shovel it, because although the bees have run away, there may be other bees coming, and if they are shoveled, they may not come. Because the bee trap nest beeswax is boiled by the old nest spleen, if you don't eradicate the desensitization, it may attract bees, and you don't need to rebuild the spleen.

The slag removal of the biogas digester can be carried out in combination with the needs of planting fertilizer and the agricultural slack season, generally every 3 months, and the sail is cleaned and transported for about a year. Usually Xiaoqing takes out about 100 kg of sediment; Daqing took out about 1,000 kilograms of sediment, and even completely refueled. Under the premise of normal production of biogas, within a certain period of time, it is necessary to add fermentation raw materials, domestic sewage and the same amount of biogas slurry and biogas residue to be pumped out of the beam, and an appropriate amount of plant ash can be added, or an appropriate amount of lime water and clarified lime water and fermentation broth are mixed evenly to adjust.

Biogas residue is not easy to remove.

How can you turn the dregs into water and pump them out.

That can only be extracted first, and a part of it can be dissolved with sodium hydrochloride solution with sodium hydrochloride.

Or the Blue Star.

Determine the height of plus or minus zero, and determine it according to the design drawing; When a new pool starts, apply warm water start, etc.

The height of plus or minus zero should be determined. The depth of the pit is determined according to the design drawing, that is, the top of the digester is kept on a level plane with the discharge port, and is 10 cm above the floor of the pig house. In order to facilitate the placement of the pool mold or the use of brick mold to pour the pool body and reduce the loss of materials, the pool pit should be round and vertical up and down.

For areas with good soil quality, the pit wall can be dug straight, and the soil can be excavated from the middle to the surrounding area.

The new pond is preferably started with pure cow and horse manure. When a new pool starts, warm water is applied to start. The water temperature is 30 -50, and it is forbidden to use cold water to start and prolong the starting time.

After feeding, seal the movable cover as required, and pay special attention to sealing the skylight to prevent air leakage. The gas produced at the initial stage of start-up is exhaust gas, which cannot be burned, and should be discharged for 7 days for more than 30 minutes a day.

It is a combustible gas produced by organic substances in an anaerobic environment, under certain temperature, humidity and pH conditions, through microbial fermentation. Because this gas was first found in swamps, lakes, ponds, people call it biogas.

Biogas, as the name suggests, is a gas found in swampy wetlands. It is not uncommon to see bubbles coming out of swamps, sewers or manure tanks, and if we strike a match, we can ignite it, which is a naturally occurring biogas in nature.

Biogas contains a variety of gas components, the main component being methane. The process by which biogas bacteria decompose organic matter and produce biogas is called biogas fermentation.

Biogas silver is a colorless, odorous, toxic and odorous gas, and its main component methane is a colorless, tasteless, odorless and non-toxic gas at room temperature.
