There is material but no gas in the digester Why

1. The biogas digester should be frequently fed and discharged.

The fermentation raw materials added to the biogas digester are fermented by biogas bacteria to produce biogas, and the nutrients in the raw materials will be gradually consumed or transformed. In order to keep the biogas bacteria have enough food and to produce gas properly, it is necessary to constantly replenish fresh raw materials. When feeding the biogas digester, the material should be discharged first, and then the feeding, so as to maintain the volume of the gas box.

If only feed is fed and not discharged for a long time, the volume of the gas box will be filled with fermentation broth and there will be no biogas available.

2. Stir the fermentation raw materials in the biogas digester frequently.

Only by making uniform contact between the fermentation raw materials and the biogas bacteria can the normal fermentation and gas production be ensured. Frequent stirring of the fermentation raw materials in the biogas digester has two advantages: first, it can make the fermentation raw materials and bacteria in the biogas digester evenly distributed, and the biogas bacteria can fully contact the fermentation raw materials, with good nutrition, rapid growth and reproduction, and improve gas production; Second, it can break the crust of the upper layer, so that the biogas produced by the middle and upper layers attached to the fermentation raw materials is aggregated from small bubbles into large bubbles and rises into the gas box.

3. Control the pH of the hair liquid.

If the fermentation raw material is too concentrated, the volatile acid will accumulate too much, which will lead to the inhibition of the growth of methanogens, resulting in too much miscellaneous gas and cannot be ignited and burned. To determine whether the fermentation broth is too acidic, you can use pH test paper to determine whether it is too acidic. The normal pH value of the feed solution is in between.

If the feed liquid is found to be too acidic, an appropriate amount of lime water (lime blocks cannot be used, otherwise it is easy to produce precipitate) or alkaline substances such as plant ash can be added from the feed port, and at the same time, a long manure spoon can be inserted into the feed port and stirred back and forth.

As the saying goes, "three points to build a pool, seven points to manage", in the daily use of the biogas digester, due to the different factors such as fermentation raw materials, fermentation concentration, gas consumption and stoves of each household, the majority of users need to carefully observe the operation of their own biogas digester, often check the pipeline, find problems and deal with them in time, and constantly summarize experience, in order to maximize the benefits of the biogas digester.

There are many reasons for this. First of all, the pool does not leak. Check not only for water leakage, but also for air leakage.

There is a supporting procedure for the inspection method, and the inspection is carried out according to the regulations. Second, the fermentation of raw materials is not reasonable. This includes whether or not there is a sterilized fermentation material.

If it's not sterilized, it depends on your fermentation ingredient ratio. Third, it depends on whether there is an abundance of inoculum. Vaccination is very important.

And the amount of inoculum should be about one-third of the total amount of raw materials.

If the above three points are fully met, your digester will definitely produce gas. We apologize for any inaccuracies.

Summary. Hello dear, it is a pleasure to serve you! For your inquiry, it is not recommended to feed biogas from the discharge port.

The discharge port and inlet of the biogas digester must be covered with protective covers to prevent people and animals from falling into the pool. It is strictly forbidden to open the cover at will. The scrapped biogas digester should be backfilled in time.

It is strictly forbidden to smoke or use an open flame around the digester. The fire test must be carried out on the stove, and it is strictly forbidden to test the fire in the gas digester air duct and input pipe. When the pressure gauge pressure is too high, pay attention to safe deflation.

It is strictly forbidden to deflate indoors in case of **. The feeding and discharging materials should be balanced and not too large. If the number of feeding is large, the switch should be turned on, and then slowly added, more material is discharged at one time, and the switch should be turned on when the pressure gauge drops to zero, so as to avoid excessive negative pressure and damage to the biogas digester.

The desulfurizer in the purifier is generally replaced once every six months, and the replaced desulfurizer can be dried in a cool place and then used 2-3 times.

Kiss, 1It is not allowed to feed in the pool. When the biogas digester starts feeding, it must be added from the skylight or feed port, and it is strictly forbidden for personnel to go down to the pool to feed.

2.It is not allowed to add a large amount of material and water at will. When the amount of water added to the material is relatively large, the gas opening switch should be turned on, and the same amount of material liquid should be produced first, and then slowly added, so as not to damage the swamp shengxiang positive gas pool.

It is not allowed to use biogas stoves during the normal feeding and discharging of the banquet, and it is strictly forbidden to approach the biogas digester with open flames. 3.It is not allowed to enter the pool without safety precautions.

Kiss, be sure to remember it.

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 the pure transportation of gas in swampy wetlands. It is often seen that bubbles come out of swamp pants dusty fields, sewage ditches or manure tanks, and if we strike a match, we can light it, which is a natural occurrence of biogas in nature.

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

Biogas 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.

How to solve the problem of gas non-combustion in the biogas digester?Don't come if you don't understand!

A lot of gas is produced in the biogas digester, which is not methane-containing biogas or the content is still very small, but non-combustible gases such as water vapor and carbon dioxide. If your biogas digester is re-fed material, 1. There is a problem with the raw materials that are invested, and the raw materials contain antibiotic jujube retardin, etc. 2. The raw materials are not acidified and directly enter the biogas digester, and there is too little inoculum in the biogas digester.

The inoculum is not active. It is still dormant. 3. The liquid acidification in the biogas digester is caused by too much one-time feeding and too high concentration.

If your biogas ignition does not catch fire, release the gas, generally 2-4 days, the gas smells of rotten eggs, it means that it is running normally, put it a few more times, and it will be fine. If there is no rotten egg smell, the digester is acidified or the raw material is defective.

It is possible that your biogas digester is a newly started pond and the methane content of the gas produced is not enough, so wait a few days to try to light the fire and release the gas every day.

When the biogas is first started, the gas produced is mainly carbon dioxide, but there is also residual air in the pond, which has a low methane content and usually cannot be ignited. When the pressure gauge water column rises to 30 40 cm, it can be deflated to test the fire.

Once or twice, (deflation is generally carried out on the stove, and must not be carried out at the mouth of the gas pipe), the biogas generated after it can be ignited and used.

There are many reasons for not producing gas, mainly the following situations:

1. There are too few methane species, or there is basically no vaccination;

2. Too much water, too little feces, and methanobacteria are in a state of starvation;

3. When the temperature is lower than 10 degrees, methanobacteria are basically inactive;

4. Too much feces, too little water, and methanobacteria are dead.

The appropriate ratio of fermentation raw materials is: water 4, feces 2, and bacteria 1

Methanobacteria prefer a neutral or slightly alkaline environment, and the temperature above 20 degrees Celsius is most active, so the pool temperature of the new pond should not be lower than 10 degrees. You can use the above points to find out why, or if you can't, you can only ask your local biogas professional to help you solve the problem.

The liquid temperature of the biogas digester is more than 20, no gas is produced, and the biogas slurry in the biogas digester is pumped out of two-thirds, and the material is newly fed, and the material must be stacked for fermentation first. Re-invest.

It can be analyzed according to the influencing factors of anaerobic fermentation, such as C-n ratio, temperature, pH, etc.
