What is the reason why the pressure of the biogas digester is not purchased

There are many types of biogas digesters. If it is a normal traditional biogas digester, after the biogas is generated, the biogas in the gas storage room pushes the liquid level in the fermentation tank to drop, and the liquid level of the hydrostatic auxiliary pond rises (or overflows), and the water level difference between the fermentation pond and the hydrostatic auxiliary pond forms the biogas pressure. Under the premise that the seal does not leak and the gas production is normal, pressure should be generated.

If there is no pressure in the book width, there is a possibility of air leakage or water leakage; b. No gas production; c. The pressure gauge is broken.

1. In the past, it was generally pointed, with a maximum of 10 kPa (kPa). The table has a number of 1 10. The pointer points to 2, which is 2 kPa (kilopascals).

2. Now it is generally a red liquid water column type, and the maximum is 10 kPa (kPa). There are also numbers of 1 10 on the table. When the red liquid water column rises to 2, it is 2 kPa (kilopascals).

3. 1 kPa (kilopascal) is equal to the atmospheric pressure of the centimeter water column.

4. The maximum pressure in the general biogas digester is about 1 meter of atmospheric pressure of the water column.

5. The pressure in the biogas digester is closely related to the depth of the water pressure tank. The general depth of the hydropressure box is about meters. The deeper the pressure tank, the greater the pressure in the tank.

6. A column of water with a standard atmospheric pressure equal to a meter.

Generally, the maximum pressure in a biogas digester is about 1 meter of atmospheric pressure of the water column.

Summary. Dear , in general, the common digester pressure range is between megapascals (MPa), which is between 200-5000 millibars (mbar). It is very important to maintain proper digester pressure, as too high or too low pressure can adversely affect the safety and operation of the biogas system to a certain extent.

Too high a pressure can lead to a risk of a digester**, while too low a pressure will affect the efficiency of biogas generation and utilization.

Dear , in general, the common biogas digester pressure range is between megapascals (mpa), i.e. between 200-5000 millibars. It is very important to maintain proper digester pressure, as too high or too low pressure can adversely affect the safety and operation of the biogas system to a certain extent. Too high a pressure will lead to a risk of the digester**, while too low a pressure will affect the production and utilization efficiency of the biogas.

What does millibar mean.

The mbar is a unit of pressure that is one-thousandth of the bar. Bar is the unit of pressure in the International System of Units and is expressed as Pascal (PA). A chain of 1 bar is equivalent to 100,000 pascals (pa), while 1 millibar is equal to pascals (pa).

So, 1 bar is equal to 1,000 millibars. Millibars are often used to measure the relatively low pressure of gases or liquids. For example, atmospheric pressure is often expressed in millibars, usually between 900 and 1100 millibars.

a. Do not put chemicals in, such as washing water, hair washing water, bathing water, because it contains chemical ingredients, so it cannot be used if there is gas.

b. It has something to do with the weather, there is not a lot of gas, because the material put in does not reach the desired temperature to allow it to ferment.

c. There are too many stale materials in the biogas digester, which should be cleaned once a year.

The difficulties in the use of biogas digester are mainly due to the following problems:

1. The quality of the pool. At present, many biogas digesters are not built according to the regulations at all. Moreover, there is no quality acceptance before use in accordance with the provisions of the national standard. That is, to test the water and pressure. As a result, the quality of many biogas digesters is not up to standard at all, and water and gas leakage occur after feeding.

2. The popularization of farmers' knowledge is not in place. After the construction of biogas digesters in many places, there is no technical guidance for farmers at all, resulting in some very simple problems that have not been solved.

3. The problem of difficult discharging cannot be solved. In fact, this question is also a very simple question. But it is also a major constraint to development. pens have been subjected to technical research. However, it is difficult to promote.
