Nowadays, with the construction of a new countryside, biogas digesters have become a favorite among farmers and farmers have installed biogas digesters. There are also many types of biogas digesters, such as digesters, glass steel digesters, plastic digesters, and red mud digesters. Is the glass steel digester easy to use?
Is a glass steel digester easy to use?
The specification of glass fiber reinforced plastic digesters is generally 6-10 cubic meters. In the process of utilization, the floor space is small, the planting facilities are convenient, the construction is rapid, and the requirements for different geographical areas and different geographical environments can be satisfied. In the course of utilization, it is not necessary to maintain the pool body, which brings users many conveniences and is welcomed by grand farmers friends. The advantages of FRP biogas digesters are as follows:
1. The glass fiber reinforced plastic digester has good strength, light weight, convenient transportation and installation. The product is made of new glass fiber reinforced plastic material. The product has good strength and light weight. The product consists of two half tanks, which can be stacked and transported conveniently and installed only. It takes half a day and can be used once it is installed.
Second, the mechanical properties of FRP biogas digesters are good. When the cold winter temperatures are low, the freezing of the ground may cause damage to the concrete biogas. The FRP biogas digesters have a certain degree of elasticity and will not be cracked by frozen soil.
3. The gas-tightness of the glass-fiber digester is good, and the results of the coherent research and application are reviewed. The biogas tank made of glass-fiber reinforced plastic material is selected to have good sealing performance, no seepage, and no leakage.
4. The gas production rate of FRP biogas digesters is high, the thermal conductivity of FRP is 1.42 kj/(mh), and the thermal conductivity of concrete is 5.44 kj/(mh). It can be seen that the heat loss of FRP is much less than that of concrete, so the higher production is guaranteed. Gas rate.
Fifth, the price of glass fiber reinforced plastic digesters is affordable, easy to accept for farmers, glass fiber reinforced plastic digesters because of advanced technology, so the cost is not high, the price and the cost of concrete methane tanks.
6. The use of glass fiber reinforced plastic digesters has a long service life. Fiberglass biogas digesters are resistant to aging and erosion, and their service life can be as long as 30 years.
7. The glass fiber reinforced plastic digester is convenient to handle and easy to handle. The product is equipped with a discharge device, which can conveniently extract the bottom sediment, and during the use period, no internal maintenance is required, so it is easy to manage and control.
VIII. FRP Digester Tanks Suitable Groundwater Levels In areas with poor ground foundations, there are many areas where the groundwater level is high, or where there are special foundations such as soft expansive soils or collapsible loess. This is not only troublesome for the construction of ponds, but also for a long time. Into the main pool and water pressure between the split, the overall design of this product, not affected by the foundation.
FRP biogas digester performance
The hollow plate lighting is used to cover the water pressure between the glass steel biogas digesters, which warms the biogas slurry. When the biogas is produced, the biogas slurry is heated by solar energy when the biogas pressure is released to the water pressure. When the gas is used, the biogas slurry returns from the inlet pipe to the fermentation room, thereby realizing the mid-temperature fermentation of the biogas and increasing the gas production rate of the biogas. The annual gas production is 2-3 times the gas production capacity of the common biogas digester. The glass fiber reinforced plastic digester is assembled into a modular structure, divided into upper and lower parts. The fermentation room is buried underground. The gas chamber is installed on the ground. The water pressure is at the top of the gas chamber. The interface between the hair chamber and the gas chamber is fixed with screws, and the glass glue seals. , Simple and reliable, convenient assembly and disassembly, water pressure between the biogas liquid out of the pipe and biogas into the pipe, hand pump, quick valve, level gauge and so on.
The use of glass steel digesters is mainly to solve the problem of large discharge of the digesters. The demolition of the gas chamber can be opened to discharge materials. When the slag is discharged, the personnel do not need to go to the pool and stand directly on the ground to discharge the slag, thus avoiding potential safety hazards. It can be directly discharged with a quick valve (when there is air pressure in the air chamber). A part of slag liquid can also be pumped out by hand. Once the material is quickly unloaded (specified material position), the biogas output should be based on the principle of in and out of balance. Maintain proper pH (neutrality), proper ratio of carbon to nitrogen (25:1), try to increase the temperature between fermentations and conditions, and stir frequently.
Installation of glass steel digesters
1, site selection
Generally, the installation of biogas digesters should be in a place where the terrain is flat, the soil is good, and the leewards are sunny. Do not build in low-lying and difficult-to-drain areas. Also, do not build the pool where there is heavy traffic and strong shocks from passing vehicles, so as not to affect the biogas digesters. Normal use.
Biogas digesters should be as close as possible to toilets and pigsty, so that they can be easily and timely fed and fed. At the same time, the distance between the biogas digester and the kitchen should not exceed 30 meters to avoid low pressure and small fire due to long gas pipelines and excessive turning.
2, draw line
After the location of the biogas pit pit is selected, we must determine the diameter of the pit based on the size of the pool. Take the example of an 8-m3 methane tank. We must first fix the pile in the center of the selected pit area, then use a rope to tie it to the stake, measure the length of the rope with a ruler to 1.5 meters, and then use wood. The center of the pile is the radius of the rope. Draw a circle with a diameter of 3 meters. After the circle is drawn, lime is used as a mark along the circle.
After the lime circle is sprinkled, we must select a point near the pig's lap or toilet as the feed point. Place the inlet container on top, draw a circle along the edge of the container, and sprinkle lime on the circled line. After the feed port is painted, we must measure the length of the outlet diameter with a ruler on the other side and determine the position of the center point. Draw a semicircle with a wooden stick as the discharge area. Lime as a mark.
3, digging pit
Next, we will dig the pit along the lime line. First, dig out from the material outlet, and when it is dug, you can appropriately expand the interface of the digging line as the construction work surface. The pit we dug was spherical, with a pit depth of 2.2 meters, a central diameter of 3 meters, and a diameter of 2.8 meters below 1 meter. Measurements should be taken several times from different angles to ensure an agreement with the cell body. After the pit is dug, the inner wall of the pit body should be trimmed to make it smooth, and then the bottom of the pit should be eliminated to remove the hard objects such as bricks and stones. Finally, fill the pit with 10 cm thick sand and soft soil to protect the pool.
