Description

Biogas digesters equipped with fully automatic FRP floating and sinking biogas hoods

technical field

The utility model generally relates to a biogas device, in particular to a biogas pool equipped with a full-automatic FRP floating-sink biogas cover.

Background technique

Biogas - it is an inexhaustible renewable energy construction. Over the past 30 years, the state has invested a lot of manpower, financial and material resources to support the development of biogas in rural areas, because it not only solves the living energy problem of rural farmers, but more importantly, it is used as fertilizer, feed, bait and "quasi-pesticide" . In the past, the brick-concrete structure was generally used to build biogas digesters. Because the brick-concrete structure requires a lot of labor, and the other is high investment. In addition, the structural performance is poor. Cement itself cannot be used as a sealing material, and it cannot meet the sealing standards at all. After a few years, the gas tank will start to crack, and basically 100% of the biogas digesters will leak water and air, making them unusable. In this way, many biogas digesters will leak after they are built. It lasts for more than ten years. Years or even decades of long-term neglect will cause great losses to farmers. Therefore, it is necessary to develop biogas equipment with better performance.

Utility model content

The purpose of the utility model is to provide a biogas digester equipped with a fully automatic FRP floating and sinking biogas hood which can overcome the shortcomings of the known technology, is more economical, convenient for construction and maintenance, and more reliable in use.

In order to achieve the above object, the solution of the utility model is: a glass fiber reinforced plastic cover is covered on the surface of the septic tank, the non-fixed type floats and sinks on the liquid surface of the pool, there is a cover stabilization device, and a gas guide pipe is connected from the cover. Group of biogas treatment and control devices.

Other proposals include: the biogas treatment device is a biogas purifier connected in series with a water-gas separator and a desulfurization biogas purifier on the outlet pipe leading from the inside of the hood. connected to gas equipment.

A fully automatic master controller is connected with the supercharging device, and the fully automatic master controller is an automatic switch, which controls the power supply system of the supercharging device to start or shut down.

With the above-mentioned scheme, the user does not need to build an expensive biogas digester, but only adds a cover to the existing septic tank, and adds the biogas treatment equipment and control equipment provided by the scheme to form a biogas operation system, which is very economical and convenient. It is also very reliable to get up, thereby achieving the purpose of the utility model.

The scheme will be described in more detail below in conjunction with the diagrams and embodiments.

Description of drawings

Fig. 2 is a front view of another biogas hood in the system shown in Fig. 1 .

Detailed ways

As shown in Figure 1, the entire biogas utilization system includes biogas collection and treatment processes. The advantage of this technical solution is that it does not need to build additional biogas digesters with special structures, and directly uses the existing cesspit structure of the farm. In the illustration, 1 is already Some cesspit are covered with a hemispherical arc-shaped glass fiber reinforced plastic floating cover 2. In rural areas, there are also situations where farmers build two adjacent cesspit. Shell-shaped arch arc can cover two cesspools, long convex shell-shaped arch arc 3 as shown in Figure 2, and this is understandable. The edge ring of the floating cover has a ring edge 4 to increase rigidity, and has a guide hole 5 at the top. The floating and sinking cover is usually made of glass fiber reinforced plastics, such as 191# resin plus thicker glass fiber cloth or felt, made by hand lay-up process, such as stacking 8 layers of 04# glass fiber cloth, the thickness of the shell is at least about 5mm, The strength and rigidity are good, and there is no problem with an object with a load of 300Kg on it. It has good corrosion resistance, acid and alkali resistance, and phenological properties. Because the shell is formed on the mould, the surface is smooth, sprayed with color, and it is a bright decoration to cover the cesspit of the farmhouse. Even if a fiberglass shell with a diameter of 2-3 meters is made, the weight is very light, no more than 80Kg, and two people can easily lift up the slope to climb up the ridge. Compared with it, its construction economy is obvious.

The floating cover is placed in the dung water, it is not fixed and free to float, and there is a guiding and positioning device to stabilize the floating cover. The cover guide positioning device includes setting a metal guide rod or pipe 6, usually made of stainless steel, passing through the guide hole 5 of the cover, and its upper end is fixed, and the said fixing includes fixing on the beam 7 of the building , often build pig-raising pens on the septic tank in rural areas in southern China, and the guide rods can also be fixed on the ring plate of the pens. This is understandable, and often adapts to local conditions.

The air guide pipe 8 extends into the inner space of the hood to conduct air, and its outlet pipe is connected with a group of biogas treatment devices. The outlet end is connected with a supercharging device 11, and its output end is connected with gas-using equipment, such as a water heater 12, a gas stove 13, a biogas lamp 14, and the like. Wherein the water-gas separator 9 is commonly used in the known technology, but the biogas purifier 10 of desulfurization is newly added, to protect the user's gas equipment, there are many kinds of booster devices, and the present embodiment selects the air pump, which is also the purpose of this invention. It is used for the first time in the system to increase the gas transmission capacity and ensure the gas consumption of water heaters and gas stoves.

There is also a biogas control device in the biogas operation system. A fully automatic master controller 15 is connected to the supercharging device 11. The fully automatic master controller is essentially an automatic switch, which controls the startup or shutdown of the power supply system of the supercharging device. The automatic master controller is connected with an automatic gas volume control device 16 arranged in the cover, and receives the signal of the gas volume automatic control device. When the gas volume is sufficient and the gas consumption device needs to be turned on, the switch is turned on, and the booster device is energized. When the gas volume is not enough to meet the standard Turn off the switch and turn off the power supply of the booster device, so as not to start the air pump and form a negative pressure in the cover, and the feces will enter the gas device through the pipeline, causing an accident.

With the above-mentioned device, the FRP floating-sink biogas hood can be mass-produced in the factory without on-site production, so the cost is low and the quality can be guaranteed. The biogas hood can be directly installed in the cesspit of the farmer's pigsty, and there is no need to carry bricks, sand, and stones , cement and other building materials, and cover the septic tank to seal the septic tank, so as to avoid the leakage of odor, reduce the breeding of mosquitoes and flies, and better solve the environmental sanitation in rural areas. These are the most popular among farmers for this technology. The characteristics of easy promotion, installation on the same day, gas production and use on the next day, while the brick-concrete structure must be cleaned and repaired in 3-5 years, and the FRP cover of this technology will never be repaired or refueled, and can achieve 100% sealing As a result, there will never be air leakage, and the use process is reliable and safe, so this is a practical technology.
