Description

Mobile Solar Biogas Plant

technical field

The utility model relates to a biogas generating device, in particular to a mobile solar biogas device.

Background technique

Biogas is a mixture of gases, which contains 60%-70% of methane, and also contains carbon dioxide, hydrogen sulfide, nitrogen, carbon monoxide, etc.; The flammable gas produced by the fermentation of microorganisms in the biogas tank under the conditions of humidity, humidity and acidity. It has the characteristics of high efficiency, energy saving, and environmental protection. It can be used like liquefied petroleum gas. It is widely used in cooking, cooking, watering, heating, lighting, etc. The biogas residue produced after use is an organic fertilizer. Some existing underground biogas digesters are immobile, gas production is slow, low and unstable, and some biogas devices still have the defects of narrow raw material range, few application functions and waste of energy.

Utility model content

The purpose of the utility model is to provide a mobile solar biogas device to overcome the disadvantages of the prior art, such as unstable gas production, low gas production efficiency, inconvenient movement, and poor energy saving and environmental protection effects.

The purpose of this utility model is to realize through the following technical solutions:

Mobile solar biogas device, including biogas reaction tank, solar heater, biogas safety valve, high-efficiency desulfurizer, gas-water separator, exhaust pipe, wherein the upper end of the biogas reaction tank is provided with a feed port, and the lower part of the biogas reaction tank sphere is equipped with There is a discharge port; the solar heating device is a circulating all-glass vacuum heat collecting tube solar heater, which uses the high absorption rate and low emissivity of the vacuum heat collecting tube to convert the absorbed solar radiation into heat energy, and utilizes the specific gravity of cold water Large, hot water has the characteristics of small specific gravity. In the vacuum tube, a natural circulation of cold water from top to bottom and hot water from bottom to top is formed, so that the temperature of the whole water gradually rises to achieve the effect of heating the biogas tank. The solar heater The vacuum tube goes deep into the biogas reaction tank through the feed port; one end of the exhaust pipe is inserted into the feed port, and there are biogas safety valves and pressure gauges on the exhaust pipe from right to left. The safety valve should be installed vertically on the upper part of the exhaust pipe. When the pressure of the biogas pipeline exceeds 14Kpa, the safety valve will automatically exhaust, and when the pressure drops to 12Kpa, it will automatically close the valve; the pressure gauge is connected by the inlet joint and the membrane engineering plastic shell to form a sealed air chamber, and the gas pressure pushes the machine to rotate Move to make the pointer display the pressure on the scale. The meter is used to measure the gas storage capacity in the biogas tank; the air inlet of the pressure gauge is connected between the gas pipeline of the biogas tank and the stove with a three-way pipe, preferably 2 meters away from the stove. Install within 1 meter, and the height from the ground is not less than 1.5 meters, which is convenient for observing the pressure and keeping the surface clean; one end of the exhaust pipe is connected to a biogas lamp, and the other end is connected to a biogas stove after passing through a high-efficiency desulfurizer and a gas-water separator. Contains a small amount of hydrogen sulfide, which is corrosive to the stove and various accessories, and shortens the service life of the product. Hydrogen sulfide and its gas are harmful to the human body and the environment. After using the desulfurizer, it can effectively remove hydrogen sulfide, gas water The separator is mainly used for the purification of the mixed gas.

The beneficial effects of the mobile solar biogas device described in the utility model are: using solar energy resources to transport heat to the biogas reaction tank to increase the temperature in the tank, so that it can generate uniform and stable biogas, and improve the gas production efficiency; biogas The tank can be moved conveniently at any time, with a wide range of raw materials; it has multiple application functions, saves a lot of energy, and achieves a good environmental protection effect.
