Description

Wet and dry solar biogas generator

technical field

The utility model relates to a biogas generator, in particular to a wet and dry dual-purpose solar biogas generator which prevents the sedimentation and encrustation of raw materials in the tank and makes the raw materials in the tank more fully gas-producing.

Background technique

Biogas is a new type of gas renewable energy, which not only provides the convenience of making full use of energy for people's daily needs, but also is conducive to environmental protection.

At present, some areas still use cement concrete biogas digesters. Due to many shortcomings, they have been improved to use glass fiber reinforced plastic biogas digesters. The popularization and use in rural areas of our country has achieved certain economic benefits and greatly saved energy. However, due to the need for a certain ambient temperature during the biogas fermentation process, and the cold weather in the north, the normal fermentation of organic waste cannot be guaranteed. For this reason, only wet fermentation is usually used, and the generated gas often produces solid particles and blocks the gas pipeline. It brings difficulties to maintenance; there are also movable biogas generators, which increase the cost and difficulty of operation due to structural changes.

In view of this, in order to overcome the above-mentioned shortcoming, the author develops the utility model according to actual experience and technical ideas.

The main shaft of the agitator is inserted into the tank through the above-mentioned sealed bearing, and the end of the main shaft is fixed on a fixed bearing at the bottom of the tank. The main shaft in the tank is equipped with a plurality of stirring wheels, and the biogas storage chamber is formed from the bottom of the sealing cover to the top of the tank. The sealing cover is equipped with a pressure reducing valve and a biogas outlet pipe passing through the support frame. have drains;

The inner wall of the tank is equipped with a solar heating tube, the air inlet and outlet of the solar heating tube are set on the top of the support frame, and an electronic fan is installed at the air inlet;

The top of the feed pipe is equipped with a sealing cover;

The lower end of the suction cylinder is provided with a suction hole, and the outer end of the suction cylinder is provided with a waste material discharge pipe, and a valve is installed on the waste material discharge pipe.

The tank body of the utility model is made of glass fiber reinforced plastics. Through the mobile solar heat storage tank, the solar hot air is transported to the tank body by an electronic fan, and then circulated in the tank body through a solar heating tube, so that the temperature in the tank body is increased to heat and ferment the raw materials. Greatly saves energy; the steering wheel-type agitator is equipped with multiple agitating wheels to prevent the raw materials in the tank from sedimentation and crusting, so that the raw materials can produce more gas and improve the efficiency of gas production; because the tank body is a fully enclosed structure, it is suitable for Dry and wet fermentation, over-dry and wet operation is convenient; the discharge device is suction type, and the fermented biogas slurry waste is drawn out through the waste discharge pipe, which is convenient for cleaning; thus solving the problem of preventing the raw materials in the tank from sedimentation and encrusting, and making the raw materials in the tank produce More sufficient air and dry and wet dual-use technical issues.

The utility model is simple in structure, and its advantage is as follows:

1. The tank body of this utility model is made of glass fiber reinforced plastics, and its fermentation technology adopts both dry and wet methods, which improves the service life of the generator.

2. The utility model improves the gas production, reduces the production cost, and has practicality.
