Description

Rural poultry house biogas generator

technical field

The utility model relates to a biogas generating device, in particular to a biogas generator mainly suitable for rural poultry houses.

Background technique

Existing rural biogas digesters are mainly formed by digging a pit near the poultry manure pit, and then using brickwork and mold concrete pouring to form it. Concrete is still a porous material. The edge length is only 0.25nm, so the voids of concrete are 6-12 times larger than methane molecules. Therefore, brickwork and concrete are used as the main structural materials of the biogas tank body, no matter how the construction is done, the main structural materials of the biogas tank body cannot be guaranteed, and the durable sealing of the biogas tank body cannot be guaranteed no matter what the construction, and brickwork and concrete are used for construction The cycle is long and the efficiency is low. Moreover, there are the following deficiencies: 1. The biogas pit needs to be set up separately, which increases the occupied area and increases the investment. 2. When the concrete biogas generator discharges the biogas residue or the water level drops, a certain negative pressure will be generated inside the biogas digester, which will cause certain damage to the biogas digester. 3. The concrete biogas generator does not have heat preservation and the temperature is low. The biogas is produced by the activities of a variety of anaerobic bacteria. The normal adaptation temperature of anaerobic bacteria is 8°C-70°C, and no biogas will be produced if it is lower than 8°C. , This is the reason why biogas projects in northern my country do not produce gas in winter, and it is not easy to operate with a separate heating device. 4. When the biogas generator reduces the biogas material or the water level is insufficient, the biogas pressure cannot be constant, especially it cannot meet the requirements of the biogas generator set for constant air pressure. 4. There is no circulation mechanism, so that the materials in the biogas tank cannot fully react to generate biogas.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems existing in the existing rural biogas tanks, and provide a biogas generator for rural poultry pens. The poultry manure pit does not need to dig another biogas pit, which reduces the investment, and does not need concrete pouring, and is tightly sealed. The material can generate biogas more fully and increase the biogas output.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

A biogas generator for a rural poultry house, comprising a biogas tank and a biogas chamber, characterized in that: the biogas tank and the biogas chamber are arranged in a cesspit under the poultry house, and the feed port of the biogas tank is connected to the outlet of the poultry house The feed port is connected, and a slag discharge port is set on the biogas digester.

The utility model also includes a circulation fan, the air inlet of the circulation fan is located in the biogas chamber, and the air outlet is located at the bottom of the biogas pool.

The biogas digester and the biogas chamber are integrated, and the biogas digester and the biogas chamber have a double-layer structure, including an inner membrane with toughness that can expand and shrink and an outer membrane with toughness that can expand and shrink.

The utility model also includes a heating device, and the heating device is located between the biogas pool and the biogas pit.

The heating device is an electric blanket.

The advantage of adopting the utility model is:

1. In the utility model, the biogas tank and the biogas chamber are arranged in the cesspit under the poultry house, the feed port of the biogas tank is connected with the discharge port of the poultry house, and a slag discharge port is arranged on the biogas tank. The poultry manure pit reduces the occupied area, and utilizes the original poultry manure pit without digging another biogas pit, which reduces investment and is easy to operate and popularize.

2. The air inlet of the circulating fan of this utility model is located in the biogas chamber, and the air outlet is located at the bottom of the biogas tank. The biogas in the biogas chamber is used for self-circulation, and the materials in the biogas tank are circulated and stirred, so that the materials in the biogas tank can react more completely and improve the biogas efficiency. output, ensuring a stable pressure in the biogas chamber.

3. The utility model is provided with a heating electric blanket between the biogas pit and the biogas pit, and the heating device can be used to adjust the temperature in the biogas pit, promote the reaction of materials, and increase the biogas output.

4. Since the space between the inner membrane and the outer membrane is filled with air, it has the effect of heat preservation on biogas. Even when the outdoor temperature is as low as -30℃, the temperature inside the inner membrane can still reach above 15℃.

5. Since the inner membrane is a soft material membrane structure with toughness and expandability, it can shrink or expand according to the gas capacity of the biogas chamber. This adjustment function prevents the biogas chamber from generating negative pressure and avoids damage caused by negative pressure .

6. Due to the use of membrane structure, the gas storage capacity is increased and the service life is improved.

7. The construction period is short, generally 10-15 days can be fully completed and put into use, which improves work efficiency.
