Description

A biogas recycling device

technical field

The utility model relates to a methane recycling device.

Background technique

Using plant residues or fecal sludge to produce usable biogas through a series of functions in the case of isolation from the air has been used more and more in some rural areas of our country. In the prior art, pits are generally dug on the ground, and tanks are generally made of cement and bricks, which are formed by artificial masonry. This type of structure has obvious disadvantages, such as difficult maintenance, unstable pressure in the pool, and no biogas can be produced at all in cold winter areas. In addition, the gas leakage rate of the biogas digester is high and the gas production rate is low, which is difficult to meet people's needs.

Utility model content

The technical problem to be solved by the utility model is to provide a biogas recycling device with convenient installation and maintenance, relatively stable biogas output and convenient cleaning.

In order to solve the above technical problems, the utility model takes the following technical solutions:

A biogas recovery and utilization device, comprising a biogas pit, a feed pipe passing through the upper surface of the biogas pit and inserted into the lower part of the biogas pit, a sewage discharge pipe is installed on the side wall of the bottom of the biogas pit, and a pipe connected to the interior of the biogas pit is provided on the upper end of the biogas pit. A gas storage room, the gas storage room is connected with an air outlet pipe, a heating pipe is arranged in the biogas pool, and a solar heat collecting plate is installed on the outer wall of the biogas pool.

The lower port of the feeding pipe is provided with a plugging cover with one end movably connected with the feeding pipe, and a traction rope is installed on the blocking cap, and one end of the traction rope is led out from the upper port of the feeding pipe.

An end cover is arranged on the upper port of the feeding pipe, and the traction rope is led out through the end cover.

The heating pipe is connected with the pipeline of industrial waste water or waste gas.

The utility model has a compact structure, uses industrial waste water or waste gas for heating, and adopts solar collector plates to absorb heat at the same time, double heating, the temperature in the pool rises quickly, and at the same time effectively reduces the loss of heat, and is less affected by the external environment. Production is relatively stable. In addition, a plugging cover is installed at the lower port of the feeding pipe, and the plugging cover is used to block the lower port of the feeding pipe through the traction rope. As the pressure in the pool increases, the residue will be automatically discharged from the sewage pipe, which is convenient for cleaning and less labor intensive. , easy to install and maintain. Through the exhaust pipe, the generated biogas is transmitted to the family for cooking, cooking, boiling water, etc., or connected to the machinery and equipment through pipelines, as the fuel for the machinery and equipment, which greatly saves the cost.

Accompanying drawing 1 is the utility model sectional structure schematic diagram.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a biogas recycling device includes a biogas digester 1, a feed pipe 2 that passes through the upper surface of the biogas digester 1 and is inserted into the lower part of the biogas digester 1, and is equipped with a sewage discharge pipe on the bottom side wall of the biogas digester 1. Pipe 3, a gas storage chamber 4 communicating with the interior of the biogas digester 1 is provided on the upper end surface of the biogas digester 1, and the gas storage chamber 4 is connected with a gas outlet pipe 5. A heating pipe 6 is arranged in the biogas digester 1, and the outer wall of the biogas digester 1 is installed Solar collector panels7. The heating pipe 6 communicates with the pipeline of industrial waste water or waste gas. The lower port of the feed pipe 2 is provided with a plugging cover 8 that is movably connected with the feed pipe 2 at one end, and a traction rope 9 is installed on the plugging cover 8, and one end of the traction rope 9 is drawn from the upper port of the feed pipe 2. An end cap 10 is arranged on the upper port of the material tube 2, and the traction rope 9 is drawn out through the end cap.

The utility model not only utilizes waste water and waste gas with waste heat in the industry for internal heating, so that the substances in the biogas pool react to generate biogas, but also utilizes the solar heat collecting plate arranged on the outer wall of the biogas pool to absorb heat, so that the temperature in the pool can be heated up quickly at the same time , and it is not easy to lose heat, the biogas output is relatively stable, and is less affected by the external ambient temperature. It is also possible to operate the traction rope to make the plugging cover block the lower port of the feed pipe, and as the pressure in the tank increases, the completely reacted residue is discharged from the blowdown pipe under the pressure of the air pressure, which reduces the labor intensity. When cleaning is not needed, release the traction rope, and the plugging cover leaves the lower port of the feed pipe.
