Description

Fiberglass reinforced concrete two-combined biogas digester

technical field

The utility model relates to a biogas fermentation device, in particular to a glass-reinforced-reinforced-concrete two-combination type biogas pond.

Background technique

The biogas digesters commonly used in the prior art are constructed of bricks and cement, that is, brick-concrete biogas digesters, which have poor air tightness, take a long time to build, and are difficult to guarantee quality. Moreover, brick-concrete biogas digesters are not resistant to corrosion, are afraid of freezing, and are difficult to maintain. The short service life directly affects the use effect of the biogas digester.

Contents of the invention

The purpose of this utility model is to avoid the disadvantages of the above-mentioned prior art, and provide a relatively low cost, detachable transport, good air tightness, no air leakage, no fear of freezing, long service life, short pool building time, Easy-to-maintain glass-reinforced-concrete two-combination biogas digester.

The purpose of this utility model is achieved by the following measures:

A glass-reinforced-reinforced-concrete dual-combination type biogas digester, which is composed of a glass-steel arch cover 2, a biogas digester air duct 3, a concrete discharge room 8, a concrete biogas digester fermentation room 9, and a biogas digester feed cylinder 7, and is characterized in that the glass-reinforced concrete two The upper end of the combined biogas digester is hemispherical, and the opening of the hemispherical FRP arch 2 has an outwardly extending edge 5, and there are embedded parts 4 on the edge, and concrete is poured between the fermentation room 9 of the concrete biogas digester and the edge 5 of the FRP arch. Connection, there is a biogas tank air guide pipe 3 in the center of the top of the glass fiber reinforced plastic arch cover 2, and a cylindrical biogas tank feed tube 7 is closed to connect with the biogas tank fermentation room 9 on the side of the concrete biogas tank fermentation room 9, and the top of the biogas tank feed tube 7 has The biogas digester feed port cover 1 has a cylindrical concrete discharge room 8 on the opposite side of the biogas digester feed cylinder 7, and there is a discharge channel 10 between the concrete discharge room 8 and the concrete biogas digester fermentation room 9. The concrete There is a discharge room cover 6 at the top of the discharge room 8 .

Compared with the prior art, the utility model has the following beneficial effects:

1. Compared with the existing brick-concrete structure biogas digesters, the FRP arch cover of the FRP-concrete dual-combination biogas digester is produced in a factory, which can ensure the quality, high sealing performance, no air leakage, no leakage, easy transportation, and the construction time of the pond short;

2. It is not afraid of freezing and has a long service life. The temperature in the north is low in winter, and the ground freezing may cause damage to the brick-concrete biogas digester, while the fiberglass concrete biogas digester is 1.5 meters above the ground with a glass fiber reinforced plastic arch cover, which has good ductility, will not be damaged by freezing, and has strong corrosion resistance and acid resistance Durability, service life up to 30 years;

3. High gas production rate and good airtightness. The thermal conductivity of the fiberglass-reinforced-concrete dual-combination biogas digester is only 50% of that of the brick-concrete structure biogas digester, with small heat loss and high gas production rate.
