Abstract

The utility model provides a large-scale glass fiber reinforced plastics biogas digester, which comprises a green body of the biogas digester. The large-scale glass fiber reinforced plastics biogas digester is characterized in that: the green body of the biogas digester is provided with a glass fiber reinforced plastic layer. The large-scale glass fiber reinforced plastics biogas digester adopts ZWD type large-scale biogas digester and uses brick setting as support and filling to brush glass fiber reinforced plastics on the inner layer or outer layer of the biogas digester or both the inner and the outer layers, thus solving the insulation problem of the biogas digester and guaranteeing the gas production rate; the sealing performance is good; compared with concrete pouring, the cost of the glass fiber reinforced plastics biogas digester does not increase.

Description

Large glass steel methane-generating pit

Technical field

The utility model relates to a kind of large glass steel methane-generating pit.

Background technology

The concrete casting of large methane tank application now forms, and exists heat insulation effect poor, and winter temperature is lower, and then factor of created gase is low, not even aerogenesis; Need smear problems such as sealing agent antiseep, gas leakage.

Summary of the invention

The purpose of this utility model provides a kind of large glass steel methane-generating pit, and not only heat insulation effect is good for this methane-generating pit, good airproof performance, and cost is low.

Large glass steel methane-generating pit of the present utility model comprises the methane-generating pit base substrate, it is characterized in that: described methane-generating pit base substrate is provided with frp layer.

Remarkable advantage of the present utility model is: the utility model adopts ZWD type large methane tank, utilizes brick work to support and filling, at the outer or inside and outside two-layer brushing glass reinforced plastic of methane-generating pit internal layer, has solved the insulation problem of methane-generating pit, has guaranteed factor of created gase; Good airproof performance; And its cost is compared with concrete casting, does not increase.
