Large-scale sealed type gas and fluid integrated tank body and multiple gas pressure protecting device

Abstract

The invention relates to a large-scale sealed type gas and fluid integrated tank body and a multiple gas pressure protecting device. The large-scale sealed type gas and fluid integrated tank body is characterized by comprising an anaerobic fermentation tank of which the tank top adopts a conical structure, and a monofilm gas holder (5) which is mounted at the upper part of the anaerobic fermentation tank and below a conical top in a hanging manner, wherein the bottom of the monofilm gas holder is embedded in a water sealing tank (9) which adopts an annular structure at the middle and upper part of the tank body; the other end of a traction steel rope for hanging the monofilm gas holder (5) is connected with a gas capacity displaying counter weight (2) arranged outside the tank body; a mechanical gas pressure protecting device (1), a water sealing type gas pressure protecting device (3) and an electric gas pressure protecting device (4) are arranged outside the tank body.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation, in particular to an anaerobic biogas fermenter for gas-liquid integration and a multiple air pressure protection device thereof. Background technique [0002] Most of the gas-liquid integration tanks used in the anaerobic fermentation of the prior art have the following problems: [0003] 1. The gas cabinet is exposed, and the double-membrane gas cabinet is directly fixed on the top of the tank. The double-membrane gas cabinet can play a certain fixed function for laymen and can be directly placed outside. However, its material is polytetrafluoroethylene, which will age rapidly under the influence of natural factors such as wind, sun, rain and so on. In the absence of necessary protection, stones, branches, etc. may scratch the gas cabinet. Use an air pump to inflate and set the shape, and a gas cabinet protection device needs to be added, which increases energy consumption and i...

AI Technical Summary

Problems solved by technology

Use an air pump to inflate and set the shape, and need to add a gas cabinet protection device, which increases energy consumption and increases safety hazards

[0004] 2. Use a single air pressure protection device or even no protection device

Most anaerobic fermentation tanks use a water-sealed air pressure protection device, and the protection device is single

It is easily affected by too much or too little water, and there is a problem that the antifreeze is not replaced in time in winter or it is frozen due to improper use, losing its protective effect

A single air pressure protection device is not as safe as multiple protection devices, which is more reliable and safe
