Novel flexible membrane material gas storage floating cover

Abstract

The invention discloses a novel flexible membrane material gas storage floating cover. The novel flexible membrane material gas storage floating cover mainly comprises a membrane material floating cover and balancing weights; the membrane material floating cover is in a cylindrical structure, the top of the structure is provided with an air ventilation nozzle and the bottom of the membrane material floating cover is open; the open bottom part is connected with the balancing weights through floating cover flanges and bolts in a locking mode; the gas storage and the gas supply are controlled and pressed by the self weight of the balancing weights, and the connection part of each balancing weight and the membrane material floating cover is also provided with a pressing block. Compared with the prior art, the novel flexible membrane material gas storage floating cover has the main advantages that the quality is stable; the service life is long; the requirements of methane storage and conveying pressure of the engineering system through the setting of the self weight of the balancing weights for the flexible membrane material floating cover gas storage device are met, and the running stability for applying the device engineering system can be improved effectively; the flexible membrane material floating cover is low in self weight, can be folded, is very simple and convenient in installation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of biogas generating devices, and in particular relates to a novel flexible membrane gas storage floating cover. Background technique [0002] Biogas is a combustible gas, which is mainly obtained by sealing organic waste such as feces and straw in a closed space, that is, a biogas fermentation tank, and fermenting it through microorganisms; with the strengthening of people's awareness of energy crises, people are more interested in low-cost biogas Renewable energy has attracted much attention; biogas engineering technology occupies an extremely important position in the development of new energy and ecological environment protection, and is used to solve energy problems, protect the ecological environment, and improve the living and sanitary environment. [0003] At present, the biogas devices that are mainly promoted and used at home and abroad and the main problems: 1. The current hydraulic biogas diges...
