NOVELTY - A suspension type biogas device comprises a fermenting storage pool, an air storage chamber, an air outlet conduit, a feeding hole, and a discharge hole; where the fermenting storage pool is of circular barrel shape, which is made of glass fiber reinforced plastics or polyvinyl chloride (PVC) material; the symmetrical surfaces of the storage pool are respectively equipped with the feeding hole and discharge hole; the upper part of the storage pool is equipped with the air storage chamber; and the air storage chamber is of pot cover shape, which is made of flexible PVC material.    USE - The suspension type biogas device is useful for industrial and commercial applications.    ADVANTAGE - The suspension type biogas device has stable gas generation performance, long service life, high strength, light weight, and high efficiency. Moreover, it can ferment and generate biogas by using the straw waste in the country and has the positive effect for protecting environment and saving energy.    DETAILED DESCRIPTION - A suspension type biogas device comprises a fermenting storage pool, an air storage chamber, an air outlet conduit, a feeding hole, and a discharge hole; where the fermenting storage pool is of circular barrel shape, which is made of glass fiber reinforced plastics or polyvinyl chloride (PVC) material; the symmetrical surfaces of the storage pool are respectively equipped with the feeding hole and discharge hole; the upper part of the storage pool is equipped with the air storage chamber; the air storage chamber is of pot cover shape, which is made of flexible PVC material; the top part of the air storage chamber is equipped with the air outlet conduit; the joints of the air storage chamber and fermenting storage pool are respectively equipped with several connected hanging buttons along the periphery; and when the biogas ferments and generates gas, the air storage chamber suspends above the fermenting storage pool with the action of the hanging button.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the suspension type biogas device.
