Abstract

The utility model provides a spherical hydraulic glass fiber reinforced plastic (GFRP) methane tank which comprises an upper semi-sphere and a lower semi-sphere, and is provided with a feed pipe and an air guide pipe. The feed pipe is slantways inserted into an air storage from the upper semi-sphere and stretches into a fermentation room of the lower semi-sphere; the air guide pipe is arranged at the top of the upper semi-sphere and is communicated with the air storage; a concave arc baffle is arranged at an outlet in the side wall of the upper semi-sphere; and the outlet is directly communicated with the side wall of a hydraulic room; and the gravity center of the hydraulic room props up the outer wall of the upper semi-sphere. The bottoms of the arc baffle, the outlet and the hydraulic room are at the same level. Because the outlet is directly communicated with the side wall of the hydraulic room, the hydraulic room and a methane tank are integrated, which saves floor area. As the outlet is arranged in the center of the tank, extra air can be discharged from the outlet when atmospheric pressure is excessive, which avoids the occurrence of tank explosion resulted from overlarge atmospheric pressure. The spherical hydraulic GFRP methane tank has simple structure, favorable air tightness, low production cost, convenient installation and maintenance and long service life.

(1) since on methane-generating pit episphere wall the discharge port of (sweathouse) be provided with the curved tailgate of an indent, this discharge port directly communicates with the water pressure house sidewall; The biogas amount that produces in sweathouse is bigger, when biogas is full of between gas storage, liquid in the sweathouse is owing to the pressure of biogas descends liquid level, when liquid drops to the curved tailgate bottom, biogas more than needed will be discharged from water pressure house along the curved tailgate wall, thereby the situation of avoiding quick-fried pond takes place owing to air pressure is excessive takes place.

(2) straight wall of water pressure house is arranged on the methane-generating pit episphere wall, and its center of gravity is supported on the body of pond, and water pressure house and fermentation vat are become one, and saved floor space, so the addressing of methane-generating pit is more convenient; And guarantee water pressure house not to be subjected to the influence of factors such as setting of ground and ground water table with being connected of fermentation vat and produce disengaging or be subjected to displacement, effectively guaranteed the safe handling of methane-generating pit.

(3) adopt heavy caliber through type feed-pipe, not only charging is convenient, and slags tap conveniently, thoroughly, makes tapping process convenient and swift.

(4) adopt glass-reinforced plastic material to make, can directly carry out aggregate erection at the scene, reduce the duration, reduce construction cost, have simple in structure, good heat preservation performance, advantage such as resistance to air loss is good, production cost is low, convenient for installation and maintenance, long service life, have popularizing value widely.Also can move and reuse after reinstalling.
