Improved biogasification plant based on biodegradable waste

Abstract

The invention comprises a biogas producing apparatus comprising gas holder drum (5), a digester (9) and comprising at least one of the features selected from the group of: (a) the said gas holder drum having scum breakers which may be any structural feature attached on one end to the guide pipe (3) and to the other end of the inner wall of the gas holder drum (5), (b) the said gas holder having a central pipe (a guide pipe), (c) an inlet pipe (2) that is integrated with the gas holder, (d) that may be attached to the central pipe, (e) a built in structural design feature of the said gas holder that provides scum breakers (4) that break up the floating scum and stirs the fermenting input organic matter with the movement of the gas holder up and down, as well as controlled rotational movement, (f) providing draining of digested slurry through an arrangement of outlet pipe (8) such that the pipe originates inside the digester tank near the upper end, (g) pipe (8) is provided at its bottom with an emergency slurry drain (11), (h) providing an outlet water drain (10) which connects to the water jacket, (i) providing a substrate drain (12) for emptying the contents of the digester whenever required, Q) providing a water jacket (7) to prevent the organic waste in digester from getting exposed to open atmosphere, preventing leakage of gas to atmosphere and for thermally insulating the digester. The biogas producing apparatus of this invention can be assembled in a single piece without projecting parts that is convenient for packaging and transportation., and in varying capacities including a kitchen model for digesting kitchen waste and / or a wide spectrum of organic wastes and may be painted in black for a better thermal efficiency. Digester may be made from Brick Masonry, Ferro-crete, Ferro-cement or R.C.C, while the gas holder of a fiber glass reinforced plastic (FRP), High Density Polyethylene (HDP) or any other non corrosive material.

Description

technical field [0001] The present invention describes an innovative and improved model of biogasification plant for the production of continuous high yield biogas from a range of various organic source input materials. Background technique [0002] Various organic wastes are generated every day, such as kitchen waste, vegetable waste, municipal biodegradable waste, hotel waste, farm waste or any other type of organic waste. These wastes are usually subjected to anaerobic digestion, resulting in the production of methane. This biogas would become a greenhouse gas if released directly into the atmosphere, however, if properly channeled this methane can be used as biogas and the digestate can be used as organic fertilizer. [0003] A traditional biogas plant is a buoy type biogas plant consisting essentially of two barrels or tanks, one of which is essentially made of mild steel with an opening and is held in the other tank in an upside-down position. The inverted tank has a...
