Small-size biological hydrogen-producing device for rural family

Abstract

The invention relates to a small-size biological hydrogen-producing device for a rural family. A rubbish breaking device is connected with a feeding port of a hydrogen-producing reactor through an auger; the interior of the hydrogen-producing reactor has a double-reaction area structure which is composed of an aerobiotic pretreatment chamber and an anaerobic digestion hydrogen-producing chamber; the broken rubbish is respectively subjected to aerobiotic pretreatment and anaerobic digestion hydrogen production; a valve which can be unidirectionally opened by facing to the anaerobic digestion hydrogen-producing chamber is arranged between the aerobiotic pretreatment chamber and the anaerobic digestion hydrogen-producing chamber; a nanometer ceramic film-coating roller for collecting hydrogen and aerating penetrates through the center of the hydrogen-producing reactor; a gas outlet end of the nanometer ceramic film-coating roller is connected with a hydrogen-film separating device for purifying and drying the hydrogen in biogas; the hydrogen-film separating device is connected with a molecular sieve hydrogen storing device; the hydrogen-producing reactor is mounted on a base; a 360-degree ratable universal wheel is mounted on the lower part of the base, so that the device is convenient to move and place; and brackets are arranged on two sides of the base and are respectively used for fixing the auger and the hydrogen-film separating device. The invention also provides a method for preparing the hydrogen by utilizing the device.

Description

technical field [0001] The invention belongs to the technical field of biological energy, and in particular relates to a small-scale biological hydrogen production device for rural households. Background technique [0002] With the advancement of the construction of a new socialist countryside, while the living standards of villagers have improved, it has also brought about environmental pollution and waste of resources in villages and towns. According to reports, my country is the country with the largest output of rural organic waste in the world, about 4 billion tons per year, including 2.61 billion tons of livestock and poultry manure, 700 million tons of crop straw, and 25,000 tons of discarded agricultural film and other plastics. , 100-150 million tons of vegetable waste. Among them, organic waste from domestic sources in villages and towns, human feces, and organic waste from village and town service industries account for a relatively large share, resulting in rando...

Problems solved by technology

However, due to the scattered and mixed waste in villages and towns, existing biological hydrogen production reactors have problems such as high pretreatment requirements, slow start-up, unstable operation, low gas production rate, high energy consumption, and large floor space.
