specific Embodiment

[0045] A specific example is as follows:

[0046] The total area of ​​the small hydrogen gas generator for households in villages and towns is only 2m2 2 , in which the overall size of the garbage crusher is 25cm×25cm, the length of the auger is 30cm; the height-diameter ratio of the hydrogen generator is 2:1, and the total volume is 1m 3 , the inner wall of the hydrothane generator is provided with 4-8 groups of triangular prism-shaped baffles 19, so that there is no dead angle inside the reactor, avoiding uneven fermentation and the formation of miscellaneous bacteria, and the full mixing of materials is achieved by beating and rotating, reducing the impact on mycelium The destruction of the body ensures the microbial activity in the fermentation process, and effectively improves the fermentation gas production and energy conversion efficiency. The volume ratio of the anaerobic hydrogen production chamber to the anaerobic biogas production chamber is 1:1. Both the hydrogen...

Abstract

The invention relates to a small-sized hydrogen methane fuel gas generation device for residents in villages and towns, wherein a garbage crushing and conveying device is connected with a feed port of a hydrogen methane generator through a packing auger; the crushed garbage is subjected to anaerobic fermentation in the hydrogen methane generator; a one-way openable valve of an anaerobic methane generation chamber is arranged between an anaerobic hydrogen generation chamber and the anaerobic methane generation chamber; the gas outlet end of a nanoceramic coating rolling shaft which runs through the center of the hydrogen methane generator is connected with a hydrogen purifier and a methane purifier respectively; purified hydrogen and purified methane are controlled by a gas mixing valve to be mixed and then are conveyed to a hydrogen storage tank; the hydrogen methane generator is arranged on a pedestal; a gravity lifting device is arranged between the pedestal and the hydrogen methane generator; a 360-degree rotatable universal wheel is arranged at the lower part of the pedestal; and brackets are arranged on two sides of the pedestal and are respectively used for fixing the packing auger, the hydrogen purifier and the methane purifier. The invention further provides a method for preparing hydrogen methane fuel gas by using the hydrogen methane generation device.

Description

technical field [0001] The invention belongs to the technical field of biological energy, and in particular relates to a small-scale hydrogen gas generating device for households in villages and towns. [0002] Another object of the present invention is to provide a method for preparing hydrogen gas by using the hydrogen gas generator. Background technique [0003] With the development of society and the improvement of villagers' living standards, it has 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 and human and animal manure from villages and towns in my country account fo...
