Pool-stove-kang-kitchen-toilet five-in-one biogas production method for rural houses in cold areas

Abstract

The invention relates to a pool-stove-kang-kitchen-toilet five-in-one biogas production method for rural houses in cold areas, a biogas fermentation reaction pool is established at the lower part of a heated kang in the rural house in the north, the fermentation reaction pool utilizes a wall body of a foundation for thermal insulation, and flowing flue gas which passes through the heated kang simultaneously heats the biogas fermentation pool downwards for increasing the temperature. Indoor kitchen and toilet garbage and feces are directly discharged into the biogas fermentation pool, and plant ash of a stove is added in the biogas pool for regulating the pH and providing nitrogen and phosphorus inorganic matters. A pool body is respectively connected with all feed ports, a biogas storage chamber is isolated from the biogas fermentation pool, and biogas is stored in a gas storage tank at the roof through a gas guide pipe. All the facilities of the pool-stove-kang-kitchen-toilet are arranged in the same house, thereby not only being conductive to thermal insulation and biogas production, but also being easy to feed at any time, simultaneously facilitating the use of the biogas and realizing the centralized coupling of functions.

Description

technical field [0001] The invention relates to waste heat utilization and bio-fermentation technology of heated kang in northern rural areas, and specifically relates to a new high-efficiency biogas generator construction method. Background technique [0002] As a new type of renewable energy, biogas not only replaces and saves a lot of traditional energy, but also transforms and utilizes a lot of garbage, purifying the environment. The generation of biogas is through the fermentation of organic matter. Human and livestock manure, crop straw and crumbs, kitchen waste in domestic waste, sewage and sludge can be used to produce biogas. Biogas projects have been popularized and applied in my country for nearly 40 years. It has begun to take shape in many areas and has achieved remarkable social and economic benefits. [0003] However, the biogas production rate is significantly affected by temperature. Due to the more suitable climate in the south, the development of biogas pr...

Problems solved by technology

[0004] Aiming at the problem that the low temperature in winter in the northern cold region is not conducive to the operation of the biogas fermentation device, combined with the actual situation in the rural areas in the north, the purpose of the present invention is to provide a five-in-one biogas production device in rural areas in cold regions. method, this invention can not only solve the problem of low temperature of biogas digesters in cold areas in winter, but also better solve the problem of changing rural toilets into toilets
