Automation solar energy biogas fermentation method and device

Abstract

The invention relates to an automation solar energy biogas fermentation method, which belongs to the fields of environmental protection and chemical engineering. Aiming at the defects in the conventional biogas production process, the invention provides an automation solar energy biogas fermentation method and an automation solar energy biogas fermentation device, which can implement the steps of feeding, stirring, discharging, constant temperature and quantifying automatically in the north part of China in winter. The automation solar energy biogas fermentation method comprises the steps that: an automatic feeding delivery pump sends feces mixture in a feces collection pool into a material tank in a hydrolytic acidification treatment tank to carry out the hydrolytic acidification treatment; after being treated by the hydrolytic acidification treatment tank, the feces mixture is sent to a material tank in an anaerobic digestion tank by an automatic feeding pump; a solar thermal collector sends hot water into water collection interlayer of the hydrolytic acidification treatment tank and the anaerobic digestion tank by a temperature controlled pump and a solar energy hot water circulation system; and generated gas is injected into a gas holder for users to use after the treatment of desulfuration and solid-liquid separation. The automation solar energy biogas fermentation method and the automation solar energy biogas fermentation device are established on the basis of automatic program control of biogas feeding, stirring, discharging, constant temperature and quantity limitation, and correspond to the current development situation of the farmers of the animal breeding in China at present.

Description

Technical field: [0001] The invention belongs to the field of environmental protection chemical industry, in particular to a biogas production method and device. Background technique: [0002] At present, the "four-in-one" biogas project has been promoted in the northern rural areas of my country for more than ten years. The main problems exposed during the demonstration and promotion process are: affected by the severe winter climate in the north, little or no gas is produced, and the risk of leakage Leakage, freezing, cracking, and scrapping occur from time to time. On the other hand, it cannot automatically feed, stir, and discharge materials, which is labor-intensive in popularization and application. Although since 2005, the northern part of my country has invented an iron tank fermentation process that can produce gas and survive the winter, but the real automatic feeding, stirring and discharging have not been realized in the application. In particular, no real harmle...

Problems solved by technology

[0002] At present, the "four-in-one" biogas project has been promoted in the northern rural areas of my country for more than ten years. The main problems exposed during the demonstration and promotion process are: affected by the severe winter climate in the north, little or no gas is produced, and the risk of leakage Leakage, freezing, cracking and scrapping occur from time to time. On the other hand, it cannot automatically feed, stir, and discharge materials, which takes a lot of time and effort in popularization and application.

Although since 2005, the northern part of my country has invented an iron tank fermentation process that can produce gas and survive the winter, but it still has not realized the real automatic feeding, stirring and discharging in the application.

In particular, no real harmless treatment and zero discharge have been realized.
