Explosion-proof solar methane tank

Abstract

The invention relates to an anti-explosion solar energy methane-generating pit, which comprises a fermenting and aggregating box 8, a composite convex lens 2, a protective cover 1, a solar heat-collection plate 3, an anti-explosion heat-insulating container 4, an electric heating converter 5, a temperature sensor 6, a heat-insulating controller box 9, a quick fermenting and aggregating box 11 and a support saddle 7, wherein the anti-explosion heat-insulating container 4 is arranged on the upper part of the fermenting and aggregating box 8; the quick fermenting and aggregating box 11 is provided with an air vent 113 which is communicated with the fermenting and aggregating box 8, and the air vent 113 is arranged on the upper part of the inside of the fermenting and aggregating box 8; the anti-explosion heat-insulating container 4 is hermetically connected with a container cavity of the anti-explosion heat-insulating container 4 into a whole through the solar heat-collection plate 3, and hermetically arranged on the support saddle 7; and an input pipe 41, an input control valve 42, an output pipe 43, a pressure retaining valve 44, an insulator 46 and a wire sleeve 45 are arranged on the anti-explosion heat-insulating container 4. The invention can collect solar energy into a central position of the methane-generating pit, provide and control the required or optimum survival temperature or breeding temperature of methane backeria and the like, properly sort and treat gas-generating raw materials, and guarantee full utilization and safe use of organic waste and the methane-generating pit.

Description

technical field [0001] The invention relates to a biogas pond, in particular to an explosion-proof solar biogas pond which utilizes solar energy to heat up the biogas pond by concentrating light. Background technique [0002] Biogas is a new clean energy in rural areas of our country. Its effective use can solve the problem of insufficient resources for people to develop, reduce or eliminate the waste of people's living resources, and can be used as energy for people's lives. It mainly includes cooking and cooking. , heating water, heating, lighting, etc., can save a lot of coal, fuel and firewood, and improve the environment, high thermal efficiency. Biogas is a mixed combustible gas with methane as the main component, which accounts for 60%-70%. The methanogens that produce methane need to survive in the temperature range of 0-80°C, and they are respectively adapted to low temperature (20°C) and medium temperature (30°C). °C), high temperature (50 °C) bacteria, the most s...

Biogas is a mixed combustible gas with methane as the main component, which accounts for 60%-70%. The methanogens that produce methane need to survive in the temperature range of 0-80°C, and they are respectively adapted to low temperature (20°C) and medium temperature (30°C). °C), high temperature (50 °C) bacteria, the most suitable breeding temperature is 15 °C, 35 °C, 53 °C respectively, so the control of the temperature in the biogas tank and the living conditions of methane bacteria directly determines the output of biogas, when When the temperature is lower than a certain temperature (generally below 15°C), the feed liquid in the biogas digester cannot produce gas normally, so it cannot be used normally, thus limiting the popularization and application of biogas

Due to the limited ability of methanogens to digest organic matter, the current biogas digesters do not roughly distinguish the difficult-to-digest organic matter from citrus rods, which makes the organic raw materials not fully utilized, and it is not suitable to exclude output Post-biogas waste
