Abstract

An anaerobic fermentation methane pot of waste organic substances from urban and rural environment is composed of three parts: a first part (A) is a methane pot, of which the capacity is determined by design scale, wherein an electro-control residue stirrer is arranged in the methane pot and a residue liquid discharge outlet is arranged on the bottom of the methane pot; a second part (B) is a medium-high thermal-insulation layer which is made from a heat-absorption and thermal-insulation material, wherein the medium-high thermal-insulation layer maintains the temperature to be not less than 15 DEG C with power supply of solar energy and/or manual work; and a third part (C) is a dry-type gas storage pot used for storing methane after the methane is generated. A water discharge valve is arranged on the bottom of the pot and a gas-pressure meter or a biogas methane meter is installed on the top of the pot.

Description

Organic waste form anaerobic fermentation methane tank in urban and rural environment
Technical field
The present invention relates to organic waste form anaerobic fermentation methane tank in urban and rural environment.
Technical background
Along with the increase of social population, the development that agricultural, livestock industry (hereinafter referred to as farming animals animal husbandry) are produced, the active mud content of urban and rural environment middle peasant livestock industry organic waste and the discharge of sanitary sewage disposal (purification) factory is in increase, these organic wastes affect production environment and living environment, become one of environomental pollution source.
Utilize organic waste and active sludge in above-mentioned urban and rural environment to do to produce marsh gas raw materials, through anaerobically fermenting, the process of digestion microbial technique produces biogas.
Summary of the invention
Preparation methane gas producing feed liquid (above-mentioned discarded organic dry matter and water are mixed to form feed liquid per-cent), feed concentration produces biogas best results at certain proportional range.Drop into tank for sewage gas fermented feed liquid concentration different because of seasonal variation.Fermented feed liquid concentration too low or too high on generation biogas have impact.Methane gas producing amount is improved with biogas synergistic agent.
Ambient air temperature has a significant effect to methane gas producing amount.Time ambient air temperature low temperature (lower than 12 DEG C), anaerobion is difficult to survival and breeding, is unfavorable for producing biogas.Middle high temperature (higher than 15 DEG C) is conducive to anaerobion methanobacteria all living creatures and deposits and breeding, is conducive to producing biogas, effectively improves fire damp gas gas production rate.When temperature is lower than 15 DEG C, adds synergistic agent in feed liquid and improve fire damp gas gas production rate.
In this urban and rural environment, organic waste form anaerobic fermentation methane tank, is made up of three parts, and first part A tank for sewage gas, its amount of capacity is depending on design scale.The in-built Electronic control of joining of tank for sewage gas turns over slag device, and dreg discharging liquid mouth is established in bottom.Soak layer in second section B.With having the manufacture of heat absorption lagging material, by sun power and (or) insulation of manually powering, maintain the temperature at more than 15 DEG C.Part III C for generation of the dry gas-holder after fire damp gas, water discharge valve at the bottom of tank, top setting pressure table or fire damp gas strapping table.
Technical scheme
Organic waste and water prepare feed liquid by a certain percentage, and drop into form anaerobic fermentation methane tank Fig. 1 sectional view, Fig. 2 orthographic plan, carries out anaerobically fermenting.The matrix C/N of organic waste selects in certain limit.Tank for sewage gas is arranged on earth's surface also can be arranged on underground.
Fig. 1 is sectional view, Fig. 2 is orthographic plan, be described as follows: first part A organic waste and active sludge and water are mixed to form feed liquid by a certain percentage, drop into conveyer trough (pipe) (1), feed liquid enters tank for sewage gas (2), the in-built Electronic control of joining of tank stirs device (3), pot bottom dreg discharging liquid mouth (4), weather gage or methane gas strapping table (5).Part III C for generation of dry gas-holder (1) after fire damp gas, weather gage or fire damp gas strapping table (2), water discharge valve (3).

Claims (2)
