Description
Technical field
The utility model belongs to bioenergy and environmental protection field, relates to a kind of sampling loop continuous monitoring type anaerobic fermentation tank specifically.
Background technology
Biogas technology is a kind of the biomass waste material to be utilized mode by the clean energy that biochemical reaction is converted into energy biogas, because of having biogas, the processing of waste of production, killing characteristics such as pathogenic bacterium and be widely used.China's biogas development at present is still based on the rural area small-sized methane tank, and along with the raising of people to energy-saving and emission-reduction understanding, and to the increase of clean energy demand, and to the needs of waste water treatment, big-and-middle-sized biogas engineering more and more is subjected to the attention of society and country.But, there are a series of problems because domestic big-and-middle-sized biogas engineering just grew up in recent years:
(1) marsh gas fermentation processes instability.In fact, the generation of biogas is the complex biological degradation process that is participated in by hundreds of anaerobion flora, is the collaborative and group effect of microorganism, and this and aerobic fermentation have very big difference, and whole biogas process is just as " black box operation ".These characteristics are reflected on the engineering be we can say, it is relatively easy to build biogas engineering, and operation biogas process is but very difficult.In fact a lot of biogas engineerings have moved long-time back and just problems such as low, the easy acidifying of gas producing efficiency, material overload and material scum silica frost crust occurred, and this also is one of bottleneck of the permanent development of puzzlement biogas engineering.The major cause that these problems occur is that the biogas worker fails fully to understand to the biogas process, and problems such as material scum silica frost crust are then in close relations with alr mode.The main alr mode of existing biogas engineering has the tank body center to stir, gas stirring, or the stirring of tank body bottom etc., these several alr modes are because the restriction of action principle, all can not prevent material crust simultaneously, or the generation of scum silica frost, thereby directly influence the output of biogas.
(2) utilization efficiency of heat energy is low.Current, the maximum technological difficulties of particularly promoting biogas work both at home and abroad in vast farming and pastoral area are that the temperature of the winter or the whole year is low excessively, are unsuitable for the growth and the aerogenesis of methane fermentating microorganism.At present the means that heat of biogas jar common exist the heat energy transformation efficiency low, pollute problems such as big, the requirement of incompatibility large-sized biogas engineering development.In addition, the northern area of China winter time is long, temperature is low, how anaerobic reaction-pot is added gentle insulation, is the important factor whether anaerobic reaction can works better, directly has influence on the production of biogas.Concerning steel silo, existing common heating process is external wall heating process.This processing method is that the thermal cycling heating tube is coiled in the anaerobism tank wall, and thermal source reaches reaction mass by heating tube and anaerobic reaction tank skin.The drawback of this method maximum is that Heating temperature is inhomogeneous in the retort, and in addition, heating tube is installed in the tank body outside, and to cause thermo-efficiency to utilize low, though the heating tube outside has lagging material to be incubated, but still has caused the loss of part heat.
(3) front-end investment is big.The gas holder that biogas engineering is commonly used is a bell-jar wet type biogas gas storage holder, this gas storage holder be with a U-shaped bell jar left-hand thread in filling the tank body of water, biogas enters bell jar and ullage space by tank body bottom inlet mouth through water liquid, and the increase of biogas amount and minimizing can make the metal bell jar move up and down so that adjust gas storage space.This gas storage holder shortcoming is that cost is higher, and heat-preserving equipment is not arranged, and when temperature is reduced to below 0 ℃, can not use behind jar intravital water freezing.In addition, fermentor tank and the biogas storage gas holders of adopting are built respectively more in the existing biogas engineering.In fact to be integrated be a kind of way of doulbe-sides' victory for fermentor tank and gas-holder, both can reduce construction investment, can optimize land use again.
