Description
Technical field
The present invention relates to a kind of device of charging, more particularly, the present invention relates to a kind of anaerobically fermenting engineering that is mainly used in, with the device of the matching used full mechanically driver type charging of high solid concentration (TS >=8%) anaerobic reactor.
Background technology
In organic waste, contain a large amount of organic compositions, as carbohydrate, protein, fat and Mierocrystalline cellulose etc., it is the large biomass resource of fine quality of wide material sources, amount, build big-and-middle-sized biogas engineering---using anaerobic digestion techniques to process organic waste is the sustainable development that promotes that urban and rural economies are built, and realizes the important means of energy environment protection double benefit.At present, the organic solid castoff surpassing in Europe more than 10% adopts anaerobic fermentation technology to process.
Anaerobic reactor comprises that its auxiliary facility (discharging system, process pipe etc.) is the kernel processing device of biogas engineering, the overall operation efficiency of engineering, work-ing life, economic benefit etc. are had a direct impact, should design and optimize according to composite factors such as treatment scale, raw material type, zymotechniques.Anaerobically fermenting can be divided into liquid state fermentation (TS≤8%), high solid concentration fermentation (8%<TS<20%) and solid state fermentation (TS >=20%) three classes by fermentation total solid concentration; By reactor design type, can be divided into upflowing, completely hybrid and piston-type etc.The high solid concentration anaerobically fermenting of TS >=8%, relying on its high organic loading, high pond to hold the significant advantages such as factor of created gase, high reactor utilization ratio and low water usage amount (reducing natural pond liquid processing pressure) becomes the developing direction that anaerobically fermenting is processed organic waste, and corresponding reactor mostly is completely hybrid (CSTR).Countries in Europe (as Sweden, Germany) adopts this type of anaerobic ferment process and reactors more at present, at home still in the starting stage.
Aspect anaerobic reactor, current research and report are substantially all to carry out around inside reactor structure, as feed system and the sampling unit of auxiliary facility, seldom relate to.Adopt high solid concentration anaerobic ferment process, especially the high fiber-like plant (stalk, energy grass etc.) of take is raw material, due to characteristics such as its density is low, easy adhesions, its feed system, as adopted the mode of traditional equalizing tank+pumping, is easy to occur that raw material is hung pool wall, material water pump send the problems such as ratio is improper, pump obstruction; Ram pump is not suitable for the conveying of loose raw material.Abroad the feeding manner for this type of raw material adopts material more, water is carried respectively, and the conveying of material adopts worm conveyor substantially, but the screw conveying feeding system adopting both at home and abroad at present only has the improvement stage to adopt Mechanical Driven, afterwards completely by gravity make raw material voluntarily landing enter inside reactor, the drawback of this mode is: the landing stage is owing to there is no Mechanical Driven voluntarily, if the speed of improvement stage transferring raw material (the especially low and loose high fiber-like raw material of density) is greater than the landing stage, be easy to form descending section of obstruction of charging, thereby cause feed system running not normal, to such an extent as to overall operation pauses, if utilize the method for reduction improvement stage transferring raw material speed to avoid the generation of above-mentioned phenomenon, can make feed system inefficiency.In addition, the helical conveyer system using both at home and abroad at present, feed-pipe is directly communicated with reactor top, need to take necessary seal approach to helical conveyer system, to prevent that gas from being leaked by source material delivery system, thereby has improved cost; Moreover raw material is to be directly freely scattered in the upper surface of anaerobically fermenting feed liquid by reactor top, even if reactor is CSTR, can make material and fermented feed liquid lump together, but the time is longer by stirring.Must there is a kind of more advanced method and apparatus to be developed and to apply, to solve above various shortcoming and the drawbacks that are applied at present the feed system of high density anaerobic fermentation reactor (especially comprising high fiber-like raw material in raw material).
Sampling is a requisite link in biogas engineering, is the necessary means of obtaining feed liquid parameter in anaerobic fermentation system.In current big-and-middle-sized biogas engineering both domestic and external, be substantially all the mode that adopts " valve+pipeline ", utilize hydraulic pressure and gravity to discharge inside reactor feed liquid, after collection, analyze.But which is applied in the high solid concentration anaerobic fermentation system that TS >=8% is even higher, has following drawback: 1. the liquid of collection is many, solid is few, can not react the True composition of sampling layer; 2. valve (conventional have butterfly valve and gate valve) is very easy to corrosion, thereby makes operation easier become large, even cannot sample, and the valve after corrosion easily causes poor sealing; 3. high solid concentration material, at ducted poor fluidity, easily forms and persists, and possibility blocking pipe; 4. wayward sampling amount.Therefore, research and develop and a kind ofly can reflect that the true feed liquid of sampling responding layer forms, and good airproof performance, be difficult for corrosion, sampling method and device easy and simple to handle, that be easy to control sampling amount just become the key of dealing with problems.
Summary of the invention
