Abstract
The invention provides a dry-wet combined anerobic fermentation reactor. The reactor comprises a wet fermentation reactor and a dry fermentation reactor and also comprises a buffer tank, wherein the charging opening of the buffer tank is connected with the discharging opening of the wet fermentation reactor and the discharging opening of the dry fermentation reactor respectively, and the discharging opening of the buffer tank is connected with the charging opening of the dry fermentation reactor. The reactor fully combines advantages of the wet fermentation technology which has good mass transfer effect and the dry fermentation technology in which the fermentation residue has low moisture, and the two phase anaerobic gas production effect is good; moreover, the feeding problem of the dry fermentation reactor is effectively solved.
Description
Technical field
The present invention relates to a kind of dry wet anaerobic fermentation reactor that can the various wastes of comprehensive treating process, belong to field of Environment Protection.
Technical background
Wet type zymotechnique and technical equipment be comparative maturity at present; but utilize the biological flue gas engineering project that this technique is built in operational process, easily to produce a large amount of natural pond liquid; incompatible with fermentation raw material kind and the practical situation such as form, mode of agriculture and ideology level that China is current; be unfavorable for environment protection and saving water resource; and in biological flue gas engineering project operational process, consume a large amount of fermentation raw materials required energy that heats up, become the bottleneck problem of restriction biological flue gas engineering development.For solving the series of problems of wet type fermentation, the research of dry anaerobic fermentation process becomes hot subject.By the end of at present, the control problem of the turnover of dry anaerobic fermentation process raw material anaerobic reactor, system mass transfer and redox potential is difficult point wherein, and these solutions are never good, and dry wet anaerobic ferment process heavy industrialization application faces no small difficulty.
Summary of the invention
The object of this invention is to provide a kind of dry wet anaerobic fermentation reactor that can the various wastes of comprehensive treating process, efficiently solve the charging problem of dry type fermentation reactor.
A kind of dry wet anaerobic fermentation reactor of the present invention, comprise wet type fermentation reactor and dry type fermentation reactor, also comprise surge tank, the opening for feed of described surge tank is connected with the discharge port of wet type fermentation reactor and the discharge port of dry type fermentation reactor respectively, and the discharge port of described surge tank is connected with the opening for feed of dry type fermentation reactor.
Further, a kind of dry wet anaerobic fermentation reactor of the present invention, also comprises ram pump, and the opening for feed of described ram pump is connected with the discharge port of surge tank, and the discharge port of described ram pump is connected with the opening for feed of dry type fermentation reactor.
Further, in described surge tank, thermal source is set.
Further, described dry type fermentation reactor is vertical dry type fermentation reactor, and thermal source is set in reactor.
The beneficial effect that the present invention produces is, dry wet anaerobic fermentation reactor of the present invention, the natural pond liquid that utilizes wet type zymotechnique to produce improves the physical condition of dry type fermentation raw material and system, improve the mass transfer effect of dry type fermentation system, this technique not only can realize dry wet associating, also can utilize dry material to possess be easily the hydrolyzed feature of acidifying of double oxygen condition, realize diphasic anaerobic, to be fully good in conjunction with wet type zymotechnique mass transfer effect, the advantage that dry type fermentation process fermentation resistates water content is low and diphasic anaerobic aerogenesis is effective, break through technology and popularization bottleneck that traditional biological gas works faces.
Embodiment
A kind of dry wet anaerobic fermentation reactor of the present invention, comprises wet type fermentation reactor and dry type fermentation reactor, is preferably vertical dry type fermentation reactor, in its dry type fermentation reactor, thermal source is set; Also comprise surge tank, be also provided with thermal source in described surge tank, the opening for feed of described surge tank is connected with the discharge port of wet type fermentation reactor and the discharge port of dry type fermentation reactor respectively, and the discharge port of described surge tank is connected with the opening for feed of dry type fermentation reactor.
The mobility resistates that ferments is preferably housed in described surge tank, and this mobility resistates that ferments preferably can come from wet type fermentation reactor, also can come from the bottom discharge of dry type fermentation reactor.When the feed system of dry type fermentation reactor causes charging not smooth because of feed states problem, utilize the lower concentration material in surge tank to regulate fermentation raw material, finally realize smooth charging, solved the charging problem in dry type fermentation system.
Further, a kind of dry wet anaerobic fermentation reactor of the present invention, also comprises ram pump, and the opening for feed of described ram pump is connected with the discharge port of surge tank, and the discharge port of described ram pump is connected with the opening for feed of dry type fermentation reactor.
By ram pump, the resistates that ferments preferably of mobility in surge tank is injected from fermentor tank top, improved on the one hand the contact effect of fermentation materials with active flora; Utilize on the other hand impulse force that tank endosome tying shell structure is destroyed, thereby improve mass transfer effect, saved whipping appts; Can also fully contact with carrying out the feed liquid that meets temperature requirement of self-wetted fermentation system in surge tank on the other hand, solve the problems such as dry type fermentation system non-uniform temperature.
