Abstract
With the gas produced in anaeroic digestor for an internally-powered, realize a kind of device of air pressure type automatic intermittent circulation.It by plenum chamber 11, water lev el control air valve 6, gas skirt 12, air inlet (water) pipe 3, return line 5, reverse checkvalve 14, enter into bottom digestion zone 13 and jointly form circulation loop.When closing water lev el control air valve 6, biogas is through sealing gland 4, gas skirt 12, through air inlet (water) pipe 3, constantly enter in plenum chamber 11, pressure in plenum chamber 11 is constantly increased, forces the feed liquid in plenum chamber 11 through return line 5, reverse checkvalve 14, enter into bottom digestion zone 13.When plenum chamber 11 water level low to designated water level time, water lev el control air valve 6 is opened automatically, in plenum chamber, gas is constantly discharged, when the water level in plenum chamber 11 is to setting low-water level, water lev el control air valve 6 is opened automatically, and plenum chamber 11 pressure reduces, the water on top, digestion zone is through air inlet water pipe 3, be inhaled in plenum chamber, during to setting high-water, water lev el control purging valve 6 is automatically switched off.Circulator enters next round draining, the circulation of venting, water suction, thus achieves the circulation of internally-powered automatic intermittent.
Description
Art
The utility model is related to organism and under anaerobic generates inflammable gas through anaerobic digestion, and a kind of device providing internally-powered air pressure type automatic intermittent to circulate for anaeroic digestor.
Background technology
At present, anaeroic digestor to all be used to carry out digestion process in the production of bioenergy, municipal wastes, the many-side such as sewage disposal and aquaculture night soil-treatment.Carry out suitable circulation, stir being the effective way improving anaeroic digestor usefulness to feed liquid in anaerobic digestion process.Existing digestive organ can be divided into from circulation, stirring outer power cycle, stirring and external power-free circulation, stir two classes.The shortcoming of external power-free circulation, stirring digestive organ: digestive organ is bulky, and initial cost is high, takes up an area wide, production cycle is long, and efficiency is low, separately has the shortcoming of IC internally-powered circulation digestive organ: be not suitable for the feed liquid that suspension content is higher, be unfavorable for insulation, inapplicable small business.Have outer power cycle to stir the shortcoming of digestive organ: the investment of motor, water pump is large, productive power and maintenance cost high, comprehensive benefit is poor.For the most efficient fluidized-bed and expanded bed, because needing to carry out feed liquid circulation with driven by motor water pump in production process, making production energy consumption too high and cannot use in actual production.With reference to " biogas practical technique ".
Summary of the invention
In order to overcome the above shortcoming of anaeroic digestor, the utility model provides a kind of gaseous tension produced with anaeroic digestor self for power, realizes a kind of device of internally-powered air pressure type automatic intermittent circulation.
The technical scheme that the utility model solves internally-powered air pressure type automatic intermittent circulator is: in anaeroic digestor, by sealing gland, gas skirt, inlet pipe, plenum chamber, digestive organ is divided into the digestion race way of middle and lower part and the precipitation recirculating zone of middle and upper part.Constantly entered in plenum chamber through inlet pipe by sealing gland, gas skirt when the methane gas in digestion zone constantly produces.At this moment water lev el control air valve is in closing condition, and in plenum chamber, gas constantly increases generation pressure, and the feed liquid in former plenum chamber is constantly pressed into return line through reverse checkvalve, the bottom entering into digestion zone by gas.When the feed liquid in plenum chamber is forced into setting low-water level, water lev el control air valve is opened automatically, gas in plenum chamber is constantly discharged, at this moment the feed liquid on top, digestion zone is constantly inhaled in plenum chamber through inlet pipe, when the material liquid level in plenum chamber reaches set(ting)value, water lev el control air valve is closed, and circulator enters again air inlet, the draining of next round, the working cycle of venting, water suction.
The beneficial effects of the utility model are: reduce the construction of anaeroic digestor, production and maintenance cost, reduce the power consumption in production process.The digestive organ of circulation, agitator is not installed, can greatly improves its productive efficiency after repacking, shorten the production cycle.This circulator is applicable to the circulation of multiple feed liquid, and its internal circulating load is equal to the gas production rate of digestion zone.The manually adjustment of adjusting air valve, can control digestive organ internal circulating load.Inlet pipe is suitable for reading apart from plenum chamber top 10-20 centimetre, is formed and impacts, be conducive to precipitation that is degassed and suspended substance during water inlet.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1. without plenum chamber, 2. precipitate recirculating zone, 3. inlet pipe, 4. sealing gland, 5. return line, 6. water lev el control air valve, 7. manual regulation air valve, 8. air outlet with no pressure, 9. overflow port, 10. have plenum chamber, 11. plenum chambers, 12. gas skirts, 13. digestion zones, 14. reverse checkvalves, 15. feed-pipes.
Embodiment
In the drawings, digestion zone 13 constantly produces biogas, biogas constantly enters in plenum chamber 11 through sealing gland 4 and gas skirt 11 through inlet pipe 3, at this moment the water lev el control air valve 6 being arranged on plenum chamber 11 top is in closing condition, pressure in plenum chamber 11 constantly increases forces feed liquid through being arranged on the return line 5 bottom plenum chamber 11, reverse checkvalve 14 is constantly pressed into the bottom of digestion zone 13 by gas, when the water level in plenum chamber 11 is pressed onto setting low-water level by gas, water lev el control air valve 6 is opened automatically, gas in plenum chamber 11 is constantly discharged, because precipitating the water level of recirculating zone 2 higher than plenum chamber 11, at this moment the feed liquid on top, digestion zone 13 can constantly be inhaled in plenum chamber 11, when water level height is to set(ting)value, water lev el control air valve 6 can be automatically switched off, circulator completes and once circulates.Circulator enters air inlet, the draining of next round simultaneously, the working cycle of venting, water suction.
In a word, the utility model provides a kind of internally-powered air pressure type automatic intermittent circulator, the above.Be only a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.
