Description

Changing food waste or organic waste are produced the equipment of engine gas
Technical field
The utility model relates to the equipment of producing engine gas with changing food waste or organic waste, belongs to a kind of chemical industry equipment.
Background technology
Continuous improvement along with people's daily life, the amount of changing food waste and organic waste is more and more many, utilize and managed changing food waste and organic waste cheaply, make that it is innoxious, minimizing and resource utilization, stop changing food waste and enter the forage plants chain, safeguard that people's food sanitation with healthy, is the major issue of current social concerns, great environment social effect is arranged.
Relevant changing food waste is the existing many reports of the method for raw material production biogas; In CN101134684B, " a kind of method of changing food waste diphasic anaerobic fermentation producing hydrogen and methane " disclosed, first mutually in the fermentation generation concentration of hydrogen be more than 50%, second mutually in the fermentation generation concentration of methane be to the maximum more than 60%, have the low defective of fermentation gas product calorific value; Nature can biochemical fermentation raw material mainly be carbohydrate such as starch, protein, Mierocrystalline cellulose and hemicellulose, as changing food waste, cities and towns organic waste, crop material, wood chip, rice husk, organic sewage, poultry manure, mud etc.; According to the biochemical reaction principle, it is the anaerobically fermenting that carries out under secluding air (or oxygen) environment that methane is produced in fermentation, and anaerobically fermenting mainly comprises the acidication stage, produces three stages such as hydrogen product acetic acid stage and product methane phase; Produce in two stages of acetic acid at acidication and product hydrogen, comprising a large amount of hydrogen in the fermentation gas that fermentation equipment discharges is necessary process, in the collected final mixed gas product of whole anaerobic biological treating processes, except containing a large amount of methane gass, also be mixed with a certain amount of hydrogen, the mixture that belongs to hydrogen and methane gas causes the methane production of whole fermentation system to reduce; According to the biochemical reaction principle, hydrolysis bacterium and product hydrogen produce acetic bacteria has good activity at pH value 5-6.5, can accelerate to produce the process of hydrogen and acetic acid reaction, and methanobacteria is suppressed when pH value 5-6.5, and non-activity does not produce methane; Methanobacteria is that the environment of 6.8-7.5 has good active at PH, produces methane; Therefore, be the acidication of 5-6.5 and produce hydrogen and produce acetic acid in the stage that the decomposition gas that fermentation is collected mainly is to be the mixed gas that amounts of carbon dioxide is combined into of advocating peace by hydrogen component at PH; So conventional changing food waste is or/and contain a large amount of low-calorie hydrogen (H in the biogas that the organic waste Unareobic fermentation is produced 2, 10798KJ/m 3, under the standard state); 07 month 01 day calendar year 2001, China issued and implemented the national standard of GB18047-2000 compressed natural gas used as vehicle fuel, and regulation combustion gas gross calorific value must be greater than 31.4MJ/m in this standard 3(or 31400KJ/m 3Under the standard state), to carbonic acid gas (CO 2), sulfur oxide (SO 2), hydrogen sulfide (H 2S) and other acidic substance (as NO 2, HCl) the strictness control of trace and moisture-free arranged; Therefore, Chang Gui changing food waste is or/and contain a large amount of low-calorie hydrogen (H in the biogas that the organic waste Unareobic fermentation is produced 2, 10798KJ/m 3, under the standard state) and carbonic acid gas and other obnoxious flavour, its calorific value is low, generally at 20-25MJ/m 3Under the standard state, the ingredient components complexity, impurity is many, can not satisfy the demanded fuel of engine (or oil engine), can not be used as motor spirit; Usually, this low-calorie combustion gas mainly is used as generator factory.Thermal source, and the heat supply and the air feed that are used for industry or resident living;
Especially, oxidation operation is not thorough in the anaerobic digestion metabolism, also must be through under the condition of fully oxygen supply, carrying out aerobic fermentation, make good use of the vital movement process of oxygen animalcule and aerobic-anaerobic microbe, the remaining organic pollutant of anaerobically fermenting further is oxidized to than the stable inorganic thing by the aerobic fermentation biological process, finally, organic waste is thoroughly decomposed, really accomplish changing food waste or/and the harmless treatment of organic waste.Include a large amount of starch (as residue rice), protein (as residual meat fish), grease (edible oil) and Mierocrystalline cellulose carbohydrate such as (as the residual leaves of vegetables) in the changing food waste, complicated component, in the methane gas that fermentation is produced, contain a large amount of nitrogenous (N), sulphur (S), carbonic acid gas and organic macromolecule impurity, must make with extra care methane gas, to satisfy the quality standard requirement of engine gas.
Up to the present, at China and world patent document databse, relevant aspects such as books, publication, magazine and suitability for industrialized production application, also do not find and utilize changing food waste to be raw material, the equipment of the car and boat engine gas of high heating value is produced in the biochemical fermentation processing;
The purpose of this utility model is exactly defective and the deficiency that will overcome and remedy prior art, thereby providing a kind of collects the hydrogen that produces in acidication stage and the product hydrogen product acetic acid stage fermentation and lay in, then hydrogen is fed in the fermentation equipment of producing methane phase, under the effect of methanobacteria, convert methane to, to improve the transformation efficiency of methane gas; Further the acidic substance in the methane gas or organic macromolecule impurity are decomposed and make with extra care, allocate, compress, utilize biochemical switch technology, produce the equipment of vehicular engine (or oil engine) combustion gas of high heating value.
