Description
Technical field
The present invention relates to biomass energy device technique field, particularly a kind of pretreatment device for multi-element material.
Background technology
Biological flue gas is accounting for important role in people life and industrial production, combustion gas is the general name of gaseous fuel, and its releases heat that can burn, for resident and industrial enterprise.Part of fuel gas can utilize fermenting raw materials manually to make, and for example uses agricultural crop straw or feces of livestock and poultry, but no matter is agricultural crop straw class or feces of livestock and poultry, all will carry out pretreatment before being prepared gas, and this just relates to raw material preprocessing device.
For now, because the physicochemical property of different material is different, the pretreatment mode difference is also larger, and to feces of livestock and poultry, the general allotment stirring pool that adopts is combined with pump; , to the agricultural crop straw class, take side grass machine, beater grinder, stirring pool to be combined with pump.These two kinds of raw materials are the pretreatment unit of oriented correspondence all, but these two kinds of pretreatment units corresponding to material have the defect that can't make up, agricultural crop straw class raw material preprocessing device can only carry out pretreatment for stalk, the feces of livestock and poultry raw material preprocessing device is also same reason, this just to being prepared with of biological flue gas very large restriction, same biological fuel gas engineering can only be invested the different pretreatment system of several covers, perhaps can't use multi-element material.In addition, all produce a large amount of house refuses every day in our life, its total amount is the amount of feces of livestock and poultry and agricultural crop straw head and shoulders above, but with regard to the fragmentation of current techniques to house refuse, other processing of farm products discarded objects, the application in biogas engineering is almost also blank.This makes the annual a large amount of organic wastes that produce of China to be utilized effectively, and is innoxious lower with the resource rate, and the seasonal shortage of raw material, fluctuation of service appear in the biological fuel gas engineering.
And agricultural crop straw class pretreatment equipment, comprise hay cutter, beater grinder etc., these devices are open high-speed impact structure, during work, speed is generally more than 3000rpm, power consumption is large, the noise on-site measurement that vibration causes surpasses 85dBa, and the material after pulverizing disperses, and dust pollution is serious.Country's Eleventh Five-Year Plan science and technology supporting project encourages the related scientific research institutes to carry out correlation technique research, but lacks at present effectively progress and application achievements.
Need to monitor pH value in zymotechnique while preparing biological flue gas, generally by regulating dry substance concentration and inlet amount, control.Due to the sweat hysteresis quality, the fermentation reactor volume is far longer than inlet amount simultaneously,, by this rear regulative mode, often causes the sweat fluctuation large, and microbe groups and quantity also can't be grasped, and gas producing efficiency is low and unstable.
Therefore, a kind of pretreatment device for multi-element material is provided, realization can be carried out pretreatment to plurality of raw materials simultaneously, and carry out the raw material nutrition deployment, improve the adaptability of biological fuel gas engineering to raw material to reach, improve simultaneously fermentation gas rate and stability, become those skilled in the art's problem demanding prompt solution.
