ADVANTAGE - The device has the scientific, reasonable and the practical value.    DETAILED DESCRIPTION - Dry-type anaerobic fermentation device, comprises a horizontal fermentation device, a stirring device, a forcible charging device, a heat exchanging device, a temperature-measuring device, a temperature-controlling and temperature-keeping device, a control device, a biogas slurry reflowing spray device and a pH meter, an oxidation reduction electric potential and water content monitoring device. The horizontal fermentation device comprises an inlet, an outlet and a stirring device longitudinally passing through the whole tank body. The stirring device is an electric stirring device connected with multiple stirring arms; and is electrically connected with the control device. The material inlet is at the inlet of the horizontal fermentation device. The forcible charging device is at the material inlet, and the forcible charging device and the control device are electrically connected. The heat exchanging device is present on the horizontal fermentation device and is connected with the temperature-controlling and temperature-keeping device through a pipeline by passing through the control valve and the circulation pump to form a circulation heat exchanging system. The temperature-measuring device is fixed in the horizontal fermentation device and is electrically connected with the control device. The control device is electrically connected with the control valve and the circulation pump. The biogas slurry reflowing spray device and the temperature-controlling and temperature-keeping device are on the outer wall of the horizontal fermentation device. The pH meter, the oxidation reduction electric potential and the water content monitoring device is fixed in the horizontal fermentation device through a probe. An INDEPENDENT CLAIM is also included for the dry-type anaerobic fermentation comprising: (a) putting organic waste into a special anaerobic fermentation device; fermenting at the optimal temperature of 55-60 degrees C throughout the process; (b) generating marsh gas and residue of high concentration after 15-30 days; (c) converting the marsh gas generated into an electric energy and heat energy; purifying into natural gas, as an automobile fuel or conveying to a natural gas pipe network; and (d) preparing organic fertilizer by using the residue generated in the step (b), and using the organic fertilizer to develop ecological agriculture.
