Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] See attached figure 1 , attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5, the present invention includes a horizontal fermenter 10 that can rotate along its axis. The fermenter 10 is tilted under the action of the support ring 9, and can rotate itself under the drive of the motor. The biogas slurry return spraying system fixed on the ground, one end of the fermenter 10 is the feed end, and the other end is the discharge ...

Abstract

The invention provides a continuous horizontal dry-process anaerobic fermentation system, belonging to the technical field of fermentation plants. The continuous horizontal dry-process anaerobic fermentation system comprises a horizontal fermentation tank capable of rotating along the axis, wherein a biogas slurry reflux spray system is fixedly arranged in the fermentation tank; one end of the fermentation tank is a feed end, and the other end is a discharge end; the height of the feed end is greater than that of the discharge end; the feed end is connected with a mixing bin through a feed system; the feed end is provided with a biogas pipe; the discharge end is provided with a fermentation leftover discharge system; and a temperature measuring device is arranged inside the fermentation tank. Both ends of the obliquely-arranged horizontal fermentation tank are respectively connected with the automatic feed system and automatic discharge system, and the reflux spray system is arranged in the fermentation tank, thereby implementing continuous stable feed and discharge; and thus, the biogas slurry can implement circulating spray, and the marsh slag can implement circulating mixing. The continuous horizontal dry-process anaerobic fermentation system has the advantages of simple structure, reasonable design, high operation smoothness and low energy consumption, and can implement full-automatic control. The capacity aerogenesis rate is 1.0-1.5 m<3> / m<3>.d.

Description

technical field [0001] The invention belongs to the technical field of fermentation equipment, in particular to a continuous horizontal dry anaerobic fermentation system. Background technique [0002] my country is a country with a large amount of agricultural waste output. According to statistics, the annual discharge of livestock and poultry manure is about 4 billion tons, of which about 3 billion tons of manure from intensive farms, and an annual growth rate of 10%; more than 700 million crop straw tons, with the continuous increase of my country's population, the grain output increases year by year, and the corresponding annual total output of straw increases at a rate of 6%. If these organic wastes are not disposed of in time, they will not only pollute the environment, but also cause waste of resources. [0003] In the treatment process of organic waste, dry anaerobic fermentation subverts the traditional method of wet anaerobic fermentation that must completely mix ra...
