Embodiment Construction

[0033] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0034] Such as image 3 As shown, the anaerobic fermentation tank 6 of this embodiment includes a tank body 61 , eight agitators 5 and a liquid blocking device 66 . The tank body 61 has an axis 62 . Each stirrer 5 is fixedly connected to a connection area of ​​the inner wall of the tank body 61 through its rotating shaft 50 . The liquid blocking device 66 includes at least one slope surface, and the slope surfaces are used to block and bounce fluid directed thereto.

[0035] Such as image 3 As shown, the projection of the axis of each rotating shaft 50 in the plane formed by the normal 63 of its connecting area and the axis 62 is the first projection line 501 . The included angle between the first projection line 501 and the normal 63 is α, and the value of α ranges from 20° to 70°,...

Abstract

The invention discloses an anaerobic fermentation tank which comprises a tank body and a plurality of stirrers; each stirrer comprises a rotary shaft and a stirring impeller which is arranged on one end of the rotary shaft; the other end of each rotary shaft is fixedly connected with a connecting area on the inner wall surface of the tank body; and the axis of each rotary shaft forms an angle with the normal of the connecting area. According to the anaerobic fermentation tank, because each rotary shaft forms the angle with the normal of the connecting area which is fixedly connected with the rotary shaft, fermentation liquor is in rolling combination along the axial direction of the tank body and / or in the rolling combination along the radial direction of the tank body, so that the uniformity in the distribution of solid raw materials in the fermentation liquor is greatly improved.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to an anaerobic fermentation tank. Background technique [0002] Bioenergy chemical industry is a key development industry in the 21st century. The volume of its core equipment, anaerobic fermentation tank, is getting larger and larger. At present, the volume of a single fermentation tank in my country has reached 3,500 cubic meters. For such a large volume of anaerobic fermentation tank, how to Doing a good job in system design and reducing energy consumption has become an urgent issue to be solved. [0003] The function of the anaerobic fermentation tank is to provide excellent conditions for the growth of microorganisms in order to meet the growth and reproduction of microorganisms. In anaerobic fermenters, these organisms perform their catalytic or metabolic functions and produce reactants and metabolites that are difficult to obtain with conventional chemical reactions. ...
