Abstract

The invention relates to a fermentation reactor integrating functions of stirring and crusting breaking and a stirring crust-breaking method, and the problems in the prior art are solved that an anaerobic reactor is low in gas production rate and low in gas productivity during fermentation. The fermentation reactor comprises a digester, a heat tracing band, a heat-insulation layer and a protective layer; the fermentation reactor also comprises a digester upper cover, a first stirrer with a frequency converter, a charge level indicator, a second stirrer with a frequency converter and a third stirrer with a frequency converter; the digester upper cover is buckled on the digester; the protective layer, the outer side wall of the digester is successively sleeved by the heat-insulation layer and the heat tracing band from outside to inside; the inner side wall of the digester is provided with a feed inlet; and the first stirrer with the frequency converter and the third stirrer with the frequency converter are disposed on the digester; the second stirrer with the frequency converter is disposed on the bottom inner wall of the digester. The fermentation reactor integrating the functions of stirring and crusting breaking is applied to the field of full-mixing anaerobic fermentation.

Description

technical field [0001] The invention relates to a fermentation reactor integrated with stirring and shell breaking and a stirring shell breaking method. Background technique [0002] In the fully mixed anaerobic fermentation reactor that uses high-fiber materials such as cow dung and straw as raw materials, due to the interaction between microorganisms and crude fiber materials in the upper part of the fermentation feed liquid in the reactor, it is easy to form a scum layer, harden the crust, If it is not solved in time, the gas production rate of biogas will be reduced, seriously affecting the normal operation of the anaerobic reactor, and the uneven mixing of raw materials in the fermentation reactor will lead to low gas production performance. Contents of the invention [0003] In order to solve the problems of lower gas production rate and low gas production performance during fermentation in an anaerobic reactor in the prior art, the present invention further provides...
