Abstract

The invention relates to a biomass fermentation reaction device, which consists of a fermentation reactor, a liquid adding pipeline, a heating device, a stirring device, a temperature measuring device, a moisture measuring device and a support frame, wherein the fermentation reactor comprises an upper layer fermentation reactor and a lower layer fermentation reactor, and the fermentation reactor is in a rectangular box type structure and is fixed on the support frame in an overlapped type. The reaction device is used for carrying out the biomass fermentation reaction by adopting a method of adding bacterium liquid and adopting a two-step fermentation method. The reaction device has the characteristics that the energy consumption is low, the cost is low, the operation is easy, and safety and reliability are realized. The sufficient turning of materials can be realized under the regular reciprocating stirring of the stirring device, and the aerobic goal is reached. Through the precise thermocouple temperature control and the combination with the solar technology, the energy consumption is greatly saved. Through the design of the double-layer reactor, the material processing capability is improved, simultaneously, the materials are respectively positioned in the upper layer reactor and the lower layer reactor according to the characteristics of different stages of the reaction, the respective treatment of reactants is realized, and the fermentation efficiency is improved.

Description

[0001] technical field [0002] The invention relates to microbial fermentation technology, in particular to a biomass fermentation reaction device and its application. Background technique [0003] With the advancement of agricultural science and technology, the output of agricultural products has increased significantly. In addition, with the improvement of people's living standards, the rate of urban greening has also continued to increase. Therefore, more and more agricultural waste and landscaping waste are produced. These wastes are not only related to People compete for land, and at the same time affect the image of the city. In order to solve this problem, landfill and incineration have become conventional means of disposal. Because the waste contains a large amount of biomass waste, it degrades slowly during the landfill process. In addition, leachate and biogas will be produced after its corruption and acidification, which not only pollutes surface water and groun...
