Direct-absorption anaerobic reactors can maintain the fermentation process of microorganisms by utilizing solar absorption and scattering media in the biogas reactor to improve the slurry temperature. Direct-absorption heating alone can save the corresponding electric energy and ensure the normal fermentation process of the biogas slurry in the reactor, but there is still the problem of temperature fluctuation. In order to improve the stability of the fermentation process, it is proposed to optimize the design of this kind of reactor by adding paraffin phase change material. This article mainly studies the influence of paraffin phase change material added on the top and side of the reactor in the fermentation process and gives the corresponding design parameters for different climatic conditions, which lays a theoretical reference for the design process of this kind of reactor.
直接吸收厌氧反应器可以利用沼气反应器中的太阳吸收和散射介质来维持微生物的发酵过程，从而提高浆料温度。单独的直接吸收加热可以节省相应的电能，并确保反应器中沼气浆的正常发酵过程，但仍存在温度波动的问题。为了提高发酵过程的稳定性，提出通过添加石蜡相变材料来优化这种反应器的设计。本文主要研究了在发酵过程中在反应器的顶部和侧面添加石蜡相变材料对其的影响，并给出了针对不同气候条件的相应设计参数，为这种反应器的设计过程奠定了理论参考。
