Abstract

The invention discloses an accelerant as well as application and a preparation device thereof. The accelerant is prepared from the following components in parts by weight: 50 to 90 parts of biogas slurry, 5 to 40 parts of cow dung, 2 to 4.5 parts of enzyme and 0.5 to 5 parts of crop straw. The accelerant is applied to fermentation of crop straws, and the weight of the accelerant added during application accounts for 5-35% of the total weight of the crop straws and the accelerant. The preparation device of the accelerant comprises a hydrolysis tank, a heating coil and an aeration mechanism. A stirring mechanism is arranged in the hydrolysis tank and is suitable for stirring materials in the hydrolysis tank; the heating coil is annularly arranged along the side wall of the hydrolysis tank; the aeration mechanism is arranged in the hydrolysis tank and is suitable for inputting gas into the hydrolysis tank. According to the accelerant, the fermentation degradation time of the crop straw is greatly shortened, the gas production rate is greatly increased, the energy consumption of the fermentation degradation of the crop straw is greatly reduced, and the operation cost is saved.

Description

technical field [0001] The invention relates to the technical field of crop straw fermentation, in particular to an accelerator and an application and preparation device thereof. Background technique [0002] my country is a country with a large output of agricultural waste. According to statistics, the total annual output of crop straw is more than 700 million 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 will increase at a rate of 6%. If these crop straws are not disposed of in time, they will not only pollute the environment, but also cause waste of resources. [0003] Biogas is a mixed gas produced by microbial fermentation of organic matter under anaerobic conditions; it is a combustible gas with high calorific value, and is a good biomass clean energy. Crop straw is a common fermentation raw material in biogas engineering. Conventional anaerobic fermentation o...
