Problems solved by technology

The former is a drying system that uses solar energy supplemented by other heating methods such as electric energy as the drying heat source. Its disadvantages are: high equipment cost and high energy consumption when treating sludge
The equipment uses heat transfer oil as a heat transfer medium to transfer heat to the hollow heat shaft, and then heat the sludge through the hollow heat shaft. Due to the excessive number of transfers in the heat transfer process, the heat loss rate is too large, and the amount of heat transfer oil used It will lead to higher cost, and the leakage of heat transfer oil will easily lead to environmental pollution

Description

technical field [0001] The invention relates to a sludge and excrement fermentation and drying system, in particular to a solar air heat collection sludge and excrement fermentation and drying system, which belongs to the technical field of sludge and excrement drying. Background technique [0002] The existing solar sludge and feces fermentation and drying systems are mainly of the following two types: 1. Solar mixed sludge drying and fermentation system, 2. Solar sludge drying and fermentation system. The former is a drying system that uses solar energy supplemented by other heating methods such as electric energy as the drying heat source. Its disadvantages are: high equipment cost and high energy consumption during sludge treatment. The latter is a drying system that only uses solar energy as the drying heat source to heat the sludge. The disadvantage is that the drying speed is slow and it is greatly affected by the climate. In order to overcome the shortcomings of the...
