Embodiment 1

[0027] Embodiment 1 (basic embodiment)

[0028] The invention is a solar biogas slurry evaporation and concentration device, the device includes: a heat collecting plate, a transparent cover plate, a distiller shell, a distillation chamber, a distillate collection tank, a heat storage material, a thermal insulation material layer, and a distillate recovery pool , Concentrate recovery tank, fan and inverted trapezoidal support. The heat collecting plates are placed inside the still shell. Water baffles are placed on the edge of each heat collector plate 1, and the length of the water baffles is equal to the length of the heat collectors so that the biogas slurry flows in a straight line (see Figure 4 ), or the length of the water baffle is less than the length of the collector plate and they are arranged in a staggered manner (see Figure 6 ), so that the biogas slurry is S-flow. The transparent cover plate is placed on the top of the distiller shell, and an airtight distill...

Description

technical field [0001] The invention belongs to the technical field of rural renewable energy utilization and is related to the field of concentration and utilization of biogas slurry. In particular, the invention relates to a solar energy biogas slurry evaporation and concentration device. Background technique [0002] The output of agricultural waste in China's rural areas is increasing year by year, and the characteristics of biogas projects in agricultural waste reduction, recycling, and harmlessness have attracted more and more people's attention and developed rapidly. However, biogas projects will produce a large amount of biogas slurry while producing biogas. Due to the large amount of biogas slurry produced and the low nutrient concentration, it has caused great difficulties in its treatment and utilization, and has become a bottleneck restricting the development of the biogas industry. Therefore, the concentration and reduction of biogas slurry is a way of resource ...
