This invention discloses a harmless treatment device for livestock and poultry breeding waste, belonging to the field of anaerobic treatment technology. To address the problem of biogas suffocation during biogas digester use, leading to a significant reduction in effective gas production and affecting digester safety, as well as poor gas-liquid separation during gas collection and severe liquid contamination in biogas, resulting in low pure gas capture rates, the invention includes a biogas digester body and an inlet connected to one side of the digester body. A skylight cover is fixed to the upper center of the digester body, and ventilation ports are provided on both sides of the bottom surface of the skylight cover. This invention enables the collection and circulation of biogas from within the liquid. Combined with the ventilation ports and guide pipes, it collects and circulates the naturally rising biogas within the digester body, improving biogas collection efficiency while preventing scum and foam from covering the gas-liquid interface, thus avoiding suffocation of biogas and affecting biogas collection efficiency and pressure safety within the digester body.

The invention relates to the technical field of garbage storage and fermentation, in particular to a garbage storage and fermentation device with conveying and preheating functions. Garbage is output through a conveying device, a preheating cavity formed in a shell is used for being communicated with a heat source, the conveyed garbage is preheated by supplying heat to the preheating cavity, and after preheating is completed, the garbage is conveyed to the shell; the garbage is conveyed into the fermentation cavity of the fermentation tower for storage fermentation, in the fermentation process, generated heat is collected and serves as a heat source, energy consumption is reduced, the fermented garbage is pressurized through the power device, water generated by fermentation is discharged, and it is avoided that in the subsequent combustion process, the heat value is reduced, and after fermentation is completed, the garbage is discharged out of the fermentation cavity through the discharging device; and generated water is mixed with other liquid media to be fed into the preheating cavity, so that the energy utilization rate is increased.

The invention relates to a chemical coal blending method and device and computer equipment. The method comprises the following steps: acquiring spectral data of a to-be-distributed coal flow, and performing batch segmentation processing and regression processing on the spectral data to obtain a batch quality vector of the to-be-distributed coal flow; determining a batch quality code of the batch quality vector according to the hearth tolerance envelope; determining a reference time frame, and constructing a time sequence topological graph based on the reference time frame; determining a target cross-layer edge set pointing to a hearth node in the time sequence topological graph, determining a root node state of the search tree based on the target cross-layer edge set, and performing mixed integer tree search in combination with a priority bit of batch quality coding to obtain a candidate scheme set; performing index evaluation and risk priority ranking on candidate schemes in the candidate scheme set to obtain an ordered feasible solution list; and analyzing the first feasible scheme in the ordered feasible solution list into an equipment readable instruction, and carrying out coal flow scheduling according to the equipment readable instruction. According to the invention, a coal blending scheme capable of meeting various requirements can be provided.
