Description

Technical Field

[0001] The present invention relates to the efficient treatment of discarded cigarette butts, and in particular to an intelligent pyrolysis method, device, computer equipment and readable storage medium for discarded cigarette butts. Background Art

[0002] Ethyl triacetate is usually produced chemically by esterification of glycerol and acetic acid in the presence of a catalyst (such as sulfuric acid), which consumes a large amount of chemical substances and produces a large amount of waste and toxic residues. However, the method of mixing ethyl triacetate with biodiesel for combustion has appropriate environmental performance, helps to reduce air pollution, and improves the flammability of biodiesel. It has more stringent requirements for the decomposition environment and is affected by different environmental factors such as temperature, humidity, and pH value. Therefore, it is necessary to find an alternative and environmentally friendly source of ethyl triacetate. Ethyl triacetate can be separated from cigarette butts, and more environmentally friendly ethyl triacetate can be obtained by this separation, and mixed with biodiesel to improve the efficiency of biodiesel.

[0034] To simulate this behavior, random positions are generated near each raccoon's position based on the following formula:

[0035]

[0036] If the updated operating efficiency is better, update the current operating efficiency, otherwise keep it as it is:

[0039] (2.5) Determine whether the termination condition is met. If not, return to step (2.3); if so, output the optimal operating efficiency.

[0040] Furthermore, an improvement is proposed to the raccoon optimization algorithm, and step (2.3) is improved by introducing a spiral search strategy to improve the global search capability. The improved formula is as follows:
