Abstract
Purpose. In the light of the urgency of improving energy saving of the technological processes of solid waste management in Ukraine, the purpose of the work is modernization of equipment for secondary raw materials processing. Methodology. A review and comparative analysis of the modern level of technical support of crushing processes in the sphere of waste management have been conducted. Originality. Taking into account the main requirements of the branch-specific regulatory legal acts, principles and planned activities of the National Waste Management Strategy, as well as analysis of the shortcomings of the special equipment already known, a principally new design of a Crushing Unit with Gravity-Pneumatic Actuator for using alternative energy resources during the operation of the necessary technological equipment of secondary raw materials management systems has been proposed. Practical value. The scheme of the reference apparatus we have developed relates to devices for crushing with rotating knives driven by volumetric displacement power plants, can be used in systems while creating a significant amount of solid fractions of waste of a high bulk density, enables generation and accumulation of electric energy required for its work, in which it uses the weight of raw materials to be processed as a drive force, as well as reduces the number of necessary external equipment involved in processing. The energy generated by the proposed apparatus can be accumulated for further implementation of technical support at other stages of collection, transportation, storage, utilization or recovery of waste. The work provides for operating practices and variants of the unit design to carry out the cleaning processes for its working surfaces and to normalize operation during emergencies. In order to improve the energy saving level of processes for crushing equipment transportation, a self-propelled modification of the proposed apparatus has been developed that uses generated electric energy to supply with electricity the electric motors of single or combined mobile platforms while delivering the equipment to the place of operation. Conclusions. The presented materials can be effectively used to improve the ecological-economic efficiency of exploiting the material-technical base of systems for sanitary cleaning of settlements, to reduce the specific consumption of electric energy required when processing solid waste and can be used for modernization and functioning of a network of mobile crushing equipment.
