Research of Technical Solutions to Environmental and Energy Problems During Pyrolysis Processing of Large-Tonnage Solid Organic Waste

. Large-tonnage solid organic waste [LSOW], such as beet pulp, beer pellets, spent activated sludge [SAS], and ion exchange resins [IER], are formed in large quantities at food and chemical enterprises in Russia. Currently, a large number of methods of processing and disposal are known for these LSOW (use as raw feed or for obtaining feed additives for animals, canning in silage or pulp pits, use as raw materials for biogas production, drying, use as raw materials for obtaining useful components). However, these methods allow only a small amount of LSOW to be processed or disposed of. The main part of LSOW is stored in landfills or silt maps. It is necessary to develop a technical solution to environmental and energy problems in the pyrolysis processing of LSOW. For it, the authors carried out the experimental studies of the pyrolysis processing of LSOW on a laboratory installation. It will include a horizontal pyrolysis reactor, loading and unloading devices, two condensers. As a result, the dependences of the yields of secondary products on the temperature of the pyrolysis process are obtained. The authors established that secondary products are formed in the process of thermal processing of LSOW: liquid fraction; solid residue; pyrolysis gas. The obtained secondary products have a different yield by weight depending on the pyrolysis temperature, but the graphical dependencies are similar for all the studied LSOW. The authors developed a block diagram of a universal pyrolysis plant for processing waste from various industries. It includes three sections:pyrolysis disposal section; solid residue gasification section; liquid fraction separation section.
