Abstract

The invention belongs to the technical field of chemical production recovery, and particularly relates to a cooling flame-retardant recovery system for combustible solid waste particles. The system comprises a cooling conveying pipeline, the inlet end of a cooling conveying bin pump is connected with a calcium carbide furnace purification device and a high-pressure nitrogen main pipeline, the outlet end of the cooling conveying bin pump pipeline is connected with the top of a low-temperature material bin, the solid waste is conveyed to the top of the low-temperature material bin through low-temperature nitrogen, a nitrogen recovery dust collector is further arranged at the top of the low-temperature material bin, recovered nitrogen is filtered through a precision filter and then pressurized through a nitrogen compressor, the pressurized nitrogen is introduced into a nitrogen recovery main pipeline again to be recycled, and the bottom of the low-temperature material bin is connected with a combustible solid waste boiler through an air conveying bin pump conveying pipeline. According to the system, the labor intensity of field workers is reduced, the production cost is reduced, and the field environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of chemical production and recycling, and in particular relates to a cooling and flame-retardant recycling system for combustible solid waste particles. Background technique [0002] The calcium carbide furnace purification device in the calcium carbide plant will produce combustible solid waste with certain combustibility. If it is recycled at the original site, it can reduce the company's production cost, improve equipment utilization, reduce labor intensity, and reduce the waste caused by solid waste. Environmental pollution caused by transportation. However, when such high-temperature combustible materials are recycled, deflagration and explosion accidents are prone to occur during pipeline transportation, which is an urgent problem to be solved in recycling work. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a cooling and f...
