Carbonizing device for solid waste recycled aggregates for concrete

Abstract

The invention discloses a carbonizing device for solid waste recycled aggregates for concrete. The device comprises a loading bin, a drum type carbonizing bin and a storage bin, wherein the loading bin and the storage bin are arranged on two ends of the drum type carbonizing bin in a sealing way; a circumferential rack is arranged on an outer surface of the drum type carbonizing bin, and is meshedwith a fixed motor transmission gear. A double-spiral turnover plate is arranged on an inner cylinder wall of the drum type carbonizing bin. The loading bin is provided with a carbon dioxide air inlet, and a feed hopper is arranged on the end part; a discharging leakage pipe is arranged on the bottom part of the storage bin. The feed hopper is sealed by a valve closed by automatic rebound, and adischarge hole is sealed by a water tank. The carbonizing device not only realizes continuous production of recycled aggregates carbonizing, but also realizes full seal of a carbonizing space, guarantees that no CO2 gas is lost during a carbonizing process, and provides a way for industrial production of solid waste recycled aggregates carbonizing. Meanwhile, according to the carbonizing device, the recycled aggregates can fully absorb the CO2 gas, and the mechanical strength of the recycled aggregates is greatly improved.

Description

technical field [0001] The invention relates to a device for solidifying and absorbing carbon dioxide by solid waste residue, in particular to a carbonization device for solid waste recycled concrete aggregate, which belongs to the field of carbon dioxide sequestration and solidification. Background technique [0002] CO 2 Global warming caused by excessive emissions has been highly valued by countries all over the world. Problems such as the melting of polar glaciers, rising sea levels, submerged islands, extinction of animals and plants, frequent meteorological disasters, and the spread of infectious diseases are increasingly endangering human beings. living space. Therefore, various international agencies, climate organizations and governments are looking for ways to reduce CO2 emissions. 2 the fastest and most efficient way. Reduce the use of fossil fuels such as coal, oil, and natural gas; make more use of new energy sources such as nuclear energy, solar energy, wind...
