Carbonization device for recycled concrete aggregate from solid waste for concrete

Abstract

The invention belongs to the technical field of carbon dioxide sequestration and solidification, in particular to a carbonization device for regenerated concrete aggregates from solid waste for concrete, aiming at direct discharge of CO2 gas in the carbonization bin when feeding materials, and even carbon dioxide poisoning in severe cases. For the technical problem of low safety, the following proposals are proposed, including a carbonization box with a waste discharge port at the upper end, a sealing assembly at the waste discharge port, the sealing assembly includes a first seal and a second seal, and the second The first seal and the second seal are respectively located on the upper and lower sides of the waste input port and are fixedly connected with the carbonization box. In the present invention, the first sealing member and the second sealing member are respectively arranged on the upper and lower sides of the waste input port, and the first sealing member and the second sealing member are respectively used to realize the sequential discharging of the first step of discharging and the second step of discharging. , which can effectively avoid the overflow of carbon dioxide gas inside the box during the feeding process and improve the safety in the working process.

Description

technical field [0001] The invention relates to the technical field of carbon dioxide sequestration and solidification, in particular to a carbonization device for regenerating concrete aggregates from solid waste for concrete. Background technique [0002] The industrial waste generated in the process of industrial production increases rapidly with the rapid development of the industry. The waste generated by domestic enterprises cannot be disposed of in time, resulting in a large amount of waste residue occupying land and polluting the environment. The application of industrial waste residues as building materials has become the main way of its resource application. At present, in the field of civil engineering materials, wastes such as steel slag and waste concrete can be directly crushed and used as concrete aggregates, which has a good economic effect. These solid waste residues are generally highly alkaline and have strong CO2 absorption capacity. Current research s...

Problems solved by technology

[0004] Most of the existing experimental devices are open, and the experimental process requires manual opening of the carbonization chamber door to complete the feeding, resulting in the direct emission of CO2 gas in the carbonization chamber, and even carbon dioxide poisoning in severe cases, which is less safe. Technical problem, the present invention proposes a carbonization device for recycled concrete aggregate from solid waste for concrete
