Safe and environment-friendly treatment system for carbide slag in cement production and storage and treatment process of safe and environment-friendly treatment system

Abstract

The invention discloses a safe and environment-friendly treatment system for carbide slag in cement production and storage and a treatment process of the safe and environment-friendly treatment system. The problem of accumulation of acetylene gas in a carbide slag storage bin is solved through a replacement method; carbide slag dust-containing gas replaced from the carbide slag storage bin is heated by using high-temperature kiln exhaust gas produced by cement, so that after the dry carbide slag dust-containing gas is filtered through a bag dust remover, the carbide slag returns to the systemfor recycling; environmentally-friendly and standard-meeting gas is directly discharged; the problem that the carbide slag storage bin is extremely easy to explode due to the accumulation of the acetylene gas is effectively solved, and the problem of blockage of internal components of a pipeline, a valve and a dust remover in a dust removal system is also solved. The safe and environment-friendlytreatment system has the advantages of a small occupied space, small investment, high efficiency, safety, environmental friendliness, economical operation and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a safe and environment-friendly treatment system and a treatment process suitable for the by-product calcium carbide slag produced in the process of calcium carbide dry acetylene production in cement production and storage. Background technique [0002] Regarding the reuse of calcium carbide slag produced in the dry acetylene production plant, "new construction, reconstruction and expansion of calcium carbide process polyvinyl chloride projects must be accompanied by the construction of carbide slag comprehensive utilization devices such as carbide slag cement production" is the current national industrial development policy orientation. Under the guidance of national policies, the supporting construction of calcium carbide slag cement plant has been successively built and put into operation. In the process of using calcium carbide slag to make cement, becau...
