Safety and environmental protection treatment system and treatment process of calcium carbide slag in cement production and storage

Abstract

The invention discloses a safe and environmentally friendly treatment system and process for carbide slag in cement production and storage, which solves the problem of accumulation of acetylene gas in the storage silo of carbide slag by using a replacement method, and utilizes high-temperature kiln tail gas produced by cement to heat The gas containing carbide slag dust is exchanged from the carbide slag storage silo, so that the dry high-temperature carbide slag dust gas is filtered through the bag filter, and the carbide slag is returned to the system for reuse, and the gas that meets environmental protection standards is directly discharged, which effectively solves the problem The calcium carbide slag storage silo is prone to explosion due to the accumulation of acetylene gas, and it also solves the problem of blockage of pipes, valves, and internal components of the dust collector in the dust removal system. The invention has the advantages of less land occupation, less investment, high efficiency, safety, energy saving, environmental protection, 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...
