Stage-style variable frequency carbon dioxide enrichment method

Abstract

The invention relates to the technical field of gas enrichment devices and provides stage-style variable frequency carbon dioxide enrichment equipment. The stage-style variable frequency carbon dioxide enrichment equipment comprises a spraying chamber which is connected with a flue of a reacting furnace through a pipeline; a plurality of spraying devices are arranged at the top of the spraying chamber and each spraying device comprises a carbon dioxide detector and a plurality of spraying nozzles, the spraying nozzles are connected with a total water path through branch water paths, and a variable frequency water pump is arranged on each branch water path; the carbon dioxide detector and the variable frequency water pumps are in signal connection with the controller; the carbon dioxide detector is used for transmitting detected carbon dioxide concentration signals to the controller; the controller is used for generating control signals according to the carbon dioxide concentration signals and transmitting the control signals to the variable frequency water pumps; the variable frequency water pumps are used for regulating the outlet water quantity of the spraying nozzles according to the control signals. According to the stage-style variable frequency carbon dioxide enrichment equipment, the carbon dioxide absorption efficiency can be improved, and the cost can be saved.

Description

technical field [0001] The invention relates to the technical field of gas enrichment devices, in particular to a staged frequency conversion carbon dioxide enrichment device. Background technique [0002] The existing magnesite smelting process will produce a large amount of carbon dioxide gas, and the generation of carbon dioxide gas may have the characteristics of intermittent surges. The existing way of absorbing carbon dioxide is generally ammonia water spraying, and a constant amount of ammonia water spraying is adopted. However, since the concentration of carbon dioxide may rise intermittently during smelting of magnesite, it will not be able to completely absorb carbon dioxide, and more ammonia water will be wasted, which will increase the cost of absorbing carbon dioxide and cause waste of resources. Contents of the invention [0003] The object of the present invention is to propose a staged frequency conversion carbon dioxide enrichment device to achieve the pu...
