Carbon dioxide high-purity processing preparation system device based on calcium carbonate crushing and decomposing
The invention discloses a carbon dioxide high-purity processing preparation system device based on calcium carbonate crushing decomposition, and relates to the technical field of carbon dioxide preparation. According to the invention, a calcium carbonate supply device is connected with a vacuum pumping device, an output port of the calcium carbonate supply device is connected with a feeding pipe, the feeding pipe is sequentially provided with a crushing device, a centrifugal pump, a dust concentration flowmeter and a dust flow meter, and the downstream end of the feeding pipe is connected with a carbon dioxide generating device. A circuitous heating pipeline is arranged in the carbon dioxide generating device, a long heating device is arranged on the straight pipeline, an air pressure sensing device is arranged on the heating-free turning pipe, the heating-free turning pipe is connected with a pressure reduction return pipe located on the downstream portion of the air pressure sensing device, and the downstream end of the pressure reduction return pipe is communicated with a main breather pipe. The carbon dioxide generating device comprises a calcium oxide concentration cavity. The calcium oxide separation and collection in the calcium carbonate decomposition process are realized, the preparation purity of the carbon dioxide gas is improved, and the heating energy consumption is also reduced to a certain extent.
