Abstract
The invention discloses an equipment for preparing medical natrium bicarbonicum, which comprises a carbonizer, a natron dissolving tank communicated with the carbonizer body, a carbon dioxide storage tank communicated with the top of the carbonizer and a plurality of cooling channels communicated with the carbonizer. The cooling channels are communicated with a cyclone separator which is communicated with a wash channel. The wash channel is communicated with another cyclone separator which is communicated with a drier. A natran solution inlet and a product outlet are respectively arranged at the top and the bottom of the carbonizer body. A carbon dioxide inlet and a carbon dioxide reclaiming interface are respectively arranged on the carbonizer cover. A gas-liquid separating plate is arranged between the carbonizer body and the carbonizer cover. The lower part of the lower gas-liquid separating plate is provided with a carbon dioxide distributor. The equipment receives the carbon dioxide from the top of the carbonizer and evenly distributes the carbon dioxide in the natron solution to prepare medical natrium bicarbonicum by carburizing reaction. The equipment has the advantages of high carbonization efficiency and the particles produced are even and fine and are easily dissolved and used.
Description
technical field [0001] The invention belongs to a device for producing sodium bicarbonate, in particular to a device for preparing medicinal sodium bicarbonate by using carbon dioxide gas and sodium carbonate solution to carry out carbonization reaction through a carbon dioxide gas distributor in a carbonization tower. Background technique [0002] At present, the general preparation of medicinal sodium bicarbonate is to utilize carbon dioxide gas and sodium carbonate to carry out carbonization reaction in the carbonization tower, and the carbonization reaction takes place on the mushroom caps on the walls around the carbonization tower. The sodium carbonate solution enters from the top of the carbonization tower, and the carbon dioxide gas enters the tower body from the bottom of the carbonization tower, and the carbonization reaction takes place on the mushroom cap. The above-mentioned existing process equipment for preparing sodium bicarbonate has low carbonization effici...
