SU1242468A1 - Chlorinator for producing anhydrous melt of carballite - Google Patents

Description

2, the Chlorinator according to claim 1, and tl and h aa-ui and so that the coaxially arranged cylinders of the hydrogen chloride generator are made with a ratio of diameters of 0.5-0.7, -.

one

The invention relates to the metallurgy of light metallob, in particular to the electrolytic production of magnesium and chlorine.

The purpose of the invention is to reduce the loss of magnesium chloride, to increase the specific productivity and service life of the chlorinator.

The drawing shows a chlorinator, a general view. in a cut.

The chlorinator consists of a communicator between the melter 1 and the Hoi o raw material 5 of the chlorinating chamber 2 and the accumulator 3 for accumulation and melt-free melt. The melt 1 is connected to the chlorinating chamber 2 by the overflow channel 4, the horizontal perforated edge 5 is placed in the melter 1, lance b with 1; a hydrogen chloride generator, made of two coaxially mounted cylinders 7 and 8.

The chlorinator works as follows.

Partially dehydrated carnallite with a water content of 3 May,% and oxide of 2 wt.%, Continuously enters the melter, in which it is heated, melted and dehydrated. Simultaneously with the supply of dehydrated carnallite, the melter 1 under the horizontal perforated partition 5 from lance 6 enters the gas mixture 5 state and 1; a (60–80%) from hydrogen hydrogen compounds and containing solid carbon in the form of soot, obtained by burning a mixture of anodic and natural gas in a ton of hydrogen chloride. The gas flow is evenly distributed by means of a horizontal perforated partition 5 over the entire cross section of the smelter 1.

:. An atorator according to claim 1, wherein the perforated partition is installed relative to the tuyere opening of the tuyere at a height of 0.3-0.4 from the height of the melter to the overflow channel.

Thus, the melting and dehydration of carnallite takes place in a flow of chlorine stock of hydrogen, ch1-o suppresses the hydrolysis of magnesium chloride. As a result of this, the loss of raw materials decreases and the specific productivity of the chlorinator increases. The melt stream containing the carbonaceous reducing agent flows from the melter through the overflow channel 4 to the chlorinating chamber 2, the hernia is chlorinated the hydrolysis residual products with chlorine and then sent to the digger 3. Finally, the melt is anhydrous, I o carnalpit is clarified electrolysis to obtain maxi and chlorine,

The table shows the performance of chlorine gases obtained as a result of testing known pro- vtbiraneHHOi o and the proposed chlorinators, as well as the results of tests of the proposed chlorinator if the optimal values do not comply with the ratios of the diameters of coaxial cylinders (3, / с1, and the ratio of the height of the placement of the septum to the height of the hopper hi / b "

The results show a significant increase in the duration of the chlorinator to 18 months versus 2 months. In a known chlorinator, an increase in productivity from 450 to 495-500 K1 / MH and a decrease in magnesium chloride losses by 2-3%,

The advantage of the proposed chlorinator is that the carbonaceous reducing agent, necessary for the chlorination of hydrolysis products in the chlorination chamber, is obtained in a hydrogen chloride generator, thus a complex transport system 1 is not required for the delivery of the carbonaceous reducing agent to the chlorinator,
