DETAILED DESCRIPTION

[0027] Please refer to Figures 1-5 Among them, Figure 1 The overall structure schematic view of the glass lining rectifying column kettle provided by the utility model; Figure 2 The sectional structure schematic view of the glass lining rectifying column kettle provided by the utility model; Figure 3 The partition plate structure schematic view of the glass lining rectifying column kettle provided by the utility model; Figure 4 The partition plate cap body structure explosion view of the glass lining rectifying column kettle provided by the utility model; Figure 5 The partition plate sectional structure schematic view of the glass lining rectifying column kettle provided by the utility model. The glass lining rectifying column kettle comprises a rectifying column kettle body 1, a feed pipe 2 is fixedly installed on one side of the top of the rectifying column kettle body 1, a high-boiling material discharge pipe 3 is fixedly installed at the bottom of the rectifying column kettle body 1, a plurality of partition plates 4 are fixedly installed in the rectifying column kettle body 1, a vertical plate 5 is fixedly installed on one side of the plurality of partition plates 4, a plurality of through holes 6 are formed in the partition plates 4, a round pipe 7 is connected to the top of the through holes 6, a cap body 8 is sleeved on the round pipe 7, and the bottom of the cap body 8 is fixedly connected with the partition plates 4.

[0028] As Figure 1 Indicated, one side of the rectifying column kettle body 1 is provided with a condensing tower 9, a conveying pipe 10 is fixedly installed at the top of the rectifying column kettle body 1, one end of the conveying pipe 10 is communicated with one side of the condensing tower 9, a low-boiling material discharge pipe 11 is fixedly installed at the bottom of the condensing tower 9, and an exhaust pipe 18 is fixedly installed at the top of the condensing tower 9;

[0029] The steam rising in the rectifying tower kettle body 1 is transported to the condensing tower 9 through the conveying pipe 10, and the steam is condensed into liquid in the condensing tower 9, discharged through the low-boiling-point material discharge pipe 11, and the non-condensable gas is discharged from the exhaust pipe 18, so as to ensure the smooth progress of the condensation process.

[0030] As shown in Figure 2 , the rectifying tower kettle body 1 is provided with a reboiler 12 on one side, and the bottom of the reboiler 12 is fixedly installed with a material extraction pipe 13, one end of the material extraction pipe 13 is fixedly connected with the high-boiling-point material discharge pipe 3;

[0031] As shown in Figure 2 , the top of the reboiler 12 is fixedly installed with a gas phase pipe 14, and the side of the reboiler 12 is fixedly installed with a liquid phase pipe 15, one end of the gas phase pipe 14 and the liquid phase pipe 15 is fixedly connected with the rectifying tower kettle body 1;

[0032] Part of the material at the high-boiling-point material discharge pipe 3 is extracted to the reboiler 12 through the material extraction pipe 13 by the liquid extraction pump 17, so that part of the material is heated and vaporized, and the vaporized material returns to the rectifying tower kettle body 1 through the gas phase pipe 14 to provide a heat source for rectification;

[0033] The liquid phase pipe 15 introduces the excess high-boiling-point material in the reboiler 12 into the rectifying tower kettle body 1 again, so as to avoid too much high-boiling-point material in the reboiler 12 affecting the introduction of the gas phase pipe 14.

[0034] As shown in Figures 3-5 , a plurality of gas outlet holes 16 are formed in the cap body 8, and the plurality of gas outlet holes 16 are arranged in an annular array;

[0035] The rising steam can be discharged from the cap body 8 through the gas outlet hole 16, and contacted with the liquid above the partition plate 4, so as to promote heat exchange between gas and liquid and evaporate the low-boiling-point material.

[0036] As shown in Figure 2 , the material extraction pipe 13 is fixedly installed with a liquid extraction pump 17;

[0037] The liquid extraction pump 17 provides power to ensure that the material at the bottom of the tower kettle can be smoothly extracted to the reboiler 12, and the continuous progress of the reboiling process is ensured.

[0038] As shown in Figure 2 , a plurality of the partition plates 4 are stacked and staggered in the rectifying tower kettle body 1 from top to bottom, and the top of the plurality of the circular pipes 7 is slightly higher than the top of the vertical plate 5;

[0039] The through holes 6 on the plurality of the partition plates 4 are distributed on the inner sides of the adjacent two vertical plates 5.

[0040] The material is heated sufficiently by the staggered distribution of the baffles 4, the extension of the material flow path in the tower and the increase of the residence time; the top of the circular tube 7 is higher than the vertical plate 5, so that the material can overflow when the material on the baffle 4 accumulates to the height of the vertical plate 5, and the steam is discharged from the gas outlet 16 of the cap 8 to fully contact with the material, thereby improving the heat exchange efficiency; the through hole 6, the circular tube 7 and the cap 8 are arranged in the vertical plate 5, and the heat is concentrated on the material accumulation position of the plurality of baffles 4, thereby improving the heat exchange efficiency of the liquid and the gas.

[0041] The working principle of the glass lining rectifying tower kettle is as follows:

[0042] The first step is that the preheated material enters the rectifying tower kettle body 1 through the feeding pipe 2, and the material flows on the plurality of staggered baffles 4; since the baffles 4 are staggered, the material flow path is extended, the residence time is increased, the material is uniformly heated in the flow process, and the low-boiling-point material is gradually evaporated;

[0043] The second step is that the liquid pump 17 is started to pump part of the material at the high-boiling-point material discharge pipe 3 to the reboiler 12, so that part of the high-boiling-point material is heated and evaporated to form steam, which is introduced into the rectifying tower kettle body 1 through the gas phase pipe 14;

[0044] The third step is that the steam enters the circular tube 7 through the through hole 6, and is discharged from the gas outlet 16 of the cap 8 to contact with the material above the baffle 4, so as to exchange heat, evaporate the low-boiling-point material, reduce the temperature of the high-boiling-point material steam, and gradually liquefy the high-boiling-point material, which is combined with the flowing material; finally, the high-boiling-point material is concentrated at the bottom of the rectifying tower kettle body 1 and is discharged from the high-boiling-point material discharge pipe 3, and the low-boiling-point material steam is transported to the condensing tower 9 through the conveying pipe 10, so as to condense and liquefy the low-boiling-point material, which is finally discharged through the low-boiling-point material discharge pipe 11.
