Description

Technical Field

[0001] The utility model belongs to the technical field of distillation towers in fine chemical industry, in particular to a filling device for a distillation tower. Background Art

[0002] The distillation tower is a mass and heat transfer device that is widely used in fine chemical production. It is also a tower-type vapor-liquid contact device for distillation. It utilizes the different volatility between the components of the liquid mixture to complete the separation and purification of the mixture through the step-by-step flow and contact of the gas-liquid two phases to transfer mass and heat across the interface.

[0003] The packing in the packed distillation tower is generally in the form of metal mesh or ceramics. Metal mesh packing is widely used due to its high strength. Metal mesh packing is made of wire mesh cut into a certain shape and then bound. Therefore, during use, burrs left during cutting or rust and other debris falling off the wire are easy to fall onto the distributor provided in the distillation tower along with part of the liquid output from the condenser. Over a long period of time, the holes on the distributor will be blocked, which will further affect the contact between the gas and liquid phases, thereby affecting the distillation efficiency.

[0006] In order to limit the liquid phase and gas phase in the packed tower cylinder, preferably, the connection point between the heat medium outlet and the packed tower cylinder is higher than the connection point between the steam inlet and the material inlet and the packed tower cylinder, the connection point between the heat medium inlet and the packed tower cylinder is higher than the connection point between the heat medium outlet and the packed tower cylinder, the connection point between the reflux port and the packed tower cylinder is higher than the connection point between the heat medium inlet and the packed tower cylinder, and the connection point between the gas phase outlet and the packed tower cylinder is located at the topmost end of the packed tower cylinder.

[0007] In order to observe the reaction, further, there are multiple viewing windows, and the positions of the connecting points between the viewing windows and the packing tower cylinder match the distillation packing.

[0008] In order to push the impurities into the filter ring, preferably, the top surface of the filter plate is an arc-shaped surface, and the scraper block is an arc-shaped block matching the top surface of the filter plate.

[0009] In order to clean the impurities on the filter ring, preferably, a rotating door panel matching the filter ring is rotatably mounted on the side end of the packing tower cylinder.

[0021] The connection point between the heat medium outlet 6 and the packed tower cylinder 1 is higher than the connection point between the steam inlet 4 and the material inlet 5 and the packed tower cylinder 1, the connection point between the heat medium inlet 7 and the packed tower cylinder 1 is higher than the connection point between the heat medium outlet 6 and the packed tower cylinder 1, the connection point between the reflux port 8 and the packed tower cylinder 1 is higher than the connection point between the heat medium inlet 7 and the packed tower cylinder 1, the connection point between the gas phase outlet 9 and the packed tower cylinder 1 is located at the top of the packed tower cylinder 1, there are multiple windows 10, and the positions of the connection points between the windows 10 and the packed tower cylinder 1 match the distillation packing 11, which restricts the connection points between the steam inlet 4, material inlet 5, heat medium outlet 6, heat medium inlet 7, window 10, reflux port 8 and gas phase outlet 9 and the packed tower cylinder 1, thereby achieving control of liquid and gas phase input and output.

[0022] The top surface of the filter plate 14 is an arc-shaped surface, and the scraper block 16 is an arc-shaped block that matches the top surface of the filter plate 14. The arc-shaped surface can facilitate the flow of impurities from high to low to the filter ring 15.

The rotating motor 3 is started, and the rotating shaft 13 drives the scraper 16 to rotate on the filter plate 14. The impurities on the filter plate 14 are pushed into the filter ring 15 by the scraper 16, and the filter plate 14 that is not blocked by impurities continues to filter.
