Description
Technical Field
The utility model relates to the technical field of chemical equipment, in particular to a novel packing multitube tower.
Background
Rectification is a separation process for separating components by utilizing different volatilities of the components in a mixture, and is usually carried out in a rectifying tower, and gas-liquid two phases are in countercurrent contact to carry out phase-to-phase heat and mass transfer. The volatile components in the liquid phase enter the gas phase, and the less volatile components in the gas phase are transferred to the liquid phase, so that almost pure volatile components can be obtained at the top of the tower and almost pure less volatile components can be obtained at the bottom of the tower.
The feed liquid is added from the middle part of the tower, and the tower section above the feed inlet is used for further thickening volatile components in rising steam, which is called a rectifying section; and a tower section below the feed inlet is used for extracting volatile components from the descending liquid and is called stripping section. And condensing vapor led out from the top of the tower, wherein a part of condensate is used as reflux liquid and returns to the rectifying tower from the top of the tower, and the rest distillate is the top product. The liquid extracted from the bottom of the tower is gasified by the reboiler, the vapor rises along the tower, and the rest liquid is used as the bottom product. The ratio of the amount of liquid flowing back into the column at the top of the column to the amount of product at the top of the column is called reflux ratio, and its size affects the separation effect and energy consumption of the rectification operation.
Common equipment is a plate rectifying tower and a packed rectifying tower.
The plate tower is a gas-liquid mass transfer equipment with very wide application, and is composed of a shell body with a general cylindrical shape and several plates horizontally arranged at a certain interval. When the plate tower works normally, liquid passes through each layer of tower plate from top to bottom under the action of gravity and is discharged from the bottom of the tower; the gas is pushed by pressure difference, passes through all layers of tower plates from bottom to top through holes uniformly distributed on the tower plates, is discharged from the tower top, and is stored with certain liquid on each tower plate, and when the gas passes through the liquid layer on the plate, the two phases are contacted for mass transfer.
The packed tower is a gas-liquid mass transfer device with a large amount of packing in the tower as an inter-phase contact member. The packing is a core component of the packing tower, and provides a phase interface for gas-liquid two-phase contact mass transfer, which is a main factor determining the performance of the packing tower. The types of fillers are various, and can be divided into two main types of bulk fillers and structured fillers according to different filling modes.
The bulk packing is a particle body with a certain geometrical shape and size, is generally piled up in a tower in a bulk mode, is also called random packing or particle packing, and can be divided into annular packing, saddle packing, spherical packing and the like according to different structural characteristics, and the typical bulk packing mainly comprises: raschig ring packing, pall ring packing, stepped ring packing, arc saddle packing, metal ring saddle packing and spherical packing; the structured packing is arranged in a tower according to uniform geometric figure, and is characterized by defining a gas-liquid flow path, improving the gas-liquid distribution condition in the packing layer, and providing more specific surface area under very low pressure drop, so that the processing capacity and mass transfer performance are improved to a great extent.
The large-scale packed tower adopted in chemical plants generally has the advantages that the tower diameter and the size of the packing are large, the specific contact area of the gas phase and the liquid phase is small, and the serious wall flow phenomenon and channeling phenomenon exist, so that the mutual contact of the gas phase and the liquid phase is uneven on different sections or different radiuses, the performance of the tower is quite large, and the separation efficiency is rapidly reduced along with the increase of the tower diameter.
Therefore, the general industrial packing tower is characterized in that the capacity of treating materials increases with the increase of the tower diameter, and the separation efficiency is reduced, but on the contrary, the separation efficiency of small-particle packing and small-diameter tower is found to be abnormally high, and the material treatment capacity is very small. The multi-pipe type high-efficiency packed tower is characterized in that a plurality of high-efficiency small-diameter towers are arranged in parallel to form a tower with a large diameter, so that the contradiction is solved, and the high-efficiency packed tower can meet the requirement of high separation efficiency and can improve the production capacity.
The present inventors found that there are at least the following technical problems in the prior art:
the existing two main structures of the multi-tube tower are an independent kettle type multi-tube tower and a common kettle type multi-tube tower. The tower bottoms of the independent kettle type multi-pipe tower are independent, and the tower top steam is communicated and used for extracting heavy components. The bottoms of the common kettle type multi-pipe tower are communicated, and the tops of the towers are respectively condensed and extracted, and are generally used for extracting light components. However, the number of unit equipment of the two multi-pipe towers is large, so that the equipment manufacturing, maintenance and control are complex, and the uniformity is poor.
