Description

Technical Field

[0001] This utility model belongs to the field of distillation column technology, specifically relating to a high-efficiency heat transfer distillation column tray assembly. Background Technology

[0002] Distillation columns are core equipment in the chemical industry used to separate liquid mixtures. They extract high-purity components by utilizing the differences in boiling points among the components in the mixture. Existing tray assemblies generally suffer from limited gas-liquid contact area. For example, in conventional sieve tray columns, the gas phase rises only through fixed apertures, while the liquid phase flows unidirectionally on the tray surface, resulting in a short mass transfer path, insufficient turbulence effect, and low heat transfer efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-efficiency heat transfer distillation column tray assembly, which solves the problems mentioned in the background art.

[0004] The purpose of this invention is achieved as follows: A high-efficiency heat transfer distillation column tray assembly includes a column body. At least two sets of tray bodies are staggered on the inner wall of the column body. Each set of tray bodies has equidistantly distributed vapor holes at its top, and a filter screen is installed inside each vapor hole. A connecting pipe communicating with the vapor holes is fixedly connected to the top of each tray body. A liftable cover plate is provided above the connecting pipe, and the bottom of the cover plate is connected to the connecting pipe via a first elastic element. A dynamic adjustment assembly is provided between adjacent sets of tray bodies. The dynamic adjustment assembly includes a guide plate, and the guide plate is connected to a servo motor. In use, the distribution of vapor holes extends the gas-liquid flow path, and the filter screen reduces droplet entrainment, ensuring uniform gas phase distribution. The servo motor drives the guide plate to change its angle, and combined with sensor feedback, adaptive optimization of the gas-liquid contact area is achieved, improving heat transfer efficiency. Compared with the fixed outlet pipe structure of the prior art, the heat transfer efficiency can be improved by 15-20%, achieving high-efficiency heat transfer.

[0005] Furthermore, the dynamic adjustment component also includes: corrugated guide grooves on the surface of the guide plate, the depth of which decreases from the center to both sides; a temperature sensor and a pressure sensor are embedded in the bottom of the guide plate, and the sensor signals are connected to the control system to adjust the speed of the servo motor. The corrugated guide grooves increase the turbulence effect and promote interphase heat transfer.

[0006] Furthermore, an elastic sealing ring is provided between the cover plate and the connecting pipe. The elastic sealing ring is made of fluororubber and has a V-shaped cross-section to enhance airtightness.

[0007] Furthermore, the edge of the tower plate body is provided with a retractable extension, which is connected to the inner wall of the tower body by a return spring, and the surface of the extension is provided with auxiliary flow guide holes.

[0008] Furthermore, the corrugated guide groove is embedded with a graphene coating, the thickness of which is 50-100 μm and the thermal conductivity is ≥1500 W / (m·K).

[0009] Furthermore, the steam holes of two adjacent sets of the tower plate bodies are staggered, with a stagger distance of 1.2-1.5 times the diameter of the steam hole.

[0010] Furthermore, the bottom of the tower body is provided with support legs, and the support legs integrate shock absorbers. The damping coefficient of the shock absorbers is adjustable in the range of 0.5-2.0 N·s / mm.

[0011] The beneficial effects of this invention are as follows: The distribution of steam holes extends the gas-liquid flow path, and the filter screen reduces droplet entrainment, ensuring uniform gas phase distribution. A servo motor drives the guide plate angle change, combined with sensor feedback, to achieve adaptive optimization of the gas-liquid contact area, improving heat transfer efficiency. The corrugated guide grooves increase turbulence, promoting interphase heat transfer. Compared to the fixed exhaust pipe structure of existing technologies, heat transfer efficiency can be improved by 15-20%, achieving highly efficient heat transfer. Attached Figure Description
