Description

Technical Field

[0001] This utility model relates to the field of distillation column technology, specifically a distillation column with a coil condenser. Background Technology

[0002] A distillation column is a tower-type vapor-liquid contact device used for distillation. It utilizes the different volatility of the components in a mixture—that is, the different vapor pressures of the components at the same temperature—to transfer lighter components (low-boiling substances) from the liquid phase to the vapor phase, while heavier components (high-boiling substances) from the vapor phase transfer to the liquid phase, thus achieving separation. Distillation columns are also a widely used mass and heat transfer device in petrochemical production.

[0003] Application number CN202020788179.2 discloses a novel wall-mounted distillation column, including a base, a wall-mounted distillation column body, a preheating box, and an air-cooled box. This invention, through a series of structural features, enables the device to effectively utilize energy and cool hot gas. While this application can utilize waste heat to preheat raw materials, the preheating is incomplete and the preheating effect is poor. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A distillation column with a coil condenser includes a feeding mechanism and a preheating mechanism. The feeding mechanism includes a column body, an outer shell disposed on one side of the column body, a material flow channel connecting the column body and the outer shell, and a preheating box that is attached to the inner side walls of the outer shell. The preheating box communicates with the interior of the column body through the material flow channel. The preheating mechanism includes a hydraulic cylinder connected between the outer shell and the preheating box, a metal plate suspended at the bottom of the inner cavity of the preheating box, a plurality of connecting rods connecting the top of the inner cavity of the outer shell and the top of the metal plate, and a hot gas pipe connecting the column body and the outer shell.

[0007] By adopting the above technical solution, the high-temperature gas generated during the operation of the tower is injected into the preheating box through the hot gas pipe to create a preheating environment for the raw materials. Then, because the metal plate is located directly below the hot gas pipe, the metal plate will be heated quickly. When the raw materials are put into the preheating box, the raw materials roll along the bottom of the preheating box cavity towards the material conveying channel. At the same time, the moving end of the hydraulic cylinder reciprocates to stretch the preheating box. Then, the metal plate and the preheating box work together to continuously rub and heat the surface of the raw materials, thereby improving the preheating effect of the raw materials.

[0008] In a preferred embodiment, the present invention can be further configured such that the preheating box is inclined, and the bottom of the inner cavity of the preheating box and the bottom of the inner cavity of the material conveying channel are located on the same horizontal plane.

[0009] In a preferred embodiment, the present invention can be further configured such that: the metal plate is set in the shape of "﹂", the metal plate is parallel to the bottom of the preheating box cavity, and the length and width of the metal plate are the same as the length and width of the preheating box.

[0010] In a preferred embodiment, the present invention can be further configured such that: multiple connecting rods at equal intervals on the top of the metal plate are arranged in a row, and both the metal plate and the connecting rods are made of metal material.

[0011] In a preferred embodiment, the present invention can be further configured such that: a cooling mechanism is provided on the front side of the outer shell, the cooling mechanism includes an exhaust pipe connected and communicating with the outer shell, and a condenser provided on the front side of the exhaust pipe, the exhaust pipe being located at the bottom of the preheating box.

[0012] In a preferred embodiment, the present invention can be further configured such that: a feed pipe is connected and communicated at the top of the outer shell, and the hot gas pipe is located between the tower body and the feed pipe.

[0013] In a preferred embodiment, the present invention can be further configured such that: an outer frame is fitted around the outside of the tower body, the bottom of the outer shell and the condenser are both connected to the top of the outer frame, and a guardrail is installed on the top of the outer frame.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, the high-temperature gas generated during the operation of the tower body is injected into the preheating box through the hot gas pipe to create a preheating environment for the raw materials. Then, because the metal plate is located directly below the hot gas pipe, the metal plate will be heated quickly. When the raw materials are put into the preheating box, the raw materials roll along the bottom of the preheating box cavity towards the material conveying channel. At the same time, the moving end of the hydraulic cylinder reciprocates to stretch the preheating box. Then, the metal plate and the preheating box work together to continuously rub and heat the surface of the raw materials, thereby improving the preheating effect of the raw materials.

[0016] 2. In this utility model, when the high-temperature hot gas inside the outer shell is discharged, it will be cooled by the condenser. The condenser improves the environment around the tower and enhances the comfort of operation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a distillation column with a coil condenser.

[0031] Example 1:

[0032] Combination Figure 1-4 As shown, the present invention provides a distillation column with a coil condenser, including a feeding mechanism 100 and a preheating mechanism 200. The feeding mechanism 100 includes a column body 110, an outer shell 120 disposed on one side of the column body 110, a material flow channel 130 connecting the column body 110 and the outer shell 120, and a preheating box 140 that is attached to the inner side walls of the outer shell 120. The preheating box 140 communicates with the interior of the column body 110 through the material flow channel 130.

[0033] The preheating mechanism 200 includes a hydraulic cylinder 210 connected between the outer shell 120 and the preheating box 140, a metal plate 220 suspended at the bottom of the inner cavity of the preheating box 140, a plurality of connecting rods 230 connected between the top of the inner cavity of the outer shell 120 and the top of the metal plate 220, and a hot air pipe 240 connected between the tower body 110 and the outer shell 120.

[0034] Furthermore, the preheating box 140 is inclined, and the bottom of the inner cavity of the preheating box 140 is at the same horizontal plane as the bottom of the inner cavity of the material conveying channel 130. This structural design ensures that the raw materials in the preheating box 140 can pass smoothly through the material conveying channel 130.

[0035] Furthermore, the metal plate 220 is configured in the shape of a "﹂", and the metal plate 220 is parallel to the bottom of the inner cavity of the preheating box 140. The length and width of the metal plate 220 are the same as the length and width of the preheating box 140. The shape design of the metal plate 220 ensures that the raw material will not fall onto the top of the metal plate 220 when the feed pipe 400 is filling. The size design of the metal plate 220 allows the preheating box 140 to move with the hydraulic cylinder 210, providing conditions for efficient preheating of the raw material.

[0036] Furthermore, the multiple connecting rods 230 on the top of the metal plate 220 are equally spaced and arranged in a row. Both the metal plate 220 and the connecting rods 230 are made of metal material. The layout design of the connecting rods 230 can improve the installation firmness of the metal plate 220 inside the outer casing 120.

[0037] Furthermore, an outer frame 500 is fitted around the outside of the tower body 110. The bottom of the outer shell 120 and the condenser 320 are both connected to the top of the outer frame 500. A guardrail 600 is installed on the top of the outer frame 500. The outer frame 500 and the guardrail 600 work together to improve the stability of the tower body 110 when it is erected.

[0038] Example 2:

[0039] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, a cooling mechanism 300 is provided on the front side of the outer shell 120. The cooling mechanism 300 includes an exhaust pipe 310 connected and communicating with the outer shell 120 and a condenser 320 located on the front side of the exhaust pipe 310. The exhaust pipe 310 is located at the bottom of the preheating box 140. When the high-temperature hot air inside the outer shell 120 is discharged, it will be cooled by the condenser 320. The condenser 320 improves the environment around the tower body 110 and improves the comfort of operation.

[0040] Example 3:

[0041] Combination Figure 1 and Figure 4As shown, in the above embodiment, the top of the outer shell 120 is connected to and communicates with a feed pipe 400, and the hot air pipe 240 is located between the tower body 110 and the feed pipe 400. The feed pipe 400 is provided to provide conditions for feeding materials into the outer shell 120.

[0042] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the high-temperature gas generated by the tower body 110 is injected into the preheating box 140 through the hot gas pipe 240 to create a preheating environment for the raw materials. Then, because the metal plate 220 is located directly below the hot gas pipe 240, the metal plate 220 will be heated quickly. When the raw materials are put into the preheating box 140, the raw materials roll along the bottom of the inner cavity of the preheating box 140 towards the material conveying channel 130. At the same time, the movable end of the hydraulic cylinder 210 reciprocates to stretch the preheating box 140. Then, the metal plate 220 and the preheating box 140 work together to continuously rub and heat the surface of the raw materials, improve the preheating effect of the raw materials, reduce the moisture in the raw materials, and reduce the energy consumption of the tower body 110 during operation.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
