Description

Technical Field

[0001] This utility model relates to the field of methanol tower technology, specifically to a device for reducing the energy consumption of methanol towers. Background Technology

[0002] Methanol is flammable; its vapor can form explosive mixtures with air. It can ignite and explode upon contact with open flames or high heat. It reacts chemically with oxidizers or ignites. In a fire, heated containers pose an explosion hazard. It can spread to considerable distances at lower levels and can ignite and cause a flashback upon contact with an open flame. It decomposes into carbon monoxide and carbon dioxide upon combustion.

[0003] Application number CN202020111681.X discloses a device for reducing energy consumption in a methanol tower, including a methanol tower reboiler and other structures. This design utilizes a heater to heat the reboiler liquid, causing residual methanol in the reboiler liquid to vaporize and return to the methanol tower body through a connecting pipe. This eliminates the need to maintain a low residual methanol content in the reboiler, significantly reducing steam consumption and energy consumption. However, in practical application, the methanol vaporization rate is relatively slow, resulting in significant energy consumption by the heater. Utility Model Content

[0024] 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.

[0025] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a device for reducing the energy consumption of a methanol tower.

[0027] Example 1:

[0028] Combination Figure 1-4 As shown, the present invention provides a device for reducing the energy consumption of a methanol tower, comprising a production mechanism 100, a material extraction mechanism 200, and a reflux mechanism 300. The production mechanism 100 includes a tower body 110 and a reboiler 120 connected to and communicating with the tower body 110.

[0029] The material extraction mechanism 200 includes a discharge pump 210 connected and communicating with the tower 120 and a receiving box 220 connected and communicating with the discharge pump 210.

[0030] The reflux mechanism 300 includes a sliding cover 310 sleeved on the outside of the receiving box 220, a heating box 320 slidably sleeved on the outside of the sliding cover 310, a cylinder 330 connected between the sliding cover 310 and the heating box 320, a heating device 340 attached to the bottom of the heating box 320, two soft brushes 350 connected to the bottom of the receiving box 220, a plurality of through holes 360 opened on both sides of the receiving box 220, and a steam pipe 370 connected between the tower body 110 and the sliding cover 310.

[0031] Furthermore, the movable end of the cylinder 330 is connected to the front wall of the heating box 320, and the cylinder body of the cylinder 330 is connected to the bottom of the sliding cover 310. The connection method of the cylinder 330 enables the sliding cover 310 and the receiving box 220 to move horizontally when the movable end of the cylinder 330 extends or retracts, ensuring that the liquid in the vessel can evenly contact the bottom of the inner cavity of the heating box 320.

[0032] Furthermore, the multiple through holes 360 on both sides of the receiving box 220 are evenly spaced and arranged in a row. The through holes 360 are located inside the heating box 320. The layout design of the through holes 360 allows the liquid flowing out of the receiving box 220 to quickly and evenly cover the heating box 320, providing conditions for improving the vaporization of the liquid.

[0033] Furthermore, the receiving box 220 is connected to the interior of the heating box 320 through the through hole 360, and the interior of the heating box 320 is connected to the interior of the tower body 110 through the steam pipe 370. This structural design ensures that the steam can smoothly return to the interior of the tower body 110.

[0034] Example 2:

[0035] Combination Figure 1 and Figure 4 As shown, based on Embodiment 1, a frame 400 is installed at the bottom of the heating box 320, and the heating device 340 is installed inside the frame 400. The frame 400 can simultaneously reinforce the heating box 320 and the heating device 340, thereby improving the stability of the vaporization operation of the liquid in the reactor.

[0036] Example 3:

[0037] Combination Figure 4 As shown, in the above embodiment, two soft brushes 350 are symmetrically arranged, and their bottoms are attached to the bottom of the inner cavity of the heating box 320. The layout design of the soft brushes 350 ensures that the liquid in contact with the heating box 320 can be evenly spread.

[0038] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the discharge pump 210 pumps the liquid in the tower bottom 120 to the receiving box 220. Then, the heating device 340 and the cylinder 330 are started. The heating device 340 heats the bottom of the heating box 320 to 100 degrees Celsius. Then, the cylinder 330 moves the heating device 340 and the soft brush 350 back and forth through the sliding cover 310. The liquid in the receiving box 220 flows to the bottom of the receiving box 220 through multiple through holes 360. Then, the soft brush 350 scrapes the liquid to level it, increasing the contact area of ​​the liquid and improving the evaporation efficiency of the liquid. Then, the steam flows back to the tower body 110 through the steam pipe 370, thereby reducing the energy consumption of the heating device 340.

[0039] 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.
