Problems solved by technology

In the case of strong sunshine, the temperature of the vacuum buffer tank is high under direct sunlight, and the circulating cooling water in the tank cannot effectively condense the light components distilled from the top of the tower, and the residual gas phase partial pressure seriously reduces the vacuum degree of the system, thereby causing The vacuum degree of the system drops, causing the temperature of rectification and separation to rise, the separation efficiency is reduced, and even effective separation cannot be carried out.

Embodiment Construction

[0016] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] Such as figure 1 and 2 As shown, the sunshade water cooling device includes a vacuum buffer tank 1, and a sunshade cover 2 is covered outside the vacuum buffer tank 1, and a nozzle 2 connected to cooling water is arranged between the sunshade cover 2 and the vacuum buffer tank 1. Wherein, the main body of the sunshade cover 2 is a bowl-shaped bracket, and the surface of the bracket is covered with an aluminum skin with a thickness of 0.5 mm; , easy molding, corrosion resistance and good heat insulation advantages. The distance between the inner surface of the sunshade cover 2 and the outer surface of the vacuum buffer tank 1 is 20 cm, so as to reserve a certain space to ensure the heat insulation effect an...

Abstract

The invention discloses a sunshading water cooling device which comprises a vacuum buffer tank 1, wherein a sunshading sheath 2 is arranged on an outer cover of the vacuum buffer tank 1; and a spray head 3 connected with cooling water is arranged between the sunshading sheath 2 and the vacuum buffer tank 1. The surface temperature of the vacuum buffer tank can be controlled within a relatively ideal range, so that light components in the vacuum buffer tank can be condensed in time, the system vacuum degree can be improved, and higher rectification efficiency can be obtained.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a sunshade water cooling device. Background technique [0002] In the production of biodiesel, vacuum distillation is often used for the separation of intermediate products. However, vacuum rectification must add a vacuum buffer tank at the top of the rectification column to buffer the vacuum system and condense and collect the low-carbon organic matter and glycerin and other light components distilled from the top of the tower. Therefore, the temperature of the vacuum buffer tank directly affects the condensation effect of the light components; if the temperature of the vacuum buffer tank is higher than 45°C, the light components in the tank are difficult to condense, the residual pressure of the gas phase is high, and the vacuum degree decreases. Ultimately affect the efficiency of vacuum distillation. [0003] For the control of the temperature of the vacuum buffe...
