Problems solved by technology

In order to save energy and recycle heat energy, there is a structure in the prior art that can collect the heat of the heavy component buffer tank through the heat transfer medium, and use this heat to preheat the feed pipe. In this structure, the heavy component buffer tank passes through two The two ends of the pipe and the feed pipe with the preheating chamber are connected separately, and the heat collected is easy to be lost in the pipe, especially when the heavy component buffer tank and the molecular distillation equipment are far away, the preheating effect is negligible and needs to be improved urgently

Embodiment 1

[0029] see figure 1 The disclosed molecular distillation equipment uses a feed pipe to spiral to a preheating device.

[0030] The feed pipe spiral preheating device for molecular distillation equipment includes: an inner spacer 2 matched with the outer wall of the feed pipe 1 and a hollow cylindrical outer protective tube 3 ringed outside the inner spacer 2;

[0031] see figure 2 , image 3 , Figure 4 and Figure 5 , the inner spacer, the key component in this embodiment, is mainly used to restrict the path of the heat-conducting medium.

[0032] The inner spacer 2 includes: two separately arranged end rings, two partitions bridged between the two end rings, and two helical plates bridged between the two partitions.

[0033] see figure 2 , the two end rings are tightly sleeved on the feed pipe 1 respectively and are respectively the first end ring 4 and the second end ring 5; the first end ring 4 and the second end ring 5 are used for connecting with the feed The pi...

Abstract

The invention provides a specific structure of a feed pipe spiral preheating device for molecular distillation equipment. According to the technical scheme, through the structural setting of an internal isolation frame and an external protection pipe, and optimized improvement of the internal isolation frame structure, the route of a heat-conducting medium flowing through the spiral preheating device is optimized, so that the heat-conducting medium can flow through the outer side wall of the feed pipe regularly, and uniform preheating of the whole outer side wall of the feed pipe can be ensured.

Description

technical field [0001] The present disclosure generally relates to the technical field related to molecular distillation, and in particular to a helical preheating device for a feeding tube of molecular distillation equipment. Background technique [0002] Molecular distillation, also known as short-path distillation, is a relatively new liquid-liquid separation technology that has not been widely used in industrial production. Its application can solve a large number of problems that cannot be solved by conventional distillation technology. A complete set of molecular distillation equipment mainly includes: molecular evaporator, degassing system, feeding system, heating system, cooling vacuum system and control system, etc. [0003] In a specific application, molecular distillation equipment is used to connect the feed pipe and the heavy component surge tank. In order to save energy and recycle heat energy, there is a structure in the prior art that can collect the heat of...
