Description

Technical Field

[0001] The utility model relates to a double-circulation type distillation tower. Background Art

[0002] The double-circulation distillation tower is a special distillation tower design that uses two independent circulation systems to improve distillation efficiency and product purity. This design is usually used to process mixtures with complex components, such as crude oil or chemical raw materials. The circulation system is divided into an internal circulation system and an external circulation system. The internal circulation system is often used in the distillation process of toxic substances. The circulation structure of the internal circulation system is located inside the distillation tower, and the loss caused by pipeline leakage is small, which can effectively protect the safety of personnel. The pipeline of the external circulation system is located outside the distillation tower and is generally not used for the distillation of toxic substances. However, the structure of the internal circulation system is complex and the construction cost is high.

[0003] Therefore, there is a need for a double-circulation distillation tower, which has an external circulation structure and can protect toxic substances from leaking in the event of a leak, or limit the spraying range of toxic substances to a certain extent to protect personnel safety. Utility Model Content

[0004] The purpose of the utility model is to solve the above shortcomings of the prior art and provide a double circulation distillation tower. By installing a mounting piece and a protection frame on the pipeline of the circulation system, the toxic substances can be protected from leakage when the pipeline leaks, or the spraying range of the toxic substances can be limited to a certain extent. The specific scheme is as follows:

[0005] A double-circulation distillation tower comprises a distillation tower, an upper circulation unit and a lower circulation unit, wherein the distillation tower and the circulation unit are connected via a pipeline, a plurality of mounting members are fixedly provided on the pipeline, a protective frame is clamped onto the mounting members, each mounting member comprises three connecting plates, the connecting plates are connected via shafts, the three connecting plates can be fixed into a triangular structure via bolts, the protective frame comprises a shell, a clamping unit is provided at the bottom of the shell, and a movable covering unit is provided on the upper side of the shell.

[0006] In order to increase the friction between the connecting plate and the pipeline and enhance the fixing effect, the connecting plate is provided with a notch, the notch is crescent-shaped, and fixing teeth are provided on the notch.

[0007] In order to increase the clamping and fixing effect and facilitate installation, the clamping unit includes a first clamping joint and a second clamping joint.

[0008] In order to facilitate installation, the cover unit includes a top cover, a third clamping joint and a fourth clamping joint, and the top cover is clamped on the third clamping joint and the fourth clamping joint.

[0009] For easy installation, a handle is provided on the top cover.

[0010] Beneficial effects: By installing the mounting parts and the protection frame on the pipeline of the circulation system, the mounting parts have a triangular clamping mechanism and can be easily installed. The protection frame has a snap-on structure and can be easily installed on the mounting parts. The protection frame includes a shell and a top cover, which is easy to install. At the same time, it can protect toxic substances from leaking when the pipeline leaks, or limit the spraying range of toxic substances to a certain extent to protect personnel safety.
