Background

In the production process of chemical products, a large amount of steam is usually generated when the extraction tank cooks the substrate, and in order to avoid the situation that the steam takes away a large amount of target extract to cause the loss increase of the target extract and the situation that the concentration of the extracting solution is too high due to the evaporation of a large amount of water to further cause the dissolution efficiency of the target extract to slow down, the steam needs to be introduced into a condenser for condensation, so that the gaseous water is condensed into liquid water and flows into the extraction tank again. The existing solution is to arrange a cooling system in a steam pipeline, and has the defects of complex structure, high cost and the like.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Please refer to fig. 1, which is a partial sectional view of the steam pipe natural cooling reflux mechanism 1 provided in the present embodiment.

The steam pipe natural cooling reflux mechanism 1 comprises a steam pipe 2 extending horizontally and a condensation pipe 3 vertically arranged on the steam pipe 2. The bottom end of the condensation pipe 3 is communicated with the steam pipe 2, and the top end is open.

A core tube 31 is vertically arranged in the condensation tube 3 at an angle coaxial with the condensation tube, and the diameter of the core tube 31 is half of that of the condensation tube 3. A spiral plate 32 is spirally wound between the core tube 31 and the condensation duct 3. The spiral plate 32 is wound at an angle close to horizontal along the circumferential direction of the core tube 31.

The core tube 31 and the condensation tube 3 are both aluminum tubes, and the spiral plate 32 is an aluminum plate. The inner side and the outer side of the spiral plate 32 are welded and fixed with the outer wall of the core tube 31 and the inner wall of the condensation tube 3, respectively, so as to form a spiral channel.

The steam rises by thermal action as it passes through the steam pipe 2. Due to the greater resistance in the helical path between the spiral plates 32, it preferentially rises from the inside of the core tube 31. And the core pipe 31 exchanges heat and reduces temperature in the rising process. The spiral plate 32 plays a role of a heat radiating fin, so that heat transfer is accelerated, and cooling and condensation of steam are accelerated.

Please refer to fig. 2, which is a partial sectional view of the steam pipe natural cooling reflux mechanism 2 provided by the present invention in this embodiment.

The difference from example 1 is that: a plurality of baffles 33 are also provided within the core tube 31. The baffle 33 is an oval aluminum plate with a notch at one side edge, and the edge except the notch is welded and fixed with the inner wall of the core pipe 31. The baffle 33 and the horizontal plane form an included angle of 10 degrees inclined downwards. The baffles are arranged at intervals with reverse angles of the gaps.

The steam rises by thermal action as it passes through the steam pipe 2. Due to the greater resistance in the helical path between the spiral plates 32, it preferentially rises from the inside of the core tube 31. And the temperature is reduced by heat exchange with the baffle 33 and the core pipe 31 in the rising process. The baffle 33 also serves to extend the path of the steam, further enhancing the cooling and condensation of the steam.

Please refer to fig. 3, which is a partial sectional view of the steam pipe natural cooling reflux mechanism 2 provided by the present invention in this embodiment.

The difference from example 2 is that: cooling ducts 34 are inserted in the helical channels formed by the spiral plates 32. The cooling pipe 34 is a flexible pipe, and is folded in half and then inserted into the top end of the core tube 31 through the gap between the spiral plates 32. The cooling liquid circulating in the cooling pipeline 34 further enhances the temperature reduction and condensation of the steam.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
