Detailed Implementation

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] Example:

[0027] like Figs. 1-3 As shown, an overflow degassing vessel includes a vessel cover 1, a vessel body 2, and a liquid outlet pipe 3 connected sequentially and coaxially along the liquid inlet direction. An annular overflow baffle 4 is coaxially arranged between the interior of the vessel cover 1 and the interior of the vessel body 2. The annular overflow baffle 4 and the inner wall of the vessel cover 1 form an annular flow channel. A liquid inlet 11 is provided on the vessel cover 1, and the outlet of the liquid inlet 11 is directly opposite the annular flow channel. The end of the annular overflow baffle 4 away from the inner wall of the vessel cover 1 is flush with the inner wall of the vessel body 2. The top of the annular overflow baffle 4 has an irregular annular protrusion with the axis of the vessel cover 1 as the center of rotation.

[0028] The working principle of the above technical solution is as follows:

[0029] An annular overflow baffle 4 is installed between the vessel lid 1 and the vessel body 2. The annular overflow baffle 4 and the inner wall of the vessel lid 1 form an annular flow channel. The liquid inlet 11 is directly opposite the annular flow channel. The raw liquid containing bubbles flows in from the liquid inlet 11 of the vessel lid 1 into the annular flow channel. As the amount of raw liquid flowing in increases, it gradually reaches the top of the flow channel and overflows into the vessel body 2. Since the top of the annular overflow baffle 4 is irregularly convex with the axis of the vessel lid 1 as the center of rotation, this irregular convexity can create local turbulence when the raw liquid gradually overflows, which will produce a mechanical shearing force-like effect, directly tearing the bubble film in the raw liquid. Moreover, this irregular convexity can accelerate the collision and breakage of bubbles, thereby accelerating the elimination of bubbles in the raw liquid. The raw liquid overflows into the vessel body 2 along the annular overflow baffle 4 and flows into the vessel body 2 along the inner wall of the vessel body 2, which can further increase the flow path and contact area, further promote the escape of bubbles, and improve the degassing efficiency. The degassed raw liquid flows into the outlet pipe 3 along the vessel body 2 for the next step of operation.

[0030] The vessel body 2 is conical along its axis. The inner diameter of the end of the vessel body 2 closest to the lid 1 along its axis is larger than the inner diameter of the end of the vessel body 2 furthest from the lid 1 along its axis. This long and slender structure can provide sufficient time for the raw liquid to adhere to the wall, allowing more opportunities for bubbles to separate from the raw liquid. This can further improve the degassing efficiency and ensure that the quality of the raw liquid after degassing treatment meets high standards.

[0031] The first observation window 5 is arranged on the kettle cover 1, the second observation window 6 is arranged on the side of the kettle body 2 close to the liquid outlet pipe 3 along the axis direction, the third observation window 7 is arranged on the side of the liquid outlet pipe 3 along the axis direction, and the on-line sensor 8 is arranged on the side of the kettle body 2 along the axis direction, so that the defoaming conditions of the raw liquid at different positions can be observed, the liquid inlet speed and the liquid outlet speed can be adjusted in time, and the defoaming reliability can be further improved by combining the data obtained by the on-line sensor 8 with the observation windows.

[0032] The mounting bracket 21 is arranged on the side of the kettle body 2, the kettle body 2 is fixed through the mounting bracket 21, and the safety of the defoaming process can be ensured.

[0033] The interlayer is arranged between the inner wall and the outer wall of the kettle body 2, new bubbles generated by external vibration can be eliminated through the interlayer, and the reliability of the defoaming process can be ensured.

[0034] The kettle cover 1 and the kettle body 2 are connected through flanges, and the kettle body 2 and the liquid outlet pipe 3 are connected through flanges, so that the connection reliability is high and the sealing performance is good.

[0035] The flow guide plug 9 is coaxially arranged at the center of the kettle cover 1, the flow guide plug 9 penetrates the kettle cover 1 and extends into the kettle body 2, the outer diameter of the flow guide plug 9 is smaller than the inner diameter of the annular overflow baffle 4, the annular overflow baffle 4 and the flow guide plug 9 form a very narrow flow channel through cooperation of the flow guide plug 9 and the annular overflow baffle 4, the raw liquid overflowed can flow along the outer wall of the flow guide plug 9 into the inner wall of the kettle body 2, the raw liquid overflowed at one time can be prevented from generating new bubbles, and the safety and the reliability of the defoaming can be improved.

[0036] The above-described embodiments only express the specific implementation manners of the present application, the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a plurality of modifications and improvements can be made, and these all belong to the protection scope of the present application.
