Description

Technical Field

[0001] This utility model relates to the field of separation equipment, and in particular to a spiral plate feeding structure for separation equipment. Background Technology

[0002] In industries such as energy, chemicals, petroleum, natural gas, food and beverage, and pharmaceuticals, gas-liquid separation units are crucial for ensuring production efficiency, product purity, and equipment safety. During gas-liquid separation, these units are widely used in various processes to remove droplets and impurities from gases, thereby effectively improving product quality, preventing equipment corrosion, and ensuring process stability.

[0003] Please see Figure 1 , Figure 1 The paper reveals the feeding structure of a separation device in the prior art. After the gas-liquid mixture enters from the feed inlet, the liquid will settle to the bottom in the gravitational field because the density of the liquid is much greater than that of the gas, while the gas will gather at the top, thus achieving gas-liquid separation. However, in our daily work, we have found that the feeding structure of this separation device in the prior art has low separation efficiency.

[0004] Therefore, it is necessary to provide a spiral plate feeding structure for a separation device that solves the above-mentioned technical problems. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a spiral plate feeding structure for a separation device, comprising: a separation cylinder and a feed inlet disposed on the separation cylinder, wherein a baffle mechanism is provided in the separation cylinder at a position corresponding to the feed inlet, the baffle mechanism comprising: an intermediate baffle and an upper baffle, the intermediate baffle comprising: an arc-shaped baffle portion, a first connecting baffle portion connecting one free end of the arc-shaped baffle portion to the inner wall of the separation cylinder, an inclined baffle portion connecting the other free end of the arc-shaped baffle portion, and a second connecting baffle portion connecting the inclined baffle portion to the inner wall of the separation cylinder, wherein a gas-liquid spiral flow channel is formed between the intermediate baffle and the separation cylinder, and a gas upward separation flow channel is formed in the center of the intermediate baffle, the upper baffle is disposed at the top of the gas-liquid spiral flow channel and is welded to the intermediate baffle and the inner wall of the separation cylinder respectively, and an elbow pipe penetrating the second connecting baffle is connected to the inner side of the feed inlet.

[0007] Preferably, the spiral plate feeding structure of the separation device in this utility model is further configured as follows: the elbow includes a first elbow section and a second elbow section, the first elbow section is connected to the feed inlet, the second elbow section passes through the second connecting baffle section, and the second elbow section extends downward at a 5° angle from the first elbow section.

[0008] Preferably, the spiral plate feeding structure of the separation device in this utility model is further configured such that: the inner wall of the separation cylinder is provided with an anti-impact baffle at the position of the corresponding elbow pipe.

[0009] Preferably, the spiral plate feeding structure of the separation device in this utility model is further configured such that the anti-impact baffle covers at least 25% of the circumference of the separation cylinder.

[0010] Preferably, the spiral plate feeding structure of the separation device in this utility model is further configured such that the height of the anti-impact baffle is higher than the height of the baffle mechanism.

[0011] Preferably, the spiral plate feeding structure of the separation device in this utility model is further configured such that the baffle mechanism and the anti-impact baffle are both made of stainless steel.

[0012] Preferably, the spiral plate feeding structure of the separation device in this utility model is further configured such that: the second connecting baffle portion is L-shaped, the second connecting baffle portion includes a first part connected to the inclined baffle portion and a second part for the elbow pipe to pass through, and the inclined baffle portion and the first part of the second connecting baffle portion are arranged at a 40° angle.

[0019] The spiral plate feeding structure of a separation device described in the present utility model will be further described in detail through specific embodiments below.

[0020] Refer Figure 2 And Figure 3 As shown, a spiral plate feeding structure of a separation device includes: a separation cylinder body 1 and a feed inlet 2 provided on the separation cylinder body 1. A baffle mechanism 3 is provided at a position corresponding to the feed inlet 2 inside the separation cylinder body 1. The baffle mechanism 3 includes: an intermediate baffle member 30 and an upper baffle member 31. The intermediate baffle member 30 includes: an arc baffle part 300, a first connection baffle part 301 connecting between one free end of the arc baffle part 300 and the inner wall of the separation cylinder body 1, an inclined baffle part 302 connected to the other free end of the arc baffle part 300, and a second connection baffle part 303 connecting between the inclined baffle part 302 and the inner wall of the separation cylinder body 1. A gas-liquid spiral flow channel 4 is formed between the intermediate baffle member 30 and the separation cylinder body 1. A gas upward separation flow channel 5 is formed at the center of the intermediate baffle member 30. The upper baffle member 31 is provided at the top of the gas-liquid spiral flow channel 4 and is welded to the intermediate baffle member 30 and the inner wall of the separation cylinder body 1 respectively.

[0021] The inner side of the feed inlet 2 is connected to an elbow pipe 6 that penetrates the second connecting baffle portion 303. The elbow pipe 6 includes a first elbow portion 60 and a second elbow portion 61. The first elbow portion 60 is connected to the feed inlet 2, and the second elbow portion 61 penetrates the second connecting baffle portion 303. The second elbow portion 61 extends downward at a 5° angle from the first elbow portion 60. This arrangement provides a downward spiral guidance effect for the gas-liquid mixture entering from the feed inlet 2. An anti-impact baffle 7 is provided on the inner wall of the separation cylinder 1 at the position corresponding to the elbow pipe 6. The anti-impact baffle 7 covers at least 25% of the circumference of the separation cylinder 1, thereby effectively protecting the separation cylinder 1 and extending its service life. The height of the anti-impact baffle 7 is higher than the height of the baffle mechanism 3. This arrangement avoids interference during welding of the anti-impact baffle 7. In this embodiment, both the baffle mechanism 3 and the anti-impact baffle 7 are made of stainless steel, thus possessing good corrosion resistance. The second connecting baffle portion 303 is L-shaped and includes a first part 3030 connected to the inclined baffle portion 302 and a second part 3031 through which the elbow pipe 6 passes. The inclined baffle portion 302 and the first part 3030 of the second connecting baffle portion 303 are set at a 40° angle, so that the width of the flow channel near the elbow pipe 6 in the gas-liquid spiral flow channel 4 is greater than the width of the flow channel at other positions. The advantage of this design is that the gas-liquid mixture forms a buffer after entering the gas-liquid spiral flow channel 4 from the feed port 2, thereby reducing the vibration caused by fluid impact on the equipment.

[0022] In summary, the spiral plate feeding structure of this utility model improves upon the traditional feeding structure by forming a gas-liquid spiral flow channel 4 between the intermediate baffle 30 and the separation cylinder 1. The gas-liquid spiral flow channel 4 generates strong centrifugal force, causing denser droplets to be thrown against the wall and discharged. Meanwhile, the separated gas flows out from the gas upward separation flow channel 5 in the center of the intermediate baffle 30, thereby greatly improving the efficiency of gas-liquid separation.

[0023] The above embodiments are merely illustrative of the principles and effects of this utility model, as well as some of its applications, and are not intended to limit this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
