[0050] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0051] Example 1

[0052] See also Figure 1~Figure 2 This embodiment provides a separator for separating liquid droplets and solid particles from an air flow. The separator includes a container 1, a first turning path 2, a second turning path 3 and a third turning path 4.

[0053] The container 1 has an air inlet 11 , an air outlet 12 and a sewage outlet 13 .

[0054] The first turning path 2 has a curved track, and a first intercepting component 21 for making the airflow turn for the Nth time is arranged at the curved portion of the first turning path 2, where N≥1.

[0055] The second turning path 3 has a curved track, and a guide channel 31 for making the airflow turn for the N+1th time is provided at the curved portion of the second turning path 3 .

[0056] The third turning path 4 has a curved track, and a second intercepting component for making the airflow turn for the N+2th time is provided at the curved portion of the third turning path 4 .

[0057] The air inlet 11, the first turning path 2, the second turning path 3, the third turning path 4 and the air outlet 12 are connected in sequence, and the sewage outlet 13 is located below the first turning path 2. The bends of the first turning path 2, the second turning path 3 and the third turning path 4 are all located above the sewage outlet 13 and are connected to the sewage outlet 13.

[0058] The density of liquid droplets and solid particles is significantly greater than that of gas, and the inertial force of gas movement is significantly different from that of the other two phases, that is, gas is easy to turn, while liquid droplets and solid particles are difficult to turn. This embodiment uses the above principle, and the air inlet 11 is connected to the airflow with a certain pressure and temperature. After the airflow enters the container 1 from the air inlet 11, it flows along the first turning path 2 and collides with the first intercepting component 21. The gas in the airflow turns to enter the second turning path 3, and the liquid droplets in the airflow converge to the sewage outlet 13 due to the gravity effect. The solid particles in the airflow rebound and fall to the direction of the sewage outlet 13 for easy sewage discharge, which has the effect of turning and separation; then the gas turns under the guidance of the guide channel 31, and then turns under the interception of the second intercepting component to separate the liquid droplets and solid particles in the gas.

[0059] It should be noted that this embodiment designs three turns for the airflow, and in other embodiments, more or fewer turns may be designed; specifically, in other embodiments, a fourth turn path, a fifth turn path, etc. may be provided after the third turn path 4 to improve the separation effect. The separator may not include the third turn path 4, that is, the gas in the airflow flows out from the gas outlet 12 after two turns and separations, and in this case, a certain separation effect is also achieved.

[0060] See also Figure 1In a specific implementation scenario of the present embodiment, the container 1 is tubular, the air inlet 11 and the air outlet 12 are respectively located at the two ends (left end and right end) of the container 1, and the sewage outlet 13 is located on the lower side wall of the container 1. The first intercepting member 21 is plate-shaped, which is connected to the inner wall of the container 1 by welding or the like, the air inlet 11 and the air outlet 12 are located on the opposite sides (left and right sides) of the first intercepting member 21, and the air inlet 11 and the sewage outlet 13 are located on the same side (left side) of the first intercepting member 21. The first intercepting member 21 is connected with a baffle tube 5 with one end closed by welding or the like, the baffle tube 5 passes through the first intercepting member 21, the closed end of the baffle tube 5 faces the air inlet 11 and protrudes from the side of the first intercepting member 21, and the other end is connected to the air inlet 11, and a plurality of guide channels 31 are arranged at the lower part of the side wall of the baffle tube 5 protruding from the first intercepting member 21. The second intercepting component in the third turning path 4 includes the upper portion of the inner wall of the baffle tube 5 , and the upper portion of the inner wall of the baffle tube 5 has the function of intercepting and turning the airflow.

[0061] In order to ensure a good separation effect, a guide cone 51 is provided at the closed end of the baffle tube 5, and the sharp end of the guide cone 51 faces the air inlet 11. There are multiple baffle tubes 5, and the multiple baffle tubes 5 and guide cones 51 are evenly distributed on the first interception component 21. The airflow is evenly dispersed by the guide cone 51, and the evenly dispersed airflow collides with the first interception component 21 and enters each baffle tube 5 through the corresponding guide channel 31. In this way, the problem of uneven separation effect caused by airflow deviation can be avoided. In other embodiments, the size and number of the guide cone 51 and the baffle tube 5 are not limited.

[0062] In this embodiment, the guide channel 31 is arranged along the radial direction of the baffle tube 5 so that the air inlet direction of the baffle tube 5 is perpendicular to the air inlet direction of the air inlet 11, and it is difficult for droplets and solid particles to enter the baffle tube 5, resulting in a better separation effect.

[0063] A step 52 or a reduced diameter portion is provided on the inner wall of one end of the deflector tube 5 connected to the air inlet 11 for reducing its inner diameter, so as to increase a predetermined slope at the outlet of the deflector tube 5, so that a small amount of escaping droplets adhere to the inner wall of the deflector tube 5 and flow back to the guide channel 31, and finally converge into the sewage pipe, thereby improving the separation and sewage discharge effects.

[0064] In this embodiment, the first intercepting component 21 is coaxially arranged with the container 1, so that the left side of the first intercepting component 21 can be perpendicular to the air intake direction of the air inlet 11, so that the airflow directly hits the first intercepting component 21, which is beneficial to improve the separation effect.

[0065] Example 2

[0066] Since both the liquid droplets and the solid particles are in contact with the left side of the first intercepting component 21 , after long-term use, the left side of the first intercepting component 21 (especially the lower left side) is prone to scale and bacteria growth, causing odor in the gas discharged from the air outlet 12 .

[0067] In order to deal with the above situation, the inventors considered setting up a movable cleaning component to clean the left side of the first intercepting component 21 on the basis of Example 1. However, there are many deflection tubes 5 on the first intercepting component 21 that block the movement of the cleaning component. If flushing is used, although cleaning can be achieved, it will affect the separation effect of the separator, which has caused trouble for the inventors; in addition, after the droplets in the air flow collide with the first intercepting component 21, they will carry some solid particles and flow downward along the left side of the first intercepting component 21. The scaling materials are mainly gathered in the lower left part of the first intercepting component 21, that is, the scaling materials are unevenly distributed, which also brings challenges to the cleaning effect. When there are too many local scaling materials, it is difficult to ensure effective cleaning.

[0068] Based on the above content, this embodiment makes the following improvements to the separator in Embodiment 1.

[0069] First, see Figure 1~Figure 5 In this embodiment, part of the structure of the separator in Example 1 is adjusted: a plurality of (6 or 3) deflector tubes 5 are distributed in a circular array around each deflector tube 5; the circumferential side surface of the first intercepting component 21 is rotatably sealed to the inner wall of the container 1.

[0070] Secondly, the separator further comprises a cleaning mechanism connected to the deflector tube 5 , and during the rotation of the first intercepting component 21 , the posture of the cleaning mechanism remains unchanged to clean multiple areas on the left side of the first intercepting component 21 .

[0071] The cleaning mechanism includes a driving source (not shown in the figure), a connecting ring 61 , a scraper 62 and a weight component 63 .

[0072] The driving source is used to rotate the first intercepting member 21. The specific implementation of the driving source is not limited, and the driving source is, for example, disposed on the right side of the first intercepting member 21.

[0073] The connecting ring 61 is located on the left side of the first intercepting component 21 , and the connecting ring 61 is rotatably connected to the outer wall of the deflector tube 5 via a bearing.

[0074] The scraper 62 is disposed on the top of the circumferential side surface of the connecting ring 61 , and the scraper 62 is in sliding contact with the left side of the first intercepting member 21 .

[0075] The weight component 63 is arranged at the bottom of the circumferential side surface of the connecting ring 61. The weight component 63 is arc-shaped, and its inner side is welded to the outer wall of the connecting ring 61. The weight component 63 is used to keep the posture of the scraper 62 unchanged during the rotation of the first intercepting component 21, so as to clean multiple areas on the left side of the first intercepting component 21 through the scraper 62.

[0076] Under the gravity of the weight component 63, the scraper 62 can maintain Figure 3 In the vertical state shown, during the process of slowly rotating the first intercepting component 21 by one circle, the first intercepting component 21 rotates by one circle relative to the scraper 62, and the scraper 62 contacts the circular area on the left side of the first intercepting component 21, thereby scraping off the scale in the circular area. Since a plurality of baffle tubes 5 are distributed in a circular array around each baffle tube 5, the scraper 62 will not interfere with other components. In addition, since the first intercepting component 21 rotates, the scale is no longer gathered at the lower left side of the first intercepting component 21, and the distribution of the scale is more uniform. During the rotation of the first intercepting component 21, the scraper 62 itself is not prone to deflection due to excessive force, and the scraper 62 has a more stable scraping effect on the scale.

[0077] It should be noted that, in the present embodiment, the scraper 62 and the weight component 63 are arranged at intervals on the circumferential side surface of the connecting ring 61, and the angle between the two is 180 degrees. In other embodiments, the angle between the two can be adjusted appropriately.

[0078] The separator also includes a slag pushing mechanism, which is arranged near the lower left side of the first intercepting component 21 and is used to move the liquid droplets, solid particles and scraped scale located at the lower inner wall of the container 1 to the sewage outlet 13.

[0079] In this embodiment, the slag pushing mechanism includes a push plate 71 arranged transversely, the push plate 71 is connected to the bottom of the counterweight component 63 on the plurality of baffle tubes 5 (the baffle tubes 5 in the outermost circle) closest to the inner wall of the container 1, and one end of the push plate 71 extends above the sewage outlet 13; in the direction from the first intercepting component 21 to the air inlet 11, the width of the push plate 71 ( Figure 5 In the state shown, the dimension of the push plate 71 in the left-right direction gradually decreases, and the right side of the push plate 71 ( Figure 5 The included angle between the deflector tube 5 and the first intercepting component 21 (in the left and right directions as shown) is an obtuse angle, so that when the deflector tube 5 carries the push plate 71 and moves to the lower part of the inner wall of the container 1 and briefly contacts the inner wall of the container 1, the push plate 71 can push the droplets, solid particles and scraped scale to move to the drain outlet 13 to prevent these objects from remaining in the container 1.

[0080] Thirdly, see Figure 1~Figure 5This embodiment provides a separation method, which uses the above separator, and the separation method includes the following steps:

[0081] Step S1, making the gas flow turn multiple times to separate liquid droplets and solid particles in the gas.

[0082] The airflow is turned multiple times through the first turning path 2 , the second turning path 3 and the third turning path 4 .

[0083] Step S2, rotate the first intercepting component 21; during the rotation of the first intercepting component 21, the posture of the cleaning mechanism remains unchanged, and multiple areas on the left side of the first intercepting component 21 are cleaned. At the same time, the slag pushing mechanism is used to move the droplets, solid particles and scaling located at the lower part of the inner wall of the container 1 toward the sewage outlet 13.

[0084] When the first intercepting member 21 is rotated, the first intercepting member 21 can be rotated slowly at a certain speed throughout the entire process, or the first intercepting member 21 can be rotated intermittently. When the first intercepting member 21 is rotated intermittently, for example, the first intercepting member 21 can be rotated a certain number of times only after the scale reaches a certain thickness, which helps to save energy, reduce wear and extend the service life.

[0085] This method can effectively separate liquid droplets and solid particles in the gas and can also effectively clean the left side of the first intercepting component 21 and the inner wall of the container 1, so that bacteria are not easy to grow in the container 1 and odor is not easy to be generated.

[0086] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
