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

[0051] Example 1

[0052] See also Figures 1-2 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. A first intercepting component 21 for causing the airflow to turn for the Nth time is provided 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 causing the airflow to make the N+1th turning 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 causing the airflow to make an N+2th turn is provided at the curved portion of the third turning path 4 .

[0057] The air inlet 11, first turning path 2, second turning path 3, third turning path 4, and 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 and 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 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 utilizes 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 through 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. The liquid droplets in the airflow are gathered to the sewage outlet 13 due to the effect of gravity, and the solid particles in the airflow rebound and fall to the direction of the sewage outlet 13 for easy discharge, achieving the effect of diversion and separation; then the gas is first diverted under the guidance of the guide channel 31, and then diverted 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 while this embodiment provides three turns for the airflow, in other embodiments, a greater or lesser number of turns may be provided. Specifically, in other embodiments, a fourth or fifth turn may be provided after the third turn 4 to enhance separation effectiveness. The separator may also not include the third turn 4; that is, the gas in the airflow exits the outlet 12 after undergoing two turns and separations. In this case, a certain separation effectiveness is also achieved.

[0060] See also Figure 1In a specific implementation scenario of this embodiment, the container 1 is tubular, with an air inlet 11 and an air outlet 12 located at either end (left and right) of the container 1, respectively, and a sewage outlet 13 located on the lower sidewall of the container 1. The first intercepting member 21 is plate-shaped and connected to the inner wall of the container 1 by welding or other means. The air inlet 11 and the air outlet 12 are located on opposite sides (left and right) of the first intercepting member 21, while the air inlet 11 and the sewage outlet 13 are located on the same side (left) of the first intercepting member 21. A baffle 5, having one end closed, is connected to the first intercepting member 21 by welding or other means. The baffle 5 passes through the first intercepting member 21, with the closed end facing the air inlet 11 and protruding from the side of the first intercepting member 21, and the other end communicating with the air inlet 11. Several guide channels 31 are arranged on the lower portion of the sidewall of the baffle 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 deflector tube 5 , and the upper portion of the inner wall of the deflector tube 5 has the function of intercepting and turning the airflow.

[0061] To ensure a good separation effect, a guide cone 51 is provided at the closed end of the deflector tube 5, with the sharp end of the guide cone 51 facing the air inlet 11. Multiple deflector tubes 5 are provided, and the multiple deflector tubes 5 and guide cones 51 are evenly distributed on the first intercepting member 21. The guide cones 51 evenly disperse the airflow. After colliding with the first intercepting member 21, the evenly dispersed airflow enters each deflector tube 5 through the corresponding guide channel 31. This avoids the problem of uneven separation effect caused by airflow deviation. In other embodiments, the size and number of the guide cones 51 and the deflector tubes 5 are not limited.

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

[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 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 adopted, 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 scale mainly gathers in the lower left part of the first intercepting component 21, that is, the scale is unevenly distributed, which also brings challenges to the cleaning effect. When there are too many local scales, it is difficult to ensure effective cleaning.

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

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

[0070] Secondly, the separator further comprises a cleaning mechanism connected to the deflector tube 5 . 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. 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 is rotatably connected to the outer wall of the deflector tube 5 via a bearing.

[0074] The scraper 62 is provided 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] A counterweight component 63 is disposed at the bottom of the circumferential side surface of the connecting ring 61. The counterweight component 63 is arcuate, with its inner side welded to the outer wall of the connecting ring 61. The counterweight component 63 is used to maintain the posture of the scraper 62 during the rotation of the first intercepting member 21, so that the scraper 62 can clean multiple areas on the left side of the first intercepting member 21.

[0076] Under the gravity of the weight component 63, the scraper 62 can maintain Figure 3 In the vertical state shown, as the first intercepting member 21 slowly rotates one circle, the first intercepting member 21 rotates one circle relative to the scraper 62, and the scraper 62 contacts the circular area on the left side of the first intercepting member 21, thereby scraping off the scale in the circular area. Because multiple baffles 5 are distributed in a circular array around each baffle 5, the scraper 62 will not interfere with other components. In addition, because the first intercepting member 21 rotates, scale is no longer concentrated in the lower left portion of the first intercepting member 21, and the scale is more evenly distributed. During the rotation of the first intercepting member 21, the scraper 62 itself is less likely to deflect due to excessive force, and the scraper 62 has a more stable scraping effect on scale.

[0077] It should be noted that, in this embodiment, the scraper 62 and the counterweight component 63 are spaced apart 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 horizontally arranged push plate 71, which 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. 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 shown) is an obtuse angle. Thus, 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 toward the drain outlet 13 to prevent these objects from remaining in the container 1.

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

[0081] Step S1: The air flow is diverted 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 scale located at the lower part of the inner wall of the container 1 toward the sewage outlet 13.

[0084] When rotating the first intercepting member 21, the first intercepting member 21 can be rotated slowly at a certain speed throughout the entire operation, 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. This helps to save energy, reduce wear, and extend the service life.

[0085] While effectively separating liquid droplets and solid particles in the gas, this method can also effectively clean the left side of the first intercepting component 21 and the inner wall of the container 1, making it difficult for bacteria to grow in the container 1 and for odor to be generated.

[0086] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. The embodiments and features of the embodiments of this application may be combined arbitrarily without conflict. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
