DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 As shown, a backwashable gas-liquid-solid three-phase integrated separation device comprises: a shell 1, the interior of the shell 1 is divided into a gas-liquid-solid three-phase zone 101, a gas-liquid two-phase zone 102 and a gas phase zone 103 by a filter element assembly support plate 4 and a partition system 11, a filter element assembly support plate 4 is arranged in the gas-liquid-solid three-phase zone 101, and a plurality of filter element assemblies are installed in an array on the filter element assembly support plate 4; a feed port 8 is arranged on the outer wall of the shell 1, a gas-liquid-solid three-phase mixture enters the gas-liquid-solid three-phase zone 101 through the feed port 8, a gas-liquid two-phase mixture passes through the filter element assembly and enters the gas-liquid two-phase zone 102, and solid materials are intercepted by the filter element assembly in the gas-liquid-solid three-phase zone 101, and are discharged through a slag discharge port 12 at a later stage.

[0032] Among them, a clear liquid outlet 14 is arranged on the outer wall of the shell 1, one end of which is arranged in the gas-liquid two-phase zone 102, and the clear liquid outlet 14 is mainly used to discharge the clear liquid in the gas-liquid two-phase zone 102; a clean gas outlet 10 is arranged at the top of the gas phase zone 103, and the clean gas outlet 10 is used to discharge the gas after the liquid mist is removed.

[0033] A backwash port 15 is provided on the outer wall of the housing 1, one end of the feed port 8 is connected to the gas-liquid-solid three-phase region 101, and one end of the backwash port 15 is connected to the gas-liquid two-phase region 102. When the resistance of the entire separation system reaches a critical value, that is, when the filter element assembly 5 is blocked, gas or liquid is transported to the gas-liquid two-phase region 102 through the backwash port 15. Under the direct pressure of the gas or liquid, the gas or liquid enters the filter element assembly 5 through the upper end opening of the filter element assembly 5 and is discharged from the circumferential outer side of the filter element assembly 5. When the gas or liquid is discharged, the solid materials attached to the filter element assembly 5 are flushed, and it is no longer necessary to remove the filter element assembly 5 as a whole from the equipment and then clean it separately, which effectively improves the cleaning efficiency of the filter element assembly 5.

[0034] In addition, you can choose to first transport liquid into the gas-liquid two-phase area 102 through the backwash port 15, and when the liquid overflows the filter element assembly, then transport gas into the gas-liquid two-phase area 102. Under the action of gas pressure, the liquid enters the filter element assembly 5 through the opening at the upper end of the filter element assembly 5, and is discharged from the circumferential outer side of the filter element assembly 5. When the liquid is discharged, it flushes the solid material attached to the filter element assembly 5, which can save a certain amount of cleaning liquid.

[0035] During operation, the gas-liquid-solid three-phase mixture enters the middle of the gas-liquid-solid three-phase zone 101 through the feed inlet 8, and the liquid level of the gas-liquid-solid three-phase mixture rises. When the liquid level overflows the filter element assembly 5, the solid material is intercepted by the filter element assembly in the gas-liquid-solid three-phase zone 101, and the gas-liquid two-phase mixture passes through the filter element assembly into the interior of the filter element assembly 5, and enters the gas-liquid two-phase zone 102 through the opening on the filter element assembly support plate 4; when the liquid level of the gas-liquid two-phase mixture entering the gas-liquid two-phase zone 102 overflows the clear liquid outlet 14, the clear liquid flows out through the clear liquid outlet 14, and the remaining gas continues to rise with the liquid mist, and the gas is discharged from the clean gas outlet 10, completing the separation of the gas-liquid-solid three-phase mixture, and the liquid mist in the gas gathers into droplets in the labyrinth baffle blade assembly 6, and flows into the clear liquid again through the downcomer 13, so as to realize the secondary collection of the liquefied clear liquid and improve the discharge rate of the clear liquid.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, a plurality of labyrinth baffle blade assemblies 6 are arranged in the gas-liquid two-phase region 102, and the labyrinth baffle blade assembly 6 includes: a liquid accumulation frame 602, and a plurality of labyrinth baffle blades 601 are inserted into the end surface of the liquid accumulation frame 602, so the liquid accumulation frame 602 has the function of positioning and fixing the labyrinth baffle blades 601. After the gas enters the labyrinth baffle blade assembly 6, the liquid mist entrained in the gas collides with the gas on the labyrinth baffle blades 601 and gathers into droplets, and the gas is discharged from the clean gas outlet 10, and the droplets converge into the rectangular liquid accumulation frame 602 under the action of gravity, so that the gas and liquid mist are effectively separated, and the liquefied clear liquid is further collected through the clear liquid outlet 14.

[0037] It should be noted that the labyrinth baffle blades 601 in the labyrinth baffle blade assembly 6 can be selected in different sizes and quantities to adjust the volume of liquid separation, and the accuracy of liquid separation can be adjusted by selecting different sizes of the labyrinth baffle blades 601 on the labyrinth baffle blade assembly 6. The smaller the size of the labyrinth baffle blades 601, the more labyrinth baffle blades 601 are required, that is, the greater the density of the labyrinth baffle blades 601 in the liquid accumulation frame 602, the higher the accuracy of liquid separation. On the contrary, the larger the size of the labyrinth baffle blades 601, the fewer labyrinth baffle blades 601 are required, that is, the smaller the density of the labyrinth baffle blades 601 in the liquid accumulation frame 602, the lower the accuracy of liquid separation. It should be noted that the labyrinth baffle blade assembly 6 is maintenance-free and only requires a one-time investment, saving most of the maintenance and repair costs.

[0038] Optionally, the liquid accumulation frame 602 is formed by welding a cofferdam plate around the bottom end of the labyrinth baffle blade 601, and the bottom surface of the liquid accumulation frame 602 is designed to be closed, and the end surface of the liquid accumulation frame 602 is provided with a receiving port, and a plurality of labyrinth baffle blades 601 are inserted into the receiving port to form a labyrinth baffle blade assembly. The above-mentioned cofferdam plate can also be connected and formed by other methods around the bottom end of the labyrinth baffle blade 601. As long as a fixed state can be formed, it belongs to the protection scope of this solution, and this application does not limit the fixing method.

[0039] In one embodiment of the utility model, the side wall of the liquid accumulation frame 602 is covered on the bottom end of a plurality of labyrinth-type deflection blades 601, and the bottom surface of the liquid accumulation frame 602 is connected to the downcomer 13, which is used to drain the clear liquid in the liquid accumulation frame 602 into the gas-liquid two-phase zone under the action of gravity.

[0040] In a specific embodiment, the number of labyrinth-type baffle blade assemblies 6 corresponds to that of downcomers 13, the bottom of the downcomers 13 is connected to the gas-liquid two-phase region 102, the liquid droplets are drained into the clear liquid through the downcomers 13, and the liquefied clear liquid is collected for a second time through the clear liquid outlet 14, which can further improve the discharge rate of the clear liquid.

[0041] In one embodiment of the utility model, the liquid accumulation frame 602 is preferably rectangular, and a plurality of labyrinth-type deflection blades 601 are arranged in an array in the rectangular liquid accumulation frame 602. The sides of the plurality of rectangular liquid accumulation frames 602 are connected to each other, and at the same time, the bottom surface of the liquid accumulation frame 602 is connected to the partition system 11, which can isolate the gas-liquid two-phase zone 102 and the gas phase zone 103 from each other. The gas in the gas-liquid two-phase zone 102 can only enter the gas phase zone 103 through the labyrinth-type deflection blades 601, and the overall structural design is more reasonable.

[0042] In one embodiment of the utility model, the bottom of the liquid accumulation frame 602 can be set to an inverted cone shape to ensure that the droplets falling from the labyrinth deflection blades 601 are discharged from the downcomer 13 as much as possible, avoiding the accumulation of clear liquid in the liquid accumulation frame 602, and further improving the clear liquid discharge rate.

[0043] like Figure 5 As shown, the filter element assembly includes: end plates 506 symmetrically arranged at both ends of the filter element assembly skeleton 504, and filter material 505 is coated on the circumferential outer side of the filter element assembly skeleton 504. The filter material 505 is used to block the solid materials in the gas-liquid-solid three-phase mixture outside the filter element assembly skeleton 504. The filter material 505 and the filter element assembly skeleton 504 are formed into an integral structure by winding or sintering, which helps to improve the quality of the overall filter element assembly 5. The filter element assembly 5 is not easy to be damaged and can be used repeatedly. On the other hand, by forming the filter material 505 and the filter element assembly skeleton 504 into an integral structure by winding or sintering, it is also possible to avoid the appearance of a gap at the junction of the filter element assembly 5 and the filter material 505, thereby effectively improving the filtering accuracy of the filter element assembly 5.

[0044] Among them, a clip 502 is provided at one end of the filter element assembly skeleton 504, and the clip 502 is connected to the filter element assembly support plate 4. The filter element assembly 5 is fixed on the filter element assembly support plate 4 through the clip 502 and the end plate 506, wherein the filter element assembly 5 is installed on the filter element assembly support plate 4 from the lower part of the gas-liquid-solid three-phase region 101. Compared with the filter element assembly 5 and the filter element assembly support plate 4 of the traditional integrated structure, after the filter element assembly 5 is damaged, it is only necessary to disassemble the equipment flange 3 and remove the filter element assembly 5 alone for maintenance, and it is not necessary to remove the filter element assembly 5 and the filter element assembly support plate 4 as a whole, which increases the convenience during maintenance.

[0045] It should be noted that the backwashing cycle of solid cleaning can be flexibly adjusted according to the size and number of the filter element assembly 5 on the filter plate to ensure that the filtering speed can always be guaranteed when the filter element assembly 5 is working. At the same time, the precision of the filter material 505 on the filter element assembly 5 is selected to adjust the precision of solid separation.

[0046] According to factors such as the temperature and corrosion characteristics of the medium, the material of the labyrinth baffle blade 601 and the filter material 505 can be selected to be non-metallic or metal. When the filter material 505 is made of non-metallic material, polypropylene, polyethylene, nylon, absorbent cotton, glass fiber and other materials can be further selected according to the precision requirements of solid separation; when the filter material 505 is made of metal material, metal filter screen, sintered filter screen, sintered filter felt, sintered powder and the like can be selected according to the precision requirements of solid separation.

[0047] A pull rod 503 is set through the axis position of the filter element assembly skeleton 504, and both ends of the pull rod 503 are threadedly connected to the locking nuts 501. By rotating the two locking nuts 501 and moving them closer to each other, the two end plates 506 can be stably fixed on both sides of the filter element assembly skeleton 504.

[0048] A conical head 2 is provided at the bottom of the shell 1, and the conical head 2 is flange-connected to the shell 1, wherein the conical head 2 is in an inverted cone shape as a whole, and the conical head 2 is connected to the bottom of the shell 1 by fastening bolts, and a slag discharge port 12 is provided at the bottom of the conical head 2. By installing the slag discharge port 12 at the bottom of the conical head 2, it is more conducive to the discharge of solid materials and solid residues, and avoids solid materials and solid residues from remaining inside the shell 1.

[0049] A liquid level detection system 7 is arranged on the outer wall of the shell 1, and the liquid level height of the clear liquid is monitored by the liquid level detection system 7, so as to automatically adjust the feeding speed of the gas-liquid-solid three-phase mixture material and the discharging speed of the clear liquid. When the height of the clear liquid in the gas-liquid two-phase zone 102 is higher than the specified height, the filtering pressure of the filter element assembly 5 is relatively large, and it is necessary to slow down the entry speed of the gas-liquid-solid three-phase mixture material; when the height of the clear liquid in the gas-liquid two-phase zone 102 is lower than the specified height, the filtering pressure of the filter element assembly 5 is relatively small, and the entry speed of the gas-liquid-solid three-phase mixture material can be appropriately increased.

[0050] The upper opening of the liquid level detection system 7 is located in the gas-liquid two-phase region 102, and the lower opening of the liquid level detection system 7 is located in the gas-liquid-solid three-phase region 101. The upper opening of the liquid level detection system 7 is higher than the clear liquid outlet 14, and the lower opening of the liquid level detection system 7 is lower than the feed port 8, so as to ensure that the liquid level detection system 7 can always detect the liquid level of the clear liquid in the gas-liquid two-phase region 102.

[0051] In one embodiment of the utility model, an impact baffle 9 is installed at the position of the feed port 8, and the impact baffle 9 is installed inside the shell 1. The impact baffle 9 is mainly used to reduce the impact force when the gas-liquid-solid three-phase mixed material enters the gas-liquid-solid three-phase zone 101, to avoid the gas-liquid-solid three-phase mixed material directly impacting the filter element assembly 5, and to protect the filter element assembly 5. It can also reduce the impact of the mixed material inside the gas-liquid-solid three-phase zone 101, avoid stirring the precipitated material, and improve the filtration efficiency of the filter element assembly 5.

[0052] Among them, when the filter element assembly 5 and the filter element assembly support plate 4 are an integrated structure, if the filter element assembly 5 is damaged, the equipment flange 3 must be disassembled before the filter element assembly 5 and the filter element assembly support plate 4 are removed as a whole, which is extremely inconvenient. By detachably arranging multiple filter element assemblies 5 on the filter element assembly support plate 4, when a filter element assembly 5 is damaged, it is only necessary to take out the damaged filter element assembly 5 separately, and there is no need to remove the filter element assembly 5 and the filter element assembly support plate 4 as a whole, which effectively improves the convenience of maintenance.

[0053] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0054] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
