It combines the style of polyester with the advantages of cotton fabrics, such as polyester-cotton fabric.

[0015] The present invention also provides a method for using the above-mentioned waste gas filtering and purification device for chemical fiber blended yarn production, comprising the following steps:

[0016] Step 1: The exhaust gas enters the interior of the spray tower through the exhaust pipe for initial filtration to eliminate pollutants in the exhaust gas. Then, it enters the interior of the filter through the connecting pipe to remove large particles of impurities. Then, the exhaust gas is guided by the inlet pipe through the guide plate and the flow equalization network at the air inlet to enter the interior of the purification box. It is fully in contact with the electrode and adsorbs particulate matter. After the ionization and adsorption process, most of the pollutants are removed. The purified gas is discharged from the exhaust pipe of the purifier and then enters the subsequent treatment process.

[0017] Step 2: When the exhaust gas enters the purifier too fast, the second motor is started to drive the threaded rod to rotate, so that the threaded block moves along the inner wall of the installation groove and moves along the threaded rod, pushing the rotating plate to rotate, and the rotating plate pushes the first baffle to move. The second baffle and the movable plate are pushed to move by the action of the connecting rod, so that the first baffle and the second baffle are moved to the side of the guide hole, completely exposing the guide hole.

According to the flow direction of the airflow and the angle to be adjusted, the airflow is guided to diffuse evenly in all directions, changing the flow direction and speed distribution of the airflow to prevent the airflow from directly rushing to a certain area and affecting the contact between the exhaust gas and the electrode;

[0019] The second electric telescopic rod is no longer fixed, and the second electric telescopic rod is started to move upward and is no longer connected with the guide plate and the flow balancing net. The mounting plate, the first motor, the rotating rod, the first electric telescopic rod, the second electric telescopic rod, the first transmission wheel, the second transmission wheel and the belt are driven to move to the side of the flow balancing net at the same time, exposing the moving opening, and the guide plate and the flow balancing net are driven by the pulling block to move the movable rod, so that the movable rod is separated from the plug block, so that it moves out of the outside of the purifier through the moving opening, and the guide plate and the flow balancing net are rotated, and the guide plate and the flow balancing net are placed inside the purifier, so that they are fixed in their original positions, and the side originally close to the electrode faces the air inlet to prevent the guide plate and the flow balancing net from diverting the exhaust gas for a long time, which is damaged and affects the use.

[0020] The beneficial effects of the present invention are:

[0021] (1) The present invention can adjust the size of the guide hole by moving the first baffle, the second baffle and the movable plate, and by rotating the guide plate and the flow equalizing net simultaneously, the airflow is guided to diffuse evenly in all directions according to the flow direction of the airflow and the angle to be adjusted, thereby changing the flow direction and velocity distribution of the airflow, avoiding the airflow from directly rushing to a certain area, preventing the airflow velocity from being too fast and the airflow from being unevenly distributed when the exhaust gas enters the purifier, thereby improving the contact effect between the particulate matter and the electrode, and improving the purification efficiency and the exhaust gas filtration effect;

[0022] (2) The present invention removes the guide plate and the flow equalizing net through the movable port to change their direction, thereby preventing the guide plate and the flow equalizing net from being damaged by guiding the exhaust gas for a long time and affecting their use. At the same time, the second electric push rod, the tightening block and the limiting rod improve the stability of the guide plate and the flow equalizing net and the first electric telescopic rod and the second electric telescopic rod, thereby improving the stability of the guide plate and the flow equalizing net installed inside the purifier and facilitating their use.

[0034] The exhaust gas treatment structure includes a spray tower 2, a connecting pipe 3, a filter 4, an air intake pipe, a purifier 5, an exhaust pipe 6, a guide plate 7, a flow equalizing network 8, and an adjustment structure. The spray tower 2 is provided with a filter 4 at one end of the connecting pipe 3, an air intake pipe is fixedly installed on one side of the filter 4, a purifier 5 is fixedly installed on one end of the air intake pipe, an exhaust pipe 6 is fixedly installed on one end of the purifier 5, a guide plate 7 is provided inside the purifier 5, a flow equalizing network 8 is provided on one side of the guide plate 7, a mounting groove is provided inside the guide plate 7, and an adjustment structure is provided inside the mounting groove. A movable port is provided at the top of the purifier 5, and a movable groove is provided on the inner wall of the movable port and located on the inner wall of the top of the purifier 5. A first electric push rod 10 is fixedly installed on the inner wall of one side of the movable groove, a mounting plate 11 is fixedly installed on one side of the first electric push rod 10, and a connecting assembly is provided at the bottom of the mounting plate 11;

[0035] The connecting assembly includes a first motor 12, a rotating rod 13, a first electric telescopic rod 14, a first transmission wheel 15, a belt 16, a second transmission wheel 17, and a second electric telescopic rod 18; the first motor 12 is fixedly installed on the bottom of the mounting plate 11, and the output end of the first motor 12 is transmission-connected to the rotating rod 13, the first electric telescopic rod 14 is fixedly installed on the bottom of the rotating rod 13, one end of the first electric telescopic rod 14 is plugged into the top of the guide plate 7, one end of the rotating rod 13 is fixedly installed on the first transmission wheel 15, the outer side of the first transmission wheel 15 is transmission-connected to the belt 16, and the inner wall of one side of the belt 16 is transmission-connected to the second transmission wheel 17, the second electric telescopic rod 18 is fixedly installed in the middle of the second transmission wheel 17, and one end of the second electric telescopic rod 18 is plugged into the top of the flow equalizing network 8.

[0036] The exhaust gas enters the interior of the spray tower 2 through the exhaust pipe 1 for primary filtration to remove pollutants in the exhaust gas, and then enters the interior of the filter 4 through the connecting pipe 3 to remove large particles of impurities from the exhaust gas, and then enters the purifier 5 through the air inlet pipe to be guided through the guide plate 7 and the flow equalization network 8, fully contacting with the electrode 19 and adsorbing particulate matter. After the ionization and adsorption process, most of the pollutants are removed, and the purified gas is discharged from the exhaust pipe 6 of the purifier 5 and then enters the subsequent treatment process. When the exhaust gas enters the purifier 5 too fast, the size of the guide hole is adjusted by adjusting the structure 9, and the length of the guide plate 7 is increased, so that the exhaust gas can pass through the filter 4. When passing through the guide hole, it will be dispersed into multiple small airflows to prevent the airflow from bypassing the guide plate 7, thereby achieving a more even distribution. The first motor 12 then drives the rotating rod 13 and the first electric telescopic rod 14 to rotate, and the transmission action of the first transmission wheel 15, the second transmission wheel 17 and the belt 16 drives the second electric telescopic rod 18 to rotate, so that the guide plate 7 and the flow equalizing network 8 rotate at the same time. According to the flow direction of the airflow and the angle that needs to be adjusted, the airflow is guided to diffuse evenly in all directions, changing the flow direction and speed distribution of the airflow, avoiding the airflow directly rushing to a certain area, affecting the contact between the exhaust gas and the electrode 19, and facilitating the improvement of the exhaust gas purification effect.

[0037] like Figures 4 and 5 As shown, an electrode 19 is provided inside the purifier 5, and an air inlet is provided on the side of the purifier 5 close to the air inlet pipe. The guide plate 7 and the flow equalizing net 8 are both located on the side of the electrode 19, and are located at the air inlet. The guide plate 7 and the flow equalizing net 8 are both provided with guide holes, and the guide holes are distributed in a linear array. The adjustment structure 9 is symmetrically arranged around the center of the guide plate 7.

[0038] The electrode 19 inside the purifier 5 adsorbs particulate matter in the exhaust gas to improve the exhaust gas purification effect. The symmetrically arranged adjustment structure 9 can adjust the guide holes on the guide plate 7 so that the exhaust gas can be guided at the air inlet through the guide plate 7 and the flow equalizing network 8, so that the exhaust gas is evenly distributed and enters the interior of the purifier 5. The particulate matter in the exhaust gas is adsorbed by the electrode 19 inside the purifier 5 to improve the exhaust gas purification effect.

[0039] like Figures 5 and 6 As shown, a movable rod 20 is fixedly installed at the bottom of the guide plate 7 and the flow equalizing net 8. A socket is provided at the bottom of the movable rod 20 and located on the inner wall of the bottom of the purifier 5. An insert block 21 is rotatably connected inside the socket, and the movable rod 20 is plugged into the insert block 21.

[0040] By connecting the movable rod 20 and the plug block 21, the positions of the guide plate 7 and the flow equalizing net 8 can be limited inside the purifier 5, and when the guide plate 7 and the flow equalizing net 8 rotate, the connection between the movable rod 20 and the plug block 21 allows the plug block 21 to rotate inside the socket, thereby improving the stability of the rotation of the guide plate 7 and the flow equalizing net 8.

[0041] like Figure 5 、 Figure 7 As shown, the adjustment structure 9 includes a second motor 901, and the output end of the second motor 901 is transmission-connected with a threaded rod 902, and one end of the threaded rod 902 is threadedly connected to a threaded block 903, both sides of the threaded block 903 are slidingly connected to the inner wall of the mounting groove, and both sides of the bottom of the threaded block 903 are hinged with a rotating plate 904, and one end of the rotating plate 904 is hinged with a first baffle 905, and a plurality of second baffles 906 are arranged on one side of the first baffle 905, and movable openings are opened on both sides of the guide plate 7, and a movable plate 907 is movably connected inside the movable opening. The first baffle 905 and the second baffle 906, between the second baffle 906, and the second baffle 906 and the movable plate 907 are all connected by a connecting rod 908.

[0042] By starting the second motor 901, the threaded rod 902 is driven to rotate along the inner wall of the installation groove, and the threaded block 903 slides along the inner wall of the installation groove, and the threaded block 903 moves along the direction of the threaded rod 902, pushing the rotating plate 904 to deflect, so that the rotating plate 904 pushes the first baffle 905 to move, and through the action of the connecting rod 908, the second baffle 906 and the movable plate 907 move at the same time, so that the first baffle 905 and the second baffle 906 move to the side of the guide hole, completely exposing the guide hole, and at the same time, the movable plate 907 moves to the side of the guide plate 7 through the movable port, and the length of the guide plate 7 is increased by the movable plate 907, so that the airflow can enter the interior of the purifier 5 evenly through the guide holes on the guide plate 7 and the flow equalizing network 8, so that the exhaust gas can fully contact with the electrode 19 and absorb particulate matter in the exhaust gas, thereby improving the purification efficiency.

[0043] like Figure 7 As shown, one side of the second motor 901 is fixedly installed on the inner wall of the installation groove, and the first baffle 905, the second baffle 906, and the movable plate 907 are all slidably connected to the inner wall of the installation groove, and they are all located in the middle of the guide hole on the guide plate 7. One end of the movable plate 907 extends through the movable opening to one side of the guide plate 7, and the connecting rod 908 is located on the upper and lower sides of the guide hole.

[0044] When the rotating plate 904 is deflected, it pushes the first baffle 905 to move along the inner wall of the installation groove. Through the action of the connecting rod 908, the second baffle 906 and the movable plate 907 are also moved along the inner wall of the installation groove. When the threaded block 903 moves to the threaded rod 902 and away from the end of the second motor 901, the first baffle 905 and the second baffle 906 are moved to one side of the guide hole, no longer blocking the guide hole, thereby increasing the flow of airflow and preventing the exhaust gas from flowing too fast and entering the interior of the purifier 5 with uneven distribution, resulting in a high content of particulate matter in the exhaust gas finally discharged, thereby affecting the effect of exhaust gas filtration and purification.

[0045] like Figure 1 、 Figure 2 、 Figure 5 As shown, a protective door 22 is provided inside the moving port and at the top of the purifier 5, the mounting plate 11 is located in the middle of the moving port and at the bottom of the protective door 22, pull blocks 23 are fixedly installed at both ends of the bottom of the guide plate 7 and the flow equalizing net 8, and fixed structures 24 are provided on both sides of the mounting plate 11 and at the top of the guide plate 7 and the flow equalizing net 8.

[0046] The protective door 22 is opened so that the fixing structure 24 no longer fixes the mounting plate 11 and the first electric telescopic rod 14 and the second electric telescopic rod 18. The mounting plate 11 is driven to move by the first electric push rod 10, and the first motor 12, the rotating rod 13, the first electric telescopic rod 14, the second electric telescopic rod 18, the first transmission wheel 15, the second transmission wheel 17 and the belt 16 are simultaneously moved to the side of the flow equalizing network 8, exposing the movable opening. The guide plate 7 and the flow equalizing network 8 are driven to move by the pull block 23, so that the movable rod 20 is separated from the insert block 21, so that it is moved out of the outside of the purifier 5 through the movable opening, the guide plate 7 and the flow equalizing network 8 are rotated, and the guide plate 7 and the flow equalizing network 8 are placed inside the purifier 5 and fixed in their original position, and the side originally close to the electrode 19 is facing the air inlet to prevent the guide plate 7 and the flow equalizing network 8 from being damaged by diverting the exhaust gas for a long time. After both sides of the guide plate 7 and the flow equalizing network 8 have been used, they can be taken out through the movable opening and replaced, thereby improving the use effect.

[0047] like Figure 5 、 Figure 8As shown, the fixing structure 24 includes a fixing plate 241, and two second electric push rods 242 are fixedly installed on one side of the fixing plate 241, and a tightening block 243 is fixedly installed on one side of the second electric push rod 242 located below, and a limiting rod 244 is fixedly installed on one side of the tightening block 243. The bottom of the fixing plate 241 is fixedly installed with the guide plate 7 and the top of the flow equalizing network 8 respectively. The fixing plate 241 and the second electric push rod 242, the tightening block 243 and the limiting rod 244 are all located on both sides of the first electric telescopic rod 14 and the second electric telescopic rod 18. One end of the first electric telescopic rod 14 and the second electric telescopic rod 18 is provided with a limiting groove, and the limiting rod 244 is plugged into the limiting groove. Fixed grooves are provided on both sides of the mounting plate 11, and one end of the second electric push rod 242 above the tightening block 243 is plugged into the fixing groove.

[0048] The fixing plate 241 facilitates the installation of the two second electric push rods 242, and the second electric push rod 242 above is plugged into the fixing groove to facilitate fixing the mounting plate 11, so that the first motor 12, the rotating rod 13, the first electric telescopic rod 14, and the second electric telescopic rod 18 connected to the bottom of the mounting plate 11 remain stable. The tightening block 243 is pressed against the outer sides of the first electric telescopic rod 14 and the second electric telescopic rod 18 and plugged into the limiting groove through the limiting rod 244, so that the first electric telescopic rod 14 and the second electric telescopic rod 18 are respectively stably connected to the guide plate 7 and the flow balancing network 8, so that when the first motor 12 rotates, the rotating rod 13 and the first electric telescopic rod 14 are driven to rotate, and the second electric telescopic rod 18 is driven to rotate through the transmission action of the first transmission wheel 15, the second transmission wheel 17 and the belt 16, so that the guide plate 7 and the flow balancing network 8 rotate at the same time, the angle and position are adjusted, and the uniformity of airflow distribution is improved.

[0049] The present invention also provides a method for using the above-mentioned waste gas filtering and purification device for chemical fiber blended yarn production, comprising the following steps:

[0050] Step 1: The exhaust gas enters the interior of the spray tower 2 through the exhaust pipe 1 for initial filtration to remove pollutants in the exhaust gas. The exhaust gas then enters the interior of the filter 4 through the connecting pipe 3 to remove large particles of impurities. The exhaust gas is then guided by the air inlet pipe through the guide plate 7 and the flow equalization net 8 at the air inlet to enter the interior of the purifier 5. The exhaust gas is fully in contact with the electrode 19 and adsorbs particulate matter. After the ionization and adsorption process, most of the pollutants are removed. The purified gas is discharged from the exhaust pipe 6 of the purifier 5 and then enters the subsequent treatment process.

[0051] Step 2: When the exhaust gas enters the purifier 5 too quickly, the second motor 901 is started to drive the threaded rod 902 to rotate, so that the threaded block 903 moves along the inner wall of the installation groove and moves along the threaded rod 902, pushing the rotating plate 904 to rotate. The rotating plate 904 pushes the first baffle 905 to move, and the second baffle 906 and the movable plate 907 are pushed to move by the action of the connecting rod 908, so that the first baffle 905 and the second baffle 906 are moved to the side of the guide hole, completely exposing the guide hole. At the same time, the movable plate 907 moves to the side of the guide plate 7 through the movable opening, and the length of the guide plate 7 is increased by the movable plate 907;

[0052] Step 3: The first motor 12 drives the rotating rod 13 and the first electric telescopic rod 14 to rotate, and the first transmission wheel 15, the second transmission wheel 17 and the belt 16 drive the second electric telescopic rod 18 to rotate, thereby causing the guide plate 7 and the flow equalizing net 8 to rotate simultaneously. According to the flow direction of the airflow and the angle to be adjusted, the airflow is guided to diffuse evenly in all directions, changing the flow direction and speed distribution of the airflow, and preventing the airflow from directly rushing to a certain area, affecting the contact between the exhaust gas and the electrode 19;

[0053] Step 4: Open the protective door 22, and retract the second electric push rod 242 to separate the upper second electric push rod 242 from the fixed groove, and no longer fix the mounting plate 11, so that the lower second electric telescopic rod 18 drives the pressing block 243 and the limiting rod 244 to move, so that the limiting rod 244 is separated from the limiting groove, and the second electric telescopic rod 18 is no longer fixed. Start the second electric telescopic rod 18 to move upward and no longer connect with the guide plate 7 and the flow-sharing network 8, and drive the mounting plate 11, the first motor 12, the rotating rod 13, the first electric telescopic rod 14, and the second electric telescopic rod 18 through the first electric push rod 10. 18. The first transmission wheel 15, the second transmission wheel 17 and the belt 16 are simultaneously moved to the side of the flow-equalizing net 8, exposing the movable port. The guide plate 7 and the flow-equalizing net 8 are driven by the pull block 23 to drive the movable rod 20 to move, so that the movable rod 20 is separated from the plug block 21, so that it moves out of the outside of the purifier 5 through the movable port. The guide plate 7 and the flow-equalizing net 8 are rotated and placed inside the purifier 5 to fix them in their original positions. The side originally close to the electrode 19 is faced to the air inlet to prevent the guide plate 7 and the flow-equalizing net 8 from being damaged by diverting the exhaust gas for a long time, which affects the use.

[0054] Working principle: When in use, the exhaust gas enters the interior of the spray tower 2 through the exhaust pipe 1 for initial filtration to remove pollutants in the exhaust gas, and then enters the interior of the filter 4 through the connecting pipe 3 to remove large particles of impurities from the exhaust gas. Then, the exhaust gas is guided by the air inlet pipe through the guide plate 7 and the flow equalizing net 8 at the air inlet, so that the exhaust gas enters the interior of the purifier 5, fully contacts the electrode 19 and adsorbs particulate matter. After the ionization and adsorption process, most of the pollutants are removed, and the purified gas is discharged from the exhaust pipe 6 of the purifier 5 and enters the subsequent treatment process. When the exhaust gas enters the purifier 5 too fast, the second motor 901 is started to drive the threaded rod 902 to rotate, so that the threaded block 903 moves along the inner wall of the mounting groove and moves along the threaded rod 902, pushing the rotating plate 904 to rotate, and the rotating plate 904 pushes the first baffle 905 moves, and the second baffle 906 and the movable plate 907 are pushed to move by the action of the connecting rod 908, so that the first baffle 905 and the second baffle 906 move to the side of the guide hole, and the guide hole is completely exposed. At the same time, the movable plate 907 moves to the side of the guide plate 7 through the movable opening, and the length of the guide plate 7 is increased by the movable plate 907. Then, the first motor 12 drives the rotating rod 13 and the first electric telescopic rod 14 to rotate, and the transmission action of the first transmission wheel 15, the second transmission wheel 17 and the belt 16 drives the second electric telescopic rod 18 to rotate, so that the guide plate 7 and the flow equalizing network 8 rotate at the same time, and according to the flow direction of the airflow and the angle to be adjusted, the airflow is guided to diffuse evenly in all directions, the flow direction and speed distribution of the airflow are changed, and the airflow is prevented from directly rushing to a certain area, affecting the contact between the exhaust gas and the electrode 19.

[0055] The protective door 22 is opened, and the second electric push rod 242 is retracted, so that the upper second electric push rod 242 is separated from the fixing groove and the mounting plate 11 is no longer fixed. The second electric telescopic rod 18 below drives the pressing block 243 and the limiting rod 244 to move, so that the limiting rod 244 is separated from the limiting groove and the second electric telescopic rod 18 is no longer fixed. The second electric telescopic rod 18 is started to move upward and is no longer connected to the guide plate 7 and the flow equalizing network 8. The first electric push rod 10 drives the mounting plate 11, the first motor 12, the rotating rod 13, the first electric telescopic rod 14, and the second electric telescopic rod 18. , the first transmission wheel 15, the second transmission wheel 17 and the belt 16 are moved to the side of the flow equalizing net 8 at the same time, exposing the movable port, and the guide plate 7 and the flow equalizing net 8 are driven by the pull block 23 to drive the movable rod 20 to move, so that the movable rod 20 is separated from the plug block 21, and is moved out of the outside of the purifier 5 through the movable port, and the guide plate 7 and the flow equalizing net 8 are rotated, and the guide plate 7 and the flow equalizing net 8 are placed inside the purifier 5, fixed in their original position, and the side originally close to the electrode 19 is faced to the air inlet to prevent the guide plate 7 and the flow equalizing net 8 from being damaged by diverting the exhaust gas for a long time, thereby affecting use.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
