When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0043] Example 1

[0044] Reference Figure 1-Figure 3, provides a waste incineration waste gas treatment device, including a dust box 100, wherein a filter component 200 is provided inside the dust box 100; the filter component 200 includes a fixed plate 201 arranged in the dust box 100, a through hole 202 opened on the fixed plate 201, and a dust filter assembly 203 arranged in the through hole 202;

[0045] The fixed plate 201 is fixed in the dust box 100, and a plurality of groups of through openings 202 are opened on the fixed plate 201, and the plurality of groups of through openings 202 are equidistantly distributed on the fixed plate 201, and the through openings 202 are circular, and a dust filter assembly 203 is provided in the through opening 202, and the dust filter assembly 203 is sealed and connected with the through opening 202, so that the exhaust gas can only pass through the dust filter assembly 203 before entering the top of the fixed plate 201 and being discharged. The exhaust gas after the incineration of garbage enters the dust box 100 for treatment, and the dust filter assembly 203 filters it, and the treated gas is discharged again to reduce the air pollution caused by harmful substances in the incineration exhaust gas.

[0046] Furthermore, the outside of the dust box 100 is provided with an air inlet 101 and an air outlet 102 which are connected to each other, and a dust exhaust port 103 which is arranged at the bottom of the dust box 100; wherein the air inlet 101 is located below the fixing plate 201, and the air outlet 102 is arranged above the fixing plate 201;

[0047] The dust box 100 is located below the fixed plate 201 and is provided with an air inlet 101, which is connected to the inside of the dust box 100. The dust-containing exhaust gas enters the dust box 100 through the air inlet 101. The dust box 100 is located above the fixed plate 201 and is provided with an air outlet 102, which is also connected to the inside of the dust box 100. After the gas filtered by the dust filter assembly 203 enters above the fixed plate 201, it is discharged from the air outlet 102. A dust exhaust port 103 is provided at the bottom of the dust box 100, and the dust filtered by the cloth bag 203b can be discharged through the dust exhaust port 103.

[0048] Furthermore, the dust filter assembly 203 includes a rubber tube 203a disposed in the opening 202, and a cloth bag 203b disposed at the bottom end of the rubber tube 203a; the rubber tube 203a is fixedly disposed on the inner wall of the opening 202, so that the rubber tube 203a is fixedly disposed on the fixing plate 201, the rubber tube 203a is located below the fixing plate 201, and the cloth bag 203b is fixedly disposed on the inner wall of the bottom end of the rubber tube 203a, and the rubber tube 203a can be connected to the two by sewing, hot pressing, bonding, etc. The cloth bag 203b is in the shape of a cylinder with a closed bottom. The cloth bag 203b filters the dusty gas, and the dust is blocked on the outside of the cloth bag 203b. The rubber tube 203a is in the shape of a hollow cylinder as a whole, so that the gas can enter the top of the fixed plate 201. The rubber tube 203a can be made of a relatively hard material to prevent the wind from causing the cloth bag 203b to swing irregularly and greatly. The cross section of the middle position of the rubber tube 203a is wavy, and this shape gives it a larger longitudinal elastic range;

[0049] By arranging the rubber tube 203a between the cloth bag 203b and the fixed plate 201, during the dust filtering process, the wind force of the dust-laden gas causes the cloth bag 203b to swing slightly, so that the dust on its surface is shaken off. During the operation of the equipment, it can have a self-cleaning effect, reduce the frequency of shutdown and backblowing, and improve the working efficiency of the equipment. At the same time, during the backblowing cleaning process, the blowing device can also be controlled to increase or decrease, thereby causing the cloth bag 203b to shake, thereby assisting the backblowing device in cleaning the cloth bag 203b.

[0050] Example 2

[0051] In the above embodiment, when the back-blowing device blows dust, the high-pressure wind is very easy to spread around, and then it is difficult to blow into the bag 203b in a concentrated manner, so that the cleaning effect of the dust on the bag 203b is poor;

[0052] Reference Figure 1-Figure 6 , this embodiment is different from the first embodiment in that: it also includes a guide component 300, which includes a fixing component 301 arranged in the through opening 202, and a guide bucket 302 arranged on the fixing component 301; wherein the fixing component 301 extends into the cloth bag 203b;

[0053] A fixing component 301 is provided in the opening 202, and a guide bucket 302 is provided on the top of the fixing component 301. The guide bucket 302 is in an inverted cone shape, and the top of the guide bucket 302 corresponds to the nozzle of the backblowing device. The nozzle can be located above the guide bucket 302, or inside the guide bucket 302, so that the backblowing high-pressure wind enters the guide bucket 302 and is guided into the fixing component 301. Since the fixing component 301 is located in the cloth bag 203b, the backblowing gas can better enter the cloth bag 203b, thereby improving the backblowing cleaning effect of the cloth bag 203b.

[0054] Furthermore, the fixing assembly 301 includes a connecting rod 301a disposed in the through hole 202, a long tube 301b disposed on the connecting rod 301a, and a vent hole 301c opened on the long tube 301b; wherein a sliding cylinder 301d is disposed at the bottom end of the cloth bag 203b, a guide bucket 302 is disposed at the top end of the long tube 301b, and the long tube 301b extends into the cloth bag 203b;

[0055] A plurality of connecting rods 301a are fixedly arranged on the inner wall of the opening 202 above the rubber tube 203a, and a long tube 301b is fixedly arranged between the plurality of connecting rods 301a. The long tube 301b is a round tube with two ends passing through. The long tube 301b extends into the cloth bag 203b. The long tube 301b is located at the center of the cloth bag 203b. The bottom of the guide bucket 302 is fixedly connected to the top of the long tube 301b. The guide bucket 302 is connected to the long tube 301b. The portion of the long tube 301b located in the cloth bag 203b has a plurality of vent holes 301c, so that the back-blowing gas Can be evenly distributed in the cloth bag 203b, the inner bottom of the cloth bag 203b is fixedly provided with a sliding cylinder 301d, and the sliding cylinder 301d is slidingly connected to the bottom end of the long tube 301b, and the cloth bag 203b is limited by the sliding connection between the sliding cylinder 301d and the long tube 301b, so that the cloth bag 203b can only slide up and down, preventing the cloth bag 203b from shaking left and right during the operation of the equipment, reducing the wear of the rubber cylinder 203a, and the length of the sliding cylinder 301d is greater than the elastic stroke of the rubber cylinder 203a, so as to prevent the sliding cylinder 301d from detaching from the long tube 301b;

[0056] Since the guide bucket 302 corresponds to the nozzle of the back-blowing device, when the nozzle back-blows, the high-pressure wind is guided by the guide bucket 302 into the long tube 301b, and after passing through the vent hole 301c, the high-pressure wind blows onto the inner wall of the cloth bag 203b, causing the dust on the outer wall of the cloth bag 203b to fall off and clean it, thereby improving the cleaning effect of the back-blowing setting.

[0057] The rest of the structure is the same as that of Example 1.

[0058] Example 3

[0059] In the above embodiment, the rubber tube 203a enables the cloth bag 203b to have a self-cleaning effect of shaking off dust, but the shaking amplitude is limited and the self-cleaning effect is very small;

[0060] Reference Figure 1-Figure 10 , this embodiment is different from the above embodiment in that: it also includes a cleaning component 400, which includes a sliding component 401 arranged on the long tube 301b, an elastic member 402 arranged on the sliding component 401, a guide component 403 arranged on the cloth bag 203b, and a reset component 404 arranged between the long tube 301b and the guide component 403; wherein the sliding component 401 is movably connected to the guide component 403, and the elastic member 402 is connected to the bottom end of the long tube 301b;

[0061] A sliding assembly 401 is provided on the outside of the long tube 301b, and an elastic member 402 is arranged in contact with the inner wall of the cloth bag 203b. A guide assembly 403 cooperating with the sliding assembly 401 is provided on the inner wall of the cloth bag 203b. Since the supporting force of the rubber cylinder 203a is limited, when a certain amount of dust is stained on the outside of the cloth bag 203b, its own weight will increase, and under the limit of the sliding cylinder 301d, it will slide vertically downward, and the cloth bag 203b will drive the guide assembly 403 to move during the movement, and the guide assembly 403 will cause the sliding assembly 401 to slide laterally after the movement. During the movement of the sliding assembly 401 in the guide assembly 403, after the elastic member 402 is driven away from the inner wall of the cloth bag 203b, it will reset instantly due to its own elasticity, so that the elastic member 402 hits the inner wall of the cloth bag 203b, so that the dust on the outside of the cloth bag 203b is vibrated and falls, thereby improving the self-cleaning effect of the cloth bag 203b, and further reducing the frequency of equipment shutdown and backwashing;

[0062] After the cloth bag 203b is cleaned, due to the reduction of its own weight, the reset component 404 pushes the cloth bag 203b to reset, and at this time, the sliding component 401 drives the elastic member 402 to reset, so as to prepare for the next use of the cleaning component 400.

[0063] Furthermore, the sliding assembly 401 includes a limiting cylinder 401a disposed outside the long tube 301b, a sliding plate 401b disposed in the limiting cylinder 401a, and a guide column 401c disposed at the end of the sliding plate 401b; wherein the guide column 401c is connected to the guide assembly 403;

[0064] The limiting cylinder 401a is fixedly arranged on the outside of the long tube 301b, and multiple groups of limiting cylinders 401a are arranged at equal distances. A cavity is arranged in the limiting cylinder 401a, and the limiting cylinder 401a is slidably connected to the sliding plate 401b through the cavity. A guide column 401c is fixedly arranged at the end of the sliding plate 401b, and the elastic member 402 is connected to the bottom of the sliding plate 401b. When the weight of the cloth bag 203b increases and slides downward, the guide assembly 403 is on the guide column 401c. 1c guides the sliding plate 401b to slide in the limiting cylinder 401a, and during the sliding process, the end of the elastic member 402 is driven to move, so that the end of the elastic member 402 is away from the cloth bag 203b and is released instantly. After being released, the elastic member 402 is reset due to its own elasticity, so that it hits the inner wall of the cloth bag 203b, causing the cloth bag 203b to vibrate and the dust on the outside of the cloth bag 203b to fall off, thereby achieving the self-cleaning effect of the cloth bag 203b.

[0065] Furthermore, the elastic member 402 is mainly composed of a circular arc plate 402a and inclined plates 402b disposed at both ends of the circular arc plate 402a; wherein the ends of the two sets of inclined plates 402b are respectively connected to the sliding plate 401b and the long tube 301b, and the limiting cylinder 401a is provided with a connecting groove 401d corresponding to the inclined plate 402b;

[0066] The elastic member 402 itself has a certain toughness, so that it can automatically reset after being driven by the sliding plate 401b. The arc plate 402a is a vertical long plate with an arc, and the arc fits the inner wall of the cloth bag 203b. The two ends of the arc plate 402a are connected with inclined plates 402b. The ends of the two sets of inclined plates 402b are fixedly connected to the bottom of the sliding plate 401b and the outer bottom end of the long tube 301b. The bottom of the limit tube 401a is provided with a connecting groove 401d, which is connected The connecting groove 401d does not pass through the end of the limiting cylinder 401a, so that the elastic member 402 can pass through the connecting groove 401d and be fixedly connected to the bottom of the sliding plate 401b, and the connection between the elastic member 402 and the sliding plate 401b can limit it and prevent the sliding plate 401b from separating from the limiting cylinder 401a. In the initial state, the arc plate 402a is pressed against the inner wall of the cloth bag 203b, so that it can hit the inner wall of the cloth bag 203b when it is instantly reset.

[0067] Furthermore, the guide assembly 403 includes a fixing ring 403a disposed on the inner wall of the cloth bag 203b, a side plate 403b disposed on the fixing ring 403a, and a guide groove 403c opened on the side plate 403b; wherein the guide column 401c is plugged into the guide groove 403c, and the reset assembly 404 is disposed on the top of the side plate 403b;

[0068] A fixing ring 403a is fixedly provided on the inner wall of the cloth bag 203b near the top, and multiple groups of side plates 403b are fixedly provided on the inner wall of the fixing ring 403a, and the side plates 403b are arranged in groups of two, and the multiple groups of side plates 403b are arranged at equal distances, and there is a certain distance between the side plates 403b in the same group, so that the limiting cylinder 401a and the sliding plate 401b can move between the two side plates 403b, and the two side plates 403b have guide grooves 403c on the opposite sides, and the two ends of the guide column 401c are inserted into the guide grooves 403c, and the reset assembly 404 is arranged on the top of the multiple groups of side plates 403b;

[0069] A short transverse portion 403c-1 is provided at the bottom end of the guide groove 403c, and an oblique portion 403c-2 is provided on the side of the short transverse portion 403c-1 close to the long tube 301b. The oblique portion 403c-2 is inclined with the end close to the long tube 301b. When there is a small amount of dust with a certain weight on the outside of the bag 203b, the side plate 403b is driven to move downward, and the guide column 401c can move from the short transverse portion 403c-1 to the oblique portion 403c-2. At the same time, a slope 403c-7 is provided on the top wall of the connection between the short transverse portion 403c-1 and the oblique portion 403c-2, so that the guide column 401c can better enter the oblique portion 403c-2. Since the sliding part is limited by the limiting cylinder 401a and can only slide horizontally, when the guide column 401c moves in the oblique part 1 403c-2, the sliding plate 401b slides toward the long tube 301b, and then drives the arc plate 402a away from the inner wall of the cloth bag 203b. The top of the oblique part 1 403c-2 is connected with the longitudinal part 1. When the guide column 401c moves in the longitudinal part 1, the cloth bag 203b continues to increase in weight and descend, and the top of the longitudinal part 1 is connected with the long transverse part 403c-4. At the moment when the guide column 401c corresponds to the long transverse part 403c-4, the elastic member 402 is released and reset, and then hits the inner wall of the cloth bag 203b, causing the dust on the outer side to fall off after the vibration;

[0070] The end of the long horizontal portion 403c-4 is connected to the second oblique portion 403c-5, and the second oblique portion 403c-5 is inclined with the end thereof close to the inner wall of the cloth bag 203b. The bottom end of the second oblique portion 403c-5 is connected to the second longitudinal portion 403c-6, and the bottom end of the second longitudinal portion 403c-6 is connected to the end of the short horizontal portion 403c-1. When the arc plate 402a pops out and hits the inner wall of the cloth bag 203b, the weight of the cloth bag 203b is reduced, and the cloth bag 203b is instantly reset under the drive of the rubber tube 203a and the reset component 404, so that the guide column 401c passes through the second oblique portion 403c-5 and the second longitudinal portion 403c-6 and returns to the short horizontal portion 403c-1, so that the cloth bag 203b can cycle the above actions to achieve a self-cleaning effect;

[0071] The short horizontal portion 403c-1 is close to one end of the long tube 301b, i.e., the starting position 403c-8 of the guide column 401c and the connection between the long horizontal portion 403c-4 and the second oblique portion 403c-5 are on the same vertical line. Fig.10As shown, after the elastic member 402 bounces and resets, the guide column 401c can smoothly enter the oblique portion 403c-5, while ensuring that the elastic member 402 can accurately hit the cloth bag 203b. Based on this arrangement, the oblique portion 403c-5 and the longitudinal portion 403c-6 are arranged. Due to the inclined arrangement of the oblique portion 403c-5, after the guide column 401c enters the short horizontal portion 403c-1 and is pulled back to the starting position 403c-8 by the elastic member 402, it no longer corresponds to the longitudinal portion 403c-6 and can accurately enter the oblique portion 1 403c-2 from the starting position, thereby ensuring the moving path of the guide column 401c and enabling the device to repeat actions.

[0072] Furthermore, the reset assembly 404 includes a ring 404a disposed outside the long tube 301b, a connecting frame 404b disposed outside the ring 404a, and a spring 404c disposed outside the long tube 301b; wherein the connecting frame 404b is connected to the side plate 403b, and the two ends of the spring 404c are respectively in contact with the ring 404a and the limiting cylinder 401a;

[0073] A circular ring 404a is sleeved on the outside of the long tube 301b, which is located above the side plate 403b. The circular ring 404a can move on the outside of the long tube 301b. A connecting frame 404b is fixedly provided on the outside of the circular ring 404a. The bottom end of the connecting frame 404b is fixedly connected to the top of the side plate 403b. A spring 404c is sleeved on the outside of the long tube 301b. Both ends of the spring 404c are in conflict with the circular ring 404a and the limiting cylinder 401a. When the cloth bag 203b moves downward, the circular ring 404a is driven to move downward through the connecting frame 404b. Since the limiting cylinder 401a is fixed, the circular ring 404a squeezes the spring 404c for compression. After the cloth bag 203b vibrates and reduces its weight, the spring 404c loses its squeezing force and pushes the cloth bag 203b to reset through the circular ring 404a.

[0074] The rest of the structure is the same as that of Example 2.

[0075] Operation process: In the initial state, the spring 404c is in an extended state, the arc plate 402a of the elastic member 402 is pressed against the inner wall of the cloth bag 203b, and the guide column 401c is located at the starting position 403c-8, i.e., the end of the short horizontal portion 403c-1;

[0076] After the equipment is turned on, the dust-containing gas enters the dust collecting box 100 from the air inlet 101, and the cloth bag 203b filters the dust in the gas. The dust adheres to the outside of the cloth bag 203b, increasing the dead weight of the cloth bag 203b. After the cloth bag 203b becomes heavier, it slides vertically downward under the limit of the sliding cylinder 301d, and the guide column 401c enters the oblique part 1 403c-2 from the short horizontal part 403c-1, so that the sliding plate 401b slides laterally in the limiting cylinder 401a. At the same time, the sliding plate 401b drives the elastic member 402 away from the inner wall of the cloth bag 203b. During the operation of the equipment, the cloth bag 203b continues to become heavier and moves downward, and the spring 404c is squeezed and contracted. When the guide column 401c passes through the longitudinal part 1 and corresponds to the long horizontal part 403c-4 , the elastic member 402 is reset instantly due to its own toughness. When the elastic member 402 is reset, the arc plate 402a partially hits the inner wall of the cloth bag 203b, and the cloth bag 203b vibrates to cause the dust outside to fall. At the same time, the cloth bag 203b becomes lighter after being cleaned, and the spring 404c and the rubber tube 203a drive the reset to move upward and reset. The guide column 401c returns to the short horizontal portion 403c-1 after passing through the oblique portion 403c-5 and the longitudinal portion 403c-6, and returns to the starting position 403c-8 driven by the elastic member 402, so that the guide column 401c can move cyclically in the guide groove 403c, so that the cloth bag 203b can repeatedly clean itself, and the cleaned dust is discharged from the dust exhaust port 103 at the bottom of the dust collecting box 100;

[0077] By setting the cleaning component 400, the dust on the outside of the bag 203b can be cleaned, thereby improving the self-cleaning effect of the bag 203b, further reducing the frequency of shutdown for cleaning, improving the efficiency of the equipment in treating waste gas, and also ensuring the filtering effect of the bag 203b on waste gas.
