Description

Technical Field

[0001] The present invention relates to the technical field of pulse dust removal, and in particular to an intelligent pulse dust removal device and a use method thereof. Background Art

[0002] Pulse dust removal equipment is a device specially designed to treat waste gas with high dust content. Pulse dust removal equipment is mainly composed of filter bag chamber, air bag and air supply system. Pulse dust removal equipment uses the filtering effect of filter bag to intercept dust (dust) in the waste gas and form a filter cake on the outside of the filter bag. Then, when the resistance of the filter bag reaches a certain value, the air supply system starts working and applies pulse airflow to the filter bag to recoil clean the filter bag, thereby realizing intelligent automatic cleaning.

[0003] During the self-cleaning process, the existing pulse dust removal equipment simply applies pulse airflow (high-pressure air) into the filter bag. However, the degree of adhesion of dust attached to the outside of the filter bag varies. When the dust with a low degree of adhesion is cleaned, the pulse airflow will be discharged from the cleaned area and will not be able to continue to act on the place where dust still remains, resulting in poor cleaning effect. The number of subsequent cleaning operations required for the filter bag will also increase simultaneously, thereby reducing the working efficiency of the dust removal equipment.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. It is also explained here that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them, and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0019] like Figure 1-Figure 4 As shown in the figure, an embodiment of the present invention proposes an intelligent pulse dust removal device to solve the problem that the existing pulse dust removal equipment has a poor backwashing effect on the filter bag during use and is difficult to completely clean the impurities adhering to the outside of the filter bag. The device comprises: a base frame 1; a dust removal box 2, which is fixedly connected to the base frame 1, and the dust removal box 2 is provided with an air inlet duct, an air outlet duct and a sewage discharge duct; an isolation plate 3, which is fixedly connected to the dust removal box 2, and the isolation plate 3 divides the dust removal box 2 into two upper and lower cavities, the upper cavity is connected to the air outlet duct, and the lower cavity is connected to both the air inlet duct and the sewage discharge duct; the filter bag 4 is a plurality of filter bags arranged at intervals. One end of the filter bag 4 is fixedly connected to the isolation plate 3; the fixed frame 5 is fixedly connected to the dust removal box 2; the limiting sleeves 6 are multiple and arranged at intervals, and are all fixedly connected to the fixed frame 5; the movable sleeves 7 are multiple and arranged at intervals, and are respectively slidably connected to adjacent limiting sleeves 6, and the movable sleeves 7 are fixedly connected to the other ends of the adjacent filter bags 4; the jet mechanism is arranged on the side of the dust removal box 2 close to the air outlet pipe, and is used for backflushing and cleaning the filter bags 4; the power mechanism is multiple and arranged at intervals, and is respectively arranged on adjacent movable sleeves 7, and the power mechanism is used to make adjacent limiting sleeves 6 and adjacent movable sleeves 7 slide relative to each other.

[0020] In the above scheme, the base frame 1 is welded by steel materials such as angle steel to ensure the stability of each part during the dust removal process. The air inlet pipe on the dust removal box 2 is connected to the external exhaust pipe, and the air outlet pipe on the dust removal box 2 is connected to the external pump body to discharge the exhaust gas in the dust removal box 2 (the exhaust gas after dust removal) to the outside of the equipment. The sewage pipe on the dust removal box 2 is connected to the external collection box to store the discharged dirt for subsequent same treatment. When the exhaust gas (dust-containing gas, for the sake of convenience, the following will be replaced by exhaust gas), the exhaust gas is passed into the cavity on the lower side of the dust removal box 2, and then the exhaust gas is filtered by the filter bag 4 and enters the cavity on the upper side of the dust removal box 2. During the process, the filter bag 4 removes dust in the exhaust gas, thereby achieving the purpose of exhaust gas dust removal. , the clean gas (exhaust gas after dust removal) is discharged from the equipment through the exhaust pipe. As the waste gas treatment time increases, the dust accumulated on the outside of the filter bag 4 gradually increases. When the dust accumulates to affect the normal dust removal work, the dust removal work of the waste gas is stopped, and the jet mechanism is used to backflush the filter bag 4 to remove the dust accumulated on the outside of the filter bag 4, thereby ensuring the permeability of the filter bag 4 and further ensuring the dust removal efficiency of the waste gas. In the process of backflush the filter bag 4, the power mechanism is used to make the movable sleeve 7 and the adjacent limiting sleeve 6 move relative to each other (the movable sleeve 7 drives the adjacent filter bag 4 to move), thereby changing the shape of the filter bag 4, making the filter bag 4 wrinkled, and prompting the dust adhering to the outside to detach, thereby improving the cleaning effect of the filter bag 4 and improving the subsequent dust removal efficiency of the waste gas.

[0021] like Figure 2-Figure 5 As shown, the jet mechanism includes: an air bag 801, which is installed on the upper part of the right side of the dust removal box 2, and the air bag 801 is connected to an external air pump; an air supply pipe 802, which is fixedly connected to the upper part of the dust removal box 2, and the air supply pipe 802 is connected to the air bag 801; a connecting frame 803, which is a plurality of spaced-apart arrangements, all of which are fixedly connected to the air supply pipe 802; a first movable member 804, which is a plurality of spaced-apart arrangements, is slidably connected to adjacent connecting frames 803, a cavity is provided in the first movable member 804, the cavity in the first movable member 804 is connected to the air supply pipe 802 through a hose, an elastic element 805 is fixedly connected between the first movable member 804 and the connecting frame 803, the first movable member 804 is equipped with a plurality of spaced-apart one-way valves 806, and the one-way valves 806 are connected to the cavity on the first movable member 804; a connecting plate 807, which is a plurality of spaced-apart arrangements, all of which are rotatably connected to the isolation plate 3, and the first movable member 804 is in contact with the connecting plate 807.

[0022] In the above scheme, a pressure sensor (not shown in the schematic diagram) is installed in the air outlet pipe on the dust removal box 2 to measure the pressure difference on both sides of the filter bag 4 to detect its resistance change, so as to determine whether the filter bag 4 needs to be cleaned. The elastic element 805 is a tension spring, which is used to reset the first movable member 804. The flow direction of the one-way valve 806 is from top to bottom. The hose between the first movable member 804 and the air supply pipe 802 is a bellows. In the process of dust removal of the exhaust gas, when the pressure sensor detects that the pressure at the outlet of the filter bag 4 is reduced, the air bag 801 starts to input high-pressure air into the air supply pipe 802. The high-pressure air passes through the adjacent hose (bellows) and enters the cavity in the first movable member 804. The first movable member 804 applies a downward force, that is, the first movable member 804 starts to move downward, the first movable member 804 and the connecting frame 803 slide relative to each other, and the elastic element 805 is stretched until the first movable member 804 moves downward to contact with the connecting plate 807 (partial areas on the two are intertwined with each other), and then high-pressure air flows out of the one-way valve 806 into the filter bag 4, thereby backflushing the filter bag 4 and blowing off the dust gathered on the outside of the filter bag 4. The contact between the first movable member 804 and the connecting plate 807 is used to make the filter bag 4 become "sealed" during the backflushing process, thereby preventing high-pressure air from overflowing from the outlet of the filter bag 4, thereby causing pressure loss and reducing the effect of backflushing the filter bag 4.

[0023] like Figure 4-Figure 7As shown, the power mechanism includes: a second moving member 901, which is limited and rotatably connected to an adjacent moving sleeve 7, the second moving member 901 is provided with a first protrusion, and the moving sleeve 7 is provided with a second protrusion; a first rod 902, which is fixedly connected to an adjacent connecting plate 807; a second rod 903, which is fixedly connected to an adjacent second moving member 901, the second rod 903 is splined to the first rod 902, and the first rod 902 is fixedly connected with a plurality of fan blades 904 arranged circumferentially; a spiral plate 905, which is fixedly connected between an adjacent connecting plate 807 and an adjacent second moving member 901, the spiral plate 905 is an elastic plate, the upper side of the spiral plate 905 is an inclined surface, and the thickness of the spiral plate 905 on one side close to the adjacent first rod 902 is greater than the thickness of the other side, which is used to guide the airflow so that the airflow is blown to the inner side of the filter bag 4, and the limiting sleeve 6 is provided with a first limiting groove 906, and the first limiting groove 906 is connected to the adjacent second moving member 901 on the The first protrusion is limited and matched, and the first limiting groove 906 is composed of a plurality of first grooves 9061 arranged at intervals and a plurality of second grooves 9062 arranged at intervals. The first groove 9061 and the second groove 9062 are arranged at intervals. The one-way plate 907 is located at the connection between the first groove 9061 and the second groove 9062. The limiting sleeve 6 is fixedly connected with the uniformly arranged one-way plates 907, and the one-way plates 907 are located in the first limiting groove 906. The one-way plate 907 is limited and matched with the first protrusion on the second movable member 901. The limiting sleeve 6 is provided with a second limiting groove 908, and the second limiting groove 908 is limited and matched with the second protrusion on the adjacent movable sleeve 7. The knocking assembly is a plurality of spaced-apart components, all of which are provided on the first rod 902. The knocking assembly is used to knock the adjacent filter bags 4. The connecting plate 807 is provided with a plurality of holes, and the holes are located above the adjacent fan blades 904 and the adjacent spiral plates 905, so that the airflow impacts the two.

[0024] In the above scheme, the length of the fan blade 904 is greater than the width of the spiral plate 905, and there is a space between the spiral plate 905 and the second rod 903. The upper side of the spiral plate 905 gradually tilts downward from the inside to the outside, that is, the thickness of the inner side of the spiral plate 905 is greater than the thickness of the outer side thereof, which is used to guide the high-pressure air and impact the inner side of the filter bag 4, thereby improving the backwashing effect of the filter bag 4. The first groove 9061 is an inclined groove, the second groove 9062 is a vertical groove, the one-way plate 907 is a spring plate, which is used to allow the second moving member 901 to pass (rotate) in one direction, and the second limiting groove 908 is an inclined groove. After the high-pressure air enters the filter bag 4, the high-pressure air impacts the fan blade 904, and the fan blade 904 drives the first rod 902 to rotate counterclockwise (such as Figure 6Taking the top view as an example), the first rod 902 drives the connecting plate 807 and the second rod 903 to rotate counterclockwise together, the connecting plate 807 and the isolation plate 3 rotate relative to each other, the second rod 903 drives the second movable member 901 to rotate counterclockwise together, the first protrusion on the second movable member 901 begins to slide along the first groove 9061, and then under the limiting action of the first groove 9061, the second movable member 901 moves upward while rotating counterclockwise, the spiral plate 905 is compressed, the second movable member 901 drives the movable sleeve 7 to move upward together, the second protrusion on the movable sleeve 7 begins to slide in the second limiting groove 908, and then under the limiting action of the second limiting groove 908, the movable sleeve 7 moves upward while rotating counterclockwise, and the movable sleeve 7 drives the filter bag 4 to move together, so that the filter bag 4 has "spiral" folds, thereby strengthening the degree of stripping of dust attached to the outside of the filter bag 4 and improving the cleaning effect of the filter bag 4.

[0025] When the first protrusion of the second movable member 901 contacts the adjacent one-way plate 907 (the first protrusion moves to the upper end of the first groove 9061), the first protrusion passes through the adjacent one-way plate 907 and enters the adjacent second groove 9062. Subsequently, the second movable member 901 moves downward rapidly under the elastic force of the spiral plate 905 (the first protrusion slides downward in the second groove 9062), and the movable sleeve 7 is quickly reset (rotates in the opposite direction) under the limiting action of the second limiting groove 908, so that the folds on the filter bag 4 are quickly flattened, and the dust adhering to the outer side of the filter bag 4 is detached by inertia, thereby ensuring the cleaning effect of the filter bag 4. After the first protrusion moves downward to contact the adjacent one-way plate 907, the first protrusion passes through the one-way plate 907 and enters the first groove 9061.

[0026] like Figure 5-Figure 7 As shown, the knocking assembly includes: a third rod 1001, fixedly connected to the first rod 902; a fourth rod 1002, fixedly connected to the third rod 1001, the fourth rod 1002 is tilted, the third rod 1001 and the fourth rod 1002 are both made of elastic material, and are used to knock on adjacent filter bags 4, the elastic coefficient of the third rod 1001 is greater than the elastic coefficient of the fourth rod 1002, and is used to increase the number of times the fourth rod 1002 knocks on the filter bag 4; a limiting rod 1003, fixedly connected to the second rod 903, the limiting rod 1003 is squeezed and matched with the adjacent fourth rod 1002, and the fourth rod 1002 is in contact and matched with the adjacent filter bag 4.

[0027] In the above scheme, a plurality of fourth rods 1002 are spirally distributed and used to evenly knock the filter bag 4. The fourth rod 1002 is inclined from top to bottom toward the direction close to the axis of the first rod 902. The third rod 1001 and the fourth rod 1002 are both made of spring steel. During the upward movement of the second moving member 901, the second moving member 901 drives the second rod 903 to move upward together. The second rod 903 slides relative to the first rod 902. The second rod 903 drives the limiting rod 1003 to move upward together. The limiting rod 1003 opens The fourth rod 1002 begins to be squeezed, and the fourth rod 1002 begins to deflect in the direction close to the first rod 902. The first rod 902 drives the third rod 1001 to deflect together. Then, when the second moving member 901 quickly moves downward to reset, the fourth rod 1002 quickly loses the limit on the fourth rod 1002. The fourth rod 1002 resets under its own inertia and continues to deform after being completely reset, thereby knocking the adjacent area on the inner side of the filter bag 4, so as to shake off the dust adhered to the outer side of the filter bag 4, thereby improving the cleaning effect of the filter bag 4.

[0028] Since the first protrusion on the second movable member 901 can only rotate in one direction under the limiting action of the first limiting groove 906, that is, the area where the fourth rod 1002 knocks on the inner side of the filter bag 4 also continuously changes, thereby preventing repeated knocking on the same area inside the filter bag 4 from aggravating stress concentration, thereby causing damage to a local area of ​​the filter bag 4 and affecting the normal operation of the exhaust gas dust removal work.

[0029] like Figure 1-Figure 7 As shown in FIG. 1 , an embodiment of the present invention proposes a method for using an intelligent pulse dust removal device. Based on the above-mentioned intelligent pulse dust removal device, the method includes the following steps: S1: The exhaust gas is passed into the cavity on the lower side of the dust removal box 2, and then the exhaust gas is filtered by the filter bag 4 and enters the cavity on the upper side of the dust removal box 2. During the process, the filter bag 4 removes the dust in the exhaust gas, thereby achieving the purpose of exhaust gas dust removal, and the clean gas is then discharged from the equipment through the outlet pipe; S2: When the filter bag 4 is clogged, the air bag 801 starts to input high-pressure air into the air supply pipe 802. The high-pressure air enters the first moving part 804 through the adjacent hose, and then enters the filter bag 4 through the one-way valve 806, so as to backwash the filter bag 4 and blow off the dust accumulated on the outside of the filter bag 4. S3: High-pressure air impacts the fan blades 904, causing the second movable member 901 to rotate and move, so that the movable sleeve 7 moves and rotates, thereby causing spiral folds in the filter bag 4, destroying the aggregation of dust adhering to the outside of the filter bag 4, and then the filter bag 4 is quickly reset under the action of the elastic force of the spiral plate 905.

[0030] S4: The second moving member 901 moves to drive the second rod 903 to move together, and the limiting rod 1003 squeezes the fourth rod 1002, so that the fourth rod 1002 deflects in the direction close to the first rod 902, and then uses its own elasticity to continue to deform after the rapid reset is completed, thereby knocking the adjacent area inside the filter bag 4.

[0031] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.
