Description

Technical Field

[0001] The present invention relates to the field of separation, and in particular to an explosion-proof dust collector used in a dust explosion environment. Background Art

[0002] In existing industries like metallurgy, chemicals, and pharmaceuticals, production activities often generate large amounts of combustible dust. This dust can easily cause dust explosions when it encounters an ignition source. While traditional dust removal equipment can remove dust generated during production to a certain extent, when exposed to combustible, high-temperature dust, the dust-air mixture can reach its explosive limit, potentially triggering an explosion, leading to serious property damage and personal injury.

[0003] With the development of science and technology, technical personnel in related fields have also carried out a lot of optimization on explosion-proof dust collector equipment used in dust explosion environments. In order to make a more accurate comparison, the explosion-proof dust collector disclosed in the Chinese patent with publication number CN105032059A includes a dust box, an ash storage box, a dust collection chamber, a clean air chamber, a filter bag and explosion-proof components; when in use, the upper part of the inner cavity of the ash storage box is divided into an air inlet chamber and an air outlet chamber by a first explosion-proof baffle, and the blocking surface of the first explosion-proof baffle is set toward the primary air inlet. When sparks come in from the primary air inlet, they will naturally be blocked by the first explosion-proof baffle. The sparks will hit the blocking surface and lose power and automatically extinguish. In addition, the flow path of the sparks from the air inlet chamber to the air outlet chamber is curved, not in a straight line. This also increases the movement path to a certain extent, helps the sparks cool, and improves the safety of the entire device.

[0004] However, the above explosion-proof dust collector still has some shortcomings in actual use:

[0005] The above-mentioned device blocks the high-temperature dust coming out of the primary air inlet through the first explosion-proof plate. After the airflow hits the first explosion-proof plate, its own flow path is changed. The dust in the airflow will sink into the ash storage box after hitting the first explosion-proof plate. At the same time, the sparks will lose power after hitting the first explosion-proof plate, and then automatically extinguish and sink or float in the ash storage box. The first explosion-proof plate and the second explosion-proof plate of the above-mentioned device are arranged in the ash storage box. After hitting the first explosion-proof plate, the airflow will flow downward and then be discharged through the ventilation pipe on the other side of the ash storage box. During this process, the airflow will always be in contact with the dust in the ash storage chamber, and the flow of the airflow still has a certain flow rate. Therefore, when the above-mentioned device is used to treat high-temperature flammable dust, it is very easy to form a disturbance of the airflow on the dust in the ash storage chamber, forming dust accumulation and causing a dust cloud to roll up, and then a dust explosion accident is caused after the subsequent high-temperature spark-containing airflow is blown in.

[0006] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing explosion-proof dust removal equipment. Summary of the Invention

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 To the attached Figure 8 The embodiments of the present invention are described in detail.

[0035] The embodiment of the present application discloses an explosion-proof dust collector for use in a dust explosion environment. The present application is mainly used in the process of purifying flammable dust, and technically achieves the effect of purifying the airflow containing flammable dust; in particular, during the purification process, by guiding the airflow path, dust explosion accidents caused by high-temperature spark-containing dust can be effectively avoided; further, the present application also effectively reduces the flow rate of the airflow in the dust collector by diverting and guiding the airflow, thereby avoiding dust explosions caused by dust accumulation caused by high-speed airflow.

[0036] Example 1: Reference Figure 1 and Figure 2 As shown, an explosion-proof dust collector for use in dust explosion environments includes a dust box 1 with a hollow interior. The upper side of the dust box 1 is connected to an air inlet channel 10. An explosion-proof dust removal component 2 is also provided in the dust box 1 and is connected to the air inlet channel 10. During use, the high-temperature dust-laden airflow from the outside is introduced into the dust box 1 and the explosion-proof dust removal component 2 through the air inlet channel 10. The sparks in the high-temperature airflow are extinguished and cooled by the guidance of the explosion-proof dust removal component 2. The dust in the airflow is then filtered and separated by the filtering and dust removal treatment of the explosion-proof dust removal component 2. The purified airflow after filtration is guided for discharge, thereby achieving an explosion-proof dust removal treatment effect on high-temperature dust.

[0037] Reference Figure 2 and Figure 3 As shown, the explosion-proof dust removal component 2 is used to process high-temperature airflow; specifically, the explosion-proof dust removal component 2 includes:

[0038] The installation panel 20 is limited in the dust removal box 1 and divides the dust removal box 1 into a purification chamber 21 and an exhaust chamber 22.

[0039] The guide plate 23 is limited in the purification chamber 21 and divides the purification chamber 21 into a dust removal chamber 210 and an ash storage chamber 211. A plurality of through holes 24 are formed on the guide plate 23 to connect the dust removal chamber 210 and the ash storage chamber 211, and at the same time, the dust-containing airflow from the dust removal chamber 210 into the ash storage chamber 211 is preliminarily filtered.

[0040] The blocking baffle 25 is located within the dust removal chamber 210 and spaced apart from the mounting panel 20 to limit the flow path of the high-temperature airflow.

[0041] During use, after the high-temperature airflow is introduced into the dust removal chamber 210 through the air inlet channel 10, it will preferentially blow toward the blocking baffle 25 and the installation panel 20. After the sparks in the high-temperature gas hit the blocking baffle 25 or the installation panel 20, the direction and speed of the airflow will change, causing the airflow to disperse, increasing the residence time of the airflow and sparks in the dust removal chamber 210, reducing the concentration and temperature of the sparks in the high-temperature airflow, making it easier to extinguish. At the same time, the kinetic energy of the sparks transported forward with the airflow is weakened due to contact with the blocking baffle 25 and the installation panel 20, allowing heat to have more time to dissipate, further reducing the temperature of the airflow and sparks and reducing the possibility of their continued combustion.

[0042] After the dust in the high-temperature airflow hits the blocking baffle 25 or the installation panel 20, its own kinetic energy moving forward with the airflow will be partially attenuated, and then, under the influence of its own gravity, it tends to move down to the guide plate 23. Since a number of through holes 24 are formed on the guide plate 23, the dust removal chamber 210 and the ash storage chamber 211 are connected. After the airflow hits the blocking baffle 25 first, part of the airflow will enter the ash storage chamber 211 through the several through holes 24 on the guide plate 23, and the other part of the airflow will continue to penetrate into the dust removal chamber 210 until it contacts the installation panel 20, and then enter the ash storage chamber 211. Of course, it is also possible that the high-temperature airflow is directly introduced into the ash storage chamber 211 through the several through holes 24, so the air intake At least one section of the connecting section between the channel 10 and the dust removal box 1 is horizontally arranged opposite to the blocking baffle 25, so that the high-temperature airflow will first impact the blocking baffle 25 after being introduced into the dust removal box 1. Through the mutual cooperation between the blocking baffle 25, the installation panel 20, the guide plate 23 and the through hole 24, the path of the high-temperature airflow introduced into the dust removal chamber 210 is effectively guided and diverted, avoiding the accumulation of high-temperature airflow in the dust removal chamber 210 causing secondary heating of the airflow, and at the same time greatly increasing the flow path of the high-temperature airflow and sparks, so that the residence time of the airflow and sparks in the dust removal chamber 210 is increased, making it easier for sparks to extinguish and the heat to continue to dissipate, thereby avoiding dust explosion accidents caused by high-temperature sparks.

[0043] Further, refer to Figures 1 to 4As shown, in order to facilitate the discharge of the airflow, a number of connecting tubes 26 are commonly limited between the installation panel 20 and the guide plate 23, and an air guide channel 260 is formed on the connecting tube 26 to connect the dust removal chamber 210, the ash storage chamber 211 and the exhaust bin 22 to each other. Specifically, the air guide channel 260 includes a cavity formed by the hollow inside of the connecting tube 26, and an opening is provided at one end of the cavity close to the installation panel 20 to communicate with the exhaust bin 22. A number of through holes are evenly formed circumferentially on the connecting tube 26 to connect the ash storage chamber 211, the cavity and the exhaust bin 22 to each other.

[0044] Furthermore, refer to Figures 2 to 4 As shown, a filter kit 261 is mounted on the outside of the connecting tube 26 to filter the air introduced into the air guide channel 260. Filter kit 261 is preferably a conventional filter bag or filter cartridge that filters and absorbs dust. During use, the airflow containing dust particles is first filtered by the filter kit 261 connected to the outside of the connecting tube 26 as it enters the connecting tube 26 and is then introduced into the exhaust chamber 22. This separates the dust particles from the airflow, achieving a purification and dust removal effect on the air.

[0045] Reference Figures 2 to 5 As shown, the guide plate 23 includes an inclined guide plate 230 located between the dust box 1 and the mounting panel 20, with a plurality of through holes 24 formed in the guide plate 230. A guide plate 231 extends downward from the side of the guide plate 230 near the air inlet channel 10. The guide plate 231 is spaced apart from the inner wall of the dust box 1, and the connecting tube 26 is located between the guide plate 231 and the mounting panel 20. During use, after the dust-laden airflow impacts the blocking baffle 25 or the mounting panel 20, the speed and direction of the dust and airflow will change, causing some dust particles to fall onto the guide plate 230 under the influence of their own gravity. Dust particles smaller than the aperture of the through holes 24 fall directly into the dust storage chamber 211, while larger dust particles move downward along the inclined guide plate 230 and fall between the guide plate 231 and the dust box 1, thereby achieving a purification and dust removal effect on the dust-laden airflow.

[0046] Reference Figure 1 and Figure 2As shown, as an optional embodiment, a number of blocking baffles 25 can be provided according to actual needs. In this embodiment, at least two blocking baffles 25 are provided at intervals, and two adjacent blocking baffles 25 are staggered up and down and respectively connected to the dust removal box 1 and the guide plate 230. During use, due to the staggered distribution of the two adjacent blocking baffles 25 up and down, after the high-temperature airflow hits the blocking baffle 25, it will be blocked by the blocking baffle 25 it contacts, causing the forward speed of the airflow to slow down, while changing the flow path of the airflow. Through the coordination of multiple blocking baffles 25, the overall flow path of the airflow between the multiple blocking baffles 25 presents a serpentine structure. Without increasing the floor space of the equipment, the flow path of the high-temperature airflow is effectively increased, and the time it stays in the dust removal chamber 210 is prolonged, so that the high-temperature airflow can be effectively dissipated in the dust removal chamber 210 to avoid aggregation affecting heat dissipation.

[0047] Further, refer to Figure 2 and Figure 3 As shown, in order to collect the separated dust particles so that the staff can handle them in a unified manner, the guide plate 231 and the bottom of the installation panel 20 are jointly limited with a dust collecting bin 27 connected to the dust removal box 1. The ash collecting bin 27 is also connected to the dust removal chamber 210 and the ash storage chamber 211. The bottom of the ash collecting bin 27 passes through the dust removal box 1 and is connected to the outside world so that the collected dust particles can be discharged to avoid dust accumulation in the dust removal box 1.

[0048] Reference Figures 2 to 5 As shown, a horizontal panel 28 is provided between the mounting panel 20 and the dust removal box 1, and an exhaust pipe 280 is provided between the horizontal panel 28 and the dust removal box 1. The end of the exhaust pipe 280 away from the horizontal panel 28 passes through the dust removal box 1 and is connected to the outside world, so that the gas after dust removal and purification in the exhaust bin 22 can be discharged through the exhaust pipe 280.

[0049] Reference Figures 5 to 7 As shown, a plurality of recoil air pipes 281 are provided in the exhaust bin 22 corresponding to the connecting tube 26, and a pulse control valve for controlling the opening and closing of the plurality of recoil air pipes 281 is provided outside the dust removal box 1. It should be noted that the method of controlling the recoil air pipes 281 by the pulse control valve to remove dust from the filter bag is a conventional prior art method and will not be described in detail here. The method mainly involves controlling the plurality of recoil air pipes 281 by the pulse control valve to eject a high-pressure airflow into the cavity in the connecting tube 26, thereby generating a reverse airflow. The airflow is blown toward the filter bag through the plurality of through holes on the connecting tube 26, causing the filter bag or filter cartridge to expand and vibrate instantaneously, thereby effectively removing dust attached to the outer surface of the filter bag or filter cartridge. By regularly removing dust from the surface of the filter bag or filter cartridge, its filtration efficiency can be maintained, the filtration resistance can be prevented from increasing, and the long-term stable operation of the dust collector can be ensured.

[0050] Reference Figure 1 and Figure 2As shown, the dust removal box 1 is provided with an explosion vent connected to the dust removal chamber 210, and the upper limit of the explosion vent is provided with an explosion vent plate 29. It should be noted that the explosion vent plate 29 is a conventional existing metal diaphragm, which is provided with a tearing hole that can cause the metal diaphragm to break when subjected to a certain pressure shock. During normal operation, the explosion vent plate 29 seals the explosion vent, and the dust collector can perform normal dust removal work. When the pressure in the dust removal chamber 210 increases to a predetermined value that the explosion vent plate 29 can withstand, the explosion vent plate 29 can quickly respond and break, releasing the internal pressure in time. The pressure in the dust removal chamber 210 is released from the explosion vent, avoiding the pressure in the equipment from continuing to increase and causing an explosion, effectively preventing the spread of the explosion wave, and thus protecting the safety of surrounding equipment and personnel.

[0051] Example 2: Reference Figure 2 and Figure 6 As shown, on the basis of Example 1, when the flow path of the high-temperature airflow is guided by the cooperation of the guide plate 230, a plurality of blocking baffles 25 and the installation panel 20, after the airflow containing the Mars dust impacts any one of the blocking baffles 25, the Mars dust will first hit the blocking baffle 25 and be dispersed, and then cool down and extinguish to form dust falling and suspended in the dust removal chamber 210. At this time, due to the plurality of through holes 24 opened on the guide plate 230, the airflow will be guided to the ash storage chamber 211 through the through holes 24 after impacting the blocking baffle 25. At the same time, some small dust particles suspended in the dust removal chamber 210 are driven into the ash storage chamber 211. However, large dust particles larger than the aperture of the through hole 24 are difficult to pass through the through hole 24 by themselves, and fall along the inclined guide plate 230 to the ash collecting bin 27 or remain on the guide plate 230. Then, the retained large dust particles are likely to be disturbed by the air flow in the dust removal chamber 210 and suspended in the dust removal chamber 210 again. As the dust accumulates, a dust cloud is formed and ignited by the continuous input of high-temperature spark-containing airflow, which leads to the occurrence of a dust explosion.

[0052] Based on the above, when the airflow in the dust removal chamber 210 disturbs the dust and makes it re-suspended, as an optional embodiment, a guide tube 3 with a bending structure is also connected to the dust removal box 1. The upper end of the guide tube 3 is located on the upper side of the air inlet channel 10, and the lower end thereof goes downward at least over the air inlet channel 10 and the guide plate 230 and then re-connects with the dust removal chamber 210.

[0053] Further, refer to Figure 7 and Figure 8As shown, to improve the removal of dust particles remaining on the deflector plate 230, the deflector plate 230 is spaced apart from the mounting panel 20. The lower end of the guide plate 231 is also spaced apart from the dust collection bin 27. A connecting spring 30 is provided between the deflector plate 230 and the mounting panel 20, and the guide plate 231 is also connected to the dust collection bin 27 via the connecting spring 30. In the initial state, the connecting springs 30 provided on the deflector plate 230 and the guide plate 231 ensure that the deflector plate 230 and the guide plate 231 are in a floating connection. That is, the deflector plate 230 and the guide plate 231 as a whole will deflect to a certain extent as the connecting spring 30 deforms.

[0054] Since the airflow is blocked by multiple blocking baffles 25, the flow rate of the serpentine airflow flowing in the dust removal chamber 210 will continue to decay. At the same time, a number of through holes 24 are provided on the guide plate 230 to facilitate airflow. Therefore, the airflow diverted and blown toward the guide plate 230 will not continue to blow the guide plate 230 to one side.

[0055] During use, after the airflow blown in through the air inlet channel 10 hits the blocking baffle 25, the flow path of the airflow will be changed by the blocking baffle 25, resulting in a diversion state that continues to blow forward and downward toward the guide plate 230. After the airflow blows onto the guide plate 230, the guide plate 230 is forced to be offset with the flow direction of the airflow. At the same time, the guide plate 230 and the guide plate 231 are floatingly connected to the mounting panel 20 and the dust collecting bin 27 through the connecting spring 30. After the guide plate 230 is forced to deflect, the connecting spring 30 is also forced, and then the connecting spring 30 is forced to deform. After the connecting spring 30 is forced to deform, it drives the guide plate 230 and the guide plate 231 to deflect and reset, thereby driving the remaining dust on the guide plate 230 to move downward and separate from the guide plate 230.

[0056] It should be noted that since the airflow has two diversion states at the guide plate 230, namely forward and downward, when the forward airflow acts on the guide plate 230, the connecting spring 30 between the guide plate 230 and the installation panel 20 will be compressed, while the connecting spring 30 between the guide plate 231 and the ash collecting bin 27 will be stretched for a while and deflected in the direction close to the installation panel 20, causing the guide plate 230 and the guide plate 231 to deflect as a whole in the direction close to the ash collecting bin 27 for a while, and then reset under the reset push of the connected connecting spring 30.

[0057] When the downward airflow acts on the guide plate 230, the guide plate 230 and the guide plate 231 have a downward tendency as a whole, the connecting spring 30 between the guide plate 231 and the ash collecting bin 27 is compressed by the force, and the connecting spring 30 between the guide plate 230 and the installation panel 20 is stretched and deflected in the direction close to the ash collecting bin 27, and then reset under the reset push of the connected connecting spring 30. Through the mutual cooperation of the connecting spring 30 between the guide plate 230 and the installation panel 20 and the guide plate 231 and the ash collecting bin 27, when the airflow acts on the guide plate 230, the guide plate 230 and the guide plate 231 will be in a shaking state as a whole, thereby prompting the dust remaining on the guide plate 230 to separate from it.

[0058] During operation: Step 1: The high-temperature dust-laden airflow enters the dust removal chamber 210 in the dust removal box 1 through the air inlet channel 10, and the airflow is guided and diverted by the guide plate 23 and the blocking baffle 25, thereby reducing the flow speed of the airflow and guiding the sparks in the airflow to extinguish.

[0059] Step 2: After the airflow is guided and diverted, it is introduced into the ash storage chamber 211 through the through hole 24 on the guide plate 23, and then the dust-laden airflow is filtered and dust-removed through a number of connecting tubes 26 and filter kits 261 in the ash storage chamber 211, and the purified airflow is introduced into the exhaust bin 22 and then discharged.

[0060] Step 3: Due to the reduction in flow velocity of the diverted airflow, the dust and spark-containing dust in it impact the blocking baffle 25 and then fall to the guide plate 23. The dust is guided and separated by the guide plate 23 and driven to fall into the dust collection bin 27 for subsequent processing by the staff.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0062] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
