A high-dust waste gas filtration and adsorption device

Abstract

The present invention discloses a high-smoke and dust waste gas filtering and adsorbing device, which relates to the technical field of high-smoke and dust waste gas filtering. It includes a circular filtering barrel, a filtering component and a cleaning component. The present invention uses a flow monitor to continuously monitor the gas flow in the exhaust pipe. When the gas flow in the exhaust pipe is lower than the interval value in the normal filtering state preset in advance due to the clogging of the filter cloth, the two-way pump is started to pump a fixed amount of water into the circular collecting barrel and then closed. The buoyancy of the water drives the buoyancy ball, the elastic rod and the elastic ball to impact the filter cloth, knocking off the particulate impurities on the filter cloth. At the same time, the exhaust gas flow entering the special-shaped cover impacts the bristles to make them swing, removing the particulate matter on the filter net. When the gas flow in the exhaust pipe returns to the normal interval value due to the filter cloth returning to normal, the two-way pump is started to pump out the water mixed with impurities in the circular collecting barrel and then closed. It can automatically clean when the flow decreases due to the clogging of the filter cloth, maintaining a good filtering state of the filter cloth without the need to stop the machine and wait.

Description

Technical Field

[0001] The present invention relates to the technical field of high-smoke and dust waste gas filtration, and more specifically, to a high-smoke and dust waste gas filtration and adsorption device. Background Art

[0002] High-smoke and dust waste gas usually refers to waste gas containing a large amount of solid particles (i.e., smoke and dust), and these particles are usually generated during industrial production processes, such as combustion processes, metal processing, cement production, chemical production, etc. High-smoke and dust waste gas needs to be filtered and adsorbed before being discharged to reduce the particulate matter content in the waste gas discharged into the atmosphere, so as to meet the requirements of environmental protection.

[0003] When the existing high-smoke and dust waste gas is filtered and adsorbed, first, the dust-containing gas enters from the lower part of the dust collector. When the gas passes through the cloth bag (filter bag), the dust and impurities are retained on the outer surface of the filter bag, while the clean air passes through the inside of the filter bag, thereby realizing the cleaning operation of the high-smoke and dust waste gas. As the filtration process progresses, the dust layer on the filter bag will gradually thicken, and the operator needs to stop the machine regularly to clean the ash to ensure the filtration effect and the normal use of the equipment.

[0004] In the actual use process of the existing technology, since the operator often needs to pause the machine and take out the filter bag for cleaning and replacement when cleaning the ash of the filtration and adsorption equipment, it is time-consuming and will affect the production efficiency and output. Moreover, the regular inspection method often fails to detect the blockage of the filter bag in time, resulting in an overloaded situation of the equipment parts and shortening the equipment life. Therefore, in view of the above technical problems, it is necessary to provide a high-smoke and dust waste gas filtration and adsorption device. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-smoke and dust waste gas filtration and adsorption device to solve the above problems.

[0006] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A high-smoke and dust waste gas filtration and adsorption device, including a circular filter barrel, a filtration component and a cleaning component, including a conical circular filter barrel fixedly connected to the lower surface of the circular filter barrel, a collection barrel fixedly connected to the lower surface of the circular filter barrel, a vortex hood fixedly connected to the inner cavity of the collection barrel through a fixed rod, an exhaust gas inlet pipe communicated with the outer surface of the circular filter barrel, including a special-shaped hood fixedly connected to the middle position of the inner cavity of the circular filter barrel, two filter elements fixedly connected to the inner cavity of the special-shaped hood, including a circular collection barrel located in the inner cavity of the special-shaped hood, the circular collection barrel is fixedly connected to the inner wall of the special-shaped hood through a mounting rod, a plurality of collection holes are opened on the upper surface of the circular collection barrel, a plurality of cleaning rods are evenly inserted into the inner cavity of the circular collection barrel, and a delivery pipe is communicated with the outer surface of the circular collection barrel.

[0008] As a further improvement of the present invention, an exhaust pipe is connected to the upper surface of the circular filter barrel, a barrel cover is installed at the lower end of the collection barrel, the waste gas inlet pipe is arranged along the tangent direction of the circular filter barrel, the purified gas is discharged from the exhaust pipe, the barrel cover ensures the airtightness of the collection barrel, and the waste gas enters the circular filter barrel from the waste gas inlet pipe.

[0009] As a further improvement of the present invention, a flow monitor is installed on the exhaust pipe, a two-way pump is installed on the delivery pipe, and the flow monitor and the two-way pump are electrically connected. The flow monitor monitors the air flow rate passing through the filtration system, and the two-way pump controls the delivery pipe to convey water source inward or draw out the water source.

[0010] As a further improvement of the present invention, the upper end of the special-shaped cover is a straight cylinder type and is connected to the exhaust pipe in a communicating manner, the middle part of the special-shaped cover is a continuous lantern shape, and the lower end of the special-shaped cover is a horn shape. The special-shaped cover is a customized cover for improving the air flow distribution.

[0011] As a further improvement of the present invention, the filter element includes a circular guide plate fixedly connected to the inner wall of the special-shaped cover, a filter cloth is fixedly connected to the inner cavity of the circular guide plate, the circular guide plate guides the wind direction, and filtration is carried out through the filter cloth to intercept the particles in the waste gas.

[0012] As a further improvement of the present invention, the circular collection barrel is located below the filter element, and the circular collection barrel is suspended and fixed inside the special-shaped cover through the cooperation of the mounting rod. The light impurities cleaned are collected by the circular collection barrel, and the outer surface shape of the circular collection barrel can guide the wind direction to move along a preset route.

[0013] As a further improvement of the present invention, clean water source is conveyed through the delivery pipe inside the circular collection barrel. The cleaning rod includes an elastic rod inserted into the circular collection barrel, and a buoyancy ball is fixedly connected to the lower end of the elastic rod. The buoyancy ball is located inside the circular collection barrel, and water source is conveyed through the delivery pipe inside the circular collection barrel. The buoyancy ball floats up by the buoyancy of water when it contacts with water.

[0014] As a further improvement of the present invention, an elastic ball is fixedly connected to the upper end of the elastic rod, and a plurality of bristles are fixedly connected to the outer surface of the elastic ball. The elastic rod and the elastic ball have certain elasticity and will shake when impacted, driving the bristles to shake, so as to carry out better cleaning.

[0015] As a further improvement of the present invention, both the elastic rod and the elastic ball are made of elastic materials, the bristles are made of flexible materials, and the buoyancy ball is made of light elastic materials. The elastic rod and the elastic ball are made of elastic materials and have certain elasticity. The bristles have certain flexibility and can shake, bend and recover, and their outer surfaces are smooth.

[0016] As a further improvement of the present invention, the vortex hood is semi-circular, and the vortex hood is suspended and fixed inside the collection bucket through a fixing rod. The vortex hood guides the wind direction to move correctly, and the semi-circular top surface can help particulate impurities slide down quickly.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] (1) In this solution, the waste gas is input into the circular filter bucket through the waste gas inlet pipe. The waste gas enters from the tangential inlet on the side of the circular filter bucket, forming a rotating air flow that spirals downward along the inner wall of the circular filter bucket. The heavier particulate matter in the waste gas moves outward under the action of centrifugal force and finally moves downward along the inner wall of the conical circular filter bucket and falls into the collection bucket for unified collection. When the heavier particulate matter falls on the vortex hood, it automatically slides down through its circular top. The waste gas that has separated from the heavier particles forms an upward flowing vortex air flow on the vortex hood. The vortex hood helps to reduce the phenomenon that the separated particulate matter is rolled up again by the air flow, and at the same time improves the air flow distribution and reduces the stagnation of the air flow at the bottom.

[0019] (2) In this solution, the trumpet-shaped opening at the lower end of the special-shaped hood effectively guides the waste gas air flow that has been separated once into it, and accelerates the gas flow through the narrow pipe, improving the separation efficiency of particulate matter. The elliptical cavity between the circular collection bucket and the special-shaped hood can increase the residence time of the waste gas and disperse it, increasing the contact area and improving the capture efficiency of particulate matter. The diameter of the filter cloth mesh holes at the lower part is larger than that of the filter cloth at the upper part, which can capture particulate matter of different sizes in the waste gas in stages and improve the filtration effect.

[0020] (3) In this solution, the flow monitor monitors the flow rate of the gas filtered in the exhaust pipe in real time. When the gas flow rate in the exhaust pipe is lower than the interval value of the gas flow rate in the normal filtration state preset in advance due to the blockage of the filter cloth, at this time, the two-way pump is started to pump a certain amount of water source into the circular collection bucket and then closed. The buoyancy of the water drives the buoyancy ball, the elastic rod and the elastic ball to impact the filter cloth, knocking down the particulate impurities on the filter cloth. And the waste gas air flow entering the special-shaped hood generates a certain wind speed and kinetic energy to impact the brush bristles to make them swing, clearing the particulate matter on the filter net. The cleared particulate matter will fall into the circular collection bucket through the collection holes and be mixed with the water. When the flow monitor monitors in real time that the gas flow rate in the exhaust pipe is within the normal interval value due to the filter cloth returning to normal, at this time, the two-way pump is started to pump out the water mixed with impurities in the circular collection bucket and then closed, automatically cleaning when the filter cloth is blocked and causing the flow rate to decrease, maintaining the good state of the filter cloth filtration without the need to stop the machine and wait.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to Figure 1-2 , a high-smoke and dust exhaust gas filtration and adsorption device, including a circular filter barrel 1, a filter assembly 2 and a cleaning assembly 3, including a conical circular filter barrel 101 fixedly connected to the lower surface of the circular filter barrel 1, a collection barrel 102 fixedly connected to the lower surface of the circular filter barrel 1, a vortex cover 105 fixedly connected to the inner cavity of the collection barrel 102 through a fixed rod 106, and an exhaust gas inlet pipe 104 communicated with the outer surface of the circular filter barrel 1.

[0033] Specifically, an exhaust pipe 107 is connected to the upper surface of the circular filter barrel 1. A barrel cover 103 is installed at the lower end of the collection barrel 102. The waste gas inlet pipe 104 is arranged along the tangential direction of the circular filter barrel 1. The vortex hood 105 is semi-circular, and the vortex hood 105 is suspended and fixed inside the collection barrel 102 through a fixing rod 106.

[0034] Further, the waste gas is input into the circular filter barrel 1 through the waste gas inlet pipe 104. At this time, the waste gas enters from the tangential inlet on the side of the circular filter barrel 1, forming a rotating air flow that spirals downward along the barrel wall of the circular filter barrel 1. The air flow enters the circular filter barrel 1 from the tangential direction, so that the centrifugal force can be maximally utilized to separate particles. It should be noted to avoid directly aiming at the central axis to prevent short-circuit phenomena.

[0035] The heavier particulate matter in the waste gas moves outward under the action of centrifugal force, and finally moves downward along the barrel wall of the conical circular filter barrel 101 and falls into the collection barrel 102 for unified collection. When the heavier particulate matter falls on the vortex hood 105, it automatically slides downward through its circular top. The waste gas that has separated from the heavier particles forms an upward flowing vortex air flow on the vortex hood 105. The vortex hood 105 helps to reduce the phenomenon that the separated particulate matter is rolled up again by the air flow, and at the same time improves the air flow distribution and reduces the stagnation of the air flow at the bottom. The vortex hood 105 is in the shape of a dome. At the same time, according to specific application requirements, the vortex hood 105 can also be designed into other shapes, such as stepped, polygonal, etc. The operator can select according to the actual situation to optimize the air flow distribution.

[0036] Embodiment 2:

[0037] Please refer to Figure 1-3 , this embodiment is based on the previous embodiment and includes a special-shaped hood 201 fixedly connected to the middle position of the inner cavity of the circular filter barrel 1. Two filter elements 202 are fixedly connected to the inner cavity of the special-shaped hood 201.

[0038] Specifically, a flow monitor 203 is installed on the exhaust pipe 107. The upper end of the special-shaped hood 201 is a straight cylinder type and is connected to the exhaust pipe 107 in a communicating manner. The middle part of the special-shaped hood 201 is in a continuous lantern shape, and the lower end of the special-shaped hood 201 is in a horn shape. The filter element 202 includes a circular guide plate 2021 fixedly connected to the inner wall of the special-shaped hood 201, and a filter cloth 2022 is fixedly connected to the inner cavity of the circular guide plate 2021.

[0039] Further, the waste gas that has been separated once enters through the horn-shaped opening at the lower end of the special-shaped hood 201. The horn-shaped opening effectively guides the air flow, reduces the resistance when the air flow enters, and at the same time avoids interference between air flows. The gas flow is accelerated through a narrow pipe, and the separation efficiency of particulate matter is improved.

[0040] The waste gas flows upward along the inner arc of the special-shaped hood 201. The inner arc of the special-shaped hood 201 is designed as an ellipse. The waste gas flows upward along the inner arc. This design can increase the path length of the air flow, extend the residence time of the particulate matter in the air flow, and contribute to more effectively separating the particulate matter.

[0041] The mesh diameter of the filter cloth 2022 at the lower inner part of the special-shaped hood 201 is larger than that of the filter cloth 2022 at the upper part, which can capture particulate matter of different sizes in the waste gas in a graded manner and improve the filtration effect. The filter cloth 2022 is made of polyester fiber material, with certain high-temperature resistance, corrosion resistance and wear resistance. It can also be replaced with polypropylene fiber or nylon fiber material according to the situation, and the operator can make a choice according to the actual situation.

[0042] When the filter cloth 2022 is blocked due to long-term filtration of particulate matter in the waste gas, the gas passing rate of the filter cloth 2022 decreases at this time. The flow rate of the filtered gas in the exhaust pipe 107 is monitored in real time by the flow monitor 203. The flow monitor 203 is a mature existing technology. The working principle and specific connection method of each component are existing technologies for those skilled in the art and will not be elaborated here too much. The flow monitor 203 presets a normal gas flow range in advance through the system. The flow rate of the filtered gas in the exhaust pipe 107 is monitored in real time by the flow monitor 203. When the gas flow rate in the exhaust pipe 107 is lower than the interval value of the preset normal filtration state gas flow rate due to the blockage of the filter cloth 2022, the system judges that the filter cloth needs to be cleaned and cleans the filter cloth in time.

[0043] Embodiment 3:

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 This embodiment is based on the previous embodiment and includes a circular collection bucket 301 located in the inner cavity of the special-shaped hood 201. The circular collection bucket 301 is fixedly connected to the inner wall of the special-shaped hood 201 through a mounting rod 302. A plurality of collection holes 305 are provided on the upper surface of the circular collection bucket 301. A plurality of cleaning rods 306 are evenly inserted in the inner cavity of the circular collection bucket 301. A delivery pipe 303 is communicated with the outer surface of the circular collection bucket 301.

[0045] Specifically, a two-way pump 304 is installed on the delivery pipe 303. The flow monitor 203 is electrically connected to the two-way pump 304. The circular collection bucket 301 is located below the filter element 202. The circular collection bucket 301 is suspended and fixed inside the special-shaped cover 201 through the cooperation of the mounting rod 302. Clean water source is transported inside the circular collection bucket 301 through the delivery pipe 303. The cleaning rod 306 includes an elastic rod 3061 inserted into the circular collection bucket 301. A buoyancy ball 3062 is fixedly connected to the lower end of the elastic rod 3061. The buoyancy ball 3062 is located inside the circular collection bucket 301. An elastic ball 3063 is fixedly connected to the upper end of the elastic rod 3061. A plurality of bristles 3064 are fixedly connected to the outer surface of the elastic ball 3063. Both the elastic rod 3061 and the elastic ball 3063 are made of elastic materials. The bristles 3064 are made of flexible materials. The buoyancy ball 3062 is made of lightweight elastic materials.

[0046] Further, when the gas flow rate in the exhaust pipe 107 is lower than the interval value of the gas flow rate in the normal filtration state preset in advance, a signal is sent to the two-way pump 304 at this time to start the two-way pump 304 to pump a certain amount of water source into the circular collection bucket 301 and then turn off the pump. The two-way pump 304 is an existing mature technology. The working principle and specific connection method of each component are prior art for those skilled in the art and will not be elaborated here. Its design allows liquid to flow in or out from two different directions. By changing the rotation direction of the pump, the flow direction of the liquid can be controlled, and the water flow direction can be flexibly changed as needed, facilitating the input and extraction of the water source.

[0047] The buoyancy of water drives the buoyancy ball 3062 and the elastic rod 3061 to move upward, hitting the filter cloth 2022 through the elastic ball 3063, knocking off the particulate impurities on the filter cloth 2022. At the same time, the bristles 3064 contact the filter cloth 2022. At this time, the exhaust gas flow entering the special-shaped cover 201 will generate a certain wind speed and kinetic energy to impact the bristles 3064, causing them to swing. The swinging bristles 3064 will brush on the filter cloth 2022, thereby removing the particulate matter on the filter screen. The bristles 3064 are made of flexible materials, made of nylon materials, with good wear resistance, suitable for long-term use, good elasticity, capable of restoring the original state, not easily deformed, and the material is also light enough to be blown and shaken by the airflow.

[0048] Through real-time monitoring by the flow monitor 203, when the gas flow rate in the exhaust pipe 107 is within the interval value of the gas flow rate in the normal filtration state preset in advance, another signal is sent to the two-way pump 304 at this time to start the two-way pump 304 to pump out the water mixed with impurities in the circular collection bucket 301 and then turn off the pump. The two-way pump 304 has instructions preset in the system and executes different instructions when receiving different signals to complete the operations of pumping and transporting water.

[0049] The buoyancy ball 3062 loses the buoyancy of water and falls again. At this time, the brush bristles 3064 leave the filter cloth 2022, avoiding blocking of some positions of the filter cloth 2022 by the brush bristles 3064, which affects the passing rate of the filter cloth 2022. The removed particulate matter will fall into the circular collection bucket 301 through the collection holes 305 and mix with water, and there will be no situation of being lifted again. The filter cloth 2022 is automatically cleaned by the buoyancy of water and the kinetic energy of the air flow, reducing the need for manual intervention and enabling timely cleaning of it.

[0050] Working principle: During the use of the device, the operator inputs the waste gas into the circular filter bucket 1 through the waste gas inlet pipe 104. At this time, the waste gas enters from the tangential inlet on the side of the circular filter bucket 1, forming a swirling air flow that spirals downward along the barrel wall of the circular filter bucket 1. The heavier particulate matter in the waste gas moves outward under the action of centrifugal force and finally moves downward along the barrel wall of the conical circular filter bucket 101 and falls into the collection bucket 102 for unified collection. When the heavier particulate matter falls on the vortex cover 105, it automatically slides downward through its circular top. The waste gas that has separated from the heavier particles forms an upward flowing swirling air flow on the vortex cover 105. The vortex cover 105 helps to reduce the phenomenon of the already separated particulate matter being rolled up again by the air flow, and at the same time improves the air flow distribution and reduces the stagnation of the air flow at the bottom.

[0051] The waste gas that has been separated once enters through the flared opening at the lower end of the special-shaped cover 201, effectively guiding the air flow, accelerating the gas flow through the narrow pipe, improving the separation efficiency of the particulate matter, and flowing upward along the outer arc of the circular collection bucket 301. The elliptical cavity can increase the residence time of the waste gas and disperse it, increasing the contact area and improving the capture efficiency of the particulate matter. The mesh diameter of the filter cloth 2022 in the lower part of the special-shaped cover 201 is larger than that of the filter cloth 2022 in the upper part, which can capture particulate matter of different sizes in the waste gas in stages and improve the filtering effect. When the filter cloth 2022 is blocked due to long-term filtering of the particulate matter in the waste gas, the gas passing rate of the filter cloth 2022 decreases at this time, and the flow rate of the filtered gas in the exhaust pipe 107 is monitored in real time by the flow monitor 203.

[0052] When the gas flow rate in the exhaust pipe 107 is lower than the interval value of the gas flow rate in the normal filtration state preset in advance, a signal is sent to the two-way pump 304 at this time to start the two-way pump 304 to pump a certain amount of water source into the circular collection bucket 301 and then turn off the pump. At this time, the buoyancy of the water drives the buoyancy ball 3062 and the elastic rod 3061 to move upward, and the elastic ball 3063 hits the filter cloth 2022, knocking off the particulate impurities on the filter cloth 2022. At the same time, the bristles 3064 contact the lower surface of the filter cloth 2022. At this time, the exhaust gas flow entering the special-shaped cover 201 will generate a certain wind speed and kinetic energy to impact the bristles 3064 and make them swing. The swinging bristles 3064 will brush on the filter cloth 2022, thereby removing the particulate matter on the filter screen. The removed particulate matter will fall into the circular collection bucket 301 through the collection hole 305 and be mixed with water, and there will be no situation of being lifted again. The bristles 3064 have a certain flexibility. When the cleaning of the filter cloth 2022 is completed, the filter cloth 2022 resumes its normal gas passing rate and is monitored in real time by the flow monitor 203. When the gas flow rate in the exhaust pipe 107 is within the interval value of the gas flow rate in the normal filtration state preset in advance, another signal is sent to the two-way pump 304 at this time to start the two-way pump 304 to pump out the water mixed with impurities in the circular collection bucket 301 and then turn off the pump. At this time, the buoyancy ball 3062 loses the buoyancy of the water and falls again. At this time, the bristles 3064 leave the filter cloth 2022 to avoid blocking the filter cloth 2022 at some positions by the bristles 3064 and affecting the passing rate of the filter cloth 2022.
