Description

Technical Field

[0001] The present invention relates to an exhaust gas discharge circulation filtration device for preventing air pollution, and particularly to a filtration circulation device for preventing air pollution.

Background Art

[0002] Conventionally, exhaust gas and black smoke generated by burning waste were discharged from chimneys, so pollutants were discharged into the air, and a large amount of carbon dioxide was discharged, causing climate change. Serious air pollution has become a global problem and threatened people's health and lives. In the prior art, in order to improve the problem of exhaust gas, a water spraying device attached to the chimney atomized and sprayed a liquid to adsorb dirt and prevent environmental pollution by black smoke. Although the pollution caused by black smoke could be reduced by spraying water, the internal combustion temperature of the chimney was too high, so the water spraying system installed on the chimney was easily damaged. Therefore, there was still room for improvement in the waste incineration treatment equipment while enhancing the air cleaning performance for preventing air pollution, and solving these problems was required.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The main problem of the present invention is to solve the problem of the prior art that exhaust gas is discharged into the air and pollutes the atmosphere without being sufficiently purified, and to obtain the effect of strengthening air purification and removing abnormal odors, and to provide an exhaust gas discharge circulation filtration device for preventing air pollution.

Means for Solving the Problems

[0004] In order to solve the above problems, according to the first aspect of the present invention, there is provided an exhaust gas discharge circulation filtration device for preventing air pollution, comprising a smoke exhaust duct, a plurality of exhaust air devices, a conveying device, a filter mesh cloth, a tank cleaning device, and a cleaning device. The smoke exhaust duct has a plurality of exhaust air outlets, and the exhaust air devices are installed corresponding to the outside of the exhaust air outlets of the smoke exhaust duct and face the exhaust air outlets. The conveying device has a first conveying flow path in the horizontal axis direction and a second conveying flow path in the vertical direction. The first conveying flow path is formed around the flow paths of the respective exhaust air outlets and is connected to the second conveying flow path to form a two-stage circulating flow path. The filter mesh cloth is inserted into the circulating flow paths of the first conveying flow path and the second conveying flow path of the conveying device. The tank cleaning device is installed between the second conveying flow paths and is a liquid tank having a storage tank. The cleaning device has a plurality of roller shaft brushes and is provided at intervals in the tank cleaning device. The conveying device is electrically connected to an external power source and driven to circulate the filter mesh cloth in the circulating flow path of the conveying device. The filter mesh cloth is circulated by the first conveying flow path, passes through the flow path of the exhaust air outlet, performs a filtration process to filter air fine particles and dust, and the filter mesh cloth is circulated by the second conveying flow path to perform a cleaning process by the tank cleaning device and the cleaning device for scrubbing and cleaning. The cleaned filter mesh cloth becomes a wet mesh cloth that is wet and contains moisture. When the filter mesh cloth sufficiently adsorbs water molecules, due to the surface tension of the water molecules, it adheres to the structure of the filter mesh cloth, the filtration density of the filter mesh cloth is reduced, finer molecules are filtered, and a water film layer formed on the surface of the filter cloth adheres to the filter mesh cloth. The barrier layer formed on the surface of the water film layer effectively adheres harmful substances and absorbs abnormal odors, and sends them to the two-stage circulating filtration process and cleaning process of the first conveying flow path and the second conveying flow path, and discharges the purified gas from the exhaust air device. An exhaust gas discharge circulation filtration device for preventing air pollution is provided.

Embodiments for Carrying Out the Invention

[0007] Refer to FIGS. 1 to 4. As shown in FIGS. 1 to 4, an exhaust gas discharge circulation filtration device 100 for preventing air pollution according to an embodiment of the present invention includes a smoke exhaust duct 10 having a plurality of exhaust air outlets 11, a plurality of exhaust air devices 20, a conveying device 30, a filter mesh cloth 40, a tank cleaning device 50, and a cleaning device 60. The plurality of exhaust air devices 20 are installed corresponding to the outside of the exhaust air outlets 11 of the smoke exhaust duct 10. The conveying device 30 has a first conveying flow path 31 in the horizontal axis direction and a second conveying flow path 32 in the vertical direction. The first conveying flow path 31 and the second conveying flow path 32 are connected to each other. The first conveying flow path 31 is formed around the flow path of each exhaust air outlet 11, and the second conveying flow path 32 is formed around the liquid tank of the tank cleaning device 50 and the cleaning device 60 to form a two-stage circulating flow path. The filter mesh cloth 40 is a cloth-type filter mesh cloth, which is inserted and circulated in the first conveying flow path 31 and the second conveying flow path 32 of the conveying device 30. The tank cleaning device 50 is installed below the exhaust air outlet 11 and has a liquid tank. The cleaning device 60 has a plurality of roller brushes and is provided at intervals in the tank cleaning device 50. The conveying device 30 is electrically connected to an external power source 80 and started to circulate the filter mesh cloth 40, perform a filtering process of adsorbing and filtering floating fine particles and impurities discharged by the exhaust gas through the first conveying flow path 31, perform a cleaning process through the second conveying flow path 32, clean and purify the filter mesh cloth, perform a two-step circulating operation of filtering and cleaning by the two-stage circulating flow path, filter the exhaust gas discharged from the smoke exhaust duct, and then discharge the purified gas by the exhaust air device 20.

[0008] To understand the effects achievable by the present invention, the components of the present invention and their assembly methods will be described in detail below.

[0009] In this embodiment, the smoke exhaust duct 10 is provided with a plurality of exhaust air outlets 11 on the outer peripheral wall of the top end, a hollow duct of an appropriate length is provided inside, and the bottom is communicated with the intake port of the incinerator (not shown), so it is suitable for discharging the incinerated gas.

[0010] The plurality of exhaust devices 20 are centrifugal fans respectively installed corresponding to the outside of the exhaust port 11 of the smoke exhaust duct 10. They face the exhaust port 11, generate wind force by the rotation of the centrifugal fans 20, and discharge the gas filtered in the smoke exhaust duct 10 to the outdoor outside air.

[0011] The conveying device 30 includes a first conveying flow path 31 and a second conveying flow path 32. The first conveying flow path 31 has a horizontally oriented conveying path, presents the same horizontal axis direction as the exhaust port 11 of the smoke exhaust duct 10, and is formed around the exhaust port 11 so as to surround its flow path. The second conveying flow path 32 has a vertically oriented conveying path along the outside of the pipe wall of the smoke exhaust duct 10. The first conveying flow path 31 and the second conveying flow path 32 are connected to each other, and a two-stage circulating flow path is formed.

[0012] The first conveying flow path 31 and the second conveying flow path 32 of the above-described conveying device 30 are respectively provided at intervals on a plurality of sets of rollers 301, can circulate synchronously, and an automatic conveying stroke can be formed based on the circulating trajectory.

[0013] On the surface of each roller 301 of the above-described conveying device 30, a filter mesh cloth 40 may be wound, and a ratchet surface A may be inserted into the mesh surface of the filter mesh cloth 40 to provide an auxiliary pulling force that simultaneously pulls the filter mesh cloth 40 forward and moves it by the rotation of the roller 301 (see FIGS. 9 to 11).

[0014] The filter mesh 40 is a long strip-shaped cloth filter mesh, which circulates in the circulation channels of the first transport channel 31 and the second transport channel 32 of the transport device 30. When the filter mesh 40 passes through the first transport channel 31, it moves in the horizontal axis direction and is formed around the flow channel of the exhaust port 11 so as to surround it. The exhaust gas from the exhaust port 11 passes through the filter mesh 40 to perform the filtration process. Harmful substances such as fine particles and floating particles in the exhaust gas discharged from the exhaust port 11 of the smoke exhaust duct 10 are adsorbed, and the purified gas is sucked out by the exhaust device 20. When the filter mesh 40 passes through the second transport channel 32, a cleaning process is performed through the tank cleaning 50 and the cleaning device 60, and the filter mesh 40 is scrubbed and cleaned to remove dirt. At this time, the filter mesh 40 gets wet and becomes a wet mesh containing moisture. The filter mesh 40 sufficiently adsorbs water molecules, and due to the surface tension of the water molecules, they are attached to the structure of the filter mesh 40. The filtration density of the filter mesh 40 is reduced, finer molecules are filtered, and a water film layer formed on the surface of the filter mesh is attached to the filter mesh 40. The barrier layer formed on the surface of the water film layer effectively adheres harmful substances and absorbs strange odors. The filtered filter mesh 40 is recycled again and transported to the first transport channel 31 for filtration. The exhaust gas discharged from the exhaust port 11 of the smoke exhaust duct 10 is transported to the second transport channel 32 for a cleaning process, and the same steps are repeated. The filtration process and the cleaning process are performed by circulating in the circumferential flow channels of the first transport channel 31 and the second transport channel 32 to form a two-stage circulation filtration process.

[0015] The above-mentioned filter mesh 40 has a single-layer or multi-layer composite activated carbon filter and HEPA filter, and performs high-performance filtration on fine particles, dust, and floating particles in the exhaust gas through the filter mesh 40.

[0016] The above-mentioned filter mesh 40 of this embodiment is formed into a wet filter mesh 40. When water molecules are adsorbed by the cloth structure and adsorbed to the cloth surface mesh due to the surface tension of the water molecules, a barrier film layer is formed, which can filter ultra-fine floating particles (such as PM2.5) in the gas and prevent strange odors from being emitted.

[0017] The tank cleaning device 50 is a liquid tank 51 having an accommodation space, which accommodates an alkaline cleaning liquid. Below the bottom of the liquid tank 51, a plurality of dust buckets 52 detachably coupled are provided at intervals. At the connection points between the dust bucket 52 and the bottom of the liquid tank 51, discharge holes 53 are respectively provided to periodically clean the tank cleaning device 50 and discharge dirt from the bottom discharge hole 53 to the dust bucket 52.

[0018] The dust bucket 52 provided at the bottom of the above-described tank cleaning device 50 can be detached, cleaned, and assembled, so that it can be periodically maintained and cleaned.

[0019] The cleaning device 60 is installed in the liquid tank 51 of the tank cleaning device 50 and has a plurality of roller shafts 61. Brushes 62 provided on the outer peripheral surfaces of the roller shafts 61 automatically scrub and clean the filter mesh cloth 40 wound around the tank cleaning device 50 to perform a cleaning process.

[0020] The exhaust gas discharge circulation filtration device for preventing air pollution according to an embodiment of the present invention further includes a deviation prevention device 70. The deviation prevention device 70 includes a plurality of positioning bases 71 and two holders 72. The positioning base 71 has a C-shaped groove opening 711. The holder 72 has a clamping surface. The holder 72 is inserted into the C-shaped groove opening 711 of the positioning base 71. The positioning bases 71 are provided at intervals on both sides of the first transport flow path 31 and the second transport flow path 32 of the transport device 30. The holders 72 are installed on both sides of the filter mesh cloth 40. The holder 72 is driven by the filter mesh cloth 40 and inserted into the positioning base 71 to correct the transport positioning of the filter mesh cloth 40 and prevent deviation.

[0021] The conveying device 30 has a first conveying channel 31 in the horizontal axis direction and a second conveying channel 32 in the vertical direction connected to form a two-stage circulating channel. A filter mesh 40 is installed in the circulating channel of the conveying device 30 and circulates. On both sides of the first conveying channel 31 and the second conveying channel 32 of the conveying device 30, positioning bases 71 of the deviation prevention device 70 are provided at parallel intervals. Holders 72 are arranged on both sides of the filter mesh 40, and the holders 72 on both sides and the C-shaped notches 711 of the parallel positioning bases 71 on both sides are provided at equal intervals. When the holder 72 is inserted into the positioning base 71 as the filter mesh 40 is conveyed, the conveying channel of the filter mesh 40 is automatically corrected. Since the conveying device 30 is electrically connected to an external power source 80, when it is turned on, as shown in FIG. 5, when the conveying device starts operating, the filter mesh 40 circulates in the circulating channel of the conveying device 30, and the conveying stroke of the filter mesh 40 is maintained to run in the operating trajectory, preventing deviation. The first conveying channel 31 passes through the flow channel of the exhaust port 11, and the exhaust device 20 generates a suction force to perform a filtering process of automatically filtering and adsorbing suspended fine particles and dust in the exhaust gas. The second conveying channel 32 is provided around the tank cleaning device 50 and the cleaning device 60 to clean the filter mesh 40 to remove dirt, perform a cleaning process, and send the purified filter mesh 40 to the filtering process of the first conveying channel 31 and the cleaning process of the second conveying channel 32, forming a two-stage filtering process of alternately circulating the filtering process and the cleaning process. By discharging the purified gas from the exhaust device 20 to purify the air, the problem of the prior art that the exhaust gas is discharged into the air and pollutes the atmosphere without being sufficiently purified is solved, and the effect of strengthening the purification of the air and removing strange odors is obtained.
