Description

Technical Field

[0001] The present invention relates to the technical field of industrial waste gas treatment, and particularly relates to an energy-saving and environment-friendly industrial waste gas treatment system and a treatment method. Background Art

[0002] Industrial waste gas refers to the general term for various gases and particulate matters discharged into the atmosphere during industrial production. In the field of industrial production, during the combustion process of fuels, elements such as carbon and sulfur in the fuels react with oxygen to generate gases such as carbon dioxide and sulfur dioxide. At the same time, unburned carbon particles will also be produced. If these soot particles are directly discharged to the outside, they will pollute the environment and also affect people's physical health.

[0003] In traditional industrial waste gas treatment devices, the waste gas is first introduced into the interior of a filter. The interior of the filter is provided with filter bags to intercept a large number of fine particles, but regular maintenance and cleaning are required, resulting in poor treatment efficiency. When treating waste gas with too high soot content, obviously conventional gas filters are not sufficient, and the filter bags will soon be covered. If the dust cannot be collected in time during the cleaning process, it will make the subsequent dust filtering work difficult. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving and environment-friendly industrial waste gas treatment system to solve the above-mentioned deficiencies in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An energy-saving and environment-friendly industrial waste gas treatment system includes a waste gas treatment box. An intake pipe is provided on the outer side of the waste gas treatment box near the bottom. An exhaust port is provided at the top of the waste gas treatment box. A dust filtering component is provided inside the waste gas treatment box. The dust filtering component includes a dust filtering net. The dust filtering component is responsible for driving the dust filtering net to reciprocate up and down to accelerate the separation rate of soot in the waste gas. A dust sticking component is provided at the inner bottom of the waste gas treatment box. The dust sticking component includes a switching roller and a dust sticking film with one end fixedly wound around the switching roller. During the downward movement of the dust filtering net, the soot gradually gathers and is adsorbed by the dust sticking film. An intermittent driving component is provided at the outer end of the switching roller. The intermittent driving component is responsible for driving the switching roller to rotate when the dust filtering net reaches the bottommost position to replace the area of the dust sticking film that adsorbs soot.

[0007] Further, the dust sticking component further includes a film winding roller. Initially, multiple turns of the dust sticking film are wound around the outside of the film winding roller. A first rotating rod is fixedly connected to the inside of the switching roller. A fixed rod is rotatably connected to the inside of the film winding roller. Both ends of the fixed rod are fixedly connected to the inner wall of the waste gas treatment box. The first rotating rod movably penetrates to the outside of the waste gas treatment box.

[0008] Further, the dust filtering component includes a reduction motor disposed at the top of the waste gas treatment box. The output end of the reduction motor is fixedly connected with a reciprocating lead screw. A threaded sleeve is fixedly connected near the center of the dust filter net. The reciprocating lead screw is in threaded connection with the threaded sleeve.

[0009] Further, a cleaning component is disposed at the bottom of the reciprocating lead screw. The cleaning component includes a rotating plate. A cleaning brush is disposed at the top of the rotating plate. An activity sleeve is fixedly connected to the end of the rotating plate. The activity sleeve is rotatably connected to the outer end near the bottom of the reciprocating lead screw. A driving sleeve is disposed above the activity sleeve. A transmission component is disposed outside the driving sleeve. The transmission component is responsible for driving the cleaning brush to rotate when the dust filter net falls to the lowest position.

[0010] Further, the transmission component includes a plurality of limiting strips fixedly connected to the outer end of the reciprocating lead screw. A limiting groove adapted to the limiting strips is formed inside the driving sleeve. The driving sleeve slides on the outside of the reciprocating lead screw through the limiting strips. A linkage rod is formed at the bottom of the driving sleeve. A transmission groove is formed at the top of the activity sleeve. A telescopic member is disposed inside the transmission groove. The bottom end of the linkage rod presses the telescopic member and enters the transmission groove, causing the activity sleeve to drive the cleaning brush to rotate and clean the dust filter net.

[0011] Further, the intermittent driving component includes a first pulley. A second pulley is rotatably sleeved on the outside of the reciprocating lead screw. The second pulley is fixedly connected to the bottom of the activity sleeve. A transmission belt is disposed outside the first pulley. The first pulley, the second pulley and the transmission belt are in transmission connection. A first transmission rod is fixedly connected inside the first pulley. A first friction wheel is fixedly sleeved on the outer end of the first transmission rod. A friction belt is in transmission connection outside the first friction wheel. A second friction wheel is in transmission connection inside the friction belt. A second transmission rod is fixedly connected inside the second friction wheel. A speed reduction driving component is disposed on the second transmission rod. The speed reduction driving component is used to transmit the power of the activity sleeve to the first rotating rod to realize intermittent driving of the film winding roller to rotate.

[0012] Further, the speed reduction driving component includes a second rotating rod fixedly connected to the second transmission rod. A first reduction gear is fixedly sleeved on the outside of the second rotating rod. A second reduction gear is fixedly sleeved on the outside of the first rotating rod. The first reduction gear is in meshing connection with the second reduction gear.

[0013] Further, a blow-suction dual-purpose fan is disposed at the top of the waste gas treatment box at the exhaust port. The input end of the blow-suction dual-purpose fan is electrically connected to a controller. When the dust filter net moves downward to a low position, the blow-suction dual-purpose fan is in a blowing state.

[0014] An energy-saving and environment-friendly industrial waste gas treatment method, using the above-mentioned energy-saving and environment-friendly industrial waste gas treatment system, the steps are as follows:

[0015] Pass the waste gas into the waste gas treatment box through the air inlet pipe, and turn on the reduction motor and the blow-suction dual-purpose fan;

[0016] When the dust filter plate moves downward along with the reciprocating screw rod, the soot particles are intercepted below, causing the soot particles to gradually gather, part of which are adsorbed by the dust sticking film, and part of which adhere to the bottom surface of the dust filter plate;

[0017] When the dust filter plate approaches the lowest part, the cleaning brush starts to rotate to clean the bottom surface of the dust filter net. At this time, control the blow-suction dual-purpose fan to be in the blowing state to improve the falling efficiency of the soot particles adhering to the dust filter plate, so that the soot particles are fully adsorbed by the dust sticking film;

[0018] Meanwhile, the film winding roller starts to rotate slowly to intermittently replace the soot adsorption area of the dust sticking film.

[0019] In the above technical solution, the beneficial effects of the energy-saving and environment-friendly industrial waste gas treatment system provided by the present invention are as follows:

[0020] By driving the dust filter net to move up and down, when the dust filter net moves downward, the filtered gas is discharged from one side of the dust filter net and finally discharged through the exhaust port, while the soot at the bottom gradually gathers, attracts and adheres to each other to form larger particles, and is adsorbed by the dust sticking film, realizing the separation and collection of dust particles; Not only that, when the dust filter net moves downward, the blow-suction dual-purpose fan is set to the suction state through the controller, and the air flow movement direction is opposite to the movement direction of the dust filter net, forming a convection, which further improves the gas and soot separation rate; When the dust filter net is about to move to the bottom, the working state of the blow-suction dual-purpose fan is switched through the controller to make it start blowing, which not only blows off part of the dust adhering to the bottom of the dust filter net, but also quickly contacts the turbid soot gas deposited at the bottom with the dust sticking film, improving the adsorption effect of the dust sticking film.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are part of the embodiments of the present disclosure, rather than all of them. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0035] Example 1. Please refer to Figures 1-4 , an energy-saving and environmental-friendly industrial waste gas treatment system, including a waste gas treatment tank 1. An air inlet pipe 2 is provided on the outer side of the waste gas treatment tank 1 near the bottom. An exhaust port 3 is opened at the top of the waste gas treatment tank 1. A dust filtering component 4 is arranged inside the waste gas treatment tank 1. The dust filtering component 4 includes a dust filtering net 41. The dust filtering component 4 is responsible for driving the dust filtering net 41 to reciprocate up and down to accelerate the separation rate of the soot in the waste gas. A dust sticking component 5 is arranged at the inner bottom of the waste gas treatment tank 1. The dust sticking component 5 includes a switching roller 51 and a dust sticking film 52 with one end fixedly wound around the switching roller 51 (the dust sticking film 52 can be replaced with single-sided adhesive or electrostatic cloth). During the downward movement of the dust filtering net 41, the soot gradually gathers and is adsorbed by the dust sticking film 52. An intermittent driving component 6 is arranged at the outer end of the switching roller 51. The intermittent driving component 6 is responsible for driving the switching roller 51 to rotate when the dust filtering net 41 reaches the bottommost position to replace the area of the dust sticking film 52 that adsorbs the soot.

[0036] At the exhaust port 3 on the top of the waste gas treatment tank 1, a blow-suction dual-purpose fan 10 is provided. The input end of the blow-suction dual-purpose fan 10 is electrically connected to a controller. When the dust filtering net 41 moves downward to a low position, the blow-suction dual-purpose fan 10 is in a blowing state.

[0037] Specifically, the waste gas treatment tank 1 includes an upper shell and a lower shell. The upper shell is cylindrical. The lower shell is composed of a similar frustum of a pyramid and a cuboid. The dust filtering net 41 only moves inside the upper shell. The air inlet pipe 2 is fixedly penetrated into the inside of the lower shell, and waste gas is introduced through the air inlet pipe 2. An electromagnetic valve is arranged inside the air inlet pipe 2, which can be automatically opened and closed.

[0038] This case aims at the gas containing soot particles generated in industrial production, aiming to quickly remove fine dust particles, and then selectively introduce the filtered gas into a purified gas tank or discharge it to the outside according to actual needs.

[0039] In the further provided embodiment of the present invention, the dust filtering component 4 includes a reduction motor 42 arranged at the top of the waste gas treatment tank 1. The output end of the reduction motor 42 is fixedly connected with a reciprocating lead screw 43. A threaded sleeve 44 is fixedly connected near the center of the dust filtering net 41. The reciprocating lead screw 43 is in threaded connection with the threaded sleeve 44.

[0040] The reciprocating lead screw 43 is a bidirectional lead screw. When the reduction motor 42 is turned on, the reduction motor 42 drives the reciprocating lead screw 43 to continuously rotate. The threaded sleeve 44 moves up and down along with the reciprocating lead screw 43. When the dust filter net 41 moves downward, the filtered gas is discharged from one side of the dust filter net 41 and finally discharged through the exhaust port 3. The soot at the bottom gradually gathers, attracts and adheres to each other to form larger particles, and is adsorbed by the dust sticking film 52, realizing the separation and collection of dust particles. Moreover, when the dust filter net 41 moves downward, the blow-suction dual-purpose fan 10 is set to the suction state through the controller, and the air flow direction is opposite to the movement direction of the dust filter net 41, forming a convection, which further improves the separation rate of gas and soot.

[0041] Further, during actual operation, when the dust filter net 41 is about to move to the bottom, the working state of the blow-suction dual-purpose fan 10 is switched through the controller to start blowing. It not only blows off some of the dust adhering to the bottom of the dust filter net 41, but also quickly brings the turbid soot gas deposited at the bottom into contact with the dust sticking film 52, improving the adsorption effect of the dust sticking film 52.

[0042] In the further provided embodiment of the present invention, the dust sticking component 5 further includes a film winding roller 53. Initially, multiple turns of the dust sticking film 52 are wound around the outside of the film winding roller 53. A first rotating rod 54 is fixedly connected inside the switching roller 51. A fixed rod 55 is rotatably connected inside the film winding roller 53. Both ends of the fixed rod 55 are fixedly connected to the inner wall of the waste gas treatment box 1. The first rotating rod 54 movably penetrates to the outside of the waste gas treatment box 1.

[0043] Please refer to Figures 5-6 In the embodiment provided by the present invention, a cleaning component 7 is provided at the bottom of the reciprocating lead screw 43. The cleaning component 7 includes a rotating plate 71. A cleaning brush is provided on the top of the rotating plate 71. An end of the rotating plate 71 is fixedly connected with a movable sleeve 72. The movable sleeve 72 is rotatably connected to the outer end of the reciprocating lead screw 43 near the bottom. A driving sleeve 73 is provided above the movable sleeve 72. A transmission component 8 is provided outside the driving sleeve 73. The transmission component 8 is responsible for driving the cleaning brush to rotate when the dust filter net 41 falls to the lowest position.

[0044] A limiting ring is arranged inside the movable sleeve 72. An annular groove is provided on the reciprocating lead screw 43 corresponding to the limiting ring. The limiting ring and the annular groove are rotationally connected without friction by applying lubricating oil.

[0045] Please refer to Figure 7, Further, the transmission component 8 includes a plurality of limiting strips 81 fixedly connected to the outer end of the reciprocating lead screw 43. A limiting groove adapted to the limiting strip 81 is provided on the inner side of the driving sleeve 73. The driving sleeve 73 slides on the outside of the reciprocating lead screw 43 through the limiting strip 81. The reciprocating lead screw 43 continuously drives the driving sleeve 73 to rotate. A linkage rod 82 is fixedly connected to the bottom of the driving sleeve 73. A transmission groove 83 is provided on the top of the movable sleeve 72. A telescopic member 84 is fixedly connected to the inside of the transmission groove 83. The bottom end of the linkage rod 82 presses the telescopic member 84 and enters the transmission groove 83, causing the movable sleeve 72 to drive the cleaning brush to rotate and clean the dust filter net 41.

[0046] Specifically, through the limiting strip 81, the dust filter net 41 can only move in the vertical direction. During the downward movement of the dust filter net 41, it gradually approaches and presses the driving sleeve 73, causing the driving sleeve 73 to move downward. A guiding groove is provided on the driving sleeve 73, and a guiding groove is provided on the outside of the reciprocating lead screw 43. Therefore, the driving sleeve 73 can still rotate following the reciprocating lead screw 43 during the sliding process.

[0047] The driving sleeve 73 drives the linkage rod 82 to move downward. The linkage rod 82 has a telescopic structure and is internally provided with a first elastic member. The telescopic member 84 has a telescopic structure and is internally provided with a second elastic member (specifically, it can be a hollow tube and a movable tube sliding in the hollow tube. The outer end of the movable tube is connected to the inner wall of the hollow tube through the second elastic member). The elastic force of the first elastic member is greater than that of the second elastic member. When the linkage rod 82 is not aligned with the transmission groove 83, it starts to contract until it enters the transmission groove 83 and presses the telescopic member 84. Then the driving sleeve 73 can smoothly drive the movable sleeve 72 to rotate, causing the cleaning brush to rotate 180 degrees following the movable sleeve 72 and cleaning a general area of the dust filter net 41;

[0048] Then the threaded sleeve 44 engages with the second threaded groove (the bidirectional lead screw has two threaded grooves) and rises smoothly, causing the driving sleeve 73 to lose the upward pressure and start to rise to its original position through the elastic force of the telescopic member 84, forcing the driving sleeve 73 to separate from the movable sleeve 72. At this time, the cleaning brush stops rotating.

[0049] Specifically, during actual operation, a pressing component is also connected to the movable sleeve 72 at the top of the reciprocating lead screw 43. The pressing component includes a first collar, a second collar, and a return spring. The second collar is rotatably sleeved on the reciprocating lead screw 43. The first collar is sleeved on the reciprocating lead screw 43. Neither the first collar nor the second collar rotates following the reciprocating lead screw 43 and is connected to the second collar through the return spring. When the dust filter net 41 rises to the highest position, press the first collar to disengage the threaded sleeve 44 from one of the threaded grooves and enter the second threaded groove under the action of the return spring and move downward smoothly. When it reaches the lower part, it drives the cleaning brush to clean the other half area of the dust filter net 41, and so on.

[0050] During the cleaning process, as described above, the controller switches the working state of the blow-suction dual-purpose fan 10 to start blowing air, which not only blows off some of the dust adhering to the bottom of the dust filter net 41, but also quickly brings the turbid smoke and dust gas deposited at the bottom into contact with the dust sticking film 52, improving the adsorption effect of the dust sticking film 52, and the two cooperate with each other.

[0051] Please refer to Figure 8 , in the further solution provided by the present invention, the intermittent driving member 6 includes a first pulley 61. A second pulley 62 is rotatably sleeved outside the reciprocating lead screw 43. The second pulley 62 is fixedly connected to the bottom of the movable sleeve 72. A transmission belt 63 is arranged outside the first pulley 61. The first pulley 61, the second pulley 62 and the transmission belt 63 are in transmission connection. A first transmission rod 64 is fixedly connected inside the first pulley 61. A first friction wheel 65 is fixedly sleeved at the outer end of the first transmission rod 64. A friction belt 66 is in transmission connection outside the first friction wheel 65. A second friction wheel 67 is in transmission connection inside the friction belt 66. A second transmission rod 68 is fixedly connected inside the second friction wheel 67. A speed reduction driving member 9 is arranged on the second transmission rod 68. The speed reduction driving member 9 is used to transmit the power of the movable sleeve 72 to the first rotating rod 54 to realize intermittent driving of the film winding roller 53 to rotate.

[0052] Further, the speed reduction driving member 9 includes a second rotating rod 91 fixedly connected to the second transmission rod 68. A first reduction gear 92 is fixedly sleeved outside the second rotating rod 91. A second reduction gear 93 is fixedly sleeved outside the first rotating rod 54. The first reduction gear 92 and the second reduction gear 93 are meshed with each other.

[0053] When the movable sleeve 72 rotates, it drives the second pulley 62 to rotate. The second pulley 62 drives the first transmission rod 64 to rotate through the first pulley 61. The first transmission rod 64 drives the second transmission rod 68 to rotate through the first friction wheel 65, the friction belt 66 and the second friction wheel 67.

[0054] According to actual needs, set the tooth number ratio of the first reduction gear 92 and the second reduction gear 93. It is known that the first reduction gear 92 rotates half a circle each time. Therefore, the tooth number ratio of the first reduction gear 92 and the second reduction gear 93 can be set to 1-10:1. In this case, 4:1 is selected, that is, the first rotating rod 54 rotates 2 circles each time to wind up the dust sticking film 52 with adhered dust.

[0055] In practice, a friction wheel can be opened outside the fixed rod 55 to prevent the film winding roller 53 from unwinding a part more.

[0056] Embodiment 2. The difference between this embodiment and Embodiment 1 is that: a one-way lead screw can also be provided on the reciprocating lead screw 43, which has only one thread groove, and a ratchet and pawl structure well-known to those skilled in the art is provided between the first pulley 61 and the first transmission rod 64, so that the first transmission rod 64 can only be rotated unidirectionally by the first pulley 61. At this time, the cleaning brush can rotate 360 degrees each time.

[0057] An energy-saving and environmental-friendly industrial waste gas treatment method, using the above-mentioned energy-saving and environmental-friendly industrial waste gas treatment system, the steps are as follows.

[0058] Introduce the waste gas into the waste gas treatment box 1 through the air inlet pipe 2, and turn on the reduction motor 42 and the blow-suction dual-purpose fan 10.

[0059] When the dust filter plate moves downward along with the reciprocating lead screw 43, the soot particles are intercepted below, so that the soot particles gradually gather, part of which is adsorbed by the dust sticking film 52, and part adheres to the bottom surface of the dust filter plate.

[0060] When the dust filter plate approaches the lowest part, the cleaning brush starts to rotate to clean the bottom surface of the dust filter net 41. At this time, control the blow-suction dual-purpose fan 10 to be in the blowing state to improve the falling efficiency of the soot particles adhering to the dust filter plate, so that the soot particles are fully adsorbed by the dust sticking film 52.

[0061] At the same time, the film winding roller 53 starts to rotate slowly to intermittently replace the soot-adsorbing area of the dust sticking film 52.

[0062] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above-mentioned drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.

At this time, control the blow-suction dual-purpose fan to be in a blowing state to improve the falling efficiency of the soot particles adhering to the dust filter plate, so that the soot particles are fully adsorbed by the dust sticking film. At the same time, the film winding roller starts to slowly rotate to intermittently replace the soot adsorption area of the dust sticking film.
