Technical Field

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

[0002] Industrial waste gas refers to the general term for various gases and particulate matter emitted into the atmosphere during the industrial production process. In the field of industrial production, during the combustion of fuel, carbon, sulfur and other elements in the fuel react with oxygen to generate gases such as carbon dioxide and sulfur dioxide, and also produce incompletely burned carbon particles. If these smoke particles are directly discharged to the outside, they will pollute the environment and affect human health.

[0003] The traditional industrial waste gas treatment device first passes the waste gas into the filter. The filter is equipped with a filter bag to intercept a large number of fine particles, but it needs regular maintenance and cleaning, resulting in poor treatment efficiency. When treating waste gas with too high smoke content, it is obvious that conventional gas filters are not enough. The filter bag will be covered quickly.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] Example 1, please refer to Figure 1-4, an energy-saving and environmentally friendly industrial waste gas treatment system, including a waste gas treatment box 1, an air inlet pipe 2 is arranged on the outer side of the waste gas treatment box 1 near the bottom, an exhaust port 3 is opened on the top of the waste gas treatment box 1, and a dust filter component 4 is arranged inside the waste gas treatment box 1, and the dust filter component 4 includes a dust filter net 41, and the dust filter component 4 is responsible for driving the dust filter net 41 to reciprocate up and down to accelerate the separation rate of smoke and dust in the waste gas; a dust sticking component 5 is arranged at the inner bottom of the waste gas treatment box 1, and the dust sticking component 5 includes a switching roller 51 and a dust sticking film 52 (the dust sticking film 52 can be replaced by a single-sided adhesive or an electrostatic cloth) with one end fixedly wound around the switching roller 51. During the downward movement of the dust filter net 41, the smoke 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, and the intermittent driving component 6 is responsible for driving the switching roller 51 to rotate when the dust filter net 41 reaches the bottom, so as to replace the smoke adsorbing area of ​​the dust sticking film 52.

[0022] A blowing and suction fan 10 is provided at the top of the exhaust gas treatment box 1 at the exhaust port 3. The input end of the blowing and suction fan 10 is electrically connected to a controller. When the dust filter 41 moves downward to a lower position, the blowing and suction fan 10 is in a blowing state.

[0023] Specifically, the exhaust gas treatment box 1 includes an upper shell and a lower shell. The upper shell is cylindrical, and the lower shell includes a tetrahedron and a rectangular parallelepiped. The dust filter 41 only moves inside the upper shell. The intake pipe 2 is fixed to the interior of the lower shell, and the exhaust gas is introduced through the intake pipe 2. An electromagnetic valve is arranged inside the intake pipe 2, which can be opened and closed automatically.

[0024] This case is aimed at the gas containing smoke particles generated by industrial production, aiming to quickly remove fine dust particles, and then selectively send the filtered gas into the purified gas box or discharge it to the outside according to actual needs.

[0025] In an embodiment further provided by the present invention, the dust filtering component 4 includes a reduction motor 42 arranged on the top of the exhaust gas treatment box 1, the output end of the reduction motor 42 is fixedly connected to a reciprocating screw 43, and a threaded sleeve 44 is fixedly connected to the dust filter net 41 near the center, and the reciprocating screw 43 and the threaded sleeve 44 are threadedly connected.

[0026] The reciprocating screw 43 is a bidirectional screw. When the reduction motor 42 is turned on, the reduction motor 42 drives the reciprocating screw 43 to rotate continuously, and the threaded sleeve 44 moves up and down with the reciprocating screw 43. When the dust filter 41 moves downward, the filtered gas is discharged from one side of the dust filter 41 and finally discharged through the exhaust port 3, while the smoke and dust at the bottom gradually gather and attract and adhere to each other to form larger particles, which are adsorbed by the dust sticky film 52, thereby realizing the separation and collection of dust particles; not only that, when the dust filter 41 moves downward, the blowing and suction fan 10 is set to the suction state through the controller, and the direction of the airflow movement is opposite to the direction of the dust filter 41, forming convection, which further improves the gas and smoke separation rate.

[0027] Furthermore, in actual operation, when the dust filter 41 is about to move to the bottom, the controller switches the working state of the blowing and sucking dual-purpose fan 10 to start blowing, which not only blows off some of the dust adhering to the bottom of the dust filter 41, but also quickly brings the turbid smoke gas deposited at the bottom into contact with the dust sticking film 52, thereby improving the adsorption effect of the dust sticking film 52.

[0028] In an embodiment further provided by the present invention, the dust-sticking component 5 also includes a film roller 53, which initially has multiple turns of dust-sticking film 52 wrapped around the outside, the switching roller 51 is fixedly connected to the inside of the first rotating rod 54, and the film roller 53 is rotatably connected to the inside of the fixed rod 55, and both ends of the fixed rod 55 are fixedly connected to the inner wall of the exhaust gas treatment box 1, and the first rotating rod 54 movably penetrates to the outside of the exhaust gas treatment box 1.

[0029] See also Figure 5-6 In the embodiment provided by the present invention, a cleaning component 7 is provided at the bottom of the reciprocating screw rod 43, and the cleaning component 7 includes a rotating plate 71, and a cleaning brush is provided on the top of the rotating plate 71. A movable sleeve 72 is fixedly connected to the end of the rotating plate 71, and the movable sleeve 72 is rotatably connected to the outer end of the reciprocating screw rod 43 near the bottom. A driving sleeve 73 is provided above the movable sleeve 72, and a transmission component 8 is provided on the outside of 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 point.

[0030] A limit ring is arranged in the movable sleeve 72, and an annular groove is provided at a position of the reciprocating screw rod 43 corresponding to the limit ring. The limit ring and the annular groove are connected to each other in a frictionless rotation by applying lubricating oil.

[0031] See also Figure 7Furthermore, the transmission component 8 includes a plurality of limit bars 81 fixedly connected to the outer end of the reciprocating screw rod 43, and a limit groove adapted to the limit bar 81 is provided on the inner side of the driving sleeve 73. The driving sleeve 73 slides on the outside of the reciprocating screw rod 43 through the limit bar 81, and the reciprocating screw rod 43 continuously rotates with the driving sleeve 73. A linkage rod 82 is fixedly connected to the bottom of the driving sleeve 73, and 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 squeezes the telescopic member 84 and enters the transmission groove 83, so that the movable sleeve 72 rotates with the cleaning brush to clean the dust filter 41.

[0032] Specifically, the limit bar 81 allows the dust filter 41 to move only in the vertical direction. During the downward movement of the dust filter 41, it gradually approaches and squeezes the drive sleeve 73, causing the drive sleeve 73 to move downward. A guide groove is provided on the drive sleeve 73, and a guide groove is provided on the outer side of the reciprocating screw 43. Therefore, the drive sleeve 73 can still rotate with the reciprocating screw 43 during the sliding process.

[0033] The driving sleeve 73 moves downward with the linkage rod 82, and the linkage rod 82 is a telescopic structure, and a first elastic member is arranged inside. The telescopic member 84 is a telescopic structure, and a second elastic member is arranged inside (specifically, it can be a hollow tube and a movable tube sliding on the hollow tube, and 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 begins to shrink until it enters the transmission groove 83 and squeezes the telescopic member 84. Then the driving sleeve 73 can smoothly rotate with the movable sleeve 72, so that the cleaning brush rotates 180 degrees with the movable sleeve 72 to clean the general area of ​​the dust filter 41; Then the threaded sleeve 44 is aligned with the second thread groove (the bidirectional screw has two thread grooves) and rises smoothly, so that the drive sleeve 73 loses the pressure from above and begins to rise to its original position through the elastic force of the telescopic member 84, forcing the drive sleeve 73 to separate from the movable sleeve 72, and the cleaning brush stops rotating at this time.

[0034] Specifically, during actual operation, a pressing assembly is required to be connected to the top movable sleeve 72 of the reciprocating screw rod 43, and the pressing assembly includes a first ring, a second ring and a reset spring. The second ring is rotatably sleeved on the reciprocating screw rod 43, and the first ring is sleeved on the reciprocating screw rod 43. The first ring and the second ring do not rotate with the reciprocating screw rod 43, and are connected to the second ring through the reset spring. When the dust filter net 41 rises to the highest point, the first ring is pressed to disengage the threaded sleeve 44 from one of the thread grooves, and enter the second thread groove under the action of the reset spring, and move downward smoothly. When it reaches the bottom, it brings the cleaning brush to clean the other half of the dust filter net 41, and so on.

[0035] During the cleaning process, as can be seen from the above, the controller switches the working state of the blowing and sucking dual-purpose fan 10, causing it to start blowing, which not only blows off some of the dust adhering to the bottom of the dust filter 41, but also quickly brings the turbid smoke gas deposited at the bottom into contact with the dust sticking film 52, thereby improving the adsorption effect of the dust sticking film 52, and the two cooperate with each other.

[0036] See also Figure 8 In the solution further provided by the present invention, the intermittent driving component 6 includes a first pulley 61, the outer rotating sleeve of the reciprocating screw rod 43 is connected with a second pulley 62, the second pulley 62 is fixedly connected to the bottom of the movable sleeve 72, a transmission belt 63 is arranged on the outside of the first pulley 61, the first pulley 61, the second pulley 62 and the transmission belt 63 are transmission-connected, the inside of the first pulley 61 is fixedly connected with a first transmission rod 64, the outer end of the first transmission rod 64 is fixedly sleeved with a first friction wheel 65, the outer transmission of the first friction wheel 65 is connected with a friction belt 66, the internal transmission of the friction belt 66 is connected with a second friction wheel 67, the inside of the second friction wheel 67 is fixedly connected with a second transmission rod 68, and a deceleration driving component 9 is arranged on the second transmission rod 68, the deceleration driving component 9 is used to transmit the power of the movable sleeve 72 to the first rotating rod 54, so as to realize intermittent driving of the film roller 53 to rotate.

[0037] Furthermore, the deceleration drive component 9 includes a second rotating rod 91 fixedly connected to the second transmission rod 68, the outer portion of the second rotating rod 91 is fixedly sleeved with a first reduction gear 92, the outer portion of the first rotating rod 54 is fixedly sleeved with a second reduction gear 93, and the first reduction gear 92 and the second reduction gear 93 are meshingly connected.

[0038] When the movable sleeve 72 rotates, it drives the second pulley 62 to rotate, and the second pulley 62 drives the first transmission rod 64 to rotate through the first pulley 61, and 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.

[0039] According to actual needs, the gear ratio of the first reduction gear 92 and the second reduction gear 93 is set. It is known that the first reduction gear 92 rotates half a circle each time. Therefore, the gear 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 is rotated 2 circles each time to reel in the dust-adhering dust-sticking film 52.

[0040] In practice, a friction wheel may be provided outside the fixed rod 55 to prevent the film winding roller 53 from unwinding an excessive portion.

[0041] Embodiment 2. The difference between this embodiment and embodiment 1 is that the reciprocating screw 43 can also be provided with a unidirectional screw having only one thread groove, and a ratchet tooth structure 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 in one direction by the first pulley 61. At this time, the cleaning brush can be rotated 360 degrees each time.

[0042] An energy-saving and environmentally friendly industrial waste gas treatment method adopts the above-mentioned energy-saving and environmentally friendly industrial waste gas treatment system, and its steps are as follows: The exhaust gas is passed from the air intake pipe 2 into the exhaust gas treatment box 1, and the reduction motor 42 and the blowing and suction dual-purpose fan 10 are turned on; When the dust filter plate follows the reciprocating screw rod 43 to move downward, the smoke and dust particles are intercepted to the bottom, so that the smoke and dust particles gradually gather together, part of which is adsorbed by the dust sticking film 52, and part of which is attached to the bottom surface of the dust filter plate; When the dust filter plate is close to the lowest part, the cleaning brush starts to rotate to clean the bottom surface of the dust filter net 41. At this time, the blowing and suction dual-purpose fan 10 is controlled to be in a blowing state to improve the falling efficiency of the smoke and dust particles adhering to the dust filter plate, so that the smoke and dust particles are fully adsorbed by the dust sticking film 52; At the same time, the film rolling roller 53 starts to rotate slowly, and the smoke adsorbing area of ​​the dust sticking film 52 is intermittently replaced.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
