Description

Technical Field

[0001] The invention relates to the technical field of filtering, and in particular to an environmentally friendly filtering device for waste gas from straw burning. Background Art

[0002] Straw burning is a common way to treat farmland waste, but with the increase in burning behavior, a large amount of harmful gases produced in the flue gas poses a serious threat to air quality and human health. Especially during the incineration process, the flue gas temperature is high and the concentration of pollutants in the flue gas is high. If there is no effective treatment method, these pollutants will be directly discharged into the atmosphere, leading to increased environmental pollution. In order to reduce the pollution of straw burning flue gas, traditional treatment methods mostly rely on filtering devices, such as bag filters or electrostatic precipitators, to remove solid particles in the flue gas. However, these filtering devices are easily corroded and damaged under high-temperature flue gas, resulting in unsatisfactory treatment effects and high maintenance costs. Therefore, cooling treatment of high-temperature flue gas has become the key to improving the effect of flue gas treatment.

[0003] Chinese patent announcement number CN113813716A discloses an environmentally friendly filter device for waste gas from straw burning, including a box body with an outlet pipe fixedly connected to the top, a waste gas inlet pipe fixedly connected to the inner wall of the box body, a motor fixedly connected to the top of the inner wall of the box body, a rotating rod fixedly connected to one end of the motor, a guide plate fixedly connected to the inner wall of the box body, and a stirring, mixing and swinging mechanism arranged inside the box body. The above document sets a stirring, mixing and swinging mechanism, and the magnet push block will rebound due to the rebound force of the small elastic strip, so that the swing plate reciprocates up and down inside the box body, so that the reciprocating rotation of the swing plate moves the water inside the box body, and the efficiency of dissolving the dust residue wrapped in the air with the water is further improved under the lateral stirring of the stirring rod, thereby ensuring that the air in the water can be reciprocated and dispersed when discharged from the outlet pipe, which can ensure the cleanliness and freshness of the air; however, the following defects still exist in the implementation process: In the implementation process of the above patent document, although the exhaust gas purification efficiency is improved by the mixing and swinging mechanism and the dissolution effect of water, there are still certain deficiencies in cooling. The high temperature in the flue gas limits the cooling efficiency of water, and may not effectively reduce the flue gas temperature in a short time, affecting the subsequent filtration and treatment effects.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] For example, see Figure 1 , Figure 2 and Figure 3 As shown, a straw burning waste gas environmental protection filtering device includes a shell 1, a cooling component 4 is fixedly connected to the upper left side of the shell 1, an air inlet 2 is opened at the bottom of the right end of the shell 1, an air outlet 6 is opened at the left rear portion of the shell 1, a transmission component 5 is fixedly connected to the left side of the shell 1, and a filtering component 3 is fixedly connected to the right part of the inner cavity of the shell 1.

[0020] In this implementation process, first, the air outlet 6 of the device needs to be connected to the flue gas at the straw burning site, and then the air inlet 2 needs to be connected to the subsequent flue gas treatment equipment, and the control panel set in the middle of the front end of the shell 1 is further adjusted, so that the control panel will start the cooling component 4 and the power source inside the transmission component 5, and then the power source inside the transmission component 5 will pump out the cooling water, and then cooperate with the cooling component 4 to cool the flue gas from the straw burning, so that the subsequent flue gas treatment desulfurization, denitrification and dust removal are more efficient, and the flue gas treated by the cooling component 4 will enter the filter component 3, so that the filter component 3 will filter the treated flue gas by cooperating with the internal components of the cooling component 4, so that when the flue gas is subsequently desulfurized and denitrified, the effects of these treatment processes can be improved, and the cooled flue gas is more likely to react with adsorbents and chemical agents, thereby reducing the concentration of harmful gases.

[0021] In addition, it should be noted that the control panel mentioned above is a conventional setting in the prior art. In this solution, only its control function is utilized, and its working principle and line connection are not elaborated in detail; Furthermore, by setting up the cooperation between the cooling component 4 and the filtering component 3, the flue gas treatment efficiency can be effectively improved. The cooling component 4 first reduces the flue gas temperature, so that the solid particles in the flue gas condense, reducing corrosion and wear on the filtering equipment, and improving the filtering efficiency. The filtering component 3 further removes particulate matter, harmful gases and pollutants in the cooled flue gas to ensure that the emissions meet environmental protection standards. The cooperation between the two not only enhances the pollutant removal effect, but also optimizes the operating safety of the equipment and extends its service life, while improving the overall energy utilization efficiency.

[0022] For further information, please refer to Figure 3 and Figure 4 As shown, the transmission component 5 includes a connecting pipe 51, a cooling component 52 is fixedly connected to the middle of the outer surface of the connecting pipe 51, a water pump 53 is fixedly connected to the upper part of the connecting pipe 51, a connecting pipe 54 is fixedly connected to the output end of the water pump 53, the other end of the connecting pipe 54 is communicated with the inner cavity of the cooling component 4, and the cooling component 52 includes a fixing plate 521, the right side of the fixing plate 521 is fixedly connected to the left side of the shell 1, the left side of the fixing plate 521 is fixedly connected to a connecting block 522, the left side of the connecting block 522 is fixedly connected to a semiconductor refrigeration plate 523, and a plurality of heat dissipation fins 524 are arranged on the left side of the semiconductor refrigeration plate 523.

[0023] In this implementation process, after the operator adjusts the parameters on the control panel in the middle of the front end of the shell 1, the control panel will control the water pump 53 to start, so that the connecting pipe 1 51 can extract water from the bottom of the left side of the shell 1, and the extracted water will cool the water inside the connecting pipe 1 51 through the semiconductor refrigeration plate 523 fixedly connected to the fixing plate 2 521 through the connecting block 522, so that the water entering the cooling component 1 4 through the connecting pipe 2 54 has a cooling effect, so that the semiconductor refrigeration plate 523 transfers heat to the air through a plurality of heat dissipation fins 524, thereby ensuring that the water entering the inner cavity of the cooling component 1 4 each time can continuously cool the smoke from the straw burning; It is further necessary to explain that the water pump 53 and the semiconductor refrigeration plate 523 mentioned above are conventional designs in the prior art, wherein the working principle of the water pump 53 is as follows: when the pump is started, the motor drives the impeller to rotate, and the rotation of the impeller generates centrifugal force, so that water is sucked in from the pump inlet and accelerated to flow to the pump outlet. In this process, the speed of the water flow increases, the pressure rises, and the water is finally delivered to the target position. Specifically, the pump draws liquid from the low-pressure area into the pump body through the high-speed rotation of the impeller, and then discharges it through the high-pressure area, thereby completing the cooling water delivery process. Here, its line connection will not be elaborated in detail; The working principle of the semiconductor refrigeration plate 523 is as follows: when current passes through a junction composed of two different materials, one side of the junction absorbs heat and becomes cold, while the other side releases heat and becomes hot. Specifically, when current passes through the semiconductor refrigeration plate 523, carriers flow between different semiconductor materials, causing one side to absorb heat and thus produce a cooling effect, while the other side releases heat. By controlling the magnitude and direction of the current, temperature difference regulation can be achieved, thereby achieving a cooling or heating effect. Here, the circuit connection thereof will not be elaborated on in detail. It is further necessary to explain that: a filter plate is provided at the water extraction position at the bottom of the connecting pipe 51, so that when the connecting pipe 51 extracts water from the bottom left side of the shell 1, the filter plate can block larger dust. When too much dust accumulates at the filter plate, an alarm will be sent to the control panel at the front of the shell 1 through the sensor, so that the operator can clean it. Furthermore, in this solution, by setting up a semiconductor refrigeration plate 523 to cooperate with a connecting pipe 1 51 fixedly connected to the input end of the water pump 53, the water temperature can be effectively controlled. When the water pump 53 extracts water from the left part of the inner cavity of the shell 1 through the connecting pipe 1 51, the pump guides the water to the semiconductor refrigeration plate 523 area, and the semiconductor refrigeration plate 523 reduces the water temperature through the Peltier effect, thereby achieving the purpose of cooling the waste gas from straw burning. In this way, the water that is continuously circulated by the pump can be kept at a relatively low temperature, effectively reducing the temperature of the waste gas, reducing the concentration of harmful substances in the flue gas, improving the processing efficiency of the subsequent filtering device, and ensuring the environmental protection effect.

[0024] For further information, see Figure 5 , Figure 6 and Figure 7 As shown, the cooling component 1 4 includes a motor 41, the output end of the motor 41 is fixedly connected to a rotating component 43 through a coupling, the outer surface of the rotating component 43 is rotatably connected to an arc block 42, the upper end of the arc block 42 is fixedly connected to the left side of the upper end of the shell 1, the bottom of the outer surface of the rotating component 43 is rotatably connected to a water storage disc 44, the left side of the outer surface of the water storage disc 44 is connected to the connecting pipe 2 54, the bottom end of the rotating component 43 is fixedly connected to a connecting rod 2 45, and the outer surface of the connecting rod 2 45 is fixedly connected to a spiral plate 46. The bottom end of the connecting rod 45 is fixedly connected to the bevel gear 47, and the middle part of the left side of the shell 1 is fixedly connected to the blocking block 48. The rotating assembly 43 includes a transmission rod 431, and the bottom end of the transmission rod 431 is fixedly connected to the connecting block 432. The bottom end of the connecting block 432 is fixedly connected to the upper end of the connecting rod 45. The outer surface of the connecting rod 45 is provided with a water inlet hole 433. The inner cavity of the water storage disc 44 is connected to the inner cavity of the spiral plate 46 through the water inlet hole 433. The outer surface of the water storage disc 44 is fixedly connected to the inner cavity of the shell 1.

[0025] In the present implementation process, after the smoke after the burning of the straw enters, the control panel installed at the front of the shell 1 will control the motor 41 to start, so that the motor 41 will drive the rotating assembly 43 to rotate through the coupling. During the rotation of the rotating assembly 43, the connecting block 432 at the bottom is fixedly connected to the connecting rod 2 45, so that the connecting rod 2 45 can drive the spiral plate 46 fixedly connected to the outer surface to rotate, so that when the connecting pipe 2 54 transports the cooling water to the inner cavity of the water storage disc 44, the cooling water can enter the inner cavity of the spiral plate 46 through the connecting block 432, and then the water inside the spiral plate 46 will flow into the inner cavity of the spiral plate 46, so that the cooling water can flow to the bottom of the shell 1; Furthermore, in the process of treating the flue gas after burning the straw, according to the principle of thermal expansion, when the air is heated, the molecular activity increases and the volume expands, thereby causing the density of the air to decrease. Since the hot air with lower density is lighter than the surrounding cooler air, it will be affected by buoyancy and rise above the air. At this time, the motor 41 drives the second connecting rod 45 to rotate through the rotating component 43, and the second connecting rod 45 will drive the spiral plate 46 fixedly connected to the outer surface when rotating to move the flue gas downward, thereby increasing the retention time of the hot gas at the position of the spiral plate 46, thereby fully cooling the hot gas, so that the temperature of the hot gas can be more fully reduced, providing more suitable temperature conditions for subsequent filtering, desulfurization and other treatment processes; It should be further explained that the motor 41 mentioned above is a conventional design in the prior art, and its working principle is: when current passes through the coil of the motor, a magnetic field is generated around it, and this magnetic field interacts with the magnetic field of the permanent magnet or electromagnet inside the motor to generate a torque. According to Ampere's law, the relationship between the direction of the current and the direction of the magnetic field determines that the coil will generate a rotational force in the magnetic field, thereby driving the motor shaft to rotate. By changing the direction of the current or the direction of the electromagnetic field, the speed and rotation direction of the motor can be controlled to achieve mechanical movement. Here, its circuit connection will not be elaborated in detail; Furthermore, when the spiral plate 46 is driven to rotate by the motor 41, the water in the inner cavity of the water storage disk 44 can enter the inner cavity of the spiral plate 46. After the water enters the inner cavity of the spiral plate 46, the bottom of the spiral plate 46 contacts the hot air. The high heat capacity of the water can quickly absorb the heat in the hot air, thereby effectively reducing the flue gas temperature, and the heat exchange effect of the water further improves the cooling efficiency. The rotating spiral plate 46 will increase the residence time of the incineration exhaust gas, so that the flue gas can be fully cooled at this position, giving full play to the cooling and heat exchange effects, thereby reducing the flue gas temperature and providing ideal temperature conditions for subsequent filtration, desulfurization and other processes.

[0026] Embodiment 2: This embodiment further filters the cooled exhaust gas based on Embodiment 1. For details, please refer to Figure 8 , Fig. 9 , Fig.10 As shown, the filter assembly 3 includes a bidirectional threaded rod 31, the left end of the bidirectional threaded rod 31 is fixedly connected to a bevel gear 32, the outer surface of the bidirectional threaded rod 31 is rotatably connected to an isolation plate 33, the middle part of the right side of the isolation plate 33 is fixedly connected to a fixed plate 37, the bottom end of the fixed plate 37 is fixedly connected to a plurality of sliding assemblies 36, the right side of the outer surface of the bidirectional threaded rod 31 is threadedly connected to a toggle plate 35, the front and rear sides of the toggle plate 35 are slidably connected to a connecting rod 34, the bottom end of the isolation plate 33 is fixedly connected to the shell 1, the right ends of the two connecting rods 34 are fixedly connected to the inner cavity of the shell 1, the sliding assembly 36 includes a matching ball 361, and the matching ball A filter bag 363 is fixedly connected to the upper end of 361, and two symmetrically arranged sliding blocks 362 are fixedly connected to the bottom of the outer surface of the filter bag 363. A spring 364 is fixedly connected to the upper end of the filter bag 363, and a matching component 365 is fixedly connected to the upper end of the spring 364. The matching component 365 includes a second shell 3651. A plurality of air-permeable grooves 3652 are provided on the outer surface of the second shell 3651, and a sliding groove 3654 matching the two sliding blocks 362 is provided on the inner surface of the second shell 3651. A fixing ring 3653 is fixedly connected to the upper end of the second shell 3651, and the bottom end of the fixing ring 3653 is fixedly connected to the upper part of the spring 364.

[0027] Specifically, in the present implementation process, the bevel gear 2 47 fixedly connected to the bottom end of the connecting rod 2 45 will mesh with the bevel gear 1 32, thereby driving the bidirectional threaded rod 31 to rotate, so that during the rotation of the bidirectional threaded rod 31, the bidirectional threaded rod 31 arranged on the outer surface can drive the toggle plate 35 to move left and right, and during the left and right movement of the toggle plate 35, the upper part of the toggle plate 35 cooperates with the matching ball 361, so that the filter bag 363 can move up and down, and during the up and down movement of the filter bag 363, it will cooperate with a number of balls arranged inside the matching component 365, so that larger particles on the inner surface of the filter bag 363 can fall into the bottom of the filter bag 363, so as to filter them, and when the toggle plate 35 is separated from the matching ball 361, the filter bag 363 will be reset due to the self-rebound downward of the spring 364 fixedly connected to the upper part, so as to facilitate the next vibration; It should be noted that when the dust inside the filter bag 363 accumulates to a certain extent, an alarm will be sent to the housing 1. At this time, the operator can open the plate on the left side of the upper part of the housing 1 to clean the dust inside it so that it can be used next time; Furthermore, by arranging a plurality of ball bearings inside the second shell 3651 to cooperate with the outer surface of the filter bag 363, the toggle plate 35 can squeeze the dust inside the filter bag 363 when cooperating with the cooperating ball 361, so that the dust inside the filter bag 363 falls to the bottom of the filter bag 363, thereby avoiding dust clogging and affecting its filtering effect.
