Description

Technical Field

[0001] The invention relates to the technical field of flue gas condensation, and in particular to a flue gas condensation device with a waste heat recovery function. Background Art

[0002] Boilers consume huge amounts of energy in industrial production. In traditional boilers, after the fuel is burned in the boiler, the exhaust gas temperature is relatively high, and the water vapor in the flue gas is still in a gaseous state, which will take away a large amount of heat. This not only causes a large amount of energy waste but also aggravates the thermal pollution of the environment. Therefore, it is necessary to design a flue gas condensation device. At the same time, when the existing condensing equipment deals with the dust entering the body, it often uses filters, filter elements and other equipment to be set at the air inlet. When working for a long time, the filters and filter elements will be blocked, thereby affecting their working efficiency. In addition, the gas after entering the condenser will be adsorbed on the heat-conducting fins, which will also affect the thermal conductivity of the heat-conducting fins, and thus affect the heat exchange effect of the condenser.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: Figure 1-Figure 10 As shown, the present invention provides a technical solution of a flue gas condensing device with a waste heat recovery function, including a condensing device body 1 and a controller 11, the condensing device body 1 includes a condensing box 12, the condensing box 12 is respectively provided with an air intake pipe 121 and an exhaust pipe 122, a negative ion generator 13 is installed on the air intake pipe 121, a return air component 2 and an exhaust air component 3 are installed in the exhaust pipe 122, a support block 14 is installed inside the condensing box 12, a plurality of heat exchange components 4 are installed on the support block 14, a plurality of ash collecting grooves are provided on the support block 14, a collecting component 5 is installed inside the ash collecting groove, the collecting component 5 can collect and uniformly discharge the dust in the ash collecting groove, a positive plate 15 is installed at the bottom of the ash collecting groove, the positive plate 15 cooperates with the negative ion generator 13, and the positive plate 15 and the negative ion generator 13 are respectively connected to the controller 11; Therefore, when the device is in use, it is first necessary to connect the air inlet pipe 121 to the air outlet pipe of the boiler, so as to facilitate the condensation of the flue gas discharged from the boiler and recycle part of its heat. When in use, the flue gas entering the device will first pass through the negative ion generator 13, which will give negative ions to the neutral particles in the flue gas, so that most of the particles have negative charges. Then the smoke enters the condensation box 12, and the heat of the smoke can be converted through the heat exchange component 4. Because the heat exchange component 4 of the device is also connected to negative electricity, it can prevent part of the smoke from being adsorbed on the heat exchange component 4, and the smoke with negative electricity The dust will be attracted by the ash collecting trough and adsorbed onto the positive plate 15 on the ash collecting trough. Then, the dust on the positive plate 15 can be collected by the movement of the collecting component 5. Then, the collecting component 5 mainly uses its own inertia to move to the ash discharge port 16. At the same time, the speed will not be too fast, but will move slowly, so as to prevent the smoke and dust from being raised again. When the device is exhausting, the gas to be discharged will first pass through the return air component 2, and part of the gas can be returned and blown to the heat exchange component 4 through the return air component 2, so that the heat exchange component 4 can better absorb and utilize the heat.

[0019] like Figure 3 and Figure 6 As shown, in this embodiment, specifically, an ash discharge port 16 is provided at the bottom of the condensing box 12, and the ash discharge port 16 is located at the bottom of the exhaust pipe 122. The ash collecting trough is obliquely installed between the support blocks 14, and the ash collecting trough is located at one end of the air inlet pipe 121 higher than one end of the exhaust pipe 122. Slide grooves 17 are respectively provided on the support blocks 14 on both sides of the ash collecting trough, and a copper tube is installed inside the slide groove 17, and a magnet sheet 171 is provided inside the copper tube, and the magnet sheet 171 cooperates with the collecting component 5. A driving groove is provided at the bottom of the slide groove 17, and a driving component 6 is installed inside the driving groove, and the driving component 6 cooperates with the collecting component 5. Because one end of the ash discharge trough of the device is higher than the other end, the collecting component 5 located inside the ash discharge trough can move from the higher end to the lower end of the ash discharge trough. This process only needs to coordinate with the height of the ash discharge trough and its own inertia. At the same time, when the collecting component 5 moves, because of the cooperation with the magnet piece 171, its own moving speed will be reduced. Because the magnet piece 171 passes through the copper tube due to electromagnetic induction, the magnet piece 171 will move slowly in the copper tube, and the magnet piece 171 will attract the collecting component 5, thereby increasing the resistance of the collecting component 5, thereby reducing the moving speed of the collecting component 5. When the collecting component 5 moves to the ash discharge port 16, the driving component 6 can bring the collecting component 5 to the highest point of the ash discharge trough, and then perform a second dust collection. At this time, the positive plate 15 and the driving component 6 are both in the power-off state.

[0020] like Figure 6 and Figure 8As shown, in this embodiment, specifically, transmission components 7 are installed on both sides of the collection component 5, and the transmission component 7 includes a combined magnet 71, one side of the combined magnet 71 attracts each other with the magnet sheet 171, and the combined magnet 71 and the magnet sheet 171 attract one side and are equidistantly provided with multiple groups of positive magnets and negative magnets, and the other side of the combined magnet 71 is installed with a gear 72, one end of the gear 72 is connected to the combined magnet 71 through a bearing, and the other end of the gear 72 is connected to the collection barrel; The transmission component 7 of the device mainly cooperates with the magnet sheet 171 to reduce the self-moving speed of the collection component 5. When in use, the combined magnet 71 and the magnet sheet 171 attract each other, and the gear 72 can rotate under the rotation of the collection component 5, preventing the collection component 5 from moving in a translational state.

[0021] like Figure 6-Figure 8 As shown, in this embodiment, specifically, limit plates 51 are installed on both sides of the collecting component 5, and transmission components 7 are installed on both sides of the outer surfaces of the limit plates 51, and a plurality of arc-shaped scrapers 52 and a limit rod 53 are installed between the two groups of the limit plates 51. Bristles are provided on both sides of the arc-shaped scrapers 52, and one end of the arc-shaped scrapers 52 is connected to the limit rod 53 through a bearing. A limit bin 54 is installed on the opposite side of the two groups of the limit plates 51, and a limit groove is provided inside the limit bin 54. A pressure sensing plate 541 is installed at the end of the limit groove, and two groups of counterweights 542 are installed inside the limit groove. The pressure sensing plate 541 is connected to the controller 11, and two groups of return springs 55 are installed between the limit bin 54 and the arc-shaped scraper 52, and the return spring 55 is connected to the controller 11; The collecting component 5 of the device can collect the smoke on the ash collecting trough and the positive plate 15, which is convenient for the subsequent emission and cleaning of the smoke. When in use, the collecting component 5 rolls from the high end of the ash collecting trough to the low end along the driving component 6 in the slide 17 under its own gravity and the cooperation of the gear 72. When the collecting component 5 rolls, the arc scraper 52 opens and closes. The arc scraper 52 does not close when it contacts the positive plate 15 vertically, but closes a certain angle when it contacts the positive plate 15, and is completely closed during the subsequent rotation. Because when the collecting component 5 rotates, the limit bin 54 inside it will also rotate synchronously, and the counterweight block 542 inside the limit bin 54 will fall into different limit slots as the outside world rotates, thereby applying pressure to the pressure sensing plate 541 in the limit slot. When the pressure sensor detects the corresponding gravity, the controller 11 will supply power to the reset spring 55. When the reset spring 55 is energized, the iron molecules inside the spring will move, causing each turn of the spring to attract each other, thereby achieving the effect of contracting the spring, thereby pulling the arc scraper 52 to contract.

[0022] like Figure 7As shown, in this embodiment, specifically, the pressure sensing plate 541 detects that the weights of one set of counterweights 542 and two sets of counterweights 542 are different, and the power provided to the spring by the controller 11 is also different, and the power provided by one set of counterweights 542 is less than the power provided by the two sets of counterweights 542; Because the gravity of the counterweight 542 of the device is fixed, the only thing that changes is the angle. The impact is whether the counterweight 542 is in full contact with the pressure sensing plate 541. When the pressure sensing plate 541 detects the gravity of 0.5 groups of counterweights 542, the controller 11 will pass a certain amount of electricity to the return spring 55 to shrink part of the arc scraper 52. When the pressure sensing plate 541 detects the weight of 1.5 groups of counterweights 542, the control will increase the power connected to the return spring 55, thereby better shrinking the return spring 55.

[0023] like Figure 2 , Figure 9-10 As shown, in this embodiment, specifically, the heat exchange component 4 includes a heat conductive sheet 41, the heat conductive sheet 41 is connected to a negative electrode, and the two ends of the heat conductive sheet 41 are respectively connected to the support block 14 and the condensation box 12 through bearings, and the heat conductive sheets 41 are mutually connected with copper tubes, and a limiting ring 42 is installed above the heat conductive sheet 41, and two groups of limiting blocks 43 are installed on the base surface of the heat conductive sheet 41, and the limiting blocks 43 are installed inside the limiting ring 42, and a water inlet is opened above the heat conductive sheet 41, and a water outlet is opened below the heat conductive sheet 41, and the water inlet and the water outlet are respectively connected to the copper tubes; The water inlet of one group is connected to the external cooling medium, and the water outlet is connected to the water outlet of another group, and the water inlet and water outlet of the subsequent heat conducting sheet 41 are respectively connected to the water outlet and water inlet of the next group; When in use, the heat exchange component 4 of the device can utilize the waste heat of the boiler. During specific use, the cooling liquid is supplied to the copper tube from the water inlet of a group of heat conductive plates 41 through an external water tank. Because the heat conductive plates 41 of the device are connected to negative electricity, the smoke and dust that initially enters the device will not come into contact with the heat conductive plates 41 until water droplets condense on the heat conductive plates 41 and the copper tubes after heat exchange, which will cause part of the smoke and dust to be adsorbed on the water droplets. However, the heat conductive plates 41 of the device will swing to a certain extent under the blowing of wind, and the water droplets condensed on the heat conductive plates 41 and the copper tubes will fall off under the swinging and be collected by the ash collecting trough.

[0024] like Figure 3 As shown, in this embodiment, specifically, a current detector 18 is installed inside the support block 14, the current detector 18 is connected to the positive plate 15, and the negative ion generator 13 cooperates with the current detector 18; When the neutral medium carrying negative ions comes into contact with the positive plate 15, a small amount of current will be generated between the two. The current generated on the positive plate 15 can be detected by the current detector 18. When the generated current is small, the power of the negative ion generator 13 will be increased. When the power of the negative ion generator 13 is increased and the generated electricity is still small, the power of the negative ion generator 13 will be reduced after a certain period of time.

[0025] like Figure 2-Figure 3 and Figure 5 As shown, in this embodiment, specifically, the return air assembly 2 includes a return air motor 21, an outer air guide cover 22 and an inner air guide cover 23. The outer air guide assembly is connected to the exhaust pipe 122 through a bearing. The inner air guide cover 23 is installed inside the outer air guide cover 22. The inner air guide cover 23 is connected to the outer air guide cover 22 through a bearing. An air inlet is opened in the middle of the inner air guide cover 23. The output end of the return air motor 21 is connected to the upper side of the outer air guide cover 22, and the return air motor 21 is connected to the controller 11. When in use, the return air component 2 of the device can guide part of the gas to be discharged and blow it back to the heat exchange component 4. During specific use, when the gas is blown to the return air component 2, most of the gas will enter the inner guide cover 23, and a small part will enter the return air channel between the outer guide cover 22 and the inner guide cover 23. However, because the wind blowing in is continuous, the wind entering the inner guide cover 23 will blow from the return air channel to the heat exchange component 4. At the same time, the direction of the return air can be changed by the return air motor 21, thereby blowing the heat exchange component 4 to swing.

[0026] like Figure 3 As shown, in this embodiment, specifically, the exhaust assembly 3 includes an exhaust motor 31 and a mounting frame 32, the exhaust motor 31 is installed in the middle of the mounting frame 32 through multiple sets of connecting rods, and an exhaust fan blade 33 is installed at the output end of the exhaust motor 31, and the exhaust fan blade 33; The exhaust assembly 3 can guide the exhausted gas to prevent the gas from circling in the condensation box 12. When in use, the exhaust motor 31 can drive the exhaust fan blades 33 to rotate, generate outward wind force, and then guide the internal gas.

[0027] like Figure 4 As shown, in this embodiment, specifically, the driving assembly 6 includes a dual-external-shaft motor 61 and two sets of conveyor belts 62, the output ends of the dual-external-shaft motor 61 are respectively connected to the two sets of conveyor belts 62, the conveyor belts 62 are located inside the driving slot, and multiple sets of saw teeth 63 are installed outside the conveyor belts 62, and the saw teeth 63 cooperate with the gear 72; The driving component 6 can drive the gear 72 to rotate, and then change direction to drive the collecting component 5 to rotate. During specific use, the dual external shaft motor 61 can drive two sets of conveyor belts 62 to rotate. When the conveyor belt 62 rotates, the outer saw teeth 63 will move, thereby driving the gear 72 to rotate.

[0028] Working principle: When the device is in use, the air inlet pipe 121 needs to be connected to the air outlet pipe of the boiler first, so as to facilitate the condensation of the flue gas discharged from the boiler and recycle part of its heat. When in use, the flue gas entering the device will first pass through the negative ion generator 13, which will give negative ions to the neutral particles in the flue gas, so that most of the particles have negative charges. Then the smoke enters the condensation box 12, and the heat of the smoke can be converted through the heat exchange component 4. Because the heat exchange component 4 of the device is also connected to negative charges, it can prevent part of the smoke from being adsorbed on the heat exchange component 4, and at the same time has negative charges. The smoke and dust will be attracted by the ash collecting trough and adsorbed onto the positive plate 15 on the ash collecting trough. Then, the dust on the positive plate 15 can be collected under the movement of the collecting component 5. Then, the collecting component 5 mainly uses its own inertia to move to the ash discharge port 16 during the movement. At the same time, the speed will not be too fast, but will move slowly, so as to prevent the smoke and dust from being raised again. When the device is exhausting, the gas to be discharged will first pass through the return air component 2, and part of the gas can be returned and blown to the heat exchange component 4 through the return air component 2, so that the heat exchange component 4 can better absorb and utilize the heat.

[0029] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
