DETAILED DESCRIPTION

[0021] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0022] See also Figure 1-11 The present invention provides a technical solution: a heating furnace waste gas treatment device, comprising a heating furnace body 1, heat storage chambers 2 are arranged on both sides of the heating furnace body 1, a treatment box 4 is fixedly connected to the top of the heating furnace body 1 for treating the waste gas, a connecting pipe 10 is fixedly connected to the surface of the heating furnace body 1, a suction fan is arranged on the heat storage chamber 2 on one side, and the air outlet of the suction fan is connected to the connecting pipe 10, so that the waste gas entering the heat storage chamber 2 on one side can be extracted and injected into the treatment box 4, so as to facilitate the subsequent treatment of the waste gas.

[0023] The surface of the treatment box 4 is fixedly connected with a discharge pipe 3 connected to the inside of the treatment box 4 to discharge the treated exhaust gas. The upper and lower sides of the inner wall of the treatment box 4 are fixedly connected with partitions 6. The partition 6 divides the space inside the treatment box 4 into a pre-treatment chamber and a treatment chamber. The inner wall of the pre-treatment chamber is fixedly connected with an injection pipe 9 protruding from the surface of the treatment box 4. The end of the injection pipe 9 located inside the pre-treatment chamber is fixedly connected with a flow pipe 20 arranged in a bent shape. The end of the injection pipe 9 located outside the treatment box 4 can be connected to a seawater delivery pipeline to deliver seawater to the treatment box 4 to treat the exhaust gas. The provision of the flow pipe 20 prolongs the conveying time of seawater in the pretreatment chamber, thereby increasing the coexistence time of the exhaust gas and seawater, and enables the device to use the waste heat of the exhaust gas to heat the seawater, thereby avoiding the subsequent high-temperature exhaust gas directly contacting the relatively low-temperature seawater, so that the temperature of the flue gas is lower after treatment, thereby increasing the exhaust temperature of the flue gas, avoiding the formation of condensed water under external hot air conditions, reducing corrosion to the equipment, and at the same time allowing the flue gas to obtain a higher lifting height, so that it can diffuse into the atmosphere more effectively, reducing the impact on the ground environment, ensuring the smooth discharge of the flue gas, and improving the use effect of the device, which is worthy of promotion.

[0024] One end of the connecting pipe 10 located inside the treatment box 4 is rotatably connected to the rotating pipe 17, the inner wall of the rotating pipe 17 is fixedly connected to a fixing frame 43, and the surface of the fixing frame 43 is fixedly connected to a second turbine 42. Through the setting of the second turbine 42, the impact force of the exhaust gas entering the rotating pipe 17 can be utilized to impact the second turbine 42, thereby driving the rotating pipe 17 to rotate, providing power for the operation of the device.

[0025] The end of the flow pipe 20 away from the injection pipe 9 is fixedly connected to the spray pipe 5, which passes through the surface of the partition 6 and is fixedly connected to the inside of the partition 6. A nozzle is provided on the surface of the spray pipe 5 to drain the seawater and spray the exhaust gas.

[0026] An installation groove 8 is provided inside the partition 6, and a filter screen 7 is slidably connected to the inner wall of the installation groove 8 to filter the exhaust gas, intercept particulate matter in the exhaust gas, and pre-treat the exhaust gas, thereby avoiding the mixing of particulate matter and seawater, reducing the quality of seawater, and affecting the subsequent recycling of seawater, thereby improving the use effect of the device and worthy of promotion.

[0027] Both sides of the inner wall of the treatment chamber are fixedly connected with inclined baffles 41. The setting of the two baffles 41 can block the flow of exhaust gas so that the exhaust gas can only be discharged through the gap between the two baffles 41. Since the two baffles 41 are inclined surfaces, the sprayed seawater can be guided to be discharged to the gap between the two baffles 41. Since the seawater and the exhaust gas are discharged from between the two baffles 41, the exhaust gas can fully react with the seawater, thereby improving the exhaust gas treatment effect.

[0028] The inner wall of the treatment chamber is fixedly connected with a corridor-shaped guide plate 44, and the guide plate 44 is located between the two baffles 41. Through the setting of the guide plate 44, the flow of seawater and exhaust gas can be guided, and the flow time of the exhaust gas and seawater between the two baffles 41 can be extended, providing sufficient reaction time for the exhaust gas and seawater, thereby ensuring the treatment effect of the device on the exhaust gas.

[0029] The surface of the rotating tube 17 is slidably connected with moving rings 15 which are arranged at equal intervals. The moving rings 15 and the rotating tube 17 can be connected by spline to ensure that when the rotating tube 17 rotates, it can drive the moving rings 15 to rotate without affecting the mutual sliding between the rotating tube 17 and the moving rings 15. The surface of the moving ring 15 is fixedly connected with knocking plates 14 which are arranged at equal intervals. The surface of the knocking plates 14 is in contact with the surface of the flow tube 20 to knock and vibrate the flow tube 20 so that the particulate matter attached to the surface can be shaken off, thereby avoiding the situation where there are too many impurities attached to the surface of the flow tube 20, which affects the heating of the flow tube 20 by the exhaust gas and reduces the heat exchange efficiency, thereby ensuring the efficiency of the device in utilizing the waste heat of the exhaust gas.

[0030] The surface of the rotating tube 17 is fixedly connected with equidistantly arranged fixed rings 18, which are located on one side of the moving ring 15. The surface of the rotating tube 17 is movably sleeved with equidistantly arranged reset springs 19, and the two ends of the reset spring 19 are respectively fixedly connected to the surfaces of the fixed ring 18 and the moving ring 15 to reset the moving ring 15. The inner wall of the pretreatment chamber is fixedly connected with a protrusion 11 with a trapezoidal cross-section, which blocks the rotation path of the knocking plate 14.

[0031] A plurality of cleaning components 16 are disposed on the surface of the rotating tube 17 . The cleaning components 16 and the knocking plate 14 are respectively located on both sides of the flow tube 20 , and clean both sides of the flow tube 20 .

[0032] The cleaning assembly 16 includes a second shunt pipe 39 and a first shunt pipe 33. The second shunt pipe 39 and the first shunt pipe 33 are both fixedly connected to the surface of the rotating tube 17 and are communicated with the interior of the rotating tube 17. The second shunt pipe 39 and the first shunt pipe 33 are arranged on the rotating tube 17 in a circularly equidistant manner. The surface of the first shunt pipe 33 is fixedly connected to the first fixed shell 32. The inner wall of the first fixed shell 32 is slidably connected to the movable shell 35. The side of the movable shell 35 away from the first fixed shell 32 is an inclined surface. The surface of the first shunt pipe 33 is movably sleeved with a second spring 34. The two ends of the second spring 34 are respectively fixedly connected to the surfaces of the first fixed shell 32 and the movable shell 35. Next, a moving tube 36 is fixedly connected to the inner wall of the moving shell 35, and the surface of the moving tube 36 is slidably connected to the inner wall of the first branch pipe 33. A through hole is provided on the surface of the moving tube 36, so that the exhaust gas can be discharged through the through hole on the moving tube 36, and the surface of the flow tube 20 is blown to reduce the particle attachment on the surface of the flow tube 20. A through groove 38 is provided at the bottom of the moving shell 35 to provide a discharge channel for the exhaust gas discharged from the through hole. A steel brush 37 is fixedly connected to the surface of the moving shell 35 to brush the surface of the flow tube 20, thereby avoiding the adhesion of particles to the side of the flow tube 20 close to the through hole, thereby affecting the exhaust gas heating the seawater inside the flow tube 20.

[0033] The surface of the second diverter tube 39 is fixedly connected to the second fixed shell 40, the surface of the second fixed shell 40 is also provided with a through groove 38, the surface of the second fixed shell 40 is also fixedly connected to the steel brush 37, and the surface of the second diverter tube 39 is also provided with a through hole, so that the second diverter tube 39 cooperates with the movable tube 36 to comprehensively clean one side of the flow tube 20.

[0034] The inner wall of the treatment chamber is fixedly connected with a drainage pipe 45 which passes through the surface of the treatment box 4. The drainage pipe 45 is bent. The surface of the drainage pipe 45 is fixedly connected with a water storage shell 13. The surface of the water storage shell 13 is fixedly connected with a water inlet pipe 12 which passes through the surface of the water storage shell 13. The lower end of the water inlet pipe 12 does not contact the inner wall of the treatment chamber, so that the seawater in the treatment chamber can be smoothly injected into the water storage shell 13 through the water inlet pipe 12, which is convenient for the subsequent discharge of the reacted seawater.

[0035] One end of the drain pipe 45 located outside the treatment box 4 is rotatably connected to a rotating shaft 22 protruding from the surface of the drain pipe 45, and one end of the rotating shaft 22 located inside the drain pipe 45 is fixedly connected to a first turbine 21, so that the impact force of seawater when discharged can be used to drive the rotating shaft 22 to rotate, thereby providing partial power for the operation of the device, thereby achieving the energy-saving effect of the device. One end of the rotating shaft 22 located outside the drain pipe 45 is fixedly connected to a bevel gear 23, and the inner wall of the mounting groove 8 is rotatably connected to a driving rod 24 protruding from the surface of the treatment box 4. The surface of the driving rod 24 is also rotatably connected to the inside of the treatment box 4, and the end of the driving rod 24 located outside the treatment box 4 is also fixedly connected to the bevel gear 23, and the surfaces of the two bevel gears 23 are meshed with each other.

[0036] One end of the driving rod 24 located inside the mounting groove 8 is fixedly connected to a reciprocating screw rod 25, and the inner wall of the mounting groove 8 is slidably connected to two moving blocks 26, one moving block 26 is rotatably connected to the surface of the driving rod 24, and the other moving block 26 is threadedly connected to the surface of the reciprocating screw rod 25. Two moving blocks 26 are also provided at the bottom of the filter screen 7, one moving block 26 at the bottom of the filter screen 7 is fixedly connected to the bottom of the filter screen 7, and the other moving block 26 at the bottom of the filter screen 7 is slidably connected to the bottom of the filter screen 7, and two connecting rods 27 arranged in a cross manner are rotatably connected between the four moving blocks 26, and the two connecting rods 27 are rotatably connected to each other, thereby forming a scissor-type lifting mechanism, so that when the reciprocating screw rod 25 rotates, it can smoothly drive the filter screen 7 to rise and fall in the mounting groove 8.

[0037] A rack 31 is fixedly connected to the surface of the filter screen 7, and the surface of the rack 31 is slidably connected to the inner wall of the mounting groove 8. A brush roller 30 is rotatably connected to the inner wall of the mounting groove 8. The surface of the brush roller 30 is in contact with the surface of the filter screen 7 to sweep away the particulate matter on the surface of the filter screen 7. The brush roller 30 is coaxially fixedly connected to a gear 29, and the surface of the gear 29 is meshingly connected to the surface of the rack 31. A collecting box 28 is slidably connected to the inner wall of the mounting groove 8, and the collecting box 28 penetrates the surface of the processing box 4 and is slidably connected to the inside of the processing box 4, so that the staff can remove the impurities in the collecting box 28 by pulling out the collecting box 28.

[0038] Specifically, when in use, the exhaust gas in a heat storage chamber 2 is extracted by the suction fan and injected into the treatment box 4 through the connecting pipe 10, so that the exhaust gas enters the rotating pipe 17. When the exhaust gas enters the rotating pipe 17, it impacts the second turbine 42, thereby driving the rotating pipe 17 to rotate, thereby driving the first diverter pipe 33 and the second diverter pipe 39 to rotate. At the same time, the exhaust gas is diverted into the first diverter pipe 33 and the second diverter pipe 39 respectively, and discharged through the through holes in the second diverter pipe 39 and the mobile pipe 36, heating the flow pipe 20 and the seawater flowing therein. While the second diverter pipe 39 and the first diverter pipe 33 rotate, the first fixed shell 32 and the second fixed shell 33 are driven to rotate. The fixed shell 40 rotates, thereby driving the steel brush 37 to sweep the surface of the flow tube 20, thereby removing the particles attached to the surface of the flow tube 20. At the same time, the airflow generated when the exhaust gas is discharged blows the dust particles contaminated on the side surface of the flow tube 20 to remove the dust particles. When the movable shell 35 rotates to the horizontal connection of the flow tube 20, the surface of the flow tube 20 squeezes the inclined surface of the movable shell 35, thereby pushing the movable shell 35 to retract into the first fixed shell 32, so that the movable tube 36 retracts into the first diverter tube 33, and compresses the second spring 34, so that the movable shell 35 can smoothly pass through the horizontal connection of the flow tube 20, thereby ensuring the smooth operation of the device.

[0039] The rotating tube 17 drives the moving ring 15 to rotate while rotating, thereby driving the knocking plate 14 to rotate. When the knocking plate 14 contacts the protrusion 11, the protrusion 11 blocks the rotation path of the knocking plate 14. Therefore, under the obstruction of the protrusion 11, the knocking plate 14 moves along the inclined surface of the protrusion 11, thereby driving the moving ring 15 to approach the fixed ring 18 and compressing the return spring 19 between the fixed ring 18 and the moving ring 15. After the knocking plate 14 is separated from the protrusion 11, under the elastic force of the return spring 19, the moving ring 15 returns to its original state, thereby driving the knocking plate 14 to knock on the surface of the flow tube 20, thereby shaking off the dust particles on the surface of the flow tube 20 again, and removing the dust particles on the surface of the flow tube 20 by blowing, sweeping and vibrating, thereby avoiding the dust particles adhering to the surface of the flow tube 20 and affecting the device's utilization of waste heat from exhaust gas, thereby improving the device's effect on the utilization of waste heat from exhaust gas, which is worthy of promotion.

[0040] Then the exhaust gas is filtered through the filter 7 to intercept the dust particles contained in the exhaust gas. Then the exhaust gas enters the processing chamber through the filter 7 and is sprayed by the seawater discharged from the spray pipe 5 to desulfurize the exhaust gas. Then the exhaust gas and seawater are gradually discharged to the lower part of the processing chamber through the guide plate 44 between the two baffles 41. Then the treated exhaust gas is discharged through the discharge pipe 3, while the seawater is retained at the bottom of the processing chamber. As the seawater gradually accumulates at the bottom of the processing chamber, the water level of the seawater in the water inlet pipe 12 gradually increases. As the water level increases, the seawater is injected into the water storage shell 13 through the water inlet pipe 12, and the air in the water storage shell 13 is gradually discharged through the drain pipe 45. As the water level increases, the water level submerges the drain pipe 45, thereby sucking the water in the processing chamber under the action of the siphon until the water level in the processing chamber drops to a low level. At the lower end of the water inlet pipe 12, the discharged seawater impacts the first turbine 21, thereby driving the device shaft 22 to rotate, and through the meshing of two bevel gears 23, driving the driving rod 24 to rotate, and then driving the reciprocating screw 25 to rotate in the installation groove 8, thereby driving a moving block 26 to reciprocate in the installation groove 8, and then driving the filter screen 7 to reciprocate and lift in the installation groove 8 through the connecting rod 27. During the lifting process of the filter screen 7, the rack 31 is driven to move, and through the meshing with the gear 29, the brush roller 30 is driven to rotate, brushing the surface of the filter screen 7, and brushing away the dust particles on the surface of the filter screen 7, avoiding the dust particles clogging the filter screen 7 and affecting the flow of exhaust gas, and the swept dust particles are received and collected by the collecting box 28, which is convenient for subsequent staff to deal with them.

[0041] Working principle: When in use, the exhaust gas in a heat storage chamber 2 is extracted by the suction fan and injected into the treatment box 4 through the connecting pipe 10, so that the exhaust gas enters the rotating pipe 17, driving the rotating pipe 17 to rotate, and the exhaust gas is diverted and discharged through the second diverter pipe 39 and the through hole in the moving pipe 36, heating the seawater flowing inside the flow pipe 20, and using the steel brush 37 to sweep the surface of the flow pipe 20 to sweep away the particles attached to the surface of the flow pipe 20. At the same time, the airflow generated when the exhaust gas is discharged removes the dust particles contaminated on the side surface of the flow pipe 20. The dust particles are blown away, and the rotating tube 17 drives the moving ring 15 to rotate while rotating, thereby driving the knocking plate 14 to rotate. Under the obstruction of the protrusion 11, the knocking plate 14 moves along the inclined surface of the protrusion 11, thereby driving the moving ring 15 to approach the fixed ring 18, and compressing the return spring 19 between the fixed ring 18 and the flow tube 20. After the knocking plate 14 is separated from the protrusion 11, under the elastic force of the return spring 19, the knocking plate 14 is driven to knock on the surface of the flow tube 20, and the dust particles on the surface of the flow tube 20 are shaken off again.

[0042] Then, the exhaust gas enters the processing chamber through the filtration of the filter 7, and is sprayed by the seawater discharged from the spray pipe 5. Then, the treated exhaust gas is discharged through the discharge pipe 3, and the seawater is retained at the bottom of the processing chamber. As the seawater gradually accumulates at the bottom of the processing chamber, under the action of siphon, the drain pipe 45 sucks the water in the processing chamber, and the discharged seawater impacts the first turbine 21, thereby driving the driving rod 24 to rotate, driving the filter 7 to reciprocate and rise and fall in the mounting groove 8, and through the rotation of the brush roller 30, the surface of the filter 7 is brushed to brush away the dust particles on the surface of the filter 7, thereby preventing the dust particles from clogging the filter 7.

[0043] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
