Description

Technical Field

[0001] This utility model belongs to the field of scrubbing tower technology, and in particular relates to an energy-saving and efficient furnace gas scrubbing tower. Background Technology

[0002] Furnace gas is mainly the gas produced during fuel combustion in industrial furnaces and kilns. Its main components are a certain amount of pollutants such as sulfides, nitrogen oxides, and unburned carbon particles. Among them, sulfides and nitrogen oxides are the main substances that cause acid rain, while unburned carbon particles will exacerbate the greenhouse effect and air pollution. Therefore, furnace gas needs to be washed to remove pollutants before being emitted. Generally, a scrubbing tower is used to wash the furnace gas.

[0003] Traditional scrubbing towers typically use direct spraying of atomized water to wash furnace gas. However, the droplets are large and have poor uniformity, resulting in limited contact area between the droplets and impurities in the furnace gas, incomplete reaction, poor washing effect, and the need for multiple washes. This leads to a large water consumption, and the increased number of washes raises the moisture content of the furnace gas. Traditional scrubbing towers also lack an effective heat recovery mechanism, requiring more heat energy for the subsequent drying process. Furthermore, the traditional furnace gas scrubbing process involves collecting the gas after washing and then drying it, which is discontinuous, requires numerous equipment and steps, and is inefficient. Utility Model Content

[0004] The purpose of this invention is to propose an energy-saving and efficient furnace gas scrubbing tower to solve the problems of insufficient atomization leading to high energy consumption and discontinuous scrubbing process during furnace gas scrubbing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving and efficient furnace gas scrubbing tower, comprising a base, an air inlet pipe connected to one side of the base, a fan and a pretreatment mechanism inside the base, the pretreatment mechanism comprising an insulation shell disposed on the top of the base, a filter plate disposed at the bottom of the insulation shell, a heat storage cavity formed between the inner and outer walls of the insulation shell, and multiple water injection chambers arranged around the heat storage cavity along the axis; wherein, the scrubbing mechanism comprises a pressure-resistant shell disposed on the top of the insulation shell, multiple nozzles arranged around the inner wall of the pressure-resistant shell along the axis, one end of each nozzle connected to a water distribution pipe disposed between the outer and inner walls of the pressure-resistant shell, and interception plates disposed on both sides of each nozzle, one side of which is fixedly connected to the inner wall of the pressure-resistant shell.

[0006] Preferably, the top of the inner wall of the water injection chamber is connected to the bottom of the water distribution pipe, and a water inlet pipe is connected to one side of the inner wall of the water injection chamber.

[0007] Preferably, the washing mechanism further includes a support plate connected to the top of the pressure-resistant shell. The top of the support plate has multiple ventilation holes circumferentially arranged along the axis. The bottom of the support plate is rotatably connected to a connecting column. The outer wall of the connecting column is provided with multiple rotating blades circumferentially arranged along the axis. A motor is fixedly installed on the top of the support plate. The output end of the motor is fixedly connected to one end of the connecting column. A protective cover is fitted over the motor. The bottom of the protective cover is fixedly connected to the top of the support plate.

[0008] Preferably, the top of the pressure-resistant shell is provided with a drying mechanism, the drying mechanism includes a heat insulation shell, the inner wall of the heat insulation shell is provided with a plurality of heat-releasing pipes arranged around the axis, the outer wall of the heat insulation shell is provided with a plurality of heaters arranged around the axis, the positions of the heaters correspond to the positions of the heat-releasing pipes, and the top of the heat insulation shell is connected to an air outlet pipe.

[0009] Preferably, the inner wall of the heat storage cavity is connected to a heat-conducting pipe, the top of the heat insulation shell is provided with multiple through holes, the top end of the heat-conducting pipe passes through the through holes, and a heat collection block is fixedly connected to the top end of the heat-conducting pipe.

[0010] Preferably, the heat collection block is disposed inside the heat insulation shell, and the outer wall of the heat collection block is provided with multiple heat collection grooves along the axis.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. In this utility model, a portion of the heat during the drying of the furnace gas is recovered by the heat collection block, and then the heat is transported to the heat storage chamber by the heat conduction pipe for storage. The stored heat is used to preheat the water, which improves the atomization effect during the first atomization. Then, the small droplets are dispersed by the swirl blades for secondary atomization, so that the droplets come into more thorough contact with the impurities in the furnace gas, thereby making the furnace gas washing more complete. The recycled heat reduces the energy consumption of the washing tower, and the secondary atomization enhances the washing effect.

[0013] 2. In this utility model, a fan is used to push the furnace gas upward. By setting up a multi-stage mechanism, the furnace gas is first filtered to remove large particulate impurities, reducing the difficulty of washing. At the same time, the furnace gas is washed by secondary atomization in the washing mechanism, making the washing more thorough and the washing effect better. The water-containing furnace gas after washing is directly dried during its upward discharge from the washing tower, eliminating the step of collecting the washing gas and then drying it, making the washing process more continuous, simple, and efficient.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: an energy-saving and efficient furnace gas scrubbing tower, including a base 1, an air inlet pipe 2 connected to one side of the base 1, and a fan 3 installed inside the base 1;

[0021] Pretreatment mechanism 4 includes a heat insulation shell 401 set on the top of the base 1, a filter plate 405 set at the bottom of the heat insulation shell 401, a heat storage cavity 402 opened between the inner wall and the outer wall of the heat insulation shell 401, and multiple water injection chambers 403 arranged around the heat storage cavity 402 along the axis.

[0022] The washing mechanism 5 includes a pressure-resistant shell 501 mounted on top of the insulation shell 401. Multiple nozzles 503 are arranged around the inner wall of the pressure-resistant shell 501 along its axis. One end of each nozzle 503 is connected to a water distribution pipe 502, which is positioned between the outer and inner walls of the pressure-resistant shell 501. An intercepting plate 504 is mounted on both sides of each nozzle 503, with one side of the intercepting plate 504 fixedly connected to the inner wall of the pressure-resistant shell 501.

[0023] The top of the inner wall of the water injection chamber 403 is connected to the bottom of the water distribution pipe 502, and a water inlet pipe 404 is connected to one side of the inner wall of the water injection chamber 403.

[0024] The washing mechanism 5 also includes a support plate 505 connected to the top of the pressure-resistant shell 501. The top of the support plate 505 has multiple ventilation holes 506 circumferentially arranged along the axis. The bottom of the support plate 505 is rotatably connected to a connecting column 507. The outer wall of the connecting column 507 is provided with multiple rotating blades 508 circumferentially arranged along the axis. A motor 509 is fixedly installed on the top of the support plate 505. The output end of the motor 509 is fixedly connected to one end of the connecting column 507. A protective cover 510 is fitted over the motor 509. The bottom of the protective cover 510 is fixedly connected to the top of the support plate 505.

[0025] The inner wall of the heat storage cavity 402 is connected to a heat-conducting pipe 7. The top of the heat insulation shell 601 has multiple through holes. The top of the heat-conducting pipe 7 passes through the through holes, and a heat collection block 8 is fixedly connected to the top of the heat-conducting pipe 7.

[0026] The heat collection block 8 is located inside the heat insulation shell 601, and multiple heat collection grooves are formed around the outer wall of the heat collection block 8 along the axis.

[0027] Specifically, heater 603 heats heat-dissipating pipe 602. Multiple heat-dissipating pipes 602 surrounding the inner wall of insulation shell 601 work together to raise the temperature inside insulation shell 601. Heat-collecting block 8, connected to the top of heat-conducting pipe 7, extends into insulation shell 601. Multiple heat-collecting grooves on the outer wall of heat-collecting block 8 significantly increase the contact area between heat-collecting block 8 and the air inside insulation shell 601. Heat-collecting block 8 absorbs some of the heat inside insulation shell 601 and conducts it to heat-conducting pipe 7. The bottom end of heat-conducting pipe 7 is connected to the inner wall of heat storage chamber 402. Heat is conducted along heat-conducting pipe 7 to heat storage chamber 402. The outer wall of water injection tank 403 inside heat storage chamber 402 is also made of copper. Water is injected into water injection tank 403 from water inlet pipe 404. The heat stored in heat storage chamber 402... The water in the water injection chamber is preheated to improve the atomization effect. After the water injection chamber 403 is filled with water, the preheated water enters the water distribution pipe 502 from the top of the water injection chamber 403. The preheated water flows from the water distribution pipe 502 into the nozzle 503 and then sprays out from the spray hole on the outer wall of the nozzle 503. After the preheated water is sprayed out, it is intercepted by the interception plates 504 set on both sides. The impact force disperses the preheated water into small droplets, completing the first atomization. The motor 509 drives the connecting column 507 to rotate. The swivel blade 508 connected to the outer wall of the connecting column 507 rotates synchronously with the connecting column 507. The swivel blade 508 hits the small droplets to make them more dispersed, completing the second atomization. At the same time, the rotation of the swivel blade 508 agitates the air inside the pressure-resistant shell 501, making it easier for the small droplets to combine with the impurity molecules in the furnace gas, resulting in a better washing effect.

[0028] It should be noted that, as described above, the viscosity and surface tension of water decrease after preheating, and its fluidity increases, making it easier to be sheared or broken into fine droplets. At the same time, the increase in internal vapor pressure will assist in droplet splitting. These changes directly promote the improvement of atomization effect. This part is a well-known technology in the field and will not be elaborated here.

[0029] It should be noted that the selection of motor 509 and control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0030] The top of the pressure-resistant shell 501 is provided with a drying mechanism 6. The drying mechanism 6 includes a heat insulation shell 601. Multiple heat-releasing pipes 602 are arranged around the inner wall of the heat insulation shell 601 along the axis. Multiple heaters 603 are arranged around the outer wall of the heat insulation shell 601 along the axis. The positions of the heaters 603 correspond to the positions of the heat-releasing pipes 602. The top of the heat insulation shell 601 is connected to an air outlet pipe 9.

[0031] Specifically, the furnace gas to be washed enters the base 1 through the air inlet pipe 2. The fan 3 pushes the furnace gas to float upwards. The rising furnace gas passes through the filter plate 405 of the pretreatment mechanism 4. The filter holes on the filter plate 405 filter out larger impurities in the furnace gas. The furnace gas continues to rise into the pressure-resistant shell 501 of the washing mechanism 5. The preheated hot water droplets inside the pressure-resistant shell 501 combine with the impurities in the furnace gas to wash the furnace gas. The washed water-containing furnace gas continues to rise and enters the heat insulation shell 601 of the drying device through the air vent 506. The heater 603 heats the heat release pipe 602. The heat release pipe 602 is made of copper. The heat release pipe 602 releases heat, which raises the temperature inside the heat insulation shell 601, thereby evaporating the moisture in the furnace gas. Some of the heat inside the heat insulation shell 601 is absorbed by the heat collection block 8 and conducted to the heat conduction pipe 7. It then enters the heat storage chamber 402 along the heat conduction pipe 7 for storage and is used to preheat the water. The furnace gas after washing and drying is discharged from the air outlet pipe 9.

[0032] It should be noted that the selection of fan 3 and control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0033] It should be noted that the heat pipe 602, the heat collector 8 and the heat pipe 7 mentioned above are all made of copper. Copper has high thermal conductivity and uniform heat conduction, and is often used in scenarios that require rapid heat conduction. This part is a well-known technology in the field and will not be elaborated here.

[0034] It should be noted that the heating principle of the heat-generating tube 602 described above is based on the Joule heating effect generated when current passes through the resistance wire, which converts electrical energy into heat energy and transfers it to the surface of the metal pipe through the heat-conducting material to heat the air. This part is a well-known technology in the field and will not be described in detail here.

[0035] It should be noted that the heater 603 mentioned above includes a heating unit, a temperature-sensitive element, and a thermostat, etc. This part is well-known technology in the field and will not be described in detail here.

[0036] Working principle: When in use, the operator first turns on the water pipe to fill the water filling tank 403 with water, then turns off the water pipe and turns on the heater 603 to raise the internal temperature of the drying unit 6 and preheat the water in the water filling tank 403. After a period of time, the operator turns on the fan 3 to introduce the furnace gas to be washed into the washing tower from the air inlet pipe 2. Then the water pipe is turned on continuously. After the washing furnace gas completes a series of washing processes from the bottom to the top of the washing tower, it is discharged from the air outlet pipe 9. The operator then recovers the washed furnace gas.
