Description

Technical Field

[0001] The present invention relates to the technical field of zinc fume dust collectors, and particularly to an energy-saving and environment-friendly zinc fume dust collector. Background Art

[0002] Harmful gases in hot-dip galvanizing production are highly hazardous. Flue gas dust, also known as zinc fume, has a high concentration, is fine and light. It mainly consists of zinc dust (zinc oxide) flue gas generated during hot-dip galvanizing and ammonium chloride gas emitted when solvents (ammonium chloride, zinc chloride) are heated. Such dust seriously affects the working environment and can also cause corrosion problems to the plant and equipment. Therefore, in order to make the production environment safer, it is necessary to use environmental protection equipment to remove dust from zinc fume;

[0003] When removing dust from zinc fume, a common dust removal device is a bag filter. The temperature of zinc fume is relatively high. Even after being treated by the dust collector, a large amount of heat is still carried in the relatively clean air discharged. If this high-temperature gas is directly discharged into the atmosphere, it will undoubtedly waste a large amount of energy;

When the high-temperature gas passes through the spiral pipe part of the air guide pipe, the heat in the gas can make the spiral pipe act as a heater, which can heat the water in the first chamber to realize the full utilization of waste heat. Subsequently, the discharged gas will be washed by water in the second chamber and finally discharged into the atmosphere. This process makes the waste heat energy fully utilized, more energy-saving and environment-friendly;

[0016] 2. The water in the first chamber is stirred in multiple directions by the flowing water device to make it flow, so that the water can fully contact the outer wall of the spiral tube. Without heat transfer in the water to achieve overall heating, the water can be directly heated. Coupled with the shape of the spiral tube, the contact area with water can be greatly increased, thus effectively improving the water heating efficiency.

[0017] 3. When the gas is discharged from the L-shaped air outlet pipe to the atmosphere, it can blow the fan blades to rotate, so that the output shaft of the generator rotates, and then the purpose of wind power generation is achieved. After the power generation is stored, it can be used as a standby. This power generation method is pollution-free, more energy-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Embodiment, consisting of Figure 1-7Given that, the present invention includes a bag filter main body 1. A box body 2 is installed on one side of the bag filter main body 1. A partition plate 3 is fixedly connected inside the box body 2. The partition plate 3 divides the interior of the box body 2 into a first chamber 4 and a second chamber 5. The first chamber 4 is located on one side of the second chamber 5. The air outlet of the bag filter main body 1 is fixedly connected with a duct. The duct is located on one side of the box body 2 and extends into the first chamber 4 and the second chamber 5. A live water device is installed inside the first chamber 4. The top of the box body 2 is fixedly connected with an L-shaped air outlet pipe 11. The L-shaped air outlet pipe 11 is communicated with the inside of the second chamber 5.

[0027] The duct is composed of a spiral pipe 6, a first connecting pipe 7 and a second connecting pipe 8. The spiral pipe 6 is fixedly connected inside the first chamber 4, and both ends of the spiral pipe 6 extend out of the top and bottom of the box body 2 respectively. The first connecting pipe 7 is fixedly connected to the bottom of the spiral pipe 6, and the end of the first connecting pipe 7 away from the spiral pipe 6 is fixedly connected to the air outlet of the bag filter main body 1. The second connecting pipe 8 is fixedly connected to the top of the spiral pipe 6. The second connecting pipe 8 is located above the box body 2 and extends into the second chamber 5. The spiral pipe 6 is in direct contact with water inside the first chamber 4. When high-temperature air flows through the spiral pipe 6, the spiral pipe 6 is equivalent to a heater, so that the water in the first chamber 4 can be heated. This process can not only cool the high-temperature air discharged after zinc fume dust removal, but also make full use of its residual heat to achieve the purpose of energy conservation and emission reduction. The spiral shape of the spiral pipe 6 makes its contact area with water larger, and at the same time, it can also make the hot air stay in the first chamber 4 for a longer time to fully carry out heat replacement.

[0028] A flow dividing plate 10 is fixedly connected to the inner side wall of the second chamber 5. The end of the second connecting pipe 8 is fixedly connected with a wind dispersing cover 9. The flow dividing plate 10 is located above the wind dispersing cover 9. The gas discharged from the duct is shunted multiple times through the wind dispersing cover 9 and the flow dividing plate 10, so that the gas can form smaller and denser bubbles and float in the water in the second chamber 5, thereby increasing the contact area between the gas and the water. This process can further reduce the gas temperature, and at the same time, it can also clean the gas, adsorb the remaining impurities in the gas, etc., making the discharged gas cleaner.

[0029] A generator 12 is fixedly connected to the top of the L-shaped air outlet pipe 11. The output shaft of the generator 12 is fixedly connected with a fan blade 13. The fan blade 13 is located inside the L-shaped air outlet pipe 11. When discharging the gas into the atmosphere, wind power generation can be carried out through the cooperation of the generator 12 and the fan blade 13, further improving the resource utilization rate, and wind power generation is more environmentally friendly. The wind power generation principle of the generator 12, as well as the equipment and related principles required for power generation and storage are all prior arts, so they will not be elaborated here too much.

[0030] The living water device includes a rotating rod 14, which is movably connected to the inside of the first chamber 4 and is located on the inner side of the spiral tube 6. Two propellers 15 are fixedly connected to the outer end of the rotating rod 14. The bottom of the rotating rod 14 passes through the box body 2 and extends to the bottom of the box body 2. A motor 16 is fixedly connected to the bottom of the box body 2. The output shaft of the motor 16 and the outer end of the rotating rod 14 are fixedly connected with a bevel gear 17. The two bevel gears 17 are meshed with each other. When the propeller 15 rotates, the water in the first chamber 4 can be stirred vertically.

[0031] The living water device also includes two shells 21, and the two shells 21 are respectively fixedly connected to the diagonals on the front and rear side walls inside the first chamber 4. A plurality of rotating rods 3 23 are movably connected inside the shell 21, and the front side of the rotating rod 3 23 extends to the front of the shell 21. The front side of the rotating rod 3 23 is fixedly connected to a stirring paddle 24. The bottom of the shell 21 is movably connected to a rotating rod 22, and the rotating rod 22 is located inside the first chamber 4 and extends to the bottom of the box body 2. The bottom of the rotating rod 22 is fixedly connected to a single-track pulley 1 20, and the bottom of the rotating rod 14 is fixedly connected to a double-track pulley 18. The double-track pulley 18 and the single-track pulley 1 20 are connected to each other through a belt 19 Then, the top of the rotating rod 22 and the outer end of an adjacent rotating rod 3 23 are fixedly connected with a bevel gear 25, and the two bevel gears 25 are meshed with each other. Multiple rotating rods 3 23 are fixedly connected with a monorail pulley 26, and the upper and lower adjacent monorail pulleys 26 are connected to each other through a belt 27. The position of the stirring paddles 24 on the two shells 21 enables them to stir the water in the first chamber 4 laterally during operation. There are three rotating rods 3 23, and there are two monorail pulleys 26 on the middle rotating rod 3 23, so that adjacent rotating rods 3 23 can be connected to each other through the monorail pulley 26 and the belt 2 27.

[0032] The active water device can stir the water in the first chamber 4 in both vertical and horizontal directions to improve the water activity, thereby enabling the spiral tube 6 to fully heat the water in the first chamber 4 .

[0033] A temperature sensor 28 is fixedly connected to the inner wall of the first chamber 4, and a pressure relief pipe 33 is fixedly connected to the top side of the box body 2. The pressure relief pipe 33 is connected to the inside of the first chamber 4. The temperature sensor 28 can detect the water temperature in the first chamber 4 in real time. When the water temperature gradually rises, if the first chamber 4 is in a sealed state, the internal air pressure will gradually increase. Therefore, the setting of the pressure relief pipe 33 can relieve the pressure of the first chamber 4.

[0034] A water inlet pipe 1 (29) , a drain pipe 1 (30) , a water inlet pipe 2 (31) and a drain pipe 2 (32) are fixedly connected to the rear side of the box body 2. The water inlet pipe 1 (29) and the drain pipe 1 (30) are internally communicated with the first chamber 4. The water inlet pipe 2 (31) and the drain pipe 2 (32) are internally communicated with the second chamber 5. The water inlet pipe 1 (29) is located above the drain pipe 1 (30). The water inlet pipe 2 (31) is located above the drain pipe 2 (32). Solenoid valves are installed on the water inlet pipe 1 (29) , the drain pipe 1 (30) , the water inlet pipe 2 (31) and the drain pipe 2 (32). Corresponding to the water in the first chamber 4, when the water temperature reaches the required temperature, such as the boiling state at 100 degrees Celsius, the water can be drained through the drain pipe 1 (30) , and then cold water can be added to the first chamber 4 through the water inlet pipe 1 (29). Specifically, the opening and closing times of each solenoid valve are remotely controlled by a control terminal. The specific control method can be wired or wireless connection. For the control terminal capable of controlling the solenoid valve, as well as its wiring method and electrical connection principle, they are all prior arts, so they will not be elaborated here too much.

[0035] Working principle:

[0036] First, the zinc fume is dust-removed by the main body 1 of the bag filter, and then relatively clean but high-temperature gas is discharged. The gas enters the inside of the spiral pipe 6 through the connecting pipe 1 (7). When high-temperature gas flows through the spiral pipe 6, the spiral pipe 6 is equivalent to a heater, which can heat the water in the first chamber 4. At the same time, the temperature of the flowing high-temperature gas will also be reduced by a part. Then the gas continues to flow into the connecting pipe 2 (8) and finally is discharged into the water in the second chamber 5 through the air distribution hood 9. The gas discharged from the air distribution hood 9 will be divided into multiple bubbles. Then, when the bubbles float upward, they will be shunted by the shunt plate 10 and form smaller bubbles to float upward again. When the gas floats upward, its heat will be further cooled by the water in the second chamber 5, and at the same time, the discharged gas will be scrubbed to improve the cleanliness of the discharged gas. Then the gas with no longer high temperature floats upward and is discharged from the L-shaped air outlet pipe 11. When the gas flows through the L-shaped air outlet pipe 11, it will blow the fan blade 13 to rotate. When the fan blade 13 rotates, it drives the output shaft of the generator 12 to rotate, so that the generator 12 can generate electricity.

[0037] When the spiral tube 6 is used as a heater to heat the water in the first chamber 4, during this period, the water inside the first chamber 4 can be made to fully contact the outer surface of the spiral tube 6 through the water circulation device, thereby increasing the heating speed of the water. Specifically, the motor 16 can be started. The output shaft of the motor 16 drives the first rotating rod 14 to rotate through the meshing transmission of two first bevel gears 17. When the first rotating rod 14 rotates, it can drive the first propeller 15 to rotate. The first propeller 15 can stir the water in the first chamber 4 vertically up and down. At the same time, when the first rotating rod 14 rotates, it will also drive the second rotating rod 22 to rotate through the transmission of the double-track pulley 18, the first belt 19 and the single-track pulley 20. When the second rotating rod 22 rotates, it can drive an adjacent third rotating rod 23 to rotate through the meshing transmission of two second bevel gears 25. Subsequently, the adjacent third rotating rod 23 drives all the third rotating rods 23 to rotate synchronously through the transmission of the single-track pulley 26 and the second belt 27. When the third rotating rod 23 rotates, it can drive the second stirring paddle 24 to rotate. The positions of the second stirring paddles 24 on the two shells 21 enable them to stir the water in the first chamber 4 horizontally during operation. The water circulation device can stir the water in the first chamber 4 in both the vertical and horizontal directions to improve the water activity, thereby enabling the spiral tube 6 to fully heat the water in the first chamber 4.
