Description

Technical Field

[0001] The utility model relates to the technical field of furnace flue gas filtration and dust removal equipment, and specifically relates to a furnace flue gas filtration and dust removal device. Background Technique

[0002] To ensure the safety of the air environment, it is often necessary to filter and remove dust from furnace flue gas, and thus it is necessary to use furnace flue gas filtration and dust removal equipment. The utility model patent with the patent application number CN201921852111.X discloses an industrial furnace flue gas particle filtration device. By setting a fan, the flue gas to be filtered can enter the first filter box, which better ensures the completion of the filtration process. By setting micropores, the contact area between the flue gas and the filtrate can be increased, which better ensures the filtration quality. By setting a sewage discharge pipe, the filtered filtrate can be discharged in time, which can ensure the sustainable use of the equipment. According to the disclosed technical solution, when the existing furnace flue gas filtration and dust removal equipment is in use, on the one hand, the flue gas often contains a lot of heat, which not only causes waste of heat but also easily damages the filtration mechanism due to high temperature. On the other hand, when recovering the waste heat of the flue gas, the waste heat recovery rate is easily reduced due to too fast wind speed, or the dust removal rate of the flue gas is reduced due to too low wind speed. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a furnace flue gas filtration and dust removal device to solve the problems raised in the above background technique. The utility model can avoid reducing the heat exchange efficiency of the conduit due to dust adhesion and can adjust the flow rate of the flue gas to improve the reliability of the device.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A furnace flue gas filtration and dust removal device includes a bag filter and a conduit. A cooling component is installed on the outer side of the conduit. The cooling component includes a ferrule and an inlet pipe. A cleaning component is installed on the conduit. The cleaning component includes a screw plate and a motor. A connecting component is installed on the conduit. The connecting component includes a connecting pipe and a collar. A movable component is installed on the collar. The movable component includes a sleeve and a piston. An electric control component is installed inside the sleeve. The electric control component includes a button one and a button two.

[0005] Further, both ends of the ferrule are welded to the outer sides of both ends of the conduit, and brackets are welded to both the ferrule and the bottom of the bag filter.

[0006] Further, the inlet pipe is welded to the bottom of one end of the ferrule, and an outlet pipe is welded to the top of the other end of the ferrule.

[0007] Further, one end of the connecting pipe is welded to the other end of the conduit, and the other end of the connecting pipe is welded to one side of the bag filter.

[0008] Further, the outer side of the spiral plate is stuck on the inner wall of the conduit, the motor is installed on the outer side of the connecting pipe through bolts, a support rod is welded on the spiral plate, and the output shaft of the motor passes through the connecting pipe through a sealing ring and is welded on the support rod.

[0009] Further, the collar is welded on the outer side of the connecting pipe, the sleeve is welded on one side of the collar, and the piston is stuck inside the sleeve.

[0010] Further, both the first button and the second button are installed inside the sleeve through bolts, and the first button and the second button are respectively located on both sides of the piston.

[0011] Further, a discharge pipe is welded on the top of the bag filter, an electric valve is installed at one end of the conduit, and both the first button and the second button are connected to the electric valve through wires.

[0012] Beneficial effects:

[0013] 1. When the furnace flue gas filtration and dust removal device is in use, the furnace flue gas is introduced into the inner side of the conduit, water is introduced through the inlet pipe, the water absorbs the heat of the furnace flue gas in the conduit in the clamping sleeve, and the hot water flows out through the outlet pipe, effectively recovering the waste heat of the furnace flue gas, reducing heat waste, and at the same time reducing the temperature of the furnace flue gas, avoiding damage to the bag filter caused by high temperature, ensuring the safety of the bag filter. The motor drives the spiral plate to rotate through the support rod to clean the inner wall of the conduit, avoiding reduction of the heat exchange efficiency of the conduit due to dust adhesion. The cooled furnace flue gas enters the bag filter through the connecting pipe, and after being filtered and dust removed by the bag filter, it is discharged outward through the discharge pipe.

[0014] 2. When the furnace flue gas filtration and dust removal device is in use, after the furnace flue gas is cooled and enters the inner side of the connecting pipe, if the temperature is still very high, the air in the collar expands, the air pressure pushes the piston to the left and presses the first button, and the first button controls the electric valve to reduce the opening of the conduit, thereby reducing the wind speed, so that the furnace flue gas has enough time to perform heat exchange work in the conduit, ensuring the heat recovery efficiency. If the temperature of the furnace flue gas in the connecting pipe is relatively low, the air in the collar shrinks, attracts the piston to the right, and presses the second button. The second button controls the electric valve to increase the opening of the conduit, thereby increasing the flow rate of the furnace flue gas and improving the working efficiency of filtering and dust removing the furnace flue gas.

[0015] 3. The furnace flue gas filtration and dust removal device is reasonably designed, is relatively efficient and convenient to use, and is suitable for filtering and dust removing of furnace flue gas. Description of the drawings

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3, the utility model provides a technical solution: a furnace flue gas filtration and dust removal device, which includes a bag filter 1 and a conduit 2. A cooling component is installed on the outer side of the conduit 2. The cooling component includes a ferrule 3 and an inlet pipe 6. A cleaning component is installed on the conduit 2. The cleaning component includes a screw plate 7 and a motor 8. A connecting component is installed on the conduit 2. The connecting component includes a connecting pipe 10 and a collar 11. An actuating component is installed on the collar 11. The actuating component includes a sleeve 12 and a piston 13. An electric control component is installed inside the sleeve 12. The electric control component includes a button one 14 and a button two 15. The outer side of the screw plate 7 is stuck on the inner wall of the conduit 2. The motor 8 is installed on the outer side of the connecting pipe 10 through bolts. A support rod 9 is welded on the screw plate 7. The output shaft of the motor 8 passes through the connecting pipe 10 through a seal ring and is welded on the support rod 9. A discharge pipe 17 is welded on the top of the bag filter 1. An electric valve 16 is installed at one end of the conduit 2. The button one 14 and the button two 15 are both connected to the electric valve 16 through wires. When in use, the furnace flue gas is introduced into the inside of the conduit 2, and water is introduced through the inlet pipe 6. The water absorbs the heat of the furnace flue gas in the conduit 2 inside the ferrule 3. The hot water flows out through the outlet pipe 5. The waste heat of the furnace flue gas is effectively recovered, reducing heat waste. At the same time, the temperature of the furnace flue gas is reduced, avoiding damage to the bag filter 1 caused by high temperature and ensuring the safety of the bag filter 1. The motor 8 drives the screw plate 7 to rotate through the support rod 9 to clean the inner wall of the conduit 2, avoiding the reduction of the heat exchange efficiency of the conduit 2 due to dust adhesion. The cooled furnace flue gas enters the bag filter 1 through the connecting pipe 10. After being filtered and dust removed by the bag filter 1, it is discharged outward through the discharge pipe 17.

[0022] In this embodiment, both ends of the ferrule 3 are welded to the outer sides of both ends of the conduit 2. Brackets 4 are welded to both the ferrule 3 and the bottom of the bag filter 1. The inlet pipe 6 is welded to the bottom of one end of the ferrule 3, and the outlet pipe 5 is welded to the top of the other end of the ferrule 3. One end of the connecting pipe 10 is welded to the other end of the conduit 2, and the other end of the connecting pipe 10 is welded to one side of the bag filter 1. The collar 11 is welded to the outer side of the connecting pipe 10, and the sleeve 12 is welded to one side of the collar 11. The piston 13 is stuck inside the sleeve 12. The button one 14 and the button two 15 are both installed inside the sleeve 12 by bolts. The button one 14 and the button two 15 are respectively located on both sides of the piston 13. When in use, after the furnace flue gas is cooled down and enters the inside of the connecting pipe 10, if the temperature is still very high, the air inside the collar 11 expands, and the air pressure pushes the piston 13 to the left and presses the button one 14. The button one 14 controls the electric valve 16 to reduce the opening degree of the conduit 2, thereby reducing the wind speed, so that the furnace flue gas has enough time to perform heat exchange work inside the conduit 2, ensuring the heat recovery efficiency. If the temperature of the furnace flue gas inside the connecting pipe 10 is relatively low, the air inside the collar 11 contracts, attracting the piston 13 to the right and pressing the button two 15. The button two 15 controls the electric valve 16 to increase the opening degree of the conduit 2, thereby increasing the flow rate of the furnace flue gas and improving the working efficiency of filtering and dust removal of the furnace flue gas.

[0023] The furnace flue gas filtering and dust removal device provides electrical energy for all electrical equipment through an external power supply. When in use, the furnace flue gas is introduced into the inside of the conduit 2, and water is introduced through the inlet pipe 6. The water absorbs the heat of the furnace flue gas inside the conduit 2 inside the ferrule 3, and the hot water flows out through the outlet pipe 5, effectively recovering the waste heat of the furnace flue gas, reducing heat waste, and at the same time reducing the temperature of the furnace flue gas, avoiding damage to the bag filter 1 caused by high temperature, and ensuring the safety of the bag filter 1. The motor 8 drives the screw plate 7 to rotate through the support rod 9 to clean the inner wall of the conduit 2, avoiding reducing the heat exchange efficiency of the conduit 2 due to dust adhesion. The cooled furnace flue gas enters the bag filter 1 through the connecting pipe 10, and after being filtered and dust removed by the bag filter 1, it is discharged outward through the exhaust pipe 17. After the furnace flue gas is cooled down and enters the inside of the connecting pipe 10, if the temperature is still very high, the air inside the collar 11 expands, and the air pressure pushes the piston 13 to the left and presses the button one 14. The button one 14 controls the electric valve 16 to reduce the opening degree of the conduit 2, thereby reducing the wind speed, so that the furnace flue gas has enough time to perform heat exchange work inside the conduit 2, ensuring the heat recovery efficiency. If the temperature of the furnace flue gas inside the connecting pipe 10 is relatively low, the air inside the collar 11 contracts, attracting the piston 13 to the right and pressing the button two 15. The button two 15 controls the electric valve 16 to increase the opening degree of the conduit 2, thereby increasing the flow rate of the furnace flue gas and improving the working efficiency of filtering and dust removal of the furnace flue gas.
