Description

Technical Field

[0001] This utility model relates to the field of flue gas cooling and recovery technology, and in particular to a continuous carbonization flue gas cooling and recovery device. Background Technology

[0002] High-temperature flue gas typically refers to the hot gases produced during combustion, with temperatures generally exceeding 300°C. This high temperature can impose a heat load on downstream equipment and may even cause damage. Using a flue gas cooler to reduce the flue gas temperature to a reasonable range can protect downstream equipment from high-temperature damage and extend its service life.

[0003] In existing cooling devices, the flue gas enters the pipe to exchange heat and dissipate heat when cooling the flue gas. However, since the flue gas contains a lot of dust, it will adhere to the inner wall of the pipe after long-term use. When a lot of dust accumulates, it will reduce the heat transfer and absorption between the pipe and the cold water, thus affecting the cooling effect of the flue gas. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a continuous carbonized flue gas cooling and recovery device, which aims to improve the problem that the flue gas contains a lot of dust, which will adhere to the inner wall of the pipe after long-term use and affect the cooling effect of the flue gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous carbonization flue gas cooling and recovery device, comprising a recovery box, an air inlet pipe on the recovery box, a partition plate installed inside the recovery box, the partition plate dividing the inside of the recovery box into a filtration cavity and a cooling cavity, a plurality of filter screens in the filtration cavity of the recovery box, and a heat dissipation coil installed in the cooling cavity of the recovery box, the two ends of the heat dissipation coil being fixedly installed on the partition plate and the recovery box respectively, an agitation mechanism for stirring cold water in the cooling cavity of the recovery box, a water inlet pipe on the cooling cavity of the recovery box, and drain pipes installed in both the cooling cavity and the filtration cavity of the recovery box.

[0006] Preferably, the agitation mechanism includes multiple agitator rods fixedly installed in the cooling cavity of the recycling tank, multiple agitator blades fixed on the outer surface of the agitator rods, a motor fixed on the side of the recycling tank, and the agitator rods fixedly connected to the output shaft of the motor.

[0007] Preferably, a rotating shaft is rotatably installed inside the filter cavity of the recycling bin, and two discs are eccentrically fixed on the outer surface of the rotating shaft. The outer surface of the discs is in contact with the outer surface of the filter screen, and the rotating shaft is connected to the stirring rod through a transmission mechanism.

[0008] Preferably, the transmission mechanism includes synchronous pulleys fixedly mounted on the outer surfaces of the rotating shaft and multiple stirring rods, and the multiple synchronous pulleys are connected by a synchronous belt drive.

[0009] Preferably, the sides of the plurality of filters are fitted with the same slider, which is slidably mounted in a groove opened in the inner wall of the recycling bin.

[0010] Preferably, both the slider and the groove are trapezoidal, and the filter screen is slidably and detachably mounted on the slider.

[0011] Preferably, a spray plate is fixed to the upper surface of the inner wall of the recycling bin, a guide plate is fixed inside the recycling bin, and a baffle plate is used in conjunction with the guide plate.

[0012] Preferably, the mesh size of the plurality of filters decreases sequentially from top to bottom.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting up a partition plate, a filter screen, a heat dissipation coil, and a stirring mechanism, the inside of the recycling box is divided into a filtration cavity and a cooling cavity by the partition plate.

In this utility model, by setting a synchronous pulley and a synchronous belt, the stirring rod can drive the other stirring rods and rotating shaft to rotate synchronously through the synchronous belt and synchronous pulley while the stirring rod rotates, so that the filtration and stirring work are carried out simultaneously, improving the convenience of operation, while reducing the use of motor equipment and saving costs.

[0016] 3. In this utility model, by setting up a spray plate, a guide plate and a baffle, the water flow sprayed by the spray plate can better adsorb impurities in the flue gas, and at the same time can play a preliminary role in cooling the flue gas. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a continuous carbonization flue gas cooling and recovery device, comprising a recovery box 1, an air inlet pipe 2 on the recovery box 1, a partition plate 3 inside the recovery box 1 dividing the interior of the recovery box 1 into a filter cavity and a cooling cavity, a plurality of filter screens 4 in the filter cavity of the recovery box 1, and a heat dissipation coil 6 installed in the cooling cavity of the recovery box 1, with both ends of the heat dissipation coil 6 fixedly installed on the partition plate 3 and the recovery box 1 respectively, an agitation mechanism for stirring cold water in the cooling cavity of the recovery box 1, and a water inlet pipe 7 on the cooling cavity of the recovery box 1. Drainage pipes 8 are installed in both the cooling cavity and the filter cavity. By setting up a partition plate 3, a filter screen 4, a heat dissipation coil 6, and a stirring mechanism, the inside of the recovery box 1 is divided into a filter cavity and a cooling cavity by the partition plate 3. The filter screen 4 inside the filter cavity filters the flue gas, preventing impurities from entering the cavity and causing environmental harm. By injecting cold water into the cooling cavity, the cold water exchanges heat with the hot air inside the heat dissipation coil 6 to cool the flue gas. At the same time, the cold water absorbs heat for heating, which can be used for heat transfer and heat recovery, effectively reducing resource waste.

[0025] Reference Figure 4The stirring mechanism includes multiple stirring rods 9 fixedly installed in the cooling cavity of the recovery tank 1. Multiple stirring blades 10 are fixed on the outer surface of the stirring rods 9. A motor 11 is fixed on the side of the recovery tank 1. The stirring rods 9 are fixedly connected to the output shaft of the motor 11. By setting up the motor 11, stirring rods 9 and stirring blades 10, the motor 11 drives the stirring rods 9 to rotate. At the same time, the stirring rods 9 drive the stirring blades 10 to rotate synchronously, which can stir and agitate the cold water in the cooling cavity so that the cold water can come into more complete contact with the heat dissipation coil 6, avoiding the problem of uneven contact of cold water and waste.

[0026] Reference Figure 4 A rotating shaft 12 is rotatably installed inside the filter cavity of the recycling box 1. Two discs 13 are eccentrically fixed on the outer surface of the rotating shaft 12. The outer surface of the discs 13 is in contact with the outer surface of the filter screen 4. The rotating shaft 12 is connected to the stirring rod 9 through a transmission mechanism. By setting the rotating shaft 12 and the discs 13, the rotation of the rotating shaft 12 drives the discs 13 to rotate eccentrically. The rotation of the discs 13 pushes the filter screen 4 to move up and down, realizing the up and down vibration filtration of the filter screen 4 and improving the filtration effect.

[0027] Reference Figure 4 The transmission mechanism includes synchronous pulleys 14 fixedly installed on the outer surfaces of the rotating shaft 12 and multiple stirring rods 9. The multiple synchronous pulleys 14 are connected by a synchronous belt 15. By setting the synchronous pulleys 14 and the synchronous belt 15, the stirring rods 9 can drive the other stirring rods 9 and the rotating shaft 12 to rotate synchronously through the synchronous belt 15 and the synchronous pulleys 14 while the stirring rods 9 are rotating, so that the filtration and stirring work are carried out simultaneously, improving the convenience of operation, while reducing the use of the motor 11 equipment and saving costs.

[0028] Reference Figure 2 and Figure 3 Multiple filter screens 4 are equipped with the same slider 5 on their sides. The slider 5 is slidably installed in the groove opened in the inner wall of the recycling bin 1. By setting the slider 5, the slider 5 plays a guiding and limiting role for the filter screens 4, avoiding deviation and shaking during the movement of the filter screens 4, and improving stability.

[0029] Reference Figure 2 and Figure 3 Both the slider 5 and the groove are trapezoidal. The filter screen 4 is slidably and detachably installed on the slider 5. By setting the slider 5 to a trapezoidal shape, the slider 5 is prevented from detaching during use. The filter screen 4 is slidably installed on the slider 5, which can be quickly disassembled and installed, making it easier to disassemble and clean the filter screen 4 and improving the convenience of use.

[0030] Reference Figure 2 and Figure 3A spray plate 18 is fixed on the upper surface of the inner wall of the recycling bin 1. A guide plate 16 and a baffle 17 are fixed inside the recycling bin 1. By setting up the spray plate 18, the guide plate 16 and the baffle 17, the spray plate 18 sprays water to better adsorb impurities in the flue gas and at the same time play a preliminary role in cooling the flue gas.

[0031] Reference Figure 2 and Figure 3 The mesh size of the multiple filters 4 decreases from top to bottom to achieve multi-layer filtration of flue gas, improve the filtration effect, and the sequential filtration effectively avoids large impurities clogging the small mesh.

[0032] Working principle: Flue gas is sent into the recovery box 1 through the inlet pipe 2. Cold water is injected into the spray pipe, and the spray pipe sprays liquid to adsorb impurities in the gas. After being filtered by the filter screen 4, the gas enters the heat dissipation coil 6 through the guide plate 16 and the baffle 17. Cold water is injected into the cooling cavity through the water inlet pipe 7. At the same time, the motor 11 is turned on, and the motor 11 drives the stirring rod 9 to rotate. The rotation of the stirring rod 9 drives the stirring blade 10 to rotate synchronously, which can stir and agitate the cold water in the cooling cavity so that the cold water can come into more complete contact with the heat dissipation coil 6. The filtered and cooled flue gas is discharged through the heat dissipation coil 6, and the heated water is sent to other work areas that require heat supply.
