Technical Field

[0001] The utility model relates to the technical field of cement production equipment, in particular to a bypass ventilation system for a cement kiln coordinated hazardous waste disposal production line. Background Art

[0002] In the pre-decomposition kiln system of the cement kiln, the raw fuel composition has a greater impact on the system. The use of raw materials and fuels with high chlorine, sulfur and alkali content will make the system more prone to faults such as crusting and blockage. The most prone to crusting and blockage are the smoke chamber at the end of the kiln, the discharge slope, the necking and the cone of the lowest cyclone, the discharge pipe of the lowest two cyclones, etc. Since the chlorine content in hazardous waste is higher than the control requirement of cement production, it may cause crusting and blockage in the pre-decomposition system. Therefore, additional vents are installed on the rising flue at the end of the kiln of the cement clinker production line to reduce the circulation and enrichment of harmful gases.

[0021] Example: Figure 1-6As shown, the utility model provides a bypass venting system for a cement kiln coordinated disposal of hazardous waste production line, including a quenching device, a cyclone dust collector, a multi-tube cooler, a bag dust collector, a kiln tail chimney, an ash bin and a clinker storage, the bag dust collector includes a box body 1, an air inlet pipe 11 is fixedly installed on one side of the box body 1, an exhaust pipe 12 is fixedly installed on the top of the box body 1, a discharge pipe 13 is fixedly installed on the bottom of the box body 1, and the air inlet pipe 11, the exhaust pipe 12 and the discharge pipe 13 are connected to the inside of the box body 1, a guide plate 14 is fixedly installed in the box body 1, and a mounting plate 5 is slidably installed in the box body 1.

The hot air is mixed with the cold air entering in a vortex manner, and the extracted 5-10% of the hot gas at about 1100°C can be quenched to 300°C or even lower, which is conducive to the next step of processing. The gas coming out of the quenching device is collected by the cyclone dust collector, and the part of the gas wrapped with fine materials enters the high-efficiency multi-tube cooler again, so that the temperature is reduced from 300°C to 120-150°C. The cooled gas passes through the bag dust collector. The collected dust is sent to the ash bin together with the dust collected by the multi-tube cooler, and finally the collected kiln ash is sent to the clinker warehouse to be used as cement mixed material. The clean air at the dust collector fan outlet is led to the chimney at the end of the kiln through the air duct for discharge. When the bag dust collector needs to be cleaned, the gas tank 3 is opened to allow the high-pressure gas in the tank to be sprayed out through the nozzle 4 and the nozzle 41. At the same time, the vibration component 2 is used to drive the mounting plate 5 and the bag 6 to shake up and down in the box body 1, so as to clean up the dust adsorbed on the bag 6 and discharge it through the discharge pipe 13. The locking component 7 can be used to quickly install and disassemble the bag 6.

[0022] The vibration assembly 2 includes two turntables 26 that are distributed in a mirror image, and the turntables 26 are rotatably installed in the box body 1. A connecting plate 27 is hingedly installed on the two turntables 26, and the bottom end of the connecting plate 27 is hingedly connected to the mounting plate 5.

[0023] By adopting the above technical solution, the rotating disk 26 drives the mounting plate 5 to swing up and down in the box body 1 through the connecting plate 27 .

[0024] A second worm gear 25 is fixedly mounted on one end of each of the two rotating disks 26 , and a first worm 24 is rotatably mounted on both sides of the housing 1 , and the first worm 24 is meshed with the corresponding second worm gear 25 .

[0025] By adopting the above technical solution, the first worm 24 drives the second worm gear 25 to rotate, and the second worm gear 25 drives the rotating disk 26 to rotate.

[0026] The first worm wheel 22 is fixedly mounted on one end of the two first worms 24 , and a double-headed worm 23 is rotatably mounted on one side of the housing 1 , and the double-headed worm 23 is meshed with the first worm wheel 22 .

[0027] By adopting the above technical solution, the double-headed worm 23 drives the first worm wheel 22 to rotate, and the first worm wheel 22 drives the first worm 24 to rotate.

[0028] A driving motor 21 is fixedly mounted on one side of the housing 1 , and an output end of the driving motor 21 is fixedly connected to one end of a double-headed worm 23 .

[0029] By adopting the above technical solution, the driving motor 21 is started to drive the double-headed worm 23 to rotate.

[0030] Multiple locking components 7 all include two symmetrically distributed limiting rings 71, and the limiting rings 71 are fixedly mounted on the corresponding fixing rings 61. The upper surface of the mounting plate 5 is slidably provided with multiple evenly distributed spring blocks 72, and the spring blocks 72 are slidably inserted into the corresponding limiting rings 71.

[0031] By adopting the above technical solution, the spring block 72 is slid to disengage the spring block 72 from the limiting ring 71 on the fixing ring 61 , and then the cloth bag 6 is removed from the mounting plate 5 .

[0032] Working principle: When the bypass venting system needs to be turned on, the high-temperature exhaust gas in the upper part of the kiln tail smoke chamber is extracted from the bypass venting port, and a quenching device is set at the gas intake point. The hot air is mixed with the cold air entering in a vortex manner, and the extracted 5-10% of the hot gas at about 1100°C can be quenched to 300°C or even lower, which is convenient for the next step of processing. The gas coming out of the quenching device is collected by the cyclone dust collector, and the part of the gas wrapped with fine materials enters the high-efficiency multi-tube cooler again, so that the temperature is reduced from 300°C to 120-150°C. The cooled gas passes through the bag dust collector, and the collected dust is sent to the ash bin together with the dust collected by the multi-tube cooler. Finally, the collected kiln ash is sent to the clinker warehouse as cement mixing material, and the clean air at the dust collector fan outlet is led to the chimney at the kiln tail through the air duct for discharge;

[0033] When it is necessary to clean the bag dust collector, open the gas tank 3 so that the high-pressure gas in the tank is sprayed out through the nozzle 4 and the nozzle 41, and at the same time start the driving motor 21 to drive the double-headed worm 23 to rotate, the double-headed worm 23 drives the first worm gear 22 to rotate, the first worm gear 22 drives the first worm 24 to rotate, the first worm gear 24 drives the second worm gear 25 to rotate, and the second worm gear 25 drives the turntable 26 to rotate. The turntable 26 drives the mounting plate 5 and the cloth bag 6 to shake up and down quickly in the box body 1 through the connecting plate 27, so that the dust adsorbed on the cloth bag 6 is cleaned and discharged through the discharge pipe 13. When it is necessary to disassemble and replace the cloth bag 6, slide the spring block 72 to disengage the spring block 72 from the limit ring 71 on the fixing ring 61, and then remove the cloth bag 6 from the mounting plate 5, thereby achieving the purpose of quickly installing and disassembling the cloth bag 6 using the locking assembly 7.
