Description

Technical Field

[0001] The utility model relates to the technical field of production equipment, in particular to a steam recovery device at the bottom of a secondary combustion chamber of a hazardous waste incineration system. Background Art

[0002] The steam recovery device at the bottom of the secondary combustion chamber plays an important role in energy conservation and emission reduction, improving energy utilization and reducing emissions in the hazardous waste incineration system.

[0003] Although current technology has many advantages, its disadvantage is that, because the interior of the furnace is in a negative pressure state, when the slag remover at the bottom of the furnace is short of water, the furnace will be connected to the outside air through the slag remover, allowing the outside air to enter the furnace. This will not only affect the temperature inside the furnace, but also increase the amount of oxygen inside the furnace. In the hazardous waste incineration system, various pollution indicators will exceed the national regulations and pollute the environment. At the same time, because incineration will generate a lot of dust, this dust will pass through the furnace at an extremely high speed and reach the tail of the furnace. The dust will scratch the economizer, condensate heater and high and low pressure heaters in the tail flue, reducing the service life of the ancillary equipment. Utility Model Content

In the hazardous waste incineration system, various pollution indicators will exceed the national prescribed range, polluting the environment. At the same time, because a large amount of dust will be generated by incineration, the dust will also pass through the furnace body at an extremely high speed and reach the tail of the furnace body. In this way, the dust will scratch the economizer, condensate heater and high and low pressure heaters of the tail flue, reducing the service life of the auxiliary equipment.

The two motors 10 are provided with rotating shafts 11 through output shafts, and the outer surfaces of the two rotating shafts 11 are fixedly installed with rotating rings 12, so that the slag can first fall onto the high-level baffle 5, and then the high-level baffle 5 is opened to make the slag fall onto the low-level baffle 5. Subsequently, after the high-level baffle 5 is closed, the low-level baffle 5 is opened to make the slag fall into the bottom slag remover, thereby avoiding the influence of the slag remover air intake on the working condition of the incinerator, and laying the foundation for the stable operation of the system.

[0024] like Figure 1-4 As shown, a plurality of spoilers 15 are fixedly connected to the inner wall of the furnace body 1, and a plurality of filter plates 16 are fixedly connected to the inner wall of the furnace body 1 on the side opposite to the plurality of spoilers 15, so that dust in the flue gas inside the incinerator can be filtered, thereby avoiding the influence of dust on the tail flue equipment and improving the service life of the equipment.

[0025] like Figure 1-4 As shown, working rods 13 are fixedly connected to the outer surfaces of the two rotating rings 12, and a plurality of ash hoppers 14 are fixedly connected to the outer surface of the furnace body 1. The ash hoppers can temporarily store fly ash and process it uniformly.

[0026] like Figure 1-4 As shown, a plurality of rotating blocks 4 are evenly divided into two groups, and the two groups of rotating blocks 4 are fixedly mounted on the outer surfaces of two rotating shafts 3. The rotating blocks 4 can transmit power to the rotating shaft 3 to make the rotating shaft 3 rotate.

[0027] like Figure 1-4As shown, multiple filter plates 16 are evenly divided into six groups, and two conductive blocks 17 are fixedly connected to the outer surfaces of the six groups of filter plates 16. The conductive blocks 17 can transmit vibration to the filter plates 16, shake the dust on the filter plates 16 off, and make the dust fall into the ash hopper 14.

[0028] like Figure 1-4 As shown, the outer surfaces of the multiple conduction blocks 17 are fixedly connected with conduction rods 18, and the outer surfaces of the multiple conduction rods 18 are fixedly connected with vibration generators 19.

[0030] like Figure 1-4 As shown, a plurality of support plates 20 are fixedly connected to the outer surface of the furnace body 1 , and a plurality of conduction blocks 17 are fixedly embedded in the inner surface of the furnace body 1 . The support plates 20 can support the vibration generator 19 to improve the service life of the vibration generator 19 .

[0031] Working principle: This equipment is a steam recovery device at the bottom of the second combustion chamber of a hazardous waste incineration system. When the burned slag enters the furnace body 1 from the rotary furnace through the slag inlet 2, it will first fall onto the higher baffle plate 5, and the power supply of the motor 10 on the two support plates 9 will be turned on. The model of the motor 10 is: YE3-4KW-4, power: 4KW. The two motors 10 drive the two rotating shafts 11 to rotate clockwise through the output shaft, and the two rotating shafts 11 drive the two working rods 13 to rotate clockwise through the two rotating rings 12. When the two working rods 13 move to the top of the rotating shaft 11, the two working rods 13 will drive the two high-position baffles 8 to rotate clockwise, and the two high-position baffles 8 will rotate clockwise through the two high-position rotating blocks 4. When the two working rods 13 continue to rotate 90 degrees clockwise, the two working rods 13 will drive the two low-position baffles 8 to rotate, so that the two low-position baffles 8 can be closed. The two low-position rotating blocks 4 drive the two low-position rotating shafts 3 to rotate, and the low-position rotating shaft 3 drives the low-position baffle 5 to rotate to open the low-position baffle 5. When the two working rods 13 continue to rotate 90 degrees clockwise, the two working rods 13 no longer limit the two low-position baffles 8, and the two low-position counterweights 7 drive the two low-position rotating blocks 4 to rotate in the opposite direction through the two low-position swing rods 6, so that the two low-position rotating blocks 4 drive the low-position baffle 5 to rotate in the opposite direction through the low-position rotating shaft 3 to close the low-position baffle 5, so that the slag can first fall onto the high-position baffle 5, and then the high-position baffle 5 is opened to make the slag fall onto the low-position baffle 5, and then after the high-position baffle 5 is closed, the low-position baffle 5 is opened to make the slag fall into the bottom slag remover. The effect of air intake of the slag remover on the working condition of the incinerator is avoided, laying the foundation for the stable operation of the system. Then, the vibration generators 19 on the multiple support plates 20 are started. The multiple vibration generators 19 will vibrate through the multiple conduction blocks 17 and the multiple conduction rods 18 to drive the multiple filter plates 16 to vibrate. The spoiler 15 can disturb the gas inside the incinerator and constantly change the direction of the dust so that the dust can be better filtered by the multiple filter plates 16. The vibrating filter plates 16 will shake the dust down and make the dust fall into the ash hopper 14 for unified treatment. In this way, the dust in the flue gas inside the incinerator can be filtered, avoiding the influence of dust on the tail flue equipment and improving the service life of the equipment.
