Description

Technical Field

[0001] The utility model relates to the technical field of coke dry quenching, and particularly relates to a heat recovery storage tank for coke dry quenching waste heat power generation. Background Art

[0002] Coke dry quenching, that is, dry coke quenching, is a coke quenching method relative to wet coke quenching. Coke dry quenching uses an inert gas (usually nitrogen) to counter-currently exchange heat with red-hot coke in a dry quenching furnace, so as to cool the coke. High-temperature coke is charged from the top of the dry quenching furnace, and the inert gas is blown into the bottom of the dry quenching furnace. After absorbing the heat of the coke, the temperature rises. The hot inert gas is discharged from the top of the dry quenching furnace and enters a waste heat boiler for heat exchange to generate steam for power generation or other uses. The heat energy carried by these high-temperature inert gases is introduced into a heat recovery storage tank, and the storage tank usually uses special heat-insulating materials to reduce heat loss. When power generation is required, the high-temperature heat energy in the storage tank is released to heat water to generate steam and drive a steam turbine to generate electricity.

[0003] When the currently used storage tank recovers high-temperature inert gas, the high-temperature gas will be transported to the inside of the storage tank. Since the space inside the storage tank is relatively large, the activity space of the high-temperature gas inside the storage tank will be relatively large, which easily leads to heat loss of the high-temperature gas. After the high-temperature gas is stored in the storage tank for a period of time, the temperature will quickly drop, affecting subsequent use. Summary of the Utility Model

[0029] Embodiment

[0030] Refer to Figures 1 - 5, the present utility model provides a technical solution: a heat recovery storage tank for dry quenching coke waste heat power generation, including a treatment tank 1 and a storage mechanism 3, and a collection tank 2 is further arranged outside the treatment tank 1. The storage mechanism 3 includes an annular plate 31, the annular plate 31 is fixedly installed inside the collection tank 2, and a movable circular plate 311 is arranged on the annular plate 31. A hollow tube 32 is installed on the upper surface of the circular plate 311, and the bottom end of the hollow tube 32 penetrates through the bottom of the circular plate 311. An intake air bag 321 is stably installed at the top of the hollow tube 32. An intake pipe 33 is fixedly installed outside the collection tank 2, and the treatment tank 1 and the collection tank 2 are communicated through the intake pipe 33.

[0031] In a preferred embodiment, an annular cylinder 4 is fixedly installed inside the treatment tank 1, and a feeding bin 5 is fixedly installed at the top of the treatment tank 1. One end of the feeding bin 5 is arranged inside the annular cylinder 4. At the same time, a slag discharge pipe 6 is fixedly installed at the bottom of the treatment tank 1. Partition bars 7 are fixedly installed inside the annular cylinder 4. To facilitate feeding of this device, a feeding bin 5 is installed at the top of the treatment tank 1. At the same time, an annular cylinder 4 is arranged inside the treatment tank 1. The raw material is heated inside the annular cylinder 4 to heat the gas outside the annular cylinder 4, so as to heat the gas into a high-temperature gas to meet the use.

[0032] In a preferred embodiment, a first temperature sensor 8 is fixedly installed on the outer surface of the treatment tank 1, and an electronic control valve 9 is fixedly installed on the outside of the intake pipe 33. The first temperature sensor 8 is electrically connected to a PLC controller 10, and the PLC controller 10 is electrically connected to the electronic control valve 9. To prevent the gas from being in a normal temperature state inside the treatment tank 1, an electronic control valve 9 is arranged on the intake pipe 33, and a first temperature sensor 8 is installed on the treatment tank 1. The temperature of the gas inside the treatment tank 1 is detected by the first temperature sensor 8. When the temperature reaches the set value, the electronic control valve 9 can be controlled to open through the PLC controller 10, and the high-temperature gas can be transported into the collection tank 2.

[0033] In a preferred embodiment, a second temperature sensor 12 is stably installed outside the collection tank 2, and a pressure sensor 13 is also installed outside the collection tank 2. An exhaust pipe 14 is fixedly installed on the outer surface of the collection tank 2. This device stores the high-temperature gas inside the collection tank 2. To ensure safety, a second temperature sensor 12 and a pressure sensor 13 are stably installed outside the collection tank 2. The air pressure and temperature inside the collection tank 2 are detected through the cooperation of the two. And a plurality of second temperature sensors 12 are arranged to detect the temperature of each area to improve safety.

[0034] In order to prevent the temperature loss of high-temperature gas, the device is provided with a plurality of annular plates 31, which are evenly arranged inside the collecting tank 2, and a circular plate 311 is provided on each annular plate 31. A hollow tube 32 is also installed on the circular plate 311. The interior of the collecting tank 2 is divided into a plurality of areas by the circular plate 311. By collecting the gas, the gas is collected at different positions inside the collecting tank 2 according to different air pressures, so as to meet the use requirements.

[0035] The gas is heated and will contain moisture. In order to remove moisture from the gas, a dewatering mechanism 15 is installed inside the collection tank 2. The dewatering mechanism 15 includes a heat insulation plate 151 and a mesh plate 152. The heat insulation plate 151 is fixedly installed on the inner wall of the collection tank 2 and surrounds the annular plate 31 to keep the gas warm. The mesh plate 152 is fixedly installed on the heat insulation plate 151, and a lime bag is arranged on the inner side of the mesh plate 152, and a plurality of small holes are arranged on the outer surface of the lime bag. An empty warehouse plate 11 is fixedly installed at the bottom end of the interior of the collection tank 2, and a lime bag is also arranged inside the empty warehouse plate 11.

[0036] In actual use, high-temperature gas is introduced into the collection tank 2 through the air inlet pipe 33, and the gas is input from the bottom of the collection tank 2. As the high-temperature gas continues to rise, it will move to the position of the empty warehouse plate 11. Since small holes are set on the outer surface of the lime bag, the lime is block-shaped, and the high-temperature gas contains a certain amount of moisture. When the gas contacts the lime, the moisture in the gas will be absorbed by the lime to remove the moisture in the gas.

[0037] Specifically, the working process or working principle of a heat recovery storage tank for CDQ waste heat power generation is as follows: when the currently used storage tank recovers high-temperature inert gas, the high-temperature gas will be transported to the inside of the storage tank. Since the space inside the storage tank is large, the activity space of the high-temperature gas inside the storage tank will be relatively large, which will easily lead to heat loss of the high-temperature gas. As a result, after the high-temperature gas is stored in the storage tank for a period of time, the temperature will drop quickly, affecting subsequent use. Therefore, this device is designed to solve this problem.

[0038] The device can collect and store gas, and set up separate storage, which can reduce the storage space and reduce the temperature loss rate of the gas for later use. The specific operation is that high-temperature coke is loaded from the top of the processing tank 1, and the inert gas is blown in from the bottom of the processing tank 1 and absorbs the heat of the coke to increase the temperature. The hot inert gas is discharged from the top of the processing tank 1, and the cooled coke is discharged from the bottom of the processing tank 1. The high-temperature gas will be introduced into the collection tank 2 so that the high-temperature gas is stored in the collection tank 2. The high-temperature gas is introduced into the collection tank 2 through the air inlet pipe 33. The gas will be input from the bottom of the collection tank 2. As the high-temperature gas continues to rise, it will move to the position of the empty warehouse plate 11. Since small holes are set on the outer surface of the lime bag, the lime is block-shaped, and the high-temperature gas contains a certain amount of moisture. When the gas contacts the lime, the moisture in the gas will be absorbed by the lime to remove the moisture in the gas.

[0039] As the amount of gas at the bottom end of the collecting tank 2 increases, the air pressure at this position continues to increase. When the gas pressure can push the circular plate 311 upward, the circular plate 311 will be separated from the annular plate 31, and a gap will be formed between the two. At this time, the gas at the bottom end of the collecting tank 2 will rise from the gap, and the gas will also enter the hollow tube 32 and expand the air inlet bag 321. When the air inlet bag 321 expands, it will push the upper circular plate 311 to move, and according to the above method, continue to control the gas to rise, so that the gas is collected inside the collecting tank 2 and a certain temperature can be maintained inside the collecting tank 2.

[0040] This device gradually raises the gas. When the gas pressure is small, it will only stay in one area blocked by the circular plate 311, making the space much smaller than the overall space inside the collection tank 2, reducing the fluidity of the gas, thereby avoiding rapid temperature loss of the gas. When the gas pressure increases, the storage space will be expanded, thereby ensuring that the high-temperature gas can be stored at a certain temperature for a long time.

[0041] When the stored gas needs to be used, the external pipeline is connected to the exhaust pipe 14, so that all the gas inside the collection tank 2 can be extracted for use. When the air pressure inside the collection tank 2 decreases, the circular plate 311 will fall onto the annular plate 31, and the air inlet bag 321 will also become deflated for later use.
