Abstract
Description
Technical Field
[0001] This utility model relates to the field of coke quenching car technology, specifically to a desulfurization and dust removal device for coke quenching cars. Background Technology
[0002] A coke quenching car is a special piece of equipment in the coking workshop of a steel plant. Its main function is to quench the burning coke in the coke oven so that subsequent cleaning and maintenance work can be carried out. The coke quenching car usually moves along a specific route, so it is generally designed to run like a train on railway tracks.
[0003] When the coke quenching car is transporting high-temperature red coke, the red coke is pushed out of the coke oven and falls into the coke quenching car, which will generate a large amount of flue gas. The flue gas contains dust particles and sulfur dioxide, which will cause serious pollution if it enters the environment. In order to address the above problems, this application designs a desulfurization and dust removal device for the coke quenching car. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a desulfurization and dust removal device for coke quenching cars.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a desulfurization and dust removal device for a coke quenching car, comprising a coke quenching car body, wherein a purification mechanism for desulfurization and dust removal is provided on the coke quenching car body, the purification mechanism comprising an air intake device, a smoke extraction pipe, a circulation device, and a treatment box, wherein the smoke extraction pipe is fixed at the top of the side wall of the coke quenching car body, and a smoke inlet is provided on the smoke extraction pipe, the smoke inlet being located inside the coke quenching car and facing downwards, the air intake device being installed on the side wall of the coke quenching car body directly below the smoke extraction pipe, the air intake device being connected to the smoke extraction pipe, the circulation device being installed on the coke quenching car body, and the treatment box being fixed in the circulation device. At the top of the ring device, the treatment box contacts the side wall of the coke quenching car body. The treatment box contains a desulfurization chamber and a dust removal chamber arranged sequentially from top to bottom. The circulation device is connected to the dust removal chamber. An exhaust pipe is connected to the suction device. The exhaust pipe passes through the treatment box and is located inside the dust removal chamber. Multiple containers are slidably connected inside the desulfurization chamber. Multiple leakage holes are provided at the bottom of each container. One end of each container passes through the treatment box and is fixed with an end plate. The end plate is located outside the treatment box and contacts its outer wall. A handle is fixed to the end plate. Multiple exhaust pipes are connected to the top of the treatment box. Water is provided inside the dust removal chamber, and adsorbent particles are provided inside the containers.
[0008] To ensure that the gas in the exhaust pipe comes into contact with water first when it is discharged, the present invention is improved by providing multiple downward-facing air outlets on the exhaust pipe located inside the dust removal chamber.
[0009] To prevent flue gas from leaking at the end plate, this utility model is improved by fixing an annular sealing strip on the side of the end plate that contacts the processing box.
[0010] To prevent burns, this invention is improved by providing an anti-scalding sleeve on the external portion of the exhaust pipe.
[0011] To prevent sulfides in the flue gas from causing corrosion damage to the device, this utility model is improved by providing an anti-corrosion coating on the inner wall of the treatment box.
[0012] (III) Beneficial Effects
[0013] Compared with the prior art, this utility model provides a desulfurization and dust removal device for coke quenching cars, which has the following beneficial effects:
[0014] The desulfurization and dust removal device for the coke quenching car uses a smoke extraction pipe installed above the coke quenching car body. Under the action of the suction device, the flue gas generated by the red coke to be transported is quickly absorbed and discharged into the dust removal chamber containing water through the exhaust pipe. The dust particles in the flue gas will remain in the water. After passing through the water, the flue gas floats upward and passes through multiple containers containing adsorbent particles. It floats upward through the leakage holes and comes into full contact with the adsorbent particles, removing sulfides from the flue gas and realizing the desulfurization and dust removal operation of the flue gas.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 A desulfurization and dust removal device for a coke quenching car includes a coke quenching car body 1. The coke quenching car body 1 is equipped with a purification mechanism for desulfurization and dust removal. The purification mechanism includes an air intake device 2, a smoke extraction pipe 3, a circulation device 4, and a treatment box 5. The smoke extraction pipe 3 is fixed to the top of the side wall of the coke quenching car body 1 and has a smoke inlet 6 located inside the coke quenching car and facing downwards. The air intake device 2 is installed on the side wall of the coke quenching car body 1, directly below the smoke extraction pipe 3, and is connected to the smoke extraction pipe 3. The circulation device 4 is installed on the coke quenching car body 1, and the treatment box 5 is fixed to the top of the circulation device 4. The treatment box 5 is connected to the coke quenching car body 1. The treatment box 5 has a desulfurization chamber 7 and a dust removal chamber 8 arranged sequentially from top to bottom. The circulation device 4 is connected to the dust removal chamber 8. The air intake device 2 is connected to an exhaust pipe 9. The exhaust pipe 9 passes through the treatment box 5 and is located inside the dust removal chamber 8. Multiple containers 10 are slidably connected inside the desulfurization chamber 7. Multiple leakage holes 11 are provided at the bottom of the containers 10. One end of the containers 10 passes through the treatment box 5 and is fixed with an end plate 12. The end plate 12 is located outside the treatment box 5 and contacts its outer wall. A handle 13 is fixed on the end plate 12. Multiple exhaust pipes 14 are connected to the top of the treatment box 5. Water is provided in the dust removal chamber 8. Adsorbent particles are provided in the containers 10.
[0023] When this device is in use, after the coke quenching car body 1 loads the high-temperature red coke, it carries out a large amount of flue gas containing sulfides and dust from the coke oven. The high temperature of the car itself also generates this flue gas. The suction device 2 is activated to quickly absorb the flue gas at the suction pipe 3 and transport it to the exhaust pipe 9. Simultaneously, the dust collection chamber 8 is filled with water, with the water level above the exhaust pipe 9. Under the action of the suction device 2, the flue gas is first discharged into the water at the exhaust pipe 9. Dust particles in the flue gas are absorbed upon contact with the water. At the same time, the circulation device 4 is activated to circulate the water in the dust collection chamber 8, ensuring its cleanliness and achieving the desired effect of flue gas purification. After dust removal, the flue gas continues to rise due to its physical properties. After being separated from water, it rises through the perforation 11 to fully contact the adsorbent particles. The adsorbent particles absorb the sulfides in the flue gas, and the flue gas rises and passes through multiple containers 10 containing adsorbent particles in sequence to achieve full desulfurization. The flue gas after dust removal and desulfurization rises and is discharged into the environment at the exhaust pipe. When the adsorbent particles adsorb for a long time, the effect decreases. When they need to be replaced, pull the handle 13 to pull the end plate 12 and the container 10 out of the desulfurization chamber 7 to replace the adsorbent particles. After replacement, they are reinserted into the desulfurization chamber 7.
[0024] In actual use, it was found that the quenching car body 1 needs to move constantly. During the movement, the water in the dust removal chamber 8 shakes, which sometimes causes the flue gas discharged from the exhaust pipe 9 to not come into contact with the water for dust removal, affecting the dust removal effect. In order to solve the above problem, in this embodiment, the exhaust pipe 9 is provided with multiple air outlets 15 located inside the dust removal chamber 8 and facing downwards.
[0025] In actual use, it was found that there was a gap at the contact point between the end plate 12 and the treatment box 5, and the flue gas that was not completely desulfurized would leak through the gap. In order to avoid the above problem, in this embodiment, an annular sealing strip 16 is fixed on the side of the end plate 12 that contacts the treatment box 5.
[0026] In actual use, it was found that when the red coke is loaded, the generated flue gas temperature is high. When it passes through the exhaust pipe 9, it will heat up, which can easily cause burns when replacing adsorbent particles. In order to avoid the above problems, in this embodiment, the external part of the exhaust pipe 9 is provided with an anti-scalding sleeve 17.
[0027] In actual use, it was found that sulfides in the flue gas can cause corrosion damage to the device. In order to solve the above problem, in this embodiment, the inner wall of the treatment box 5 is provided with an anti-corrosion coating.
