Description

Technical Field

[0001] This utility model relates to the field of coke oven gas spray slag removal technology, specifically a coke oven gas spray slag removal nozzle that is easy to maintain. Background Technology

[0002] In the current low-temperature dry distillation process, coke oven gas contains a certain amount of dust. By setting multiple spray devices on the bridge pipe to generate droplets that combine with the dust and settle down, the dust in the gas is removed and flows into ammonia water, thereby purifying the gas. However, the atomizing nozzles will be blocked by the solidification and condensation of tar in the circulating spray water during long-term use, affecting the atomization effect. The common solution is to use iron wire to unclog them, but this cannot completely solve the problem. At the same time, if the atomizing nozzle is damaged, it cannot be replaced in time and can only be replaced when the oven is shut down. Utility Model Content

[0023] 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.

[0024] Please see Figures 1 to 3 This utility model provides a technical solution: a coke oven gas spray slag removal nozzle that is easy to maintain, comprising: a second water inlet pipe 2; an outer support plate 13 fixedly connected to the outside of the second water inlet pipe 2, a rotary joint 3 installed on the top of the outer support plate 13, and the top of the second water inlet pipe 2 connected to the rotary joint 3; an internal threaded cylinder 14 fixedly connected to the bottom of the outer support plate 13, and the internal threaded cylinder 14 fixedly connected to the second water inlet pipe 2; a top perforated blind plate 4 placed on the outside of the second water inlet pipe 2, and the inside of the top perforated blind plate 4 having a through hole 18 that mates with the second water inlet pipe 2; an external threaded sleeve 15 fixedly connected to the top of the top perforated blind plate 4, and the external threaded sleeve 15 located on the outside of the second water inlet pipe 2; a first water inlet pipe 1 installed on the top of the rotary joint 3; a top mating flange 5 installed on the bottom of the top perforated blind plate 4 by bolts, and an intermediate pipe 6 fixedly connected to the bottom of the top mating flange 5; and a knife gate valve 8 placed below the intermediate pipe 6.

[0025] It should be noted that in this embodiment, an atomizing nozzle 12 is installed at one end of the No. 2 water inlet pipe 2. Under high pressure, the water is atomized into small droplets by the nozzle, which combine with solid particles in the gas and settle, achieving the purpose of spraying to reduce dust and purify the gas. During installation, the internal threaded cylinder 14 at the bottom of the outer support plate 13 is above the external threaded sleeve 15. The hexagonal external fixing sleeve 16 rotates the outer support plate 13 and the internal threaded cylinder 14. The inner thread of the internal threaded cylinder 14 engages with the outer thread of the external threaded sleeve 15, installing the internal threaded cylinder 14 and the outer support plate 13 on the external threaded sleeve 15. The internal threaded cylinder 14 is limited by the sealing sleeve 19 and the external fixing ring 20. The sealing ring 21 enters the annular sealing groove 17 to ensure the sealing effect and prevent gas leakage. The through hole 18 in the top perforated blind plate 4 is 1.5mm larger than the diameter of the No. 2 water inlet pipe 2, so that no large amount of gas will leak out when it is detached. The top perforated blind plate 4 and the top mating flange 5 adopt... The top mating flange 5, intermediate pipe 6, and upper knife gate valve mating flange 7 are connected by bolts and welded together. The knife gate valve 8, upper knife gate valve mating flange 7, and lower knife gate valve mating flange 9 are connected by bolts. The lower knife gate valve mating flange 9 is welded to the lower connecting pipe 10, and the lower connecting pipe 10 is welded to the gas bridge pipe 11. When it is necessary to replace the atomizing nozzle 12, the outer support plate 13 and the internal threaded cylinder 14 are rotated through the hexagonal outer fixing sleeve 16. Disconnect the internal threaded cylinder 14 from the external threaded sleeve 15. The outer support plate 13, internal threaded cylinder 14, second water inlet pipe 2, rotary joint 3, and first water inlet pipe 1 are moved upward as a whole. The atomizing nozzle 12 is driven to the intermediate pipe 6 through the second water inlet pipe 2. At this time, the knife gate valve 8 is closed. Then, the top perforated blind plate 4 is removed from the top mating flange 5. The first water inlet pipe 1 and the atomizing nozzle 12 are taken out as a whole. The atomizing nozzle 12 can then be inspected and replaced.

[0026] In one embodiment, such as Figures 1 to 3 As shown, a sealing ring 21 is fixedly connected to the top of the external threaded sleeve 15, and an annular sealing groove 17 that mates with the sealing ring 21 is opened inside the internal threaded cylinder 14.

[0027] It should be noted that, in this embodiment, the sealing ring 21 at the top of the external threaded sleeve 15 cooperates with the annular sealing groove 17 inside the internal threaded cylinder 14 to complete the sealing between the external threaded sleeve 15 and the internal threaded cylinder 14. Combined with the threaded connection between the internal threaded cylinder 14 and the outer side of the external threaded sleeve 15, the sealing effect is further guaranteed.

[0028] In one embodiment, such as Figures 1 to 3 As shown, an outer fixing ring 20 is fixedly connected to the outer side of the external threaded sleeve 15, and a closed sleeve 19 that mates with the internal threaded cylinder 14 is fixedly connected to the top of the outer fixing ring 20.

[0029] It should be noted that in this embodiment, the outer fixing ring 20 is fixed on the outside of the outer threaded sleeve 15, and the closing sleeve 19 is fixed on the top of the outer fixing ring 20, thereby restricting the installation position of the inner threaded sleeve 14 on the outside of the outer threaded sleeve 15.

[0030] In one embodiment, such as Figures 1 to 3 As shown, an atomizing nozzle 12 is installed at the bottom of the second water inlet pipe 2, and a hexagonal outer fixing sleeve 16 is fixed to the outside of the outer support plate 13.

[0031] It should be noted that in this embodiment, the water in the No. 2 water inlet pipe 2 is sprayed out through the atomizing nozzle 12. Under high pressure, the water is atomized into small droplets by the nozzle, which combine with the solid particles in the coal gas and settle down, thereby achieving the purpose of spraying to reduce dust and purify the coal gas.

[0032] In one embodiment, such as Figure 1 As shown, the bottom of the intermediate pipe 6 is fixedly connected to the upper knife gate valve mating flange 7, the bottom of the upper knife gate valve mating flange 7 is bolted to the knife gate valve 8, the bottom of the knife gate valve 8 is bolted to the lower knife gate valve mating flange 9, and the bottom of the lower knife gate valve mating flange 9 is fixedly connected to the lower connecting pipe 10.

[0033] It should be noted that in this embodiment, when the atomizing nozzle 12 reaches the middle tube 6, the knife gate valve 8 is closed for sealing.

[0034] In one embodiment, such as Figure 1 As shown, a gas bridge pipe 11 is fixedly connected to the bottom end of the lower connecting pipe 10.

[0035] It should be noted that in this embodiment, the lower connecting pipe 10 is fixed at the top of the gas bridge pipe 11.
