Description

Technical Field

[0001] This utility model relates to the technical field of spray purification devices, specifically to a spray purification device for a coke oven gas primary cooler. Background Technology

[0002] High naphthalene content in coke oven gas is a challenging problem. It not only condenses into flaky crystals in gas pipelines, causing blockages, but also affects the efficiency of hydrogen sulfide removal, thus impacting the operation of the entire gas purification system. In winter, naphthalene in coke oven gas easily condenses into a solid when the temperature drops, especially in the 30-40°C range. When the naphthalene content reaches 900-2100 mg / m³, it is more likely to deposit on the surfaces of pipelines and equipment, and it also affects the conversion performance of hydrogenation catalysts, impairing their conversion efficiency. Existing coke oven gas primary cooler spray purification devices use spray heads to evenly spray tar, allowing the spray liquid to fully contact and clean the naphthalene and tar in the gas. Although the above method can achieve the cleaning effect of the device on naphthalene in the gas, when cleaning, the content of impurities in the gas varies. When using the same concentration of cleaning liquid for spraying, it is easy to have incomplete cleaning or waste of cleaning liquid, resulting in poor gas purification effect of the device.

The design of the first pipe 10 and the second pipe 15 facilitates the connection to an external liquid supply device, enabling the first pipe 10 and the second pipe 15 to supply liquid to the first spray head 14 and the second spray head 11 respectively. During the spray washing of naphthalene, the concentration of the cleaning liquid in the two connecting pipes 10 and the second pipe 15 can be adjusted according to the naphthalene content in the gas, realizing the separate adjustment of the concentration of the spray liquid at the upper and lower ends. The concentration of the spray solution can be flexibly adjusted according to the content of impurities in the gas and the requirements of the spraying effect, effectively ensuring the cleaning effect of the device on the gas. A gas supply pipe 19 is set on one side wall of the spray box 1 at the bottom of the second pipe 15. A guide plate 12 is arranged at the bottom of the spray box 1. A water outlet pipe 16 is installed at the bottom of one side wall of the spray box 1. A one-way solenoid valve 17 is connected in the water outlet pipe 16.

A coarse filter plate 21 is arranged between the limiting blocks 23 at one end. A fine filter plate 18 is installed between the limiting blocks 23 in the middle. An adsorption plate 20 is arranged between the limiting blocks 23 at the other end.

[0017] like Figures 1-3 As shown, in this embodiment, the gas supply pipe 19 is flange-connected to both the spray box 1 and the filter box 3, the air inlet pipe 24 is flange-connected to the filter box 3, and the ash collection hopper 22 is slidably connected to the filter box 3.

[0018] like Figures 1-3As shown, in this embodiment, the limiting block 23 is screwed to the filter box 3 and the ash collection hopper 22. The coarse filter plate 21, the fine filter plate 18 and the adsorption plate 20 are slidably connected to the limiting block 23.

The design of the limiting slide rail 7 makes it convenient to pull out the horizontal plate 8 or the grid plate 13 for maintenance.

[0020] like Figures 1-3 As shown, in this embodiment, activated carbon particles 6 are connected to the horizontal plate 8 via a slot, condensation circulation pipe 9 is connected to the horizontal grid slot of the grid plate 13, and the guide plate 12 is inclined at 60 degrees. Activated carbon particles 6 can adsorb and discharge odors in the coal gas, effectively ensuring the cleanliness of the coal gas in the discharge device. Condensation circulation pipe 9 can exchange and discharge heat in the coal gas.

Combined with the adsorption plate 20 adsorbing the gas, it can effectively prevent impurities in the gas from entering the spray box 1. Then, the connecting pipe 10 and the connecting pipe 25 are connected to the liquid supply equipment respectively, realizing the delivery of spray to the connecting pipe 10 and the connecting pipe 25 respectively. During the transportation process, the concentration of the spray liquid can be adjusted sequentially according to the actual naphthalene content in the coal gas, so that the spray head 14 and spray head 11 can spray the coal gas evenly, realizing the reaction and dissolution between naphthalene in the coal gas and the spray liquid. Then, when the coal gas passes through the grid plate 13, the condensation circulation pipe 9 on the grid in the middle of the grid plate 13 will adsorb and exchange the heat in the coal gas, realizing the cooling of the coal gas by the device. Combined with the secondary adsorption of activated carbon particles 6, the purity of the discharged coal gas is effectively guaranteed. After the spray liquid flows out of the water outlet pipe 16 through the guide plate 12, it is convenient for centralized treatment.
