[0026] See Figure 1 As shown, the wet dust collector for coke transfer in this embodiment includes a wet dust removal tower 1 and a dust collection pipe fitting 2. The dust collection pipe fitting 2 is provided with a dust collection pipe 21, and a plurality of air inlets 22 are provided on the dust collection pipe 21, and an induced draft fan 23 is installed at the position of the air inlets 22. The plurality of air inlets 22 are used to be set at a plurality of coke transfer locations. The wet dust removal tower 1 includes a tower body 11, an air inlet pipe 12, a gas distribution plate 13, a spray structure 14, a gas-liquid separator 15, an electrostatic precipitator 16, and an air outlet pipe 17. The air inlet pipe 12 is arranged near the lower end of the tower body 11 and is connected to the dust collection pipe 21 and the dust removal pipe of the truck to be dusted. The gas distribution plate 13, the spray structure 14, the gas-liquid separator 15, and the electrostatic precipitator 16 are sequentially arranged at intervals from bottom to top in the tower body 11. The air outlet pipe 17 is arranged at the top of the tower body 11. A circulation water tank 18 is provided at the bottom inside the tower body 11, and the circulation water tank 18 is connected to the spray structure 14 through a circulation pipeline 19.
[0027] The structure of this embodiment is simple and reasonable in design. By setting the dust collection pipe 21 and the wet dust removal tower 1, the steam and coke dust formed during the coke transfer process can be uniformly collected into the wet dust removal tower 1. After effective dust removal, it is then discharged outside through the air outlet pipe 17, avoiding the problem of poor effect of the dust removal bag and having good dust removal effect.
[0028] The specific dust removal process of this embodiment is as follows:
[0029] Lay pipes along the top of the belt corridor. Through a plurality of air inlets 22, the steam and coke dust at the tail joint of the pipe belt machine, each transfer station, and the connected belt corridor are sucked and sent to the wet dust removal tower 1. The atomized water sprayed by the spray structure 14 contacts the dust-containing gas evenly distributed by the gas distribution plate 13 in a reverse direction. After spray dust removal and temperature reduction, the dust-containing gas enters the gas-liquid separation area. In the gas-liquid separator 15, the liquid water and particulate matter carried in the gas are separated from the gas under the action of centrifugal force and inertia. Then it enters the electrostatic precipitator 16 for further dust removal treatment. After that, the purified gas is discharged outside, or is discharged outside after being sent into the inlet of the dust removal ground station fan of the screening coke building.
[0030] In some embodiments, a dust collection hood 24 is further installed at the position of the air inlet 22.
[0031] In this embodiment, by setting the dust collection hood 24, it is convenient to suck steam and coke dust.
[0032] In some embodiments, the spraying structure 14 is provided with atomizing nozzles 141.
[0033] In this embodiment, by setting the atomizing nozzles 141, it is convenient to form atomized water vapor, so as to better contact with the dust-containing gas and achieve the dust removal effect.
[0034] In some embodiments, the electrostatic precipitator 16 is set as a honeycomb tube type wet electrostatic precipitator 16.
[0035] Specifically, the honeycomb tube type wet electrostatic precipitator 16 is connected with a flushing pipe fitting 161.
[0036] In this embodiment, it is specifically shown that the honeycomb tube type wet electrostatic precipitator 16 in the prior art is adopted. Since this type of electrostatic precipitator 16, as shown in Figure 2 described, its dust removal chamber has dust removal tubes with a honeycomb-shaped cross section arranged vertically, so that the dust removal can be evenly distributed to ensure the dust removal effect. And after the dust removal is used for a period of time, the inside of the dust removal chamber can be flushed through the flushing pipe fitting 161 to ensure efficient and comprehensive flushing and cleaning inside the dust removal chamber, thereby ensuring the stability of the dust removal effect.
[0037] In some embodiments, a sewage pipe fitting 181 is provided at the bottom end of the circulation water tank 18.
[0038] In this embodiment, since the water generated during the spraying process of the spraying structure 14 directly flows into the circulation water tank 18, after being used for a period of time, dust sludge will be generated. Through the sewage pipe fitting 181, it can be discharged and processed regularly. Its structure is simple and practical.
[0039] In some embodiments, butterfly valves 3 are respectively installed on the dust inlet pipe 12 and the air outlet pipe 17.
[0040] In this embodiment, by setting the butterfly valves 3, it is convenient to regulate the inlet and outlet air volumes and the opening and closing. Its structure is simple and easy to use.
[0041] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
