Abstract

The invention discloses a device and method for re-recycling dedusted coke powder. The device comprises a coal mill and a tank truck, wherein a powder inlet is formed in the sidewall of the coal mill and is connected with a one-way valve, the one-way valve is connected with a first pipeline, a first hand valve which is used for being connected with an ash conveying pipe of the tank truck is arranged at one end, far away from the one-way valve, of the first pipeline, an anti-blocking communicating valve is arranged on the first pipeline located between the one-way valve and the first hand valve and is connected with a second pipeline, one end of the second pipeline is connected with a nitrogen gas chamber, and a second hand valve which is used for being connected with a pulse duct of the tank truck is arranged at the other end of the second pipeline.

Description

technical field [0001] The invention relates to a coking and dust-removing powder device, in particular to a device and a method for reusing the coking and dust-removing powder. Background technique [0002] At present, coke CDQ is commonly used in domestic blast furnace ironmaking, and dust is inevitable in the production process of CDQ, and dust removal by bag is usually used for use. However, how to reuse the collected dedusted coke powder is a difficult problem. Now it is common to mix the collected CDQ dedusted powder into sintering, and during the sintering process of laying CDQ dedusted powder, the secondary dust is serious, and the environmental protection monitoring is not enough. , Increase cost, low utilization rate, waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a device and method for recycling the coking dust removal powder again in view of the above shortcomings of the prior a...
