Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of metallurgical coking, and in particular relates to a cleaning device for the interior of a coke oven body. Background Art
[0002] During the operation of the coke oven, as time goes by, some dust will inevitably accumulate inside the coke oven body: for example, the small flue, exhaust gas tray, heat storage top lattice bricks, inclined area, etc. The increase in dust accumulation will seriously affect the airflow distribution in the coke oven body and affect normal heating, so it must be cleaned.
[0003] The traditional cleaning device and method are very simple, using a compressed air pipe to penetrate deep into the furnace and blow directly. However, there are the following disadvantages: the smoke and dust blown away with the exhaust gas will directly enter the chimney, causing the online monitoring data of the chimney particulate matter to increase and exceed the standard, which is not in line with the current environmental protection requirements. In addition, for the dust in some areas, the dust will be blown into another area during the blowing process and cannot be completely discharged from the furnace body.
[0004] Therefore, existing technology must be improved, and it is necessary to invent a novel coke oven body internal cleaning device. Utility Model Content
[0005] In view of the problems existing in the prior art, the utility model provides a coke oven body internal cleaning device.

[0007] A coke oven internal cleaning device comprises a herringbone-shaped main body; the top port of the main body is an outlet; a port at the bottom of the main body is connected to a suction pipe; another port at the bottom of the main body is connected to a compressed air pipe; the suction pipe is a metal hose; the compressed air pipe is connected to the main body through a compressed air pipe joint; the suction pipe is connected to the main body through a suction pipe joint.
[0008] In a feasible technical solution, heat insulating cotton is wrapped around the main pipe.
[0009] In a feasible technical solution, the main pipe body includes a collecting pipe and two branch pipes, wherein: one end of the collecting pipe is an outlet, and the other end of the collecting pipe is connected to a branch pipe as a whole; a compressed air injection port is opened on the side wall of the collecting pipe; the compressed air injection port is connected to another branch pipe; and the angle between the two branch pipes ranges from 10° to 60°.
[0010] In a feasible technical solution, the angle between the two branch pipelines is 30°.
[0011] In a feasible technical solution, the collecting pipeline and the two branch pipelines are an integrally formed structure.
[0012] In a feasible technical solution, the inner diameter of the compressed air pipe is smaller than the inner diameter of the suction pipe.
[0013] Compared with the prior art, the advantages and positive effects of this application are:
[0014] The utility model utilizes compressed air injection to generate suction. Compressed air is always available in the coke oven area of the coking plant and can be used everywhere. It is easy to use and inexpensive. The principle of negative pressure dust suction is utilized to directly suck out the accumulated ash inside the furnace body. During the cleaning process, the accumulated ash and dust will not be brought into the exhaust gas system and discharged into the chimney, and will not affect the online monitoring data of the chimney particulate matter. The interior of the cleaning device is hollow and has no other components. Therefore, clogging will not occur, and even if there are some small pieces of mud or broken bricks, they can still be sucked out. BRIEF DESCRIPTION OF THE DRAWINGS
