Description
Technical Field
[0001] The present application belongs to the technical field of dry quenching coke, and specifically relates to a dry quenching coke system. Background Art
[0002] In recent years, as national environmental protection requirements have intensified, energy conservation and emission reduction have become top priorities for corporate development. As a heavy industry, steelmaking should proactively respond to this call. Coke, as a reducing agent and the backbone of the blast furnace, is a crucial component of the ironmaking process. After being ejected from the coke oven, coke must be cooled before it can be shipped as a finished product. This cooling process is known as quenching. Because uncooled, red-hot coke contains significant heat energy and can generate gas, steel mills have generally abandoned water cooling, which is highly polluting and lacks heat recovery, and have instead adopted dry quenching (CDQ) to cool the coke.
[0003] In existing technology, many coking plants were built with incomplete coke dry quenching technology, resulting in insufficient space for dry quenching equipment. Furthermore, steel mills use parallel coke ovens. To maintain maintenance without interrupting operations, at least two dry quenching units (one active and one backup) are required to complete coke dry quenching. If multiple coke ovens are arranged in parallel, more units are required, and the backup units cannot be shared. This not only wastes dry quenching equipment resources, but also increases land usage and costs. Summary of the Invention
[0004] In order to solve the technical problem that coke dry quenching currently requires two dry quenching devices to be installed on one coke oven to ensure maintenance without stopping the operation, the present application provides a coke dry quenching system.
[0005] The present application provides a coke dry quenching system, comprising a coke dry quenching chamber, a first coke quenching unit and a second coke quenching unit.
[0006] The first coke quenching unit and the second coke quenching unit are arranged in the dry quenching chamber, and each includes a coke oven, a dry quenching device and a coke quenching car, and the coke quenching car is connected to the transport track in a rolling manner. In the first coke quenching unit and the second coke quenching unit, the coke ovens are provided with at least two and are arranged on the transport track;
[0007] Specifically, in the first quenching unit, two dry quenching devices are provided, which are respectively close to the two coke ovens; in the second quenching unit, one dry quenching device is provided, which is close to one of the coke ovens, and the other coke oven is close to a lifting device. The lifting device is provided at the end of the transport track and is connected to the dry quenching device of the first quenching unit.
[0008] In some embodiments, the lifting device is disposed on the top of the dry quenching chamber.
[0009] In some embodiments, the lifting device includes a telescopic claw, a slider and a first track provided at the top of the dry quenching chamber, the slider is slidably connected to the first track, and the telescopic claw is connected to the slider and can reciprocate along a direction perpendicular to the extension direction of the first track.
[0010] In some embodiments, the telescopic claw includes a mechanical claw and a telescopic member connected to each other, and the telescopic member can move back and forth in a vertical direction.
[0011] In some embodiments, there is one or two second quenching units.
[0012] In some embodiments, when two second quenching units are provided, the two second quenching units are respectively provided on both sides of the first quenching unit along the width direction of the first quenching unit transport track.
[0013] In some embodiments, when two second coke quenching units are provided, each of the lifting devices is connected to two of the dry quenching devices.
[0014] In some embodiments, in the first coke quenching unit and the second coke quenching unit, a plurality of coke ovens are provided, which are spaced apart along the extending direction of the transport track.

[0018] The dry quenching system of the present application is provided with a first quenching unit and a second quenching unit. Since the first quenching unit is provided with two dry quenching devices, the quenching car of the first quenching unit can transport the red coke in the coke oven of the first quenching unit to any one of the two dry quenching devices to complete the dry quenching operation. When any one of the dry quenching devices is under maintenance, the quenching car transports the red coke to the other dry quenching device to ensure that the maintenance does not stop the operation.
