Problems solved by technology

[0004] However, in the actual operation process, it was found that because the high-temperature water vapor is mixed with dust impurities such as fine coke powder, during the process of steam treatment, these impurities also enter the pipeline of the steam absorption device along with the steam, and after being combined with condensed water Viscous substances will be formed and attached to the inner wall of the pipeline, and the pipeline is easily blocked, which seriously affects the normal operation of the water addition, humidification, dust reduction system

Abstract

The invention relates to a steam absorption system used during water adding, humidifying and dust falling of a coke intermediate bin. The steam absorption system comprises a suction hood arranged on the upper portion of the coke intermediate bin and a steam absorption device connected with the suction hood through a steam pipeline. The steam absorption system further comprises a dust removal pretreatment device and an induced draft fan; and the dust removal pretreatment device is provided with a steam inlet so as to be connected with the suction hood, is provided with a steam outlet so as to be connected with the steam absorption device, and is provided with a water and dust outlet so as to be connected with the coke intermediate bin. According to the steam absorption system, high-temperature steam led out of the coke intermediate bin is subjected to filtering pretreatment before entering the steam absorption device, dust and water in the high-temperature steam are filtered out, and then the high-temperature steam without the dust and the water is sent back to the coke intermediate bin, so that pipeline blockage in a follow-up system is effectively prevented, and efficient and normal operation of a water adding, humidifying and dust falling system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coke dry quenching, in particular to a steam absorption system for adding water to a coke tundish for humidification and dust reduction. Background technique [0002] In the coking industry, coke CDQ has been popularized as a mature energy-saving and emission-reduction process. The temperature of the coke discharged to the cold coke transportation system after CDQ is relatively high, and a large amount of dust will be generated during the transportation and transfer of cold coke. Initially, the common practice in the industry was to set up a dust removal cover at the transfer point of cold coke transportation, and discharge the generated dust after being treated by an in-situ dust collector or a centralized dust removal ground station. Dust will still be raised during transportation, and it will also increase the power consumption and maintenance costs of the dust removal system. Later, the industry gen...
