Abstract

The invention relates to a blast furnace top gas diffusing system. The blast furnace top gas diffusing system comprises a gas ascending pipeline. The gas ascending pipeline is connected with a gas recycling pipeline and at least one furnace gas diffusing pipeline. Furnace gas diffusing valves are arranged at furnace gas diffusing pipeline terminals. The blast furnace top gas diffusing system further comprises a dust removal chamber, the dust removal chamber is provided with an exhaust channel, the dust removal chamber is internally provided with an inner spraying mechanism for spraying water into a cavity of the dust removal chamber, and various furnace gas diffusing valves are all contained in the dust removal chamber. According to the provided blast furnace top gas diffusing system, thedust removal chamber is arranged to surround the various furnace gas diffusing valves, the inner spraying mechanism is arranged in the dust removal chamber, gas exhausted into the dust removal chamberis washed and subjected to dust removal, the cleanliness degree of the diffused gas is improved, and pollution of gas diffusing particles is reduced.

Description

technical field [0001] The invention belongs to the technical field of blast furnace production, and in particular relates to a blast furnace top gas release system. Background technique [0002] At present, there are mainly the following situations for the release of blast furnace top gas: [0003] Part of it comes from the diffused gas in the equalizing pressure diffused system. The blast furnaces built earlier, due to historical reasons, weighed the equalized gas in the tank and discharged it directly to the atmosphere; the blast furnaces built in recent years have adopted recycling measures due to cost pressure and environmental protection pressure. [0004] The other part comes from the release during the blast furnace shutdown: (1) Plan the shutdown situation. The common method is to release the early stage, the gas pressure is relatively high, and take recycling measures. When the gas pressure drops to 30kPa ~ 15kPa, in order to increase the gas discharge speed , to...
