Anti-scaling evaporation cooling equipment for primary dry dedusting of converter

Abstract

The invention relates to an anti-scaling evaporation cooling equipment for primary dry dedusting of a converter. The anti-scaling evaporation cooling equipment comprises an anti-scaling evaporation cooler (2), an elbow deduster (3), a double-medium tempering spray gun (5), a double-medium cooling spray gun (6) and a fluidization back-flushing deashing device (15). A high-temperature-resistance nonmetal compensator (1) is arranged at an inlet of the anti-scaling evaporation cooler (2), the elbow deduster (3) is arranged at an outlet of the anti-scaling evaporation cooler (2), and the fluidization back-flushing deashing device (15) is arranged around the anti-scaling evaporation cooler (2). By the equipment, the problem of hole forming on a vaporization cooling flue of a double-flow spray gun is solved, the problem that the inner wall of an evaporation cooling tower is prone to scaling is solved, and the problem that dust discharging of a diffusing chimney at the early stage of smelting of the converter, at the stage of secondary gun lowering and at the later stage of smelting does not reach the standards is solved. The anti-scaling evaporation cooling equipment is especially suitable for projects of primary smoke wet dedusting to dry dedusting of the converter and is wide in application prospect.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, more specifically, to a primary dry dedusting anti-fouling evaporation cooling equipment for a converter. Background technique [0002] With the continuous strengthening of environmental protection awareness, most of the newly built and rebuilt converters adopt dry dust removal system. The conventional layout of the dry dedusting equipment in the converter main workshop is as follows: the double-flow spray gun is installed at the end of the evaporative cooling flue, spraying water mist into the evaporative cooling tower to cool down and reduce dust, and to condition the raw gas; the coarse ash collected by the banana bend passes through the The built-in double chain conveyor sends it to the coarse ash bin, which is transported by the ash truck. [0003] The main problems of the existing primary dry dedusting equipment for converters are as follows: first, the double-flow spray g...

Problems solved by technology

[0003] The main problems of the existing primary dry dedusting equipment for converters are as follows: first, the double-flow spray gun is installed at the end of the vaporization cooling flue, and holes need to be opened in the vaporization cooling flue, especially in the transformation project of wet method to dry method dust removal, the vaporizer must be replaced The end of the cooling flue increases equipment investment and installation difficulty; second, the inner wall of the evaporative cooling tower is prone to fouling, and the built-in double-chain conveyor has a high failure rate, which is easy to get stuck, which affects the normal production of the converter; third, in the initial stage of converter smelting, The second shot and the release of smoke from the chimney in the later stage of smelting, the dust emission is not up to standard, polluting the environment
