Problems solved by technology
In the process of steelmaking, it is difficult to carry out backwashing operation, and the filtering effect of the filter is not good, which makes the dust removal nozzles easy to block, affects the dust removal effect at all levels, causes emission, and red smoke from the chimney; at the same time, it affects the rhythm of steelmaking production, Reduced steelmaking productivity
[0003] With the existing technology, the nozzles will be blocked every day. Workers use the time (40 minutes) for repairing the converter or replacing the steel hole to remove the manhole to clean the nozzles. The fine dust removal and coarse dust removal nozzles can only be carried out during the next furnace repair time, and at least three workers are required to handle them during this period

The invention discloses a one-time dedusting water purification system for steelmaking, which comprises a dedusting water header pipe, wherein the dedusting water header pipe is provided with a header pipe filter; the purification system is provided with a plurality of dedusting points for one-time dedusting in a dust catcher at the rear of the header pipe filter; the header pipe filter is connected to each dedusting point through a dedusting water branch pipe; and each dedusting water branch pipe is provided with a secondary filter. By adopting the technical scheme, the operation of cleaningand replacing filter nets on line is applied so as to quickly and conveniently purify dedusting water, improve the quality of the dedusting water, and ensure the water pressure and flow at each dedusting point and dedusting effect; meanwhile, the workload of workers is greatly reduced and the labor intensity of the workers is reduced.
Description
technical field [0001] The invention belongs to the technical field of metallurgical industrial production, and relates to dust removal and purification technology in metallurgical industrial production, in particular to a steelmaking primary dust removal water purification system. Background technique [0002] At present, in the first dust removal operation of steelmaking, the purification system of dust removal water only has a first-level purification device, and its structure is: a main pipe filter is installed on the main pipe of dust removal water. The pipe diameter increases; at the same time, the operation is generally manual. In the process of steelmaking, it is difficult to carry out backwashing operation, and the filtering effect of the filter is not good, which makes the dust removal nozzles easy to block, affects the dust removal effect at all levels, causes emission, and red smoke from the chimney; at the same time, it affects the rhythm of steelmaking producti...
