Circulating water dust collection device of cupola furnace

Abstract

The invention discloses a circulating water dust collection device of a cupola furnace. The circulating water dust collection device is characterized by comprising an inner cavity and a water pump, wherein a cupola furnace connecting pipe, an upper tapered pipe, a gas collection pipe, a lower tapered pipe and a blow-down valve are arranged in the inner cavity in sequence from top to bottom; the connecting pipe is fixed to the upper part of the inner cavity; the upper tapered pipe is provided with an injection head; the injection head is connected with the water pump through a water pipeline; circulating water is stored into the lower part of the inner cavity; the circulating water is connected with the water pump through a water pipe, so that the circulating water is guided into a spraying head through the water pump and passes through a circulating water structure taking the gas collection and the lower tapered pipe as paths; an exhausting hole is further formed in an outer wall of the inner cavity. According to the circulating water dust collection device disclosed by the invention, gas collection is carried out through a special path; the path of the gas collection pipe is narrowed so that water mist sprayed out by the injection head is sufficiently cooled in the gas collection pipe and flue gas dust of the cupola furnace is absorbed; gas is sprayed out of the lower tapered pipe from the gas collection pipe, so that the flue gas dust of the cupola furnace is effectively absorbed.

Description

technical field [0001] The invention relates to the field of casting dust removal, in particular to a cupola circulating water dust removal device. Background technique [0002] my country is a big country of casting production. In the past, cupolas had no or only very backward dust removal equipment. The environmental protection department has stricter and stricter requirements on cupola dust removal. Many foundry manufacturers need to install or update dust removal equipment. Cupola swirl spray dust removal Due to many excellent performances, the purification system is very suitable for the needs of my country's foundry industry, and will become a very competitive equipment in the foundry production industry. [0003] A patent No. 201520269897.8 previously disclosed by an applicant is a patent for a spray dust collector called a cupola swirl spray dust removal device. The dust is removed by double spraying, but this technology has a large loss of circulation, and The gas i...

[0003] A patent No. 201520269897.8 previously disclosed by an applicant is a patent for a spray dust collector called a cupola swirl spray dust removal device. The dust is removed by double spraying, but this technology has a large loss of circulation, and The gas is directly sprayed by water, and the path after spraying is not set, which reduces the dust removal efficiency of the entire equipment
