Dust collection device

Abstract

The invention relates to a dust collection device. The dust collection device comprises a box body, a gas inlet pipe, a discharging pipe and a water inlet pipe, wherein the upper part of the box body is separated into a dust collection box and an observation chamber through a separation plate; the lower spaces of the box body are communicated; a water seal is arranged in the dust collection box; a grating plate is arranged on the top of the dust collection box; the gas inlet pipe is inserted into the dust collection box through the grating plate. According to the dust collection device, smoke dust tail gas of an industrial furnace enters the water seal in the dust collection box through the gas inlet pipe, gas overflows from the grating plate, and smoke dust is gathered in water, so that valuable metal is recovered, and air pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of flue gas treatment, in particular to a flue gas dust collecting device for an industrial furnace. Background technique [0002] When non-ferrous metals are smelted by fire, a part of the charge will fly out from the chimney with the exhaust gas of the industrial furnace, resulting in a decrease in the actual yield of metals, especially for precious metals, resulting in large economic losses for the enterprise. At the same time, the dust covering the workplace causes air pollution and affects the health of operators. At present, equipment manufacturers generally install dust collection bags in the exhaust pipes of industrial furnaces. However, due to the pores in the dust collection bags, fine particle powder will still pass through the bags and fly from the chimney into the atmosphere. Contents of the invention [0003] The invention provides a dust collection device, the purpose of which is to settle ...

At the same time, the dust in the workplace causes air pollution and affects the health of operators

At present, equipment manufacturers generally install dust collection bags in the exhaust pipes of industrial furnaces. However, due to the pores in the dust collection bags, fine-grained powder will still pass through the bags and fly from the chimney into the atmosphere.
