Stainless steel smelting dust removal device

Abstract

The invention discloses a stainless steel smelting dust removal device. A device body is sequentially provided with a purified gas collecting chamber, a purifying treatment chamber and a dirt collecting chamber from top to bottom; a demister is fixedly arranged between the purified gas collecting chamber and the purifying treatment chamber; a spraying device is fixedly arranged at the center of the middle part of the purifying treatment chamber; the spraying device is connected with an external high-pressure water source through a pipe; a gas distribution box is further fixedly arranged rightbelow the spraying device in the purifying treatment chamber; a plurality of gas outlets are formed in the whole lower surface of the gas distribution box; a gas inlet pipe communicated with the innercavity of the gas distribution box is connected to one side of the gas distribution box; the gas inlet pipe runs through the device body; an exhaust port is formed in the purified gas collecting chamber; the dirt collecting chamber is provided with a drainage pipe; a valve body is arranged on the drainage pipe. The stainless steel smelting dust removal device can perform dust-removing and coolingoperations at the same time, so that air temperature rise caused by flue gas emission into air can be avoided; meanwhile, the stainless steel smelting dust removal device is low in maintenance rate,so that the problem of utilization rate decrease caused by maintenance can be avoided.

Description

technical field [0001] The invention relates to the field of dust removal in smelting, in particular to a dust removal device for stainless steel smelting. Background technique [0002] The smelting of iron and steel usually produces a large amount of high-temperature flue gas, which not only has a high temperature, but also contains toxic and harmful gases and a large amount of dust, which will cause serious harm to the surrounding environment and the health of the surrounding people, so it must be dust-removed It can only be discharged after purification. The existing dust removal devices for smelting have low dust removal efficiency, and most of them only have the function of dust removal, and do not have the function of cooling the flue gas. This will easily lead to the high temperature of the purified air, which will aggravate the greenhouse effect. In addition, the existing dust removal devices used for smelting often use filter bags to remove dust. The filter bags in...
