Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings, and the present invention is relatively clear to those skilled in the art.

[0013] Example 1. Through processing air volume of 50,000 to 500,000 Nm 3 The / h fan generates enough negative pressure at the suction hood to inhale the dust containing water vapor and oil fume generated during the rolling process, and the concentration is ≤ 10g / Nm through the air inlet pipe 3 , Dust with a temperature of ≤70°C is fed into the equipment, the resistance is ~1600Pa, the number of filter elements is 95-950 pieces, and the filtration area is 855-8550m 2 , The filtered wind speed is 1.016-0.975m / min, and the water and oil resistant filter element dust collector with air leakage rate ≤ 3, the dust is captured by the filter element and separated from the gas, and the dust emission concentration in the filtered clean gas is ≤ 20mg / Nm 3 . The dust collected by the filter element in ...

Abstract

A dust separator for controlling the powdered dust generated by metallurgical rolling by dry method is composed of sucking hood, air inlet tube, water and oil resistant filter-core type dust collector, air outlet tube, blower, exhausting pipe and dust discharging unit.

Description

[technical field] [0001] The invention relates to the technical field of mechanical dedusting devices, in particular to a dedusting device for controlling metallurgical hot rolling finish rolling dust by dry method. [Background technique] [0002] In the production process of metallurgical hot-rolled plates, the material, thickness and width of the steel plates rolled by the rolling mill are different, and the amount of dust produced will also be different. Because the billet is heated at high temperature, in order to protect and extend the life of the rolls on the rolling mill, it is stipulated in the rolling process that cooling water and lubricating oil must be sprayed to the rolls. In this way, a large amount of air masses composed of iron oxide dust, water vapor, oily smoke, etc. will be generated before the finishing mill, thereby polluting the environment and affecting the surface quality of the steel plate. [0003] In the past, wet dust removal equipment was used b...
