Flue gas purification system of casting blank arc angle forming device

Abstract

The invention discloses a flue gas purification system of a casting blank arc angle forming device. The flue gas purification system comprises a flue gas collection cover, a flue gas purification device, an induced draft fan and other main equipment. The device is mainly characterized in that a flue gas collecting cover, a dust removal air pipe, a flue gas purifying device, a fan connecting pipe, an induced draft fan and a chimney are sequentially connected, and flue gas generated by an arc angle forming device is collected in the flue gas collecting cover, sucked into the flue gas purifying device by the induced draft fan to be purified and then discharged through the chimney. The problems that a casting blank arc angle forming device is difficult in smoke collection, high in temperature, large in smoke amount, low in purification efficiency and the like are effectively solved, efficient smoke purification of the casting blank arc angle forming device is achieved, and the smoke purification system is energy-saving and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a flue gas purification system of a billet arc angle forming device. Background technique [0002] The billet arc corner forming device (authorized publication number CN108339955B) uses the continuous casting slab corner cleaning burner (authorized publication number CN208595542U) to mix and burn oxygen and fuel gas, preheat the slab to form a molten pool, and then use high-pressure pure Oxygen flow reacts with the corners of the continuous casting slab and removes steel slag, thereby removing corner defects and forming smooth arc corners. During the cleaning process, the iron-oxygen reaction produces a large amount of flue gas, which contains a large amount of iron oxide dust. The direct emission of flue gas is bound to endanger the health of workers and pollute the environment. [0003] The flue gas generated by cleaning the slab arc corner forming device is sprayed alon...

AI Technical Summary

Problems solved by technology

After actual use, it is found that the efficiency of traditional electrostatic dust removal is not high, and yellow smoke appears, which obviously does not meet the environmental protection emission requirements

In addition, the electrostatic dust removal equipment has the disadvantages of large investment and large floor area, which is not conducive to the investment and construction of the billet arc corner forming device
