A sintering machine flue gas condensation dust removal and demisting device

Abstract

The invention is applicable to the technical field of dust and mist separation, and provides a sintering machine flue gas condensation dedusting and demisting device, which includes a flue, a condensation dedusting module, a demisting device and a fixing device. The rinsing device includes a rinsing water pipe and a rinsing nozzle; the defogging device includes a fixed plate, a defogging blade and a structural beam, and the defogging blade is arranged in a V shape; the fixing device includes a base, an eccentric, an extrusion block and a screw, and the base is There are sliding grooves and limit grooves, the eccentric member is provided with an arc-shaped plate, the fixed plate is provided with a groove for accommodating the eccentric member, and the inner side of the groove is provided with a limit column, the limit column abuts the arc-shaped plate, and the extrusion block is bent. Folded and formed, the rotating shaft is sleeved with the screw, and the fixing plate is located under the end of the extrusion block. Thereby, the present invention can effectively realize the dust removal and separation of smoke, improve the separation efficiency, and at the same time facilitate the realization of detection and maintenance.

Description

technical field [0001] The invention relates to the technical field of dust and mist separation, in particular to a device for condensing, dedusting and demisting of flue gas of a sintering machine. Background technique [0002] In 2018, Hebei, Shanxi, Tianjin and other places successively issued documents on the in-depth control of air pollutants in key industries such as iron and steel sintering machines, coking, and coal-fired power plant boilers. The document requires the treatment of gypsum rain and colored smoke plumes, reducing the temperature and moisture content of flue gas emissions through corresponding technologies, collecting moisture in supersaturated water vapor in flue gas, and reducing soluble salts, sulfuric acid mist, organic matter in flue gas. Emissions of condensed particulate matter. [0003] In March 2020, Handan City issued the "Implementation Plan for In-depth Air Pollution Control in Key Industries of Industrial Enterprises in Handan City in 2020"...

AI Technical Summary

Problems solved by technology

[0007] There are problems in the existing technology: first, the water used for cooling is in direct contact with the high-temperature flue gas, which increases the amount of mist droplets in the flue gas while reducing the temperature of the flue gas, and increases the demisting pressure of the subsequent demister, resulting in smoke Water in the air is serious, affecting the back-end equipment

The second is that the water collecting tray increases the resistance of the flue gas, resulting in high fan output requirements and high operating power consumption

Fourth, the water spray cooling causes the water consumption of the system to increase a lot, and the water balance of the whole system cannot be guaranteed

Fifth, due to the characteristics of sintering flue gas, the traditional demisting device is easy to block. Once blocked, the device can only be repaired after the unit is shut down and no flue gas passes through.

[0008] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
