Environment-friendly and energy-saving dust suppression system for hot slag braising process and using method thereof

Abstract

The invention discloses an environment-friendly and energy-saving dust suppression system for a hot slag braising process and a using method thereof. The environment-friendly and energy-saving dust suppression system comprises a main machine, a water inlet pipe, a water pipe, an air compressor, an air storage tank, a breather pipe, a large spray gun distributor, a lotus nozzle distributor, at least one slag braising pool and at least one vibrating screen. The dust inhibitor is added, the combination efficiency of water drops and dust is improved, a grouping and sectioning control mode is adopted, each slag pool adopts an independent control unit, and independent dust inhibition is carried out according to the actual field of each slag pool; by using the powder dust suppression additive, the defect of high consumption of dry fog dust suppression water is effectively overcome, the advantages of small occupied area, low energy consumption, simplicity and convenience in installation and the like of dry fog dust suppression are perfectly reserved, and the problems of huge dust removal system, energy waste, high construction and production cost, low dust removal efficiency, high maintenance cost and the like of the conventional slag braising pool are effectively solved.

Description

technical field [0001] The invention relates to a dust suppression system for a production process slag pool in a steelmaking plant of an iron and steel enterprise, in particular to an environment-friendly and energy-saving thermal slag process dust suppression system and a use method thereof. Background technique [0002] At present, domestic iron and steel enterprises have adopted a mode of leaving the factory closed after the slag pool is operated, reversed, and exported, and the dust and smoke gather inside and on the top of the factory building. The top, doors and windows overflowed, causing atmospheric pollution and visual pollution. Second, there was a large amount of smoke and dust floating on the roof of the factory building, and the dust on the posts inside the workshop seriously exceeded the standard. [0003] The comparison of technical methods is as follows: [0004] 1. Increase the large dust removal on the roof, that is, the three-time dust removal method (ke...

AI Technical Summary

Problems solved by technology

[0004] 1. Increase the large dust removal on the roof, that is, the three-time dust removal method (key air suction port on the ground): this method needs to set up a huge roof dust removal air volume, which requires large investment, high operating costs, difficult renovation and affects production during renovation; the original steel structure factory building The strength is not enough, reinforcement construction is required, and equipment installation needs to stop production for installation

In addition, it is impossible to set up an effective suction hood for the slag pool, and the same is true for the waste slag pile. It is difficult to organize dust collection in the area, and the effect is difficult to achieve the expected purpose, and it cannot guarantee drifting dust suction. This method is not applicable

[0005] 2. Use water spray dry fog to suppress dust: This method uses water atomization to suppress dust. Large water volume will easily cause secondary pollution. It can only be applied to areas where there are no electrical equipment, or areas where large water volumes are not afraid of pollution, or to products. Areas of work where quality is not compromised
