Embodiment 1

[0053] The process of the high-efficiency dust removal system for dust first collects the dust airflow from each dust-producing area and sends it to the pre-sedimentation device for pre-sedimentation, and separates and collects large particles of dust with a particle size of more than 50 μm from the dust airflow; after pre-sedimentation treatment The final dust airflow is sent to the bag type dust removal device for pulse bag type dust removal, and the clean air is discharged directly; the dust obtained by the pulse bag type dust removal and large particle dust are sent to the ash storage bin for storage at the same time; and then discharged into the discharge bin The dust is sprayed with water mist and stirred continuously for 1 min; then the dust is sprayed with foam before loading into the truck.

Embodiment 2

[0055] The process of the high-efficiency dust removal system for dust first collects the dust airflow from each dust-producing area and sends it to the pre-sedimentation device for pre-sedimentation, and separates and collects large particles of dust with a particle size of more than 50 μm from the dust airflow; after pre-sedimentation treatment The final dust airflow is sent to the bag type dust removal device for pulse bag type dust removal, and the clean air is discharged directly; the dust obtained by the pulse bag type dust removal and large particle dust are sent to the ash storage bin for storage at the same time; and then discharged into the discharge bin The dust is sprayed with water mist and stirred continuously for 30 minutes; and then the dust is sprayed with foam before loading and transporting.

Embodiment 3

[0057] The process of the high-efficiency dust removal system for dust first collects the dust airflow from each dust-producing area and sends it to the pre-sedimentation device for pre-sedimentation, and separates and collects large particles of dust with a particle size of more than 50 μm from the dust airflow; after pre-sedimentation treatment The final dust airflow is sent to the bag type dust removal device for pulse bag type dust removal, and the clean air is discharged directly; the dust obtained by the pulse bag type dust removal and large particle dust are sent to the ash storage bin for storage at the same time; and then discharged into the discharge bin The dust is sprayed with water mist and stirred continuously for 15 minutes; and then the dust is sprayed with foam before loading into the truck.

Abstract

The invention discloses a high-efficiency dust removal system for dust, which includes a pre-sedimentation device, a bag-type dust removal device, an ash storage bin, and a discharge bin; Bag-type dust removal device treatment, and greatly reduce the maintenance frequency of bag-type dust-removal device, improve the service life of filter bags; bag-type dust-removal device cooperates with water mist spray, wet mixing and foam spraying, which is not only conducive to the storage of dust in the ash storage bin, And it is convenient to unload the dust. The invention also discloses a process of a high-efficiency dust removal system for dust, including the steps of pre-sedimentation, bag dust removal, storage, water mist stirring and foam spraying; the process of the invention separates large particle dust in advance, and then carries out bag dust removal, which has the advantages of The advantages of high dust removal efficiency and reduced maintenance frequency; before the stored dust is transported, it is sprayed with water mist and stirred continuously, and then sprayed with foam, which can effectively reduce the problem of secondary dusting of dust.

Description

technical field [0001] The invention belongs to the technical field of dust control, and in particular relates to a high-efficiency dust removal system and technology. Background technique [0002] During the production process of the blast furnace for ironmaking, the problem of dust flying in the unloading area, feeding area, weighing area, skip area, raw material conveying area and storage area on the trough is serious. The continuous flying dust permeates in the factory building and overflows outside the factory building, causing serious environmental pollution in the factory building and surrounding areas, and also endangering the physical and mental health of the operators on the job site. For this reason, it is very necessary to develop an efficient dust removal system and process that can solve the above problems. Contents of the invention [0003] The first object of the present invention is to provide an efficient dust removal system for dust. [0004] The secon...
