Abstract

The invention discloses a wet-type blower fan foam whirling current dedusting treatment device, which comprises a foam generation apparatus, a dedusting blower fan, a dedusting / demisting treatment device amd a foam injection apparatus arranged at an air inlet of the dedusting blower fan. The treatment device uses a principle of performing foam dedusting, de-watering and demisting by high-speed rotating spiral airflow and performing eddy flow centrifuge dewatering to perform high efficiency separation on a dust-water mixture in air flow. A special filter screen structure of the dedusting / demisting processing apparatus form eddy current rotation of ventilating current and form viscous liquid film on the filter screen, strong dust adsorption is carried out to realize high efficiency separation of the dust-water mixture, so that multistage dust depositing effect can be reached. The dedusting efficiency can reach more than 99%, dedusting efficiency of respirable dust can reach 95%, processing maximum air flow can reach 900m<3> / min, the processed ventilating current enable dust and mist-free cleaning, and work environment of safe production under well can be ensured.

Description

Technical field [0001] The invention relates to a dust removal fan, in particular to a foam vortex flow dust removal treatment device for a wet fan. Background technique [0002] Along with the improvement of the mechanized production level in the mine production process, the dust production at various working points of the mine has increased sharply, which seriously threatens the safety of mine production and the health of employees. [0003] In the prior art, dust extraction and purification technology is commonly used, that is, dust is extracted from coal mining work by a dust removal fan, and then is discharged after purification. [0004] The key equipment of the dust extraction and purification technology is the dust removal fan. Under the specific working conditions of the coal mine, the dust removal fan must not only maintain a large processing air volume, but also ensure a high dust removal efficiency, while ensuring a normal underground operating environment. [0005] Howeve...
