AI Technical Summary

Technical Problem

Traditional pulse jet dust collectors have low cleaning efficiency when dealing with high humidity and high viscosity dust, which easily forms a dense dust layer, increases filtration resistance, and poses a risk of secondary caking, affecting the long-term stability of the equipment.

Method used

A steam mixing three-way valve is added between the high-pressure air source and the main pipe to form a humid and hot mixed pulse airflow. The slightly superheated steam softens the caking dust and melts the frost. Combined with the variable diameter nozzle design, it achieves efficient dust removal and prevents secondary caking.

Benefits of technology

It significantly improves dust removal efficiency, prevents dust from re-adhering, extends the life of filter bags, reduces maintenance frequency, and lowers energy consumption.

Abstract

The utility model provides a kind of pulse cloth bag dust collector, including support system, dust removal bin, air inlet, bottom, installation layer, top cover, the top of the support system is fixedly connected with dust removal bin, the side low of the dust removal bin is fixedly connected with air inlet, the bottom of the dust removal bin is fixedly connected with bottom;The inside upper portion of the dust removal bin is fixedly connected with an installation layer.The utility model has the advantages that compressed air is slightly superheated steam, forms humid heat mixed pulse airflow from spray head, high-efficiency debonding defrosting: humid heat airflow can soften hardening dust, melt frost, significantly improve dust removal efficiency (especially for cement, chemical industry, food and other high-humidity viscous dust).Prevent secondary hardening: short-time high-temperature steam evaporates residual moisture. Variable-diameter spray head design: spray head adopts tapered taper hole (large inlet, small outlet), airflow produces sustained impact force on hardening area, similar to the effect of "high-pressure water gun flushing".
