Pulse Jet Single Baghouse Dust Collector

Pulse Jet Single Baghouse Dust Collector(also known as single-unit pulse-jet bag filter,commonly referred to as DMC-type in industrial specifications)is a compact,standalone,high-efficiency dry dust collection system.It integrates filtration,automatic pulse-jet cleaning,dust collection,and exhaust functions into one integrated unit,designed for capturing and filtering fine particulate matter(PM)from local or small-scale industrial dust sources.

Working Principle

Filtration Stage:Dust-laden gas is drawn into the unit via the fan-induced negative pressure.Coarse dust particles settle into the hopper by gravity,while fine particles adhere to the outer surface of filter bags,forming a dust cake.Clean air permeates through the filter media into the clean air chamber and is discharged.

Pulse-Jet Cleaning Stage:As dust accumulates,the pressure drop(ΔP)rises.The controller triggers solenoid and pulse valves to release high-pressure compressed air(0.5–0.7 MPa)instantaneously.This creates a powerful reverse air pulse,causing the filter bags to vibrate violently and detach the dust cake,which falls into the hopper for discharge.

Core Structural Components

Main Housing&Tube Sheet:Robust steel casing with a perforated tube sheet to secure and suspend filter bags.

Filter Bags&Cages:High-performance filter media(polyester,PPS,PTFE)supported by metal cages to prevent collapse.

Pulse Cleaning System:Compressed air tank,pulse valves,solenoid valves,and blowpipes with precision nozzles.

Centrifugal Fan:Built-in exhaust fan providing negative pressure for air induction and clean air discharge.

Dust Hopper&Discharge:Conical hopper with rotary airlock valve or manual discharge for collected dust.

Electronic Controller:Programmable logic controller(PLC)or timer to automate cleaning cycles based on time or differential pressure.

Differential Pressure Gauge:Monitors filter resistance to indicate cleaning requirements.

Key Performance Advantages

Ultra-High Efficiency:Filtration efficiency≥90%,capturing particles as small as 0.3μm,meeting strict environmental emission standards(≤30 mg/m³).

Powerful Online Cleaning:The pulse-jet system enables uninterrupted operation,with strong cleaning energy and minimal air consumption.

Compact&Integrated:Small footprint,self-contained design(fan,controller,and hopper included),easy to install and relocate.

Low Maintenance:Tool-free filter bag replacement,long service life(6–12 months),and simple daily upkeep.

Wide Adaptability:Handles high dust concentrations and temperatures(up to 280°C with special media)across various industrial conditions.

Typical Applications

Metalworking:Welding fumes,grinding,plasma cutting,and polishing dust.

Woodworking:Sawdust,sanding dust from furniture and wood processing.

Building Materials:Cement,concrete batching,mineral powder,and ceramic processing.

Chemical&Pharmaceutical:Fine chemical powders,tablet dust,and raw material handling.

Food&Feed:Grain milling,sugar,flour,and feed processing dust.

Mining&Metallurgy:Ore crushing,screening,and non-ferrous metal smelting fumes.
