DDC-JD Series Single Arm Welding Fume Extractor

The DDC-JD Series Single Arm Welding Fume Extractor is specifically suitable for purifying fumes and dust generated in welding and grinding processes. The equipment boasts high purification efficiency and good adaptability to meet the needs of various working environments.

Applicable Scope

Designed for smoke and dust purification in processes such as welding, polishing, cutting, and grinding. Suitable for work environments that require localized purification of fumes and dust.

Working Principle

Upon activation, the fan creates a negative pressure system that draws in fumes and dust. The fumes and dust are passed through a filtration system where particles are captured by the filter cartridges. The cleaned air is then emitted back into the workspace.

Main Features

Core Components of Dust Removal

Filter Elements

High-efficiency filter cartridges: Made from PTFE coated long-fiber polyester non-woven material, they effectively capture dust particles larger than 0.3 microns, with a purification efficiency of up to 99.9%.
The filter cartridges are durable and can operate under high pressure, offering a long service life.

Operational State

The filter cartridges operate in a ventilation state, cleaned through pulse jet cleaning to maintain filtering efficiency.

Pulse Jet Cleaning System

Pulse jet cleaning uses compressed air to generate pulsed airflows that blow off the accumulated dust from the filter cartridges, keeping them clean.
These components are crucial for the dust removal system, ensuring effective capture and purification of fumes and dust.

Technical Parameters

Core Components of Dust Removal

High filter cartridge as the filtering element, PTFE membrane filter, for the adhesion of dust,PTFE coated filter element can filter dust particles reach 0.3um (optonal higher eve of filtraton), the filtration efficiency reached 99.99%.Even if the ambient temperature is lower than the dew point temperature. The filter element also maintains a stable filtration capacity.PTFE membrane filter has the advantages of membrane filtration and rigid body filtration, and small volume, large filtration area of rigid filter allows high working pressure, and has a very long service life. Mainly used for the treatment of various toxic and harmful ultrafine dust and smoke, caution should be exercised in oily smoke environments, and additional membrane materials may be required for use.

Self-cleaning Principle of Cartridge

Purifier filter cleaning by pulse jet structure: when the purifier running after a period of time, fine dust adsorbed on the surface of the filter, the reduced permeability filter, dust absorption filter surface is cleared in the flow, fall in the lower chamber of the dust hopper.

Pulse injection requires clean compressed air of 0.4-0.6Mpa, and constant and constant air supply must be maintained during operation.

Ash Cleaning System

Cartridge filter cleaning with compressed air pulse cleaning, now through the microcomputer control timing or manual start function of pulse jet injection valve, the filter cylinder radial deformation, shake off the dust. The pipeline system is fixed in the box with the support, and the positioning pin is set, so that the accurate reset can be ensured when the equipment is maintained and maintained.

Compressed air piping system for diversion of compressed air, compressed air helps in the blowing process stability, can improve the cleaning system running stability, effectively reduce the equipment running resistance, reduce the energy consumption of the system. The ash cleaning system is equipped with gas distribution bag and precision filter (oil, water and dust) to ensure the pressure, gas volume and quality of the gas supply. The dust cleaning and ash cleaning capacity can meet the demand of dust cleaning under various working conditions.

Electromagnetic Pulse Valve

The key equipment of the ash cleaning system is the electromagnetic pulse valve, and its selection is related to the dust removal effect of the dust remover and the stability and reliability of the equipment. Can effectively reduce the operation and maintenance costs. We use the electromagnetic pulse valve to dust, blowing pressure 0.7MPA, DC24V 1.0"in the workload, gas pressure is MPA, pulse jet time 0.2S, single electromagnetic pulse valve injection when the compressed air consumption 30L, greatly reduce the compressed air consumption, can effectively reduce the workload of the compressed air station.
