Oil fume gas carrying harmful pollutants enters the fume filter tangentially through the Venturi spraying section. After the airflow accelerates in the front-stage Venturi spraying zone, the washing water is atomized into fine water curtains. The high-speed relative rotation between airflow and washing water enables the pollutant-laden medium to fully mix with the water curtain, followed by oil-water separation from the airflow inside the fume filter. Separated oily wastewater flows back through the drain pipe into a circulating water tank equipped with an automatic oil skimmer at the bottom. Clean air is exhausted to the atmosphere via an induced draft fan. Floating oil on the surface of the circulating water tank is skimmed by the automatic oil skimmer, scraped into an oil drum for regular centralized disposal.
Venturi wet dust collectors are applicable to dust removal and purification in all production scenarios and can treat almost all waste gas and dust generated during manufacturing processes. It achieves a dust removal efficiency of over 99% for particulate matter larger than 1 micron, with the following major advantages:
Safe operation and high separation efficiency
Small floor space with modular structure design
Compliant with the latest national environmental emission standards
Easy maintenance, lowering daily upkeep costs
Wide range of applications, suitable for all industries
Safe for flammable and explosive waste gas and dust, effectively eliminating fire and explosion risks
No filter cartridge replacement required. Dust is captured using water as the medium, resulting in no follow-up consumable costs
Pre-spraying can be installed inside pipelines to handle special sticky and oily dust
An optional oil-water separator can be equipped for oil fume treatment to extend the wastewater discharge cycle
A filter press can be optionally installed at the bottom for non-ferrous metal dust such as magnesium, aluminum and fine particles, realizing zero wastewater discharge
• Pre-spray devices with fire prevention, cooling and flushing functions installed inside pipelines to improve dust removal efficiency, cut operation and maintenance costs and eliminate potential safety hazards;
• Optional hydrogen detectors, hydrogen exhaust units and various explosion-proof configurations for explosion-proof industries to guarantee safe and efficient operation of dust collectors;
• Real-time monitoring of the spraying system, air volume and air pressure during operation to ensure the reliability and stability of the dust collector;
• Anti-freezing heating components for outdoor installation;
• Sludge loading and unloading trolley (swivelable and tiltable);
• Partial and overall noise reduction solutions.

FAQ
Q : What are the core advantages of Venturi wet dust collectors over dry dust collectors?
A: It is highly adaptable to oily, viscous, high-temperature, flammable and explosive dust (such as aluminum-magnesium dust, rubber dust, heat treatment oil fume and welding fume). It fundamentally avoids safety hazards including filter blockage, equipment fire and explosion. With no filter consumables required, it eliminates frequent filter replacement and greatly reduces later operation and maintenance costs. Equipped with a filter press, it realizes water recycling with superior environmental performance and economy.
Q : Is the equipment prone to clogging when handling viscous dust (rubber, wire drawing, machining oily dust)?
A: No clogging occurs. Adopting a simple spiral structure and an automatic pipeline pre-spray cleaning design, the equipment realizes full water washing purification without dead space for dust and oil accumulation. Different from traditional multi-baffle structures, it avoids dust and sludge deposition, perfectly solving the industrial pain point of pipeline and equipment clogging caused by viscous oil fume and oily dust.
Q : Is the operating cost high? Is the later maintenance complicated?
A: The operating and maintenance costs are extremely low. The equipment has no filters or high-frequency wearing parts, saving filter replacement costs. Built-in automatic cleaning function eliminates frequent manual cleaning of pipeline oil and dust deposits. Matched with a filter press, it supports water recycling, and dewatered dust can be recycled without a large amount of wastewater discharge, delivering far higher cost performance than traditional dust removal equipment in long-term operation.
Q : Can it be linked with industrial equipment such as die casting machines, extruders and punch presses?
A: It supports full-scene adaptation. Equipped with an automatic valve control system, it can operate in linkage with die casting machines, extruders, punch presses, shot blasting machines, smelting equipment and other devices. It automatically starts dust removal during production and shuts down in standby state for energy saving. The matched movable suction hood adapts to mold replacement and equipment maintenance with high flexibility. A terminal high-efficiency filter can be added for deep purification to achieve zero white smoke indoor discharge.
