Introduction to the “AoGong” Dry-Mist Dust Suppression System:
The dry‑mist dust suppression system employs a modular design, comprising a micron‑level dry‑mist dust suppressor, a dry‑mist enclosure, omnidirectional dry‑mist nozzles, an air compressor, an air storage tank, a self‑cleaning filter, water‑air connection pipelines, an electric heating system, and an automated control circuit.
Scope of Use
It is widely applicable to pollution sources in ports, thermal power plants, steel mills, mines, chemical facilities, and other settings where emissions are uncontrolled, as well as in enclosed or semi-enclosed spaces, significantly reducing the risk of dust explosions. (Examples include: car‑unloading halls, screening towers, transfer towers, crushing plant rooms, loading buildings, coal‑unloading chutes, coal‑storage hopper bins, belt‑conveyor outlets, conveyor transfer stations, and ship‑loading/unloading machines.)
Features of the dry-mist dust suppression system:
1. Ultra-fine atomization; average droplet size of 10 μm
2. The two‑fluid atomizer consists of a liquid‑flow control valve, a pneumatic control valve, and an atomizing nozzle. Through precise sequential automatic control, it directly converts liquid water into an ultrafine mist. The atomization principle relies on compressed air and water passing through a specialized differential‑pressure valve designed for proportional, flow‑type two‑phase atomization; the mixture is then atomized by a custom nozzle, enabling natural regulation of both the make‑up water and the compressed air under any operating conditions, thereby effectively suppressing dust.
3. The nozzle is made of stainless steel, features a large diameter, and is resistant to clogging. The water supply requires only simple filtration (around 5 μm) and can be connected to a water tank or compressed air, ensuring optimal atomization performance. Moreover, after prolonged periods of inactivity, this product requires no maintenance.
4. The economic performance is exceptionally favorable, enabling substantial savings in equipment procurement, installation, operation, and maintenance costs. With a relatively simple structure, it offers lower overall costs under high‑flow demand conditions.
5. Upon customer request, the entire system can be equipped with constant-temperature control to prevent low‑temperature freezing from causing system shutdown.

Principle of dry-mist dust suppression
The principle of dry‑mist dust suppression is based on research findings by European and American scientists: when the size of ice‑mist particles closely matches that of dust particles, the likelihood of adsorption, filtration, and agglomeration is maximized. Micron‑scale dry‑mist dust‑suppression systems exhibit dust‑control performance far beyond expectations, which is why they are also known as “dust eliminators.”
The dry‑mist dust suppression system atomizes fine water droplets into mist particles ranging from 1 to 10 microns. Upon contact with dust-laden air, these mist particles capture inhalable particulate matter smaller than 5 microns, causing it to coalesce into larger agglomerates that settle under gravity, thereby achieving effective dust control. The purification efficiency can reach up to 95%. Moreover, this system not only delivers robust dust reduction but also avoids secondary pollution, with operating costs amounting to just one‑tenth of those for conventional dust‑removal equipment.
This device features low water consumption, increases material moisture by 0.02%–0.05% by weight, and incurs no calorific value loss in the material (coal). It operates under fully automatic control, requires minimal capital investment, and entails low operating and maintenance costs.
