Installing and debugging water washing and dust removal equipment for a Malaysian client.

Installing and debugging water washing and dust removal equipment for a Malaysian client. The client has been in the fertilizer industry for many years and has cooperated with our company multiple times, exploring and experimenting with new technologies for organic fertilizer production, and investing in new equipment to provide technical support for the company’s development. This time, in order to improve production efficiency, new water washing and dust removal equipment has been installed

Water-washing dust removal equipment (wet dust collectors) are widely used in dust control scenarios across multiple industries, particularly in complex working conditions involving high temperatures, flammable and explosive gases, corrosive gases, and viscous dust. This is due to their core advantages, such as explosion-proofing, high temperature resistance, the ability to simultaneously treat dust and corrosive gaseous pollutants, and the absence of secondary dust emission. The following are specific application scenarios and descriptions:
1. Application scenarios in key industries
Metallurgy / Foundry Industry
Typical operating conditions: dust removal of blast furnace flue gas, dust control of electric furnaces, sand treatment of castings, purification of high-temperature flue gas from metal smelting
Adaptation reason: It can directly handle high-temperature gas at 300-500℃, combining dust removal and cooling functions; the aqueous medium prevents electrostatic accumulation and can safely handle flammable and explosive materials such as aluminum and magnesium alloy dust; it can also simultaneously remove sulfides and nitrogen oxides from flue gas.
Recommended equipment type: combination of Venturi dust collector and water film dust collector, or impact dust collector
Chemical / Pharmaceutical Industry
Typical operating conditions: dust control in chemical raw material crushing, exhaust gas purification in pesticide/fertilizer production, acid and alkali mist treatment, and dust removal in the processing of flammable and explosive powders (such as coal powder and resin powder)
Adaptation reasons: It can efficiently capture fine particulate dust while absorbing acidic gaseous pollutants such as HCl and SO₂; it has excellent explosion-proof performance, avoiding the risk of dust explosion; it is made of corrosion-resistant materials (glass fiber reinforced plastic, PP) that can withstand corrosive media.
Recommended equipment types: self-excited dust collector, corrosion-resistant spray tower
Mining / Quarrying Industry
Typical working conditions: dust control during ore crushing, screening, and conveying processes, as well as spray dust removal in the raw material storage yard of a stone material factory
Adaptation reasons: It can handle high inlet dust concentration (up to 100g/m³) dust, with simple structure and low failure rate, suitable for harsh operating environments in mines; it can effectively suppress the diffusion of coarse particle dust and reduce dust pollution in the plant area.
Recommended equipment types: Impulse dust collector, simple spray tower
Power/boiler industry
Typical operating conditions: flue gas dust removal and desulfurization for coal-fired boilers and biomass boilers, and tail gas purification for waste incinerators
Adaptation reasons: With high temperature and high humidity resistance, it can directly handle high-temperature flue gas discharged from boilers; by optimizing the liquid-to-gas ratio, it achieves integrated dust removal and desulfurization treatment, reducing equipment investment costs.
Recommended equipment types: Venturi desulfurization and dust removal integrated machine, horizontal water film dust collector
Building materials / cement industry
Typical working conditions: cement grinding, rotary kiln dust control, ceramic raw material crushing and dust removal, gypsum board production dust purification
Adaptation reason: For viscous dust such as cement and gypsum, it can avoid the problem of filter bag blockage in dry dust collectors (such as bag filters); after the dust is adsorbed by the water film, there is no secondary dust emission, ensuring cleanliness in the workshop.
Recommended equipment types: water rotary tower, vertical water film dust collector
Organic fertilizer / feed processing industry
Typical working conditions: dust control during the crushing and screening of organic fertilizer after fermentation, and dust control during the mixing of feed raw materials
Adaptation reason: Organic fertilizer dust often contains viscous organic matter. Water washing dust removal can effectively capture dust and dissolve some odorous gases (such as ammonia); The equipment operates without dust leakage and meets environmental protection requirements.
Recommended equipment types: spray tower, small self-excited dust collector
Wood processing / furniture industry
Typical working conditions: wood sanding, cutting dust control, paint mist treatment in spray painting workshop
Adaptation reason: It can simultaneously handle wood dust and a small amount of VOCs (volatile organic compounds), and the purification effect is better when paired with an activated carbon adsorption layer; the aqueous medium is explosion-proof, avoiding the risk of wood dust explosion.
Recommended equipment type: combination of spray tower and activated carbon adsorption box
II. Special Applications for Special Operating Conditions
Flammable and explosive dust conditions
In processes such as the processing of aluminum powder, magnesium powder, coal powder, and flour, water serves as an insulating medium that can conduct away static electricity, effectively eliminating dust explosions at their source. It is the preferred dust removal solution for such scenarios.
High-temperature gas pretreatment condition
For high-temperature flue gases from processes such as smelting, forging, and boiler operations, there is no need to install additional cooling devices. Water washing and dust removal can not only capture the dust but also reduce the gas temperature to a suitable range, facilitating subsequent advanced treatment.
Working conditions involving corrosive gases
For processes such as chemical acid-base production and electroplating acid pickling exhaust gas, the use of water washing equipment made of corrosion-resistant materials can simultaneously remove dust and acidic/alkaline gaseous pollutants, achieving “multi-purpose functionality in one machine”.
