Acoustic horn for dry dust removal and evaporation cooler dust cleaning

Main locations and causes of dust accumulation

Evaporative cooler (EC) inner wall and "banana bend" area

Improper control of water spray volume leads to low flue gas temperature, resulting in condensation water and causing dust to become damp and agglomerated.

Temperature control lag, water spray overshoot during the blowing stage, causing local scaling




Electric dust collector (EP) inlet flue (such as 120 ° elbow, climbing section)

Uneven distribution of local smoke velocity and deposition of large particulate dust.

After long-term operation, the ash layer hardens and needs to be cleaned regularly or equipped with nitrogen blowing




Ash conveying system (bin pump, ash conveying pipe, cylinder inlet branch pipe)

Ash content is damp and has strong viscosity (such as being more prone to agglomeration when high zinc oxide content is present).

Long ash conveying cycle or insufficient pneumatic ash conveying pressure, resulting in blockage




Inlet of dry dust removal box for blast furnace gas

The entrance of the abandoned gas pipeline network is prone to dust accumulation due to changes in flow state, and needs to be cleaned online

In some industrial scenarios, such as cement production, the shrinkage of the decomposition furnace and the smoke chamber are prone to skin formation, which affects the production process. In this case, a sonic horn can be used to clean the skin formation

advantage

• Non contact cleaningThere is no need for manual direct contact with the skin area for cleaning, which avoids the danger and difficulty of manual cleaning and reduces equipment wear and tear.

• High Efficiency and Energy SavingCan quickly and effectively remove crusts, compared to traditional manual tapping or other cleaning methods, can greatly improve cleaning efficiency, save time and labor costs, and consume relatively less energy.

• Uniform cleaningSound waves can uniformly act on the surface of the crust, avoiding situations where local cleaning is not sufficient, ensuring effective cleaning of the crust throughout the entire constricted area.

Reasonable installation location: It is necessary to choose a suitable installation point based on the specific structure of the constriction and the common location of the crust, to ensure that sound waves can effectively propagate to the crust area. Generally, it is installed on the outer wall of the pipeline or the wall of the smoke chamber near the constriction.
