About used scrubber

Types of used scrubbers

Used scrubber systems are industrial equipment used to remove particulate matter and gases from exhaust streams. They are typically used in industries such as mining, chemical manufacturing, and construction. There are several types of used scrubbers, including:

  • Wet scrubbers

    These are the most common and straightforward types of scrubbers. Wet scrubbers eliminate pollutants from gas streams by forcing the gas through a liquid. The pollutants are trapped in the liquid and are separated from the gas. Wet scrubbers can be applied to different industries and can eliminate solid, liquid, and gaseous pollutants. Different liquids can be used in wet scrubbers, such as water, acids, or alkaline solutions, based on the pollutants being removed. They work well in applications with high temperatures and pressures.

  • Dry scrubbers

    As the name suggests, dry scrubbers do not utilize liquids in the process. Instead, dry scrubbers use solid chemicals, such as absorbents, to capture and neutralize pollutants from gas streams. They are commonly employed to control acid gas emissions, like sulfur dioxide and hydrogen chloride. Dry scrubbers are compact and require less water compared to wet scrubbers, making them suitable for areas with limited water supply or where water usage needs to be minimized.

  • Fabric scrubbers

    Fabric scrubbers are a type of used scrubber that utilizes fabric filter bags to capture and remove particulate matter from gases. The gas passes through the fabric filter bags, and the dust and particles are trapped inside the bags. Periodic cleaning of the bags is required to remove the accumulated dust. Fabric scrubbers are effective for various industries and can capture fine particulates, improving air quality and compliance with environmental regulations.

  • Electrostatic scrubbers

    Electrostatic scrubbers use electrostatic forces to separate particulates from gas streams. They consist of ionization electrodes that generate negative and positive ions in the gas stream. The charged particles are attracted to collection plates or electrodes, where they are gathered and removed from the gas. Electrostatic scrubbers are efficient in controlling fine particulate emissions and can handle large gas volumes, making them suitable for power plants and waste incineration facilities.

  • Cyclone scrubbers

    Cyclone scrubbers combine the principles of cyclones and scrubbers to achieve efficient particle separation. The gas is swirled inside the cyclone scrubber, generating centrifugal forces that throw larger particles against the cyclone's wall. The particles are then collected and removed. Cyclone scrubbers are effective for controlling particulate emissions and are often used as pre-cleaners for other scrubber systems.

Design of used scrubbers

Used scrubbers are industrial equipment designed to reduce air pollution caused by scrubbers. Its design concept is to remove harmful particles and sulfur dioxide gas from industrial exhaust air to protect the environment and human health. Typically, a scrubber consists of a scrubber tower, a spraying system, a drainage system, a gas outlet, and a supporting framework. The scrubber tower is the core component of the equipment, usually shaped like a vertical cylinder or rectangular prism, where the gas is treated. In the tower, a liquid is sprayed onto the gas through the spraying system; the liquid can be water or other special washing agents.

Used scrubbers are usually designed with a modular approach, which can be applied flexibly according to the actual needs of different industries and the characteristics of the exhaust gas. In addition, used scrubbers are designed with considerations for safety and reliability. Sufficient strength and stability of the equipment are ensured to withstand the pressure and weight of the liquid. Safety devices are equipped, such as pressure relief devices and liquid level alarms, to prevent accidents. The durability and reliability of used scrubbers are ensured by using corrosion-resistant materials and wear-resistant components, thereby extending their service life. Moreover, the noise and vibration of used scrubbers are reduced through appropriate designs and installations, ensuring their operation within the allowable range of standards and providing a comfortable working environment.
