A filter screen component, a base assembly, a clothes dryer, and a washing and drying integrated machine. The filter screen component comprises a motor and a filter screen part; the filter screen part comprises an annular filter screen body having holes; one end of the filter screen body is connected to a rotary shaft of the motor, and the other end is provided with an opening. The filter screen component, the base assembly, the clothes dryer, and the washing and drying integrated machine can not only effectively filter impurities such as soft flocks in an air flow, but also require, when cleaning the impurities such as soft flocks, no additional cleaning parts or manual cleaning; the cleaning is thoroughly completed.

A an example replaceable ultraviolet (UV) lamp cartridge includes: a tamper-proof UV energy absorbing shell containing one or more UV radiation emitting devices; an air inlet disposed at a first end of the tamper-proof UV energy absorbing shell; an air outlet disposed at a second end of the tamper-proof UV energy absorbing shell; and a self-aligning connector for receiving external voltage to be supplied to the UV energy emitting devices.

An example air purification system comprises: an air guiding funnel; a particle absorbing filter disposed at an intake side of the air guiding funnel; a tangential fan disposed at an outlet side of the air guiding funnel; and an ultra-violet (UV) energy absorbing shell mechanically coupled to an discharge side of the tangential fan.

An exhaust purification system has a centrifuge filter, a first fan device, a second fan device, a pump, and an ozone generator. The centrifuge filter has a container having a waste gas treating area and a wastewater treating area. The first fan device communicates with and draws gas into the waste gas treating area. The second fan device communicates with and draws the gas out of the waste gas treating area. The pump communicates with and draws wastewater from the wastewater treating area. The ozone generator communicates with the pump and introduces ozone into the wastewater inside the pump. A part of the ozone dissolved in the wastewater is released to the waste gas treating area to react with the gas, and the other part of the ozone dissolved in the wastewater reacts with the wastewater.

A filter assembly for a gas turbine system includes a filter element configured to remove entrained particles from air which passes through the filter element in a first direction toward a central air passageway. A motion generator arranged to rotate the filter element about a longitudinal axis extending in an airflow direction of the air passageway to cause particles accumulated on the filter element to fall downwardly away from the filter element due to gravity.
