The filter cleaning system includes a first filter, a first-stage cleaning unit, a sensing unit, a control unit, and a second-stage cleaning unit. The first-stage cleaning unit includes at least one of an adsorption assembly, a washing assembly, or a brush assembly. The second-stage cleaning unit includes a motor and a mandrel assembly that includes a second filter, and is configured to replace at least one part of the first filter with a part of the second filter.

An air intake screen debris cleaning system may include an intake screen through which air is drawn in a first direction for cooling, a reverse airflow generation system to create a reverse airflow in a second direction opposite the first direction to clear debris from the intake screen, a sensor to sense debris that is collected on the intake screen and a controller to activate the reverse airflow generation system based upon signals from the sensor. In one implementation, the sensor comprises an emitter to emit a sensor beam that extends along a face of the air intake screen and which does not intersect or pass through the air intake screen prior to being sensed.

An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.

The disclosure relates to a filter cartridge for removing impurities from a stream of raw gas to be filtered, including a cylindrical filter element which is made of a filter material and in which a filter insert is inserted, an interior space being formed between the filter element and the filter insert, the filter material being designed to be cleaned when a stream of compressed air is applied against a flow direction of the stream of raw gas, a cap designed as a flow guiding device being provided for guiding the stream of compressed air, wherein the cap is arranged such that it projects beyond an axial length of the filter element in the axial direction. The disclosure further concerns a filter system for removing impurities from a stream of raw gas to be filtered. In addition, the disclosure relates to a method for cleaning such a filter cartridge.

A membrane method processing system and process for a high-concentration salt-containing organic waste liquid incineration exhaust gas is described. The system consists essentially of a waste liquid incinerator (I), a gas-solid separator (II), a heat exchanger (III), an air blower (IV), an anti-caking agent storage tank (V), a membrane method dust cleaner (VI), an induced draft fan (VII), a check valve (VIII), and a desulfurization tower (IX). The present invention introduces the dust collecting membrane into the tail gas treatment system and utilizes the small pore size and high porosity of the dust collecting membrane to prevent inorganic salt particles from entering the internal of the filter material and agglomerating there. When the humidity of the gas entering the dust collector increases during the dust removing process, the anti-caking agent is also introduced into the tail gas treatment system to change the surface structure of the inorganic salt crystal to prevent the crystal from agglomeration.

A dust collecting treatment apparatus is connected to a dry type polishing apparatus, sucks dust-containing air from the dry type polishing apparatus, and separates the dust and the air from each other. The apparatus includes a cylindrical main body connected to the dry type polishing apparatus; a suction box disposed on an upper plate of the cylindrical main body, a suction source connected to the suction box through a ventilating duct, a filter unit that includes a flange section supported on the upper plate of the cylindrical main body, a pipe formed integrally with the flange section and formed of a plurality of minute holes, and a filter formed of a water-soluble material and externally fitted to the pipe in a detachable manner. The filter is disposed inside the cylindrical main body. A water jet nozzle is disposed inside the suction box and jets water into the filter unit.

The air filter cleaning device provides a tool for efficiently cleaning an air filter. the air filter cleaning device includes an elongated coil extending between a first end and a second end. The coil includes a surface that defines a hollow interior extending between first end and second end such that the coil is configured to be tubular. the elongated straight portion is connected with the actuator via the swivel joint. The coil is placed into the cavity of the air filter. The actuator is actuated, thereby causing air to enter the first end, flow through the interior and exit the opening. The pressure of the air exiting the opening causes the coil to rotate relative to the air filter. As the coil rotates, the pressure of the air pushes dust and/or debris from the porous material of the air filter.

An apparatus and a method are provided for an air filter cleaning wand for flushing contaminants from an intake air filter of an automobile engine. The air filter cleaning wand comprises a proximal flange, a conduit, and a distal end portion. The proximal flange is configured to receive a nozzle of a water hose. An interior of the conduit is in fluid communication with the proximal flange. The distal end portion comprises a plurality of longitudinally aligned vents in fluid communication with the interior of the conduit. Upon passing water through the water hose and into the conduit, pressurized water streams exit the vents along the distal end portion so as to flush contaminants from the air filter. The air filter cleaning wand advantageously is comprised of a material which is sufficiently durable and temperature resistant to retain its configuration during operation when coupled to pressurized water sources.

The filtering apparatus includes: a casing having an inlet for a fluid from the outside and an outlet for the fluid having filtered therein; filter elements having opposite-end openings, provided in the casing, and each filtering the fluid by allowing the fluid to flow therethrough in inside-to-outside directions; backwashing pipes sequentially connected to the opposite-end openings at different timings between the opposite-end openings of each filter element so as to backwash the filter element by allowing the fluid to flow therethrough in outside-in directions; removers each axially moved in the corresponding filter element by the filtration or backwashing flow, while sliding in contact with the inner periphery of the filter element so as to remove trapped objects; and a backwashing fluid drain pipe coupled to the discharge side of the backwashing pipes and allowing the trapped objects removed by each remover to be discharged to the outside.
