The present invention relates to a cage for a tubular, extended surface filter bag that increases the internal volume of the bag and provides reduced resistance to the gas flow path through the cage. The cage includes a plurality of vertical cage wires that extend longitudinally, and has at least one horizontal cage support shaped to support the vertical cage wires in a tubular formation. The cage supports are in the form of pressed metal straps having a wide body extending between two thin edges.

In the description and drawings a fiberglass product is disclosed. The fiberglass product may have one or more fiber curl layers. The fiber curl layers may have a plurality of generally sinusoidal fiber bundles therein.

A filter leakage monitoring device of a particle separator includes a plurality of sampling pipes each of which has a visible part through which an inside of the sampling pipe can be visually recognized, a suction port of each of which corresponds to each of a plurality of filters disposed in a particle-containing air chamber into which air containing particles are introduced, the suction port of each of which is positioned near an air intake port that sucks air that has passed through each of the filters into a clean air chamber, and a vacuum pump that sucks air through each of the sampling pipes.

Provided are system and method thereof for desulfurization and dedusting of flue gas from a coke oven. The system for desulfurization and dedusting of flue gas from a coke oven includes a heat exchanger, a desulfurization reaction unit, a dedusting unit, and a blower; the heat exchanger includes a raw flue gas duct and a clean flue gas duct; the raw flue gas duct, the desulfurization reaction unit, and the dedusting unit are coupled in sequence, a clean flue gas outlet of the dedusting unit communicates with an inlet of the clean flue gas duct, and an outlet of the clean flue gas duct is coupled to the blower. The raw flue gas is heated in the heat exchanger by using temperature difference between clean flue gas and the raw flue gas, and then the raw flue gas is delivered into the desulfurization reaction unit for a desulfurization reaction.

Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. Air filter systems, filter bag assemblies, filter bags and corresponding methods are described herein. The filter bag assemblies include a flange assembly, a cage attached to the flange assembly, and a filter bag installed over the cage with an opening at the flange assembly. When installed in the dirty air chamber of the air filter system, a seal between the flange assembly and the tubesheet defining the dirty air chamber is provided by applying a seal force on the end of the filter bag assembly located proximate the access panel on the side of the dirty air chamber opposite the tubesheet. That seal force is transmitted to the flange assembly through the cage. The tubular filter bags may be in the form of triangular bags and/or may include bag support connectors at the closed end of the bag.

A powder collector including a box including a first opening configured to pass powder therethrough, a bottom portion disposed so as to oppose the first opening, and a side portion that intersects the first opening and the bottom portion, the box being configured to install a bag provided so as to be in communication with the first opening, a second opening provided in the box, the second opening being configured to suction a gas inside the box, a plurality of frames disposed in at least either one of the bottom portion and the side portion, and a flow portion configured to flow the gas therethrough. In the powder collector, the flow portion is a gap formed between a frame among the plurality of frames and another frame among the plurality of frames.

A filter element includes: a frame having a peripheral elastomer body in which a reinforcement element is embedded; and a filter pocket. The frame is connected to an opening in the filter pocket with a connection established integrally by the elastomer body. In an embodiment, the elastomer body is molded on the filter pocket.

The system for desulfurization and dedusting of flue gas from a coke oven includes a heat exchanger, a desulfurization reaction unit, a dedusting unit, and a blower; the heat exchanger includes a raw flue gas duct and a clean flue gas duct; the raw flue gas duct, the desulfurization reaction unit, and the dedusting unit are coupled in sequence, a clean flue gas outlet of the dedusting unit communicates with an inlet of the clean flue gas duct, and an outlet of the clean flue gas duct is coupled to the blower. The raw flue gas is heated in the heat exchanger by using temperature difference between clean flue gas and the raw flue gas, and then the raw flue gas is delivered into the desulfurization reaction unit for a desulfurization reaction.

A filter support for a filter is adjustable to modify the size and/or shape of the filter. The filter support may include one or more wedges engaging a wall of the filter, and a connector connecting the one or more wedges to one another. The connector allows selective adjustment of the filter support.
