Description

Technical Field

[0001] This utility model relates to the field of flue gas dust removal technology, specifically an integrated cascade filtration wet high-efficiency dust collector. Background Technology

[0002] A Chinese utility model patent with application number 201720329530.X discloses an integrated cascade filtration wet high-efficiency dust collector, which improves the filtration and dust removal effect by setting up a three-set water spray system structure to achieve cascade filtration. However, in the above structure, the wastewater after spraying by the three sets of water spray systems is placed at the bottom of the dust collector. Since the cascade filtration results in different wastewater concentrations, there are problems of waste and low efficiency in the unified treatment and utilization of wastewater. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing an integrated, multi-stage filtration wet high-efficiency dust collector that ensures dust removal efficiency while facilitating separate wastewater treatment and collection at different spray levels.

[0004] To achieve the above objectives, this utility model of an integrated cascade filtration wet high-efficiency dust collector adopts the following technical solution: An integrated cascade wet high-efficiency dust collector includes a dust collector tower. The dust collector tower has a flue gas inlet at the bottom and a flue gas outlet at the top. The dust collector tower contains a first filtration zone and a second filtration zone, arranged vertically. The first filtration zone is located below the second filtration zone. The first filtration zone includes a first spray structure, with a filter bag structure above it. The second filtration zone includes a fixed plate structure, located above the filter bag structure. A second spray structure is located above the fixed plate structure, and a dewatering structure is located above the second spray structure. The fixed plate structure is used to receive wastewater from the second spray structure and to supply flue gas rising from the first filtration zone to the second filtration zone. The dust collector tower has a first water outlet at its lower end and a second water outlet on its side wall, at the same height as the upper plate.

[0005] A further improvement of this utility model of an integrated stepped wet high-efficiency dust collector is that the fixed plate structure includes an upper plate with several vertically penetrating fixed holes, a lower plate below the upper plate with several vertically penetrating second fixed holes, a through pipe extending upward from the second fixed hole, the through pipe passing through the fixed hole, the outer wall of the through pipe abutting against the hole wall of the fixed hole, and a conical plate above the through pipe with a gap between the conical plate and the upper end face of the through pipe.

[0006] A further improvement of this utility model of an integrated stepped wet high-efficiency dust collector is that the conical plate is connected to the insertion tube by a connecting rod, and at least two sets of connecting rods are provided, which are distributed at intervals, and the insertion tube is inserted into the through tube.

[0007] A further improvement of this utility model of an integrated cascade wet high-efficiency dust collector is that an extension plate is provided on the outer periphery of the lower plate, the extension plate is connected to the dust collector tower body, and the upper plate and the lower plate are connected by bolt and nut connectors.

[0008] A further improvement of this utility model of an integrated stepped wet high-efficiency dust collector is that a sealing structure is provided at the fixing hole, the outer periphery of the upper plate, and the outer periphery of the lower plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a two-stage filtration structure with separate design, allowing the filtered wastewater from the two stages to be collected separately, thus improving the efficiency of classified collection and treatment. At the same time, the fixed plate structure is easy to disassemble, facilitating subsequent disassembly and cleaning. Attached Figure Description

A through-tube 7 is positioned upwards at each of the second through-holes, passing through the fixing holes. The outer wall of the through-tube abuts against the wall of the fixing hole. A tapered plate 8 is positioned above the through-tube, with a gap between the tapered plate and the upper surface of the through-tube. The through-tube and the lower plate can be integrally formed.

[0017] The conical plate is connected to the insertion tube via connecting rod 9. There are at least two sets of connecting rods, spaced apart, and the insertion tube is inserted into the through tube. Multiple conical plates in the same row or column can be connected by a fixing rod, facilitating the insertion of multiple conical plates into multiple through tubes.
