[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0035] like Figures 1-10 As shown, this utility model discloses an integrated dust collector structure, such as a multi-compartment dust collector structure for high-temperature flue gas desulfurization and denitrification in the environmental protection field (under high temperature conditions of 200-400℃). Specifically, the dust collector structure includes a fixed support 4 and a dust collector shell 3 located on the fixed support 4; the dust collector shell 3 is internally divided into a flue structure and compartment structures (compartment structure one and compartment structure two) located on both sides of the flue structure, and each compartment structure is divided into multiple compartments by a compartment partition 1; the flue structure includes a flue and an inlet / outlet flue partition 2 inclinedly arranged in the flue, the flue is surrounded by an upper flue sealing plate 2.6, a lower flue sealing plate 2.7 and side walls 2.5 of the compartment structures on both sides, and the inlet / outlet flue partition 2 divides the flue into a lower inlet flue. The dust collector includes an inlet and outlet flue located above the flue. The inlet and outlet flue partition 2 is composed of multiple partition segments 2.1 connected sequentially, with adjacent partition segments 2.1 connected by a gap fit structure (i.e., the flue utilizes the side walls 2.5 of the two chamber shells as part of the flue, and then adds an upper flue sealing plate 2.6 and a lower flue sealing plate 2.7, which are welded to the side walls 2.5 of the chamber structure to form a high-temperature flue gas channel. The inlet and outlet flue partition 2 isolates the flue gas channel into two channels, one inlet and one outlet. The inlet and outlet flue partition 2 is designed to be composed of multiple partition segments 2.1 connected sequentially by a gap fit structure to ensure that the flue gas duct will not shift or be squeezed under thermal expansion). This dust collector structure has a high degree of integration, saves materials, and is easy to construct because it does not require a flue gas channel independent of the dust collector shell 3.

[0036] The aforementioned clearance fit structure includes a fixed plate 2.4, a pressure block 2.3, and a bottom support plate (L-shaped plate). The fixed plate 2.4 is disposed between adjacent partition sections 2.1, and there are gaps between the fixed plate 2.4 and the partition sections 2.1 located on both sides of the fixed plate 2.4. Both sides of the fixed plate 2.4 are connected to the side walls 2.5 of the compartment structure on both sides, and pressure blocks 2.3 and bottom support plates are correspondingly provided on both sides of the fixed plate 2.4, with the pressure blocks 2.3 located above the partition sections 2.1 and the bottom support plates located below the partition sections 2.1; thereby making the partition... Segment 2.1 can slide within the gap between the pressure block 2.3 and the bottom support plate; each partition segment is provided with a peripheral plate 2.2, and the partition segment 2.1 overlaps and is fully welded to the peripheral plate 2.2 located above the partition segment 2.1; both ends of the pressure block 2.3 and both ends of the fixing plate 2.4 are fully welded to the side walls 2.5 of the compartment structure on both sides; the pressure block 2.3 is fully welded to the fixing plate 2.4, and the pressure block 2.3 is made of square tubing; the pressure block 2.3 is used to press down the partition segment 2.1 to ensure that the partition segment 2.1 can slide under thermal expansion.

[0037] Specifically, the dust collector housing 3 is connected to the fixed support 4 using a sliding groove structure 5 (i.e., to cope with thermal expansion, the dust collector housing 3 and the fixed support 4 are no longer welded but instead use a sliding groove structure 5, allowing the dust collector housing 3 to expand and slide in the guide groove). Specifically, the sliding groove structure 5 includes a housing flange 5.1 and an inverted L-shaped pressure plate 5.2; the housing flange 5.1 is fixed to the outside of the dust collector housing 3 (the housing flange 5.1 is fully welded to the dust collector housing 3), and the inverted L-shaped pressure plate... Plate 5.2 is fixed on the fixed bracket 4 (the inverted L-shaped pressure plate 5.2 is fully welded to the fixed bracket 4), and the housing flange 5.1 is set inside the inverted L-shaped pressure plate 5.2 and can slide along the inverted L-shaped pressure plate 5.2 (that is, the inverted L-shaped pressure plate 5.2 and the housing flange 5.1 are clearance-fitted), thereby restricting the sliding direction of the dust collector housing 3, ensuring that the dust collector housing 3 as a whole can slide freely under thermal expansion and does not interfere with the displacement of the fixed bracket 4; thus preventing the various units from being squeezed and deformed or tipping over due to thermal expansion.

[0038] In an embodiment of this utility model, the aforementioned compartment partition 1 includes a welded frame cavity 1.1 and aluminum carbonate fiber cotton 1.2 filled within the welded frame cavity 1.1. The welded frame cavity 1.1 is made of shaped steel, specifically channel steel, and the aluminum carbonate fiber cotton 1.2 is firmly filled within the welded frame cavity 1.1. Specifically, the compartment partition 1 is manufactured by first welding shaped steel into a cavity of a certain thickness, and then filling the cavity with high-temperature resistant aluminum carbonate fiber cotton 1.2 to insulate against heat conduction. When personnel are performing maintenance in a compartment, the temperature can be controlled within an acceptable range.

[0039] In an embodiment of this utility model, the dust collector housing 3 is welded together from plates with reinforcing ribs; specifically, the dust collector housing 3 includes a first chamber structure and a second chamber structure on both sides of the flue structure. Figure 9 3.1 is the front enclosure panel of the first compartment structure; 3.2 is the end enclosure panel of the first compartment structure; 3.3 is the end enclosure panel of the second compartment structure; 3.4 is the rear enclosure panel of the second compartment structure, and each enclosure panel is stamped with reinforcing ribs to increase the rigidity of the panel.

[0040] This utility model relates to the design of a desulfurization and denitrification equipment for treating high-temperature flue gas. The dust collector structure is planned as a very large dust collector shell, with separate compartments isolated within the shell. Adjacent compartments are insulated from each other using high-temperature resistant materials. The high-temperature flue gas ducts are isolated using the space between the compartment shells. The connection between the dust collector shell and the fixed support uses a sliding groove structure to ensure that the various units do not conflict during thermal expansion. The inlet and outlet flue baffles are designed with a gap fit structure to absorb thermal expansion deformation.

[0041] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solution of the present invention, or modify them into equivalent embodiments with equivalent changes, which does not affect the essential content of the present invention.
