Description

Technical Field

[0001] This utility model relates to the field of dust collectors, and in particular to a dual-chamber dust collector structure. Background Technology

[0002] The dust collector mainly consists of an ash hopper and a filter bag box. Coarser dust particles settle downwards into the ash hopper due to gravity, while the filter bags adsorb smaller dust particles. Over time, the dust adsorbed on the outer wall of the filter bags accumulates, gradually increasing the dust collector's resistance and reducing the amount of gas it can process. To keep the dust collector in an effective working state and maintain pressure loss within a certain range, the dust-laden flue gas needs to be evenly distributed in each chamber, ensuring that the amount of dust-laden flue gas filtered by the filter bags in each chamber is the same. Currently, there are two air inlet methods for baghouse dust collectors: one is through the ash hopper with openings, and the other is through side air inlet with an air inlet channel inside the main body of the casing. Both methods allow flue gas to enter the dust collector body. However, in existing project applications, it has been found that when using these two air inlet methods for larger air volume dust collectors, the flue gas distribution in each chamber becomes uneven, resulting in inconsistent dust removal and incomplete dust removal. Furthermore, the dust collector cover structure is inconvenient to install on site. Utility Model Content

[0003] The purpose of this invention is to provide a dual-chamber dust collector structure that solves the problems of inconvenient on-site installation of the dust collector cylinder structure and unstable connection of various components, resulting in a short service life.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dual-cavity dust collector structure, including a dust collector cylinder structure, a collection hopper structure disposed at the lower part of the dust collector cylinder structure, and an interface top cover structure at the upper part of the dust collector cylinder structure. The dust collector cylinder structure is a dual-cavity dust collector cylinder structure including a left cylinder and a right cylinder. The interface top cover structure includes a left top cover structure and a right top cover structure that are connected to the left cylinder and the right cylinder. The lower parts of the left cylinder and the right cylinder are fixed to the upper part of a connecting cavity. The collection hopper structure includes a left-end conical hopper structure and a right-end conical hopper structure disposed at the lower part of the connecting cavity. The left cylinder and the right cylinder are a composite cylinder structure.

[0005] The left top cover structure includes a left butterfly head and a left top pipe structure located on top of the left butterfly head. The right top cover structure includes a right butterfly head and a right top pipe structure located on top of the right butterfly head. A circumferential welded reinforcing section is provided between the left butterfly head and the left cylinder and between the right butterfly head and the right cylinder, and an internal reinforcing weld point and an external reinforcing weld point are provided in the circumferential welded reinforcing section.

[0006] A side inlet pipe is provided at the connection between the left butterfly head and the left cylinder, and a side outlet pipe is provided at the connection between the right butterfly head and the right cylinder. An angle weld reinforcement point is provided at the corner joint between the side inlet pipe and the left cylinder.

[0007] The external part of the connecting cavity is provided with multiple sets of base pieces.

[0008] The bottom ends of the left-end conical hopper structure and the right-end conical hopper structure are each provided with a bottom interface.

[0009] The beneficial effects of this utility model are as follows: The dust collector modification scheme involves fabricating and welding a new end cap on the existing dust collector's top cover, which is manufactured on-site and achieves the original equipment's performance. Simultaneously, the dual-chamber cylinders are connected as one unit through a connecting chamber; this buffers the wind force, ensuring consistent wind pressure in the vertical sections of the two cylinders, thereby maintaining pressure balance on both sides and ensuring uniform wind pressure entering the air chamber.
