Description

Technical Field

[0001] The utility model relates to the technical field related to waste gas purification, in particular to a flue gas multi-layer filtering structure. Background Art

[0002] Waste gas purification mainly refers to the work of treating industrial waste gases such as dust particles, flue gas, odorous gases, and toxic and harmful gases generated in industrial sites. Waste gases emitted by industrial production often have harmful effects on the environment and human health. Purification measures should be taken before they are discharged into the atmosphere to make them meet the requirements of waste gas emission standards. The purification of waste gas inevitably requires the use of filtering devices. In order to better purify the waste gas, a flue gas multi-layer filter structure is particularly needed.

[0003] However, most of the existing filtering devices do not have the effect of multiple filtration, and when operating for a long time, a large amount of dust will adhere to the surface of the filtering device, which will inevitably affect the work efficiency when handling the dust. Utility Model Content

[0004] The purpose of the present utility model is to provide a multi-layer flue gas filtering structure to solve the problem that most of the existing filtering devices proposed in the above background technology do not have the effect of multiple filtration, and when operating for a long time, a large amount of dust will adhere to the surface of the filtering device, which will inevitably affect the work efficiency when handling the dust.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a multi-layer smoke filtering structure, comprising a cyclone tower, a bottom shell mounted on one side surface of the cyclone tower, a filtering mechanism disposed on one side surface of the bottom shell, and a sealing mechanism disposed on one side surface of the bottom shell;

[0006] The filtering mechanism includes a mounting hole, a bracket, a filter shell, a cover plate and an exhaust pipe. A mounting hole is opened on one side surface of the bottom shell, the inner surface of the mounting hole is fixedly connected to the bracket, the outer surface of the bracket is sleeved with the filter shell, a cover plate is installed on one side surface of the bottom shell, and the exhaust pipe is installed on one side surface of the cover plate.

[0007] Preferably, the mounting holes are opened symmetrically with respect to the central axis of the bottom shell, and the outer wall size of the cover plate matches the outer wall size of the bottom shell.

[0008] Preferably, the outer wall size of the filter housing matches the inner wall size of the mounting hole, and the filter housings are provided in multiple groups.

[0009] Preferably, the inner wall size of the filter housing matches the outer wall size of the bracket, and the bracket is provided in multiple groups.

[0010] Preferably, the sealing mechanism includes a collecting box, a discharge pipe, a mounting groove, a threaded groove, a sealing ring, a fixing ring and a valve. The collecting box is welded to the lower surface of the bottom shell, and a discharge pipe is installed on one side surface of the collecting box. The inner surface of the discharge pipe is provided with a mounting groove, and the inner surface of the mounting groove is provided with a threaded groove. The inner surface of the mounting groove is fixedly connected to a sealing ring, the inner surface of the threaded groove is fixedly connected to a fixing ring, and one end surface of the discharge pipe is fixedly connected to a valve.

[0011] Preferably, the thread groove is threadedly connected to the fixing ring, and the outer wall size of the valve matches the inner wall size of the sealing ring.

[0012] Preferably, the outer wall size of the sealing ring matches the inner wall size of the installation groove, and the outer wall size of the fixing ring matches the inner wall size of the threaded groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the multi-layer flue gas filtering structure is provided with mounting holes, brackets, filter shells, cover plates and exhaust pipes. When the flue gas is filtered, the larger particles contained in the flue gas will fall to the bottom of the cyclone tower when the flue gas passes through the cyclone tower. The flue gas after preliminary treatment will enter the bottom shell through the connecting pipe. At this time, the smaller particles in the flue gas will adhere to the surface of the filter shell, and the flue gas that meets the emission standards after treatment will be discharged through the exhaust pipe. When the flue gas is filtered, the particles attached to the outer surface of the filter shell are vibrated and fall off into the collection box. When a certain amount is accumulated, the valve is opened. At this time, the particles accumulated in the collection box will be discharged from the collection box through the discharge pipe. When the particle discharge is completed, the valve is closed. At this time, the valve will squeeze the sealing ring to seal it. This solves the problem of the above-mentioned existing filtering devices. Most filtering devices do not have the effect of multiple filtration, and when operating for a long time, a large amount of dust will adhere to the surface of the filter device, which will inevitably affect the work efficiency when handling dust.
