Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal devices, in particular to a dust removal device for a flue gas pipeline. Background Art

[0002] The flue gas duct dust removal device is an interception device set up for solid dust in the flue gas. It can intercept ash, coal particles and oil droplets in the flue gas to form a physical filtration of the flue gas.

[0003] In the existing technology, dust suppression nozzles are often used to intercept flue gas in a physical sense. However, in actual use, the nozzles can only intercept part of the impurities, and the interception is insufficient. The fundamental reason is that part of the flue gas cannot come into contact with the spray, and the flue gas and water cannot be fully mixed. Utility Model Content

[0004] The present invention aims to solve the problems existing in the prior art and proposes the following technical solutions:

[0005] A flue gas duct dust removal device includes a flue gas duct main body and an air outlet installed on the flue gas duct main body. A cover is installed on the outside of the air outlet through a disassembly and assembly mechanism. The bottom end of the cover is inserted into a water tank. The side of the water tank close to the air outlet is inserted into multiple corresponding hole grooves on the side wall of the air outlet.

[0006] After the flue gas is discharged from the air outlet, the flue gas enters the water tank through the channel between the cover and the air outlet under the action of the cover, so that the flue gas is fully forced to contact with the aqueous solution in the water tank, thereby fully intercepting the impurities in the flue gas.

[0007] As a preferred embodiment of the above technical solution, the opening end of the cover is lower than the liquid level in the water tank.

[0008] This can ensure that the flue gas is directly and completely separated from the aqueous solution in the water tank, and achieve high efficiency in stripping solid impurities in the flue gas.

[0009] As a preferred embodiment of the above technical solution, the disassembly and assembly mechanism includes a plug-in rod plugged into the air outlet, and the plug-in rod is installed in the cover, and a limiting rod is plugged into the side wall of the plug-in rod, and the end of the limiting rod away from the plug-in rod passes through the outer wall of the cover and is connected to the pull plate, and the inner side wall of the pull plate is symmetrically connected with an elastic member, and the pull plate is connected to the limiting groove through the elastic member, and the limiting groove is symmetrically opened on the outer wall of the cover.

[0010] As a preferred embodiment of the above technical solution, a pull ring is installed on the side of the pull plate away from the limiting rod, and the cross-section of the pull ring is arc-shaped.

[0011] The arc-shaped structure design of the pull ring makes it easy to pull the limit rod and the pull plate.

[0012] As a preferred embodiment of the above technical solution, the pull plates are all connected with sliders, and the sliders all slide in slide rails, and the slide rails are symmetrically arranged in the limiting grooves.

[0013] Under the sliding action between the slider and the slide rail, the smoothness and efficiency when the pull ring is pulled to drive the limit rod and the pull plate to move are guaranteed.

[0014] As a preferred embodiment of the above technical solution, the inner wall of the hole in the limiting groove close to the cover for the limiting rod to slide is glued with a sealing gasket.

[0015] With the use of the sealing gasket, the air tightness of the device is guaranteed during use.

[0016] The beneficial effects of the utility model are:

[0017] In the present application, after the smoke is discharged from the air outlet, the smoke enters the water tank through the channel between the cover and the air outlet under the action of the cover, so that the smoke is fully forced to contact with the aqueous solution in the water tank, thereby fully intercepting the impurities in the smoke.

After the flue gas is discharged from the air outlet 2, under the action of the cover 3, the flue gas enters the water tank 4 through the channel between the cover 3 and the air outlet 2, so that the flue gas is fully forced to come into contact with the aqueous solution in the water tank 4, thereby fully intercepting the impurities in the flue gas.

[0024] like Figure 1 and Figure 2As shown, in the embodiment of the present invention, the flue gas duct dust removal device includes a flue gas duct main body 1 and an air outlet 2 installed on the flue gas duct main body 1; the flue gas is discharged through the air outlet 2 via the flue gas duct main body 1, which is well known to those skilled in the art and will not be elaborated in this application.

After the plugging is completed, the pull plate 7 is released, so that the limit is driven by the elastic reaction force of the elastic member 11. The rod 6 is inserted into the side wall of the plug-in rod 5 to complete the installation operation between the cover 3 and the air outlet 2; a pull ring 8 is installed on the side of the pull plate 7 away from the limit rod 6, and the cross-sectional shape of the pull ring 8 is arc-shaped; under the arc-shaped structural design of the pull ring 8, the limit rod 6 and the pull plate 7 can be pulled conveniently; sliders 9 are connected to the pull plates 7, and the sliders 9 all slide in the slide rails 10, and the slide rails 10 are symmetrically arranged in the limit grooves 12; under the sliding action between the sliders 9 and the slide rails 10, the smooth efficiency of pulling the pull ring 8 to drive the limit rod 6 and the pull plate 7 to move is guaranteed; the inner wall of the hole of the limit groove 12 close to the side of the cover 3 for the limit rod 6 to slide is glued with a sealing gasket 13; under the use of the sealing gasket 13, the air tightness of the device during use is guaranteed.
