Embodiment 1

[0018] Embodiment one: if figure 1 and figure 2 The shown flue gas dust removal box with dust removal mechanism includes a box body 2 with water at the bottom, and three partitions 6 are arranged inside the box body 2, and the three partition boards 6 divide the box body 2 into four dust removal chambers. The partition plate 6 is provided with a drainage pipe 5 communicating with the adjacent dedusting chamber. A smoke inlet pipe 1 is arranged on the leftmost dust removal chamber, and a smoke exhaust pipe 7 is arranged on the rightmost dust removal chamber. A pipe cleaning mechanism is sheathed on the outside of the smoke inlet pipe 1 . The pipe cleaning mechanism includes a telescopic pipe 8 composed of four branch pipes slidingly connected. A branch pipe located at the lowermost end is fixedly connected with the side wall of the box body 2 . The three branch pipes above are provided with a water storage tray 4, which is welded to the bottom of the branch pipes, and the ...

Embodiment 2

[0019] Embodiment two: if image 3 As shown, the difference from Embodiment 1 is only that the blade of the scraper 3 is slidably connected to the telescopic tube 8, and a spring is provided at the end of the blade away from the intake pipe, and the spring is fixedly installed on the telescopic tube 8.

[0020] When in use, the flue gas enters the box body 2 through the smoke inlet pipe 1. Since the lower part of the smoke inlet pipe 1 is provided with a telescopic pipe 8, after the smoke enters the telescopic pipe 8, the telescopic pipe 8 is elongated under the action of the flue gas. The telescopic tube 8 pushes the scraper 3 to move upward. When the scraper 3 moves upward along the smoke inlet pipe 1, the scraper 3 scrapes off the dust accumulated on the surface of the smoke inlet pipe 1. At the same time, when the telescopic tube 8 is stretched, the storage The water pan 4 will rise together with the branch pipe, the water in the water storage pan 4 will flow out from the ...

Abstract

This patent discloses a flue gas dust removal box with a dust removal mechanism, which includes a box with water at the bottom. The box is provided with a number of vertically arranged partitions. The box is provided with a smoke inlet pipe and a smoke outlet. pipe, the partition board is provided with a drainage pipe, and the outside of the smoke inlet pipe is equipped with a pipe cleaning mechanism. The pipe cleaning mechanism includes a telescopic pipe composed of several branch pipes, and the adjacent branch pipes are slidingly connected. The lower end of the telescopic tube is connected to the box body. The telescopic tube is provided with a number of through holes. The top of the telescopic tube is provided with a scraper. The lower part of the branch pipe is provided with a water storage tray. The water storage tray is fixedly connected to the branch pipe. , a number of drain holes are provided between the water storage pan and the branch pipe; this solves the problem in the prior art that dust is easily accumulated on the outer wall of the smoke inlet pipe and causes corrosion.

Description

technical field [0001] The invention relates to flue gas dedusting equipment, in particular to a dedusting device for sodium sulfide production. Background technique [0002] Sodium sulfide needs to use a combustion furnace in the production process. When the combustion furnace is in use, a large amount of flue gas will be generated. The flue gas contains a lot of solid particles. If the flue gas is directly discharged into the air, it will cause certain pollution. Therefore, it is necessary to use a dust removal device to remove dust from the flue gas. Most of the existing dust removal devices use water spray to form a water film to remove dust, but such devices will cause waste of water. The existing publication number is CN102008863 B, and the patent name is a boiler water film dust collector, which discloses a casing, a smoke inlet pipe, a smoke outlet pipe, a diversion pipe, a dust removal chamber and a water ash tank; The first-level dust removal chambers are connect...
