Abstract
The utility model provides a dedusting flue which is used for processing smoke exhausted by a boiler and the like and collecting harmful matter in the smoke before the smoke is exhausted into air to prevent the harmful matter from polluting the air. The dedusting flue comprises a flue body which comprises a dedusting section which is in the shape of a Chinese character 'ji' and formed by connecting horizontal pipelines and vertical pipelines. Water spray nozzles are arranged in the dedusting section, and drain pipes are arranged at the bottom of the dedusting section. In the flowing process of the smoke along the dedusting section, the water spray nozzles spray water towards the smoke, water can adsorb dust in the smoke and can dissolve NO, NO2 and sulfur compound in the smoke, and dust and harmful matter are prevented from being exhausted to the air. Water with dissolved harmful matter is drained through the drain pipes and can be further processed, and details of the further processing step are omitted here. The dedusting section in the shape of the Chinese character 'ji' can increase collision probability of the smoke and the wall of the flue so that the probability that the smoke is adsorbed on the wall of the flue can be increased, and the smoke adsorbed on the wall of the flue is finally drained along with water flow to be further processed.
Description
Technical field
The utility model relates to a kind of dust-removing flue.
Background technology
Now a lot of boilers are also being used coal or faggot, timber etc. to make fuel, after these fuel combustions, can produce a large amount of flue dust, contain NO, NO in these flue dust
2and the harmful substance such as sulfur-containing compound, if these flue dust are directly discharged in atmosphere, can cause serious air pollution, be therefore necessary flue dust to process, before entering atmosphere, the harmful substance in flue dust is collected, avoid its atmosphere pollution.
Summary of the invention
The purpose of this utility model is to propose a kind of dust-removing flue, for the flue dust of the discharges such as boiler is processed, before flue dust enters atmosphere, harmful substance in flue dust is collected, and avoids its atmosphere pollution.
Dust-removing flue of the present utility model comprises flue body, and key is that described flue body comprises " several " font dedusting section being formed by connecting by horizontal pipe and vertical pipe, in described dedusting section, is provided with water spout, and the bottom of dedusting section is provided with drainpipe.
In the flue gas process mobile along dedusting section, water spout is sprayed water to it, and water not only can adsorb the dust in flue gas, and can dissolve NO, NO in flue gas
2and sulfur-containing compound etc., avoid dust and harmful substance to be discharged in atmosphere.The water that is dissolved with harmful substance is discharged through drainpipe, can process further it, repeats no more herein." several " font dedusting section can increase the impact machine meeting of flue dust and tube wall, thereby increases the chance that flue dust is adsorbed on tube wall, and the flue dust that is adsorbed on tube wall finally can be discharged with current, then processes.
Further, be dedusting better and absorption harmful substance, horizontal pipe and vertical pipe in described dedusting section are equipped with water spout.
Further, the vertical pipe in described dedusting section is provided with filter screen, and the water spout in vertical pipe is arranged at the top of filter screen and towards filter screen.Filter screen can delay the speed of flue gas, and is conducive to adsorb dust, and the globule sticks on filter screen, can expand water and NO, NO
2and the contact area of the harmful substance such as sulfur-containing compound, and then improve dust treatment effect.
Further, horizontal pipe in described dedusting section is provided with the hush pipe that diameter is greater than all the other position diameters of horizontal pipe, described hush pipe is provided with filter screen, and the water spout in horizontal pipe is arranged at the side of filter screen and towards filter screen, described drainpipe is located at the bottom of hush pipe.Because the diameter of noise reduction section is greater than all the other position diameters of horizontal pipe, so the cavity of noise reduction section can delay the flowing velocity of flue gas, and filter screen and water spout are set herein, can to flue dust, carry out adsorption treatment better.
Further, described flue body is provided with air exhauster in the discharge directions of dedusting section, for improving the smoke evacuation ability of flue.
Dust-removing flue of the present utility model is relatively simple for structure, is easy to realize, and can effectively improve the discharge of boiler smoke, avoids the smoke contamination atmosphere in flue gas, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of dust-removing flue of the present utility model.

In the flue gas process mobile along dedusting section 4, water spout 5 is to its water spray, and water not only can adsorb the dust in flue gas, and can dissolve NO, NO in flue gas
2and sulfur-containing compound etc., avoid dust and harmful substance to be discharged in atmosphere.The water that is dissolved with harmful substance is discharged through drainpipe 9, can process further it, repeats no more herein." several " font dedusting section 4 can increase the impact machine meeting of flue dust and tube wall, thereby increases the chance that flue dust is adsorbed on tube wall, and the flue dust that is adsorbed on tube wall finally can be discharged with current, then processes.
Filter screen 6,8 can delay the speed of flue gas, and is conducive to adsorb dust, and the globule sticks on filter screen 6,8, can expand water and NO, NO
2and the contact area of the harmful substance such as sulfur-containing compound, and then improve dust treatment effect.
