Description

A kind of coal-burning boiler filters chimney

Technical field

This utility model relates to Pollutant Treatment technical field, is specifically related to a kind of coal-burning boiler and filters chimney.

Background technology

Existing dedusting technology main operational principle comprises filtration and two kinds of parts of deashing, by dust in dusty gas Inertial collision, diffusion, intercept and electrostatic effect etc. acts on and realizing, but this cleaner unit is limited in high temperature by filtering material, In highly corrosive gaseous environment, adaptability is poor.

Utility model content

The purpose of this utility model is to provide a kind of coal-burning boiler to filter chimney, is filtered in order to solve existing cleaner unit Material be limited in high temperature, the problem that in highly corrosive gaseous environment, adaptability is poor.

For achieving the above object, this utility model provides a kind of coal-burning boiler to filter chimney.Specifically, including filtering dress Putting, described defecator is positioned at chimney, is provided with contaminant collecting device outside described chimney, and described defecator includes some Drainage screen, is provided with deflector below described drainage screen, described deflector and chimney connecting place are arranged over through hole, described pollutant Collection device lower end is provided with pollutant emission mouth.

Preferred version: described defecator is arranged over flue gas processing device.

Preferred version: described flue gas processing device is absorbent charcoal adsorber or flue gas desulfurization device.

Preferred version: be connected by filter screen bracket between described some drainage screens.

Preferred version: be equipped with a deflector below described some drainage screens.

Preferred version: described drainage screen is that stainless steel is constituted, and the aperture of described some drainage screens is the most successively Reduce.

Preferred version: spaced and parallel setting between described deflector.

Preferred version: described contaminant collecting device lower end is at least provided with pollutant emission mouth described in.

Preferred version: described deflector is 10-60 degree with the angle of chimney medial wall.

Preferred version: described deflector is 45 degree with the angle of chimney medial wall.

This utility model method has the advantage that 1, defecator is effectively combined into by this utility model with chimney Integrally, not taking up space, filtering material uses stainless steel metal filter material, the most high temperature resistant and anticorrosive, when boiler combustion, Filter plant will work.

Detailed description of the invention

Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.

A kind of coal-burning boiler provided for this utility model as shown in Figure 1-Figure 3 filters chimney, including defecator 1, mistake Filter device 1 is positioned at chimney 2, is provided with contaminant collecting device 3 outside chimney 2, and defecator 1 includes some drainage screens 11, mistake Being provided with deflector 4 below filter screen 11, deflector 4 and chimney 2 connecting place are arranged over through hole 5, and contaminant collecting device 3 lower end sets Having pollutant emission mouth 6, in this utility model, in coal-burning boiler, coal burning produces substantial amounts of gases, passes through chimney During discharge, flue gas importing one is discharged by smoke deflector 4 on the side, and the pollutant that drainage screen 11 is bigger by intercepting grain, due to quilt Intercepting the increase of pollutant, pollutant can drop on smoke deflector 4 due to gravity, is entered by through hole 5 landing The contaminant collecting device 3 of chimney 2 outer wall, after contaminant collecting device 3 internal contamination thing reaches to a certain degree, just from pollutant Floss hole 6 is discharged, thus the pollutant realizing producing coal-burning boiler filter.

In this utility model, defecator 1 is arranged over flue gas processing device, and further, flue gas processing device is for living Property charcoal adsorbent equipment 7 or flue gas desulfurization device 8, thus realize the structure by changing chimney, utilize the principle that hot-air rises Combine with the principle of activated carbon adsorption method, the pollutant produced when effectively filtering boiler combustion.As shown in Figure 1 and Figure 2, respectively For two kinds of different embodiments of the present utility model.

In this utility model, as it is shown on figure 3, be connected by filter screen bracket 12 between some drainage screens 11, can play Conveniently carry out dismantling, installing and fixing effect.

In this utility model, as in figure 2 it is shown, be equipped with a deflector 4, further, water conservancy diversion below some drainage screens 11 Spaced and parallel setting between plate 4, can play and preferably filter pollutant, and after the filtration that can be more prone to Pollutant discharge.

In this utility model, drainage screen 11 is constituted for stainless steel, and filtering material uses stainless steel metal filter material, more Big degree is high temperature resistant and anticorrosive, and when boiler combustion, filter plant will work, it is not necessary to external force.Further, some drainage screens The aperture of 11 is sequentially reduced from top to bottom, say, that in boiler, coal burning produces substantial amounts of gases, passes through chimney During discharge, flue gas importing one is discharged by smoke deflector on the side, and the pollutant that drainage screen is bigger by intercepting grain, owing to being blocked Cutting the increase of pollutant, pollutant can drop on smoke deflector due to gravity, and landing enters main body tube outer wall Contaminant collecting device, after contaminant collecting device internal contamination thing reaches to a certain degree, just discharges from pollutant emission mouth.Its In the filtering accuracy of every layer of drainage screen different, discharge order is from the end to height, and filtering accuracy is from small to large.Highest point filter screen filtration Precision should be maximum, just provides advantage with for flue gas desulfurization device.

In this utility model, contaminant collecting device 3 lower end at least provided with a pollutant emission mouth 6, preferably two, The effect of preferably discharging pollutants can be played.

In this utility model, deflector 4 is 10-60 degree with the angle of chimney 2 medial wall, more preferably, and 45 degree, More preferable water conservancy diversion and the effect discharged pollutants can be reached.

In this utility model, chimney 2 upper end is additionally provided with a bucker, can play waterproof effect.

Although, the most with general explanation and specific embodiment, this utility model is made detailed description, but On the basis of this utility model, can make some modifications or improvements it, this is apparent to those skilled in the art 's.Therefore, these modifications or improvements on the basis of without departing from this utility model spirit, belong to this utility model and want Seek the scope of protection.
