Description
Technical field
The utility model relates to a kind of flue gas particles capturing devices based on peripheral flow principle, belong to environmental protection equipment skill
Art field.
Background technique
With continuing to increase for environmental pollution improvement, China dynamics, various industries require to get over to the discharge standard of industrial smoke
Come higher.Bag filter formula deduster (hereinafter referred to as " bag filter ") is the most general as applying in current flue gas de-dusting process
And a kind of cleaner, it has harsh requirement to temperature, the quality of flue gas particles, if the temperature of particulate matter is excessively high,
The overlay film that damage cloth bag external surface layer can then be scalded, causes dust removing effects to reduce, What is more can cause fire and burn cloth bag；If
The quality of grain object is excessive, then can be because (reachable 15 meter per seconds or so), momentum are big fastly for its speed, and the surface layer overlay film pole outside cloth bag holds
It is easily damaged, dedusting effect is caused to decline.Effect is captured to the interception of flue gas particles, will seriously affect dust-collecting bag
Service life and dust removing effects therefore, must to intercept process to the pass of its particulate matter before flue gas enters bag filter
It wants.
According to the interception principle of flue gas particles, current capturing device is roughly divided into two classes: baffle-type, cyclone type.Gear
Board-like capturing device: installing some vertical baffles additional in the closed case being connected with flue, and after particulate matter impingement baffles, speed subtracts
It is small, the kinetic energy for continuing to fly upward is lost, is deposited among the ash bucket of lower section under the effect of gravity.Cyclone type capturing device: dust constaining
Autogenous cutting is to the cyclone cylinder entered inside device, and under the turning effort of cyclone cylinder, flue gas sinks down into centrum bottom in the shape of a spiral,
Then again under the action of the lesser spiral reverse of diameter revolves upwards, the discharge of device top exit, in the process, particulate matter are risen to
By the effect of centrifugal force, thrown to device wall, then among the ash bucket that wall is snapped down to centrum bottom.
It analyzes from the working mechanism of above-mentioned two classes capturing device it is found that the two still has common shortcoming: first, two
Person is independently of the dust-extraction unit system except flue, they are seized of oneself exclusive space place respectively, this is right
It is a kind of pressure for the land used of close-packed plant produced scene；Second, whether vertical baffle keep out the wind or cyclone cylinder
Spinning movement, all can additionally increase a large amount of kinetic equation loss；Third, the structure of the two is relative complex, construction cost is higher.
In view of this, breaking through the working mechanism bottleneck of existing capturing device, overcomes the above-mentioned deficiency of capturing device, inquire into out
A kind of significantly more efficient working mechanism, and a kind of novel more excellent replacement device product is invented accordingly, become of the invention
Basic goal.
