Weaken, blowback effect is less desirable, in order to reach high-efficient reverse blowing effect, it is necessary to provide the gas of higher pressure, in this way
Energy consumption is improved again；(2) existing ceramic screen pipe does not resist the ability of compressing member high-temperature stress relaxation, often causes ceramic screen pipe
Sealing effect is bad at sealing with floral disc in purification device；(3) current ceramic screen pipe is mostly cylinder, and filter area has
Limit.
In view of this, it is necessary to ceramic screen pipe in the prior art be improved, to solve the above problems.
Summary of the invention
The purpose of this utility model is that disclosing a kind of novel fire resistant ceramic fibre chimney filter, blowback effect is improved, is reduced
The pressure loss into pyroceram fibre chimney filter reduces blowback system energy consumption, achievees the purpose that remove filter cake, increase simultaneously
If temperature self-compensation sealant, high-temperature stress relaxation phenomenon is eliminated.
To achieve the above object, the utility model provides a kind of novel fire resistant ceramic fibre chimney filter, the high temperature resistant
Ceramic fibre chimney filter inner wall is equipped with Venturi tube, is equipped with temperature self-compensation sealant at upper port outer wall, the Venturi tube and
Temperature self-compensation sealant is an integral structure with pyroceram fibre chimney filter.
In some embodiments, the Venturi tube is arranged close to pyroceram fibre chimney filter upper port.
In some embodiments, the pyroceram fibre chimney filter is enclosed by three elongate member head and the tail connections,
The elongate member cross section is in crescent.
In some embodiments, flange, the flange and temperature are connected at the top of the pyroceram fibre chimney filter
Self-compensation sealed layer closely connects, and is located on the upside of temperature self-compensation sealant.
Compared with prior art, the utility model has the beneficial effects that (1) novel fire resistant ceramic fibre chimney filter inner wall is set
There is venturi tube structure, in high-temperature flue gas controlling device, the Venturi tube knot of pyroceram fibre chimney filter can be utilized
Structure reduces the pressure loss that blowback system sprays into pyroceram fibre chimney filter, reduces the energy consumption of blowback system, reach removing
The purpose of filter cake；(2) novel fire resistant ceramic fibre chimney filter is connected by the elongate member head and the tail that three cross sections are crescent and is enclosed
It forms, filter area is bigger than the filter area of general round ceramic fiber chimney filter, and filter efficiency is high；(3) novel fire resistant ceramics
Temperature self-compensation sealant is equipped at fiber chimney filter upper port outer wall, the thickness of sealant can increase with the raising of operating temperature
Add, solve stress relaxation phenomenon under compressing member high temperature, to guarantee floral disc in pyroceram fibre chimney filter and purification device
Between sealing performance be not affected by temperature.
