Knoisphere forms filter cake, influences filter effect.At this time, it may be necessary to carry out blowback to ceramic screen pipe.General blowback system is to pass through high pressure
Gas penetrates outward from the inside of ceramic screen pipe, filter cake is removed from the outer surface of ceramic screen pipe, to restore filtering efficiency.But
It is to still remain shortcoming：（1）Existing blowback system high pressure gas is dispersed in larger space after the ejection of blowback nozzle
In range, portion gas cannot import in ceramic screen pipe, and the pressure loss of high pressure gas is than more serious, the impact to ceramic screen pipe
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 purifier；（3）Current ceramic screen pipe is mostly cylinder, and filter area has
Limit.
In view of this, it is necessary to a kind of novel fire resistant ceramic fibre chimney filter be invented to defect in the prior art, with solution
The certainly above problem.
Invention content
It is an object of the invention to disclose a kind of novel fire resistant ceramic fibre chimney filter, blowback effect is improved, reduces and enters
The pressure loss in pyroceram fibre chimney filter reduces blowback system energy consumption, achievees the purpose that remove filter cake, while adding temperature
Self-compensation sealed layer is spent, high-temperature stress relaxation phenomenon is eliminated.
To achieve the above object, the present invention provides a kind of novel fire resistant ceramic fibre chimney filter, the refractory ceramicses
Fiber chimney filter inner wall is equipped with Venturi tube, and temperature self-compensation sealant, the Venturi tube and temperature are equipped at upper port outer wall
Self-compensation sealed layer 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 on the upside of temperature self-compensation sealant.
Compared with prior art, the beneficial effects of the invention are as follows：（1）Novel fire resistant ceramic fibre chimney filter inner wall is equipped with venturi
Pipe structure can utilize the venturi tube structure of pyroceram fibre chimney filter in for high-temperature flue gas controlling device, reduce anti-
The pressure loss that system sprays into pyroceram fibre chimney filter is blown, the energy consumption of blowback system is reduced, reaches the mesh for removing filter cake
's；（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, and is filtered
Area is bigger than the filter area of general round ceramic fiber chimney filter, and filter efficiency is high；（3）On novel fire resistant ceramic fibre chimney filter
Temperature self-compensation sealant is equipped at port outer wall, the thickness of sealant can increase with the raising of operating temperature, solve
Stress relaxation phenomenon under compressing member high temperature, to ensure the sealing in pyroceram fibre chimney filter and purifier between floral disc
Performance is not affected by temperature.

Specific implementation mode
The present invention is described in detail for each embodiment shown in below in conjunction with the accompanying drawings, but it should explanation, these
Embodiment is not limitation of the present invention, those of ordinary skill in the art according to function, method made by these embodiments,
Or the equivalent transformation in structure or replacement, all belong to the scope of protection of the present invention within.
Pyroceram fibre chimney filter 1 shown in Fig. 1-2,1 inner wall of pyroceram fibre chimney filter are equipped with Venturi tube
2, temperature self-compensation sealant 4, the Venturi tube 2 and temperature self-compensation sealant 4 and high temperature resistant are equipped at upper port outer wall
Ceramic fibre chimney filter 1 is an integral structure.Venturi tube 2 is made of inlet tube 21, collapsible tube 22, trunnion 23 and diffuser 24.
