Abstract
The invention relates to a ceramic desulfuration pipeline. The ceramic desulfuration pipeline comprises a ceramic desulfuration pipeline body and two flange discs installed at the two ends of the ceramic desulfuration pipeline body, wherein the two ends of the ceramic desulfuration pipeline body are installed in central flange holes of the two flange discs respectively in an insertion manner and are welded, and the end surfaces of the two ends of the ceramic desulfuration pipeline body are lower a preset distance than the corresponding end surfaces of the flange discs respectively; and a ring of ceramic protection layer is cured outside the end surfaces of the two ends of the ceramic desulfuration pipeline body. According to the ceramic desulfuration pipeline disclosed by the invention, the end surfaces of the ceramic desulfuration pipeline body can be protected through the ceramic protection layer, and are prevented from damage during a use process due to wear or corrosion because of no protection of a ceramic material on the end surfaces of the ceramic desulfuration pipeline body, thus the service life of the ceramic desulfuration pipeline is prolonged, and the maintenance and repair costs are reduced.
Description
Technical field
The invention belongs to earthenware duct technical field, and in particular to a kind of desulfurization earthenware duct.
Background technology
Desulfurization system for thermal power plant has the characteristics that：Big with corrosivity, abrasion.In desulfurization system for thermal power plant
Used in common steel tube will be damaged using one month, be therefore developed special desulfurization earthenware duct and send out for firepower
Power plant desulphurization system.
Current desulfurization earthenware duct is formed using pipe lining ceramic material, and ceramic material is by aluminium sesquioxide, carbonization
Silicon, resin composition.Above material is applied to steel pipe inner wall using specific purpose tool after mixing, through the solidification of 3-4 hour is
Normally can use.
In use, it has been found that existing desulfurization earthenware duct be easy in use due to abrasion, corrosion and
Cause to damage, particularly attrition and attack is highly susceptible at desulfurization earthenware duct flange port, so as to reduce desulfurization pottery
The service life of pipeline, accordingly, it would be desirable to improve, to overcome the defect.
Content of the invention
It is an object of the invention to solving above-mentioned technical problem and providing a kind of the de- of service life that can extend pipeline
Sulfur earthenware duct.
For achieving the above object, the present invention is adopted the following technical scheme that：
A kind of desulfurization earthenware duct, including desulfurization earthenware duct body and installed in the desulfurization earthenware duct body
Two ring flanges at two ends, the two ends of the desulfurization earthenware duct body are inserted into the center flange of two ring flanges respectively
In the hole is simultaneously welded, and the end face at the two ends of the desulfurization earthenware duct body is respectively lower than the corresponding end face one with the ring flange
Section predeterminable range, is solidified with a circle ceramic protective layer outside the end face at the two ends of the desulfurization earthenware duct body.
One section of predeterminable range is 8-10mm.
The thickness of the ceramic protective layer is consistent with one section of predeterminable range, internal diameter and the desulfurization earthenware duct body
Internal diameter consistent.
The end face that the present invention passes through at the two ends of the desulfurization earthenware duct body is respectively lower than right with the ring flange
One section of predeterminable range of end face is answered, a circle ceramic protective layer outside the end face at the two ends of the desulfurization earthenware duct body, is solidified with, can
To be protected to the end face of desulfurization earthenware duct body by the ceramic protective layer, prevent in use due to the desulfurization
The end face of earthenware duct body no ceramic material protection and because wear and tear or corrosion and impaired, so as to extend desulfurization earthenware duct
Service life, reduces maintenance and maintenance cost.
Description of the drawings
The schematic diagram of Fig. 1 desulfurization earthenware duct provided in an embodiment of the present invention.
Specific embodiment
Below, in conjunction with example, the substantive distinguishing features of the present invention and advantage are further described, but the present invention not office
It is limited to listed embodiment.
Shown in Figure 1, a kind of desulfurization earthenware duct, including desulfurization earthenware duct body 10 and installed in the desulfurization
Two ring flanges 11 at the two ends of earthenware duct body, the two ends of the desulfurization earthenware duct body are inserted into described in two respectively
The center flange in the hole of ring flange is simultaneously welded, and the end face at the two ends of the desulfurization earthenware duct body is respectively lower than and the method
One section of predeterminable range of the corresponding end face of blue disk, is solidified with circle pottery and protects outside the end face at the two ends of the desulfurization earthenware duct body
Sheath 12.
When specifically used, reserve certain surplus when ring flange is welded with desulfurization earthenware duct, make ring flange port with
The corresponding ports of desulfurization earthenware duct can produce a space not on a horizontal plane, thus, using pottery in this space
Ceramic material is filled with, and is so strengthened in the weak link of pipeline, so as to increase the bulk life time of pipeline.
Material used by the ceramic protective layer is consistent with the material being coated on desulfurization earthenware duct inwall.
Wherein, implement, one section of predeterminable range is 8-10mm.
Wherein, implement, the thickness of the ceramic protective layer is consistent with one section of predeterminable range, internal diameter with described
The internal diameter of desulfurization earthenware duct body is consistent.
The end face that the present invention passes through at the two ends of the desulfurization earthenware duct body is respectively lower than right with the ring flange
One section of predeterminable range of end face is answered, a circle ceramic protective layer outside the end face at the two ends of the desulfurization earthenware duct body, is solidified with, can
To be protected to the end face of desulfurization earthenware duct body by the ceramic protective layer, prevent in use due to the desulfurization
The end face of earthenware duct body no ceramic material protection and because wear and tear or corrosion and impaired, so as to extend desulfurization earthenware duct
Service life, reduces maintenance and maintenance cost.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
