Abstract
The utility model aims to provide a pipe section which is capable of bearing the strong abrasion after a throttling element on a slurry pipeline.Therefore, the technical scheme of the utility model is to provide a compound pipe section, which comprises an inner pipe and an outer sleeve which is connected with the periphery of the inner pipe, and is characterized in that the length of the pipe section is 2-5 times of the inner diameter of the inner pipe, and the inner pipe is more wear-proof than the outer sleeve. On the other side, the utility model further provides a liquid-solid mixing slurry pipeline, which comprises a throttling element and the compound pipe section in the front side, and the compound pipe section is close to the throttling element. The utility model is capable of achieving the technical effects that the inner pipe is made of materials with high hardness and optimally selected Al2O3 ceramic, thereby parts after the throttling element in the pipeline is capable of bearing the strong abrasion of the slurry. The whole liquid-solid mixing slurry pipeline only locally uses the compound pipe section according to the utility model, other parts are capable of using a common rubber lining pipeline, therefore the whole cost is controlled to be very low.
Description
Technical field
The utility model belongs to the chemical machinery technical field, relates to a kind of wear-resisting compound pipeline section and the liquid-solid mixed serum pipeline of this pipeline section of employing.
Background technique
Usually use the limestone-gypsum law technology at present in the generating plant flue gas desulfurization, the slurries that this technology is carried comprise lime stone slurry and gypsum slurries.Usually slurries are acidity or alkalescent, and corrosivity is stronger, and the solid that wherein contains especially has stronger abrasion pipeline ability.General slurries pipeline adopts line with rubber pipeline or stainless steel pipeline.On these pipelines, usually can arrange throttling elements such as some orifice plates, valve; pipeline position behind throttling element; because the contraction-expansion of slurries has formed strong disturbance; can occur the unusual serious situation of pipe wear; at this moment common line with rubber pipeline or stainless steel pipeline just can not bear the wearing and tearing of degree like this, and will shorten working life.
Chinese patent 97106643 discloses a kind of composite steel pipe with ceramic resin lining and manufacture method thereof, adopt the pipeline of this way manufacturing can tolerate the corrosion and the wearing and tearing of slurries, has using effect preferably, but be suitable for the longer pipe road, if all pipeline all adopts this pipeline, cost is higher.Chinese patent 200310114565.4 discloses the manufacture method of another ceramic composite pipe, adopts pottery, glass fibre reinforced plastics and intermediate connecting layer to make composite pipe, also has similar problem.
The model utility content
In order to solve above-mentioned the problems of the prior art, the purpose of this utility model is to provide a kind of high-wearing pipeline section behind the throttling element that can tolerate on the slurries pipeline.For this reason, designer of the present utility model has carried out a large amount of experimental calculation research, discovery length after the ducted throttling element of slurries is in the position of about 2-5 times pipe diameter, it is very serious because the contraction of slurries-expansion forms strong disturbance to the wearing and tearing of pipeline, but for other pipe sections beyond this position, wear problems is not very serious, adopts common line with rubber pipeline just can have very long working life.
On the one hand, the technical solution of the utility model is: a kind of compound pipeline section is provided, comprises: interior pipe; Be bonded on described interior pipe overcoat on every side; It is characterized in that, the length of described pipeline section be described in pipe inner diameter 2-5 doubly, and pipe is more wear-resisting than described overcoat in described.
Preferably, described interior pipe is made by pottery, and described overcoat is made by glass fibre reinforced plastics.Most preferably, described interior pipe is by Al
2O
3Pottery is made.Like this, the stupalith of pipe provides the pipeline section abrasive resistance in utilizing, and utilizes the glass fibre reinforced plastic material of overcoat that outer protection to pipeline section is provided.
On the other hand, the technical solution of the utility model is: a kind of liquid-solid mixed serum pipeline is provided, comprises: throttling element; And with the basis of described throttling element adjacency before described compound pipeline section on the one hand.
The technique effect that the utility model can be realized is: utilize the material of high hardness, preferred Al
2O
3Pottery is managed in making, and can make the strong wear of the tolerance of the position after throttling element slurries in the pipeline.Length of pipe section is shorter in addition, and manufacturing all is easy to.And the glass fibre reinforced plastic material of overcoat is very easy to be wrapped in the ceramic inner pipe outside, and has certain intensity, and the stupalith of pipe is well protected in can giving.Simultaneously, whole liquid-solid mixed serum pipeline is that has adopted according to compound pipeline section of the present utility model the part, and remaining part can adopt common line with rubber pipeline, and therefore whole cost control must be lower.
