Description
Technical field
The utility model relates to a kind of piecing devices, particularly relates to a kind of thermal electric generation ash-transmission system Geldart-D particle piecing devices.
Background technology
Double-jacket tube malleation thick and thin phase burner technology, in thermal powerplant widespread use, finds that the inner and outer pipe of double-jacket tube all exists the situation of privileged site serious wear in actual applications.Analyze for this Study on Problems, find that the interior pipe of two pipeline connecting places is that contact connects, inevitably there is gap in two inner sleeve junctions, pressurized air can spray at a high speed from gap and change convey materials normal condition, define irregular strong turbulent flow, thus result in the severe wear of pipeline.In addition, for a long time under the operating mode of high pressure draft erosive wear, there is caducous bad phenomenon in inner sleeve, and may cause pipe choking, many impacts such as grey library facilities bite, also just extremely urgent to the reinforcing of inner sleeve.
Utility model content
The purpose of this utility model is to solve Problems existing in current techniques, provide a kind of reduce ash conveying pipe abrasion factor be applicable to thermal electric generation ash-transmission system Geldart-D particle piecing devices.
For achieving the above object, the technological means that the utility model adopts is: a kind of thermal electric generation ash-transmission system Geldart-D particle piecing devices, comprise interpolation pipe and be socketed in the connection collar on interpolation pipe external diameter, the length of described interpolation pipe is 15-25cm, the length of the described connection collar is 2-5mm, and the external diameter of described interpolation pipe is slightly less than the internal diameter of inner sleeve.
Further, the external diameter of the described connection collar is identical with internal diameter with the external diameter of inner sleeve with internal diameter.
Further, the described connection collar is arranged on the centre of interpolation pipe and full weld connects.
Further, described interpolation pipe wall thickness 5mm, material is #45 carbon steel pipe or wear-resistant steel pipe.
The beneficial effects of the utility model are: bite type connection eliminates docking and connects gap, pressurized air is avoided to sentence having multiple changing angle blowout in connection gap, the state affecting Dual-Phrase Distribution of Gas olid changes, after Optimizing Reconstruction, double-jacket tube ash conveying pipe operating mode is very stable, original Pipeline Leakage Point is eliminated substantially, reduce in the year of Pipeline Leakage Point and reach more than 94%, more than 8 years can be promoted to by 4 years of designing the service life of ash conveying pipe simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, interpolation pipe, 2, connect the collar, 3, inner sleeve, 4, ash conveying pipe.
Detailed description of the invention
A kind of thermal electric generation ash-transmission system Geldart-D particle piecing devices as shown in Figure 1, the connection collar 2 comprising interpolation pipe 1 and be socketed on interpolation pipe external diameter, the length of described interpolation pipe 1 is 15-25cm, the length of the described connection collar 2 is 2-5mm, and the external diameter of described interpolation pipe 1 is slightly less than the internal diameter of inner sleeve 3.
The external diameter of the described connection collar 2 is identical with internal diameter with the external diameter of inner sleeve 3 with internal diameter.
The described connection collar 2 is arranged on the centre of interpolation pipe 1 and full weld connects.
Described interpolation pipe 1 wall thickness 5mm, material is #45 carbon steel pipe or wear-resistant steel pipe.
For the ￠ 245mm ash conveying pipe of electric precipitation one, two electric field, its inner sleeve external diameter ￠ 76mm, internal diameter ￠ 66mm.
1, get a long 20cm, external diameter ￠ 65mm, thickness 5mm, material is that the carbon structural steel pipe of #45 steel or wear-resistant steel pipe are as interpolation pipe 1.
2, get one section of external diameter ￠ 76mm, the annulus of internal diameter ￠ 66mm, long 3mm is as the connection collar 2.
3, the interpolation pipe 1 of external diameter ￠ 65mm is inserted in the annulus connecting the collar 2, and make annulus in the position, middle of interpolation pipe.
4, the connection collar 2 and interpolation pipe 1 are carried out full weld.
When 5, ash conveying pipe 4 is installed, at the connection location of two joint ash conveying pipes 4, the both sides pipe of piecing devices complete for welding is inserted in the inner sleeve 3 of two ash conveying pipes 4 respectively.
6, flanges, spirally wound gasket, bolt is adopted by two ash conveying pipes inserting piecing devices to carry out installation fastening or directly ash conveying pipe is carried out seamless welding.
Joint of the present utility model makes interior pipe connection mode transform bite type connection as by direct contact type, eliminate docking and connect gap, pressurized air is avoided to sentence having multiple changing angle blowout in connection gap, the state affecting Dual-Phrase Distribution of Gas olid changes, there is gap and cause pressurized air ejection at a high speed in interior pipe junction, the state changing original Dual-Phrase Distribution of Gas olid is in causing, the major cause of outer tube severe wear, through redesigning, inner sleeve connection mode is transform as bite type and connect elimination connection gap, after Optimizing Reconstruction, double-jacket tube ash conveying pipe operating mode is very stable, original Pipeline Leakage Point is eliminated substantially, reduce in the year of Pipeline Leakage Point and reach more than 94%, more than 8 years can be promoted to by 4 years of designing the service life of ash conveying pipe simultaneously.
When plant area's mounting condition license, increase the length of double-jacket tube ash conveying pipe finished product as far as possible, to reduce the quantity of ash conveying pipe jointing, thus avoid inner sleeve to connect the generation in gap as far as possible.The place improving and optimizating applicable any this technology of employing of double-jacket tube ash conveying pipe, such as the conveying of dry slag, agstone, fly ash etc., has wide range of applications, and economic benefit and the social benefit of its generation are very huge.
The embodiment of the present application is just for illustration of technical characteristic disclosed in the present application, and those skilled in the art, by simply replacing the change carried out, still belong to the scope that the application protects.
