Abstract
The utility model discloses an abrasive-resistant bent pipe used in gas-solid and liquid-solid conveying systems. In the two-phase flow systems of gas-solid and liquid-solid of pneumatic conveying, the bent pipe part and the straight pipe part of a feed port are worn out by the erosion of solid particles. An expanding angle is arranged on the inlet part of the beam-expanding flow-guiding type abrasive-resistant bent pipe designed by the utility model, and the inner part of the bent pipe is provided with a flow-guiding sheet. A feeding uses a symmetrical or multi-symmetrical feed port structure. Thus, the erosion wear of the solid particles to a pipeline are decreased, and the service life of the whole pipeline system is enhanced. With simple structure and low cost, the utility model is abrasive resistance, and prevents part of the pipe wall being worn out and prolongs the service life of the pipeline.
Description
Technical field is that strength is carried under the utility model.
Gu in--solid, liquid--two-phase delivery system, as air-transport system, common is bend pipe to the most serious member of pipeline localized wear at gas.People prolong the service life of pipeline in order to reduce because of the erosive wear of body particle to the pipeline part, once dream up multiple scheme.Present home and abroad adopts high hardness material to make to the most serious member of localized wear more or easily changeable structure is made at the position that localized wear is the most serious, and the former improves a whole set of guard system cost, and the latter increases maintenance load greatly.
The purpose that the present utility model is created is a kind of bend pipe that resistance to wears of innovation and creation in order to solve problems of the prior art, thereby has improved the wear resistance of pipeline greatly.
The fundamental point that the present utility model is created is: carry in strength, Gu the bend pipe that resistance to wears in gas--solid, liquid--the two-phase delivery system is for expanding bundle flow-guiding type bend pipe, promptly the angle of flare (1) is arranged, flow deflector (2) (see figure 1) is set in bend pipe in bend pipe inflow point.
Accompanying drawing:
Fig. 1 expands the bundle flow-guiding type bend pipe structure scheme drawing that resistance to wears
Fig. 2 symmetry inlet point element structure scheme drawing that resistance to wears
Below in conjunction with description of drawings structure of the present utility model.
In the moving system of--solid, liquid--fixed double phase flow, such as air-transport system, usually see the pipe bent position at pipeline, owing to solid particle erosion is worn through at gas. This erosive wear is not the tube wall that weares and teares equably, but concentrate some local location of wearing and tearing, cause shorten the service life of whole pipeline, particularly when the particle velocity height of carrying, concentration is big, and material is hard, when corner angle light is sharp, concentrated wear is even more serious, and people notice how to reduce always Grain is to the erosive wear of pipeline, to improve the service life of a whole set of pipe-line system.
The utility model is according to erosion wear theory and experimental result, abrasion loss 2.5 powers about and granule impact speed are directly proportional, and increase with granule density and hardness, pipeline to carbon steel or manganese steel material, the particle angle of attack is 20～30 maximums of abrasion loss when spending, thereby the wear-resistant structure form of designing bend pipe is as follows.
Gu bend pipe is a curved channel in--solid, liquid--two-phase delivery system at gas because the centrifugal inertial force effect, make particle intensive dash cut bend pipe lateral wall (3) and be directed at tube wall and be worn through.The utility model design-calculated expands the bundle flow-guiding type bend pipe (see figure 1) of resistance to wearing can greatly alleviate this kind wearing and tearing.
Expand the bundle flow-guiding type bend pipe that resistance to wears, promptly there is the individual angle of flare (1) that flow deflector (2) is set in bend pipe in bend pipe inflow point, when fluid enters bend pipe, because flow area increases, speed reduces, because of the body particle speed also reduces thereupon, because effect of inertia, most of particulate matter enters centre gangway (4), and the concentration of solid particles that impacts bend pipe lateral wall (3) reduces greatly.Thereby this expansion bundle flow-guiding type bend pipe has good antifriction effect.
Embodiment
Strength is carried in the industry, solid i.e. gas--in the two-phase delivery system, inlet point (5) straight length (6) and bend pipe composition is arranged.Be easy to be worn through at unidirectional inlet point (5) straight length (6) position, locate at inlet point (5), individual Rotary feeder (7) is arranged, material radially has an initial velocity at pipeline, thereby most of particle dashes at an angle and cuts straight length (6) tube wall, and it is two-way or multidirectional symmetrical inlet point (5) structure (see figure 2) that the utility model embodiment proposes charging.Make like this that the mutual collision owing to self concentrates on tube hub (8) between the particulate matter in the two phase flow, enter the bend pipe that resistance to wears from straight length then, reach the purpose that two-phase is carried, thereby reduced erosive wear tube wall.
The bend pipe Gu resistance to wear in the gas that the utility model is designed--solid, liquid--the two-phase delivery system, symmetrical inlet point, simple in structure, cost is low, and under the situation that does not increase resistance to flow, it resistance to wears, prevent that the tube wall part is worn out, prolong pipeline service life, effect is remarkable.
Claims (2)
- Gu 1, the bend that resistance to wears of a kind of gas that is used for--solid, liquid--two-phase delivery system is characterized in that this bend pipe for expanding the bundle flow-guiding type bend pipe that resistance to wears, has the angle of flare (1) in bend pipe inflow point, and flow deflector (2) is set in bend pipe.
- 2, according to the bend pipe that resistance to wears of the expansion bundle flow-guiding type in the said gas of claim 1--solid, liquid--the fixed double phase flow system, it is characterized in that inlet point (5) and straight length (6) are arranged in the front of this bend pipe, its inlet point (5) is a symmetry, how symmetrical inlet point (5).
