Abstract
The utility model relates to a kind of water-coal-slurry mixing and feeding device.It comprises fluid delivery pump and blending transportation pipe, and the liquid outlet of fluid delivery pump is connected by the inlet of pipeline with blending transportation pipe, and the discharging opening of blending transportation pipe is connected with reactor by pipeline.The sidewall of described blending transportation pipe has charging aperture, and this charging aperture is connected with storage tank by pipeline, and this pipeline has valve, and storage tank is positioned at the top of blending transportation pipe.Be characterized in that the diameter of described blending transportation pipe is first reduce gradually to increase gradually from its one end to the other end again.Adopt this mixing and feeding device to carry out blending transportation water-coal-slurry, the energy of consumption is less, extends the service life of fluid delivery pump.
Description
Technical field
The utility model relates to a kind of pay-off, is water-coal-slurry mixing and feeding device specifically.
Background technology
Water-coal-slurry is widely used in the industries such as chemical industry, electric power, metallurgy as a kind of novel, efficient, clean coal derived fuel.All know in industry, water-coal-slurry in use, needs water-coal-slurry to be delivered in reactor with mixing and feeding device to use.
At present, the water-coal-slurry mixing and feeding device used in industry comprises fluid delivery pump and blending transportation pipe, and the liquid outlet of fluid delivery pump is connected by the inlet of pipeline with blending transportation pipe, and the discharging opening of blending transportation pipe is connected with reactor by pipeline; The sidewall of described blending transportation pipe has charging aperture, and this charging aperture is connected with storage tank by pipeline, and this pipeline has valve, and storage tank is positioned at the top of blending transportation pipe.Pay-off in use, first the inlet of fluid delivery pump is connected with water source by pipeline, then fluid delivery pump is started, water is delivered in blending transportation pipe, then open valve, make the higher water-coal-slurry of concentration in storage tank enter into blending transportation pipe, slowly mix while the water-coal-slurry that then concentration is higher and water advance in blending transportation pipe, obtain the water-coal-slurry of low concentration, and be delivered in reactor and react.The straight tube that the blending transportation Guan Weiyi diameter of traditional water-coal-slurry mixing and feeding device is constant, the larger pressure needing fluid delivery pump to provide normally could carry water-coal-slurry, and the energy of consumption is more, and the service life of fluid delivery pump is shorter.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of water-coal-slurry mixing and feeding device, and adopt this mixing and feeding device to carry out blending transportation water-coal-slurry, the energy of consumption is less, extends the service life of fluid delivery pump.
For solving the problem, provide following technical scheme:
Water-coal-slurry mixing and feeding device of the present utility model comprises fluid delivery pump and blending transportation pipe, and the liquid outlet of fluid delivery pump is connected by the inlet of pipeline with blending transportation pipe, and the discharging opening of blending transportation pipe is connected with reactor by pipeline.The sidewall of described blending transportation pipe has charging aperture, and this charging aperture is connected with storage tank by pipeline, and this pipeline has valve, and storage tank is positioned at the top of blending transportation pipe.Be characterized in that the diameter of described blending transportation pipe is first reduce gradually to increase gradually from its one end to the other end again.
Wherein, the inlet diameter of described blending transportation pipe and discharging opening equal diameters.
Take above scheme, have the following advantages:
First gradually reduce again gradually increase from its one end to the other end due to the diameter of blending transportation pipe in water-coal-slurry mixing and feeding device of the present utility model.So water-coal-slurry is at the blending transportation pipe do not waited through cross section, negative pressure appearance can be produced at little tangent plane place, thus be just equivalent to be formed in blending transportation pipe one motive force forward, the discharge pressure that water-coal-slurry is needed when proper flow is less, reduce the operate power of fluid delivery pump, save the energy, extended and grown the service life of fluid delivery pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of water-coal-slurry mixing and feeding device of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, water-coal-slurry mixing and feeding device of the present utility model comprises fluid delivery pump 1 and blending transportation pipe 2, the liquid outlet of fluid delivery pump 1 is connected by the inlet of pipeline with blending transportation pipe 2, and the discharging opening of blending transportation pipe 2 is connected with reactor 3 by pipeline.The sidewall of described blending transportation pipe 2 is processed with charging aperture 5, and this charging aperture 5 is connected with storage tank 4 by pipeline, and this pipeline has valve 6, and storage tank 4 is positioned at the top of blending transportation pipe 2.The diameter of described blending transportation pipe 2 is first reduce gradually to increase gradually from its one end to the other end again, and the inlet diameter of blending transportation pipe 2 and discharging opening equal diameters.
During work, first the inlet of fluid delivery pump 1 is connected with water source by pipeline, then fluid delivery pump 1 is started, water is delivered in blending transportation pipe 2, then open valve 6, make the water-coal-slurry that in storage tank 4, concentration is higher enter into blending transportation pipe 2, the water-coal-slurry that then concentration is higher and water slowly mix while advancing in blending transportation pipe 2, obtain the water-coal-slurry of low concentration, the water-coal-slurry that final concentration is lower arrives in reactor 3 reacts.
