Description
A device for administration of compressible materials into pneumatic transport system namely pipeline, the method of such administration to transport material, compression and usage
Technical field
The invention deals with a device, which allows administering compressible materials with low mass usually in the range of 30-300kg/m3 into pneumatic transport pipeline.
Background Art
When administering some very light materials with mass usually in the range of 30-300kg/m3, such as various types of solid alternative fuels (by solid alternative fuels it is meant fuels made of solid industrial and domestic waste which can substitute standard fuels based on gas, oil and coal) used in cement factories, lime-kilns, power-engineering into pneumatic transport pipeline, these are often obstructed and blocked when using standard feed device, such as revolving feed. Backlash from pneumatic transport pipeline through revolving feed, which cannot be eliminated in any way, works against the motion of the material entering the funnel of revolving feed thus lowering the maximum reachable effect of the feed. These materials also often form clusters, which cause uneven flow through all ordinary feed devices, also causing uneven feed into pneumatic transport pipeline into subsequent technological procedure. This uneven flow of material leads, especially with pneumatic transport of material (fuel) into combustion procedure, to its instability.
Disclosure of the technical solution
These disadvantages are largely eliminated by the device according to this invention for administration of compressible material with a mass usually in the range of 30-300kg/m3 into pneumatic transport pipeline comprising helical indenting conveyer, compression chamber and pneumatic transport pipeline equipped with a nozzle - ejector. The essence of the invention lies in that the material designated for transport using pneumatic transport pipeline is appropriately fed to the funnel of helical conveyer, through which it is indented into conical compression chamber, where due to reduced transport opening it is being compressed. Once compressed it is indented into pneumatic transport pipeline. After indenting of the material into pneumatic transport pipeline the compressed material is then loosened by enlarging the transport opening and subsequently by an air current with a speed of 100-300 m/s created by circular slot nozzle - ejector, which is located and shaped so that the air current evenly cuts the material indented into the transport pipeline. Individual particles of compressed material are immediately after indenting separated and carried away by pneumatic transport pipeline. Dramatic acceleration of air current to a speed of 100-300 m/s in the nozzle leads, based on Bernoulli equation (ejector principle) , to a subsequent decreasing of air pressure at the area of loosening (input) fed material to a transport pipeline. Thus the pressure difference between the input of fed material into pneumatic transport pipeline and a place of input of material into the nozzle of the helical conveyer is lowered and also the backlash of transporting air from transport pipeline through helical indenting conveyer into the funnel is lowered.
Technological procedure of the invention comprises the following stages in individual steps:
1.1st stage - compression
Indenting material into conical compression chamber uses conical shape of compression chamber and indenting conveyer, where due to reducing the opening the material is compressed
2. 2nd stage- feeding
Feeding of compressed material into pneumatic transport pipeline from output compression chamber.
3. 3rd stage
Loosening of compressed material after its indenting into pneumatic transport pipeline using the air current with high speed of 100-300 m/s and transport.
Advantages or disadvantaged of the invention
An advantage of the invention is a possibility to indent large volume of fed material into pneumatic transport pipeline and its subsequent loosening by air current with high speed (see the above definition) and thus creating a homogenous current of a mixture of fed material and air in transport pipeline which allows its optimal transport and further optimal use in consequent technological procedure (for example of in the procedure of combustion) . Compressed material in the compression chamber also forms a seal and prevents the backlash from the pneumatic transport pipeline into helical conveyer and its funnel. Air current of high speed created by a nozzle - ejector for loosening the indented material, also in the area of feeding (behind the nozzle) dramatically lowers the overpressure in the pneumatic transport pipeline, what also helps to indent the material into pneumatic transport pipeline and lowers the backlash from pneumatic transport pipeline into helical indenting conveyer and its nozzle.
