Definitions
- the present invention relates to a homogenizer and its use.
- a homogenizer is known from German utility model G 8912938.5. This comprises a stator, a rotor and a shaft receiving the rotor.
- the stator and rotor are cylindrical and their surfaces facing each other are parallel to the shaft, ie axially
- the homogenizer is said to be suitable for producing an emulsion of diesel fuel and water, the particle size of which does not exceed 1 ⁇ m and which has a service life of approximately 10 minutes.
- the present invention is therefore based on the object of providing a homogenizer with which a
- Diesel fuel water emulsion can be produced without such disadvantages.
- the width of the grooves and webs are mounted transversely to the shaft, ie radially.
- Grinding gap between stator and rotor is preferably constant.
- the constant width can be set as required.
- Rotors in the range customary for rotors of homogenizers preferably in the range of 2500-5000 rpm.
- the shaft exiting on one side is sealed with a sealing ring which is reinforced on the unpressurized side by a Teflon ring.
- the adjoining surfaces of the Simmerring and the Teflon ring are preferably matched to one another
- the homogenizer has one or more, preferably two, feed lines for the substances to be introduced.
- the homogenizer according to the invention is suitable for the following reasons.
- the water content can be selected depending on the diesel fuel used, preferably it is 10-20%, based on the total volume of the emulsion.
- To produce such a diesel fuel and water are introduced into the homogenizer under pressure in the range of 0.25 bar to 25 bar.
- the emulsion obtained then has one
- Particle size from l ⁇ im and smaller Particle size from l ⁇ im and smaller. Their service life is approx. 8 minutes. It has been shown that the service life of the emulsion can be extended to several days if a surfactant, preferably with an HLB value of about 8, is added to the emulsion or already when the emulsion is being prepared in the homogenizer.
- the amount of the surfactant is advantageously 0.1-1%, based on the total volume of the emulsion.
- a similar extension of the service life of the emulsion is achieved if the biocatalyst is used instead of the surfactant
- An emulsion produced according to the invention can be any commercially available ion stabilizer.
- An emulsion produced according to the invention can be any commercially available ion stabilizer.
- the homogenizer according to the invention can be attached directly to the engine of the diesel motor vehicle. It is also suitable for installation in boiler combustion plants. It is also used in all areas where long-term emulsions or suspensions are required, such as in the manufacture of cosmetics, pharmaceuticals and food. In addition, it should be noted that it is the
- the homogenizer according to the invention makes it possible to convert diesel fuel into a form even without the addition of water, the combustion and emission values of which are favorable.
- An embodiment of the homogenizer according to the invention is shown in the accompanying figures. It shows
- Figure 1 is an overview drawing of the homogenizer, Figure 2 the stator with surface structure Figure 3 the rotor with surface structure, Figure 4 flange, inlet side and
- Figure 5 Flange, outlet side.
