Definitions
- the invention relates to a method for continuous Evaporation or for the thermal treatment of viscous viscous Products, especially elastomers and thermoplastics, in a mixing kneader with at least one with mixing or Kneading elements equipped stirrer shaft.
- the corresponding separation processes are usually in stirred heat exchangers and so-called mixing kneaders carried out in which the product by appropriate Kneading and transport elements from one inlet to one Transported and simultaneously with the Heat exchange surfaces are brought into intensive contact.
- mixing kneaders are, for example, in DE-PS 23 49 106, EP 0 517 068 A1 and DE 195 36 944 A1.
- the present invention is based on the object heat transfer limited section of the evaporation optimize.
- LIST-DTB mixer which is also used in the above mentioned DE-PS 23 49 106 is shown.
- the product is not only a mixer from inlet to outlet transported, but by backmixing with a new product homogeneously mixed again throughout the apparatus.
- the product is initially high in solvent still very liquid, so the evaporation takes place in the essentially about the contact heat coming from a heated Housing jacket, a heated shaft and / or heated Kneading counter elements comes.
- the method according to the invention also has the advantage that with the increased work intensity foaming, that of the flash dosage of the product in the Mixing kneader originates, is broken, whereby the Heat energy input is further improved.
- the for Evaporation required evaporation energy accordingly through the combination of contact heat and Maximized shear heat.
- the possibility of evaporation of solvent to keep the product temperature constant allows a high degree of freedom in relation to the Regulation of the shear heat via the speed (shear gradient) and the degree of filling of the mixing kneader.
- the product is in the downstream second mixer kneader by a corresponding geometry of the kneading elements Plug flow subjected.
- this second mixer kneader the evaporation limited by mass transfer takes place, which is why twin-screw mixers are preferred be under the name LIST-ORP (EP 0 517 068 A1) and LIST-CRP (DE 195 36 944 A1) are on the market.
- LIST-ORP EP 0 517 068 A1
- LIST-CRP DE 195 36 944 A1
- FIG 1 two mixing kneader 1 and 2 are together connected.
- the mixing kneader 1 is a Kneader with a good backmixing, as for example under the Designation LIST-DTB is on the market. On this DTB relates to DE-PS 23 49 106.
- a mixer kneader with good Backmixing is characterized in that the product in the entire mixing kneader is homogeneously mixed together.
- the mixer kneader 2 is one Kneader with a so-called plug flow, such as. is on the market under the name LIST-CRP or LIST-ORP.
- plug flow such as. is on the market under the name LIST-CRP or LIST-ORP.
- the corresponding property rights for this are in EP 0 517 068 and DE 195 36 944 A1.
- At a Mixing kneader with good plug flow is the product of Inlet transported to the outlet without an axial Mixing with the following product takes place. Therefore there is usually an inlet 3 for the Product at one end of the mixer kneader and an outlet 4, which in the present case as a discharge twin screw is formed at the other end of the mixer kneader 2.
- the mixer kneader 1 has an inlet 5 approximately in the center of the mixer and a discharge twin screw 6 at the end of the mixing kneader 1.
- each indicated two waves 7 and 8 or 9 and 10 which mixing, transport or kneading elements 11 are arranged are that rotate with the waves, like this among others in the above Property rights is described.
- a feed line 12 to the inlet 5 there is a pump 13, a heat exchanger 14 and a pressure holding valve 15 switched on.
- This referred to as a flash device Device preheats the product.
- a large part of the liquid is in the mixer kneader 1 Part of the product evaporated, the Mixing kneader 1 heat is supplied.
- a Housing shell 16 the kneader shafts 7 and 8 and the Kneading elements 11 are heated.
- the evaporated The component leaves the mixer kneader 1 via a vapor dome 17, with a corresponding derivative 18 Condenser 19 and an inert gas pump 20 turned on are.
- FIG. 2 also shows that the mixer kneader 1 can also have only one shaft 21.
- This mixer kneader 2 also has a dome 24, which merges into a derivative 25, into which a condenser 26 or an inert gas pump 27 are switched on.
- the kneading energy increases considerably due to the increasing viscosity of the product (up to 1300 Pas at 80 s -1 shear rate) without the contact heat transfer decreasing significantly. This means that a considerable amount of shear heat is added to the contact heat. At the same time, however, the solvent concentration is still high enough so that the entire energy input can be used to evaporate the solvent, so that the product temperature remains constant. This maximizes the effectiveness of the kneader in this area.
- this product behavior in the Mixing kneader 1 with good remixing exploited by the Concentration of solvent always around 25% Cyclohexane is kept. This is done via a controller the supply amount of fresh product and over a Regulation of the kneading energy by means of the shaft speed and the degree of filling.
- the solution so evaporated is by means of Discharge twin screw 6 from the mixer kneader 1 carried out continuously, simultaneously by shearing in warmed up the screw and into the mixer kneader 2 flashed.
- this mixer kneader 2 is a material transfer limited drying section carried out, where essentially no surface evaporation takes place. The evaporation points, the entirety of which so-called drying mirror, pull more and back to the good inside. The liquid must diffuse.
- the mixing kneader 2 is open for this process section Because of the shaft geometry and the kinematics with one maximum surface renewal, plug flow and good Product temperature control facility.
- the degassed elastomer is finally discharged from the mixing kneader 2 with the second discharge twin screw 4.
- the elastomer still contains a residual solvent content below 1000 ppm.
