Definitions
- the invention relates to a device for distribution and / or Smuggling a hot flour-like material, especially one hot cement raw meal stream in a plant for the production of Cement clinker made from raw cement meal in a heat exchanger system preheated and fired in a rotary kiln to cement clinker becomes.
- the distribution or conversion of the hot raw meal stream is previously accomplished with a distributor housing on the top the hot flour feed line and on the underside there are two hot flour feed lines are connectable so that the distributor housing from its shape is also referred to as a so-called "downpipe".
- a flap is pivotally arranged in the downpipe through which Swiveling the hot cement raw meal stream, which is a temperature from e.g. Can have 800 to 900 ° C, distributed or converted becomes. It goes without saying that the pivoting flap in particular exposed to high thermochemical and abrasive wear is.
- impact slides which in cement plants cross into one hot gas pipe coming from the rotary kiln and / or from the clinker cooler are installed and have the task of preheated raw cement meal, that is inserted into the hot gas line from the side is to distribute or evenly over the hot gas cross section suspend, are subject to high wear.
- Flap boxes or shuttle locks also double shuttle locks installed, in which one or two weight-loaded swing flaps are integrated, which have the task of the hot gas flow in each case withhold and on the other hand after a certain solid loading by swinging open the flaps the hot raw meal stream to let down through the flour fall pipe. Also these swing flaps are subject to high wear.
- the invention has for its object, in particular for cement plant construction for the distribution and / or smuggling of a hot flour-like Gutstromes to create a device, one internals subject to high wear, in particular the actuator, have a long service life.
- Characteristic of the distribution device according to the invention and / or transporting a hot flour-like material flow with swivel flap / pendulum flap or impact slider is that this organ particularly exposed to wear as a plate-shaped Hollow body through which cooling medium is formed, at least a cooling medium inlet opening and at least one cooling medium outlet opening having.
- a cooling medium is simplicity half of the outside air is used as cooling air by a cooling air fan or starting from a compressed air network connection the plate hollow body is pressed.
- the cooling medium cools the in the Rule made of metallic material hollow body flap or the hollow body impact slide and their surface. Solid caking on the cooled comparatively lightweight Organs according to the invention are avoided. All in all is the lifespan or the lifespan of the invention Hot flour distribution device or hot meal lock very high.
- the two-strand system for the production of cement clinker from raw cement flour 6 shows a left of the exhaust gas of a rotary kiln 10 flowed through strand and a right strand, the of hot radiator exhaust air via a tertiary air line 11 of the not shown Clinker cooler supplied with high-temperature cooler exhaust air becomes.
- Both strands each have cyclone floating gas preheater strands operated by themselves on, each for the sake of simplicity only the bottom two cyclone stages 12, 13 and 14, 15 are drawn are.
- Raw meal quantity can be on the left strand at 16 e.g. approx. 50% Raw flour and on the right strand at 17 also e.g. approx. 50% Quantity of raw flour to be abandoned.
- the Raw meal introduction point in the rotary kiln exhaust gas is located above an impact slide 19, which has the purpose of the introduced Distribute hot flour evenly across the rotary kiln exhaust gas cross-section.
- the flap 22 of the changeover box 21 switched and the hot flour of the left strand is via hot flour line 24 in the calciner 26 equipped with secondary firing 25 of the right strand into which the raw meal from the second lowest cyclone stage 14 of the right strand via line 27 also flows.
- the calcined in the Calinator 26 total cement raw meal in the bottom cyclone 15 of the right strand separated from the hot exhaust gas stream 28 and as high (e.g. 95%) calcined cement raw meal 29 introduced into the rotary kiln 10, in whose sintering zone is fired into cement clinker.
- the hot flour change box or distribution box 21 with the cooled Control flap 22 is drawn out in FIGS. 1 and 2.
- the flap 22, which can be pivoted about its underside, is through which the coolant flows Hollow body formed in the tubular housing 21 is arranged and, depending on the swivel position, the incoming hot meal stream 20 in one and / or other good derivation 23, 24 derives.
- the inside of the Hollow body flap 22 at least one arranged transversely to the flap plane Web 30 built into the one end of the hollow Valve shaft 31 supplied cooling medium, in the embodiment Cooling air, through the flap cavity to the other end of the hollow Valve shaft 31 for the purpose of extending the cooling air dwell time redirects.
- the cooling air conveyed by the cooling air fan 32 becomes inserted into one end of the hollow shaft 31 via a flexible line 33, and the cooling air heated in the flap 22 becomes over the other Blown end of the hollow shaft 31 via line 34 into the environment.
- the pivoting flap 22 is actuated via an adjustment drive 35, e.g. Electric actuator with motor 36 and articulated spindle 37, or via hydraulic swivel cylinders, pneumatic swivel cylinders etc.
- the impact slide 19 of FIG. 6 is drawn out in FIGS. 3 to 5.
- the impact slide is in FIG 19 from the right into rotary kiln exhaust gas riser 38 built-in.
- the hot flour introduced via the flour line 18 becomes in the event of an impact on the impact slide 19 of this evenly distributed the entire cross section of the rotary kiln exhaust gas riser.
- the impact slide 19 is also a hollow body through which cooling air flows formed, in the interior of which at least one transverse to the slide plane arranged web, in the exemplary embodiment according to FIG.
- two webs 39, 40 are installed, which over one the inlet opening 41 arranged on the outer slide face Cooling medium, cooling air again in the exemplary embodiment, for at least one also arranged on the outside of the slide face Coolant outlet opening, according to Figure 5 to the outlet openings Deflect 42 and 43.
- the through the opening 41 in the hollow body impact slide 19 introduced cooling air can high-speed compressed air be from their surroundings after the Injector principle further air volumes in the area in sucks the hollow body and through the hollow body to cool it promotes.
- the service life of the air-cooled impact slide 19 of the figure 3 is also very high.
- the air-cooled impact slide 19 can not only in the calcining zone the cement clinker production line, as shown in the example in FIG. 6, be installed, but also at another point in the cyclone suspended gas heat exchanger system, e.g. in the exhaust pipe between the bottom and the second bottom cyclone etc.
