Definitions

  • the invention relates to a method for the efficient use of the hot air streams in a dryer system for dry goods, in particular for a vehicle painting plant, in which the exhaust air from the dryer is heated in a thermal post-combustion system and is passed as clean gas through Um Kunststoffrekuperatoren in which the circulating air taken from the dryer is heated up and returned to the dryer.
  • the freshly painted drying goods such as karts
  • a support frame in the dryer, wherein the organic solvents are in the fresh paint of the dry goods.
  • the Karrossen After heating in the heating zone of the dryer, for example, the Karrossen enter the holding zone of the dryer at about 140 ° C - 180 ° C. Then the karrossen leave the dryer.
  • exhaust air raw gas
  • TSV thermal afterburner
  • the exhaust air is preheated regularly in an exhaust air recuperator.
  • the clean gas from the post-combustion system initially cools down in the exhaust air recuperator and is then used to heat the dryer.
  • the invention has for its object to provide a method of the type mentioned, with a simple and reliable way ventilation of the locks is possible. Furthermore, a device should preferably be provided for carrying out the aforementioned method.
  • this object is achieved according to the invention by recirculating circulating air portions for ventilating inlet and / or outlet locks of the dryer from recirculating air recuperators to the dryer.
  • fresh air is not used directly for aeration of the locks. Rather, existing circulating air from the process itself is also used for the ventilation of the entrance lock and / or the exit lock.
  • This circulating air has been preheated in the circulating air recuperators, it is guided over already existing lines in the area of the dryer. Shares of this recirculation can are diverted from the direct introduction into the dryer and fed into the entrance lock and / or exit lock.
  • the circulating air components for the at least one lock are diverted from at least one section of the dryer adjacent to the lock of leading circulating air.
  • the circulating air led to this section of the dryer is dimensioned from the outset so that a portion for the lock can be taken from this circulating air. Removing the circulating air components from adjacent sections of the dryer further shortens the distances.
  • a throttling of the circulating air leading to the dryer and of the recirculating air component guided to a lock is made possible after their division and in each case independently of one another.
  • this throttling option is adjustable, how large the circulating air shares are, which are to be led to the lock. This can be adjusted to the conditions of the dryer suitable conditions of the locks.
  • At least one branch line is branched off from circulating air lines in operative connection with the recirculating air recuperators and routed to the inlet and / or outlet lock of the dryer.
  • the diversion of circulating air portions for the locks according to the method is carried out on the device side with corresponding branch lines.
  • These branch lines can be short, so that corresponding arming costs are low.
  • throttling elements can be inserted in the direction of flow of the circulating air after the branch of the branch line. With these, the individual lines can be adjusted in terms of their flow.
  • the dryer leading away recirculation line can open a fresh air line.
  • the introduced fresh air is then first fed to a recirculating air recuperator and then in the direction of the dryer.
  • the diverted from the recirculation line to the dryer circulating air component may then contain fresh air after this development.
  • the fresh air line can still be performed via a fresh air recuperator, the fresh air recuperator is in operative connection with a line for the clean gas.
  • the dryer 1 has an inlet lock 2, a heating zone 3, a holding zone 4 and an outlet lock 5.
  • the arrow 6 symbolizes the introduction of the dry goods, for example bodies, which are located on SKIDs. Of the Arrow 8 symbolizes the dry goods and SKIDs leaving the dryer.
  • the thermal afterburner TNV is designated 9.
  • 10 to 13 are circulating air recuperators. 13a is an exhaust recuperator and 15 is a fresh air recuperator. With 21 an exhaust chimney is called.
  • the arrow 22 indicates the supply of fresh air from the environment.
  • the exhaust ducts are at 18 and the circulating air lines are designated 17.
  • the the dryer 1 via the exhaust ducts 18 extracted exhaust gas (raw gas) is supplied via a fan unit 19 and the Ab povertyrekuperator 13 a of the TNV 9 and there subjected to the oxidation process.
  • the cleaned by the conversion exhaust air leaves the TNV 9 as clean gas in the clean gas line 20.
  • the clean gas is first passed through the Abluftrekuperator 13a, then through the Um Kunststoffrekuperatoren 10 to 13 and finally flows through the Frischluftrekuperator 15, whereupon it via the exhaust chimney 21 into the atmosphere exit.
  • flaps 26 are used. They correspond with flaps 25 in diversions 27 of the clean gas line 20.
  • the last Umluftrekuperator 13 is a bypass line 16 associated with a corresponding flap 26.
  • An auxiliary burner 14 acts via a line piece 22 on the clean gas line 20 a.
  • the auxiliary burner 14 is operated via a control line 23, this is linked to a temperature sensor 24 in the last Umluftrekuperator cycle.
  • the clean gas line 20 is connected to a return line 25 prior to entry into the last recirculating air recuperator 13.
  • the return line 25 leads back into the region of the auxiliary burner 14, where it is linked to the line piece 22.
  • a fan 27 is inserted in the return line 25 in the return line 25, a fan 27 is inserted.
  • the entrance lock 2 is adjacent to a heating zone 3.
  • the outlet lock 5 closest to is a holding zone 4. From leading into the heating zone 3 and in the holding zone 4 circulation lines 17 branch lines 28 are branched off. These lead into the entrance lock 2 and into the exit lock 5.
  • recirculation line 17 opens a fresh air line 30 a. This leads fresh air from the fresh air recuperator 15 in the recirculation line 17th
