- European patent application EP 1 106 947 A1 describes a tunnel oven for the heating of printed circuit boards. This oven has inter alia two parallel conveyor belts for the printed circuit boards.
- Tunnel kilns are also used in the manufacture of autocatalysts for drying and calcining ceramic green bodies or a catalyst layer applied to inert carriers. Tunnel kilns for the calcination of ceramic honeycomb bodies are described, for example, in the patent documents US Pat. No. 6,048,199, US Pat. No. 6,089,860 and US Pat. No. 6,325,963 B1
- the present invention is particularly concerned with a tunnel kiln for the production of automotive exhaust catalysts.
- the goods are therefore preferably freshly coated with catalyst monolithic support body as they are used in the form of so-called honeycomb bodies made of ceramic or metal for the production of autocatalysts.
- the catalyst layer must be dried and calcined.
- the tunnel kiln according to the invention can also be used for the treatment of other goods.
- the catalytic coating of the honeycomb body usually consists of a slurry of oxidic carrier materials in water.
- the slurry may further contain precursor compounds of catalytically active noble metals and promoters. These are often nitrates or chlorides of these noble metals and promoters, which are converted into the actual catalytically active components only by the calcination in the tunnel kiln. By drying and calcination water vapor and nitrogen oxides or chlorine compounds are released, which must be discharged together with a part of the furnace air from the tunnel kiln with simultaneous replacement by fresh air and optionally fed to an exhaust gas detoxification.
- the honeycomb bodies From the loading station, the honeycomb bodies usually enter a drying zone in which they are dried at a temperature of about 100 to 200 ° C. After passing through the drying zone they enter the calcination zone in which they are treated at temperatures of 300 to 600 0 C. Then they leave the tunnel kiln via the unloading station.
- Object of the present invention is to provide a tunnel oven, which is particularly space-saving and optimally utilizes the heating energy used and thus contributes to energy savings.
- a tunnel furnace for the temperature treatment of goods (12, 12 ') which has a tunnel-shaped furnace space through which the goods to be treated are transported in a passage direction, wherein the tunnel kiln in the direction of passage a plurality of tunnel segments (10) flanged together. having.
- each tunnel segment contains at least one fan (15) and at least one heating element (17) and an intake duct (19) for fresh air and an exhaust duct (22) for exhaust air laden with exhaust gases and water vapor and in that / the fans in the tunnel segments are / are arranged in that it can generate a circulation flow (23) with a downward and an upward flow transversely to the direction of passage, two parallel conveyor belts (11, 11 ') being provided for the goods in the downward and upward flow.
- a circulation flow is generated transversely to the direction of passage of the goods in the tunnel segments of the blower or blowers and the goods to be treated are transported through the circulation flow both on the pressure and on the suction side of the blower.
- the generated gas stream is used optimally for the treatment of the goods.
- the downward or upward flow is on the pressure side or on the suction side of the fan or vice versa.
- the tunnel segments have a rectangular cross-section and are each bounded by a bottom, a ceiling and two side walls, the fans are preferably introduced from below through the bottom in the furnace chamber.
- the side walls of the tunnel segments can be designed hinged.
- flow guide plates and perforated or slotted plates for uniform arrival and optionally flow through the goods to be treated can be arranged to guide the air flow.
- the Strömungsleitbleche support the formation of the desired circulation flow.
- Both gas or oil burners or electric heating elements are suitable for heating the furnace space.
- electrical heating elements are used.
- the exhaust passage collects the exhaust air of the individual circulation flows and leads them outwards at a central point. If necessary, the exhaust air can be supplied to an exhaust gas detoxification.
- the fans located inside the tunnel segments must be serviced or repaired from time to time.
- the fans are flanged to the tunnel segment for the purpose of easy replacement with part of the floor or sidewall.
- cars or conveyor belts can be used.
- conveyor belts are used.
- the goods to be treated on the suction and pressure side of the blower on two parallel conveyor belts are transported by the circulation flows.
- both belts can be driven by a common drive.
- the tunnel kiln is used, for example, for the drying and calcining of catalyst layer coated ceramic or metallic honeycomb bodies for the production of autocatalysts.
- the desired temperature profile is set along the direction of passage of the tunnel kiln by controlling the heating elements of the tunnel segments.
- the goods to be treated are transported on the parallel conveyor belts by the downward and upward flow of the circulation flow, wherein each part of the circulation flow to remove released during the temperature treatment of the goods exhaust gases and steam is discharged from the oven and replaced by a corresponding amount of fresh air ,
- the modular design of the tunnel kiln makes it possible to insert other stations, such as a station for reductive treatment of the goods with, for example, forming gas, between the tunnel segments according to the invention. Furthermore, it is possible borrowed to replace the heating of a selected tunnel segments, if necessary, by cooling.
- the goods to be treated are only flowed through in one direction by the heating air.
- the return flow is guided around the goods on the outside.
- the individual tunnel segments must have a wider cross section than is necessary for the transport of the goods.
- the reverse flow of the circulatory Lungsströmung used for the treatment of goods can be designed correspondingly more compact.
- up to 30% lateral surface of a tunnel segment can be saved by the invention. This means a considerable saving in steel sheets and heat insulation.
- the heat radiation is reduced in accordance with the saved lateral surface, which can not be completely avoided despite good insulation.
- the tunnel kiln according to the invention thus also contributes significantly to the saving of energy.
- Figure 1 Side view of a tunnel kiln
- Figure 2 cross section through a tunnel segment
- Figure 1 shows the basic structure of a tunnel furnace (1).
- a loading station (2) for loading the tunnel kiln with the goods to be treated, or an unloading station (3) for removing the treated goods.
- the tunnel kiln consists of several flanged tunnel segments (4).
- temperatures between 100 and 600 preferably between 100 and 500 0 C are needed.
- the modular design of the furnace makes it possible to set the treatment temperature for each tunnel segment largely independently of neighboring segments. Thus, it is possible to then adjust the temperature in the oven for drying the wet catalysts between 100 and 200 0 C to the loading station. Only after passing through this drying zone, the furnace temperature is increased, for example, to 300 to 600 0 C, to calcine the catalyst coating.
- Figure 2 shows an example of the cross section of a tunnel segment (10) perpendicular to the direction of passage.
- the cross section of the tunnel segment is rectangular and is limited by a bottom plate (24), a ceiling (25) and by the two side walls (26 and 27).
- the cross section of the tunnel kiln is divided into two halves by a vertical flow baffle (13). In both halves is ever a conveyor belt (11, 11 ') for the goods to be transported through the tunnel (12, 12').
- the conveyor belts are expediently perforated to impede the circulation flow as little as possible.
- the longitudinal extent of the conveyor belts is directed perpendicular to the plane.
- a fan (15) is flanged from below to the tunnel furnace and serves to generate the circulation flow (23).
- the fan is driven by the motor (16).
- the gas flows in the tunnel segment are indicated in FIG. 2 by dashed arrows.
- On the suction side of the blower fresh air (18) via a suction passage (19) is sucked.
- the fresh air (20) is brought by a heating element (17) to the necessary treatment temperature.
- For cooling the fan motor it is advantageous to arrange the motor in the intake duct for the fresh air.
- the hot exhaust gas laden with exhaust gases (21) is collected by an exhaust gas duct (22) and led to a central disposal point.
- To use the heat content of the exhaust gas it is advantageous to lay the exhaust duct (22) in the interior of the tunnel segments.
- the flow conditions in the tunnel segment can be influenced by suitable Strömungsleitbleche and diaphragms so that the goods to be treated are flown as evenly as possible.
- suitable Strömungsleitbleche and diaphragms so that the goods to be treated are flown as evenly as possible.
- a further flow guide bleach (14) is shown in FIG.
- the necessary thermal insulation of the walls of the tunnel segment are not shown in Figure 2 for the sake of clarity.
