Abstract
Provided is a tunnel kiln car using airflow bed reactor to discharge nitrogen and produce a product combining silicon nitride with silicon carbide. The kiln car is in a structure of four wheels. Each wheel is in a standard wheel structure of a common tramcar or a common tunnel kiln car. A car body is made of cast iron or steel. The top portion of the car body is identical with the tunnel kiln tunnel bottom line in height. Fire-proof and heat-insulation materials are constructed on the top portion of the car body in an erected mode so that sealing structures located at positions parallel to the tunnel kiln tunnel are formed. The intervals between the sealing structures range from 20 mm to 80 mm. Sand-holding disks are arranged on two sides of the car body, wherein the distance between each sand-holding disk and an inner side of each tunnel kiln framework vertical column ranges from 60 mm to 150 mm and each sand-holding disk is lower than the plane of a kiln car main body by 60 mm to120 mm. At the same time that a tunnel kiln is sealed, the gravity center of the kiln car is lowered. A sand-sealing device in which a plurality of sand-holding disks move is formed by metal strips installed at the bottom of the tunnel kiln together with the sand-holding disks, so that air in the kiln is prevented from leaking. Meanwhile, heat dissipated from the tunnel kiln is used to dry silica powder filter cakes. The total length of the tunnel kiln is integral times that of the kiln car.
