Detailed Description

For the convenience of understanding, the technical solution of the present invention is further described in detail below by way of embodiments with reference to the accompanying drawings:

as shown in fig. 1-5, a novel muffle furnace tube port cooling device comprises a muffle tube 1, a seamless tube 2, a first flange 3, a second flange 4, a third flange 5, a downcomer 6, a base 7, an elbow 8, a mouthpiece 12 and a cooling device.

The seamless pipe 2 is located the muffle pipe 1 and is close to the upper side of the high-temperature zone end, and is fixed on the upper side of the muffle pipe 1 in a welding mode, and the seamless pipe 2 extends into the muffle pipe 1.

The muffle tube 1 is made of a centrifugally cast heat-resistant alloy tube, preferably RA330, which has good high-temperature resistance and high-temperature creep resistance. The cooling device is welded on the outer side of the tube wall of the muffle tube 1, the cooling device comprises a first cold water tube 9, a second cold water tube 10 and a third cold water tube 11, the first cold water tube 9, the second cold water tube 10 and the third cold water tube 11 are respectively fixed on the outer side of the tube wall of the muffle tube 1, the first cold water tube 9 is positioned on one side of the seamless tube 2 close to high temperature, the first cold water tube 9 is fixed on the muffle tube 1 in a semicircular shape in a welding mode, the second cold water tube 10 is positioned below the seamless tube 2,
