Abstract

The utility model relates to an indirectly heating high temp radiation tube, comprising an outer tube, an inner tube, a mixer, a nozzle, a heat exchanger and an air pipe. The utility model is made of ceramic material. The connecting position of the inner tube and the mixer forms a taper shape, and the inner tube and the mixer are sheathed and connected. The outer circumference of the inner tube is provided with a plurality of register pins. The utility model can bear higher temperature and also has the advantages of long service life and low cost.

Description

Indirectly heating high temp radiation tube

The utility model relates to the improvement of indirect hyperthermia radiation pipe.

Indirect hyperthermia radiation pipe generally is made up of outer tube, interior pipe, blender, jet pipe, heat exchanger and wind cover, during use, the combustion gas that enters from jet pipe mixes after-combustion with the hot-air that enters from the jet pipe periphery blender, in interior pipe, form long flame, the flue gas that produces is through the space between interior pipe and the outer tube, and the heating outer tube passes through heat exchanger again, with the combustion air preheating, discharge from wind cover side pipe at last.At present, outer, the interior pipe of radiant tube all adopt heat resisting steel to make, and serviceability temperature is below 950 ℃, and therefore, directly the interior pipe that contacts with flame is easy to deformed damaged, has also limited the raising of serviceability temperature simultaneously, can not satisfy the technological requirement of high temperature furnace.

The purpose of this utility model is to propose a kind of indirect hyperthermia radiation pipe that can bear higher temperature.

Technical solution adopted in the utility model is: interior pipe adopts ceramic material, and the junction of interior pipe and blender is taper, and both sockets are provided with a plurality of locating pins on the outer circumference surface of interior pipe.

Fig. 1 is a configuration diagram of the present utility model;

Fig. 2 is interior pipe and the diagrammatic sketch that is connected of blender.

The utility model is made up of outer tube (1), interior pipe (2), blender (3), jet pipe (4), heat exchanger (5) and wind cover (6), outer tube (1) still adopts heat resisting steel, to keep high strength, be convenient to carrying and mounting or dismounting, interior pipe (2) adopts ceramic material, can bear 1500 ℃ high temperature, the junction of interior pipe (2) and blender (3) is taper, both sockets, so both can avoid producing thermal stress, pipe changes and good airproof performance in being convenient to again, is provided with a plurality of locating pins (7) on the outer circumference surface of interior pipe (2), the location of pipe in guaranteeing.

The advantage that the utility model uses under having high temperature and the operating period is long, cost is low, its inner tube also has and does not at high temperature also reduce intensity, indeformable, advantage that corrosion resistance is good.

Claims

A kind of indirect hyperthermia radiation pipe, comprise outer tube (1), interior pipe (2), blender (3), jet pipe (4), heat exchanger (5) and wind cover (6), it is characterized in that: interior pipe (2) adopts the junction of managing (2) and blender (3) in the ceramic material to be taper, both sockets are provided with a plurality of locating pins (7) on the outer circumference surface of interior pipe (2).
