Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to the drawings, the combined type heat tracing instrument box for the polar region environment comprises an instrument box 4, wherein the instrument box 4 comprises a box body 401, a mounting hole is formed in the top wall of the box body 401, and a fan heater 1 is fixed in the mounting hole. A door 403 is connected to the front wall of the cabinet 401.

The three inside walls of the box body 401 are respectively connected with S-shaped steam coil pipes 402, an upper end pipe orifice of each S-shaped steam coil pipe penetrates through the top surface of the box body 401 and is connected with an inlet of the steam confluence pipe 2, a lower end pipe orifice of each S-shaped steam coil pipe 402 penetrates through the bottom surface of the box body 401 and is connected with an outlet of the steam diversion pipe 7, the condensate recoverer 8 comprises a shell, a steam outlet and a steam inlet are respectively formed in the top surface and the bottom wall of the shell, and a water outlet is formed in one side of the condensate recoverer 8. The inlet of the steam shunt pipe 7 is connected with the steam outlet of the condensed water recoverer 8 through a steam inlet pipe.

Preferably, the box 401 is a jacket composed of an inner shell and an outer shell, the jacket is filled with heat insulation materials, preferably, an inclined steel plate is welded on the bottom wall in the condensate water recoverer 8 to enable condensate water to flow out along the steel plate, and the water outlet is located on the water flow outflow side of the steel plate.
