Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: the superheater, including first main part pipe 3, the one end of first main part pipe is through sleeve pipe 6 respectively the first body 1 of fixedly connected with and second body 2, the inside embedding of first body 1 and second body 2 has built-in protection tile 301, the inboard fixedly connected with mount 7 of first body 1 and

second body

2, 6 fixedly connected with second main part pipe 4 of sleeve pipe is passed through to the one end of first main part pipe, 6 fixedly connected with third main part pipe 5 of sleeve pipe is passed through to the one end of second main part pipe 4, comb plate 9 on the top fixedly connected with of first body 1, comb plate 10 under the bottom fixedly connected with of first body 1, first body 1 is through last comb plate 9 and comb plate 10 fixedly connected with abrasionproof cover 8 down, the outside swing joint of abrasionproof cover 8 has abrasionproof apron 11.

In this embodiment, specifically, first body 1 and second body 2 are formed by mild steel material processing, and the inside fretwork of first body 1 and second body 2, first body 1 and second body 2 and sleeve 6 fixed connection, first body 1 and second body 2 are formed by mild steel material processing, and are sturdy and durable more.

In this embodiment, specifically, the first main pipe 3, the second main pipe 4 and the third main pipe 5 are all in a serpentine shape, the outer surfaces of the first main pipe 3, the second main pipe 4 and the third main pipe 5 are smooth, the first main pipe 3, the second main pipe 4 and the third main pipe 5 are all fixedly connected through the sleeve 6, and the first main pipe 3, the second main pipe 4 and the third main pipe 5 are all in a serpentine shape, so that the high-pressure wet steam can be better heated to be changed into dry steam.

In this embodiment, specifically, the diameter of the internal protective tile 301 is matched with the inner diameters of the first tube 1 and the second tube 2, the first tube 1 and the second tube 2 are fixedly connected with the internal protective tile 301, because the internal protective tile 3 is attached to the inner walls of the first tube 1 and the second tube 2, and the internal protective tile 3 is made of clay, the first tube 1 and the second tube 2 on the superheater can not burst due to pressure when high-pressure wet steam flows through,
