Abstract

The utility model discloses a compensator special for waste heat power generation, which relates to the technical field of waste heat power generation compensators. The compensator comprises a first connecting pipe (1), a first corrugated pipe (5), flow guide pipes (6), a middle connecting pipe (7), a second corrugated pipe (8) and a second connecting pipe (9), wherein both ends of the first corrugated pipe (5) are respectively welded and fixed with the rear end outer wall of the first connecting pipe (1) and the front end outer wall of the middle connecting pipe (7); both ends of the second corrugated pipe (8) are respectively welded and fixed with the rear end outer wall of the middle connecting pipe (7) and the end part outer wall of the second connecting pipe (9); and the inner walls of the first corrugated pipe (5) and the second corrugated pipe (8) are both provided with the flow guide pipe (6). The structure of the compensator is scientific and reasonable, and a wear resistant thermal insulation material is additionally arranged on the inner wall, so that the inner wall is not easily worn and damaged; and the traditional single structure is changed, and a compound free type structure is adopted, so that a radial displacement and a angular displacement in a large range can be realized, and the service life is prolonged.

Description

The cogeneration dedicated compensator

Technical field:

The utility model relates to cogeneration compensator technical field, is specifically related to a kind of cogeneration dedicated compensator.

Background technique:

According to investigation, the waste heat total resources of every profession and trade account for the 17%-67% of its fuel consumption total amount, and the residual heat resources of recyclable utilization are about 60% of waste heat total resources.Utilize thermal power transfer unnecessary in the production process to be called cogeneration technology for the technology of electric energy, cogeneration is not only energy-conservation, also helps environmental protection.The visual plant of cogeneration is an exhaust heat boiler, and it utilizes heat or flammable matter in the working medium such as waste gas, waste liquid to make thermal source, produces steam and is used for generating.

Exhaust heat boiler is made up of drum, movable gas hood, fire door section flue, oblique 1 section flue, oblique 2 sections flues, the 1 section flue in end, the 2 sections flues in end, reinforced tube seat and suspension bracket etc.It is six circulation loops that exhaust heat boiler is divided into, and each circulation loop is made up of falling tube and asending pipe, because the pipeline in the exhaust heat boiler is many; For it is protected; Compensator is installed in the exhaust piping ingress usually, and the exhaust heat boiler body is protected in stretching of extraction duct.

Existing cogeneration compensator velocity of medium is too fast, easy to wear; And pipe temperature is too high, radial displacement is excessive, causes the cogeneration compensator fragile, and working life is short.

The model utility content:

The purpose of the utility model provides a kind of cogeneration dedicated compensator; It is scientific and reasonable for structure, sets up wear-resisting thermal-protective material at inwall, not easy to wear and damage; And change the single structure of tradition; Adopt compound free type structure, can realize large-scale radial displacement and angular displacement, prolonged working life.

In order to solve the existing problem of background technique; The utility model is to adopt following technological scheme: it comprises first and takes over 1, first bellows 5, honeycomb duct 6, middle adapter 7, second bellows 8 and second and take over 9; The two ends of first bellows 5 are fixed with the rear end outer wall of first adapter 1, the front end outer wall welding of middle adapter 7 respectively; To take over 9 end outer wall welding fixing with the rear end outer wall of middle adapter 7, second respectively at the two ends of second bellows 8, and the inwall of first bellows 5, second bellows 8 is provided with honeycomb duct 6.

The middle part outer wall of the middle part outer wall of described first adapter 1, the two ends outer wall of middle adapter 7, second adapter 9 all is welded with fagging 2, and is fixedly connected with pull bar 4 through nut 3 in twos between the fagging 2.

Described first takes over 1, first bellows 5, honeycomb duct 6, middle adapter 7, second bellows 8 and second takes over 9 inwall and is provided with wear-resisting thermal insulation ceramics material layer.

The utility model is scientific and reasonable for structure, sets up wear-resisting thermal-protective material at inwall, not easy to wear and damage, and change the single structure of tradition, and adopt compound free type structure, can realize large-scale radial displacement and angular displacement, prolonged working life.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Embodiment:

With reference to Fig. 1; This embodiment adopts following technological scheme: it comprises first and takes over 1, first bellows 5, honeycomb duct 6, middle adapter 7, second bellows 8 and second and take over 9; The two ends of first bellows 5 are fixed with the rear end outer wall of first adapter 1, the front end outer wall welding of middle adapter 7 respectively; To take over 9 end outer wall welding fixing with the rear end outer wall of middle adapter 7, second respectively at the two ends of second bellows 8, and the inwall of first bellows 5, second bellows 8 is provided with honeycomb duct 6.

This embodiment is scientific and reasonable for structure, sets up wear-resisting thermal-protective material at inwall, not easy to wear and damage, and change the single structure of tradition, and adopt compound free type structure, can realize large-scale radial displacement and angular displacement, prolonged working life.
