Problems solved by technology

This hanging method has a large number of hanging points and a large amount of work in the factory and on site. Since the hanging points are densely distributed at the elbow on the top of the superheater serpentine tube, the space above the superheater is limited, and the on-site working surface is easily affected. At the same time, it is also Not conducive to later maintenance
In addition, when the equipment is running, due to the high temperature of the working medium in the serpentine tube, there are relative displacements and deformations between the tubes, and the force on the hanging point at the elbow of the serpentine tube is uneven, and the problem of stress concentration is prone to occur, which affects the use of the superheater life

Embodiment Construction

[0018] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0019] Such as Figure 1-5 The shown superheater device with suspension structure includes the top beam frame 3 fixed on the furnace body frame of the waste incinerator, the horizontal flue fixed on the top beam frame through the suspension structure (omitted in the figure), and the horizontal flue positioned on the horizontal flue. Superheater in the tunnel:

[0020] The horizontal flue includes at least one group of horizontal flue headers, and each set of horizontal flue headers includes a horizontal flue upper header group 1-1, left and right side wall water walls 1-2 and a horizontal flue lower header Groups 1-3 are formed by welding the upper and lower header groups of the horizontal flue to the two ends of the left and right side wall water cooling walls respectively; the left and right side wall water cooling walls are spliced ​​by pipes and flat st...

Abstract

The invention relates to the field of waste incineration boilers. According to the overheater device with the suspension type structure for the garbage incinerator, the suspension type structure can remarkably reduce the number of suspension points of an overheater and reduce the welding operation amount, meanwhile, operation is convenient, the suspension structure is not prone to being affected by working media in a pipe and the temperature of smoke in a horizontal flue, the overheater is stressed more evenly, and the service life of the overheater is prolonged. And the problem of stress concentration is not easy to occur. According to the technical scheme, the superheater device with the suspension type structure is used for the garbage incinerator. Which comprises a top beam frame fixed on a garbage incinerator body frame, a horizontal flue fixed on the top beam frame and a superheater positioned in the horizontal flue, and is characterized in that the superheater is connected with the top beam frame through a suspension structure and is borne by the top beam frame; the suspension structure comprises a header and top beam grid suspension structure, a header and desuperheater connecting pipe suspension structure and a desuperheater connecting pipe and top beam grid suspension structure.

Description

technical field [0001] The invention relates to the field of waste incineration boilers, in particular to a superheater device with a suspended structure for waste incinerators. Background technique [0002] With the rapid development of the city, the problem of urban domestic waste is becoming more and more serious, among which waste incineration as a waste treatment method is conducive to the realization of harmless, reduction and resource utilization of urban domestic waste. With the change of people's living habits, the amount of garbage has increased year by year, and subsequently, the amount of garbage incineration has continued to increase, showing a trend of large-scale garbage incinerators. For example, a few years ago, the garbage disposal capacity of the garbage incineration boiler was ~500t / d, but now there are large-scale garbage incinerators with a capacity of 750t / d and above, or even 900t / d. [0003] Usually, large-scale waste incinerators generally adopt a ...
