The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the utility model, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the present utility model. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.

The relative arrangement of the components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present utility model unless it is specifically stated otherwise. Meanwhile, it should be clear that the dimensions of the respective parts shown in the drawings are not drawn in actual scale for convenience of description. Techniques, methods, and apparatus known to one of ordinary skill in the relevant art may not be discussed in detail, but should be considered part of the specification where appropriate. In all examples shown and discussed herein, any specific values should be construed as merely illustrative, and not a limitation. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.

In the description of the present utility model, it should be understood that the azimuth or positional relationships indicated by the azimuth terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal", and "top, bottom", etc., are generally based on the azimuth or positional relationships shown in the drawings, merely to facilitate description of the present utility model and simplify the description, and these azimuth terms do not indicate and imply that the apparatus or elements referred to must have a specific azimuth or be constructed and operated in a specific azimuth, and thus should not be construed as limiting the scope of protection of the present utility model: the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In addition, the terms "first", "second", etc. are used to define the components, and are only for convenience of distinguishing the corresponding components, and the terms have no special meaning unless otherwise stated, and therefore should not be construed as limiting the scope of the present utility model.

The utility model provides a technical scheme that: 1-4, including outer tube 1 and inner tube 2, the one end of outer tube 1 is connected and is burnt burning furnace outer wall 3 and communicates with each other with burning furnace outer wall 3, the other end of outer tube 1 links to each other with first ball valve 4, part of inner tube 2 sets up inside outer tube 1, another part of inner tube 2 sets up inside burning furnace and is provided with nozzle 5 at the tip, the other end of outer tube 1 links to each other with first ball valve 4, the other end of first ball valve 4 links to each other with return bend 6, the other end of return bend 6 links to each other with second ball valve 7, the other end of second ball valve 7 links to each other with air inlet duct 8.

A gap is arranged between the outer tube 1 and the inner tube 2. The side wall of the outer tube 1 is communicated with a compressed air tube 9. The compressed air pipe 9 cools, so that the high temperature of the components outside the furnace caused by the outward transfer of the internal temperature of the furnace chamber is reduced as much as possible, and the compressed air is directly communicated with the furnace chamber.

The first ball valve 4 is respectively connected with the outer pipe 1 and the elbow pipe 6 through bolts by a flange pad 10. The second ball valve 7 is respectively connected with the elbow 6 and the air inlet pipeline 8 through bolts by a flange pad 10.

The working process of the utility model is as follows: when the condition is replaced, the front-end system can be stopped briefly through the second ball valve 7, the air inlet pipeline 8 is replaced and cleaned, and sampling is qualified; and disassembling bolts of flange gaskets between the bent pipe 6 and the first ball valve 4, and pumping the inner pipe 2 inside the first ball valve 4 to enable the whole inner pipe 2 to be pulled out of the first ball valve 4, so that the burner 5 is pulled out.

After the burner 5 is extracted from the first ball valve 4, the first ball valve 4 is closed to prevent flame from overflowing; the new burner 5 is replaced by the old burner 5, the inner pipe 2 is inserted into the first ball valve 4, after the burner 5 reaches the valve core of the first ball valve 4, the first ball valve 4 is slowly opened, the burner 5 is gradually sent into a furnace body through the inner pipe 2, and after the burner 5 reaches a preset position, bolts of flange gaskets between the bent pipe 6 and the first ball valve 4 are installed; leak testing the flange mouth; after the leakage test reaches the requirement, the second ball valve 7 is opened, and the gas is continuously fed to finish the replacement; in areas of complex structure, the bent pipe 6 may use a metal hose instead of a hard steel pipe.

It should be noted that the first ball valve 4 needs to be sealed by steel, and plastic or other materials with poor temperature resistance should be avoided for sealing; during the replacement, the gas is required to be stopped briefly, and the gas can be replaced after stopping; if the pipeline between the second ball valve 7 and the first ball valve 4 is required to be cleaned, replaced and sampled before being replaced, the replacement operation can be performed; in the process of replacing the burner 5, the burner needs to be matched, so that the flame in the incinerator is prevented from channeling outwards; during replacement, fire in the furnace end area should be avoided as much as possible, and the furnace nozzle 5 should be prefabricated in advance.

The foregoing is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical scheme of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
