[0002] The glass kiln waste heat boiler is a device that uses the waste heat from the glass kiln to recover energy. During the glass production process, the glass kiln will generate a large amount of waste heat. If the waste heat from the kiln is not effectively utilized, it will not only cause waste of energy, but also have a negative impact on the environment. The problem of the glass kiln waste heat boiler solves this problem.

[0003] Common vertical glass kiln waste heat boilers are all suspended boilers. The boiler is composed of steel columns, beams, hangers, access platforms, internal heat exchange tubes, steam drums, steam-water pipes and other components. The boiler is supported by four full-length columns, and the cross beams on each layer of the boiler are welded to the columns. The internal heat exchange tubes of the boiler and some steel structures, shells and other accessories are connected by hangers. The top of the hanger is welded to the suspension beam or the large plate beam on the top of the boiler. The weight load of the lower part of the boiler acts on the hanger and the suspension beam. Suspended boilers have the advantages of free expansion, easy shockproof, and large bottom space for easy installation of ash removal equipment.

[0007] There are four bottom steel structure columns, which are respectively fixed on the ground by cement pouring. The four points connecting the fixed positions of the four bottom steel structure columns form a rectangle or a square.

[0008] The bottom steel plate and the bottom plate of the upper boiler frame are fixed together by edge welding, and the top plate and bottom plate between adjacent boiler frames are fixed together by edge welding.

[0009] One side of the support structure is a heating surface, and a plurality of tube row support beams are vertically fixed on the heating surface of the boiler frame, and tube row support sleeves are welded on the tube row support beams. The internal heat exchange tubes of the glass kiln waste heat boiler are placed in sections on the heating surface of the boiler frame and fixed on the support sleeves.

[0010] The top plate and the bottom plate of the heating surface area of ​​each layer of the boiler frame are hollow structures, so that the upper and lower adjacent heating surface areas are connected to each other.

[0011] A sealing plate covering the internal heat exchange tubes is arranged outside the heating surface of each layer of the boiler frame, and the sealing plate is welded to the top plate and the bottom plate.

[0012] X-shaped cross-welded reinforcing ribs are arranged between adjacent tube row support beams of the heating surface of each layer of the boiler frame.

[0019] The following is a further detailed description of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, etc., through the description of the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0020] This boiler has a bottom support structure. The boiler frame is stacked layer by layer. The internal heat exchange tubes are supported on the internal support beams through sleeve rings. This can greatly reduce the difficulty of boiler construction and installation and facilitate transportation. It can also reduce the floor space occupied by the boiler equipment accordingly, thereby reducing the initial investment cost of the boiler.

[0021] Specific structure such as Figure 1 As shown, the supporting structure of the waste heat boiler of the glass kiln does not adopt a top-down suspension structure, but is based on the bottom, and four bottoms fixed vertically on the ground are set on the ground; the bottom steel structure columns 1 can be equipped according to the scale of the upper building. Generally, four are set at the four corners and fixed on the ground by cement pouring. The four points of the four bottom steel structure columns 1 at the fixed positions form a rectangle or square. The bottom steel plate 2 is fixed on the top of the bottom steel structure column 1. The bottom steel plate 2 and the bottom steel structure column 1 form a bottom structure. The bottom steel plate 2 can be fixed on the bottom steel structure column 1 by welding. There are multiple layers of boiler frames stacked on top of the bottom structure. The supporting boiler frame adopts a layer-by-layer stacking form, which can greatly reduce the difficulty of boiler construction and installation and facilitate transportation. It can also reduce the floor area of ​​the boiler equipment accordingly, thereby reducing the initial investment cost of the boiler.

[0022] The structures of the multi-layer boiler frames are the same, all of which are composed of a top plate 4, a bottom plate 5, and frame columns 3 located at the four corners to support the top plate 4 and the bottom plate 5. The frame columns 3 are fixed to the top plate 4 and the bottom plate 5 by welding. The number of frame columns 3 is also set according to building requirements and can be set to be greater than four. The bottom steel plate 2 and the bottom plate 5 of the upper boiler frame are fixed together by edge welding. The top plate 4 and the bottom plate 5 between adjacent boiler frames are fixed together by edge welding to form a stacked and orderly multi-layer boiler frame.

[0023] One side of the supporting structure is the heating surface 6. The boiler is supported by short steel columns at the bottom. The internal heat exchange tubes are placed in sections in the outer shell of the boiler heating surface 6. Each outer shell of the heating surface 6 is manufactured in the boiler factory, shipped as a whole, and installed as a whole. The specific structure is that the boiler frame has multiple tube row support beams 7 vertically fixed on the heating surface 6. The top plate 4 and the bottom plate 5 in the area where the tube rows are arranged on the heating surface 6 are hollow structures, so that the upper and lower adjacent heating surface 6 areas are connected to each other. The tube row support beams 7 are fixed on the edge of the hollow area, and the tube row support rings 8 are welded on the tube row support beams 7. The internal heat exchange tubes of the glass kiln waste heat boiler are placed in sections on the heating surface 6 of the boiler frame and fixed on the support rings.

[0024] The heating surface 6 of each layer of boiler frame is provided with a sealing plate that covers the internal heat exchange tubes, and the sealing plate is welded to the top plate 4 and the bottom plate 5. That is, steel plates are installed between the outer shells of the heating surface 6 (the steel plates are only added around the box frame and do not block the flow of boiler flue gas), and the outer shells of adjacent heating surfaces 6 are welded to the intermediate sandwich steel plates. The internal heat exchange tubes of the boiler are equipped with a tube row support collar 8, which is welded to the support beam. X-shaped cross-welded reinforcing ribs 9 are provided between the adjacent tube row support beams 7 of the heating surface 6 of each layer of boiler frame to support the weight load on the upper part of the boiler.
