Abstract
The utility model relates to a flue gas sealing baffle plate between pressure part modules of a waste heat boiler. The utility model is characterized in that flue gas sealing baffle plate comprises a horizontal sealing baffle plate fixed between the pressure part modules, wherein the horizontal sealing baffle plate is fixedly connected with a vertical baffle plate, the bottom of the vertical baffle plate is arranged in a lower limit stop, the lower limit stop is arranged on a wall board, and the lower limit stop, the vertical baffle plate and the wall board are not fixed. The flue gas sealing baffle plate has the advantages that the vertical baffle plate is supported by the horizontal sealing baffle plate, so the boiler is not easy to distort in the operation; the lower limit stop, the vertical baffle plate and the wall board are not fixed, thereby being favorable for the vertical battle plate to expand all around; the upper limit stop is removed, and the vertical baffle plate can be thinned, thereby saving the material; the boiler manufacture and installation are convenient.
Description
Technical field
The utility model relates to a kind of waste heat boiler pressure containing part intermodule flue gas seal diaphragm, is used for preventing that the heat transfer space that flue gas flow direction pressure containing part module is formed from flowing outward, to reduce thermal losses, improves boiler efficiency.
Background technology
Waste heat boiler pressure containing part intermodule flue gas seal diaphragm uses in waste heat boiler extensively, in waste heat boiler body flue, near flue top and the pressure containing part module of bottom and the exhaust gases passes that the flue side wall has been formed a sealing, flue gas carries out heat exchange with extended surface tube in heat transfer space respectively.Owing between the pressure containing part module space is arranged, therefore needs between the pressure containing part module, to be provided with the flue gas seal diaphragm and prevent that the breach of flue gas between module from flowing out.
Existing flue gas seal diaphragm is made up of horizontal baffle and vertical partition plate, vertical partition plate is fixed on block and the following block, last block is fixed on the horizontal baffle, following block is fixed on the wallboard of bottom, vertical partition plate and last block and following block are all unfixing, to absorb the displacement all around between pressure containing part module and the wallboard.Be in operation, because vertical partition plate is flexible the connection with upper and lower block, and vertical partition plate is than higher, and its top gravity is born by the bottom, in the operation back easy deformation of being heated, thereby is unfavorable for isolated both sides flow of flue gas.
Summary of the invention
The purpose of this utility model provides a kind of waste heat boiler pressure containing part intermodule flue gas seal diaphragm that is difficult for thermal deformation.
In order to achieve the above object, the utility model provides a kind of waste heat boiler pressure containing part intermodule flue gas seal diaphragm, it is characterized in that, comprise the horizontal seal dividing plate that is fixed between the pressure containing part module, the horizontal seal dividing plate is fixedlyed connected with vertical partition plate, the bottom of vertical partition plate is located at down in the block, and following block is located on the wallboard, and is all unfixing between following block and vertical partition plate and the wallboard.
Distance between the inboard diapire of the bottom of vertical partition plate and following block is 50-300mm.
The utility model has the advantages that:
1, vertical partition plate is not easy distortion by the horizontal seal membrane support during boiler operatiopn.
2, block and vertical partition plate and wallboard are all unfixing down, help the expansion all around of vertical partition plate.
3, removed last block, but and the vertical partition plate attenuation, material saved.
4, make things convenient for the boiler manufacturing to install.
Description of drawings
Fig. 1 is a waste heat boiler pressure containing part intermodule flue gas seal diaphragm structural representation.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be waste heat boiler pressure containing part intermodule flue gas seal diaphragm structural representation.Described waste heat boiler pressure containing part intermodule flue gas seal diaphragm is made up of horizontal seal dividing plate 1, vertical partition plate 2 and lower baffle plate 3.Horizontal seal dividing plate 1 is fixedlyed connected with vertical partition plate 2, insert in the following block 3 bottom of vertical partition plate 2, distance between the bottom of vertical partition plate 2 and the following block 3 inboard diapires is 200mm, and following block 3 is located on the wallboard 5, and is all unfixing between following block 3 and vertical partition plate 2 and the wallboard 5.
Because there is certain distance vertical partition plate 2 bottoms with following block 3 bottoms, vertical partition plate 2 expands downwards when helping the waste heat boiler operation like this; Following block 3 is not fixedlyed connected with the wallboard 5 of bottom, and following block 3 can be with vertical partition plate 2 move left and right.In addition, because vertical partition plate 2 bears gravity without self, its variable thickness is thin.
Claims (2)
