Description

A kind of rapid-cooling heat exchanger tube sheet heat insulation structural
Technical field
Heat-insulated and field of heat transfer is the utility model is related to, more particularly to a kind of rapid-cooling heat exchanger tube sheet heat insulation structural, is passed through To structure improvement come reduce tube sheet temperature, improve tube sheet service life reached extend rapid-cooling heat exchanger service life mesh 's.
Background technology
The cracking gas entrance tube sheet of conventional pyrolysis furnace rapid-cooling heat exchanger often leaks, and in heat exchanging process, splits Vent one's spleen direct contact protection plate, heat is directly passed to tube sheet, the temperature of tube sheet is raised quickly, in cracking gas by protection board When temperature is unstable, tube sheet is often in overtemperature state so that shell side side pipe plate produces high temperature corrosion with cooling water and causes to crack Stove blowing out.Find that entrance tube sheet water side corrosion is serious after disintegration rapid-cooling heat exchanger, pipe platform is thinned until perforation causes to leak.Through phase Analysis expert is closed, main cause is high temperature corrosion of the boiler water to tube sheet.
The content of the invention
The purpose of this utility model is to provide a kind of rapid-cooling heat exchanger tube sheet heat insulation structural, incited somebody to action in the cracking gas side of tube sheet Gap is reserved between protection board and tube sheet, and will be sealed up around protection board with ceramic fibre mat, make protection board and tube sheet it Between formed an air layer without flowing, to reduce the generation of heat transfer, so as to reduce the temperature of tube sheet.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rapid-cooling heat exchanger tube sheet heat insulation structural, including rapid-cooling heat exchanger and pyrolysis furnace, in the air inlet of rapid-cooling heat exchanger Mouth end and outlet port are respectively arranged with tube sheet, and rapid-cooling heat exchanger internal heat exchange tubes are fixed on the side pipe plate of both ends, inlet port Tube sheet is connected with pyrolysis furnace cracking gas bobbin carriage lining end face seal, and rapid-cooling heat exchanger inner close fitting heat exchanger tube lateral wall is provided with ventilation Road, ventilating duct connect with pyrolysis furnace cracking gas bobbin carriage, and being connected side end face with pyrolysis furnace cracking gas bobbin carriage lining in the tube sheet sets Metallic packing is equipped with, protection board is provided with the outside of metallic packing, wherein, it is provided with protective case on the tube sheet Pipe, protection sleeve pipe connect the ventilating duct in rapid-cooling heat exchanger with pyrolysis furnace cracking gas bobbin carriage, and protection sleeve pipe penetrates metal sealing Pad and protection board are tightly connected with metallic packing and protection board, between being provided between protection board and metallic packing Gap.
Scheme is further:Gap between the protection board and metallic packing is not less than 10mm.
Scheme is further:Pottery is provided between the pyrolysis furnace cracking gas bobbin carriage lining end face and metallic packing Porcelain fibrous encapsulation heat insulating mattress, the inner side end of ceramic fibre sealing heat insulating mattress extend to protection board end face side and metallic packing Between gap in.
Scheme is further:The overlay cladding that gap between protection board end face side and metallic packing passes through setting Sealing.
Advantageous effects of the present utility model are:Between being reserved in the cracking gas side of tube sheet between protection board and tube sheet Gap, and will be sealed up around protection board with ceramic fibre mat, make to form an air without flowing between protection board and tube sheet Layer, to reduce the generation of heat transfer, so as to reduce the temperature of tube sheet.The improvement of this heat transfer structure will effectively reduce the temperature of tube sheet Degree, avoid tube sheet water side and the temperature range of high temperature corrosion occur, improve tube sheet service life, this structural approach can also be generalized to On similar devices.
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
A kind of rapid-cooling heat exchanger tube sheet heat insulation structural, including rapid-cooling heat exchanger and pyrolysis furnace, Fig. 1 illustrate rapid-cooling heat exchanger The pyrolysis furnace cracking gas bobbin carriage 1 and rapid-cooling heat exchanger inlet port 2 being connected with each other with pyrolysis furnace, in the air inlet of rapid-cooling heat exchanger End and outlet port are respectively arranged with tube sheet 3, and rapid-cooling heat exchanger internal heat exchange tubes 4 are fixed on the side pipe plate of both ends, inlet port Tube sheet is connected with the end face seal of pyrolysis furnace cracking gas bobbin carriage lining 101, and rapid-cooling heat exchanger inner close fitting heat exchanger tube lateral wall is provided with Ventilating duct 5, ventilating duct are connected with pyrolysis furnace cracking gas bobbin carriage, and side is connected with pyrolysis furnace cracking gas bobbin carriage lining in the tube sheet Face is provided with metallic packing 6, and protection board 7 is provided with the outside of metallic packing, wherein, it is provided with the tube sheet Protection sleeve pipe 8, protection sleeve pipe connect the ventilating duct in rapid-cooling heat exchanger with pyrolysis furnace cracking gas bobbin carriage, and protection sleeve pipe penetrates gold Belong to gasket seal and protection board to be tightly connected with metallic packing and protection board, set between protection board and metallic packing It is equipped with heat-insulated gap 9.Wherein, the gap between the protection board and metallic packing is not less than 10mm, typically 10 to Between 20mm.
In embodiment:Ceramic fibre is provided between the pyrolysis furnace cracking gas bobbin carriage lining end face and metallic packing Dimension sealing heat insulating mattress 10, the inner side end of ceramic fibre sealing heat insulating mattress extend to protection board end face side and metallic packing it Between gap in.
Wherein:Gap between protection board end face side and metallic packing seals 11 by the overlay cladding of setting.
It is quencher bobbin carriage and tube sheet contact site shown in Fig. 1.Left side conical section is cracking gas side pipe case, in bobbin carriage There is lining 101 to be incubated, there is protection board to carry out sealing by metallic gasket 6 between bobbin carriage and tube sheet and be close on tube sheet, bobbin carriage Heat-insulated with ceramic fibre mat 10 between lining end face and metallic gasket 6, tube sheet uses butt welding with heat exchanger tube.Bobbin carriage cracking gas from Bobbin carriage entrance enters, and after tube sheet and heat exchanger tube carry out heat exchange with shell side, is flowed out from cold end bobbin carriage.In metallic gasket with protecting Increase heat-insulated gap 9 between backplate, while increase protection sleeve pipe 8 on protection board, insert the cannula into tube sheet.To ensure to protect The gap of plate and metallic gasket and tube sheet, protection board is fixed by bolts on tube sheet, is entered among end using ceramic fibre mat Row is heat-insulated.This mode can make to form an air layer without flowing between protection board and tube sheet, to reduce heat transfer Produce, so as to reduce the temperature of tube sheet, and then reduce the generation of corrosion.
