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

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.
