Problems solved by technology
Heat exchange with the same power saves consumables, but the manufacture is complicated and maintenance is inconvenient
According to the applicant's understanding, due to the limitation of its own structure, it is difficult to adopt the necessary cooling structure (especially the tubular type), and the general steel is close to its own melting point at about 1000 ° C, so when the temperature of the heat exchange medium reaches about 1000 ° C, this Both heat exchangers are overwhelmed and cannot work continuously

Embodiment 1
[0017] The high temperature heat exchanger of this embodiment is as Figure 1 to Figure 4 As shown, the middle part of the shell of the tank-shaped shell 1 is divided into a high-temperature chamber 3 and an air outlet chamber 4 by a partition 2, and the upper part has a crown return chamber 5 located in the shell. The high temperature chamber 3 is provided with a high temperature medium inlet 6, and the air outlet chamber 4 is provided with a high temperature medium outlet 7. The inner walls of the high-temperature chamber 3 and the high-temperature medium inlet 6 are lined with refractory bricks as a heat insulation layer, so as to prevent the high-temperature gas from directly contacting the steel body of the heat exchanger. The top communicates with the return cavity 5 through the first set of vertical tubes 8 . The high temperature chamber 3 has an inclined deflector 11 from the high temperature medium inlet 6 to the lower end of the first group of tubes 8 . The return ...

The invention relates to a high temperature heat exchanger, belonging to the technical field of heat exchanging facilities. The heat exchanger is provided with a pot-shaped shell, the central part of the shell is divided into a high temperature cavity and an air outlet cavity by a partition board, and the upper part of the shell is provided with a coronary backflow cavity located in the shell. The high temperature cavity is provided with a high temperature medium inlet, and the air outlet cavity is provided with a high temperature medium outlet. The inner wall of the high temperature cavity is lined with a thermal insulating layer, and the top of the high temperature cavity is communicated with the backflow cavity through a first group of tube array; the backflow cavity is communicated with the air outlet cavity through a second group of tube array; the middle part of the shell is provided with a peripheral layer to form an interlayer cabin; the peripheral layer is provided with a cold air inlet, and the upper part of the interlayer cabin is communicated with an upper cavity chamber formed between the upper part of the shell and the coronary backflow cavity; and the upper cavity chamber is provided with a hot air outlet. The heat exchanger organically combines the interlayer cabin and the tube array, has reasonable structure, can resist a heat exchanging medium with the temperature as high as 1200 DEG C and exchanges heat sufficiently.
Description
technical field [0001] The invention relates to a heat exchanger, especially a high-temperature heat exchanger, and belongs to the technical field of heat exchange facilities. Background technique [0002] Clamp and tube heat exchangers are commonly used heat exchange facilities in many industries. The Chinese patent application with the application number CN02222477.7 discloses a gas water heater, which mainly consists of a burner, a heat exchanger, a hot water folder, a controller, an air inlet and outlet, and a housing. Its characteristics are: the shape is a cylinder, and the upper and lower ends of the machine support the shell to buckle and fix it and connect it into a closed whole. The inner surface contains a cylindrical hot water folder with a hot water outlet at the lower part, and the upper end and the exhaust gas are exhaled. The tubes are connected, and the lower end is connected with the fresh air inlet tube. A burner and a heat exchanger are installed in the ...
