Description

Split type water-cooling heat exchanger of secondary combustion chamber of anode furnace Technical Field The utility model belongs to the technical field of anode furnaces, and particularly relates to a split water-cooling heat exchanger of a secondary combustion chamber of an anode furnace. Background In the process of smelting blister copper in an anode furnace, incompletely combusted gas in the furnace body enters a secondary combustion chamber for secondary combustion. Because the flue gas temperature of the secondary combustion chamber outlet is higher, direct discharge can lead to dust remover failure and follow-up flue gas treatment system failure. Therefore, a water-cooling heat exchanger is arranged at the outlet of the flue to cool the secondary combustion flue gas, so that the temperature of the flue gas is reduced to meet the operation condition requirement of the dust remover in the next procedure. Because the flue gas corrodes the heat exchanger tube bundle in the heat exchange process with the heat exchanger, the heat exchanger tube bundle leaks water. The installation space of the water-cooling heat exchanger is small, and the water-cooling heat exchanger needs to be installed firstly when equipment is installed, and then the flue is built for sealing. In the normal production process, if the situation that the heat exchanger tube bundle leaks occurs, the heat exchanger tube bundle cannot be cut off in time, the furnace is shut down, the cooling and water interruption are needed, the leaked branch pipelines are disconnected and welded to be dead, and if the leaked pipelines are more, the cooling and water reduction requirements cannot be met, the water-cooled heat exchanger needs to be replaced integrally, and the replacement is complicated, so that the production is severely restricted. Disclosure of utility model The utility model aims to provide a split type water-cooling heat exchanger of a secondary combustion chamber of an anode furnace, which can be disassembled, assembled and replaced in a split mode, is simple to replace and improves production efficiency. In order to achieve the purpose, the technical scheme adopted by the utility model is that the split type water-cooling heat exchanger of the secondary combustion chamber of the anode furnace comprises at least two heat exchanger bodies; The heat exchanger body comprises a water inlet main pipe, a water return main pipe and a supporting frame, wherein the water inlet main pipe is transversely arranged above the supporting frame, a plurality of water inlet branch pipes are communicated with the water inlet main pipe, each water inlet branch pipe penetrates through the supporting frame downwards and is connected with a heat exchange pipe, the heat exchange pipes are arranged in a serpentine mode, the water return main pipe is transversely arranged on one side of the water inlet main pipe, the water return main pipe is communicated with a plurality of water return branch pipes corresponding to the water inlet branch pipes, the water return branch pipes penetrate through the supporting frame downwards and are respectively communicated with one ends, far away from the water inlet branch pipes, of the plurality of heat exchange pipes, each water inlet branch pipe and each water return branch pipe are provided with stop valves, at least two heat exchanger bodies are sequentially arranged, and two water inlet main pipes and two water return main pipes of adjacent heat exchanger bodies are respectively connected.
