[0002] In the process of smelting zinc oxide, because the proportion of ore is the majority, and the temperature of the ore can only meet the process requirements at 1100°C, at this time the zinc has been dissolved and gasified, and will pass through the 800mm distance with the flue gas and dust. N-type pipes are naturally cooled and then discharged to the chimney. The waste heat after cooling through N-type pipes cannot be recovered. The main reason is that the cooled zinc and dust will accumulate on the heat exchange pipes, so until now the flue gas The waste heat is not recovered

Embodiment Construction
[0026] The present invention will be further described below in conjunction with specific drawings.
[0027] Such as figure 1 As shown, a high-temperature dust removal and heat exchange integrated equipment includes a gas chamber shell 2, and a flue gas inlet 1 is arranged on one side of the gas chamber shell 2 obliquely, and the inner wall of the gas chamber shell 2 on the same side as the flue gas inlet 1 The upper part is horizontally connected with the impact type flat dust collector 3, and the inner end of the impact type flat dust collector 3 extends to the middle part of the air chamber shell 2, and the impact type flat dust collector 3 is located below the flue gas inlet 1; The upper ring of the inner wall is provided with an impact dust collecting plate 4; both the impact flat dust collector 3 and the impact dust collecting plate 4 can be made of high temperature resistant cast iron. The impact type dust collector 3 rebounds to the impact type dust collecting plate 4...

The invention relates to high-temperature dust removal and heat exchange integrated equipment. The equipment comprises an air chamber shell, wherein a flue gas inlet is obliquely formed in the side portion of one side of the air chamber shell; an impact type flat plate dust collector is transversely connected to the inner wall of the air chamber shell on the same side as the flue gas inlet; the inner end of the impact type flat plate dust collector extends to the middle of the air chamber shell; the impact type flat plate dust collector is located below the flue gas inlet; an impact type dustcollecting plate is annularly arranged on the inner wall of the air chamber shell; the bottom of the air chamber shell is communicated with the upper end of a dust collection heat exchanger; and the lower end of a straight cylinder shell is communicated with a blind dust collection pipe. The equipment has the advantages of high heat exchange efficiency, energy conservation, good dust removal effect, simple manufacturing process, low production cost and convenience in installation, maintenance and cleaning.
Description
technical field [0001] The invention relates to a high-temperature dust removal and heat exchange integrated equipment, which belongs to the technical field of dust removal and heat exchange equipment. Background technique [0002] In the process of smelting zinc oxide, because the proportion of ore is the majority, and the temperature of the ore can only meet the process requirements at 1100°C, at this time the zinc has been dissolved and gasified, and will pass through the 800mm distance with the flue gas and dust. N-type pipes are naturally cooled and then discharged to the chimney. The waste heat after cooling through N-type pipes cannot be recovered. The main reason is that the cooled zinc and dust will accumulate on the heat exchange pipes, so until now the flue gas The waste heat is not recovered. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a high-temperature dust removal and ...
