Smelting furnace flue gas treatment device with raw material preheating function

Abstract

The invention discloses a smelting furnace flue gas treatment device with a raw material preheating function. The smelting furnace flue gas treatment device with the raw material preheating function comprises a smelting furnace, a water tank and a purification tank; the purification tank and the water tank are both located on the right side of the smelting furnace; the purification tank is located over the water tank; a first feeding hopper is fixedly communicated with the top of the smelting furnace; a smoke exhausting pipe is fixedly communicated with the right side face of the smelting furnace; a smoke inlet pipe is fixedly connected with the lower surface of the purification tank; a smoke outlet pipe is fixedly connected with the upper surface of the purification tank; and a water inlet pipe and a water outlet pipe are fixedly communicated with the top and the bottom of the water tank correspondingly. According to the smelting furnace flue gas treatment device with the raw material preheating function, the smoke exhausting pipe is fixedly communicated with the water tank, the space between two screen rings is filled with activated carbon, and the flue gas can be filtered and purified fully; and by arranging a feeding pipe in the purification tank, the two ends of the feeding pipe penetrate the left side wall and the right side wall of the purification tank correspondingly, and the problem that an existing flue gas treatment device cannot well utilize waste heat is solved.

Description

technical field [0001] The invention relates to the technical field of chemical smelting, in particular to a smelting furnace flue gas treatment device with a raw material preheating function. Background technique [0002] Smelting is a refining technology, which refers to the extraction of metals from ores by means of roasting, smelting, electrolysis and the use of chemicals; reducing impurities contained in metals or increasing certain components in metals to produce the required metals . [0003] The smelting furnace will produce a large amount of flue gas during the smelting process. The flue gas has a pungent smell and contains a lot of smoke and dust. Therefore, it is necessary to install a device for purifying the flue gas at the smoke outlet of the smelting furnace. The temperature of the flue gas is very high and contains a lot of heat, but most of the existing flue gas treatment devices cannot make good use of the waste heat.
