Abstract
The utility model relates to a flue gas cleaning device, aiming to achieve a purpose that smoke and dust in the flue gas exhausted in a steel making process are separated and then are respectively recycled and reused. The flue gas cleaning device comprises a flue gas collector which is connected to a water tank through a cooling pipe, wherein the water tank is of a seal type structure, the tail end of the cooling pipe is arranged at the lower part of the water tank and is lower than the water level, a flue gas pipe is welded on the upper surface of the water tank in a sealing manner, the middle part of the flue gas pipe is provided with a gas drier and a fan, a dust removing tank is arranged in one side of the water tank, and a water outlet of the water tank is connected with the dust removing tank through a water pipe; and a filtering net is arranged in the dust removing tank, wherein a water outlet of the dust removing tank is provided with a water pump and is connected to a water inlet of the water tank through the water pipe. The whole flue gas cleaning device disclosed by the utility model has the advantages of simple structure, convenience in use, low cost and high practicability; the exhausted flue gas passes through the water tank so that the smoke and the dust are separated and can be respectively recycled and reused; and therefore, the purposes of energy saving and emission reduction as well as environment protection are well achieved.
Description
Technical field
The utility model relates to steelmaking equipment, specifically, is a kind of smoke eliminator.
Background technology
Steel mill can be discharged a large amount of flue gases in steel smelting procedure, comprising carbon monoxide, nitrogen, sulfur dioxide and a large amount of dust etc., if directly be discharged in the air, will cause very large pollution to environment.At present, China has formulated detailed requirement and standard to energy-saving and emission-reduction, and environmental protection is had higher requirement, and therefore, provides a kind of gas and the dust separation that will discharge in the flue gas, and the purifier of separately recycling is necessary in fact.
The utility model content
For the flue dust that reaches in the flue gas that will discharge in the steelmaking process separates, and the purpose of recycling, the utility model has been developed a kind of smoke eliminator, comprise the flue gas collector, described flue gas collector is connected to water tank by cooling pipe, described water tank is sealed construction, the tail end of described cooling pipe is positioned at the bottom of described water tank, and be lower than horizontal plane, the upper surface seal weld of described water tank is connected to flue, is connected with gas drying device and blower fan between the described flue, and a side of described water tank is provided with the dedusting pond, the delivery port of described water tank links to each other with described dedusting pond by water pipe, and described dedusting is provided with screen pack in the pond.
Wherein, the water outlet in described dedusting pond is provided with water pump, and is connected to the water inlet of described water tank by water pipe.
The beneficial effects of the utility model are: the flue gas of discharging separates flue dust by water tank, dust is soluble in water, gas after the separation can recycling by oven dry, dust by sedimentation and filtration as the mud recycling, accomplished well energy-saving and emission-reduction, and whole apparatus structure is simple, easy to use, with low cost, practicality is high.
