Abstract
The invention discloses a flue gas purification device in order to fulfill the aim that smoke and dust in flue gas discharged in a steelmaking process are separated and then are recycled. The flue gas purification device comprises a flue gas collector, wherein the flue gas collector is connected to a water tank through a cooling pipeline; the water tank adopts a sealed structure; the tail end of the cooling pipeline is positioned at the lower part of the water tank and is lower than a horizontal plane; a flue gas pipeline is welded to the upper surface of the water tank in a sealed manner; a gas drying device and a fan are arranged in the middle of the flue gas pipeline; a dust removal pool is arranged on one side of the water tank; a water outlet of the water tank is connected with a dust removal pool through a water pipe; a filter net is arranged in the dust removal pool; a water pump is arranged at the water outlet of the dust removal pool and is connected to a water inlet of the water tank through a water pipe. The whole flue gas purification device is simple in structure, convenient to use, low in cost and high in practicability; the smoke and the dust in the discharged flue gas are separated through the water tank and can be separately recycled; therefore, energy conservation and emission reduction are well realized, and the environment is protected.
Description
Technical field
The present invention relates to steelmaking equipment, specifically, is a kind of smoke eliminator.
Background technology
Steel mill, in steel smelting procedure, can be discharged a large amount of flue gases, comprising carbon monoxide, nitrogen, sulfur dioxide and a large amount of dust etc., if be directly discharged in 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, provide a kind of by gas and dust separation in discharge flue gas, and the purifier of recycling is separately necessary in fact.
Summary of the invention
In order to reach, the flue dust in the flue gas discharging in steelmaking process is separated, and the object of recycling, the present invention has developed a kind of smoke eliminator, comprise 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 lower than horizontal plane, the upper surface seal weld of described water tank is connected to flue, between described flue, be connected with gas drying device and blower fan, one side of described water tank is provided with dedusting pond, the delivery port of described water tank is connected with described dedusting pond by water pipe, described dedusting is provided with screen pack in 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 invention has the beneficial effects as follows: the flue gas of discharge separates flue dust by water tank, dust is soluble in water, gas after separation can recycling by drying, dust by sedimentation and filtration as mud recycling, accomplished well energy-saving and emission-reduction, and whole apparatus structure is simple, easy to use, with low cost, practicality is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1-flue gas collector, 2-cooling pipe, 3-water tank, 4-flue, 5-drying unit, 6-blower fan, 7-dedusting pond, 8-screen pack, 9-water pump.
The specific embodiment
As shown in Figure 1, a kind of smoke eliminator of the present invention, comprise flue gas collector 1, described flue gas collector 1 is connected to water tank 3 by cooling pipe 2, described water tank 3 is sealed construction, the tail end of described cooling pipe 2 is positioned at the bottom of described water tank 3, and lower than horizontal plane, the upper surface seal weld of described water tank 3 is connected to flue 4, between described flue 4, be connected with gas drying device 5 and blower fan 6, one side of described water tank 3 is provided with dedusting pond 7, the delivery port of described water tank 3 is connected with described dedusting pond 7 by water pipe, in described dedusting pond 7, be provided with screen pack 8, the water outlet in described dedusting pond 7 is provided with water pump 9, and be connected to the water inlet of described water tank 3 by water pipe.
The present invention is in the time of work, first the high-temperature gas that flue gas collector 1 is collected reduces temperature by cooling pipe 2, then reach water tank 3, dust in flue gas is soluble in water, gas is discharged by flue 4, after drying, deliver to next procedure recycling through blower fan 6, along with the separation of flue dust, dust density in water is increasing, after a period of time, by sewage discharge in dedusting pond 7, water tank 3 is put into a certain amount of clean water again by water inlet, dust is by precipitation and the filtration in dedusting pond 7, transported recycling as mud, water in dedusting pond 7 is by purifying, deliver to water tank recycling through water pump 9.
Claims (2)
1. a smoke eliminator, comprise flue gas collector, it is characterized in that, 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 lower than horizontal plane, the upper surface seal weld of described water tank is connected to flue, between described flue, be connected with gas drying device and blower fan, one side of described water tank is provided with dedusting pond, and the delivery port of described water tank is connected with described dedusting pond by water pipe, and described dedusting is provided with screen pack in pond.
