The device can effectively lower the flue gas temperature in the flue and reduce the granular powder dust in the flue gas.
Description
Technical field
The utility model relates to environmental protection equipment, specifically a kind of device that is used for the cooling down high-temperature flue gas and reduces dust in flue gas.
Background technology
At metallurgy industry, electric stove dust is a problem that is difficult to thoroughly solve always.Electric stove dust needs a whole set of process equipment, and the fume trap cover that wherein is arranged at the body of heater top is an important components, is used to collect the flue gas that rises when opening bell.Fume trap cover utilizes pipeline to be connected with pulse dust collector, and waste gas is discharged through aiutage after the pulse deduster is handled.On the bell of electric furnace, also should utilize a flue with refrigerating function---be commonly called as the 4th hole and be connected with pulse dust collector with water-cooled solid matter pipe flue, so that the operating temperature of regulating impulse deduster, and the high-temp waste gas that produces when electric furnace worked is in time got rid of, guarantee the operate as normal of electric furnace, simultaneously, turn round for guaranteeing that pulse dust collector is under a kind of good state all the time, on this flue, should connect dust treatment and cooling systems such as some combustion settling chambers, smog cooling chamber.
In the prior art, used smog cooling technology mainly contains two kinds: the water-cooled solid matter pipe flue about 1, utilizing approximately to be as long as fifty meters---a kind of sleeve pipe that is provided with outside smoke discharging pipe, the flue of water-filling cooling between sleeve pipe and smoke discharging pipe again.When flue gas flowed in this long flue, its heat water that is cooled was taken away, and has reduced the temperature of flue gas.2, without water-cooled solid matter pipe flue, directly flue is blown, utilize swiftly flowing air-flow to reduce flue-gas temperature with cold wind.The common issue with that this dual mode exists is that energy consumption is too high, causes operating cost too high.
Summary of the invention
The purpose of this utility model is to design a kind of energy-efficient smog cooling tower, and this smog cooling tower can effectively reduce the temperature of flue gas, and some the graininess dust in the flue gas are disposed, to alleviate the live load of pulse dust collector.
Its main technical schemes is in the bottom of tower body gas approach to be set, and on the top of tower body exhanst gas outlet is set, and between the import and export passage in tower body fog-spray nozzle is set.
Gas approach is positioned at the side of tower body, and utilizes pipeline to be connected with the outlet flue of body of heater; At this moment can flue-dust retainer be set in the bottom of tower body.
Gas approach also can be positioned at the bottom of tower body, and directly is connected with the outlet flue of body of heater.
A road of fog-spray nozzle utilizes pipeline to be connected with the compressed air bag, and another road utilizes pipeline to be connected with the supply mains, and automatic aqueous vapor valve is installed respectively on pipeline separately, and the aqueous vapor valve utilizes lead to be connected with controller respectively automatically.
Side at body of heater is provided with fire door, and opposite side is provided with an import of high temperature.
The arrangement mode of the spout in the fog-spray nozzle can be circular arrangement; Or be rectangular arranged.
The utility model has the advantages that this device is installed on after, when flue gas enters cooling tower in flue, the water that is mist sprays in fog-spray nozzle, after flue gas fully contacts, can effectively lower flue-gas temperature, and the graininess dust suction back in the flue gas is sunk, make flue gas with lower temperature and contain the graininess dust less situation under enter in the pulse dust collector, thereby improved the operating mode of pulse dust collector, improve the efficiency of dust collection of pulse dust collector, especially after having cancelled the water-cooled solid matter pipe flue about being as long as fifty meters originally, greatly reduce equipment cost and operating cost, save a large amount of power and waters, can produce fine economic benefit and social benefit.

The specific embodiment
As shown in the figure: the bottom at tower body 1 is provided with gas approach, top at tower body 1 is provided with exhanst gas outlet, between the import and export passage in tower body 1 fog-spray nozzle 3 is set, a road of fog-spray nozzle 3 utilizes pipeline to be connected with compressed air bag 10, another road utilizes pipeline 2 to be connected with supply mains 11, and automatic aqueous vapor valve is installed respectively on pipeline separately, the aqueous vapor valve utilizes lead to be connected with controller 12 respectively automatically.Wherein compressed air bag 10 is used to provide gases at high pressure, and supply mains 11 is used to send water, and gas and water addition is separately realized by the automatic aqueous vapor valve of controller 12 controls.
Gas approach can be positioned at the side of tower body 1, and utilizes crooked pipeline 4 to be connected with the outlet flue 8 of body of heater 13, at this moment flue-dust retainer 5 can be set in the bottom of tower body 1, so that the lime-ash that produces is collected in together, regularly removes.
Gas approach also can be arranged at the bottom of tower body 1, and directly is connected with the outlet flue 8 of body of heater 13.Side at body of heater 13 is provided with fire door 6, and opposite side is provided with an import 7 of high-temperature flue gas.The arrangement mode of the spout in the fog-spray nozzle 3 can roundedly be arranged, as shown in Figure 4; Also can rectangularly arrange, see Fig. 3, specifically can decide according to the shape of tower body 1.
