Abstract
The invention provides a device for preliminarily reducing smoke dust in big furnace tail gas through a cyclone dust collector. The device comprises a big furnace pit, the cyclone dust collector is arranged behind the big furnace pit, and an outlet of the cyclone dust collector communicates with a waste heat boiler. A coal gas burner is mounted in a heating chamber of the waste heat boiler. A gas outlet of the waste heat boiler communicates with a static dust collector. The device has the beneficial effects that a combustion chamber is transformed, the cyclone dust collector is arranged behind a big furnace, smoke enters the waste heat boiler after passing through the cyclone dust collector, and therefore the dust content of the smoke can be greatly reduced, the smoke dust discharge amount of a desulfurizing tower is reduced, and the environment is protected. Materials collected below the dust collector are directly conveyed into a leaching tank, and therefore previous secondary heating on the materials is avoided, and energy is saved; and in addition, the coal gas burner is mounted in the heating chamber of the waste heat boiler and is used for spraying out a small amount of coal gas, pulverized coal and combustible gas which are not combusted completely in the smoke can be ignited, and the boiler is fully heated. Energy waste is avoided.
Description
Technical field
The present invention relates to smoke dust-removing equipment technical field, particularly relate to and a kind of adopt cyclone dust extractor to early decline the device of flue dust in big furnace exhaust gas.
Background technology
Celestite and feed coal carry out reduction roasting under the high temperature conditions in thick strontium rotary kiln, SrSO4 in Ore is reduced into the rough SrS of solubility, it is called for short thick strontium, rotary kiln end is burner, and kiln tail is dust storage chamber, and have surplus heat in dust storage chamber boiler, flue gas enters electrostatic dust collection equipment through waste heat boiler, then through air-introduced machine, entering desulfurizing tower, the de-dirt of flue gas desulfurization and denitrification then drains into air.But, through sampling observation, the dirt that electrostatic precipitation is taken off is also containing a small amount of combustible (being similar to a small amount of coal dust), and has just gone out in the flue gas of big stove also containing a small amount of carbon monoxide etc., has that combustible is not sufficiently combusted just to be taken away by air-introduced machine.
Flue gas adds hot cell through waste heat boiler, some ash that falls adds bottom, hot cell because action of gravity is deposited on, ash is fallen through (this fully calcined material) for this part, we collect by scrapper conveyor, then add in big stove by elevator again and burn away, like this, this partial material, by secondary clacining, wastes the energy.
Summary of the invention
The invention provides and a kind of adopt cyclone dust extractor to early decline the device of flue dust in big furnace exhaust gas; combustor is transformed; at big furnace rear, cyclone dust extractor is set; allow flue gas first after cyclone dust extractor; enter back into waste heat boiler; the dustiness of flue gas can be substantially reduced, reduce the smoke discharge amount of desulfurizing tower, protect environment.The material collected under cleaner unit, directly transport is to leaching groove, this avoid the post bake in the past to material, saves the energy；It addition, add installation coal gas burner in hot cell at waste heat boiler, spray a small amount of coal gas with burner, it is possible to unburned coal dust completely and imflammable gas in some burning fume, fully heat to boiler.Avoid the waste of the energy.
For solving above-mentioned technical problem, the invention provides and a kind of adopt cyclone dust extractor to early decline the device of flue dust in big furnace exhaust gas, including big stove melt pit, it is equipped with cyclone dust extractor after described big stove melt pit, the outlet of described cyclone dust extractor has surplus heat boiler, the heating indoor location of described waste heat boiler has coal gas burner, the gas outlet connection electrostatic precipitator of waste heat boiler.
The one or more technical schemes provided in the embodiment of the present application, at least have the following technical effect that or advantage:
Combustor is transformed, cyclone dust extractor is set at big furnace rear, allow flue gas first after cyclone dust extractor, enter back into waste heat boiler, it is possible to be substantially reduced the dustiness of flue gas, reduce the smoke discharge amount of desulfurizing tower, protect environment.The material collected under cleaner unit, directly transport is to leaching groove, this avoid the post bake in the past to material, saves the energy；It addition, add installation coal gas burner in hot cell at waste heat boiler, spray a small amount of coal gas with burner, it is possible to unburned coal dust completely and imflammable gas in some burning fume, fully heat to boiler.Avoid the waste of the energy.

Fig. 1 is the overall structure schematic diagram of the embodiment of the present application.
In figure, 1, big stove melt pit, 2, cyclone dust extractor, 3, waste heat boiler, 4, add hot cell, 5, coal gas burner, 6, electrostatic precipitator.
Detailed description of the invention
In order to be better understood from technique scheme, below in conjunction with Figure of description and specific embodiment, technique scheme is described in detail.
As shown in Figure 1, a kind of described in the present embodiment adopts cyclone dust extractor to early decline the device of flue dust in big furnace exhaust gas, including big stove melt pit 1, it is equipped with cyclone dust extractor 2 after described big stove melt pit 1, the outlet of described cyclone dust extractor 2 has surplus heat boiler 3, adding of described waste heat boiler 3 is provided with coal gas burner 5 in hot cell 4, combustor is transformed by the gas outlet connection electrostatic precipitator 6 of waste heat boiler 3, at big furnace rear, cyclone dust extractor 2 is set, allow flue gas first after cyclone dust extractor 2, enter back into waste heat boiler 3, the dustiness of flue gas can be substantially reduced, reduce the smoke discharge amount of desulfurizing tower, protect environment.The material that cyclone dust extractor is collected for 2 times, directly transport is to leaching groove, this avoid the post bake in the past to material, saves the energy；It addition, hot cell 4 is installed coal gas burner 5 in adding of waste heat boiler 3, spray a small amount of coal gas with burner, it is possible to unburned coal dust completely and imflammable gas in some burning fume, fully heat to boiler.Avoid the waste of the energy.
