Description
Technical Field
The utility model belongs to the tail gas treatment field specifically is a collection device for granular ammonium sulfate tail gas dust.
Background
In my company granular ammonium sulfate [ chemical formula: (NH)4)2SO4 in the industrial production process, the product particles are dried mainly by hot flue gas generated by burning raw coal in a fluidized bed furnace SO as to dry the moisture of the product particles and ensure the quality of the product.
It is known that coal-fired flue gas carries a large amount of coal ash dust particles, and if the part of the coal ash dust particles is not purified and collected, the flue gas carrying the large amount of coal ash dust particles is directly used for drying the ammonium sulfate product. The ammonium sulfate product has more impurities and substandard nutrients, thereby causing product quality accidents. Therefore, flue gas at the outlet of the fluidized bed furnace needs to be purified, and hot air with less content of coal ash and dust particles is used for drying the ammonium sulfate product so as to ensure that the content of impurities in the ammonium sulfate product particles is less and the nutrients reach the standard.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to the shortcoming of above-mentioned fluidized bed furnace flue gas, provides a collection device for granular ammonium sulfate tail gas dust.
A collecting device for granular ammonium sulfate tail gas dust comprises a cylindrical barrel and a dust conveying port of a conical dust collecting device at the lower part of the barrel; the barrel and the dust conveying opening of the dust collecting device are of an integrated structure; a dust collecting device inlet pipeline is arranged on one side above the cylinder body, and a dust collecting device outlet pipeline is arranged above the cylinder body; 6 dust collecting device dust collecting clapboards are distributed in the barrel, and a rapping device is arranged on the dust collecting clapboard of the dust collecting device.
And the inlet pipeline of the dust collecting device is connected with the outlet pipeline of the fluidized bed furnace.
And a heat-insulating layer is arranged outside the barrel of the dust collecting device.
The utility model discloses a theory of operation: hot flue gas generated by the coal burning of the fluidized bed furnace enters the dust collecting device through the output pipeline. After hot flue gas tangentially enters the dust collection device, under the action of centrifugal force generated when the dust collection partition plate and the flue gas rotate, flue gas dust is separated from hot flue gas flow and is accumulated on the dust collection partition plate and the cylinder. Collecting the flue gas to an ash conveying port for discharge under the action of a rapping device and the gravity of dust, discharging the purified hot flue gas from the top of the dust collecting device, and then, drying granular ammonium sulfate product particles in a production system.
The utility model has the advantages that:
(1) the device can effectively purify the flue gas, coal ash and dust generated by the fluidized bed furnace, and effectively prevent impurities from entering a product drying system so as to ensure that the product quality is qualified.
(2) The device of the utility model can ensure that the furnace ash and the impurities after the combustion of the fluidized bed furnace can be effectively collected.
(3) The utility model discloses the device is arranged at fluidized bed furnace air-out pipe position, does not occupy the mounted position in addition, and the device design is simple, excellent in use effect.
(4) The utility model discloses the device fault rate is low, does not basically need the maintenance.
(5) The utility model discloses the device is quiet equipment, need not use the electric energy or cause other energy consumptions.
