Powder reclaiming device, said powder reclaiming device are the tube that an end has second duckbilled, and the other end of this tube is arranged at the lower end of said cyclone separator, are used for a part of separating the powder that obtains through the drying oven cyclone separator is reclaimed.
Further, the bottom of said drying oven cyclone separator also is provided with first duckbilled, and said first duckbilled is used for a part of separating the material that obtains through the drying oven cyclone separator is delivered to drying oven according to demand through the leakage of drying oven charging aperture.
Further, the said first duckbilled discharging opening is over against the drying oven charging aperture.
Further; The port of export of said first duckbilled is equipped with the duckbilled adjusting device; This duckbilled adjusting device realizes the control of powder amount making dry mash amount as required return drying oven that remaining dry mash reclaims through second duckbilled voluntarily through the size of restriction duckbilled opening.
Further, said duckbilled adjusting device is a plate object.
Dust pelletizing system also comprises an assisted dust-collecting device as previously mentioned, and wherein said assisted dust-collecting device is arranged on the wet scrubber, and the gas that is used for wet scrubber is not taken off fully dirt further takes off dirt, and then tail gas is entered air.
Introduce below; A kind of based on said dry dedusting and the powder recovery method that has the dry dust pelletizing system of powder reclaiming device of this utility model; The wet stock belt conveyor transports wet stock and gets into drying oven through the drying oven charging aperture; Wet stock part behind kiln dried directly outputs to the dry material belt from the drying oven discharging opening and is recovered, and another part gets into the drying oven cyclone separator with the form of tail gas, gets into drying oven through a dry material part that obtains after separating through the circulation of first duckbilled; Another part is transported on the dry material belt through powder reclaiming device (tube that has second duckbilled), is recovered then.The tail gas of remnants in the drying oven cyclone separator gets into wet scrubber through air-introduced machine, directly enters atmosphere through the tail gas part after the dedusting water washing; A part gets into the assisted dust-collecting device, enters atmosphere after separating through the aqueous vapor of assisted dust-collecting device, owing to passed through the particularly dedusting effect of assisted dust-collecting device of deduster; Make and enter the tail gas in the atmosphere; Reach exhaust emission standard, so far, the dry dedusting of whole tail gas and the recovery of powder finish.
Adopted the equipment and the method for present technique scheme, obtained significant beneficial effect: at first, reduced the dust content that enters tail gas in the atmosphere, this has not only practiced thrift resource, has also alleviated the serious phenomenon of dry factory building airborne dust, has protected environment; Secondly, the dry material part that obtains through cyclone separator returns drying oven through first duckbilled, all the other powders are recovered on the dry material belt through powder reclaiming device voluntarily, have reduced the load of dust pelletizing system, have improved the service life of dust pelletizing system.
Description of drawings
Fig. 1 is the structure diagram of the said dry dust pelletizing system of the utility model, and the glide path sketch after the dusty gas entering dust pelletizing system.
The specific embodiment
In order better to understand the described dry dust pelletizing system of the utility model and based on the powder recovery method of this system, below in conjunction with accompanying drawing one of them specific embodiment to be done further detailed explanation, specific explanations is following:
As shown in Figure 1, be the structure diagram and the mobile sketch of tail gas in this device of the utility model one specific embodiment.Can be clearly seen that by figure this dry dust arrester that has powder recovery function includes drying system, dust pelletizing system and powder reclaiming device; Wherein, Said drying system includes again: drying oven 3; Be arranged at the air-heater 14 of drying oven 3 inner bottom parts, be arranged at drying oven charging aperture 2, drying oven discharging opening 10 and offgas duct 12 on the drying oven 3, said drying system is used for the wet stock oven dry that gets into drying system; Said dust pelletizing system includes again: drying oven cyclone separator 4 and wet scrubber 1; One end of said drying oven cyclone separator 4 is connected with drying oven 3 through offgas duct 12; The other end is communicated with wet scrubber 1 through air-introduced machine 11, and said dust pelletizing system is used for the tail gas that comes out from drying oven 3 and get into wherein through offgas duct is carried out dedusting; Powder reclaiming device; Said powder reclaiming device is the tube 15 that an end has second duckbilled 6; The other end of this tube 15 is arranged at the lower end of said cyclone separator 4, is used for reclaiming separating a part that obtains powder through drying oven cyclone separator 4.The described dry dust arrester of present embodiment also includes an assisted dust-collecting device 13 and a duckbilled adjusting device 7; Said assisted dust-collecting device 13 is arranged on the said wet scrubber 1; After getting into the tail gas process dedusting water washing of wet scrubber 1; A part enters atmosphere, and another part enters atmosphere after separating moisture through assisted dust-collecting device 13.Described duckbilled adjusting device 7; Be embodied as a plate object in the present embodiment; Push-and-pull through plate object realizes the control to first duckbilled, 5 discharging openings size; And then realize control to dry material flow and influx, and said this plate object is installed on the discharge port end head of first duckbilled 5, and remaining powder is through the balance recovery voluntarily of second duckbilled.
