Abstract
The utility model relates to a washing dechlorination integrated device applied to waste incineration fly ash cement preparation, which comprises a machine frame. A bin with two open ends is installed on the machine frame, a roller driven to rotate by a motor is installed in the bin, the roller wall of the roller is full of micro-holes to form a filter screen, a roller cover is arranged at one end of the roller, a feed port is mounted on the roller cover, a material pushing disk is arranged at the other end of the roller, the rear side of the material pushing disk is connected with an oil cylinder pushing arm, a spraying pipe is arranged in the bin arranged above the roller, and a drainage pipe opening is arranged at the bottom of the bin. The washing dechlorination integrated device applied to the waste incineration fly ash cement preparation is simple in structure, achieves multi-washing and dehydration in one device, enables a complete set of system to be simplified greatly, washes the filter screen of the roller while washing ash, saves backwash water, and reduces overall water application rate by more than 60%. The roller rotates to drive materials to be turn over, and the materials do not need to be stirred by high speed water flow, thereby achieving low speed washing, greatly reducing energy consumption, and simultaneously reducing device abrasion.
Description
Technical field
The utility model relates to solid particulate and cleans and dewatering unit, especially prepares the washing dechlorination integrated apparatus in the cement to a kind of incineration of refuse flyash that is applied to.
Background technology
Flying dust is meant the fine particle that gets in the collection of garbage incinerating power plant flue gas purification system, contains organic pollutant and trace heavy metals such as benzopyrene, benzanthrene, Dioxins in the flying dust, therefore is classified as danger wastes.The disposal of flying dust generally is a Hazardous wastes landfill yard landfill or with flying dust resource utilization making cement building materials.Dual mode is compared, and the flying dust making cement is a better choice, and have following advantage: 1, processing cost is relatively low, and 2, realized the complete resource utilization of flying dust, 3, without land occupation; 4, pyrolytic decomposition Dioxins etc. is with thorough elimination secondary pollution.
But the flying dust making cement must reduce cl content in the flying dust, and too high cl content can have a strong impact on cement kiln and cement quality, so must carry out pre-treatment to flying dust---and the washing dechlorination makes cl content be lower than 0.5% through washing, to reach into the kiln standard.The specific equipment that does not also have at present this respect.
Summary of the invention
The purpose of the utility model is to prepare the washing dechlorination integrated apparatus technical scheme in the cement to a kind of incineration of refuse flyash that is applied to that the problems referred to above propose, and prepares the pretreatment process of cement to flying dust---make the flying dust cl content be lower than 0.5% through repeated water washing.
To achieve these goals, technical scheme of the present invention is: a kind of incineration of refuse flyash that is applied to prepares the washing dechlorination integrated apparatus in the cement, comprises frame; The bucket case of a both ends open is installed on the frame, the cylinder of a driven by motor rotation is installed in the bucket case, the barrel of cylinder is covered with micropore and forms filter screen; End at cylinder is provided with drum cover; Opening for feed is installed on drum cover, and the other end of cylinder is provided with the pusher dish, and the pusher dish is connected with the oil cylinder push arm at the back; Be provided with shower in the bucket case above the cylinder, be provided with the draining mouth of pipe in the bottom of bucket case.
Said opening for feed is the helical feed opening for feed of a sealing.
The beneficial effect of the utility model is:
1) detersive efficiency is high: the utility model is through the rotation of rotary drum, and material contacts with the inner core hole sizer, forms friction, effect of impact, makes flying dust and water thorough mixing simultaneously, efficient flush away impurity.
2) system simplification, simple in structure: the utility model has been realized repeatedly washing and has been dewatered and realize that in an equipment whole system is greatly simplified, and equipment inner structure is simple.
3) water application rate is low: the mode that dynamically sprays reduces the washing water yield greatly, simultaneously through with the cooperating of cylinder, washing barrel filter screen when washing ash saves backwash water, makes whole water application rate reduce more than 60%.
4) energy consumption reduces greatly: the utility model rolls through cylinder rotating band animal material, does not need high velocity jet to stir material, has realized the low speed washing, significantly reduces energy consumption, reduces equipment attrition simultaneously.
5) automatically monitoring and control automatically: charging, wash ash, dehydration, ash discharge fully automatic operation, and judge terminal point, need not manual work, use easy to operate through on-line monitoring.
Below in conjunction with accompanying drawing embodiment the present invention is made a detailed description.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of incineration of refuse flyash that is applied to prepares the washing dechlorination integrated apparatus embodiment in the cement, and referring to Fig. 1, said device comprises frame 1; The bucket case 2 of a both ends open is installed on the frame, the cylinder 3 of a driven by motor rotation is installed in the bucket case, the barrel of cylinder is covered with micropore and forms filter screen; End at cylinder is provided with drum cover 4; Opening for feed 5 is installed on drum cover, and the other end of cylinder is provided with pusher dish 6, and push pedal is connected with oil cylinder push arm 7 at the back; Be provided with shower 8 in the bucket case above the cylinder, be provided with the draining mouth of pipe 9 in the bottom of bucket case.Be provided with discharge groove 10 for the ease of discharging at the opening part of cylinder, the below of discharge groove is a feed belt 11.
Poplar ash when preventing charging, said opening for feed is the helical feed opening for feed of a sealing.
The operation of present embodiment equipment divides four-stage
Fs: charging---material gets into cylinder by opening for feed; Electric motor starting drives the cylinder low speed rotation of suit; Material is evenly distributed on the cylinder inner segment screen wall, and simultaneously sprinkling system is started working, and when inventory reaches cylinder inner core volume 1/4 ~ 1/3, stops charging.
Subordinate phase: wash material---cylinder middling speed rotation, sprinkling system works on, and reaches cylinder urceolus bucket case volume 1/4 ~ 1/3 o'clock until the water yield, and sprinkling system quits work
Phase III: dehydration---bucket case water discharge valve is opened, and cylinder rotates at full speed simultaneously, and under centrifugal action, the liquid phase thing passes the cylinder wall filter opening and discharges, and outside liquid discharge pipe discharge machine, solid formation is trapped in and forms annular cake layer in the cylinder.Repeatedly wash repeatable operation subordinate phase, phase III like need, judge terminal point with on-line monitoring equipment.
Stage: discharge---material-pulling device starts, and drum cover is opened.Under material-pulling device promotes, cylinder end motion in the pusher rim, thereby the cylinder cake layer outwards moves cylinder in the discharge in the promotion of pusher dish, outside blow tank discharge machine.
