Description
Technical field
The utility model relates to flying ash washing process field, relates in particular to a kind of solid waste burning flying dust water washing device.
Background technology
For the solid waste burning flying dust, wherein contain very high salinity (mainly being chlorine, sulphur, alkali composition), make the processing disposal and the recycling of flying dust run into various difficulties, therefore necessaryly must wash preliminary treatment, reduce the content of harmful components such as chlorine, sulphur, alkali flying dust.
Mentioning in the patent 03825874.9 sprays water flying ash when mobile on filter press simultaneously washes desalination, wash desalination immediately, have advantages such as equipment is simple, easy and simple to handle, occupation of land is little, but there are relevant issues such as washing institute water requirement is big, dechlorination effect is not good in this patented technology.
Adopt secondary water washing technology in the patent 200820130430.5, equipment adopts a stirring pool+primary sedimentation basin+secondary stirring pool+secondary sedimentation tank to be provided with, there are a plurality of problems in this equipment: 1, the conveying of device interior flying dust adopts pipeline and pump to beat, because fly ash granule is tiny, although pipeline is provided with the muddy water release valve, still easily result in blockage, in addition fly ash granule the and wherein salt and the alkali of high-load also will speed up losing of slush pump; 2, patent adopts natural gravity to be deposited in the mud-water separation effect and is much worse than press filtration, dewatering such as centrifugal greatly, thereby will cause the decline of washing dechlorination effect or the rising of water consumption; 3, will stir with the precipitation two procedures and be located away from two separate units, increase the complicated property of operation and the configuration of pipeline.
Summary of the invention
Because flying ash is a kind of hazardous waste that health and ecological environment are had very big harmfulness, therefore must be noted that the secondary pollution problem of being strictly on guard against that flying dust scatters and causes in whole water-washing process and equipment design configurations.The utility model has designed a kind of water-saving and dechlorination effect is good, simple in equipment, easy and simple to handle, stable flying dust water washing device.
A kind of solid waste burning flying dust water washing device, comprise the first washing stirring pool, first dehydration equipment, the second washing stirring pool, second dehydration equipment, the 3rd washing stirring pool, the 3rd dehydration equipment, first reuse pool and second reuse pool, wherein first wash stirring pool, first dehydration equipment, the second washing stirring pool, second dehydration equipment, the 3rd washing stirring pool, the 3rd dehydration equipment connects successively, the second washing stirring pool and dehydration equipment are equipped with pipeline and are communicated with first reuse pool, and the 3rd washing stirring pool and the 3rd dehydration equipment are equipped with pipeline and are communicated with second reuse pool.
When complete set of equipments of the present invention moves, flying ash at first enters the first washing stirring pool, use from the recycle-water mixing fresh supplemented water of first reuse pool and once wash, flying dust fully mixes with rinse water, makes soluble component strippings such as chlorine, alkali, stops to stir after washing is finished, make the flying dust natural sedimentation, obtain one-level supernatant and one-level mortar, the one-level supernatant is sent to Waste Water Treatment, and the one-level mortar goes first dehydration equipment to carry out primary dewatering.Primary dewatering obtains one-level filtrate and one-level ash cake after handling, and one-level filtrate is sent to Waste Water Treatment, and the one-level ash cake is delivered to the second washing stirring pool by belt conveyor and carried out secondary water washing.
The rinse water that the second washing stirring pool uses is from the recycle-water of second reuse pool and the mixing water of fresh supplemented water.The one-level ash cake is washed stirring pool after secondary water washing second, flying dust natural sedimentation in the second washing stirring pool, obtain secondary supernatant and secondary mortar, secondary supernatant enters first reuse pool, and the secondary mortar goes second dehydration equipment to carry out the second dehydration operation.Obtain secondary filtrate and secondary ash cake behind the second dehydration, secondary filtrate venting first reuse pool, secondary ash cake are delivered to the 3rd washing stirring pool by belt conveyor and are carried out three washings.After secondary supernatant and secondary filtrate are mixed, can be back to once washing in first reuse pool.
The secondary ash cake obtains three grades of supernatants and ash in class III slurry after three washings in the 3rd washing stirring pool, three grades of supernatants are sent to second reuse pool, the ash in class III slurry goes the 3rd dehydration equipment to carry out the 3rd dehydrating operations, obtain three grades of filtrates and ash in class III cake, three grades of filtrates enter second reuse pool, and the ash in class III cake is finished dechlorination can carry out follow-up disposal with dehydration.After mixing, three grades of supernatants and three grades of filtrates can be back to secondary water washing in second reuse pool.
Advantage of the present utility model:
1, by stirring flying dust is fully contacted with water, guarantee the stripping of chlorine, sulphur, alkaloid substance in the flying dust, the filter-press dehydration effect is good simultaneously, guarantees disposed of in its entirety effect and using water wisely;
2, stir and be deposited in the same pond and finish, simplified equipment and operation;
3, automaticity height, action required employee is few;
4, at utmost reduce the setting of pipe-line system and pump, significantly reduce the probability of obstruction and device damage, make running more stable.
