Description
Technical field
The present invention relates to the technical field of Treatment of Sludge, more particularly to a kind of anhydration system for processing sludge.
Background technology
In in recent years, the continuous improvement of the mud handling capacity of China with sewage enterprise to sewage treatment capacity, its product
The growth rate of amount is also constantly increasing.End in by the end of September, 2015, according to investigations statistics：National city-level, it is at county level (including
Cities and towns) city built up sewage treatment plant 3830 altogether, and sewage treatment capacity is up to 1.62 billion cubic meters/day, annual life
Produce the sludge of several ten million tons of water content 80%.Show that all types of sludge produced by China have 80% according to investigation and analysis report
Below be all that, not through effective process, wherein most is all arbitrarily to huddle to leave about, neither one rational stacking planning and
Process, to environment extremely serious impact is brought.
The processing mode of sludge increasingly receives the attention of country and people, up to the present, China to sludge
Processing mode is mainly following four：Agricultural, landfill is burned, building materials；For sludge is in the application of agricultural aspect, due to dirt
The moisture content of mud is too high, and volume is larger, and mud dry weight is less, and this results in sludge and there is very big difficulty in transportation,
Freight volume is big, and cost of transportation is higher, and dehydrated sludge cake is relatively difficult in shattering process, just needs when being operated in the fields
Some complementary machinery equipments are wanted to carry out coordinate operation, the technology has in actual applications very big difficulty；For landfill
This Treatment of Sludge methods, according to national Specification：The moisture content of sludge have to be lower than 50% and just can carry out at landfill
Reason；If dewatered sludge is directly burned, need to add a large amount of auxiliary fuels, this results in processing cost and be significantly increased；When
Sludge as building materials use when, enterprise will face huge cost of transportation and processing cost, and economic benefit is relatively low.So no matter taking
Any processing mode to sludge, first has to carry out drying and other treatment to sludge.
Sludge drying mainly has heat drying, mechanical mummification and solar energy desiccation etc., and the mode of wherein heat drying has steam, heat
Wind and flue gas, the efficiency high of mummification.And mechanical mummification generally can not be reduced to less than 50% moisture, solar energy desiccation efficiency
It is low, affected greatly by weather.The application for a patent for invention of publication No. CN103723902A discloses " a kind of sludge drying method and dress
Put ", the desiccation apparatus are by dry kiln and dryer group into and drying machine is located in dry kiln, is furnished with drying machine untreated
Sludge, thermal source flue gas is entered in kiln from the bottom of dry kiln, is looped around outside drying machine, and the shell of drying machine is heated, tail gas from
Flow out on kiln top；After sludge in drying machine is heated to, the waste gas of the inside is then flowed into gas-liquid separation device, so as to realize sludge
Mummification.
But the desiccation apparatus also have the disadvantages that：
1st, untreated sludge is deposited directly in drying machine, and cloth is uneven, and heating surface area is few, and mummification speed is slow；
