Abstract
The invention relates to a dewatered garbage processing and shaped carbon manufacturing method for paper mill. The steps of the method are as follows: indirectly heating the dewatered garbage of a paper mill with a relatively low temperature of <=270DEG C by heating reaction equipment of a thermal conduction carrier of a thermal conduction boiler; enabling the water in the dehydrated garbage to evaporate; manufacturing shaped carbon(carbon rods or carbon balls) after anhydration, coking and charing; and returning the manufactured shape carbon for combustion to heat the boiler. The heat produced from the combustion is used for production and the slag is used to make slag bricks for building, which achieve an objective of garbage disposal. Dioxins pollution is not produced during the process. Tail gas and stinking gas are discharged after reaching a tail gas standard. The disposal operation fee for disposing water-containing paper-making garbage (water content <=80%) is about 50 Yuan per ton (not including depreciation for plant assets).
Description
Technical field the present invention relates to a kind of paper mill dehydration garbage disposal system type charcoal method
Background technology waste paper or plant papermaking are generally all adopted and are soaked the making beating papermaking process.Paper pulp utilization rate about 90%, wherein 10% paper fiber remains in the water, and water is through flocculation, deposition qualified discharge, and the garbage dewatering that precipitates is handled.Dehydration msw water content about 80%, alkalescence, thickness, brownish black, dense smelly, be difficult for drying, output is big.It is reported that area output papermaking every day rubbish in Fuyang, Zhejiang Province can not be handled for more than 3000 ton, has had a strong impact on local industrial development, and has limited the quantity of to examine and maybe will not ratify to build enterprise of the same type again.
Inventor's urban wastewater treatment firm Treatment of Sludge that began one's study as far back as 2002; " city sludge low-temperature carbonization cycle of treatment is utilized technology " project is tried nearly two years out in the changzhou; Ripe back promotes the center scientific and technological result assessment on March 5th, 2010 through house and the development in science and technology of town and country construction portion, and expert opinion is:
(1) technological document that provides is complete, meets the assessment requirement.(2) this technology is under low temperature environment, sludge carbonization to be transformed into carbon rod, has effectively kept sludge calorific value, and carbon rod is acted as a fuel is used for sludge carbonization again, reaches the purpose that Treatment of Sludge is disposed.This technical feasibility is one of technology that can supply the selection of city sludge treatment and disposal.(3) this technology and other Treatment of Sludge compared with techniques having distinguishing feature aspect low-temperature carbonization, thermal source recycle, the complete sets of equipmentization, will produce good benefits in environment and social benefit after the popularization.Evaluation Commission thinks that this technology reaches leading domestic level in similar technical field, agrees after this to have born 100 tons of/day Treatment of Sludge first stage of the project in the high and new technology industrial development zone, Suzhou through assessment, and the June in this year goes into operation and checks and accepts.Solved a series of difficult problems in the process, and improved and declared seven national patents, application number is 200910009648.4; 200910119720.9; 201010166394.X; 200910250080.5; 201010166421.3; 201010000238.6; 201010238820.6.Through the paper mill is investigated, the rubbish constituent is analyzed, sum up and studied a kind of paper mill dehydration garbage disposal charcoal processing method, declare national patent simultaneously.
Water becomes water vapour, mummification, coking, charing, system type charcoal (carbon rod or charcoal ball) in the summary of the invention employing heat conduction boiler heat conduction indirect low temperature of carrier reacting by heating equipment (≤270 ℃) the reacting by heating paper mill dehydration rubbish; Return boiler combustion in the production again; Heat is used for producing; Slag system ash bricks is used for building, reaches the garbage disposal purpose.Not producing bioxin in the process pollutes.Tail gas, foul smell are handled the back qualified discharge in the process.Moisture papermaking rubbish (moisture content≤80%) is handled about 50 yuan/ton of operating charges (not containing depreciation of fixed assets).
Description of drawings Fig. 1 is a process chart of the present invention
The practical implementation method
1. make heat conduction boiler, heat conduction carrier reacting by heating equipment, system type charcoal equipment, washing tail gas, foul smell digestion facility, rubbish and charcoal conveying equipment are installed, slag is done complete set of equipments such as brick.
2. collect rubbish storage, metering and loading materials and the supporting automated production disposal of refuse of garbage disposal complete set of equipments disjunctor.
3. gasification, coking, charing system type charcoal one machine production rubbish.
4. washing tail gas, foul smell digestion process are handled water networking discharging, the supporting completion of gas qualified discharge.
5. slag brickmaking is used for building, harmless treatment paper mill dehydration rubbish.
