Description
Technical field
The invention belongs to Environmental pollution and control technical field, particularly relate to a kind of blade dryer mummification containing greasy dirt
The method of mud.
Background technology
The oily sludge that sewage treatment plant of oil refining enterprise produces is mainly derived from oil interceptor bed mud, floation tank scum silica frost and crude oil
Tank bottoms mud, is commonly called as " three mud ", owing to wherein containing the poisonous and harmful substances such as sulfide, benzene homologues, phenols, anthracene, pyrene, therefore, contains
Greasy dirt is classified as dangerous solid waste (HW08) by country, includes danger wastes in and is managed.
Along with socioeconomic growing, China is increasingly strict to environmental requirement, petrochemical industry specific resistance to filtration skill
The research and development of art are more and more important.At present, the process of oily sludge has been carried out widely studied by research worker both domestic and external, main
Processing method has solvent extraction, burning disposal method, solidification method, biological treatment etc., and such as Shaanxi Oil chemical research sets
The scientific research personnel of meter institute uses three-phase physical extraction method to process oily sludge and obtains good effect, after stirring mixes 20 minutes
Extraction yield can reach 97.3%.Naggar et al. uses toluene as the petroleum hydrocarbon in extractant extraction and recovery oily sludge
Class, it is thus achieved that the response rate of 75.9%.Burning method is a kind of method of volume that can reduce mud to greatest extent, current state
Interior most refinery uses burning method to process oily sludge, and the technology that Shengli Oil Field utilizes oily sludge to generate electricity has reached good
Environmental requirement, the application in oil field achieves notable achievement.Solidification method is wide variety of hazardous waste harmless treatment skill
Art, but be typically considered to be not suitable for for processing debirs, because some organic compound can suppress cement class firming agent
Hydration, and Organic substance generally the most not with firming agent generation chemical bond and effect, cause solidification effect the best.Athanasios
Et al. research find, organic states of cure different in oily sludge are not quite similar by different types of cement, only one
The mud dividing solidification reaches the standard of security landfill.Biological treatment is that Organic substance is decomposed by the metabolism utilizing microorganism,
Thus repair the place polluted by mineral oil or make oily waste innoxious, the research worker of domestic University of Petroleum China will contain
Carry out high-temperature aerobic fermentation after greasy dirt inoculation bacterium solution, the removing oil rate of mud 53% can be realized, but the method is the most also in reality
Test room conceptual phase.The main methods of oily sludge is respectively arranged with pluses and minuses, but for the reality having a large population and a few land with China, is subtracting
Little sludge volume aspect, burning method has certain advantage.
For the oily sludge that water content is high, the most additionally add fuel to carry out burning disposal, need it is carried out
Drying and other treatment, to improve calorific value, reduces volume simultaneously.At present, the drying technique of oily sludge includes ultrasonic method for pretreating, mud
Quenched method, hydrothermal treatment consists method, contact heat drying method and mediate contact heat drying method, relative to above several method, connect indirectly
Touch the advantages such as heat drying method has that the thermal efficiency is high, exhaust emissions amount is low and apparatus and process is simple, and paddle-dryer is as one
Planting efficient mediate contact drying equipment, because having compact conformation, floor space is little, heat utilization ratio is high and has self-purification capacity etc.
Feature, and it is applicable to the drying and other treatment of oily sludge.
The present invention combines existing equipment and processes the feature of mud, utilizes paddle-dryer that oily sludge is carried out mummification
Processing, establish applicable sludge drying control condition, the actual application for technique provides reference.
Summary of the invention
The feasibility of oily sludge is processed, with the oily sludge of sewage from oil refinery treatment plant in order to explore paddle-dryer
Carry out drying and other treatment experimental study for processing object, analyze different mummification temperature, drying time and mud quantity delivered to discharging
Moisture percentage in sewage sludge and the impact of calorific value, the present invention provides a kind of method of blade dryer mummification oily sludge.
In order to realize foregoing invention purpose, the present invention by the following technical solutions:
A kind of method of blade desiccant mummification oily sludge, comprises the following steps:
(1) first oily sludge delivers into paddle-dryer by screw pump；
(2) again saturated vapor is passed through in blade and the bore wall interlayer of blade dryer hollow, between oily sludge is carried out
The heating connect；
(3), after oily sludge is heated, moisture and the evaporation of part volatile organic matter form gas, and gas enters washing
Tower；
(4) gas is by after scrubbing tower, and the sewage of the mainly oil-containing of condensation, by oil-water separation, recovered oil divides, moisture
Enter Sewage Disposal；And incoagulable gas, then carry out burn processing；
(5) dried oily sludge being discharged blade dryer, the oily sludge as mummification packs storage.
As preferably, the quantity delivered of the oily sludge described in step (1) is 30-100kg/h.
As preferably, the temperature of the saturated vapor described in step (2) is 150-200 DEG C.
As preferably, in step (2), the heat time heating time of blade dryer is 20-60min.
Compared with prior art, there is advantages that
(1) after the oily sludge sample of moisture content 77.6% is processed by the method for the present invention, the dewatered sludge obtained
Moisture content can be down to 30%, calorific value reaches 4250kcal/kg, will process after oily sludge can use as fuel, become
Waste be changed into values.
(2) method of the present invention combines existing equipment and processes the feature of mud, utilizes paddle-dryer to containing greasy dirt
Mud carries out drying and other treatment, research different operating condition on moisture percentage in sewage sludge, sludge calorific value and the impact of generation waste water COD content,
To oily sludge drying process being applied the reference providing certain.
Accompanying drawing explanation
Fig. 1 is the process chart of the blade dryer mummification oily sludge of the present invention.
