Abstract
The invention discloses a kind of methods handling oil containing waste using station boiler, include the following steps：Pending greasy filth dangerous waste object is sent into storage in greasy filth holding vessel；Greasy filth is fallen into out of greasy filth holding vessel in drum filter；During drum filter rotation drives greasy filth rolling therein, liquid and little particle group lease making sieve pore fall into the filtered greasy filth tank in bottom in greasy filth, and bulky grain component falls into the impurity tank of drum filter bottom end in greasy filth；The fuel gas generated in greasy filth heating process is taken away to be sent into Boiler Furnace and is burnt；Greasy filth in filtered greasy filth tank through pipeline to furnace fuel oil nozzle, and sprays into burning in boiler；Large granular impurity enters stove burning with feeding coal-grinding mechanism powder after raw coal premix in impurity tank.The present invention by sludge filtration and respectively processing fed to boiler burning, can both dispose greasy filth dangerous waste object, not generate other wastes such as bioxin, and using the heat of greasy filth, realize that process is easy, initial cost is few.
Description
Technical field
The invention belongs to greasy filth hazardous waste disposal technical fields, and in particular to a kind of to handle greasy filth using station boiler
The method of danger wastes.
Background technology
Greasy filth is a kind of substance generated in oil exploitation and process, mainly by crude oil, moisture, clay sand, life
The compositions such as object organic matter.The substance containing benzene homologues, phenols, anthracene, pyrene etc. in greasy filth with foul smell and toxicity, seriously threatens week
The existence of collarette border and the mankind and health.Greasy filth has been put into《National Hazard waste catalogue》, unprocessed to discharge.
Currently, common greasy filth dangerous waste processing mode has：Curing process method, partition method, bioanalysis, stacking method, pyrolysis are burnt
Burning method etc., these methods have the shortcomings that investment is big, treatment effeciency is low, processing cost is high.
Invention content
The object of the present invention is to provide a kind of methods handling oil containing waste using station boiler, and this method is by greasy filth mistake
Simultaneously processing fed to boiler burning respectively is filtered, greasy filth dangerous waste object can have both been disposed, and not generate other wastes such as bioxin, and available
The heat of greasy filth realizes that process is easy, and initial cost is few.
The present invention adopts the following technical scheme that realize：
A method of greasy filth danger wastes being handled using station boiler, are included the following steps：
1) pending greasy filth dangerous waste object is sent into greasy filth holding vessel through manual or automatic charging gear and is stored；
2) greasy filth is fallen into through charging gear in drum filter out of greasy filth holding vessel；
3) during drum filter rotation drives greasy filth rolling therein, liquid and little particle group lease making sieve in greasy filth
Hole falls into the filtered greasy filth tank in bottom, and bulky grain component falls into the impurity tank of drum filter bottom end in greasy filth；
4) there is pipeline above impurity tank, and there is wind turbine to take the fuel gas generated in greasy filth heating process away feeding boiler
Burning in stove avoids exploding in drum filter；
5) greasy filth in filtered greasy filth tank through pipeline to furnace fuel oil nozzle, and sprays into burning in boiler；
6) level-sensing device is set in impurity tank, periodically releases the large granular impurity in impurity tank, and sent after being premixed with raw coal
Enter coal-grinding mechanism powder and enters stove burning.
The present invention, which further improves, to be, is further included introducing steam heater in greasy filth holding vessel in step 1), is used
In the temperature for improving greasy filth, make greasy filth that there is good mobility.
The present invention, which further improves, to be, further includes the introducing steam heater in drum filter in step 2)
Heat greasy filth so that greasy filth keeps good mobility.
The present invention, which further improves, to be, steam or high-temperature flue gas is taken to heat greasy filth.
The present invention, which further improves, to be, the drum filter in step 3), according to point of solid particulate matter in greasy filth
Cloth situation takes one or more levels series connection.
The present invention, which further improves, to be, the fuel nozzle in step 5), using the original big oil gun system of boiler, or
New fuel nozzle is added on boiler.
The present invention, which further improves, to be, further includes the sealing shell for pack roller filter.
The present invention has following beneficial technique effect：
1, all the components in greasy filth can be entered to stove burning processing；
2, greasy filth not will produce the harmful substances such as bioxin through station boiler high-temperature process；
3, greasy filth is handled in this manner, smaller to the change of station boiler, equipment investment is small, and using in greasy filth
Heat power generation；
4, the processing cost that greasy filth dangerous waste object is handled by station boiler is low, and treatment effeciency is high, has good Environmental Effect
Benefit and social benefit.

Fig. 1 is the greasy filth dangerous waste object conversion process figure of the present invention.
Fig. 2 is the greasy filth dangerous waste object trans-utilization schematic diagram of the present invention.
In figure：1- greasy filth holding vessels, 2- drum filters, 3- greasy filth tanks, 4- impurity tanks, 5- steam heaters, 6- sealings
Shell, 7- pipelines.
Specific implementation mode
The present invention is made further instructions below in conjunction with drawings and examples.
As depicted in figs. 1 and 2, a kind of method handling greasy filth danger wastes using station boiler provided by the invention,
Include the following steps：
1) pending greasy filth dangerous waste object is sent into storage in greasy filth holding vessel 1 through manual or automatic charging gear, wherein oil
Steam heater 5 is introduced in mud holding vessel 1, improves the temperature of greasy filth, makes greasy filth that there is good mobility；
2) greasy filth is fallen into through charging gear in drum filter 2 out of greasy filth holding vessel 1, wherein drum filter 2 is arranged
Steam heater 5 is introduced in sealing shell 6, in drum filter 2 to heat greasy filth, and greasy filth is made to keep good mobility；
3) during the rotation of drum filter 2 drives greasy filth rolling therein, liquid and little particle group lease making in greasy filth
Sieve pore falls into the filtered greasy filth tank 3 in bottom, and bulky grain component falls into the impurity tank 4 of 2 bottom end of drum filter in greasy filth；
4) there is pipeline 7 in 4 top of impurity tank, and has wind turbine to take the fuel gas generated in greasy filth heating process away feeding pot
Burning in stove stove avoids exploding in drum filter 2；
