Abstract
The invention discloses the method and devices that a kind of gutter oil microwave-heating gas is used for coal slime flotation.The specific method is as follows: being placed in the gutter oil in trench oil drum in three in microwave reactor mouthfuls of quartz flasks by the suction of pan feeding pipeline using peristaltic pump; it is pyrolyzed under certain microwave heating power; the pyrolysis gas that pyrolysis generates is passed directly into the flotation cell on flotation device, while the protective gas of conditions of certain gas flow being continually fed into three mouthfuls of quartz flasks by protective gas pipeline.By the above-mentioned means, the present invention can reduce coal slime flotation cost and improve flotation efficiency, have preferable social benefit, environmental benefit and economic benefit while gutter oil is effectively treated.
Description
Technical field
The present invention relates to the method and devices that a kind of gutter oil microwave-heating gas is used for coal slime flotation, belong to the utilization of resources
Technical field.
Background technique
With the development of economy, catering trade market persistently keeps good situation.It can be generated in catering trade actual operation
A large amount of waste grease, that is, gutter oil.If gutter oil is without effective processing, it will bring some undesirable influences.One side
Face, if being discharged into the Nature without processing, with certain pollution and the wasting of resources；On the other hand, if flowing again
Enter catering market, it will bring potential threat to people's health.Therefore, it is carried out reasonably handling to reach sharp again
With being a kind of urgent demand.And the non-polar hydrocarbon oil collecting agent used in the coal slime floating process in coal industry field
There is close place with such oil, it, can be while solving the problems, such as gutter oil if the two can link together, and it can be significantly
Reduce industrial cost.
Summary of the invention
The object of the present invention is to provide the method and devices that a kind of gutter oil microwave-heating gas is used for coal slime flotation；The party
Method and device can convert gutter oil to the substance that can replace collecting agent used in coal slime floating process.The method both may be used
To solve the environmental problem and social concern of gutter oil, the cost of coal slime flotation process also can be effectively reduced.
The technical solution adopted in the present invention is as follows:
The gutter oil in trench oil drum is pumped into three mouthfuls be placed in microwave reactor by pan feeding pipeline using peristaltic pump
It in quartz flask, is pyrolyzed under certain microwave heating power, the pyrolysis gas for being pyrolyzed generation is direct by pyrolysis gas duct
It is passed through in the flotation cell on flotation device, the protective gas in gas cylinder is with certain gas flow by being equipped with gas flowmeter
Protective gas pipeline is continually fed into three mouthfuls of quartz flasks.
A kind of above-mentioned gutter oil microwave-heating gas is used for the method and device of coal slime flotation, the microwave reactor
Working frequency be 915MHz.
A kind of above-mentioned gutter oil microwave-heating gas is used for the method and device of coal slime flotation, the microwave heating function
Rate is 2000W-5000W.
A kind of above-mentioned gutter oil microwave-heating gas is used for the method and device of coal slime flotation, and the protective gas is
Refer to nitrogen or argon gas.
A kind of above-mentioned gutter oil microwave-heating gas is used for the method and device of coal slime flotation, and the gas flow is
30-100ml/min。
Beneficial effects of the present invention are shown: converting institute in coal slime floating process for gutter oil using microwave-heating technology
Using the substitute of collecting agent, on the one hand efficiently solve society and the environmental problem of gutter oil, on the other hand with traditional coal slime
Flotation is compared with collecting agent, this substitute is passed through in gaseous form, is highly dispersed in flotation cell, has better flotation effect
Fruit, while its price is more cheap.
