Abstract
A floating agent for coal is composed of waste rubber oil (10 to 11), spreading agent (1 to 1.5) and foaming agent (1 to 1.5) according to the weight portions. The coal dressing effect is the same as the effect of traditional floating agent for coal composed of coal (diesel) oil, and secondary octyl alcoho. The present invention has the advantages of wide range of material source, energy saving and reduced coal dressing cost; the present invention simultaneously opens up a novel way for the utilization of a junked tire.
Description
Technical field
The present invention relates to a kind of Floating agent for coal, specifically belong to a kind of Floating agent for coal of mainly forming by scrap rubber oil.
Background technology
Development of modern industry is to the continuous growth of coal demand and the improve of mechanical coal mining technology, and the duff amount of coal mining process also increases day by day.China's selected ability of coal during "the 10th five-years" reaches 5.5 hundred million tons, produces nearly 100,000,000 tons of coal slime.Reclaim the cleaned coal that can select (25%-85%) by handling, hundred million yuan of recovery value 150-170 have great economic implications.Yet kerosene commonly used of coal separation at present or light diesel fuel are collecting agent, will consume tens thousand of tons every year, in energy-intensive today, develops new collecting agent, reduce the coal separation cost, are very necessary to the flotation development of coal.
On the other hand, about 3,000 ten thousand of the annual junked tire that produces of China, and along with developing of automobile industry increases progressively with 15%.Junked tire is the Harmful Waste of generally acknowledging in the world, and is at present international and domestic very limited to recovery and Utilization of Wastetires, and mainly by four approach: (1) renovation utilizes; (2) the damaged tire chopping is used for generating as fuel; (3) Pintsch process reclaims rubber hydrocarbon, carbon black, fuel oil; (4) glue powder.Owing to contain a large amount of sulphur in the crude rubber oil, the fuel oil that is used for vehicle needs desulfuration purification, complex process, cost height.So present domestic most of junked tire is directly as furnace fuel oil after the thick refining.
At present, the flotation of domestic coal, the flotation agent that mainly uses kerosene, diesel oil and secondary octanol to form.Waste energy on the one hand, on the other hand coal separation cost height.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can reduce the coal separation cost, again the Floating agent for coal of energy savings.
A kind of Floating agent for coal provided by the invention is characterised in that by weight by scrap rubber oil 10-11, spreading agent 1-1.5, foaming agent 1-1.5 composition; Described spreading agent is a polyethylene glycol; Described foaming agent is a fatty acid ester.
Described scrap rubber oil is the crude rubber oil by the waste and used rubber tyre refining.
The consumption of Floating agent for coal of the present invention is generally 1.0-1.5Kg/ ton coal.
Compared with prior art, the present invention directly utilizes the rough rubber oil of junked tire pyrolysis gained high sulfur content to be used as the coal collecting agent, replaces kerosene or diesel oil, energy savings greatly; Opened up a new way for the processing of junked tire simultaneously; Also reduced the coal separation cost.
The specific embodiment
Example 1: with Xishan coal ore deposit, Taiyuan lean coal is coal sample (ash content 16.5%), carries out coal separation, coal concentration 100g/L, Floating agent for coal consumption 1.5Kg per ton in the self-control flotation device.Flotation coal result such as following table:
| Sequence number | Agent for capturing A | Foaming agent B | Spreading agent C | A∶B∶C | Clean coal yield % | Cleans ash % | Tail coal productive rate % | Tail coal ash content % |
| 1 | Kerosene | Secondary octanol | - | 10∶1 | 83.6 | 11.69 | 16.4 | 41.02 |
| 2 | Scrap rubber oil | Fatty acid ester | Polyethylene glycol | 10∶1∶1.5 | 87.63 | 12 | 12.37 | 48.5 |
Annotate: sequence number 1 prior art (reference); Sequence number 2 the present invention
Example 2: with colliery, Jiexiu, Shanxi coal is coal sample (ash content 13%), adopts the XFDM1-1.5 flotation device, coal concentration 80g/L, Floating agent for coal consumption 1Kg per ton.Flotation coal result such as following table:
| Sequence number | Agent for capturing A | Foaming agent B | Spreading agent C | A∶B∶C | Clean coal yield % | Cleans ash % | Tail coal productive rate % | Tail coal ash content % |
| 1 * | Kerosene | Secondary octanol | - | 10∶1 | 89.74 | 10.02 | 10.26 | 39.25 |
| 2 | Scrap rubber oil | Fatty acid ester | Polyethylene glycol | 10∶1∶1.5 | 82.18 | 7.97 | 17.82 | 36.2 |
Annotate: sequence number 1 prior art (reference); Sequence number 2 the present invention
Claims (3)
1. a Floating agent for coal is characterised in that by weight by scrap rubber oil 10-11, spreading agent 1-1.5, foaming agent 1-1.5 composition; Described spreading agent is a polyethylene glycol; Described foaming agent is a fatty acid ester.
2. according to the described a kind of Floating agent for coal of claim 1, be characterised in that described scrap rubber oil is the crude rubber oil by the waste and used rubber tyre refining.
