Abstract
The invention discloses a kind of efficient gas mixture recovery and utilization technologies, the recovery method carries out in the steps below: (1) oil-soot mixture generated in electrical carbon carbonisation being introduced into condenser first and condensed and separated, fallen into after the heavy oil component condensation in oil-soot mixture and be used as industrial chemicals in collecting tank；(2) then the smoke mixture for removing most of heavy oil component is passed through after burner is mixed with natural gas together in furnace chamber inner combustion, the heat for acquisition of burning is introduced into other equipment and uses；(3) smoke mixture of generation of burning in above-mentioned steps is passed through under the liquid level of alkaline aqueous solution by pipeline and carries out purified treatment, and purified gas is discharged into atmosphere.Recovery method of the invention is turned waste into wealth, and by discarded oil smoke by recycling, is produced industrial chemicals and heat while reducing environmental pollution, is created value, saves the energy and protect environment.
Description
Technical field
The present invention relates to novel charcoal material preparation field, specifically a kind of efficient gas mixture recycles skill
Art.
Background technique
During the carbonization-activation of electrical carbon, a large amount of oil-soot mixture can be generated, the main component of oil-soot mixture is
Heavy oil, and contain a certain amount of carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide and a small amount of ash content, heavy oil can be used
In coating processed, waterproof material etc..If the oil-soot mixture generated during carbonization-activation of leaving is discharged into air, not only can be serious
Environment is polluted, and will cause the serious waste of resource.
Summary of the invention
In light of the defects in the prior art, the purpose of the invention is to provide a kind of efficient gas mixtures to recycle skill
Art.
The purpose of the present invention is what is solved by the following technical programs:
A kind of efficient gas mixture recovery and utilization technology, it is characterised in that the recovery method in the steps below into
Row:
(1) oil-soot mixture generated in electrical carbon carbonisation is introduced into condenser first and is condensed and separated, oil smoke
It is fallen into after heavy oil component condensation in mixture and is used as industrial chemicals in collecting tank；
(2) then the smoke mixture for removing most of heavy oil component is passed through after burner is mixed with natural gas and is existed together
Furnace chamber inner combustion, the heat for acquisition of burning are introduced into other equipment and use；
(3) burn in above-mentioned steps generation smoke mixture be passed through by pipeline under the liquid level of alkaline aqueous solution carry out it is net
Change processing, purified gas are discharged into atmosphere.
The weight of heavy oil component in the step (1) is not less than the 80% of oil-soot mixture total weight.
Smoke mixture in the step (2) mainly contain carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide with
And a small amount of ash content.
The weight ratio of smoke mixture and natural gas in the step (2) is 1: 1-10.
Calory burning in the step (2) is introduced into drying equipment to dry particle charcoal.
Alkaline aqueous solution in the step (3) is the mixed aqueous solution of potassium hydroxide and polyamines.
Sour gas in smoke mixture and alkaline aqueous solution in the step (3) carry out neutralization reaction.
Purified gas in the step (3) contains a small amount of carbon dioxide.
The present invention has the following advantages compared with prior art:
The present invention is condensed Main Components heavy oil therein by condensing and separating oil-soot mixture introducing condenser
It is used as industrial chemicals afterwards, burns after then mixing smoke mixture remaining after condensation separation with natural gas, and sufficiently
The heat obtained using burning, the remaining smoke mixture after full combustion, which is passed through in the alkaline pond of multiple cycle operations, to be carried out
Purification is neutralized, only remaining a small amount of carbon dioxide is discharged into atmosphere；Above-mentioned recovery method is turned waste into wealth, and discarded oil smoke is passed through back
It receives and utilizes, produce industrial chemicals and heat while reducing environmental pollution, create value, save the energy and protect
Environment.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
Embodiment 1
In electrical carbon carbonisation, a large amount of oil-soot mixtures can be generated when being in 400 DEG C -700 DEG C in carbide furnace, first
The oil-soot mixture is introduced into condenser and is condensed and separated, the heavy oil group that its weight is more than 80% is occupied in oil-soot mixture
It falls into after part condensation and is used as industrial chemicals in collecting tank, heavy oil can be used for coating processed, waterproof material；Then the most of weight of removal
The smoke mixture of oily component is passed through after burner is mixed with natural gas together in furnace chamber inner combustion, and the heat for acquisition of burning introduces
To dry particle charcoal in drying equipment, wherein smoke mixture mainly contains carbon monoxide, carbon dioxide, nitric oxide, dioxy
Change nitrogen and a small amount of ash content, and inputting the smoke mixture of burner and the weight ratio of natural gas is 1: 3；Burn the cigarette generated
Gas mixture is passed through under the liquid level of the mixed aqueous solution of potassium hydroxide and polyamines by pipeline and carries out purified treatment, smoke mixture
In sour gas and alkaline aqueous solution carry out neutralization reaction, a small amount of ash content in smoke mixture precipitates in alkaline aqueous solution
Get off, only the purified gas of remaining a small amount of carbon dioxide is discharged into atmosphere.Recovery method of the invention is turned waste into wealth, by what is discarded
Oil smoke produces industrial chemicals and heat while reducing environmental pollution, creates value, saves energy by recycling
Source simultaneously protects environment.
