Abstract
The invention discloses a rubber desulfurization system device which comprises a desulfurization cylinder depositing rubber powder. A sulfur dioxide gas outlet of the desulfurization cylinder is connected onto a gas inlet of a basin reaction cylinder through a bleeder pipe, water and quick lime are placed in the basin reaction cylinder, inlet sulfur dioxide is reacted with calcium hydroxide generated by water and the quick lime to generate calcium sulfate for sediment, pressed gas is discharged from a gas outlet of the basin reaction cylinder to enter a secondary reaction tank which is separated into more than two reaction tanks through separation plates, the water and the quick lime are placed in the reaction tanks, circulation holes are formed in the separation plates simultaneously, residual sulfur dioxide is repeatedly reacted in different reaction tanks and then is removed, sulphurous acid generated through desulfurization is discharged from the secondary reaction tank to enter the desulfurization cylinder to achieve circulated desulfurization. The rubber desulfurization system device is simple in structure, uses precipitability of the calcium sulfate after reaction, effectively removes sulphur elements, is low in energy and environment-friendly, is convenient to clear and saves investment.
Description
?
Technical field
The present invention relates to a kind of desulfurizer, be specifically related to a kind of being used for the sulphur of rubber is transformed into calcium sulfate precipitation, to reach the devulcanization of rubber system and device of desulfurization purpose.
Background technology
Along with the development of rubber industry, the output and the usage quantity of rubber are increasing rapidly always.Waste rubber materials such as junked tire are carried out regenerated using, become one of important utilization point of rubber industrialization engineering.As everyone knows, waste rubber regenerated key point is " desulfurization ", at present typical technology be with waste Crumb rubber with after oil plant mixes, through about 200 ℃ vapor pressure, stirring heating formation, the common chemical peptizer that also need add one type of organic disulfide.Its weak point is: processing unit is comparatively complicated, pollutes greatlyyer, and it is higher to consume energy simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, it is low to consume energy, the devulcanization of rubber system and device of economic environmental protection.
A kind of devulcanization of rubber system and device comprises the desulfurization cylinder of depositing rubber powder, and the sulfurous gas air outlet of said desulfurization cylinder is connected on the inlet mouth of basin reaction cylinder through eduction pipe; Said basin reaction cylinder is built-in with water and unslaked lime; Behind sulfurous gas that gets into and the calcium hydroxide reaction by water and unslaked lime generation, generate calcium sulfate precipitation, the gas after the processing is discharged entering secondary reaction pond, back from the air outlet of basin reaction cylinder; Said secondary reaction is divided into plural reaction tank through dividing plate in the pond; Said reaction tank is built-in with water and unslaked lime, offers opening on the said dividing plate simultaneously, and remaining sulfurous gas repeatedly reacts the back and removes in different reaction tanks; The sulfurous acid that is produced after the desulfurization is discharged from the secondary reaction pond and is entered into the desulfurization cylinder, realizes circulation desulfurization.
Said basin reaction cylinder bottom face can be offered the clean-up port that is used to remove calcium sulfate.
Be provided with sound damper in the said basin reaction cylinder.
The present invention is simple in structure, easy to make, has utilized reacted calcium sulfate precipitation property, has effectively removed element sulphur, not only low energy environmental protection, and be convenient to cleaning, saved investment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment 1
Referring to Fig. 1; A kind of devulcanization of rubber system and device provided by the invention; Comprise the desulfurization cylinder 1 of depositing rubber powder, the sulfurous gas air outlet 2 of said desulfurization cylinder 1 is connected through eduction pipe 3 on the inlet mouth of basin reaction cylinder 4, and said basin reaction cylinder 4 is built-in with water and unslaked lime (being quicklime); Sulfurous gas that gets into and calcium hydroxide (generating) by water and quicklime; The reaction back generates sedimentary calcium sulfate, can offer the clean-up port 5 that is used to remove calcium sulfate at basin reaction cylinder 4 bottom faces, installs sourdine 6 additional in reaction place of sulfurous gas and water and unslaked lime; Noise when not only having eliminated reaction can be accelerated the speed of response of sulfurous gas and water and unslaked lime to discharge orifice on the sourdine 6 simultaneously.Gas is after treatment discharged from the air outlet 7 at basin reaction cylinder 4 tops.
Because the gas after basin reaction cylinder 4 is handled still has the possibility that sulfurous gas; So its air outlet 7 is connected on the secondary reaction pond 8; Be divided into plural reaction tank 10 through dividing plate 9 in the secondary reaction pond 8; Said reaction tank 10 is built-in with water and unslaked lime, offers opening 11 simultaneously on the said dividing plate 9, and remaining sulfurous gas can repeatedly react the back and remove in different reaction tank 10; The sulfurous acid that is produced after the desulfurization is discharged from secondary reaction pond 8 and is entered into desulfurization cylinder 1, realizes circulation desulfurization.
Claims (3)
1. a devulcanization of rubber system and device comprises the desulfurization cylinder of depositing rubber powder, it is characterized in that: the sulfurous gas air outlet of said desulfurization cylinder is connected on the inlet mouth of basin reaction cylinder through eduction pipe; Said basin reaction cylinder is built-in with water and unslaked lime; Behind sulfurous gas that gets into and the calcium hydroxide reaction by water and unslaked lime generation, generate calcium sulfate precipitation, the gas after the processing is discharged entering secondary reaction pond, back from the air outlet of basin reaction cylinder; Said secondary reaction is divided into plural reaction tank through dividing plate in the pond; Said reaction tank is built-in with water and unslaked lime, offers opening on the said dividing plate simultaneously, and remaining sulfurous gas repeatedly reacts the back and removes in different reaction tanks; The sulfurous acid that is produced after the desulfurization is discharged from the secondary reaction pond and is entered into the desulfurization cylinder, realizes circulation desulfurization.
