Abstract
A device for Separation and Recovery dithiocarbonic anhydride and nitrogen, described device is made up of the first knockout drum (1), the first surge tank (2), the first compressor (3), the first condenser (4), the second knockout drum (5), the second compressor (6), the second condenser (7) and the 3rd solid-liquid separation tank (8).Described device is by from producing in tail gas the nitrogen and dithiocarbonic anhydride mixed gases that eject after gas-liquid separator, and dithiocarbonic anhydride and nitrogen mixed gas enter surge tank, then enter into two-stage compression system; Compressed cooled dithiocarbonic anhydride gas is liquefied as dithiocarbonic anhydride liquid, and nitrogen is made a gift to someone nitrogen storage tank, for part producing system.The utility model can carry out the mixed gas of CS2 with N2 to be separated rear recycling in 100% ground, reach and optimize the environment of plant and eliminate CS2 gas is discharged to the inflammable and explosive potential safety hazard existed in air, serve again energy-saving and cost-reducing, reduction production cost, the multiple effect of increasing economic efficiency simultaneously.
Description
technical field
The utility model relates to a kind of from dithiocarbonic anhydride CS
2and nitrogen N
2mixed gas in Separation and Recovery CS
2and N
2device, belong to insoluble sulfur production process equipment technical field.
background technology
Dithiocarbonic anhydride CS
2and nitrogen N
2be use all the time and easy consumption material in insoluble sulfur production process, how reduce the gas consumption problem mixed, become the difficult problem that annoying in domestic and international insoluble sulfur manufacturing enterprise technology always.Now Domestic is outer is adopt refrigerated water at condenser internal recycle CS to the recovery of this mixed gas
2single gas carries out being condensed into liquid state and reclaims, because of CS
2flash-point be negative 30 DEG C, and it is often and N in insoluble sulfur production process
2form mixed gas, and the boiling point of nitrogen is negative 195.8 DEG C, so adopt the CS2 that also just can be recovered to about 50% in this way, and has indivedual enterprise to use cryogenics, namely refrigerated water is adjusted to negative less than 30 DEG C, like this can CS
2amount be recovered to more than 90%, but it is large to there is energy consumption, Equipments Setting is high, aqueous vapor more mainly in this mixed gas is difficult to the separation removal reaching 100%, be plugged when using the medium channel in regular hour aftercondenser and just being accumulated gradually by the aqueous vapor of trace, cause and can not continue normally to work, simultaneously N
2do not recycle in these methods all always, but directly enter in air.
summary of the invention
The purpose of this utility model is, in order to solve a difficult problem for Separation and Recovery dithiocarbonic anhydride and nitrogen, the utility model proposes a kind of through stage compression dithiocarbonic anhydride (CS
2) and nitrogen (N
2) mixed gas carry out the device of Separation and Recovery dithiocarbonic anhydride and nitrogen, CS
2carry out being separated rear recycling with the mixed gas of N2.
Realizing the technical solution of the utility model is, the device of a kind of Separation and Recovery dithiocarbonic anhydride of the utility model and nitrogen comprises the first knockout drum and the first surge tank, also comprise the one stage of compression device be made up of the first compressor, the first condenser and the second knockout drum, form the second compression set by the second compressor, the second condenser and the 3rd knockout drum.
The mixed gas of dithiocarbonic anhydride and nitrogen enters the first knockout drum, and at the bottom of the deposit of moisture of carrying secretly in mixed gas to tank, the mixed gas part of dithiocarbonic anhydride and nitrogen is exported by the first separating tank and enters the first surge tank through pipeline; The pneumatic outlet of the first surge tank enters the first compressor through pipeline, and liquid portion goes out from tank lower valve door row; Mixed gas through the first compressor compresses enters the first condenser from the first compressor compresses outlet through pipeline; Mixed gas delivers to the second knockout drum by outlet through pipeline after the first condenser condenses; The gas that second knockout drum is separated enters the second compressor through pipeline, the CS of separation from outlet
2liquid goes out from tank lower valve door row; The gas entering the second compressor compresses send the second condenser after compression; Gas delivers to the 3rd knockout drum by outlet through pipeline after the second condenser condenses; The CS be separated
2liquid goes out from tank lower valve door row, and the gas of separation has been very pure N
2, send into nitrogen storage tank through pipeline.
The device working process of the utility model Separation and Recovery dithiocarbonic anhydride and nitrogen is as follows:
CS
2with nitrogen mixed gas through compressor one stage of compression, pressure is 0.03MPa ~ 0.1MPa, then through condenser condenses to about 25 DEG C, the dithiocarbonic anhydride gas major part of compression is condensed into liquid, enter gas-liquid separator tank again, liquid carbon disulphide is separated and is disposed to dithiocarbonic anhydride storage tank again.One stage of compression is carried the gas compression of coming, pressure is 0.1MPa ~ 0.35MPa, then through condenser condenses to about 25 DEG C, enters knockout drum, micro liquid dithiocarbonic anhydride is separated and is disposed to dithiocarbonic anhydride storage tank again, and above tank, expellant gas is the N that purity is higher
2enter nitrogen storage tank, reclaim N
2for part producing system.
The beneficial effects of the utility model are, the utility model adopts stage compression dithiocarbonic anhydride (CS
2) and nitrogen (N
2) mixed gas carry out Separation and Recovery CS
2and N
2device solve Separation and Recovery CS
2and N
2problem, can 100% ground CS
2and N
2mixed gas carry out being separated rear recycling, reach optimize the environment of plant eliminate a CS
2gas is discharged to the inflammable and explosive potential safety hazard existed in air, serves again energy-saving and cost-reducing, reduction production cost, the multiple effect of increasing economic efficiency simultaneously.
