Cyclone separator and gas-liquid solid separation system
Technical field
The present invention relates to gas-liquid-solid separation technology fields, are detached in particular to a kind of cyclone separator and gas-liquid-solid
System.
Background technology
Currently, coal water slurry gasification is the important link of coal producing light olefins industry, Nitrogenous Fertilizer Industry and coal liquifaction industry etc..Water
The raw gas that coal slurry gasification generates is typically passed through chilling process primary wash, cooling and gas-liquid-solid separation.It is light after separation
Component raw gas is sent to follow-up workshop section.Since coal water slurry gasification usually carries out in gasification furnace combustion chamber, raw gas can carry winged
Ash, slag are directly entered shock chamber, this results in the indoor water quality of Quench poor, and the impurity such as a large amount of flying dusts are carried secretly with raw gas
Moisture enter in scrubbing tower through venturi, and then affect the water quality in scrubbing tower and scrubbing tower top exit purified gas
Cleannes.Meanwhile inevitably can also there are some impurity, the liquid phase part in the relatively clean liquid phase part of wash tower bottoms
It is sent to chilling ring of gasifying furnace after Quench water pump pressure-raising, filter filtering, the raw gas that gasification furnace combustion chamber is come is carried out preliminary
Washing, cooling.Therefore, in the water cycle process of gasification, since raw gas purifying is not thorough, it often will appear chilled water filtering
The phenomenon that device blocks, chilling ring fouling is serious, system resistance drop rapid increase, is unable to stability contorting, even so as to cause production
Destroy the balance of grey water treatment system.
In addition, raw gas made from coal water slurry gasification generally goes through shock chamber, syngas outlet spray, Venturi scrubbing
Fed downstream process after device, scrubbing tower water-bath and demister Pyatyi cleaning dust.Coal Gasification water consumption is larger, and gasify water system
It is usually maintained in higher internal circulating load.However, although raw gas have passed through multistage washing, purifying, coal gas band water band ash can not be kept away
Exempt from, this results in needing to be continuously replenished outside battery limit (BL) fresh water to maintain the balance of water system, therefore, improves system water quality to closing weight
It wants.
There is a kind of gas washing purification technique in the prior art.The main implementation steps of the technique are as follows:Washings follow
Ring pump send a part of Heisui River pressurization come from scrubbing tower Heisui River storage tank to Venturi scrubber, is mixed with from out-of-bounds raw gas
It closes, enters after the solid particles such as the lime-ash carried secretly in raw gas are moistened, bonded and increased by Heisui River in venturi and detach
Device carries out level-one washing.Raw gas down-comer in separator flows downward, and most of lime-ash enters in separator bottom liquid phase,
The Heisui River of generation is discharged into black water treatment system.Raw gas is ascended into along down-comer and gas-guide tube annular space in scrubbing tower water-bath.Slightly
Coal gas is flowed up by water-bath, with from washing water-circulating pump another part Heisui River and external technique moisturizing in scrubbing tower
It is inversely contacted on the tower tray of top.Coal gas after two level washing is sent into subsequent conversion by the baffle plate demister on tower tray top
Process, the Heisui River that scrubbing tower generates are discharged into black water treatment system.However, the technique, in implementation process, initial stage of coming into operation is because of water quality
Good, solid content is few, and Venturi scrubber has preferable spray atomizing and washing effect to raw gas.With the long-time of production
It runs, the solid content in wash tower bottoms Heisui River certainly will will increase, and pass it through pump pressurization and send to venturi and will result in blockage
Venturi spray apertures cause the pressure drop increase of gasification system and energy consumption to increase.In addition, the increase of wash tower bottoms Heisui River solid content is also
It can cause inversely to contact the decline of cleaning dust significant effect at the top of scrubbing tower with coal gas, be unfavorable for the purification of coal gas, longtime running
Raw gas is extremely difficult to expected clean-up effect.
In addition, there is also one kind in the prior art passes through main washing, water-bath, secondary washing, rotation in dust-laden raw gas occasion
The vertical separator of flow separation combination unit.The above-mentioned vertical separator course of work is:Raw gas enters from gas feed, passes through
Entrance inside extending tube in gas feed is mixed with the washings entered from main wash mill, by being washed in central tube
Enter gas cylinder after dedusting, comes into full contact with carry out water-bath washing after then eliminating big bubble by bulb-breaking device with washings.Water
Raw gas after bath carries out secondary washing, carries out gas-liquid separation by cyclone separator, the raw gas after dedusting is by gas vent
Rough coal gas separating device is excluded, dust-laden washings are exported by device bottom through collection cone balling-up and are discharged.But the technique is in reality
During applying, because setting washings are more, the higher flow velocity of coal gas, can cause raw gas to carry part dust particale and produce coal in addition
Gas outlet, and the pressure drop of separator can be caused to increase, energy consumption increases, and is unfavorable for maintaining the even running of production.
