Description
Technical field
The utility model belongs to the technical field of gas-liquid two-phase flow device foam removal, and separation one is segregated more particularly to one kind
Change the low pressure drop demister of equipment.
Background technology
It is common in vehicle repair major flow device that liquid foam entrainment is that crystallizing evaporator, distillation rectifying column, fractional condensation equipment etc. are present
Phenomenon.Liquid foam entrainment will cause crystallizing evaporator condensate quality to decline, and distillation efficiency of rectification tower declines, and segregates equipment weight group
The separative efficiency divided declines, and increases the difficulty and expense of subsequent treatment.Liquid foam entrainment causes product loss plate efficiency to decline, seriously
Shi Zaocheng equipment can not normal operation.
To prevent and reducing liquid foam entrainment, it is necessary to install demister in separation equipment is segregated, the type of demister has respectively
Kind various kinds, such as silk screen, grid.The shortcomings that these demisters is：Pressure drop increase, and need periodic cleaning etc..
Existing silk screen defoaming separator, system is easily caused when using in the system of fig. 1 and the problem of following occurs：
It was found that light component gas is mixed into heavy constituent, then in follow-up cooler partial condensation, later separation is influenceed, and in portion
Blocked in subset；It was found that the water in light component is appeared in heavy constituent, the separation in downstream is influenceed；Heat is uneven, influences weight
Component cools down and cold air heating.
The reason for causing above mentioned problem is：Due to carrying a small amount of particle in hot gas secretly, it is blocked in after running a period of time
In the gap of silk screen, pressure drop is added, when the pressure drop of hot-side channel is gone beyond the limit of, plus thermal stress caused by cold fluid and hot fluid
Collective effect, heat is surveyed air flue and deform, cause welding seam breaking, hot gas leaks；Hot gas is short by slit leakage
Road is directly entered light component gas passage, in follow-up cooler and pipeline, or even has been found that heavy constituent within the compressor, this can also
It may determine that in the temperature difference of heavy constituent and light component gas (should temperature there was only the difference of very little)；The leakage loss of heavy constituent gas,
The reduction of heavy constituent condensate liquid quantity is directly resulted in, further influences the flow into destilling tower, and exchanged heat with bottom of towe discharging
Amount, thus influence drop temperature；The leakage shorts of heavy constituent gas, the oil gas into condensation portion is reduced, causes local overcooling,
The steam partial condensation as light component is caused, thus influences the feed composition of destilling tower；Because heavy constituent gas enters segregator
Amount reduction, also influence and unstripped gas between heat exchange balance, and then influence synthesis gas feeding temperature.
