Description
Technical field
The utility model relates to a kind of vapor-liquid separating device, and particularly a kind of flash tank, belongs to chemical industry equipment field.
Background technology
In Chemical Manufacture, flash tank is a kind of chemical industry equipment of conventional vapor-liquid separation.Flash principle is that the liquid mixture that is dissolved with gas of high pressure enters in the flash tank of low pressure, and due to the unexpected reduction of pressure, the boiling point of liquid also decreases.Making fluid separation applications is the liquids and gases under reservoir pressure, and liquids in general forms product, and gas is separated from flash tank, thereby has realized liquefaction, cooling and the purification of vapor-liquid separation and mixture.Flash tank, for mixture vapor-liquid separation provides comparatively desirable space, can improve the effect of vapor-liquid separation simultaneously.Traditional flash tank is generally tank structure, high-temperature material enters flash tank by inlet along tank body tangential direction, rotates, under centrifugal action along tank inwall when material pressure declines, flash separation goes out the steam of liquid discharges from tank body top, and separated liquid is discharged from tank body lower part.There is the halfway problem of vapor-liquid separation in this flash tank.Both affect the gaseous mass reclaiming, and caused again certain product to run off.
The utility model will overcome the deficiencies in the prior art exactly, and a kind of novel flash tank is provided, the good separating effect of this flash tank, and gas, the purity liquid of recovery are high, can prevent the waste of raw material, are convenient to clean and sterilizing.
Utility model content
Problem to be solved in the utility model is: a kind of Novel flash tank is provided, this flash tank sprays material by feed pipe place shower nozzle to spray chamber below, liquid in mixed material drops to tank base at Action of Gravity Field, the steam flashing off is after flash chamber separation, after the separation of wire mesh demister, enter again separator and carry out further vapor-liquid separation, material vapor-liquid separation is obtained more thorough, prevent material waste, in addition, because material has been realized more thoroughly separated, the foam producing in waste gas is reduced, foam removal better effects if.
In order to address the above problem, the utility model is realized by following technology:
A flash tank, comprises tank body, feed pipe, demister, separator, escape pipe, discharge nozzle.Tank body is made by stainless steel material; Feed pipe is positioned at the below of tank body and stretches into tank inner chamber, and feed pipe is provided with valve and shower nozzle, is densely covered with spray orifice on shower nozzle, and shower nozzle is divided into spray separation chamber and flash chamber by tank inner chamber; Demister is positioned at the top of feed pipe, wire packing, consists of; Separator is positioned at tank body top, and separator can adopt various vapour liquid separators, comprises air inlet, Disengagement zone and mozzle; Escape pipe is positioned at the top of tank body and stretches into separator, and by the internal communication of separator and tank body, escape pipe is connected by flange with tank body; Discharge nozzle is positioned at the bottom of tank body; Flash tank is when work, liquid-vapor mixture material is the below spray to spray chamber through spray orifice, liquid in mixed material is because Action of Gravity Field is fallen tank base, the mixed material that is entrained with remaining liq enters flash chamber to carry out through demister, carrying out separation again after flash separation, finally by crossing the further vapor-liquid separation of separator, isolated gas and liquid are discharged from escape pipe and discharge nozzle respectively.
Feed pipe is positioned at the below of tank body and stretches into tank inner chamber, and feed pipe is provided with valve and shower nozzle, and shower nozzle is divided into spray separation chamber and flash chamber by tank inner chamber.
On shower nozzle, be densely covered with spray orifice, spray orifice arranges downwards.
Separator is positioned at tank body top, and separator can adopt various vapour liquid separators, comprises air inlet, Disengagement zone and mozzle.
Escape pipe is positioned at the top of tank body and stretches into separator, and by the internal communication of separator and tank body, escape pipe is connected by flange with tank body.
Demister is positioned at the top of feed pipe, wire packing, consists of.
Adopted technique scheme, the beneficial effects of the utility model are:
Feed pipe stretches into tank inner chamber, and in tank inner chamber, be provided with spray equipment, the liquid-vapor mixture that enters flash tank carries out flash distillation after spray equipment spray, strengthened the flash distillation effect of liquid-vapor mixture material, shower nozzle arranges downwards, the liquid of being convenient in liquid-vapor mixture better relies on gravity fall, and in tank interior, demister and separator is set, and has further improved separating effect.
Therefore, the utility model is compared with existing flash tank and is had outstanding advantage and be: (1) good separating effect (2) foam removal effective (3) exhaust emission is little, conservation
