Background technology
Chemical industry is the indispensable pith of national product, in Chemical Manufacture, is used for that gas-liquid separation, product are purified or the gas-liquid separation equipment right and wrong that reclaim a kind of chemical industry equipment of usefulness usually.The most frequently used gas-liquid separation equipment is a flash tank.Plasticizer is a kind of very important chemical auxiliary agent, in the production of plasticizer part kind, after esterification step finishes, because material reaction needs the excessive alcohol of part, so, contain part alcohol, ester and a large amount of heat energy in the material that has reacted, need to enter next process after the cooling, directly not only waste energy, also can cause a large amount of wastes of water resource with water for cooling.General plasticizer production producer adopts direct falling temperature method or flash distillation dealcoholysis method to esterification terminal point material, and flash tank is generally adopted in the flash distillation dealcoholysis.But traditional flash tank operation principle is a high-temperature material enters flash tank by inlet along the tank body tangential direction, and in the rotation of centrifugal action lower edge jar inwall, when material pressure descended, the steam that flashes off alcohol was discharged from tank body top.There is the not thorough problem of vapor-liquid separation in this flash tank, and energy recovery is insufficient, and the alcoholic lactone content that reclaims is higher, has promptly influenced the quality of the alcohol that reclaims, and causes certain product to run off again.
Summary of the invention
Technical problem to be solved in the utility model is: at the deficiency that prior art exists, provide a kind of and can make full use of the high successive flash vaporization jar of gas purity that the flash separation of liquid self heat energy, gas-liquid separation effect are good, reclaim.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of successive flash vaporization jar, comprise that sidewall is provided with the tank body that inlet, bottom are provided with liquid outlet, be provided with the vaporization filler in the described tank body, described vaporization filler is divided into the flash chamber that is positioned at the top with tank inner chamber and is positioned at the fluid reservoir of below, described inlet is arranged on the tank body bottom and is positioned at described flash chamber, in flash chamber inlet above be provided with the gas-liquid separation filler, the top of described gas-liquid separation filler is provided with wire mesh demister.
As a kind of improvement, described inlet is entered by the tank body center, and in tank body, being provided with liquid distribution trough, described liquid distribution trough comprises a feed tube that is communicated with inlet and is arranged on some arms of feed tube both sides, is evenly equipped with some fluid holes that upwards are provided with on the described arm.
Wherein, described feed tube and some arms of being arranged on the feed tube both sides all are positioned on the same cross section of tank body.
As a kind of preferred, the total sectional area of described some fluid holes is less than the sectional area of described inlet.
As further improvement, described fluid reservoir to liquid outlet place has a diameter to shrink.
The volume of described flash chamber is greater than the volume of described fluid reservoir.
Wherein, described gas-liquid separation filler is the orifice plate filler, and described vaporization filler is orifice plate filler or wire packing.
Owing to adopted technique scheme, the beneficial effects of the utility model are:
1, the utility model is owing to be provided with the vaporization filler in the successive flash vaporization jar, vaporization filler top is provided with gas-liquid separation filler and wire mesh demister successively, mixed material makes full use of self heat energy, reaching effective with liquid material in flash chamber after a large amount of flash distillations separates, liquid material relies on deadweight to fall, in the tank body bottom when the overflash filler, form the thin feed liquid layer of one deck at the vaporization filling surface, make a spot of gas further evaporation again that contains in the liquid material, reach the purpose that gas-liquid is further vaporized and separated, steam by the gas-liquid separation filler after, a spot of air foam of wherein carrying secretly is thoroughly removed through the silk screen demister, improve the purity of isolated gas, reduced the loss of fluid product.
2, inlet of the present utility model is provided with liquid distribution trough in tank body, liquid distribution trough is distributed with some fluid holes on the tank body cross section, and the total sectional area of fluid hole is less than the sectional area of described inlet, therefore the high temperature mixed liquor that has pressure can spray to tank body top uniformly through some fluid holes, has strengthened the flash distillation effect of mixed liquor.
3, the utility model fluid reservoir to liquid outlet place has a diameter to shrink, and makes the easier automatic outflow of isolated liquid material to enter next procedure.
4, the volume of the utility model flash chamber more helps improving the flash distillation effect of mixed liquor greater than the volume of described fluid reservoir.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure cutaway view of the utility model embodiment.
Fig. 2 is the cutaway view at A-A place among Fig. 1.
Among the figure, 1. tank body; 11. inlet; 12. liquid outlet; 13. gas outlet; 2. vaporization filler; 3. flash chamber; 4. fluid reservoir; 41. diameter shrinks; 5. liquid distribution trough; 51. feed tube; 52. arm; 53. fluid hole; 6. gas-liquid separation filler; 7. wire mesh demister.
The specific embodiment
As depicted in figs. 1 and 2, a kind of successive flash vaporization jar, comprise that sidewall is provided with inlet 11, the bottom is provided with liquid outlet 12, top is provided with the tank body 1 of gas outlet 13, be provided with vaporization filler 2 in the described tank body 1, described vaporization filler 2 is divided into flash chamber 3 that is positioned at the top and the fluid reservoir 4 that is positioned at the below with tank inner chamber, and described fluid reservoir 4 to liquid outlet 12 places have a diameter to shrink 41.Described inlet 11 is arranged on tank body 1 bottom and is positioned at described flash chamber 3, described inlet 11 is entered by tank body 1 center, and in tank body 1, be provided with liquid distribution trough 5, described liquid distribution trough 5 comprises a feed tube that is communicated with inlet 11 51 and is arranged on some arms 52 of feed tube both sides, is evenly equipped with some fluid holes 53 that upwards are provided with on the described arm 52.In flash chamber 3 inlet 11 above be provided with gas-liquid separation filler 6, the top of described gas-liquid separation filler 6 is provided with wire mesh demister 7.
