Abstract
The invention discloses an organic solvent rinsing tower which is especially used for removing dust from an inert gas and cooling and recycling organic solvents (such as ethanol and hexane) in the gas. The organic solvent rinsing tower comprises a rinsing tower shell, wherein a gas inlet is formed in the side wall at the bottom of the rinsing tower shell, a gas outlet is formed in the top of the rinsing tower shell, the opening of the gas inlet faces to the tangential direction of the inner wall of the rinsing tower shell, an upper spray head, a filling layer, a baffle plate, a bubbling dust removal mechanism and a lower spray head are sequentially arranged between the gas outlet and the gas inlet from top to bottom, the filler of the filling layer is strip-shaped or granular, the bubbling dust removal mechanism comprises a liquid storage tank vertical to the axial line of the rinsing tower shell and a liquid layer located in the liquid storage tank, and minipores are densely distributed on the liquid storage tank. According to the invention, by changing the air intake direction and arranging the filling layer, the baffle plate and the bubbling dust removal mechanism, and the exchange area of the gas and the liquid is increased, so as to quickly reduce the temperature of the organic solvent in the gas, significantly improve the dust removal effect and completely recycle the organic solvent in the gas.
Description
Technical field
The present invention relates to drip washing equipment technical field, particularly one is used for the eluting column of organic solvent (as ethanol, hexane etc.) in inert gas dedusting and cooling gas recovery.
Background technology
Organic solvent eluting column utilizes organic solvent liquid in eluting column and inert gas, the dust impurities in adsorbed gas, reduces the temperature of organic solvent in gas, the organic solvent in gas recovery simultaneously.Eluting column disclosed in prior art uses spraying and dedusting, and dedusting means are single, and in eluting column, the gas speed of gas is too fast, and the exchange area of gas and liquid is little, and dust removing effects is not good enough, and cooling-down effect is poor, can not reclaim organic solvent completely.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of organic solvent eluting column, to reach the exchange area increasing gas and liquid, significantly strengthening dust removing effects, reduce organic solvent temperature in gas rapidly.The object of the organic solvent in complete gas recovery.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of organic solvent eluting column, comprise eluting column housing, described eluting column housing bottom sidewall offers air inlet, top is provided with gas outlet, the opening of described air inlet, towards the tangential direction of described eluting column inner walls, changes original direct air intake into tangent line air intake, can produce first water film dedusting, between described gas outlet and described air inlet, be provided with at least one upper nozzle, packed layer, at least one piece of deflection plate, bubbling dedusting mechanism and at least one lower nozzle from top to bottom successively;
The filler of described packed layer is fine strip shape or graininess;
Described bubbling dedusting mechanism comprises the reservoir arranged perpendicular to described eluting column housing axis and the liquid level being arranged in described reservoir, and described reservoir is densely covered with aperture.
Preferably, described liquid layer thickness is 20 centimetres, and gas is filtered in a liquid again, does second time dedusting.
Preferably, described deflection plate is three pieces, and liquid falls from three layers of deflection plate, and form three heavy-fluid curtains, gas carries out third time dedusting by liquid curtain.
Preferably, described packed layer thickness is 20 centimetres, and gas, by packed layer, carries out the 4th dedusting that rubs with the liquid sprayed.
Preferably, described liquid level is organic solvent layer.
Pass through technique scheme, a kind of organic solvent eluting column provided by the invention is by changing gas inlet direction and setting up packed layer, deflection plate and bubbling dedusting mechanism, reach the exchange area increasing gas and liquid, remarkable lifting dust removing effects, organic solvent temperature in rapid reduction gas, the object of organic solvent in complete gas recovery.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
According to Fig. 1, the invention provides a kind of organic solvent eluting column, comprise the eluting column housing (1) of column type, eluting column housing bottom sidewall offers air inlet (2), top is provided with gas outlet (3), the opening of air inlet, towards the tangential direction of eluting column inner walls, between gas outlet and air inlet, is provided with three upper nozzles (4), packed layer (5), about three pieces deflection plates be crisscross arranged (6), bubbling dedusting mechanism and lower nozzles (8) from top to bottom successively.
Wherein, the thickness of packed layer is 20 centimetres, and filler is fine strip shape or graininess, in order to ensure that gas and organic solvent have larger contact surface, is unlikely to again to cause gas to flow because filler is overstocked not smooth; Bubbling dedusting mechanism comprises the reservoir (71) arranged perpendicular to eluting column housing axis and the organic solvent layer (72) being arranged in reservoir, and reservoir is made by the foraminate steel plate of punching press, and organic solvent layer thickness is 20 centimetres.
The organic solvent that upper nozzle sprays, successively by packed layer and deflection plate, finally drops in reservoir, keeps organic solvent layer thickness.
Because the opening of air inlet is towards the tangential direction of eluting column inner walls, can rotate rising after gas enters eluting column housing, the organic solvent sprayed with lower nozzle in uphill process fully contacts, and carries out dedusting first.
Along with gas constantly inputs eluting column housing, eluting column housing bottom pressure increase, the air through dedusting first can enter in organic solvent layer through the aperture on reservoir cell wall, carry out second time dedusting.
The above-mentioned gas through second time dedusting continues upwards, through liquid curtain (organic solvent liquid falls from deflection plate, forms liquid curtain), carries out third time dedusting.
Filler in packed layer is stained with organic solvent, increases the contact area of organic solvent and gas, gas permeation packed layer, carries out the 4th dedusting, finally arrives gas outlet.
A kind of organic solvent eluting column provided by the invention is by changing gas inlet direction, and set up packed layer, deflection plate and bubbling dedusting mechanism, four dedustings are carried out to gas, reach the exchange area increasing gas and liquid, remarkable lifting dust removing effects, organic solvent temperature in rapid reduction gas, the object of organic solvent in complete gas recovery.
To the above-mentioned explanation of disclosed a kind of organic solvent eluting column embodiment, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
