Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0019] according to figure 1 , the present invention provides an organic solvent elution tower, comprising a cylindrical leaching tower shell (1), an air inlet (2) is opened on the bottom side wall of the leaching tower shell, and an air outlet (2) is provided on the top ( 3), the opening of the air inlet faces the tangential direction of the inner wall of the elution tower shell, and between the air outlet and the air inlet, there are three upper nozzles (4), a filling layer (5), and three nozzles from top to bottom. A baffle (6), a bubbling dedusting mechanism and a lower nozzle (8) are arranged staggered up and down.

[0020] Among them, the thickness of the filling layer is 20 cm, and the filling is in the form of thin strips or granules to ensure a large contact surface ...

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 [0001] The invention relates to the technical field of rinsing equipment, in particular to a rinsing tower used for dedusting inert gas and cooling organic solvents (such as ethanol, hexane, etc.) in recovered gas. Background technique [0002] The organic solvent leaching tower uses the organic solvent liquid in the leaching tower to contact with the inert gas to absorb the dust impurities in the gas, and at the same time reduce the temperature of the organic solvent in the gas to recover the organic solvent in the gas. The leaching tower disclosed in the prior art uses spray dust removal, the dust removal method is single, the gas velocity in the leaching tower is too fast, the exchange area between gas and liquid is small, the dust removal effect is not good, the cooling effect is poor, and the organic waste cannot be completely recovered. solvent. Contents of the invention [0003] In order to solve the above technical problems, the present invention p...
