Background
In industrial production, an organic solvent recovery apparatus is used for recovering organic solvents (such as various solvents including toluene, xylene, acetone, butanone, cycloethanone, methyl acetate, ethyl acetate, butyl acetate, dichloromethane, trichloroethylene, tetrachloroethylene, diethyl ether, petroleum film, rubber, paint, gasoline and the like) from solvent-containing exhaust gas. The recovered liquid solvent can be repeatedly utilized, the production cost is reduced, meanwhile, the waste gas pollution is effectively prevented, and the environment is fundamentally protected.
Methylene chloride is a colorless, transparent, heavier than water, volatile liquid, slightly soluble in water, and miscible with most organic solvents. In industrial production, dichloromethane is mainly used in the fields of film production and medicine. It is used as reaction medium in pharmaceutical industry and as solvent in film production. Furthermore, the use of methylene chloride as an extractant is becoming more widespread. However, dichloromethane is toxic and harmful to human body after inhalation, so dichloromethane cannot be directly discharged, and dichloromethane usually needs to be recycled. By recycling the dichloromethane, not only is the environment-friendly effect facilitated, but also the production cost is saved or new economic values can be generated.
For example, in the invention application with application number CN201611003175.3, a method for recovering dichloromethane from waste gas is disclosed, which comprises the following steps: condensing the discharged waste gas containing dichloromethane; discharging the waste gas containing dichloromethane after condensation and separation into a molecular sieve adsorber; introducing water vapor into the molecular sieve to desorb dichloromethane; and condensing the desorbed dichloromethane and steam mixed vapor through a three-stage condenser to obtain a mixture of dichloromethane and water, and standing and layering to obtain dichloromethane. In the above-mentioned recovery treatment of methylene chloride, a mixed solution of methylene chloride and water is generated, and it is necessary to separate and recover methylene chloride from the mixed solution by a certain method. In production, a square separation tank is generally used, and separation is carried out by utilizing the gravity separation principle. However, the liquid in the square separation tank has slow flowing speed and short retention time, which is not beneficial to the separation of the liquid and has lower efficiency.

Wherein the first side partition 6 and the second side partition 6' are respectively perpendicular to the middle partition 5. The height of the middle partition board 5 is less than the height of the four side boards, and the height of the middle partition board 5 is greater than the height of the first side partition board 6 and the second side partition board 6'. One side of the middle partition board 5 is connected to the middle of the first side board 11, and a gap is arranged between the other side of the middle partition board 5 and the third side board 13, and the width d of the gap is less than 15 mm. Both sides of the first side partition 6 are connected to the second side plate 12 and the middle partition 5, respectively. Both sides of the second side partition 6' are connected to the middle partition 5 and the fourth side plate 14, respectively. Liquid passages are respectively provided at the bottoms of the first side partition 6 and the second side partition 6'.
A liquid inlet 2 and a top liquid outlet 3 are arranged on the first side plate 11, the liquid inlet 2 and the top liquid outlet 3 are respectively arranged at two sides of the middle partition plate 5, the setting height of the top liquid outlet 6 is smaller than that of the liquid inlet 2, and the setting heights of the two can be close; a bottom outlet 4 is provided in the region of the bottom plate 10 near the top outlet 3.
