Embodiment Construction

[0022] Such as Figure 1-2 As shown, the present invention discloses an alcohol extraction device for a dioctyl phthalate production system, including a heating tank, a waste water tower 2, a condenser 3, and a liquid separation tank 4. The top of the heating tank 1 is provided with a waste water tower 2, the top of the waste water tower 2 communicates with the air inlet of the condenser 3 through the first pipeline 51, and the liquid outlet of the condenser 3 communicates with the upper end of the liquid separation tank 4 through the second pipeline 52. connected. The liquid separation tank 4 is provided with a water outlet and an alcohol outlet. The water outlet is located below the alcohol outlet.

[0023] Preferably, the alcohol outlet is in communication with the reactor of the dioctyl phthalate production system.

[0024] Preferably, the condenser 3 is a shell and tube condenser.

[0025] Preferably, the water outlet communicates with the wastewater tower 2 through a...

Abstract

The invention discloses an alcohol extracting device for a dioctyl phthalate production system. The device comprises a heating tank, a waste water tower, a condenser and a liquid separation tank, wherein the waste water tower is arranged at the top of the heating tank; the top of the waste water tower is connected with a material inlet of the condenser; a liquid outlet of the condenser is connected with the upper end of the liquid separation tank; a water outlet and an alcohol outlet are formed in the liquid separation tank; the water outlet is positioned below the alcohol outlet. The alcohol extracting device has the advantages that raw materials are effectively recovered, environment pollution is reduced, and the cost for the post water treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of dioctyl phthalate production, in particular to an alcohol extraction device used in a dioctyl phthalate production system. Background technique [0002] Dioctyl phthalate is a general-purpose plasticizer, mainly used in the processing of polyvinyl chloride resin, and also in the processing of high polymers such as chemical resin, acetic acid resin, ABS resin and rubber, and can also be used in paint making , dyes, dispersants, etc., DOP plasticized PVC can be used to manufacture artificial leather, agricultural films, packaging materials, cables, etc. [0003] Except for cellulose acetate and polyvinyl acetate, it has good compatibility with most industrially used synthetic resins and rubbers. It has good comprehensive performance, good mixing performance, high plasticizing efficiency, low volatility, good low temperature softness, water extraction resistance, high electrical performance, good heat resis...
