Abstract

The invention discloses a wastewater lifting device for producing dioctyl phthalate. The wastewater lifting device comprises a horizontal separating tank, a heating tank, a wastewater tower, a condenser and a liquid separating tank, the front end of the horizontal separating tank is provided with a feeding port, the top of the rear end of the horizontal separating tank is provided with an ester returning port, a wastewater discharging port is arranged at the bottom of the rear end of the horizontal separating tank and communicated with the heating tank, the wastewater tower is arranged at the top of the heating tank the top of the wastewater tower is communicated with an air inlet of the condenser, a liquid outlet of the condenser is communicated with the upper end of the liquid separating tank, a water outlet and an alcohol outlet are arranged on the liquid separating tank, and the water outlet is positioned below the alcohol outlet. The wastewater lifting device has the advantages that products and raw materials are effectively recycled, environment pollution is reduced, and subsequent water treatment cost is lowered.

Description

technical field [0001] The invention relates to the technical field of dibutyl phthalate production, in particular to a waste water extraction device for producing dioctyl phthalate. 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 resistance and w...
