A kind of benzyl benzoate oil residue processing device and method thereof

Abstract

A benzyl benzoate oil residue treatment device and method thereof, comprising an oil residue heating tank, a mixing tank, a screw pump, a plate and frame filter press, the top of the oil residue heating tank is connected to the oil residue pipe through the oil residue inlet, The bottom of the oil residue heating tank is connected to the oil residue discharge pipe through the oil residue outlet, and the mixing and stirring tank is connected to the discharge pipe through the bottom discharge port; the oil residue discharge pipe and the discharge pipe are connected in parallel to the screw respectively The input end of the pump is connected to the top of the transfer tank, the output end of the screw pump is connected to the plate and frame filter press, the bottom of the plate and frame filter press is connected to a collection tank, and the top of the collection tank is provided with a liquid outlet, and the liquid outlet The outlet is connected to the top of the transfer tank through the liquid outlet pipe, and the top of the transfer tank is also provided with a liquid discharge port. The liquid discharge port is connected to the input end of the transfer pump through the liquid discharge pipe, and the output end of the transfer pump is respectively connected to the settling The top inlet connection of tank and mixing tank. The invention collects available materials in the oil residue for reproduction and saves production cost.

Description

technical field [0001] The invention relates to the field of waste treatment in industrial production, in particular to a benzyl benzoate oil residue treatment device and a method thereof. Background technique [0002] Benzyl benzoate can be used as a plasticizer, a solvent for drugs, artificial musk, vanillin and other fragrances, a floral fragrance fixative, etc. There are many methods for synthesizing benzyl benzoate, but the method of extracting benzyl benzoate from the leftovers of benzaldehyde produced by oxidation of toluene to benzoic acid or dibenzyl ether has the advantages of low cost, energy saving and emission reduction. In the method for extracting benzyl benzoate from the leftovers, soda ash and water used in the rectification and neutralization sections of the leftovers will all bring in solid impurities, benzyl benzoate and water to form oil residue. Oil residue solid waste needs to be sent to a qualified hazardous waste treatment institution for centralize...

There are many methods for synthesizing benzyl benzoate, but the method of extracting benzyl benzoate from the leftovers of benzaldehyde produced by oxidation of toluene to benzoic acid or dibenzyl ether has the advantages of low cost, energy saving and emission reduction. In the method for extracting benzyl benzoate from leftovers, soda ash and water are used in the rectification and neutralization sections of leftovers, all of which will bring in solid impurities, benzyl benzoate and water to form oil residue

Oil residue solid waste needs to be sent to a qualified hazardous waste treatment institution for centralized treatment, which is costly and difficult
