Abstract

The invention discloses an automatic mineral oil water separation device and process method for a solvent tail gas absorption system and belongs to the technical field of tail gas treatment. The device comprises a desorption tower, a lean oil pump, a heat exchanger, a lean oil cooler, an absorption tower, a rich oil pump, a rich oil heater and a tail gas fan, the bottom of the desorption tower is connected with an inlet d of the heat exchanger through the lean oil pump, an outlet b of the heat exchanger is connected with the absorption tower through the lean oil cooler, and the bottom of the absorption tower is connected with an inlet c of the heat exchanger through the rich oil pump; and an outlet a of the heat exchanger is connected with the top of the desorption tower through the rich oil heater, the tail gas fan is mounted at the top of the absorption tower, and an automatic drainage tank is included and arranged on a pipeline communicated between the lean oil cooler and the absorption tower. The device aims to solve the problems of poor reliability of manual discharge and more human factors of manual discharge of waste water in paraffin oil of the existing tail gas system, realizes automatic discharge of paraffin oil before oil feeding of the absorption tower, and reduces solvent consumption and environmental pollution.

Description

technical field [0001] The invention relates to a device for automatically separating water from solvent tail gas mineral oil, belonging to the technical field of tail gas treatment. Background technique [0002] Vegetable oil production industry leaching oil production is a commonly used oil production process. Solvent consumption occupies a certain proportion in exhaust emissions. For every ton of material produced and processed in the leaching workshop, 2-2.5 kg of air will enter the system, which is called Free gas, currently the paraffin oil absorption and analysis method is widely used in the industry to recover the solvent in the tail gas, reduce production costs and reduce environmental pollution to ensure production safety. Water in paraffin oil will cause emulsification of paraffin oil, which will reduce the solvent absorption efficiency. [0003] At present, the paraffin oil absorption method adopts the negative pressure absorption process. During the analysis pr...
