The invention belongs to the chemical field, particularly relates to a waste ionic liquid treatment device, which comprises a waste ionic liquid tank, a horizontal screw centrifugal machine, a clean liquid tank and a dirty oil recovery tank, wherein a discharge port which is arranged on the bottom portion of the waste ionic liquid tank is communicated with a feed port of a screw pump through a valve, a discharge port of the screw pump is communicated with a feed port of a mixer through a pipeline, a discharge port of the mixer is communicated with a feed port of the horizontal screw centrifugal machine through the pipeline, and a liquid outlet of the horizontal screw centrifugal machine is communicated with a top feed port of the clean liquid tank through the pipeline. The waste ionic liquid treatment device treats waste ionic liquid by reacting waste ionic liquid and sodium hydroxide (NaOH) solution, enables components in ionic liquid to generate metal solid slag which are easy to treat to recycle, is safe and environmentally friendly, and puts an end to environmental pollution and safety hidden trouble which are caused because a lot of waste ionic liquid is stored.
Description
(1) Technical field [0001] The invention belongs to the field of chemical industry, in particular to a waste ionic liquid treatment device. (2) Background technology [0002] Alkylation reaction specifically refers to the reaction of isobutane and olefins under the action of a catalyst to obtain isoparaffins. It is a traditional technology in the field of petroleum refining. The product (alkylated oil) has low sulfur, low vapor pressure, and no aromatics. , high combustion calorific value, high octane number and other advantages, it is an ideal gasoline blending component. The traditional alkylation reaction is mainly divided into sulfuric acid alkylation technology and hydrofluoric acid alkylation technology, but both of them have serious problems such as equipment corrosion and environmental pollution that are difficult to solve, which greatly limit their wide application. Promote apps. Ionic liquids are a new class of environmentally friendly liquid materials composed e...
