Embodiment 1

[0009] Embodiment 1: Clean petrochemical waste clay with an organic solvent and put it into the chemical cleaning tank (1) according to 1: 0.5-1.5, then stir it slowly for 5-20 minutes, and extract the oil in the clay by pressing and filtering (2) The product only has 5-10% organic solvent and a small amount of oil stain, and most of the oil product and organic solvent have entered the storage tank (10), and then stratified to obtain gasoline and diesel oil and organic solvent respectively. Drop into the saponification tank (3) with 20-30% sodium hydroxide solution and the above-mentioned press filter residue, persist in 20-30 minutes under uniform stirring and then dry the centrifuge (4) with 5-10% The steam (5) of the zinc chloride solution is boiled and activated for 50 minutes, and the regenerated activated clay (9) is newly obtained through drying (6), drying (7), and pulverization (8).

Embodiment 2

[0010] Embodiment 2: Clean the petrochemical clay with an organic solvent and put it into a chemical cleaning tank according to 1: 0.5-1.5, then slowly stir it for 5-20 minutes, and extract the oil in the clay with a squeeze filter method, leaving only 5-10 minutes. % of organic solvents and a small amount of oil, most of the oil and organic solvents have entered the storage tank, and then stratified to obtain gasoline and diesel oil and organic solvents. Use 20-30% sodium hydroxide solution and the above-mentioned press filter residue into the saponification tank, persist for 20-30 minutes under uniform stirring, then use a dry centrifuge, and then use 5-10% zinc chloride solution steam After boiling and activating for 50 minutes, regenerated activated clay is obtained by drying, drying and pulverizing.

Abstract

The invention discloses a method for extracting gasoline and diesel fuel and recovering clay from petrifaction waste clay; the main technical proposal is that: solvent oil extraction, pressure filtration, saponification, activation, centrifugal dehydration, drying, crushing measures are carried out to the petrifaction waste bleaching earth to obtain the gasoline and diesel fuel and regenerative activated clay. The invention provides a method for extracting gasoline and diesel fuel and recovering clay from petrifaction waste clay, which effectively extracts gasoline and diesel fuel and recovers the activated clay; the pollution is eliminated and the value is created, therefore, the method has double benefits.

Description

Technical field: [0001] The invention relates to the technical field of comprehensive utilization of three wastes in the petrochemical industry, in particular to a method for extracting gasoline and diesel from petrochemical waste clay to recover clay. technical background: [0002] At present, the treatment of petrochemical clay is mostly burned in boilers as fuel, so as to obtain some heat energy as much as possible. It is unscientific to do so, and the potential has not been tapped out. According to the analysis of material application theory and end theory, combustion is the lowest and cheapest embodiment of material utilization. Only by using scientific methods to extract the most valuable things inside the material to make them appreciate is a worthwhile approach, and it is also a macroscopic manifestation of the value of materialism. The present invention adopts the means of chemical extraction and regeneration to fully embody the value theory of materials, and organ...
