Description

TECHNICAL FIELD

[0001] The present application relates to the field of organic waste salt treatment, in particular to an industrial organic waste salt oxidation treatment method. BACKGROUND

[0002] Industrial waste salt is mainly derived from industrial waste salt containing organic matter and other toxic salt-containing waste liquid and solid generated in the production process of chemical industry, pharmaceutical industry, agricultural chemical industry and coal chemical industry. The main salt production links include reaction salt generated by mother liquor (process wastewater), neutralization salt generated by acid-base chemical reaction, salt-out salt, and salt mud generated by distillation residue. The organic matter in waste salt is complex, with characteristics such as variety, complexity, multiple sources, high treatment cost, and great environmental harm. In recent years, the amount of waste salt produced in China has been increasing, and it is estimated that the annual production will exceed 300 million tons.

[0003] In 2021, the National Hazardous Waste List officially included distillation and reaction residues, waste mother liquor, and reaction tank and container cleaning waste liquid in various production processes. Improper treatment of waste salt will directly pollute surface water, groundwater, and soil. At present, waste salt is generally treated by building a centralized storage library, which faces high storage and management costs, which enterprises cannot afford, and has become a "neck" problem restricting the development of enterprises. At the same time, industrial waste salt is also an important chemical raw material. If the by-product waste salt can be recycled and used as an industrial raw material, not only can it eliminate its pollution to the environment, but also can make full use of salt resources and realize the recycling and cyclic utilization of by-product salt. Under this background, the harmless and resource utilization of waste salt has become the inevitable way of waste salt disposal, and the main factor restricting its large-scale development is the removal of organic matter in waste salt.

[0004] A kind of industrial waste salt harmless disposal resource utilization method (application number: CN202210697600.2) first uses dry feeding unit to send industrial waste salt into pyrolysis unit, heats and warms industrial waste salt, warms it to 300-600℃, so that water in industrial waste salt evaporates, macromolecular organic matter decomposes, and high-temperature gaseous mixture is produced. After spraying cooling and purification treatment, it can be used as boiler fuel, and high-temperature steam produced by the boiler is used as heat source for evaporation crystallization unit; The solid residue produced by pyrolysis is dissolved and filtered, and the obtained liquid is sent into the evaporation crystallization unit after impurity removal to obtain industrial refined salt, and the evaporated water is condensed and can be returned to the boiler or used as circulating water.

[0005] The patent discloses an industrial waste salt harmless treatment method (application number: CN202210434295.8), which comprises the following steps: putting industrial waste salt, conversion aids and auxiliary materials into a high-temperature environment to cause high-temperature oxidation of organic matters in the industrial waste salt, harmless decomposition, melting of soluble alkali metal salt, alkali earth metal salt and heavy metal and conversion aid components, crystal disintegration, melting, formation of mineral precursor, solid solution reconstruction and low-temperature eutectic substance generation, and finally obtaining a dense solid solution product after quenching and cooling of the generated liquid melt; the toxic organic matters in the industrial waste salt are completely decomposed at high temperature, the precursors of the toxic substances of dioxins POPs that cannot be avoided by conventional high-temperature treatment are eliminated from the source, the soluble inorganic salt components and heavy metals in the industrial waste salt are sealed in the dense solid solution material network structure, and there is no environmental dissolution risk, and the resources can be utilized.

[0006] At present, the industrial waste salt is mainly treated by high-temperature incineration. Due to the limitation of the melting point of the waste salt, the temperature of the high-temperature calcination section can only be controlled at 500-600 DEG C, so that part of the organic matters in the waste salt after calcination will remain in the salt slag. Part of the organic matters may not be removed in the high-temperature calcination section due to uneven heating in the calcination furnace. SUMMARY

[0007] To solve at least one problem in the above background art, the present application provides an industrial organic waste salt oxidation treatment method, which uses an oxidizing agent to remove the industrial organic waste salt, is simple in process, green and environmentally friendly, and does not increase the discharge of three wastes.

[0008] An industrial organic waste salt oxidation treatment method comprises the following steps:

[0009] According to the mass fraction, 100-180 parts of low-content organic waste salt are put into a grinder to be ground into 20-80 mesh powder, then added into 140-200 parts of water, stirred and mixed uniformly to prepare a slurry, and then a pH regulator is used to adjust the pH value of the slurry; the prepared slurry is slowly added into an oxidation reactor and an oxidizing agent is introduced, the slurry adding time is 30-60 min; after the slurry is added completely, the reaction is continued for 20-30 min, then the reaction is completed, the discharge is carried out, the temperature is lowered to 20-30 DEG C, and the insoluble salt is filtered out, the filtrate is evaporated and crystallized to obtain recovered salt, and the oxidation treatment of the industrial organic waste salt is completed.

[0010] Preferably, the pH value regulator is sodium hydroxide or sulfuric acid solution with a mass percentage concentration of 10%-20%.

[0011] Preferably, the pH value is controlled at 3-5.

[0012] Preferably, the oxidizing agent is selected from ozone, hydrogen peroxide gas or oxygen.

[0013] The preferred technical solution is that the aeration amount of the oxidizing agent is 10-18 g / h·L.

[0014] The preferred technical solution is that the reaction temperature of the oxidation reactor is 40-60℃.

[0015] The preferred technical solution is that the oxidation reactor contains a synergist, and the synergist is a manganese / ferrocene organic metal framework material, which is prepared by generating a metal complex of allyl betadex and manganese chloride, and then reacting with 1,1'-diaminoferrocene and 0.5-3.3 parts of ethylenediamine hydrobromide to generate an amino-ene addition response.

[0016] The preferred technical solution is that the synergist manganese / ferrocene organic metal framework material is prepared by the following method:

[0017] Step 1: According to the mass fraction, 5-10 parts of allyl betadex, 1-3 parts of manganese chloride, 100-120 parts of organic solvent are added into the stirring kettle, and stirred for 30-60 min;

[0018] Step 2: 0.005-0.06 parts of 1,1'-diaminoferrocene, 0.5-3.3 parts of ethylenediamine hydrobromide, and 2-5 parts of potassium hydroxide are added, and stirred for 100-150 min, and the organic solvent is removed by distillation;

[0019] Step 3: Then transfer to a reaction kettle made of polytetrafluoroethylene, constant temperature reaction for 10-15 h, take out and cool to room temperature, dry, get manganese / ferrocene organic metal framework material.

[0020] The preferred technical solution is that the organic solvent is selected from ethanol, dimethylformamide, acetone, chloroform or cyclohexane.

[0021] The preferred technical solution is that the reaction temperature of step 1 is 25-35℃, the reaction temperature of step 2 is 50-65℃, and the reaction temperature of step 3 is 100-110℃.

[0022] The reaction mechanism is as follows:

[0023] In the reaction system, the manganese-containing metal complex can provide the required oxygen atom, and then produce manganese oxide catalyst and free radicals. Then, ferrocene can act as an electron transfer reagent to participate in the electron transfer of the reaction system, promote the generation of free radicals. And the hydrobromide functional group can react with organic molecules in waste salt, increase the displacement degree of organic molecules and the electrophilicity of reactants, accelerate the activation of catalyst, so as to make the whole oxidation treatment reaction more efficient.

[0024] Compared with the prior art, the application has the following technical effects: due to the limitation of the melting point of the waste salt itself, the temperature of the high-temperature calcination section can only be controlled at 500-600 DEG C, resulting in that part of the organic matter which is not easy to decompose will be left in the salt residue after the waste salt is calcined. Part of the organic matter can not be removed in the high-temperature calcination section due to uneven heating in the calcination furnace. The manganese / ferrocene organic metal framework material synergist can remove the organic matter in the high-temperature calcination section. DETAILED DESCRIPTION
