Description
Technical Field
The invention belongs to the field of harmless treatment of hazardous wastes, and particularly relates to a harmless treatment device for high-sulfur and high-chlorine high-risk hazardous wastes.
Background
The list of hazardous waste, 2021 edition, specifies solid waste (including liquid waste) having one of the following conditions, as included in the list:
(one) having one or more hazardous characteristics of toxicity, corrosiveness, flammability, reactivity, or infectivity.
And (II) the hazardous property is not excluded, the harmful influence on the ecological environment or the human health is possibly caused, and the management according to the hazardous waste is required.
The distillation residue belongs to HW11 category of hazardous waste records, and is mainly from the production fields of dye production, medicines, pesticides and the like. Distillation residues can cause environmental pollution if not properly disposed of because they are not of reuse value and have hazardous components.
For burning dangerous wastes, the prior treatment technology adopts a high-temperature thermal treatment technology, wherein the rotary kiln high-temperature burning treatment is most widely used due to the advantages of high burning temperature, high burning efficiency, low discount rate after treatment and the like. Before disposal, the hazardous waste needs to be combined to control indexes such as calorific value, total sulfur, total chlorine and total fluorine of the hazardous waste entering the incinerator, so as to ensure the stability of the working condition of the incinerator and the standard reaching of the flue gas.
The distillation residue is in liquid state at normal temperature and is solidified at low temperature. Has pungent smell, strong acidity, no oxidability, acid fog when meeting water, and heat and sparks in the crushing process. The distillation residue may contain methylene chloride and phosphorus pentoxide. The calorific value is about 12830J/g, the total chlorine is about 8 to 13 percent, and the total sulfur is about 5 percent. The distillation residue has high sulfur and chlorine content, and the feeding pit can smoke, the crushing process can generate heat and spark is produced. At present, the packaging bag is packaged into 25kg small bags, and the feeding interval is half an hour. Although the distillation residue can be slowly disposed of by subpackaging, the following problems still exist:
firstly, after the materials are divided into 25kg small bags, the excessive CO and the instantaneous SO2 are caused after the materials are fed, and the excessive CO and the excessive SO2 are easily caused due to poor control;
and (II) because the distillation residues react with water vapor in the feeding channel of the rotary kiln to generate a large amount of hydrochloric acid, the hydrochloric acid volatilizes to corrode the water cooling jacket.

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in FIG. 2, the harmless disposal method of the high-sulfur and high-chlorine high-risk hazardous waste comprises the following steps:
s1, dissolving the dangerous waste into one of water, sodium hydroxide, glacial acetic acid and ethanol;
and S2, absorbing the tail gas generated after dissolution.
Dissolving and diluting pure chemicals: aiming at the distillation residues solidified at low temperature, firstly mixing the distillation residues with water, sodium hydroxide, glacial acetic acid and ethanol to see whether the distillation residues can be dissolved or not, and the reaction and heat release conditions in the dissolving process; directly mixing the distillation residues which are liquid at normal temperature with water, sodium hydroxide, glacial acetic acid and ethanol, observing the reaction and heat release conditions in the dissolving process, and determining which chemical substances are more suitable for mixing and dissolving the distillation residues.
And (4) conclusion: the distillation residues can be dissolved in water, sodium hydroxide, glacial acetic acid and ethanol, wherein the distillation residues can be completely dissolved in the sodium hydroxide and the glacial acetic acid, part of the distillation residues are dissolved in the water, and suspended matters are generated after the distillation residues are dissolved in the ethanol; the temperature rise phenomenon exists in the process of dissolving in water, sodium hydroxide and ethanol, and the temperature rise phenomenon does not occur obviously when dissolving in glacial acetic acid. Meanwhile, the pH value of the distillation residue after the sodium hydroxide is dissolved can reach 4-5, and the corrosion to equipment can be reduced. For the high-sulfur chlorine high-reactivity distillation residue, a sodium hydroxide solution can be adopted for dissolving, and the operation condition and the personnel safety are ensured by controlling the reaction temperature in the dissolving process and timely collecting and disposing the acid gas in the dissolving process through a negative pressure device.
Liquid waste dissolution and dilution: as can be seen from the above, it is also possible to select hazardous waste such as developer (containing sodium hydroxide as a main component) and further perform a dissolution dilution test, thereby achieving the effect of "waste by waste". 2g of the distillation residue were dissolved in 20ml of a developer which completely dissolved the distillation residue, the dissolution process being exothermic. Wherein, the developer is strong alkaline pH about 12, is nonflammable, and has no total sulfur and total chlorine detected.
And (3) detecting a dissolved diluent: and detecting indexes such as heat value, total sulfur, total chlorine and the like of the dissolved and diluted distillation residues, determining the mixing proportion, and ensuring that the mixed and dissolved distillation residues meet the furnace entering compatibility requirement. Wherein the compatibility requirement of entering the furnace is that the heat value is 2900J/g, the total sulfur is within 2.5 percent, and the total chlorine is within 3 percent. The calorific value after dissolution and dilution is 2400J/g, the total sulfur cannot be detected, and the total chlorine is 1.38%. The dissolved distillation residue can meet the requirement of entering the furnace, obviously reduces the corrosion to equipment and ensures that the incineration tail gas reaches the standard and is discharged.
Tail gas absorption: because distillation residue has strong irritability and can produce acid gas in the dissolution dilution process, so dissolve the dilution process and need go on in airtight cover, and operating personnel need wear full face guard and protective clothing simultaneously, acid and alkali resistance gloves etc.. The harmless disposal device for the high-sulfur and high-chlorine high-risk hazardous waste is shown in figure 1 and comprises a sealing cover 1, an air suction pipeline 2 and a dissolving and diluting tank 3. The sealing cover 1 is sleeved on the periphery of the dissolving and diluting tank 3. An air suction pipeline 2 is arranged above the sealing cover 1, and the air suction pipeline 2 is connected with a tail gas treatment component (not shown). Dissolving agent is added into the dissolving and diluting tank 3, then distillation residues are added, and generated acid gas is sucked and removed through the air suction pipeline 2 and enters a tail gas treatment component (not shown) for treatment.
The tail gas treatment assembly can comprise a UV photolysis mechanism, a chemical washing tower and an activated carbon adsorption mechanism which are connected in series, wherein the UV photolysis mechanism comprises an ultraviolet lamp and a nano titanium dioxide catalyst. The nanometer titanium dioxide catalyst absorbs light energy to generate electrons, and the electrons react with moisture and oxygen adsorbed on the surface of waste gas to generate alkyl free radicals (OH-) and superoxide ion free radicals (O2-O-) with very active oxidability, so that various organic waste gases, such as benzene, ammonia, nitrogen oxides, sulfides and other VOC organic and inorganic substances, can be reduced into carbon dioxide, water and other harmless substances under the photocatalytic oxidation effect, and the odor disappears at the same time. The chemical washing tower is a packed tower structure, and prepared 30% sodium hydroxide washing liquid is sprayed into the chemical washing tower from the upper part of the chemical washing tower and then absorbs acid gas in the chemical washing tower. The activated carbon adsorption mechanism 23 is composed of an activated carbon fiber module, and the activated carbon fiber has a large specific surface area, so that organic gas which cannot be photolyzed and catalyzed by UV can be further adsorbed.
In summary, the harmless treatment device and method for high-sulfur and high-chlorine dangerous waste in the embodiment perform harmless pretreatment on the distillation residues to reduce the treatment risk. A number of advantages result: (1) the corrosion of the high-sulfur chlorine hazardous waste to equipment and a water-cooling jacket after entering the furnace can be avoided; (2) the distillation residue after dissolution and dilution can meet the requirement of furnace entering control, and the tail gas of an incineration system is ensured to be discharged up to the standard; (3) increasing personnel and equipment safety of the disposal process.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and implement the invention, and not to limit the scope of the invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the scope of the present invention.
