Description
Technical Field
The invention belongs to the technical field of waste tire treatment, and particularly relates to a system and a method for reducing carbon black ash content of waste tire cracking and recovering Zn.
Background
With the rapid development of economy and industrialization, the number of waste tires is increased sharply, so how to realize the recovery and utilization of waste tire resources has important significance for the sustainable development of circular economy, industrialized ecology and society.
The main products of the thermal cracking of the waste tires are pyrolysis oil and pyrolysis carbon black. The cracking carbon black can be used as tire reinforcing carbon black, pigment and the like after deep processing treatment, and the additional value is greatly improved. ZnO and SiO are often added in the process of manufacturing tires2And sulfur and other chemical assistants, which are enriched and cracked in carbon black with the cracking of waste tyre. The ash content of the cracking carbon black is about 15-20 percent and is far higher than that of the commercial carbon black, and the ash content mainly comprises ZnO and SiO2And inorganic oxide, wherein the content of ZnO is 8-9%. The ash can cover active sites on the surface of the cracking carbon black, so that the cracking carbon black is prevented from being actually in direct contact with rubber molecular chains, and the reinforcing effect of the cracking carbon black is greatly reduced.
There are two methods of reducing soot: the physical separation method and the chemical method are adopted to reduce the ash content at present because the cracking carbon black has a nano-scale structure and complex components, and the physical separation method is difficult to achieve the effect. There are two main processes for reducing ash content by chemical methods: acid (hydrochloric acid, sulfuric acid, nitric acid, etc.) -alkali (sodium hydroxide, etc.); the two methods not only consume a large amount of strong acid and strong base chemicals, but also can not effectively recover Zn, and also can increase the treatment difficulty of subsequent waste water, waste acid, waste alkali and other waste liquids.
Chinese patent CN1206286C discloses a method for producing low ash content carbon black. Heating waste high polymer materials to 350-700 ℃ in inert gas, carrying out thermal cracking carbonization to obtain cracked carbon black, adding inorganic salt, mixing and roasting the cracked carbon black, wherein the roasting melting temperature is 150-480 ℃, the roasting melting time is 30-200 min, the mass ratio of the inorganic salt to the cracked carbon black is 0.1-0.4: 1, the inorganic salt is in a molten state and reacts with metal oxides in the cracked carbon black to generate soluble metal salt, and the low-ash-content carbon black is prepared through the subsequent processes of washing, drying, crushing and grading. The invention needs to add chemicals and add a water washing process, and a large amount of waste water is generated.
Chinese patent CN109705635A discloses a method for deashing and ZnO recovery of waste tire cracking carbon black, comprising the steps of adding cracking slag obtained by cracking waste tires at high temperature into an organic weak acid solution for treatment, filtering the treated solution, washing and drying solid residues obtained by filtering to obtain carbon black with higher purity; and (3) carrying out nitrogen gas stripping treatment on the filtrate obtained by filtering, carrying out solid-liquid separation after the gas stripping treatment, and washing, drying and roasting the obtained solid to obtain ZnO. The method has long process flow, also needs to add chemicals and generates a large amount of waste water.
Most of the existing technologies for reducing the ash content of the cracked carbon black are methods of adjusting the dosage, the type, the adding process and the like of medicaments, the problems of large medicament consumption, large water consumption, complex waste liquid treatment and the like are not solved, and Zn is not efficiently recovered.
