Abstract

The invention discloses a method of combination and regeneration of waste high molecular materials or co-production of the waste high molecular materials and carbon black, and a device thereof, relating to two technologies of existing thermal cracking and non-thermal cracking of the waste high molecular materials and improvement and combination among various technological branches and also relating to the regeneration process of the waste high molecular materials and the combination of the regeneration process of the waste high molecular materials and the production process of general carbon black and an integration device used in the embodiment thereof; and comminution at normal temperature or the combination of the comminution at normal temperature and various branches of renovated rubber technology and an integration device adopted by the embodiment thereof are also included. The method also provides a treatment proposal for applying mixed fiber to recycling and products thereof, which are characterized in that the mixed fiber and plasticized rubber materials or / and oil materials are matched by the weight percentage of 100:5 to 100:100 to obtain a mixture taking the shape of a felt or a rubber felt or a treated felt. The proposal of the integration device also provides a combination device with fractional efficiency higher than that of the existing fractional process for the granularity of rubber powder only by means of a power screen.

Description

technical field [0001] The invention proposes a combined regeneration process of waste rubber and plastic polymer materials, or a method of combining this process with the production process of ordinary carbon black, and an integrated device used to implement the method; it involves polymer solid waste and ordinary carbon black The technical category of tail gas waste heat utilization in the carbon black production process. Background technique [0002] The regeneration and recycling of waste polymer materials has become an increasingly important industrial category in today's society. The main branches include: the regeneration of waste rubber such as waste tires, the regeneration of waste plastics, etc. [0003] For the regeneration methods of waste rubber, the main branch methods at present are: using closed heating to cut off sulfur, plasticizing processing, that is, reclaimed rubber method, to produce reclaimed rubber products; using crushing processing method to produc...

AI Technical Summary

Problems solved by technology

[0025] g. The current coarse crushing unit machinery that is matched with the shearing grinding disc process and its integrated device cannot process the rubber that will become sticky after being rolled into non-adhesive rubber particles that are finer than 5 mesh, and then crush it to fine The machine supplies sticky rubber and rubber pellets;

[0026] h. The mechanical sieve method is used to classify the finely crushed 20-200 mesh rubber powder, and the efficiency is too low

[0027] 3. Using waste rubber such as waste tires as raw materials to produce reclaimed rubber products, the materials entering the tank for high-temperature plasticization treatment always use rubber powder much coarser than 100 meshes, so that the materials out of the tank must be rolled and thinned. The so-called refining treatment; although this reclaimed rubber process has the advantages of good viscosity, high plasticity and no phase interface between old and new rubber when used in new rubber, it also has the disadvantage that the obtained rubber is not easy to use during revulcanization. Defects such as gas escape from the rubber compound

[0028] 4. Use waste tires as raw materials, process them by pyrolysis, and recover products such as oil, carbon black (slag) and steel wires. This scheme also has shortcomings

First of all, the obtained carbon black is a mixture of lumps, granules, and powders. If it is to be used as a reinforcing agent product for elastomers, it can only be mechanically crushed first, and then ultrafinely crushed to finer than 500 mesh, and then the process route of carbon black powder bagging, this carbon black (slag) treatment scheme makes the enterprises that process waste rubber such as waste tires by pyrolysis all have serious black dust pollution; When processing by the traditional method, the waste tires are broken into large pieces or put into the pyrolysis furnace or tower or tank or rotary kiln as a whole. short

[0029] 5. Plastics are processed by pyrolysis to obtain pyrolysis oil and tar residue products. This method only has a good market for pyrolysis oil, and the current outlet for tar residue is mainly deep burial treatment, which has caused hidden dangers to the environment.

[0030] 6. In addition, after thermal cracking treatment of waste rubber and plastic products, fuel oil, combustible gas, carbon black (slag), and steel wire will be obtained. Fuel, but if the generated amount is too much or too little, the existing disposal method is to vent and ignite or use external heating energy. The market price of combustible gas is not high, and the existing methods of disposing of combustible gas are not enough to make high-value utilization;

[0031] 7. Use hot extrusion processing to produce recycled plastic particle products. This method is only suitable for single and clean materials.

[0039] In the existing technology, the production process of ordinary carbon black and the recycling process of waste rubber and plastic polymer materials are not related to each other. In each individual treatment process, there is no transfer of energy and materials from the production system to the environment. External discharge means that there is excessive consumption of energy and materials in the external environment by the production system
