Can waste pyrolysis equipment handle Acrylic plastic? What is the process flow?
The answer is yes.
Acrylic plastic is a common plastic category that is difficult to degrade and dispose of after being discarded. The use of thermal pyrolysis technology to process acrylic plastic is a very environmentally friendly and economically valuable way. The principle of the entire process is to heat acrylic plastic under anaerobic or hypoxic conditions to decompose it into smaller molecules. This process can convert waste acrylic plastic into plastic oil, and the calorific value of the produced oil can reach 11,000. For large calories, the oil quality is relatively high;
Waste Pyrolysis machine designed for acrylic plastics on the market today is uneven, and the price and quality of the oil obtained are also uneven. Let me explain to you the specific process of the pyrolysis equipment designed by our ODIFEI Company for acrylic plastics.
The first step: raw material pretreatment
If the pyrolysis raw material contains water, it is recommended that the raw material be dehydrated in the early stage, which can greatly shorten the entire pyrolysis cycle; the acrylic can also be crushed or cut into appropriate sizes to increase the number of charges and improve the pyrolysis efficiency;
Step 2: Loading
You can use an automatic feeder or select appropriate conveying equipment according to the characteristics of the material to load the material into the cracking reactor; due to the particularity of the raw materials, our Oudi Fei company will set up a coke clearing device for the acrylic plastic cracking reactor. , to extend the service life of the cracking reactor;
Step Three: Heating and Cracking
After the charging is completed, open the cracking kettle heating system to heat the cracking reactor. The heating raw materials can be selected according to your actual situation. Most of the ones on the market now choose fuel oil for heating.
The heated acrylic plastic molecular chain breaks, a thermal cracking reaction occurs, and oil and gas are generated;
Step 3: Dewaxing
Plastic oil is different from tire oil in that it produces wax. Before the oil and gas are cooled, it must be dewaxed to prevent the back pipeline from being blocked and reduce the number of equipment maintenance times;
Step 4: Oil and gas cooling and collection
The dewaxed oil and gas are cooled by the cooling system, liquefied into oil, and stored in the oil tank.
Step 5: Exhaust gas and flue gas treatment
With the generation of oil and gas, a part of non-condensable gas will be produced. This part of the gas will pass through the safety water seal and the flue gas pipe, and then flow back into the gas lance to heat the furnace and reuse the waste gas to reduce the operating cost of the equipment;
The flue gas generated during the heating process passes through two dust removal devices to meet the emission standards and is discharged into the air.
Step 6: Collection of Carbon Black
After the cracking is completed, the cracking reactor is cooled to a certain temperature, and the slag discharge device is opened to discharge the carbon black;
The acrylic plastic pyrolysis equipment designed by ODFcompany not only converts raw materials into energy and products with economic value, but also pays attention to the environmental protection benefits and economic value of the equipment.
