How to choose the right equipment?

Core technical parameters are the key to evaluating the quality and production efficiency of equipment, directly determining the service life, production stability and product revenue of the equipment. The following aspects should be given priority attention. The main reactor, also known as the cracking furnace, is the core component of the waste tire oil refining equipment. Its material, structure, wall thickness and insulation performance are of vital importance. In terms of material, Q245R/Q345R boiler steel plates should be preferred, as these plates can withstand temperatures up to 700℃ and are suitable for conventional cracking conditions. If the equipment is in a corrosive environment, 310S stainless steel should be chosen instead of ordinary carbon steel to prevent rapid equipment wear. In terms of structure, the horizontal rotating structure is superior to the vertical flat-bottom structure, as it can achieve more uniform heating, reduce the problem of local overheating and coking, and increase the service life and cracking efficiency of the equipment. The wall thickness should be at least 16mm to ensure the safety of the equipment under high-pressure conditions and avoid potential safety hazards. In addition, high-quality insulation materials can reduce energy consumption by more than 30%, effectively saving operating costs in the long term. When selecting, this aspect should be given priority consideration.

The oil yield and conversion rate are the core indicators for measuring the production efficiency of the equipment. The industry standard level is an oil yield of 35% - 45%, carbon black of 35% - 40%, and steel wire of 10% - 12% from waste tires. These are influenced by factors such as heating temperature, stirring efficiency, and cracking time. The best effect is achieved when the heating temperature is controlled between 350 - 450℃. It should be noted that some manufacturers may falsely claim an oil yield of over 50%, which does not conform to the actual situation in the industry. Investors should make rational judgments to avoid being misled. The automation and control system is related to labor costs and production stability. The basic configuration should include automatic temperature and pressure monitoring and over-temperature and over-pressure alarm functions. Advanced configurations can include PLC/DCS control systems, remote monitoring, and automatic feeding and slag discharge functions. For fully continuous equipment, the installation of such systems can reduce labor input by 80% and significantly enhance production stability.

The choice of heating methods should be based on one's own energy supply situation and environmental protection requirements. Currently, there are mainly three methods: fuel heating, electric heating, and synthetic gas recycling. Fuel heating has a lower cost and is suitable for large-scale production, but it causes relatively high pollution and is suitable for projects with stable fuel supply and moderate environmental protection requirements. Electric heating is clean and environmentally friendly, with precise temperature control, but it has high energy consumption and operating costs, making it suitable for small-scale projects and regions with extremely high environmental protection requirements. Synthetic gas recycling is a standard feature of continuous equipment, which can utilize the synthetic gas produced during the production process as an energy source, effectively reducing operating costs. However, the system is relatively complex and requires a complete purification treatment system, making it suitable for large-scale projects that pursue long-term energy-saving benefits.
