Sources and Treatment of Commercial and Industrial Waste

The industrial waste fuel RDF production line is suitable for processing paper products, waste plastics, rags, various textiles, waste rubber, broken leather products, waste wood, and other high calorific value waste.

Industrial waste refers to solid waste generated in machinery, light industry, and other industrial production processes. It generally includes waste paper products, waste plastics, rags, various textiles, waste rubber, broken leather products, waste wood, and other materials with high calorific value. However, direct incineration or landfilling of these wastes wastes resources. Nonetheless, they can be recycled through granulation. The Enpater industrial waste fuel RDF production line aims to crush and sort industrial waste to produce RDF fuel rods for power generation in power plants. Consequently, these fuel rods, denser and with lower combustion losses, supply more heat, making them more valuable for recycling.

Through the crushing pretreatment system, we crush commercial waste to a uniform particle size before incineration for power generation. This process ensures that the waste burns more fully at the rear end, enhancing combustion efficiency and simplifying temperature management in the furnace. Additionally, it effectively controls dioxin production during waste incineration from the source. In some cases, we can utilize the heat generated by incinerating waste to produce electricity and heat. Therefore, implementing reasonable pretreatment before waste incineration can effectively mitigate its hazards and reduce incineration costs.

Domestic waste incineration power generation pretreatment

To generate electricity from domestic waste incineration, we aim to extract the combustible part of the waste into fuel. Through pre-treatment processes such as screening, crushing, separation, fermentation, drying, and processing, we transform municipal solid waste into refuse-derived fuel (RDF) with higher calorific value and more stability. By combining this with the combustion characteristics of the cement decomposition furnace, we realize the technology for disposal and utilization to achieve resource utilization.

RDF Fuel Preparation and Working Principle

Firstly, in refuse-derived fuel (RDF) processing and production technology, we crush domestic waste, sort out the materials, add additives to dry them, and then extrude them to make granular RDF fuel. RDF fuel has the characteristics of uniform size and uniform calorific value. The molding process can increase the calorific value of waste by about 4 times, and it is easy to transport and store.

RDF technology extracts the combustible part of garbage into fuel. The basic principle involves multiple crushing, magnetic separation, and solid waste separation through screening machines, garbage shredders, and airflow separation systems. After selecting the material, we dry it, add additives, and then screen and process the finished product before compressing it into the desired shape to create solid fuel.

Quran RDF fuel pretreatment production line

Solid incineration waste typically requires crushing and sorting. Crushing the waste into a certain particle size not only facilitates incineration but also enhances the sorting process, making it easier to recycle valuable resources.

Quran Machinery’s RDF pretreatment production line integrates crushing and sorting. It mainly consists of a coarse crusher, fine crusher, conveying equipment, and magnetic separation equipment. Developed based on a comprehensive analysis of domestic waste components, the RDF pretreatment production line utilizes the advantages of the GI intelligent monitoring system to conduct crushing and volume reduction disposal of domestic waste.

1 . Quran mechanical hydraulic primary crusher for primary crushing

For RDF garbage-derived fuel, the initial step involves coarse crushing, where large-volume wooden sticks, fibers, plastics, and other components are crushed roughly. This process is conducive to transportation and storage, and it is crucial for the production of RDF fuel.

Moreover, the hydraulic primary shredder plays a vital role in this coarse crushing process. It stands out as one of the mainstream crushing equipment options, known for its high production efficiency in solid waste crushing. This equipment is extensively utilized in various solid waste-crushing processes. The knife roller is directly driven by low-speed, high-torque dual hydraulic motors. Through the interaction between the moving knife and the middle comb, the material undergoes shearing, tearing, and pulling. The hydraulic primary shredder is characterized by its significant crushing force, high output, low noise, and excellent stability.

2. Quran mechanical self-unloading electromagnetic iron remover— Metal Separation

Metal substances constitute recyclable resources, hence the necessity to separate metal objects before incineration. To accomplish this, we employ the self-unloading electromagnetic iron remover. This equipment can eliminate ferromagnetic items that are mixed within bulk non-magnetic materials. Notably, it possesses characteristics such as a large magnetic penetration depth and strong suction power.

In operation, the iron remover detects and retrieves the iron parts mixed within the material. Subsequently, it expels them through the iron unloading belt, thereby achieving automatic separation.

3. Quran Mechanical Fine Crusher—Secondary Crushing

Due to the requirement for incineration particle size, we need to crush domestic waste twice to reduce its volume and facilitate transportation and storage.

Our company’s fine crusher consists of a main shaft, blade, fixed knife, box, feeding system, pushing system, and power system. The interaction between the movable knife and the fixed knife is used to control the discharge particle size through the screen, and the material is shredded, sheared, and extruded to a smaller particle size. This equipment is often used to finely crush various solid wastes and can process materials into smaller particle sizes at one time. It has the characteristics of small discharge particle size, replaceable screen mesh, wide application range of materials, and high efficiency. After secondary fine crushing, the specific surface area of the solid waste increases, thereby improving the stability and thermal efficiency of incineration, thermal decomposition, melting, and other operations.

Benefits of RDF Fuel Incineration Power Generation

Reduction:  After incinerating, we can generally reduce the volume by more than 90% and the weight by more than 80%. Incinerating before landfilling can effectively reduce the occupation of land resources.
Harmless: High-temperature incineration of garbage can eliminate a large number of harmful bacteria and toxic substances and effectively control secondary pollution.
Recycling: The heat generated by waste incineration can be used for power generation and heating, achieving the comprehensive utilization of resources. Waste-to-energy can not only transform waste into treasure and generate electricity but also conserve coal resources.

RDF, short for Refuse Derived Fuel, exhibits characteristics such as high calorific value, stable combustion, easy transportation, easy storage, low secondary pollution, and low emission of dioxins. It finds wide applications in drying engineering, cement manufacturing, heating engineering, and power generation engineering.
SRF stands for solid recovered fuel. Usually refined RDF. Not a waste, but a clean, homogeneous, high-quality, high-calorie fuel that can replace traditional fossil fuels such as coal in power plants or cement plants. In addition, it is an environmentally friendly fuel with only one-quarter of the carbon dioxide emissions of coal and significantly reduces nitrogen oxide emissions.
