Municipal domestic waste contains a large number of high calorific value components, and this calorific value will not be effectively utilized if the waste is directly incinerated or filled. Through the existing thermal power plant, thermal power plant, cement plant coupled with power generation and co-disposal, combined with RDF fuel briquette production technology, no landfill, no need to invest in the construction of waste incineration power plant, can be municipal garbage, industrial solid waste, “harmless, minimization, resource, energy” comprehensive utilization of the treatment and application.
MSW
As municipal waste is incinerated directly as a solid fuel without treatment, the following major problems often exist:
- The organic matter in the garbage is extremely perishable, transportation and storage are more difficult;.
- The garbage has a composition and calorific value fluctuations, moisture and ash content and other characteristics, easy to cause combustion instability.
- The waste often contains plastics, salt and other chlorine-containing compounds, high-temperature heating will produce corrosive hydrogen chloride gas, hydrogen chloride emissions can form acid rain, and can corrode metal equipment in the furnace; due to the presence of chlorine-containing compounds, but also may produce highly toxic hazardous substances - dioxins, the formation of a more serious danger to human health;.
- Waste incineration ash usually contains harmful metals, such as mercury, lead, etc., if not properly handled, will also cause secondary pollution of the environment.
Through the above several situations we know that the city's domestic waste needs to be pre-treated in order to apply. The emergence of a kind of garbage-derived fuel that will be effectively pre-treated and molded and processed before entering the furnace, and then incinerated and utilized as a solid fuel, provides a new way of thinking for solving the above problems, and has been applied to municipal garbage, general industrial solid wastes, papermaking wastes, scrap steel mill wastes, textile wastes, leather wastes, rag wastes, waste garments, and other materials.
RDF Fuel Briquette Production Line
Municipal garbage is shredded by twin shaft shredder and fine shredder, and then entered into RDF molding machine, extruded into RDF high-density particles, which are used as fuel for power plants to burn and generate electricity, realizing the reuse of resources. After the RDF production line after processing the garbage derived fuel RDF has a high calorific value, stable combustion conditions, RDF-5 volatile content of more than 75%, moisture content of less than 20% significant advantages, can be a large number of large-scale circulating fluidized bed boilers for blending coupled with power generation, a large number of alternatives to the use of coal-burning fuels, saving a lot of coal-fired fuel costs for the enterprise, but also to ensure that the electric power production of safe, stable and sustainable operation, and emissions fully meet the standard requirements. And the emission fully meets the standard requirements.
RDF Fuel Briquetting Machine Features
- Adopting electromechanical-hydraulic integration technology, with mature structure and stable operation.
- The mold is single independent, easy to replace, convenient and quick.
- With automatic lubrication, electro-hydraulic lubrication device, convenient maintenance.
- With automatic reversing function, it can reverse by itself when overloaded.
RDF fuel briquetting machine working principle and process
Briquetting machine consists of machine base, shroud, feeding port, press wheel, flat mold, discharge port and other parts.
Its working principle is as follows: the material to be pressed should be shredded first, its length 30-60mm is suitable, the moisture content is within the range of 15%-25%, the material will be sent to the feeding port of the briquetting machine through the loading conveyor, the material will be dispersed uniformly to the working area between the pressure wheel and the flat die, the material is forced to be extruded from the flat die in the shape of a block by the rotation of the spindle, which will lead to the rotation of the pressure wheel and the material is forced to fall out of the discharging port.
GEP ECOTECH RDF fuel briquette technology has brought vitality to waste energy and has become a new growth point in the field of waste utilization. It is widely used in coal-fired power plants, thermal power plants, waste incineration power plants, thermal power plants, cement plants and other enterprises, effectively accelerating the transformation and upgrading of electricity, and gradually realizing the green and low-carbon production of electricity, and contributing to energy transformation.
