Workflow and advantages of domestic waste treatment production line

The production line for sorting and processing household waste utilizes advanced technology to finely sort and process waste, achieving resource utilization and harmless treatment. This production line has the characteristics of high efficiency, environmental protection, energy conservation, and high recycling rate, and plays an important role in urban cleanliness and sustainable development. At the same time, the operating cost of the production line is relatively low, but it also faces challenges such as high equipment procurement costs and operational maintenance. With the continuous innovation and improvement of technology, the production line for sorting and processing household waste is expected to become an important tool for promoting urban environmental protection development.

1. The workflow of the household waste screening and treatment production line

After being transported by specialized vehicles to the treatment facilities, household waste first enters a closed unloading space, which is equipped with photoelectric switches or radar monitoring systems and video monitoring equipment, and can automatically open or close roller shutter doors according to real-time scenarios. Subsequently, the garbage transport vehicle began to automatically unload the garbage. During the operation of the unloading program, the sterilization and disinfection device and negative pressure deodorization system were synchronously activated to carry out deep level harmless treatment of the garbage.

After this step, the household waste is coordinated by the plate feeder and the conveyor belt to be sent to the first stage coarse crusher feeding port of the waste pretreatment system. During the bag breaking process, the particle size of the waste is reduced to below 250mm. After the first stage of crushing, the garbage is transported again to the drum screen through a conveyor belt. At this stage, an iron remover is installed on the belt to screen out the iron (magnetic) substances contained in the household garbage. The entire magnetic separation process is in a closed state.

The drum screen divides garbage into two categories according to size: large pieces of garbage larger than 80mm (on screen) and small pieces of garbage smaller than 80mm (off screen). Large pieces of garbage enter the air separator through conveying equipment, which divides them into two categories: light and heavy materials. Among them, heavy substances such as stones, glass, concrete, etc. will be transported to specific locations for landfill; Light substances such as paper, plastic, and other combustible materials enter the secondary crusher for crushing, and during this process, iron substances are separated again through the iron remover. The remaining materials are processed into waste derived fuel (RDF fuel).

As for the screened material smaller than 80mm through the drum screen, the remaining heavy material will also be transported to the designated location for landfill after being separated from the iron material by the iron remover.

2. Characteristics and functions of the screening and treatment production line for household waste

In the face of China's proposed goals of harmless, reduced, resource-based, and industrialized waste treatment, Zhongcheng Intelligent Environmental Protection Company, with its rich experience and professional strength in waste treatment, provides a one-stop waste sorting center overall solution from scheme design, equipment manufacturing, installation and commissioning to professional and intelligent operation and maintenance services. Based on the actual situation of each project and the composition of household waste, select a suitable scale of waste treatment production line, scientifically configure various types of waste treatment equipment, achieve significant improvement in resource utilization rate, bring good social, environmental and economic benefits, and effectively promote the development of comprehensive treatment of household waste towards industrialization.

With the acceleration of urbanization, the production of household waste has sharply increased. How to effectively transform these wastes and reduce the pressure on the environment has become a major issue that urgently needs to be solved. The household waste sorting production line is an effective solution to this problem. As a highly integrated processing system, the household waste sorting production line aims to accurately sort mixed household waste for subsequent recycling or harmless treatment.

This production line utilizes various advanced technological means, including physical sorting, chemical treatment, and biodegradation, to implement refined treatment of household waste. In the initial stage, the production line divides large and small pieces of material in the garbage through mechanical screening; Subsequently, utilizing magnetic separation technology to recover iron materials from garbage; Wind separation technology can separate lightweight waste such as plastic and paper.

In addition, the household waste sorting production line also uses biotechnology, such as composting fermentation, to convert organic waste into valuable fertilizer resources. For garbage that cannot be directly recycled, the production line will also take harmless treatment measures, such as incineration for power generation or safe landfill, to minimize the impact on the environment.

The efficient operation of the household waste sorting production line can not only significantly reduce the total amount of garbage and alleviate environmental pressure, but also achieve a dual improvement in economic and environmental benefits through resource recovery and reuse. More importantly, this approach helps to enhance public environmental awareness and promote sustainable social development.

In summary, the household waste sorting production line, as an important link between environmental protection and resource regeneration, is changing our living environment with its efficient and environmentally friendly advantages. With the advancement of technology and the continuous improvement of environmental awareness, the production line for sorting household waste will play a more important role in the future, creating a greener and better urban life for us.

The household waste sorting production line is a highly integrated processing system, with the core goal of effectively classifying mixed household waste for subsequent recycling and harmless treatment. This system utilizes modern high-tech methods to deeply process garbage, covering multiple stages such as crushing, identification, and sorting, with a particular emphasis on the accuracy of garbage classification.

Its working principle is based on the deep integration of object recognition technology and mechanical sorting technology. Through sensors and image recognition technology, devices can quickly and accurately identify various items in garbage, and guide them to different processing channels based on preset classification rules. In the sorting channel, various technical means such as airflow sorting, vibration screening, magnetic sorting, and optical sorting are used to finely separate and treat garbage. After multiple rounds of sorting and treatment, garbage can be effectively classified and utilized as resources.

This type of production line has the characteristics of energy conservation, environmental protection, and high recycling rate, which helps to improve the environmental conditions of waste disposal sites. It can adapt to the changes in garbage treatment needs of towns of different scales, while avoiding a series of problems caused by centralized garbage treatment during long-distance transportation. In addition, it has advanced bag breaking devices, crushing devices, air separation devices, and screening devices, with comprehensive functions, good sorting effects, high automation level, and relatively low processing costs.

However, there are also certain limitations to household waste sorting and processing equipment, such as high equipment procurement costs, high operating costs, and the need for professional technical teams to maintain due to its high complexity, which undoubtedly increases operating costs. In addition, the variety of garbage types can sometimes affect the sorting efficiency of equipment.

In summary, the domestic waste sorting production line has played a crucial role in the field of waste treatment, but there are also some areas that need improvement. With the continuous innovation and improvement of technology, we look forward to gradually solving these problems, making the domestic waste sorting production line more mature and efficient.
