Design of household waste slag screening project

Design of household waste slag screening project

Domestic waste slag refers to the slag generated in the process of urban Incineration, which usually contains organic matter, inorganic matter, heavy metal and other substances, and is harmful to the environment and human health. Therefore, the screening and treatment of household waste slag is an important part of urban environmental protection work. This article will introduce the design and operational steps of a household waste slag screening project.

1、 Project Design

1.1 Project Background

The domestic waste slag is a kind of solid waste produced in the production process of urban Incineration plant, which contains a large number of harmful substances such as organic, inorganic and heavy metals. If left untreated, it can cause serious harm to the environment and human health. Therefore, designing a household waste slag screening project is of great significance for protecting the environment and people's health.

1.2 Project Objectives

The goal of this project is to design a set of household waste slag screening equipment that can effectively separate harmful substances from the slag and reduce the harm to the environment and human health.

1.3 Design requirements

(1) Efficiency: The equipment should have efficient screening ability, which can effectively separate harmful substances from the furnace slag.

(2) Stability: The equipment should have stable operating performance, be able to operate stably for a long time, and ensure the screening effect.

(3) Safety: The equipment should have good safety performance and ensure the safety of operators.

1.4 Design Plan

(1) Screening equipment: vibrating screen, cyclone separator, magnetic separator and other equipment are used for screening and separation of slag in this project.

(2) Operation process: Domestic waste slag enters the vibrating screen through a conveyor belt for preliminary screening, and slag particles with a diameter less than 10mm are screened out; Then enter the cyclone separator for further separation to separate slag particles with diameter less than 5mm; Finally, it enters the magnetic separator for the separation of magnetic substances.

(3) Equipment configuration: the project needs to be equipped with vibrating screen, cyclone separator, magnetic separator and other equipment, as well as conveyor belt, dust remover, electric control cabinet and other auxiliary equipment.

2、 Operating Steps

2.1 Equipment Installation

Determine the installation location of the equipment to ensure its stability and safety.

(2) Install the equipment according to the equipment installation drawings to ensure its correctness and stability.

2.2 Equipment debugging

(1) Perform electrical wiring on the equipment to ensure its normal operation.

(2) Start the equipment, debug various parameters of the equipment, and ensure the efficiency and stability of the equipment.

2.3 Equipment operation

(1) Transport household waste slag to a vibrating screen for preliminary screening.

(2) Deliver the preliminarily screened slag particles to the cyclone separator for further separation.

(3) Transport the separated slag particles to the magnetic separator for the separation of magnetic substances.

2.4 Equipment Maintenance

(1) Regularly maintain the equipment to ensure its normal operation.

(2) Clean and maintain the equipment to ensure its service life and operational efficiency.

3、 Summary

The design and operation of household waste slag screening projects are of great significance for urban environmental protection and people's health. In this project, vibrating screen, cyclone separator, magnetic separator and other equipment are used to screen and separate the slag. The operation process is simple and efficient, and can effectively separate the harmful substances in the slag. During equipment installation, debugging, operation, and maintenance, attention should be paid to the safety and stability of the equipment to ensure its normal operation and service life.
