High Temperature Pyrolysis And Gasification Waste Incinerator System - Pretreatment Introduction

1.Types of waste that can be processed by the High Temperature Pyrolysis And GasificationWaste Incinerator System

High-temperature pyrolysis gasification treatment equipment is mainly used for the harmless disposal of municipal waste generated in daily life. HYHH's small and medium-sized High Temperature Pyrolysis And Gasification Waste Incinerator System has a processing capacity of 3-200t/d and is suitable for the on-site treatment of municipal solid waste in remote areas with high transportation costs. Affected by the living habits, garbage collection and transportation methods of various countries/regions, there are great differences in the composition and proportion of garbage.

Types of waste can be processed: rubber and plastic, paper, knitwear, plastic, etc.

Types of garbage cannot be processed: explosive items (such as firecrackers, pressure vessels), electrical equipment (such as televisions, refrigerators), iron blocks, stones, large and long pieces of garbage (such as quilts, hemp ropes), as well as hazardous waste, industrial waste, construction waste, etc.

In addition, it is recommended to recycle recyclable items such as cardboard boxes, plastic bottles, and cans, which are more environmentally friendly.

2.Necessity of pretreatment system

Currently, only some first-tier developed cities implement garbage sorting. After sorting, the combustible content of dry garbage is large and the moisture content is low, which is a conducive to incineration disposal. Other regions adopt a mixed collection mode to collect raw garbage, which has complex composition and different sizes. It is very easy to get tangled together, blocking the garbage feed port, and requires manual cleaning, which is very dangerous. In addition, untreated mixed garbage directly enters the High Temperature Pyrolysis Waste Incinerator, which is prone to problems such as partial burning and agglomeration, affecting the stability of slag discharge and furnace operation.

The pretreatment system can achieve homogenization of the waste entering the incinerator through crushing, screening and other processes, ensure the long-term stable operation of the main incinerator, relieve the purification pressure of the subsequent flue gas treatment system, and extend the service life of the system. The pretreatment is designed and configured according to the actual composition of the waste in each region, which is more flexible and has a wider range of applications.

3.Pretreatment system equipment composition

Common pre-treatment system equipment includes overhead cranes, crushers, screeners, magnetic separators, etc. Garbage storage pits are used to store solid waste and collect leachate. Overhead cranes are used to grab solid waste and feed it into the crusher and main incinerator. Crusher generally uses a double-roll crusher, which uses two sets of relatively rotating rollers to crush materials, and is suitable for the treatment of waste with complex texture. Magnetic separators are used to separate iron wires and iron sheets from waste. The function of the screener is to sort out sand and gravel from the waste.
