Equipment for Effectively Recycling Exhaust Gas from Small-scale Waste Incinerators

Introduction

This leaflet introduces equipment for drying and reducing inorganic sludge (slurry). Slurry is dried and reduced using the hot exhaust gas generated when incinerating solid waste (paper, plastic and wood scraps) generated in factories together with liquid waste such as paint cleaner that is difficult to incinerate.

The following waste can be incinerated:

1) General waste      :  Paper, wood, leather, etc. 

2) Industrial waste : Polyester, polypropylene, natural rubber

3) Liquid waste : Waste oil, paint cleaner, chemical waste liquids, etc.

Effective Recycling

1) Drying and reduction of inorganic sludge (slurry)
2) Drying and reduction of waste-water treated sludge

Features

1) We can supply the most suitable model from our extensive range of incinerators 
   to suit the characteristics of the waste (e.g. combined combustion of solids 
   and liquids) and user preferences (e.g. labor-saving).

2) Exhaust gas from the incinerator rises to temperatures in excess of 800deg.C. As a result, organic matter is broken down by oxidization, eliminating any influence on the waste to be dried.

3) A rotary drier with stirrer vanes is used as the drier to ensure savings in space.

4) Auxiliary equipment such waste-water treatment facilities and waste-heat recovery equipment is being used effectively at many other installations.

Installation Example

1) Solid waste: 2100 kg/day

2) Liquid waste: 3700kg/clay

3) Effective recycling: Sludge reduction 4.8 ton/day (65% W.B.) -> 1.9 ton/day (10% W.B.)
