Integrated plasma heat treatment method for ship solid waste

Abstract

The invention discloses an integrated plasma heat treatment method for ship solid waste, and relates to the field of waste treatment. The integrated plasma heat treatment method for the ship solid waste comprises the following steps that the ship solid waste is divided into kitchen waste and other waste, the other waste is divided into incinerable waste and non-incinerable waste, the non-incinerable waste is crushed to be the waste with an average particle size of 20-30 millimetres, compacting and packaging are conducted, the incinerable waste is crushed to be the waste with average particle size of 5 millimetres or below, plasma heat treatment is carried out to obtain tail gas and residual ash, the tail gas is discharged, and the residual ash is compacted and packaged; and the kitchen waste is treated by using a kitchen waste treatment device. By means of the integrated plasma heat treatment method for the ship solid waste, efficient volume reduction and up-to-standard discharge of the ship solid waste can be achieved, and the comprehensive anti-pollution capacity of a water surface ship is improved.

Description

Technical field[0001]This application relates to the field of waste treatment, and specifically to an integrated plasma heat treatment method for ship solid waste.Background technique[0002]The solid waste from surface ships mainly includes food waste, plastic waste, metal, glass, ceramics, paper products, wood products, textiles, etc. For different types of solid waste, surface ships are usually equipped with various anti-pollution treatment equipment such as kitchen waste treatment devices, solid waste compactors, plastic waste treatment machines, incinerators, etc. Due to the wide variety of waste treatment equipment and cumbersome operations , Which brings additional burden to the crew’s daily use and maintenance; at the same time, due to the large difference in the characteristics of the solid waste components of the ship, the comprehensive treatment effect of the equipment is not ideal, and it takes up more overall resources, which is not conducive to the improvement of the ove...

Problems solved by technology

For different types of solid waste, surface ships are usually equipped with various anti-pollution treatment equipment such as kitchen waste treatment devices, solid waste compactors, plastic waste treatment machines, incinerators, etc. Due to the variety of waste treatment equipment and cumbersome operation , bringing additional burdens to the crew’s daily use and maintenance; at the same time, due to the large differences in the characteristics of the ship’s solid waste components, the comprehensive treatment effect of the equipment is not ideal, and it takes up more overall resources, which is not conducive to the improvement of the overall efficiency of the ship. And although conventional marine incinerators have been used to reduce the volume of solid waste, due to the need for oxygen combustion, the equipment is large in size and the tail gas discharged after incineration contains high levels of harmful gas pollutants, such as carbon monoxide (CO ), nitrogen oxides (NOx), sulfur oxides (SOx), dioxins, incomplete combustion organic matter and other harmful components
