A process for lowering the carbon content in ash includes introducing the ash having a carbon content of 1 to 20 wt-% into a reactor where the ash is burnt at a temperature between 700 and 1100° C. Fuel is also introduced into the reactor. During combustion, microwave radiation is fed into the reactor. At least part of the energy released during the combustion is recovered.

An environment-friendly corpse treatment apparatus comprises: a drying portion for removing moisture contained in a corpse; a pulverization portion for applying an impact to the moisture-removed corpse to pulverize the same into small pieces; and a foreign matter separation portion for separating a foreign matter contained in the pulverized corpse. The corpse loaded at the drying portion is dried in a vacuum state. The apparatus is environmentally friendly since a pollutant such as a toxic exhaust gas or dioxin is not generated, soil is not contaminated when a corpse is buried. A treated corpse is appropriate for natural burial or woodland burial since the treated corpse can be used as a nutrient. A corpse can be used as manure or feed if the corpse is animal waste.

A suction device has a suction pipe for aspirating fumes containing metal particles, in particular welding fumes, which aims to allow safe control of the fumes with a minimum of equipment expense and operational expense. For this purpose, an oxidation apparatus is provided according to the present invention. The particles flowing past the oxidation apparatus during operation are heated by way of a power supply and are thus oxidized.
摘要:
An air purification system includes a reverse flow heat exchanger, a combustion chamber and a means for heating particles configured to cause particles in air to combust in the chamber. The reverse flow heat exchanger transfers excess heat from the purified air to the incoming air to lower the amount of energy needed to combust the particles in the combustion chamber. The means for heating particles can comprise a flame or a microwave emitter. The reverse flow heat exchanger is spiral wound around the combustion chamber.

A high-frequency induction-heating device preferably comprises an introduction part which introduces a gas to be treated; a pyrolysis part which pyrolyzes the gas to be treated; an induction heating coil provided around the outer circumference of the pyrolysis part so as to surround and heat the pyrolysis part, and an exhaust part which exhausts the gas having been decomposed in the pyrolysis part; wherein the pyrolysis part comprises a cylindrical body both ends of which are sealed, slits which communicate the interior with the exterior of the cylindrical body provided on the outer surface of the cylindrical body, and a communication pores to be communicated with an introduction tube which introduces the gas to be treated into the interior of the cylindrical body.
摘要:
The invention discloses a microwave off-gas system in which microwave energy is used to treat gaseous waste. A treatment chamber is used to remediate off-gases from an emission source by passing the off-gases through a susceptor matrix, the matrix being exposed to microwave radiation. The microwave radiation and elevated temperatures within the combustion chamber provide for significant reductions in the qualitative and quantitative emissions of the gas waste stream.

Apparatus suitable for vitrifying nuclear waste comprises a tunable microwave cavity connected by a first wave guide to a source of microwave energy; cooling coils for cooling the exterior of the cavity; a hopper for loading particulate fusible material to the interior of the cavity; within the cavity a crucible made of melted and re-solidified fusible particulate material; an exit-chamber connected by a second waveguide to a second microwave source; and a pipe for supplying argon gas to the exit chamber so that a plasma torch can be generated. The separating of the crucible form the cavity walls by unmelted material gives significant advantages in case of cleaning and reduced energy consumption.
摘要:
A materials treatment system which initially separates liquid and solid components with a separator. The system can be advantageously utilized for household sewage handling, however various components have other applications. Once the separator separates the solids and liquids, a fire tube combusts the solids with microwaves. The liquids exiting the separator are treated in a liquid treatment system which includes additional particle filtration/separation, treatment of the liquids with an oxidant liquid, and an ultraviolet treatment. An advantageous microwave cavity assembly is also provided for dehydration/combustion of solids exiting the separator and/or for solids filtered from liquids in the liquid treatment system.
摘要:
A melting furnace that incorporates the autoclave theory and is equipped with a high-frequency (horizontal wave) device for incinerating material and for thermal decomposition and recrystallization of organic and inorganic hazardous compounds contained in it and to detoxify hazardous substances that have been recrystallized or thermally decomposed by using specific solvents. A method to accomplish the above is provided and hazardous gas that is generated during the incineration process at high temperature and under high pressure in the furnace is treated.
