Abstract
An apparatus 1 for disposal of wastes comprises a measuring hopper 2 for measuring a charging amount of a waste to be disposed such as domestic wastes, industrial wastes or the like or a charging amount of a solid fuel such as coke, coal or the like, a charging hopper 3 for charging the waste and the solid fuel respectively measured with the measuring hopper 2, a melting furnace 4 for melting the waste charged from the charging hopper 3 at a high temperature to conduct detoxification thereof, and a charging damper 5 arranged between the charging hopper 3 and the melting furnace 4 and having a multistage sluice valve system 9 capable of charging the waste and the solid fuel charged in the charging hopper 3 into the melting furnace 4 without outflowing of a furnace gas to exterior.
Claims13
An apparatus for disposal of wastes, the apparatus comprising:
- a measuring hopper configured for separately measuring each of a charging amount of a waste and a charging amount of a solid fuel,
- a charging hopper for charging separately measured amounts of each of waste and solid fuel, respectively, measured by the measuring hopper,
- a melting furnace for melting the waste charged from the charging hopper at a temperature sufficient for detoxifying melted waste,
- a charging damper arranged between the charging hopper and the melting furnace and having a multistage sluice valve system for charging waste and solid fuel charged in the charging hopper into the melting furnace without emission of toxic furnace gas outside the furnace, and
- a control device connected to the measuring hopper and the melting furnace and for adjusting the charging amount of solid fuel to the minimum amount required constantly to keep combustibility of solid fuel and waste in the melting furnace.
A process for disposal of wastes by melting in a melting furnace operating at a temperature sufficient for detoxifying melted waste, comprising
- calculating with a control device, a charging amount of waste and a charging amount of solid fuel to be charged into the furnace when a solid fuel previously charged in the melting furnace has been completely burned in the furnace,
- measuring charging amounts of the waste and solid fuel based on the calculated charging amounts, the charging amount of the solid fuel being the minimum amount required to maintain combustibility of the solid fuel and waste in the melting furnace, and
- charging each of the measured waste charging amount and solid fuel charging amount into the melting furnace.
