Abstract

The invention discloses a high-temperature melting furnace which comprises a furnace body, a discharging pipeline and a plurality of electrodes. The furnace body is provided with a feeding port and a discharging port, the feeding port is located in the upper portion of the furnace body, the discharging port is located in the lower portion of the furnace body, and the electrodes are distributed in the furnace body at intervals and located in the area between the feeding port and the discharging port; one end of the discharging pipeline is communicated with the discharging opening, and the other end of the discharging pipeline is located outside the furnace body and extends to the area between the feeding opening and the electrode in the height direction of the furnace body. The multiple electrodes are arranged in the furnace body, the multiple electrodes are used for conducting high-temperature melting on waste incineration products to form high-temperature molten liquid and high-temperature molten smoke, and the high-temperature molten smoke is automatically cooled and condensed into liquid in the rising process in the furnace body; and the high-temperature melting liquid can be continuously and automatically discharged out of the furnace body through the discharging pipeline and is gradually cooled to become vitreous slag, so that the high-temperature melting furnace can be used for continuously and harmlessly recycling waste incineration products or waste pyrolysis products.

Description

technical field

[0001] The invention belongs to the technical field of solid waste reduction and harmless treatment, and in particular relates to a high-temperature melting furnace that can be used for recycling and processing waste incineration products. Background technique

[0002] my country's domestic waste has complex composition, high viscosity and high moisture content. At present, mixed collection and mixed treatment are usually adopted, specifically the method of waste incineration, which can play a great role in the reduction and recycling of waste. However, in the process of waste incineration, there will be a problem of "one in and four out", that is, waste incineration will decompose and produce products such as slag, fly ash, flue gas and leachate, of which about 3%- 5% of the fly ash, and if the fly ash as a hazardous waste cannot be treated and discharged directly, it will cause different degrees of harm to the atmosphere, soil and human body.
