A fully automatic high temperature plasma solid waste gasification melting furnace

Abstract

The invention discloses a full-automatic high-temperature plasma solid waste gasification and melting furnace which comprises a furnace body, a variable-frequency feeding system arranged on the top of the furnace body, a melting pool arranged at the bottom of the furnace body, two fused slurry liquid level detectors arranged at the bottom of the furnace body, a fused slurry outlet system and a gas outlet formed in one side of the upper end of the furnace body; a group of plasma generators are arranged at the upper part of the melting pool at the lower end of the furnace body; a group of swirl flow air nozzles are formed in the upper end of the plasma generators respectively and form a certain included angle with the center perpendicular line of the furnace body; and a thermocouple and an oxygen content detector are arranged on the outer sides of the furnace body respectively. According to the full-automatic high-temperature plasma solid waste gasification and melting furnace, various fuel oil and combustible gas can also be refined according to various solid wastes; and fused slurry is generated at the lower part of the melting furnace and forms a glass body to be capable of casting articles in different shapes after being drained without generating secondary pollution and having toxic substances including dioxin and heavy metal.

Description

technical field [0001] The invention belongs to solid waste treatment equipment, in particular to a full-automatic high-temperature plasma solid waste gasification melting furnace. Background technique [0002] With the rapid development of my country's economy, the output of solid waste is also showing an increasing trend. According to statistics, the output of industrial solid waste in my country was 950 million tons in 2002, 1.34 billion tons in 2005, and 1.76 billion tons in 2007. In 2010, the output of industrial solid waste in China exceeded 1.83 billion tons. . The harmfulness of solid waste pollution to the environment and human body cannot be ignored. It directly affects people's lives and seriously affects the environment and human health. Although the country's solid waste treatment capacity has been greatly improved compared to before, the current treatment of solid waste is still dominated by sanitary landfill, supplemented by composting and incineration.

Problems solved by technology

Although the country's solid waste treatment capacity has been greatly improved compared to before, the current treatment of solid waste is still dominated by sanitary landfill, supplemented by composting and incineration. Landfill and composting require a lot of land and space, and at the same time pollute the local environment and Groundwater; while incineration and co-combustion can achieve reduction and harmless treatment to a certain extent, it has been questioned by the public due to its potential secondary pollution (such as dioxins and heavy metals)
