Problems solved by technology

[0003] The existing arsenic-containing solid waste is treated by adding it to concrete for solidification treatment and then landfilling. Since concrete is still a porous substance, the problem of arsenic leaching may still occur when the concrete is aging or under the action of groundwater.

Abstract

The invention discloses a waste vitrification treatment system, which comprises a batching mechanism for preparing waste containing harmful substances and vitrification raw materials into granular materials together; the plasma gasification melting furnace is provided with an air inlet, a flue gas outlet and an inorganic matter discharge port, plasma beams sprayed from the air inlet heat the granular materials to be cracked and decomposed into inorganic matter melt and inorganic gas, the inorganic gas is discharged from the flue gas outlet, and the inorganic matter melt flows out from the inorganic matter discharge port; and the water quenching vitrification device is provided with a water spraying pipe and is used for cooling the inorganic substance melt, and the undecomposed harmful substances are combined with the glass.

Description

technical field [0001] The invention relates to a waste vitrification treatment system, in particular to a waste vitrification treatment system for harmless treatment of arsenic-containing solid waste. Background technique [0002] Arsenic is a highly toxic element, and a small amount of ingestion can cause death. Chronic arsenic poisoning can cause cancer and other diseases. On the other hand, arsenic is a relatively abundant element in nature, and it is one of the 20 most abundant elements in the earth's crust, and there are more than 200 arsenic-containing minerals. Large-scale arsenic pollution caused by natural and man-made causes has affected the health of hundreds of millions of people around the world. Arsenic pollution has become a worldwide environmental problem. With the deepening of people's awareness of the harmfulness of arsenic, the environmental protection department has become more and more strict on arsenic emissions. The U.S. Environmental Protection Age...
