Abstract

The invention discloses industrial spent selenium material recycling equipment. The industrial spent selenium material recycling equipment comprises a feeding device, an oxidizing furnace, a storage device and an air draft device which are connected in sequence; the feeding device and the oxidizing furnace are installed on a bottom frame; the feeding device is used for feeding spent selenium materials into the oxidizing furnace; the oxidizing furnace is used for oxidizing selenium in the selenium-deficient material to generate SeO2; the material storage device is used for collecting SeO2 powder discharged from the oxidizing furnace; and the air draft device is used for pumping out waste gas and the SeO2 powder in the oxidizing furnace and purifying the waste gas. The equipment disclosed bythe invention can convert selenium in the spent selenium material into SeO2 powder and then recycle the SeO2 powder, can obtain SeO2 with the purity of 80%, realizes recycling of selenium resources,solves the problem of environmental pollution caused by dumping of the selenium-deficient material, is high in automation degree, can realize automatic feeding and automatic discharging, reduces manual operation, improves production efficiency, can process a large amount of raw materials, causes less pollution, and is low in processing cost and good in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of recovery and utilization of industrial selenium-depleted materials, and in particular relates to equipment for the recovery and utilization of industrial selenium-deficient materials. Background technique [0002] Selenium (Se) is a kind of scattered non-metallic element, and it is also an essential trace element for humans and animals. Trace amounts of selenium can prevent cancer and protect the liver. At the same time, selenium has a wide range of uses and can be used in metallurgy, glass, ceramics, Electronics, solar energy, feed and many other fields, and with the development of the world economy and the emergence of new application fields, the downstream demand for selenium continues to grow. [0003] Industrial selenium-depleted materials refer to materials with selenium content less than 3% produced during the production of industrial selenium products. At present, there is no proper treatment met...
