Abstract

The invention discloses an industrial waste selenium material recovery and reuse equipment, which comprises a feeding device, an oxidation furnace, a material storage device and an air extraction device which are connected in sequence. The feeding device and the oxidation furnace are installed on a bottom frame, and the The feeding device is used for feeding the depleted selenium material into the oxidation furnace, and the oxidation furnace is used for oxidizing the selenium in the depleted selenium material to generate SeO 2 , the storage device is used to collect the SeO discharged from the oxidation furnace 2 powder, the air extraction device is used to remove the waste gas and SeO in the oxidation furnace 2 The powder is extracted and the exhaust gas is purified. The device of the invention can convert the selenium in the selenium-deficient material into SeO 2 The powder can be recycled to obtain SeO with a purity of up to 80% 2 , realizes the regeneration and utilization of selenium resources, and solves the problem of environmental pollution caused by the waste of selenium materials Large, small pollution, low treatment cost, good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of recycling and utilization of industrial spent selenium materials, in particular to an industrial spent selenium material recycling equipment. 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. A small amount of selenium can prevent cancer and protect the liver. 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-deficient materials refer to materials with a selenium content of less than 3% produced during the production of industrial selenium products. At present, there is no proper treatment method for industrial selenium-depleted materials, which are generally discarded directly as solid waste in the industry. However, seleni...
