Treating device for waste slag containing mercury

Abstract

The present invention is mercury containing waste slag treating device, and especially one mercury recovering apparatus for mercury containing waste slag. The present invention features that the mercury recovering apparatus consists of air exhaust tower, blower, secondary active carbon adsorber, primary active carbon adsorber, cooling water pipe, mercury collecting chamber, condenser, mercury removing heating furnace, feeding barrel, no-mercury slag collecting barrel, etc., which are connected with pipeline to constitute one reliable effective sealed treating system. The present invention has no secondary environment pollution and can extract metal mercury from waste slag while treating the waste slag to exhaust standard.

Description

Technical field: [0001] The invention relates to a waste treatment device in the environmental protection industry, more specifically to a device for recovering heavy metal mercury in discarded mercury-containing waste residue. Background technique: [0002] Like the production process of many fluorescent lamp factories, a large number of broken tubes and waste tubes that cannot meet the requirements of use will inevitably be produced, but they cannot be returned to the furnace for reuse, because these glasses already contain mercury added during the production process. It cannot be discarded casually, so it has to be crushed into mercury-containing waste residues and stored. Over time, it has piled up to a considerable size and cannot be disposed of. The government's environmental protection department is also strictly regulated. This is still the case in other factories, but other companies that use mercury as raw materials and auxiliary materials and the mercury-containin...

Problems solved by technology

[0002] Like the production process of many fluorescent lamp factories, a large number of broken tubes and waste tubes that cannot meet the requirements of use will inevitably be produced, but they cannot be returned to the furnace for reuse, because these glasses already contain mercury added during the production process. It cannot be discarded casually, so it has to be crushed into mercury-containing waste residues and stored. Over time, it has piled up to a considerable size and cannot be disposed of. The government's environmental protection department is also strictly regulated. This is still the case in other factories, but other companies that use mercury as raw materials and auxiliary materials and the mercury-containing wastes discarded in daily production are causing more and more serious harm to environmental protection. The existing technical information has not been found yet. There are relatively mature technologies for the treatment of such mercury-containing waste residues. Therefore, it is necessary to have a new treatment method and treatment device to separate the heavy metal mercury mixed in the waste residues without increasing new environmental pollution. Make the treated mercury-containing waste residue meet the discharge standard, and can be used for brick making, landfill, etc.
