Abstract

A method of recovering the metallic element from the gaseous mixture containing the carbonyl is in the nickel carbonyl production. The nickel carbonyl in the discharge gas is decompounded into the nickel powder and the CO in the 200-400 DEG C, the CO and the discharge gas burn in the incinerator in the 600-1000 DEG C, and the CO react to the CO2. the invention can recover the metallic element efficiently and improve the utilization ratio of the material. Also it has decreased the pollution to the environment.

Description

A kind of method that from the mixed gas that contains carbonyl compound, reclaims metallic element
Technical field
A kind of method that reclaims metallic element from the mixed gas that contains carbonyl compound relates to the treatment of waste gas method in a kind of nickle carbonoxide production process, especially from the method for the recovery metallic element of the waste gas that contains micro-nickle carbonoxide.
Background technology
Nickle carbonoxide is a highly toxic substance, is heated and easily decomposes.In the production process of nickle carbonoxide, can produce the waste gas that some contain micro-nickle carbonoxide, this waste gas is based on carbon monoxide and nitrogen, and this gas must disinfection before exhaust.Method commonly used at present is that directly discharging or simple combustion are handled, and has caused environmental pollution, metallic element to run off and the UTILIZATION OF VESIDUAL HEAT IN deficiency.And waste gas is being passed into incinerator high-temp combustion sterilization back emptying, nickle carbonoxide does not wherein have efficient recovery, causes metal loss.
Summary of the invention
The objective of the invention is to overcome in the existing treatment process directly discharging or simple combustion processing and can cause environmental pollution, metallic element to run off and the insufficient shortcoming of UTILIZATION OF VESIDUAL HEAT IN, a kind of method that reclaims metallic element from the mixed gas that contains carbonyl compound that can effectively solve problem of environmental pollution, efficient recovery metallic element and utilize waste heat is provided.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method that from the mixed gas that contains carbonyl compound, reclaims metallic element, it is characterized in that its removal process is to contain micro-nickle carbonoxide waste gas under 200-400 ℃ of temperature, nickle carbonoxide is decomposed into nickel powder and carbon monoxide, nickel powder is subjected to gravity settling separated from the gas, decompose the carbon monoxide discharge and waste gas by bagroom recovery nickel powder wherein after, entering incinerator burns under 600-1000 ℃ of temperature, make CO (carbon monoxide converter) gas wherein generate carbon dioxide, high altitude discharge then.
A kind of method that from the mixed gas that contains carbonyl compound, reclaims metallic element, it is characterized in that decomposing the device that contains micro-nickle carbonoxide waste gas is the shaft furnace of chuck heating; Conical lower portion at shaft furnace has a nickel powder collection box.
A kind of method that reclaims metallic element from the mixed gas that contains carbonyl compound, it is characterized in that decomposing the device that contains micro-nickle carbonoxide waste gas is that the shaft furnace that a chuck heats is with electrically heated.
Method of the present invention is characterized in that it being to have fed the chuck that decomposes the device that contains micro-nickle carbonoxide waste gas with the high-temperature flue gas that incinerator comes out shaft furnace is heated.
Method of the present invention, the waste gas (it forms most of be nitrogen, CO (carbon monoxide converter) gas) that will contain micro-nickle carbonoxide, carry out thermolysis makes wherein nickle carbonoxide be decomposed into nickel powder to obtain reclaiming in decomposer the inside, nickle carbonoxide decomposes the gas and nitrogen, the CO (carbon monoxide converter) gas that discharge and enters the high-temperature incinerator burning disposal, make CO (carbon monoxide converter) gas wherein be oxidized to nontoxic carbon dioxide, the high-temperature flue gas that comes out from incinerator turns back to the chuck internal heating decomposer of decomposer, thereby reaches the utilization again of waste heat.Method of the present invention has reclaimed metallic element effectively, has improved utilization ratio of raw materials.To enter in the incinerator from the gas after decomposing, carry out degree of depth sterilization, reduced environmental pollution.
