Abstract
The utility model relates to an exhaust gas purifying device of a rotary kiln for rare earth metallurgy. The exhaust gas purifying device consists of a primary treatment chamber, a secondary treatment chamber and a settling chamber which are sequentially connected, wherein a gas inlet is arranged at the front end of the primary treatment chamber, and a gas outlet is arranged at the upper part of the settling chamber. A magnetic purifier is arranged in the front of the primary treatment chamber, and a water curtain is arranged at the back of the primary treatment chamber; and the top end of the inside of the secondary treatment chamber is connected with a gas baffle, and an impeller is arranged in the middle of the secondary treatment chamber. Dust particles can be effectively filtered out and recycled by the exhaust gas purifying device, the toxic part contained in gas can be effectively melted by a pool, and the treatment efficiency is high.
Description
Technical field
The utility model relates to field of metallurgical equipment, is specially a kind of rotary furnace waste gas purification apparatus for rare earth metallurgy.
Background technology
Along with the quantity that rare earth element is used is more and more, for the recycling of non-renewable valuable rare earth resources, just become a vital task of Rare Earth Production enterprise.The waste material first step that reclaims is to do pyrophorisity to burn, usually the equipment that adopts is rotary furnace, neodymium iron boron waste material obtains entering next process after powder after rotary furnace burns again, can produce a large amount of toxic gases in this process, directly discharging is to environment and harmful, the grinding impurity that is also adulterating useful in gas causes the waste of resource.Existing exhaust-gas treatment treating apparatus adopts the screen pack filtering gas usually, exists processing not thorough, the problems such as the bad processing of dust that filters out.
The utility model content
The technical problem that the utility model solves is to provide a kind of rotary furnace waste gas purification apparatus for rare earth metallurgy, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of rotary furnace waste gas purification apparatus for rare earth metallurgy is comprised of the primary treatment chamber, secondary treatment chamber and the expansion chamber that connect successively, and described primary treatment chamber front end is air inlet, and described expansion chamber top is the gas outlet.Described primary treatment chamber interior front end is provided with magnetic purifier, and inner rear end is provided with cascade; Described secondary treatment chamber interior top is connected with gas baffle, and the middle part is equipped with impeller.Described gas baffle is for being obliquely installed, and described secondary treatment indoor bottom is the pond, and described magnetic purifier is comprised of each magnetic board of of two ends, up and down.
Beneficial effect
The utility model is filtering dust particle and recovery effectively, can effectively melt toxic moiety contained in gas by the pond, and treatment effeciency is high.
