Abstract
A waste gas purification device for a tombarthite smelting rotary furnace comprises a primary treating chamber, a secondary treating chamber and a settling chamber, which are sequentially connected, wherein the front end of the primary treating chamber is a gas inlet; the top of the settling chamber is a gas outlet; double magnetic grizzly screen dust removing plates are arranged at the front end in the primary treating chamber; a water screen is arranged at the rear end in the primary treating chamber; an alkali water tank is arranged at the lower part in the secondary treating chamber; a sealed gas guiding pipe is arranged between the primary treating chamber and the secondary treating chamber; a vent pipe immersed in the alkali water tank is connected with the lower end of the sealed gas guiding pipe; a vent through hole perpendicular to the extending direction of the vent pipe is formed in the vent pipe; a plate changing machine is connected with the double magnetic grizzly screen dust removing plates; a water inlet and a pollution discharge opening are formed in the secondary treating chamber. Compared with the prior art, the waste gas purification device can filter dust particles and recycle effectively, and melt poisonous parts contained by gas, and is high in treating efficiency.
Description
Technical field
The utility model relates to Rare Earth Production field, is specially a kind of rare-earth smelting rotary furnace waste gas purification apparatus.
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 reclaiming is to do pyrophorisity to burn, conventionally the equipment adopting is rotary furnace, neodymium iron boron waste material obtains entering next process after powder after rotary furnace burns again, in this process, can produce a large amount of toxic gases, directly discharge 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 screen pack filtering gas conventionally, exists processing not thorough, the problems such as the bad processing of dust filtering out.
Utility model content
The technical problem that the utility model solves is to provide a kind of rare-earth smelting rotary furnace waste gas purification apparatus, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of rare-earth smelting rotary furnace waste gas purification apparatus, formed by the primary treatment chamber connecting successively, secondary treatment chamber and expansion chamber, described primary treatment chamber front end is air inlet, described expansion chamber top is gas outlet, described primary treatment chamber interior front end is provided with two slot grid dedusting plates, and inner rear end is provided with cascade; The indoor bottom of described secondary treatment is potass pool, between described primary treatment chamber and secondary treatment chamber, be provided with sealing wireway, described sealing wireway lower end is connected with the breather pipe that immerses potass pool, and described breather pipe is provided with the ventilation through hole perpendicular with breather pipe bearing of trend.
Further, described pair of slot grid dedusting plate is connected with and changes plate device.
Further, described secondary treatment chamber is provided with water inlet and sewage draining exit.
Compared with prior art, the utility model is filtering dust particle recovery effectively, can effectively melt toxic moiety contained in gas by potass pool, and treatment effeciency is high.
