Abstract
The utility model provides an ammonia tail gas treatment device, and particularly provides a device for adsorbing and treating ammonia gas generated by ammonium paratungstate calcination in tungsten hydrometallurgy. The ammonia tail gas treatment device comprises a combustion chamber, a reaction cavity, an explosion-proof device and an absorption tower, the explosion-proof device is arranged at the lowest end, ammonia tail gas enters the treatment device through a gas inlet of the explosion-proof device, a heating element and a catalyst are sequentially arranged in the reaction cavity from bottom to top, the combustion chamber is arranged above the reaction chamber, and a gas outlet is formed in the top of the combustion chamber and connected with the absorption tower. The ammonia tail gas treatment device is simple in structure and convenient to use, and can appropriately eliminate pollution to environment from the ammonia gas through decomposition and combustion of the ammonia gas. The absorption tower at the tail end can further prevent unburned ammonia tail gas from escaping.
Description
Technical field
The utility model relates to tungsten field of smelting, is specially the ammonia that in a kind of tungsten hydrometallurgy, calcining produces to ammonium paratungstate and absorbs the equipment of processing.
Background technology
Along with the development of science, the various compounds of tungsten and the purposes of oxide are expanded greatly, also day by day various about the smelting process of tungsten.Hydrometallurgy is a kind of conventional process that tungsten is smelted, and in smelting production process, can produce ammonium paratungstate, produces tail gas during ammonium paratungstate calcining and decomposing, contains NH in tail gas
3, H
2o, O
2, N
2and dust, environment is had a serious impact.With regard to prior art, in the sector, do not have perfect ammonia vent gas treatment technology, some enterprises adopt spraying method to absorb and process, absorption liquid enters waste water, make ammonia nitrogen in industrial waste water content overproof, produced new secondary pollution, and the absorption of accomplishing ammonia tail gas that could not be perfect is processed.
Utility model content
The technical problem that the utility model solves is to provide a kind of ammonia tail gas treatment device, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Ammonia tail gas treatment device, comprise combustion chamber, reaction chamber, explosion-protection equipment and absorption tower, described explosion-protection equipment is arranged on least significant end, described ammonia tail gas enters treatment facility by the air inlet of explosion-protection equipment, in described reaction chamber, be provided with successively from top to bottom heater and catalyst, described ammonia tail gas heats by heater, by catalyst, decompose, described combustion chamber is arranged on the top of reaction chamber, after described ammonia tail gas decomposes in combustion chamber internal combustion, the top of described combustion chamber is provided with gas outlet, connect absorption tower, the tail gas of processing through combustion chambers burn passes into absorption tower and processes, prevented unburned tail gas effusion.
In the utility model, the side of described combustion chamber offers air inlet, necessary oxygen is provided to the burning of tail gas.
In the utility model, the outer wrap of described combustion chamber and reaction chamber has heat-insulation layer, is incubated to the decomposition reaction of tail gas and burning heat release, is convenient to recycling of heat, reduces energy consumption.
Beneficial effect: the utility model is simple in structure, easy to use, the pollution of the appropriate elimination ammonia of the decomposition by ammonia and Combustion Energy to environment, the absorption tower of end can also prevent that unburned ammonia from overflowing.
