Abstract
In order to solve problems existing in the prior art, the utility model discloses a magnetic filter for liquid ammonia. The magnetic filter comprises a main body, an inlet, an outlet, a filter screen and a magnetic adsorbent, wherein the inlet and the outlet are respectively located at the left and right of the main body; the filter screen and the magnetic adsorbent are located between the inlet and the outlet; the filter screen and the magnetic adsorbent are fixed through fixing piles; and the magnetic adsorbent is zigzag, so that the adsorption area can be greatly increased, and the adsorption capability can be improved. The magnetic filter is a filter device which is simple in structure, lower in cost and capable of filtering out iron-contained impurities in liquid ammonia.
Description
Technical field
The utility model relates to a kind of filter of industrial chemicals, particularly the magnetic filter that filters of a kind of ferrous contaminants of liquid towards ammonia.
Background technology
Liquefied ammonia is the primary raw material of producing nitric acid, the process of producing nitric acid is, liquefied ammonia generates gas ammonia through handling, be mixed into oxidation furnace with air in certain amount then and carry out oxidation, generate nitric acid through handling again, adopt platinum guaze as catalyst in the oxidizing process, owing to reasons such as production and pipeline conveyings, always have some ferrous contaminants to exist in the liquefied ammonia and since these ferrous contaminants with existing interception method can not filter to the greatest extent, so the ferrous contaminants in the liquefied ammonia always some is mixed in and enters oxidation furnace in the gas ammonia, these ferrous contaminants have entered oxidation furnace after stain platinum guaze, reduce oxygenation efficiency, the platinum consumption is increased, improved cost.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of magnetic filter of liquid ammonia, be a kind of simple in structure, lower-cost can be with the filter of the ferrous contaminants elimination in the liquefied ammonia.
For solving the problem that above-mentioned prior art exists, the technical scheme that the utility model is taked is: a kind of magnetic filter of liquid ammonia, it is characterized in that: comprise main body, lay respectively at import and the filter screen between outlet, import and the outlet and the magnetic adsorbent of main body left and right sides, described filter screen and magnetic adsorbent are fixed by spud pile, described magnetic adsorbent is zigzag, can increase adsorption area greatly, improve adsorption capacity.
Described filter screen is two-layer, can strengthen interdiction capability and the holding capacity of filter screen, improves the service life of filter screen.
Described import department has the fixed leg of spot distribution, is further used for fixedly filter screen and magnetic adsorbent, makes it more stable, can satisfy filtration and absorption under the high pressure conditions.
Describedly go out port radius less than inlet radius, can strengthen the time of staying of filtrate in main body, strengthen and filter and adsorption effect.
The utility model can be used on the existing liquefied ammonia pipeline, simple in structure, can effectively remove all kinds of impurity, especially significantly reduce the ferrous contaminants amount in the liquefied ammonia, improve the product oxygenation efficiency and reduce the platinum consumption, the utility model cost is lower, easy to use, long service life, result of use are remarkable, can chemical enterprise and and the fluid line that contains iron tramp be extensive use of, can raise the efficiency and save cost greatly.
