Abstract
The invention provides a magnetic filter which is used for adsorbing iron powder in gas ammonia by using a magnetic adsorbing column to reduce the iron powder content in the gas ammonia, purify the raw material and improve the oxidation rate of the ammonia. According to the technical scheme, the magnetic filter comprises a barrel 1, an inlet 2, an outlet 3, the magnetic adsorbing column 4, a flange plate 5, a bolt and a nut 6, wherein the top of the barrel 1 is provided with the inlet 2; the side face of the bottom end of the barrel 1 is provided with the outlet 3; the magnetic adsorbing column 4 is fixed to the flange plate 5; a connecting disc of the barrel 1 is fixed to the flange plate 5 by using the bolt and the nut 6.
Description
(1) technical field
The invention belongs to a kind of chemical filtration device, be specifically related to a kind of magnetic filter.
(2) background technology
At present in Chemical Manufacture, it is a technology that scientific and technological content is very high that raw material is processed, be related to the good and bad success or failure of product, especially in nitric acid production, ammonia is primary raw material, the oxygenation efficiency of ammonia is the important indicator of nitric acid production, the principal element that affects ammonia oxidation rate is the degree of purification of unstripped gas, especially the iron powder of carrying secretly in gas ammonia has the greatest impact, therefore in this field, should widely apply new technology, new method solves, and uses magnetic filter can reduce the content of iron powder in raw material, reach raising oxygenation efficiency, improve output, improve the quality of production
Magnetic filter can continuous operation, does not increase producing cost.
(3) summary of the invention
[problem that will solve]
The object of the invention is to overcome prior art deficiency, a kind of employing magnetic absorption post will be provided exactly, be adsorbed on the iron powder in gas ammonia, reduce the iron content in gas ammonia, reach the oxygenation efficiency of purification of raw materials, raising ammonia
[technical scheme]
A kind of magnetic filter, it comprises: cylindrical shell 1, and entrance 2, exports 3, magnetic absorption post 4, ring flange 5, bolt, nut 6, cylindrical shell 1 is offered entrance 2 at top, in side, bottom, set out mouth 3, magnetic absorption post 4 is fixed on ring flange 5, and the terminal pad of cylindrical shell 1 is fixed on ring flange 5, with bolt, nut 6, fixes.
[beneficial effect]
The present invention has following effect:
The present invention is by adopting magnetic absorption post to realize the absorption to iron powder in gas ammonia, and iron powder contained when gas ammonia enters magnet filter is held by magnetic absorption post, does not flow into next process.Thereby reach the function of purification.Can improve the utilization rate of ammonia, not increase again cost.
Production method of the present invention is simple, easy to operate, practical.
(4) accompanying drawing explanation
This figure is structural representation of the present invention: 1 cylindrical shell, 2 entrances, 3 outlets, 4 magnetic attached columns, 5 ring flanges, 6 bolts, nut.
(5) specific embodiment
When application, groundwork flow process is: the raw material ammonia that production nitric acid is used is before entering oxidation, carry out in advance magnetic filtration, magnetic filter is arranged on liquefied ammonia pipeline, entrance by magnetic filter enters in magnetic filter gas ammonia, gas ammonia contained trace iron pruinescence magnetic absorption post when by magnetic filter adsorbs, gas ammonia after purification is discharged by outlet, the operating pressure of magnetic filter (MPa) 1.2, pneumatic test pressure (MPa) 2.5, metered flow (m3/h)≤6.0, magnetic field intensity (GS) >=1200 ± 20, operating temperature normal temperature, the thickness of magnetic filter absorption iron powder can reach 10mm, magnetic filter was carried out to 1 cleaning in every two months.
Claims (4)
1. a magnetic filter, it comprises cylindrical shell (1), entrance (2) on cylindrical shell (1), outlet (3), magnetic absorption post (4), ring flange (5), bolt double-screw bolt (6), be characterised in that: the terminal pad of cylindrical shell (1) is fixed on the ring flange (5) that magnetic absorption post (4) are housed, with bolt, nut (6), fix, by entrance (2) outlet (3), carry out work.
