Abstract
The utility model discloses an air filtering device which comprises a filter and is characterized in that the filter comprises a primary metal net plate type low-efficiency air filter, a secondary bag-type low-efficiency air filter, a tertiary bag-type medium-efficiency air filter and a quartus sub high-efficiency air filter which are sequentially arranged along an air inlet. Due to the adoption of the technical scheme, the air filtering device disclosed by the utility model has the beneficial effects that the cleaning times of a platinum net is reduced and the cleaning frequency of the platinum net is reduced to once per four months from the cleaning frequency of once per month, so that the impurity content in the air is further reduced; and the air filtering device has the advantages of high purification degree, advanced process, firm structure and the like.
Description
Technical field
The utility model relates to the synthetic ammonia field, particularly a kind of air filter.
Background technology
In the ammonia synthesis process, according to the oxidation section technological requirement, need the catalytic action with a certain proportion of ammonia, air gas mixture process platinum guaze, reaction produces nitric oxide gas.Air filter adopts the Nylon Bag form that air is filtered at present, and its shortcoming is: degree of purification is low, and the air after the filtration is impure more; When getting into follow up device equipment; Equipment is caused to a certain degree damage, and impurity gets into oxidation furnace can make catalyst poisoning, and it is frequent to clean platinum guaze; The platinum consumption is high, increases cost.
Summary of the invention
To the problems referred to above, the purpose of the utility model is to provide a kind of degree of purification height, technology air filter advanced, firm in structure.
For achieving the above object; The technical scheme that the utility model proposed is: a kind of air filter; Comprise filter, it is characterized in that: described filter comprises just imitating in air cleaner, three grades of pocket types along the board-like thick effect air cleaner of the one-level wire netting that air inlet sets gradually, secondary pocket type imitates air cleaner, level Four inferior high-efficient air filter.
Further, described air filter comprises that also pointer pressure reduction shows meter and access door.
Adopt technique scheme; The beneficial effect that the described air filter of the utility model is had is: the platinum guaze wash number reduces; Once be reduced to cleaning in 4 months once by cleaning in former every month; Further reduce airborne impurity content, and had advantages such as degree of purification height, technology be advanced, firm in structure.
Description of drawings
Fig. 1 is ammonia in the ammonia synthesis process, air mixed catalytic sketch map;
Fig. 2 is the basic sketch map of the described air filter of the utility model;
Fig. 3 is the described air filter side view of the utility model;
Wherein: 1. imitate in three grades of pocket types air cleaner, 2. the secondary pocket type just imitate air cleaner, 3. the board-like thick effect air cleaner of one-level wire netting, 4. the level Four inferior high-efficient air filter, 5. the gas outlet, 6. pointer pressure reduction shows meter, 7. access door, 8. polyphenyl sandwich color steel plate, 9. building enclosure, 10. air inlet.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model is further specified.
Shown in ammonia, air mixed catalytic sketch map in Fig. 1 ammonia synthesis process, air pumps in the blender through air blast after air filter filters; Ammonia gets in the ammonia surge tank simultaneously, and after the ammonia filter filters, also gets in the blender, and air and ammonia get into oxidation in the oxidation furnace after in blender, fully mixing, and through the catalytic action of platinum guaze, reaction produces nitric oxide gas.In this section operation, the air filter of prior art adopts the Nylon Bag form that air is filtered, and its shortcoming is: degree of purification is low; Air after the filtration is impure more, when getting into follow up device equipment, equipment is caused to a certain degree damage; Impurity gets into oxidation furnace can make catalyst poisoning; The cleaning platinum guaze is frequent, and the platinum consumption is high, increases cost.
Like Fig. 2, shown in Figure 3; A kind of air filter; Comprise through polyphenyl sandwich color steel plate 8 and surround the air filter that building enclosure 9 is formed; Be provided with air inlet 10 and gas outlet 5 in the air filter; And be provided with the board-like thick effect air cleaner of one-level wire netting 3, secondary pocket type to the gas outlet 5 successively by air inlet 10 and just imitate in air cleaner 2, three grades of pocket types and imitate air cleaner 1 and level Four inferior high-efficient air filter 4, also be provided with pointer pressure reduction in addition on the air filter and show meter 6 and access door 7.
During concrete the use, air filters through the level Four filter, and wherein: it is 70% that the secondary pocket type is just imitated air cleaner Dui ≧ 5um dust particle filter effect; Dui ≧ 1um dust particle filter effect is 95% to imitate air cleaner in three grades of pocket types; Level Four inferior high-efficient air filter Dui ≧ 0.5um dust particle is 99%.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
Claims (3)
