Description
Technical field
The utility model belongs to the converter gas process field, relates in particular to the parts in the flue gas analyzing apparatus of a kind of hot junction.
Background technology
Hot junction flue gas analyzing apparatus in the steel-making converter is one of visual plant of converter gas treatment system, is mainly used in the gas pretreatment system, and its quality directly has influence on the yield of the preparatory and coal gas of converter of gasometry.But in actual use, the hot junction flue gas analyzing apparatus often breaks down, and makes coal gas of converter not reclaimed normally, has caused great energy dissipation and financial loss.Through secular observation analysis, we find that the failure rate of the secondary filter in the flue gas analyzing apparatus of hot junction is the highest, because the significant deficiency that exists is gone up in its design, are easy to produce the phenomenon of gas leakage, thereby the works better of impact analysis instrument influences coal-gas recovering.
Strainer one in the flue gas analyzing apparatus of hot junction has four layers of filtration, as shown in Figure 1, be respectively process pipeline sampling by filtration device PRF, secondary filter MGF, the first filter-paper filter PF1 and the second filter-paper filter PF2, secondary filter MGF is the second layer wherein, its main effect is that the gas of elementary dedusting is further carried out dedusting, and certain shock absorption to be arranged, because the 3rd layer and the 4th layer of dedusting are smart dedusting, the dedusting material is a filter paper, and too fast gas flow rate can break through filter paper, simultaneously, not good as secondary strainer dust removing effects, can cause the too fast consumption of filter paper, the work-ing life of the brief first filter-paper filter PF1 and the second filter-paper filter PF2 is so secondary filter is topmost dedusting section and breeze way.
Our existing analyser secondary filter as shown in Figure 2, mainly by filtering net joint 1, seal washer 2, filter grid 3, filter cushioning material 4, fixed link 5, strainer tube body 6, strainer tube fastening screw 7 and form.Strainer tube body 6 adopts the plexi-glass tubular material, the centre is equipped with and is filtered cushioning material 4 is glass fibre, filter cushioning material 4 two ends adopt filtering net joint 1 to clamp and be equipped with two seal washers 2, the filter cushioning material that supports because of glass fibre 4 is softer easily to be dispelled compression, so support with stock support 8 all around; Strainer tube body 6 is fixed by three fixed links 5, and undertaken fastening by six fastening screws 7, more complicated is installed, need blowing out to change, influence rhythm of production, in case fastening screw 7 is subjected to force unbalance when fastening, can cause the breakage of the strainer tube body 6 or the seal washer 2 of pmma material, thereby cause gas leakage; Simultaneously, at the scene Working environment down the reason of vibrations the strainer connection section is produced leak, extraneous air is drawn into, thereby influence the variable of gasometry, influence recovery quality; Filter grid 3 is covered with dust all over owing to long dust-filtering is easy to cause on the grid, influences the sample gas circulation, brings certain influence to gas sampling.When analyser is worked, to carry out the purging of sampling conduit after every stove finishing blowing, the filtration cushioning material of easily glass fibre in the strainer tube body 6 being made during blow-back 4 blows off, influences the performance of strainer, cause the life-span of strainer to shorten greatly, economic benefit is poor.
The utility model content
Technical problem to be solved in the utility model has provided the secondary filter of a kind of steel-making converter hot junction flue gas analyzing apparatus, and strainer tube body step-by-step design in this secondary filter connects by gas thread, and easy installation and removal should not produce gas leakage.
The utility model is achieved in that the secondary filter of a kind of steel-making converter hot junction flue gas analyzing apparatus, comprise the filtering net joint, filter cushioning material and strainer tube body, filtering cushioning material is contained in the strainer tube body, described strainer tube body is made of two sections body canned paragraphs and one section body dismounting section, the two ends of body dismounting section link to each other with an end of body canned paragraph by gas thread respectively, the other end of body canned paragraph links to each other with the filtering net joint, is provided with web plate with holes in the filtering net joint.
Described web plate with holes and filtering net joint are integrally formed.
Described filtration cushioning material is made by the Stainless Steel Wire material.
Described strainer tube body is made by stainless material.
Strainer tube body in the utility model connects combination by gas thread, only needs common wrench just can remove and install very easily, and use is reliable, easy maintenance; Web plate with holes and filtering net joint are integrally formed, have improved the effect of sealing; By the filter cushioning material that the Stainless Steel Wire material is made, the structural strength height does not need to fix by stock support, and can not blown off in purging, has improved work-ing life; The utility model is fit to all gases sample devices such as CO, N2, O2 to be used, and for the more abominable place of sampling environment, can effectively reduce the failure rate in the use especially, guarantees the stability of equipment, has very optimistic application prospect.
