Description
Technical field
The utility model belongs to low temperature process and separates air oxygen unit field, relates in particular to molecular sieve adsorber cleaning system.
Background technology
Molecular sieve adsorber cleaning system, as the key equipment of oxygen unit, is being undertaken the moisture purifying in raw air, and the effect of the impurity such as carbon dioxide and hydrocarbon is aluminium oxide and two kinds of adsorbents of molecular sieve wherein and play adsorbing.The supporting molecular sieve adsorber of current domestic large air separation plant adopts horizontal type level bed adsorber mostly; After the nineties in last century, liquefied air group of France releases its patented technology product vertical radial stream molecular sieve adsorber, it has structure and the power savings advantages such as distribution of air flow is favourable, floor space is little, good stability, strong adaptability, and the outer manufacturer of Present Domestic all promotes this advanced technology in active research.But the vertical radial of method liquid air stream molecular sieve adsorber, after nearly 10 years of operation, manifests a defect gradually, the replacing that is exactly aluminium oxide to this absorber and adsorbent of molecular sieve is very difficult.Horizontal molecular sieve adsorber is because floor space is larger, highly low, and adsorbent filling manhole size is larger, and personnel can pass in and out freely, manually can load easily and remove adsorbent of molecular sieve.As shown in Figure 1, the design feature of vertical radial stream molecular sieve adsorber is that floor space is little, and between 20～30 meters, air intlet 2 is in absorber bottom highly greatly, and air outlet slit 5 is at absorber top; As shown in Figure 2, totally 6 of internal layer adsorbent filler 3(at absorber top around air outlet slit 5 cross-distribution) and totally 6 of outer adsorbent filler 4(), these 12 filling circular holes are cross-distribution, size less (at present generally at DN200～DN300), and personnel cannot enter; Filling can take to topple over mode, but it is more difficult to remove replacing.Once and adsorbent reaches service life or run into the faults such as molecular sieve water inlet, just need to change it.Because vertical radial stream molecular sieve adsorber technology is more advanced, the time that puts goods on the market is not long, at present, also there is no a kind of replacing method of simple general-purpose at home and abroad in this territory.The mode that Present Domestic generally adopts be with vavuum pump by adsorbent from the sucking-off of absorber filler, the adsorbent that vavuum pump is extracted out is piled up at the scene and need to be occupied larger area, also easily pollutes surrounding environment; Under the limited situation of working site area, need frequent start-stop pump have bad luck adsorbent, cause the activity duration to extend; In addition, vacuum pump need increase expense, area occupied, and the service life of adsorbent be 5 years, utilize under normal circumstances vavuum pump to change adsorbent 5 years and just use once, cause idleness of equipment waste and easy aged deterioration.
Utility model content
For overcoming the defect of prior art, the utility model provides a kind of more changing device of vertical radial stream molecular sieve absorber absorbent, changes difficult problem for solving vertical radial stream molecular sieve absorber absorbent.
Solve the problems of the technologies described above, the utility model provides a kind of more changing device of vertical radial stream molecular sieve absorber absorbent, special suction car, suction jockey, molecular sieve adsorber are linked in sequence, suction jockey one end probes into the adsorbent filler of molecular sieve adsorber, and the other end is connected with the import that carries pump of special suction car.
Suction jockey described in the utility model is the hard pipelines of two ends with elbow, and wherein upper end elbow can rotate freely.
An also corrugated stainless steel tubing of suction jockey described in the utility model, its two ends can bend to elbow by demand.
The technology that the utility model is changed vertical radial stream adsorbent of molecular sieve is exactly on the basis of existing technology, according to on-the-spot general condition, the special suction car of special type of utilization suction coal ash of power plant etc. extracts adsorbent of molecular sieve, the adsorbent of extraction is stored in vehicle, then transfers to storage place and stack.
For the utility model is utilized effectively, adopt aspirator to connect vertical radial stream molecular sieve adsorber and special suction car, described aspirator comprises a suction channel contour with vertical molecular sieve adsorber, described aspirator can be the hard pipelines of two ends with elbow, also can adopt corrugated stainless steel tubing.Above-mentioned device for cleaning pipeline is crossed to fixture to be separately fixed on the fixtures such as the fence of molecular sieve adsorber body upper and lower, one termination flexible pipe of described pipeline is probeed into absorber filler for aspirating adsorbent of molecular sieve, and the other end is direct or utilize the flexible pipe of Len req to connect the import of pump on suction car by special joint.Because aluminium oxide and two kinds of adsorbents of molecular sieve are distributed in respectively in different interlayers, need extract in each filling hole from different perspectives, therefore the movable elbow of described pipeline upper end is from all angles connecting hose for convenient.Also can use corrugated stainless steel tubing, its bending two ends is connected with the pump of flexible pipe and suction car.
Change difficult method and apparatus and have the following advantages for solving vertical radial stream molecular sieve absorber absorbent above:
1. applicable to different Site for Unit environment, be especially applicable to the less situation of Site for Unit area;
2. simple and fast, saving fund, saves time;
3. when increasing work efficiency, also met overhaul of the equipments demand it is pressed for time;
4. clean environment firendly, is difficult for polluting working site environment.
