Multigun type pulsation backwash filter

Technical field

The utility model relates to filter, especially a kind of multigun type pulsation backwash filter.

Background technology

In decarbonization process, the impurity of carrying secretly due to long-term running and unstripped gas, cause the amine liquid of some device excessively dirty, impurity is many, and solia particle is many, makes it to bubble, be with liquid etc., therefore must adopt the constant filtration of part amine liquid, reduce solvent loss, change operating conditions, also bring benefit to steady production simultaneously.Material enters the backwash filter body by inlet, and due to intelligent (PLC, DCS) design, system can identify the Impurity deposition degree automatically, gives blowoff valve signal automatic pollution discharge.

Backwash filter of the prior art adopts single backwash filter to carry out filtration operation, usually according to different application scenarios, selects small-sized, medium-sized, large-scale single backwash filter.If in the time of need to being used in non-standard backwash filter operation, also need to redesign filter, use trouble, cost is high.

The utility model content

The applicant uses dumb, high in cost of production shortcoming for the backwash filter that adopts independent (non-standard) structure in above-mentioned existing production technology, a kind of multigun type rational in infrastructure pulsation backwash filter is provided, thereby multi-joint dress having unit structure design, flexible and convenient to use, reduce costs.

The technical scheme that the utility model adopts is as follows:

A kind of multigun type pulsation backwash filter, comprise the filter that a plurality of spaced and parallel are arranged, the cartridge filter top of each filter is connected with the fluid pipeline by the first branch line respectively, described parallel with fluid pipeline desalted water pipeline and the nitrogen pipeline of being provided with, described desalted water pipeline and nitrogen pipeline also are communicated with the first branch line respectively; Be connected with the deslagging pipeline with the feed liquor pipeline respectively by the second branch line bottom each cartridge filter.

As further improvement in the technical proposal:

Also comprise the skid pedestal, described multigun type pulsation backwash filter is installed on the skid pedestal;

Be provided with valve switch on the first branch line on each cartridge filter and the second branch line;

Each cartridge filter top is equipped with filter cover by sealing device, and described cartridge filter top is provided with floral disc, has a plurality of grooves that filter core is installed on described floral disc.

The beneficial effects of the utility model are as follows:

The utility model adopts multi-joint dress filtration system, can carry out simultaneously a plurality of sample filterings, only needs a vacuum source just can complete all operations were, saves a large amount of time, and is convenient and swift.There is an independent switch each filter unit, can operate separately, can adjust usage quantity according to the actual treatment amount, and is flexible.

The utility model total system adopts the skid structure, convenient installation, dismounting and mobile, and the built-in PLC on the spot of skid switch board, convenient in time operation, and desired signal can be sent into DCS system remote centralized Control.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As Fig. 1, Fig. 2 and shown in Figure 3, shown in, the multigun type pulsation backwash filter of the present embodiment, comprise the filter that a plurality of spaced and parallel are arranged, cartridge filter 5 tops of each filter are connected with fluid pipeline 8 by the first branch line 3 respectively, parallel with fluid pipeline 8 desalted water pipeline 1 and the nitrogen pipeline 2 of being provided with, desalted water pipeline 1 and nitrogen pipeline 2 also are communicated with the first branch line 3 respectively; Are connected with the deslagging pipeline with feed liquor pipeline 9 respectively by the second branch line 12 and are connected in each cartridge filter 5 bottoms.Also comprise skid pedestal 7, multigun type pulsation backwash filter is installed on skid pedestal 7, namely adopts the skid structure, can install easily, dismantles and move, and uses flexibility good.

Be provided with valve switch on the first branch line 3 on each cartridge filter 5 and the second branch line 12.Can control respectively the operation of single filter, flexible and convenient to use.

Each cartridge filter 5 tops are equipped with filter cover 4 by sealing device, and cartridge filter 5 tops are provided with floral disc 10, have a plurality of grooves that filter core 11 is installed on floral disc 10.When long-term use needs more renew cartridge 11, only need open filter cover 4, take out floral disc 10, namely all filter cores 11 take out in the lump, take off filter core 11 and clean, new filter core 11 is once inserted in 10 recessings of floral disc, then connect floral disc 10 and together pack into and get final product in cartridge filter 5, shortened the replacing time, increased work efficiency.

See Fig. 1, an end of feed liquor pipeline 9 is inlet N1, and an end of fluid pipeline 8 is liquid outlet N2, desalted water pipeline 1 one ends are desalted water entrance N3, one end of nitrogen pipeline 2 is nitrogen inlet N4, and the other end of nitrogen pipeline 2 is exhaust outlet N5, and an end of deslagging pipeline 6 is slag-drip opening N6.

In actual use procedure, its operation principle is as follows:

See Fig. 4, first-selected according to use occasion, select the number of filters of required use.Control by each valve switch and use single filter, still use simultaneously a plurality of filters.

The first step: exhaust feed liquor

Automatically open air bleeding valve 02, liquid feed valve 1.01 ~ 5.01, intake valve 1.04 ~ 5.04, material enters cartridge filter 5 from inlet N1, and the interior gas of cartridge filter 5 is discharged from exhaust outlet N5 simultaneously, through Timer Controlling T1 time late gate autoshutdown.

Second step: normal filtration

Automatically open liquid feed valve 1.01 ~ 5.01, liquid valve 1.02 ~ 5.02, material from inlet N1 in cartridge filter 5, flow out from liquid outlet N2 by filter core 11, impurity screening forms filter cake and is attached on filter core 11 surfaces, through Timer Controlling T2 time and pressure difference signal PDT01 co-controlling valve autoshutdown (being as the criterion to arrive first).

The 3rd step: air water blowback

Enter the backwash state since No. 1 unit, automatically open nitrogen inlet valve 01, advance to clean water valve 1.03, intake valve 1.04, residual cake valve 1.05, the filter cake that will adhere to by the nitrogen G﹠W blows off to the cylindrical shell low head of cartridge filter 5, N6 discharges residue by slag-drip opening, realize the backwash of No. 1 unit, when No. 1 unit backwash finishes, through Timer Controlling T3 time late gate autoshutdown, begin again the first step " exhaust feed liquor " step, through Timer Controlling T4 time late gate autoshutdown, enter second step " normal filtration " step.

This moment, No. 2 unit began to enter the backwash filter as No. 1 unit, carried out successively this process with lower unit, thereby realized the backwash of each unit, and when last unit backwash end, system comes back to full filtration condition.

Because every filter works alone separately, so concerning whole system, the process of filtration is continuous.

The utility model adopts blocking, modularized design, Automatic Control, and the skid structure also can guarantee the various features of continuous operation etc., in the decarbonization process of cover more than being widely used in system, mainly be arranged on the other filter station of poor amine section, effect is remarkable, has obviously improved amine liquid quality.

Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
