Abstract
The utility model discloses an ammonia process desulphurization unit absorbs scale deposit of section solution and clears away structure, it includes ammonia process desulphurization unit's desulfurizing tower, overhaul groove and pit, be connected with the absorption cycle pump on the desulfurizing tower, be connected with the delivery pipe of taking the valve between desulfurizing tower and maintenance groove, be equipped with the recovery tube of connecting the pit on overhauing the groove, it is connected with the arc division board to connect the recovery tube region at the maintenance inslot, the both sides of arc division board and the interior wall connection that examines and repair the groove, the lower extreme is connected with the bobbin base that overhauls the groove, be equipped with the pit pump of connecting the desulfurizing tower cylinder body on the pit. The utility model discloses desulfurizing tower absorption cycle pump outlet pipe line and nozzle jam speed have been slowed down to the suction of scale deposit granule greatly by reducible absorption cycle pump water inlet department, and the scale deposit cycle is from extending to more than 3 months less than one month.
Description
Technical field
This utility model patent relates to a kind of ammonia desulfuration equipment absorber portion solution removal of deposit structure, belongs to ammonia process of desulfurization equipment technical field.
Background technology
The ammonia process of desulfurization is a kind of efficient, the wet desulphurization mode of low power consuming, use widely, ammonia desulfuration equipment is in running, due to the enrichment of metal ion in solution in absorber portion, in the case of pH value is higher, easily produce and generate trickle fouling granule, during long-play, fouling granule can gradually enter at absorbent recirculation pump, deposition in outlet conduit and shower nozzle, even block, cause circulating absorption solution flow reduction, and then cause solution pH value to rise, fouling increases the weight of, form vicious cycle, eventually result in absorber portion circulation solution flow relatively design load to decline to a great extent, absorbability is substantially reduced, cause neat stress SO2Content overproof, is forced reduce boiler load or use the low-sulfur coal of higher price, can only stop tower and process, bring environmental protection and dual-pressure economically time more serious.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can significantly slow down desulfurizing tower absorbent recirculation pump outlet line and spray nozzle clogging speed, it is ensured that desulfurizer can run steadily in the long term.Ammonia desulfuration equipment absorber portion solution removal of deposit structure, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: ammonia desulfuration equipment absorber portion solution removal of deposit structure, it includes the desulfurizing tower of ammonia desulfuration equipment, maintenance groove and melt pit, desulfurizing tower connects and has absorbent recirculation pump, it is connected between absorption cycle pump inlet with maintenance groove and has the delivery pipe of band valve, maintenance groove is provided with the recovery tube connecting melt pit, melt pit is provided with the sump pump connecting desulfurizing tower, in maintenance groove, connect back to the connection of closed tube region have arc demarcation strip, the both sides of arc demarcation strip are connected with the inwall of maintenance groove, and lower end is connected at the bottom of the cylinder of maintenance groove.
Aforesaid ammonia desulfuration equipment absorber portion solution removal of deposit structure is, arc demarcation stripA diameter of 500-600mm , high 400-500mm 。
nullCompared with the prior art，The problem that this utility model easily blocks absorbent recirculation pump and pipeline thereof for the fouling proposed in background technology，Effectively make use of the maintenance groove in ammonia desulfuration equipment and melt pit，It has additional the newly-increased delivery pipe of band valve between desulfurizing tower and maintenance groove，In maintenance groove, connect back to the connection of closed tube region have arc demarcation strip，The both sides of arc demarcation strip are connected with the inwall of maintenance groove，Lower end is connected at the bottom of the cylinder of maintenance groove，So when detecting that in desulfurizing tower, in circulating liquid, foulant is more，Turn on maintenance groove and this scale removal pipeline of melt pit，The liquid more containing foulant is introduced maintenance groove，By more than 24 hours precipitations，In utilizing maintenance groove, precipitate is intercepted by newly-increased arc demarcation strip，Clear liquid after sedimentation is progressively recycled to absorber portion by melt pit，Thus the suction to fouling granule of the absorbent recirculation pump water inlet can be reduced，Significantly slow down desulfurizing tower absorbent recirculation pump outlet line and spray nozzle clogging speed，The fouling cycle extends to more than 3 months from less than one month，When fouling has increased the weight of，By short-term correction steam coal sulfur content，Absorbent recirculation pump flow can be made to recover；And it is deposited in the regular labor cleaning of the deposit of oil, sweat and dirt on the skin in maintenance groove.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
nullEmbodiment 1，As shown in Figure 1，Desulfurizing tower 1 connects and has absorbent recirculation pump 4，Maintenance groove 2 is provided with the recovery tube 6 connecting melt pit 3，Melt pit 3 is provided with the sump pump 8 connecting desulfurizing tower 1，For solving absorbent recirculation pump 4 fouling and clogging problem，A newly-increased delivery pipe 5 connecting absorbent recirculation pump 4 and maintenance groove 2，Newly-increased delivery pipe 5 is provided with valve，Newly-increased delivery pipe 5 is connected to desulfurizing tower 1 and can discharge the position of fouling liquid，In maintenance groove 2, connect back to the connection of closed tube 6 region simultaneously have arc demarcation strip 7，A diameter of 500-600mm of arc demarcation strip 7，High 400-500mm，During connection, the both sides of arc demarcation strip 7 are connected with the inwall of maintenance groove 2，Lower end is connected at the bottom of the cylinder of maintenance groove 2，It is allowed to constitute a relatively independent region，And the water inlet of recovery tube 6 is positioned at the bottom in this region，Thus may utilize this arc demarcation strip and effectively intercept fouling precipitation，Liquid after utilizing recovery tube 6 will to intercept precipitate imports melt pit 3，The sump pump 8 that recycling is connected between melt pit 3 and desulfurizing tower 1，Just liquid after precipitation can be put into desulfurizing tower 1 again，Realize the outer circulation of slagging-off.
