Abstract
The utility model provides a power distribution connection structure of a circulation slurry pump of a flue gas desulphurization system, which can ensure that when one power supply circuit is interrupted, not all circulation slurry pumps arranged on a glue gas desulfurizing tower can stop working. The flue gas desulphurization system comprises at least one flue gas desulfurizing tower; each flue gas desulfurizing tower is provided with at least two circulation slurry pumps; and the circulation slurry pumps arranged on the same flue gas desulfurizing tower are electrically connected with different power supply circuits respectively. In the power distribution connection structure of the circulation slurry pump of the flue gas desulphurization system, power is supplied to the circulation slurry pumps arranged on the same flue gas desulfurizing tower respectively by different power supply circuits so as to ensure that at least one circulation slurry pump of each flue gas desulfurizing tower runs when one power supply circuit is interrupted, and under that condition, only a boiler is needed to run with reducing load without halt, and a flue gas spray cooling scrubbing system is not needed to be started, thereby ensuring that internal structures of the flue gas desulfurizing tower can not be damaged.
Description
Technical field
The utility model relates to flue gas desulfurization technique field and distribution technique field, is specifically related to a kind of flue gas desulphurization system recycle slurry liquid pump distribution syndeton.
Background technology
Common flue gas desulphurization system is by two fume desulfurizing towers of a boiler configuration, does not have bypass between fume desulfurizing tower inlet and the outlet, and the number of the recycle slurry liquid pump of every fume desulfurizing tower configuration is determined by the desulfurizing tower material balance.In the present flue gas desulphurization system, all recycle slurry liquid pumps of a fume desulfurizing tower are powered by same current supply circuit.In the time of this current supply circuit maintenance, just need cut off the power supply, outage will cause all recycle slurry liquid pumps of this fume desulfurizing tower all can shut down because of outage.Simultaneously again because fume desulfurizing tower is not provided with bypass; high-temperature flue gas will enter in the fume desulfurizing tower; cause members such as the inner anticorrosive coat of fume desulfurizing tower, spraying layer, demister to damage; for preventing above-mentioned damage; just need to start flue gas mist cooling washing system; require the boiler main shut-down system simultaneously, and main shut-down system is with the tremendous loss that causes.
The utility model content
In view of this, in order to address the above problem, the utility model provides a kind of flue gas desulphurization system recycle slurry liquid pump distribution syndeton, can guarantee that the recycle slurry liquid pump of fume desulfurizing tower configuration can all not quit work when a current supply circuit outage.
The purpose of this utility model is achieved in that flue gas desulphurization system recycle slurry liquid pump distribution syndeton, described flue gas desulphurization system comprises at least 1 fume desulfurizing tower, each described fume desulfurizing tower disposes at least 2 recycle slurry liquid pumps, and the recycle slurry liquid pump of same fume desulfurizing tower configuration is electrically connected with different current supply circuits respectively.
Further, described flue gas desulphurization system comprises first fume desulfurizing tower and second fume desulfurizing tower, and each fume desulfurizing tower disposes N recycle slurry liquid pump, described N 〉=2, and described current supply circuit is made up of first current supply circuit and second current supply circuit; 1 recycle slurry liquid pump of described first fume desulfurizing tower configuration is electrically connected with first current supply circuit, and other N-1 recycle slurry liquid pump of described first fume desulfurizing tower configuration is electrically connected with second current supply circuit; 1 recycle slurry liquid pump of described second fume desulfurizing tower is electrically connected with second current supply circuit, and other N-1 recycle slurry liquid pump of described second fume desulfurizing tower configuration is electrically connected with first current supply circuit.
Flue gas desulphurization system recycle slurry liquid pump distribution syndeton of the present utility model; recycle slurry liquid pump to same fume desulfurizing tower configuration is powered by different current supply circuits respectively; guarantee when a current supply circuit outage; each fume desulfurizing tower has a recycle slurry liquid pump at least in running; only need the operation of boiler load down under this situation; and needn't shut down, also need not enable flue gas mist cooling washing system and just can guarantee that the fume desulfurizing tower internals can not damage.
Other advantages of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Description of drawings
In order to make the purpose of this utility model, technical scheme and advantage clearer, the utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 shows flue gas desulphurization system recycle slurry liquid pump distribution syndeton schematic diagram.
The specific embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
Referring to Fig. 1, the flue gas desulphurization system recycle slurry liquid pump distribution syndeton of present embodiment, two fume desulfurizing towers that comprise a boiler configuration, each fume desulfurizing tower disposes 4 recycle slurry liquid pumps, wherein the recycle slurry liquid pump 11 of first fume desulfurizing tower configuration is electrically connected with first current supply circuit 1, by 1 power supply of first current supply circuit, recycle slurry liquid pump 12,13,14 is connected with second current supply circuit electricity 2, by 2 power supplies of second current supply circuit; The recycle slurry liquid pump 21 of second fume desulfurizing tower configuration is electrically connected with second current supply circuit 2, and by 2 power supplies of second current supply circuit, recycle slurry liquid pump 22,23,24 is electrically connected with first current supply circuit 1, by 1 power supply of first current supply circuit.Like this, when one of them current supply circuit in first current supply circuit 1 or second current supply circuit 2 has a power failure owing to maintenance or other reason, can guarantee that the recycle slurry liquid pump of each fume desulfurizing tower configuration has at least one can turn round, avoid the fume desulfurizing tower internal damage.
The utility model is not limited to above-mentioned embodiment, as: also 2 in 4 recycle slurry liquid pumps of each fume desulfurizing tower configuration can be electrically connected with first current supply circuit 1, other 2 be electrically connected with second current supply circuit 2.The quantity of fume desulfurizing tower during greater than 4, respectively by different current supply circuits power supplies can realize of the present utility model goal of the invention as long as satisfy the recycle slurry liquid pump of same fume desulfurizing tower configuration greater than the recycle slurry liquid pump of 2 or the configuration of each fume desulfurizing tower.4 circulating pumps only are signals among the figure, are not limited to the situation of 4 recycle slurry liquid pumps in the practical application.
