Magnetic field intensity of the flowing channels is relatively uniform, the flowing velocity and flow are high in matching degree, sterilization and polarization of flowing fluid are sufficient, sterilization efficiency is high when fluid flows through at a time, polarization effects on water molecules in the fluid are good, and further the dehydration rate of sludge is reduced greatly.
Description
Technical field
The present invention relates to field of sludge treatment, pretreated magnetic sterilizing polarizer before particularly relating to the press filtration of municipal sludge.
Background technology
Magnetic sterilizing polarizer is that a kind of pipeline flowed through at fluid arranges magnetic source, fluid is allowed to flow through in the magnetic field of some strength, after fluid flows through magnetic region, microorganism in fluid is killed, water molecules in fluid is polarized, micromolecular water is become by macromole water, micromolecular water has good permeability energy, therefore this technology is when being applied to the pre-process of Filter Press slip, significantly can promote the working efficiency of pressure filter, under same operating condition, the water ratio in filtration filter cake can be made to decline 15 ~ 20%, even if the municipal sludge of extremely sad filter, this sludge slurry is by after magnetic polarization Sterilizers, enter pressure filter again, the water ratio of sludge filter cake also can decline 8 ~ 12%, about 62% can be dropped to from the water content of conventional press filtration 72%, effect is fairly obvious.But this magnetic sterilizing polarizer also also exists disposable overcurrent sterilization and insufficient situation that polarizes, if the sterilization effect had, fluid must be allowed to be repeatedly cycled through in polarizer, just can reach desirable effect through repeatedly overcurrent, cause the complexity of sterilising plant like this and then add cost, sterilizing and the present situation undesirable to water molecules polarization effect.This liquid iterative cycles polarization sterilizer of flowing through that requires, desirable sterilization effect just can be reached, cause the application of this product to bring inconvenience, pipe arrangement complexity, operational efficiency is low, when being especially applied in the dehydration pre-process of municipal sludge, more trouble, needs the outer Zeng Jia qian return pipe line of E, transfer storage tank, the equipment such as pressure feed pump, increase cost.
The first reason of above-mentioned deficiency is caused to be in the flow channels of polarization Sterilizers, caused by magneticstrength is uneven.As Fig. 1, a regional magnetic field intensity near magnetic source side is just strong, and the b regional magnetic field intensity from magnetic source distance is just weak.Wherein part fluid is when sterilizing polarizer, and the regional magnetic field flowed through is very weak, and the degree of strength of magnetic region is uneven, makes the fluid flowed through polarize uneven, result also in sterilization insufficient, the result that sterilising effect is bad.
Cause second reason that the polarization effect that flows through polarizer fluid is bad, it is too fast to be that fluid flows through the speed of magnetized area, and when especially fluid flows through low magnetic region, the flow velocity of fluid is fast, can cause fluid and magnetic region few for duration of contact, the result of magnetic efficiency difference.Also demonstrate this point in an experiment, with diameter 100mm latus rectum, the magnetic flux of magnetic source is the magnetic polarization Sterilizers of 1900GS is example, be matched in the pressure filter of 400 square metres, the dehydration pre-process of the settled sludge of filter sewage treatment plant, in the sludge slurry filling phase 10 minutes early stages of pressure filter, be 50m by the flow of polarizer
3/ h is 2.8 meter per seconds by the flow velocity of the mud of polarizer, and the sludge slurry sampling flowed through is observed, and sterilization rate, about 30%, under equal conditions the reduced velocity flow to 0.8 of fluid meter per second, can reach about 60% through observing sterilising effect.
Therefore, in the polarizer flow channels of above-mentioned prior art, magnetic intensity is uneven and do not mated by the rate of flow of fluid of polarizer, causes the major reason that the polarization sterilising effect of magnetic polarizer is bad, also becomes the main cause that dewatering rate is difficult to improve.Still there is the space that improvement promotes.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of flow channels magneticstrength relatively uniform, overcurrent flow velocity and flow matches degree high, the sterilization of overcurrent fluid and polarization are fully, once flow through germ-killing efficiency high, and then the magnetic polarization Sterilizers that can make dewatering rate significantly reduce good to the water molecules polarization effect in fluid.
For realizing the object of the invention, provide following technical scheme: a kind of sterilizing polarization device, it is characterized in that comprising housing, be arranged at the sterilizing polarisation unit that in housing, some groups are set up in parallel, described sterilizing polarisation unit comprises the flow channels in housing, the outer magnetic source of hull outside, housing, described each sterilizing polarisation unit flow channels entrance all connects an inlet duct, each sterilizing polarisation unit flow channels outlet all connects an outlet conduit, inlet duct is provided with mud inlet, outlet conduit is provided with mud mouth.
As preferably, described inlet duct and the equal upper and lower ends of outlet conduit through, and be provided with end cap.
As preferably, flow channels center is provided with the baffle of near for divided fluid stream guiding outer magnetic source side along flow path wall, baffle is provided with interior magnetic source or baffle is permanent magnet.
As preferably, the sealed body that baffle comprises both ends and forms along the interlude that flow path wall extends, the flow deflector that two pieces of being set to tilt clockwise in the end of corresponding flow channels import are symmetrical.
As preferably, outer magnetic source is electromagnetism magnetic source and/or permanent magnet.
As preferably, outer magnetic source list group or many group series connection compounds are arranged.
As preferably, sterilizing polarisation unit flow channels diameter is within 80mm.The outer magnetic source magnetic radiation distance controlling of sterilizing polarisation unit is between 20 ~ 30m.
The described flow velocity by sterilizing polarisation unit determines according to the index such as solid content, viscosity crossing fluid, and it is preferred for being generally arranged on 0.8 ~ 3 meter per second.
Described permanent magnet magnetic source can be comprise the various rare-earth permanent magnet magnetic sources such as iron oxygen antimony, Nd-Fe-B.
Beneficial effect of the present invention: the fluid passed through can be made to avoid the region of low magnetic flux amount, pass through in the region of high magnetic flux, obtain sufficient sterilization and polarization in the region of strong magnetic.During for dehydrating municipal sludge pre-process, because the sterilization of overcurrent fluid is abundant with polarization, the dehydration rate of mud can be made to be promoted to about 50% from 60%, generally can to promote dehydration rate about 10%.Owing to improve sterilizing and the polarization effect of sterilizing polarizer, for user saves the cost of postpositive disposal, there is good economic benefit.Make simple, Financial cost is not high, and the beneficial effect ratio produced with improvement, has fabulous cost performance, while not improving cost of manufacture, significantly can promote the action effect of magnetic sterilizing polarizer.
