Description
Technical field
The present invention relates to a kind of by the device of recovery centrifugal after brine concentration crystallization.
Background technology
Sodium-chlor is widely used in food, chemical industry, biology, medicine and other fields, these fields all can produce thousands of ton discarded salt solution every day, if directly outer row, not only waste resource, the more important thing is the restraining effect because sodium-chlor produces nature microorganism, thus serious negative effect is produced to ecotope.Scientific research confirms: when the sodium chloride concentration in water body reaches 1%, will suppress the Growth and reproduction of most of microbe; And when the sodium chloride concentration in water body reaches 4%, the microorganism of most degraded COD, BOD all can not survive.
Therefore, reclaiming the sodium-chlor in Waste brine and not only have important economic implications, also have important Significance for Environment, is the important means realizing energy-saving and emission-reduction, preserve the ecological environment.Because the solubleness temperature influence of sodium-chlor is very little, when 100 DEG C, every 100 grams of water can dissolve 39.8 grams of sodium-chlor, also 35.7 grams can also be dissolved when 0 DEG C, therefore, the mode of condensing crystal generally can only be adopted to reclaim, but lack the complexes of recovery centrifugal after brine concentration crystallization in prior art, the breakthrough of complexes needs to overcome that concentrated heat exchange tank inwall effective heat exchange area is little, efficiency is low, be difficult to be separated after concentrated heat exchange tank inwall crystallization attachment and remove, crystallizer such as easily to block at many technical bottlenecks.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, a kind of perfect in shape and function is provided, the concentrated heat exchange tank coefficient of heat transfer is high, velocity of evaporation is fast, be convenient to be separated after concentrated heat exchange tank inwall crystallization attachment, though be also easy to after crystallizer blocking to solve by the complexes of recovery centrifugal after brine concentration crystallization.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of by the device of recovery centrifugal after brine concentration crystallization, comprise concentrated heat exchange tank and crystallizer, it is characterized in that: concentrated heat exchange tank be inner core and urceolus composition the long tubular construction of jacketed type and lateral arrangement, rotating shaft is horizontally through from inner core, anchoring fiber brush bundle in rotating shaft; Concentrated heat exchange tank inner core to be connected through airduct the concentrated heat exchange tank inner core formation evaporation circuit that to be linked back again after cyclonic separator with vacuum fan; The used heat pond heat exchanging pipe of concentrated heat exchange tank chuck and return water pipe, boiler, water circulating pump and water inlet pipe form heating cycle loop; Concentrated heat exchange tank chuck connects the water hammer vibrator of crankshaft-link rod and piston composition; Concentrated heat exchange tank left end is higher than right-hand member, and its left end is provided with solution inlet pipe to be concentrated, and right-hand member connects crystallizer through chute; Crystallizer is cone bottom structure, and the cone end connects spiral centrifuge and concentrated heat exchange tank inner core through mortar pump, and spiral centrifuge is provided with centrifugate temporary tank and crystal groove.
Described concentrated heat exchange tank inner core be provided with adjustable with fiber brush bundle distance except brilliant cross bar.
Described crystallizer is provided with vibrator.
Described centrifugate temporary tank connects solution inlet pipe to be concentrated through water pump.
Described crystallization tank body is communicated with at the bottom of crystallizer with anti-blocking pump through pipeline.
The design is the waste water and the draining of boiler used heat that utilize boiler wet method dedusting, is directly contacted, realize less energy-consumption brine concentration by septate heat transfer in conjunction with air with salt solution, and then realizes sodium-chlor recovery and energy-saving and emission-reduction.
Device is made up of two portions, heat exchange concentrates and Crystallization Separation, heat-exchanger rig is formed primarily of the fiber brush bundle of reasonable Arrangement in inner core, urceolus, rotating shaft and rotating shaft, inner core and urceolus form chuck, slightly inclination angle is installed, left end is slightly high, and fiber brush bundle is arranged close to cylinder body bottom, and the chuck that inner core and urceolus are formed is water-cycle heating.
During device running, solution to be concentrated is introduced by inlet pipe, start evaporation circuit and and heating cycle loop, solution to be concentrated flows out from left to right, air is pumped by blower fan through inner core from right to left, salt solution is evaporated, solution is caught backflow by cyclonic separator by unevaporated salt solution, solution is rotarily driven by fiber brush bundle and forms reverse-flow direct contact heat transfer with airflow and rapid water evaporates, simultaneously from the hot water of boiler also by partition and solution high efficient heat exchanging, dual function makes solution rapid evaporation to be concentrated.
Evaporation concentration makes partial oxidation sodium crystallization on concentrated heat exchange tank inwall and fiber brush bundle, when fiber brush bundle is by the attachment of comparatively polycrystal, can operate except brilliant cross bar completes cleaning operation close to or far away from fiber brush Shu Peihe axis of rotation; When concentrated heat exchange tank inwall has more crystallization, the water hammer vibrator of crankshaft-link rod and piston composition can be started, make dilation in tank body elastic range by high-low pressure Aquapulse, concentrated heat exchange tank inwall crystallization be peeled off and comes off.
Solution after heating is concentrated enters crystallizer by chute, when not starting crystallization, complete iterative cycles by mortar pump to concentrate, start mortar pump when crystallization needs and extract magma to spiral centrifuge, whizzer small end exports crystal in the temporary transfer of crystal groove, clear liquor flows to centrifugate temporary tank, and the liquid in temporary tank sends heat exchange concentration tank concentrated crystallization further back to by water pump.
When crystallizer bottom deposit crystal too much causes blocking, anti-blocking pump can be opened and stir loose mouth of pipe place crystal, restart mortar pump and complete crystal conveying separation; When the crystallization of crystallizer tank skin is more, the vibrator that can start many reasonable set layout makes crystal peel off output.
Compared with prior art, beneficial effect of the present invention is also:
Overcome the concentrated heat exchange tank coefficient of heat transfer low, concentrated slow-footed defect, air source evaporation is all efficient countercurrent flow in conjunction with the heating of partition water, also the ingenious fiber brush bundle that make use of rotates the stirring of solution and gets rid of to barrel process, fiber brush bundle attaching liq and air-flow heat exchange are evaporated, and solution and barrel has very large effective heat exchange mass transfer area and the heat exchange efficiency of solution inside is also very high, thus heat exchange flow, water evaporation quantity are all very big.
Operation except crystalline style can close to away from fiber brush bundle, coordinate axis of rotation can the convenient crystal cleaning operation completed on fiber brush bundle.
Water hammer vibrator uses high-low pressure Aquapulse to make dilation in tank body elastic range that inwall crystallization is peeled off to come off, especially efficiently, ingenious and thorough, to equipment without any damage.
Pump recoil is used to dredge the crystal blocking of crystallizer, simple and reliable, ingenious.
Utilize boiler used heat to carry out evaporation concentration, realize Waste Heat Reuse and energy-saving and emission-reduction.
The present invention conceives uniqueness, ingenious, practical, provide a kind of perfect in shape and function by the device of recovery centrifugal after brine concentration crystallization, have a extensive future.
