Description
Technical field
The present invention relates to a kind of low dew point rotary wheel dehumidifying unit, be specially adapted to air humidity is had lithium battery production line, fluid injection glove box and the out of use dehumidifying of the return air space of strict demand.
Background technology
Violent chemical reaction (spontaneous combustion) can take place with other high-energy such as lithium, metal plate, highly active metal cause that thereby fire works the mischief in the aqueous vapor that the moisture in atmosphere reaches the certain upper limit air.Therefore the lithium battery manufacture process requirement uses relative humidity RH≤1% that its Production Regional was controlled and guaranteed to low dew point rotary dehumidifier, makes lithium battery industrially in batches to make.Yet, in processes such as lithium battery fluid injection, encapsulation, there is the inevitable volatilization of electrolyte and operating personnel and equipment produced heavy corrosion with the generation of water in air steam chemical reaction, influence the hydrofluoric acid of equipment performance.Answer this, relevant drying room technological requirement adopts brand-new wind to handle in actual production process.
The low dew point dehumidifier of general single-stage runner adopts full return air closed circulation; Dew point is unstable; Cause design redundant big; The occupation area of equipment coefficient is high, initial cost is high, the high stability of a system of operation energy consumption is difficult to satisfy lithium electrician industry production concerned process steps technological requirement, especially in the lithium battery that has pollution medium to produce is produced.Application number is the device that relates to a kind of continuous preparation low dew point low temperature drying air in 200810018933.8 the patent application; The regeneration wind of this device is directly got the outer high humidity environment air of machine; Because low dew point dehumidifier air-out dew point requires very high; Taking from the highly humid air of external environment possibly scurry in the dry air along with the rotation of runner, influences air-out humidity; Unit does not use the regenerated heat reuse yet, improves the energy consumption of equipment.Simultaneously, owing to adopt the sealing flow process, the etchant gas in the lithium battery manufacture process can't be removed, and in machine, circulates for a long time, and runner is produced corrosion, not only influences the stability of complete machine, and the life-span also shortens greatly.
Now low dew point dehumidifier majority on the market be the twin-stage runner, and the twin-stage rotary dehumidifier is owing to be provided with a regeneration airduct between two runners, can cause scurrying wind, leaking out than the regeneration airduct of length, and the stability of unit is had certain influence.While also will be installed the conciliation air-valve owing to front and back level rotary wheel regeneration air quantity is inconsistent on this regeneration airduct, has so just increased the debugging difficulty and the systematic uncertainty of unit.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing above-mentioned deficiency in the prior art, and the low dew point dehumidifying of a kind of brand-new wind unit is provided, and has reduced the consumption of unit energy, reduces equipment cost, has reduced the length of equipment.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: the low dew point dehumidifying of this brand-new wind unit; Comprise and just imitate leaf filter, one-level refrigerant surface cooler, one-level processing blower fan, desiccant wheel, secondary surface refrigerant cooler, regenerative heater, regeneration blower fan, three grades of refrigerant surface coolers; It is characterized in that also being provided with the two stage treatment blower fan, PLC controls system; New wind air inlet, just imitate leaf filter, one-level refrigerant surface cooler, one-level and handle blower fan UNICOM successively; The said desiccant wheel center of circle radially is provided with renewing zone, regeneration cooling zone, degree of depth dehumidifying district, preparatory dehumidifying district; One-level is handled blower fan, preparatory dehumidifying district, secondary surface refrigerant cooler, two stage treatment blower fan UNICOM successively; Two stage treatment blower fan and regeneration cooling zone, degree of depth dehumidifying district UNICOM; Degree of depth dehumidifying district and three grades of refrigerant surface coolers, processing air outlet UNICOM successively; Regeneration cooling zone, regenerative heater, regeneration blower fan, regeneration exhaust outlet be UNICOM successively, and PLC control system all is connected with one-level refrigerant surface cooler, one-level processing blower fan, two stage treatment blower fan, desiccant wheel, secondary surface refrigerant cooler, regenerative heater, regeneration blower fan, three grades of refrigerant surface coolers.
Desiccant wheel of the present invention adopts the single-stage runner, and the renewing zone of desiccant wheel, regeneration cooling zone, degree of depth dehumidifying district, preparatory dehumidifying district are four different sector regions.
The Plane Angle in renewing zone of the present invention, regeneration cooling zone, degree of depth dehumidifying district, preparatory dehumidifying district is followed successively by 60 °, 60 °, 120 °, 120 °.
Renewing zone according to the invention, regeneration cooling zone, degree of depth dehumidifying district, preparatory dehumidifying district are each other through fluosilicic rubber isolating seal.
PLC control according to the invention system is provided with regeneration temperature of outgoing air sensor, regeneration heating-up temperature sensor; Be installed in the outlet of regeneration blower fan, regenerative heater respectively; Temperature in regeneration air draft and the regenerative heating process is exceeded the scope of setting carry out the overtemperature switch protection; PLC control system handles blower fan, two stage treatment blower fan, regenerative heater, regeneration blower fan to one-level and carries out chain control; Handle in blower fan, two stage treatment blower fan, the regeneration blower fan any one when breaking down when one-level, cut off the electrical heating of regenerative heater automatically.
When unit of the present invention shuts down; PLC control system judges regeneration heating and regeneration temperature of outgoing air automatically, when regeneration heating and regeneration temperature of outgoing air all are lower than the safe temperature of setting, just cuts off regeneration blower fan, desiccant wheel motor, one-level and handles blower fan, the power supply of two stage treatment blower fan.
Unit adopts frame structure of aluminum alloy or square steel section material framework structure, utilizes the sealing of high pressure polyurethane foam board.Unit is provided with handles air inlet, processing air outlet, regeneration air outlet.Electric-control system is a PLC control system, through the touch-screen man-machine interaction.Adopt the PLC control system of research and development voluntarily, can gather, analyze and take corresponding action to all kinds of parameters of unit and service environment, make the control of unit flexible, easy to operate according to customer requirements.
Compared with prior art, the present invention has following advantage:
1, handle wind and all adopt outside new wind, being specially adapted to has lithium battery production line, fluid injection glove box and some of strict demand can not use the dehumidifying space of return air to air humidity.
2, regeneration wind is directly taken from processing wind, has avoided regeneration wind to take from the phenomenon of remote-effects processing air-out dew point when outdoor when this technical process will regenerate the heat recovery of cooling zone.
3, desiccant wheel adopts the single-stage rotor design, and the overall length of unit is reduced, and has reduced equipment cost with the space is installed.
When 4, the single-stage rotor design had been avoided the two stage dehumidify rotary wheel dehumidifying, the regeneration airduct that set up the centre was scurried wind, air leakage phenomena.
5, twice same runner of process of regeneration wind makes the dew point of handling air-out more stable, avoided the single-stage runner to hang down dew point dehumidifier unsettled situation of dew point when bad weather.
