Description

Dehumidification type frequency conversion heat pump drying machine
Technical field
The utility model relates to dehumidification type frequency conversion heat pump drying machine.
Background technology
Existing electrothermal drying technology mainly contains two kinds.First kind is that temperature elevation system and dehumidification system are independent mutually; Electrical heating is a cover system, and adding dehumidifier is another set of system, uses needs to satisfy.There is following defective in this technology: 1, dryer group itself does not possess dehumidification function, and the dehumidification rate of dehumidifier can and reduce along with the temperature rising, is higher than more than 35 ℃, does not dehumidify substantially.2, winter, power consumption was big, inefficiency.Temperature in the drying room is difficult to rise to serviceability temperature for the moment; 3, in heating process, the phenomenon that reddens of generating heat can appear in temperature elevation system (electric heating tube), there is potential safety hazard in dried material, and has a strong impact on the service life of compressor.4, temperature elevation system and dehumidification system are autonomous systems, and two device assembles are formed, and just existing in the control can not joint control, or can not in time find behind a certain unit failure.
Another kind is that the employing of heat pump drying unit is split type, does not have dehumidification function.Heat up by condenser and electrothermal tube, by high-power blower that hot and humid air discharge is outdoor under the condition of high temperature, thus reach the oven dry purpose.Also there is following defective in this technology: 1, unit itself does not possess dehumidification function, only depends on forced-ventilated under the humid tropical condition, and drying effect can't guarantee.2, outer machine frosting in winter, defrost still fail to solve, and weak effect reaches instructions for use reluctantly after increasing powerful auxiliary electrical heating; The operating cost height, not energy-conservation; 3, by force in the hydrofuge process, can form a large amount of heats and lose in vain, cause the wasting of resources.Simultaneously, drying room must be introduced new wind from the external world, has additionally introduced new moisture again, has prolonged drying time greatly.4, adopt the startup that temperature in the drying room or humidity controls unit and stopping, causing the main frame frequent start-stop, and do not reach desirable energy-saving effect.
The utility model content
The utility model provides dehumidification type frequency conversion heat pump drying machine in order to solve the above-mentioned deficiency of prior art.
Above-mentioned purpose of the present utility model realizes by following technical scheme: dehumidification type frequency conversion heat pump drying machine, comprise cabinet, be provided with frequency-changeable compressor, gas-liquid separator, electric cabinet, condenser, breeze fan, air outlet and electrocaloric effect in the described cabinet, it is characterized in that: described cabinet bottom is provided with evaporimeter, the auxilliary thermic devices of cold junction and air cleaner, described evaporimeter one side is provided with the air draft blower fan, and described cabinet bottom tank wall is provided with return air inlet, condensate pipe.
, by return air inlet the air in the drying room is extracted out in air-supply temperature increase interior between complete hermetically drying by air outlet, entered dehumidification system and dehumidify, with this intensification that constantly circulates, dehumidifying, reach dry requirement always and shut down.
The utlity model has following characteristics.
1, complete dehumidifying effect.
The unit temperature-rise period is a lasting cyclic process, and the warm and humid air in the drying room all must enter the evaporimeter dehumidifying.Guaranteed to enter air in the drying room and be fully the dry air after the dehumidifying, avoided in drying room, increasing humidity.Simultaneously, the high temperature humid air in the drying room has been guaranteed the suction temperature of unit and has not been influenced unit efficiency even system's operation behind the dehumidification system cool-down dehumidification.
2, intensification dehumidifying one.
Temperature elevation system and dehumidification system are combined into one effectively, have evaded the split type hidden danger of bringing.Two systems connect each other, merge mutually, and any unilaterally going wrong all can in time be found.Integrated control reaches perfect combination, realizes intensification removal moisture drying one fully.
3, high-efficiency electric-heating device technique.
The ventilation of electrocaloric effect is adopted and is enterprisingly gone out mode down, wind is introduced from the electrocaloric effect top by breeze fan, by the below of the electrocaloric effect that seals wind is discharged.The high speed hot blast can pass through electrothermal tube fully, the heating efficiency of electrothermal tube is improved, and rubescent phenomenon can not occur.Under having guaranteed the working environment in the electrocaloric effect, the service life that can improve electrothermal tube.
4, adopt the compressor variable frequency technology.
Adopt frequency-changeable compressor, after the temperature in the drying room reached set temperature value, the compressor starts converting operation had avoided main frame the phenomenon of frequent start-stop to occur.Thereby guarantee the temperature that drying room is interior with minimum input power, further guarantee the energy-saving efficiency of equipment.
5, air cleaning treatment technology.
Air cleaner is installed in the unit air return system return air air in the drying room is carried out sending into drying room or discharge again after the purified treatment, effectively ensured the cleaning of material in the drying room.Improved the quality of material widely, hazardous material (fluids) has further been eradicated potential safety hazard.
6, heating efficiency continuously.
Unit was opened the wind hole in the dividing plate between condenser and evaporimeter in the removal moisture drying process.Avoid the air-supply blast too high and condensation temperature is too high and influence equipment operation even can not work, can realize continuing circulation heating, stable operation.
7, constant temperature cold junction thermal source, no defrost.
In the winter time between algid stage; when heating up first in the drying room; the required heat of the not enough evaporimeter of heat the air of in drying room, drawing back; then carry out heat supplement by the auxilliary thermoelectric heating tube of cold junction; guarantee that the frosting phenomenon does not appear in unit operation; guarantee that unit is in normal operating conditions always, improve serviceability.
8, utilize the heat exchange of air source.
Between non-algid stage in winter, during through the required heat of the not enough evaporimeter of warm and humid airborne heat in after the heat regenerator cooling, replenish by introducing the new wind-heat amount in outside, too much low temperature dry air is discharged by breeze fan, realize air source heat exchange, reduce power consumption, improve the efficiency of unit, improve energy-saving benefit.
The utility model advantage compared with prior art is: effectively solved heat pump dryer energy-conservation, problem such as cost is high, can not at high temperature dehumidify inadequately; Avoided not rise because of defrost the problem of temperature fully; In comprehensively energy-conservation, realize zero-emission fully, natural environment is not had any pollution destroy.
