The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of heat pump removal moisture drying system, referring to Fig. 1, comprise heat pump assembly and drying box 11, heat pump assembly comprises evaporimeter 13 and condenser, condenser comprises indoor condenser 7 and outdoor condenser 6, and being connected between evaporimeter and indoor condenser is provided with chemical seasoning device 12 in air channel 14.Also comprise indoor fan 8 and outdoor fan 5.
Referring to Fig. 2, chemical seasoning device 12 comprises drier, is arranged on and connects in air channel 14, connects air channel 14 and is provided with the access port 15 for access drier.Access port 15 places are provided with wind blocking door 17, and wind blocking door 17 moves by the slide rail 16 that is arranged on access port 15 places, opens or closes access port 15.Between wind blocking door 17 and chemical seasoning device 12 casings, there is seal gasket.It between chemical seasoning device 12 and drying box 11, is embedded connection.Drier is selected silica gel.
Heat pump assembly by compressor 1, indoor condenser 7, outdoor condenser 6, expansion valve 3, evaporimeter 13, reservoir 4, stop valve 2, refrigeration valve 10, heat the closed system that valve 9 and connecting pipe form, be wherein filled with cold-producing medium.Heat pump assembly is for heat cycles air and remove the part moisture of circulated air, circulated air is at the interior circulating-heating dried material of drying box 11 and take away the moisture in dried material, chemical seasoning device 12 is connected with drying box 11 by bolt, the humidity of circulated air further can be reduced to carrying out fast of being conducive to be dried.The circular flow in system of heat pump assembly work schedule cryogen.Air in drying box 11 circulates under the effect of indoor fan, cold-producing medium generation exchange heat during through indoor condenser 7 and in heat pump assembly, temperature raises, dried material moisture is taken away while flowing through dried material, then at evaporimeter 13 places again with cold-producing medium generation exchange heat, temperature reduces, discharges of condensing of steam wherein, humidity reduction.When chemical seasoning device 12 in the circulated air connection air channel of flowing through between indoor condenser and evaporimeter after humidity reduces, the agent that is dried absorbs moisture, and humidity further reduces, and then starts next round circulation through indoor condenser.Drier in chemical seasoning device 12 can be opened access port 15 and carries out access by being slidably mounted on wind blocking door 17 on slide rail 16.The Main Function of outdoor condenser 6 is for fear of excess Temperature in drying box, in the course of work, can heat valve 9 and refrigeration valve 10 makes cold-producing medium through indoor condenser 7 or outdoor condenser 6 by switching.Drier in chemical seasoning device is selected silica gel.
Using method of the present utility model is as follows:
1, material to be dried is put into drying box 11, drier packs in chemical seasoning device 12, starts compressor 1, and system is introduced into intensification link, be that indoor condenser 7 and evaporimeter 13 heat respectively and freeze, indoor fan 8 rotates the dry air making in drying box 11 and forms closed circuit.When dry air passes through evaporimeter 13 under the effect of indoor fan 8, steam part is wherein met condensation knot, dry air water capacity declines, then dry air is through chemical seasoning device, the airborne moisture of drier absorption dehydration, dry air water capacity is further declined, and then the drying medium dried material of flowing through again after indoor condenser 7 heat temperature raisings is again dried.
2, detect in real time the situation of change of dry air relative humidity by being placed on hygrometer after the forward and backward and chemical seasoning device of evaporimeter, when dry air relative humidity variations significantly time when (being less than 5%) after chemical seasoning device, illustrate that drier interior moisture content reaches certain limit, now should change drier.When drier is changed, only need to open the drier that wind blocking door 17 takes out chemical seasoning device and be reentered into not water suction from access port 15, not affect the normal operation of system.
3, dry run may need repeatedly to perform step 2, until be dried.
4, after material to be dried has been dried, in drying box 11, leave part of waste heat, now the drier after moisture absorption can be put into drying box 11 and carry out desiccant dehumidification, make drier continue next time to use, to reach the object economizing on resources.
