Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model embodiment provides room, a kind of dehumidification type heat pump drying tunnel, comprising: tunnel 7, heat pump and ducting system.Heat pump is positioned at the one end in tunnel 7, and ducting system is connected with tunnel 7, composition air circulation loop, thus reaches the dehumidifying to article in tunnel 7, dry object.
Two ends, tunnel 7 are respectively equipped with tunnel end door 10 and machine hall 3, and side, tunnel 7 is provided with tunnel side door 11.Tunnel side door 11 is adjacent with machine hall 3.Be provided with materials vehicle 6 in tunnel 7, materials vehicle 6 can enter from tunnel side door 11 out from tunnel end door 10, facilitates the movement of material in tunnel 7.Further, tunnel 7 is also provided with moisture exhausting port, the moisture in tunnel 7 can be discharged.The control system (not shown in FIG.) controlling heat pump and ducting system is provided with in machine hall 3.
Ducting system comprises air supply duct 1, return air duct 5, breeze fan 2, return air fan 8 and equal wind apparatus 4.Breeze fan 2 is provided with in air supply duct 1.Have living space between tunnel end door 10 and tunnel 7, between return air duct 5 and tunnel 7, be provided with return air inlet 9, return air inlet 9 between tunnel end door 10 and tunnel 7 spatially.Return air inlet 9 is provided with return air fan 8, and return air fan 8 is positioned at the top of tunnel end door 10.Backwind tube 5 road is positioned at the top in tunnel 7, and return air duct 5 communicates with return air inlet 9.Air supply duct 1 is positioned at machine hall 3, and air supply duct 1 one end is connected with return air duct 5, and the other end is connected with equal wind apparatus 4, and equal wind apparatus 4 is arranged in machine hall 3.Therefore, air supply duct 1, tunnel 7, return air inlet 9 and return air duct 5 constitute an air circulation loop.Breeze fan 2, return air fan 8 add the flowing of air in ducting system, are provided with air quantity uniform distribution structure in the equal wind apparatus 4 of one end, tunnel 7, make the air entered in tunnel 7 be uniform up and down, thus it is evenly dry to realize material dolly about 6 energy.
Heat pump comprises compressor 16, condenser 12, fluid reservoir 19, device for drying and filtering 18, expansion valve 17, evaporimeter 14 and gas-liquid separator 15.Compressor 16 is connected with condenser 12, condenser 12 is connected with fluid reservoir 19, fluid reservoir 19 is connected with device for drying and filtering 18, device for drying and filtering 18 is connected with expansion valve 17, expansion valve 17 is connected with evaporimeter 14, evaporimeter 14 is connected with gas-liquid separator 15, and gas-liquid separator 15 is connected with compressor 16, forms whole heat pump.
The refrigerant gas of the low-temp low-pressure in compressor 16 pairs of heat pumps carries out compressing the refrigerant gas exporting HTHP.Condenser 12 is condensed into high pressure Normal Atmospheric Temperature Liquid the refrigerant gas of HTHP, and release heat.Expansion valve 17 becomes the refrigerant air-liquid two-phase mixture of low-temp low-pressure high pressure Normal Atmospheric Temperature Liquid, has the effect of the flow of throttling action and control cold-producing medium simultaneously.The throttling action of expansion valve 17: the liquid refrigerant of HTHP, after the throttle orifice throttling of expansion valve, becomes the vaporific hydraulic pressure cold-producing medium of low-temp low-pressure, for the evaporation of cold-producing medium creates conditions; Control the flow of cold-producing medium: the liquid refrigerant entering evaporimeter, after evaporator, cold-producing medium is evaporated to gaseous state by liquid state, absorbs heat, reduces temperature.Expansion valve 17 controls the flow of cold-producing medium, ensures that the outlet of evaporimeter 14 is entirely gaseous refrigerant, if flow is excessive, outlet, containing liquid refrigerant, may enter compressor and produce liquid hammer; If refrigerant flow is too small, evaporate in advance, cause refrigeration not enough.
Cold-producing medium evaporation endothermic in evaporimeter 14, becomes the refrigerant air-liquid two-phase mixture of low-temp low-pressure low-temperature low-pressure refrigerant gas and absorbs heat.When heat pump is in running, due to the change of operating mode or when adjusting heat pump, can, by back flow of refrigerant in fluid reservoir 19, with the internal circulating load of stable whole system inner refrigerant, it be made to be in normal operating condition.Gas-liquid separator 15 prevents liquid from entering compressor 16, causes the liquid hammer of compressor 16.Moisture in device for drying and filtering 18 sorption type heat pump system, stop moisture and impurity not by, prevent whole system pipeline generation ice stifled and dirty stifled.
Evaporimeter 14 and condenser 12 are arranged in air supply duct 1, and evaporimeter 14 is for dehumidifying to the damp-heat air of flowing in air supply duct 1, and condenser 12 carries out heat temperature raising to the dry air after dehumidifying.Be provided with captation 13 and drainage pipeline below evaporimeter 14, drainage pipeline reaches outside whole device, runs into for discharging damp-heat air the water that evaporimeter 14 becomes.
Principle of the present utility model: open breeze fan 2 and return air fan 8, the air dewetting of evaporimeter 14 pairs of air supply ducts 1, the air heat of condenser 12 pairs of air supply ducts 1; Heated dry air in air supply duct 1 is evenly delivered in tunnel 7 by equal wind apparatus 4, carries out drying to the material in material dolly 6 in tunnel 7; The damp-heat air produced is driven by return air fan 8 and enters return air duct 5 through return air inlet 9; Damp-heat air is sent in air supply duct 1 by breeze fan 2, dehumidifies through evaporimeter 14, and the dry air of generation is condensed after device 12 heat temperature raising and again enters tunnel 7 through equal wind apparatus 4, so circulates.In the process, damp-heat air is when evaporator 14, and the latent heat of the water vapour wherein in air is condensed into water by absorption, discharges through captation 13 and discharge pipe line; Refrigerant in heat pump enters condenser 12 after being compressed by compressor 16, transfers heat to condenser 12, makes condenser 12 add hot-air and forms hot blast, thus realize the recycling again of energy in the damp-heat air of dry run discharge.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
