Description
Technical field
The utility model relates to a kind of gas-gas heat pump drier.
Background technology
The high speed process of modernized society, it is fast-developing to promote industry, and promotes improving constantly of people's living standard.Dry technology has also obtained vigorous growth and significant progress, drying machine applies to each field of society more and more widely, people will strengthen gradually for the dependence of drying process, and drying sizable a kind of unit operations that is industrial consumption energy, account for 8%～12% more than of the total power consumption of industry in developed country, and this numeral is in continuous increase.Use mineral matter fuel to carry out drying process simultaneously and produce a large amount of carbon dioxide as thermal source; the waste gas that these drying machines emitted is also carried some dust secretly; atmospheric environment is had harmful effect, and this is a challenge greatly for causing that day by day " environmental protection " paid close attention in the whole world.The development of society be unable to do without dry technology, the working mechanism of correctly understanding drying and drying equipment helps successfully finishing dry run, go further to carry out the research and development of dry technology but still need constantly drop into the man power and material so that it is when producing high quality of products, effectively utilize the energy, minimizing is to the adverse effect of environment, and be easier to realize operating process and control, the renewal of technology is the core of development, the old technology drying machine power consumption of producing in the past is big, unfavorable to environment, technology difficulty is big, be difficult for realizing, based on these drawbacks, old product will certainly be eliminated.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of energy-saving and environmental protection, simple and reasonable, the gas-gas heat pump drier that is easy to realize are provided.
The technical scheme that the utility model adopted is: the utility model comprises compressor, condenser, expansion valve, evaporimeter, blower fan, drying box, dividing plate, described dry wall constitutes the dryer inner confined space, described drying box also is provided with feeding gate, described dividing plate is divided into hothouse with described confined space, the control room, described compressor, described condenser, described expansion valve, described evaporimeter places series connection formation periodic duty loop in the described control room, described blower fan is arranged on a side of described condenser in the described control room, the bottom in described control room also is provided with cistern, described cistern is connected with drip pipe, and the top of described hothouse is provided with homogenating plate.
Its workflow is: the gas mixed working fluid of heat pump fluid is after described compressor compresses, temperature raises, enter described condenser then, with working medium with heat pass to circulating air, working medium after the release heat enters described expansion valve and reduces pressure, and then enters described evaporator evaporation heat absorption, becomes low pressure steam state working medium, enter described compressor again, finish closed circuit thus one time.The circulating air temperature that the described condenser of flowing through absorbs behind the heat on every side raises, high temperature air enters described hothouse equably by described homogenating plate, contact with the material that is dried, make the water evaporates drying in the material, air becomes humid air thus, in the time of around humid air passes through described evaporimeter, thereby be subjected to described evaporimeter to absorb the heat cooling of surrounding air, be about to airborne moisture and become condensed water, flow into described cistern, discharged by described condensate draining pipe, humid air just becomes cold dry air, and deliver to described condenser again by the suction of described blower fan and absorb heat, so periodic duty.The air inlet place of described hothouse also is provided with standby electric heater, needs dry special material and during shortage of heat, carries out additional heat at drying machine.
The beneficial effects of the utility model are: drying system of the present utility model is worked under airtight environment, the heat energy utilization rate can reach more than 80%, system compares with conventional drying, energy-conservation more than 70%, environment is not had harm, and the thing that is dried is not contaminated yet, and it is simple and compact for structure, be easy to realize, so the present invention reaches the technical purpose of expection.
The utility model can be widely used in the sheet tablecloth hothouse of domestic food, cloth drying case, hotel and the fields such as drying shed that the industrial production product is used.
Description of drawings
Fig. 1 is a workflow schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises compressor 1, condenser 2, expansion valve 3, evaporimeter 4, blower fan 5, drying box 10, dividing plate 11, described drying box 10 constitutes the dryer inner confined space, allow drying system in airtight space, work, be energy-conservation, the guarantee of environmental protection, described dividing plate 11 is divided into hothouse 8 with described confined space, control room 12, described hothouse 8 is used for placing the withering material of needs, described drying box 10 also is provided with feeding gate 13, the thing that is dried is put into described hothouse 8 by described feeding gate 13 or is taken out from described hothouse 8, described compressor 1, described condenser 2, described expansion valve 3, described evaporimeter 4 places series connection formation periodic duty loop in the described control room 12, described blower fan 5 is arranged on a side of described condenser 2 in the described control room, the bottom in described control room 12 also is provided with cistern 9, described cistern 9 is connected with drip pipe 91, the top of described hothouse 8 is provided with homogenating plate 7, and described homogenating plate 7 makes the circulating air of flowing through disperse, flow into described hothouse 8 equably.
Its workflow is: heat pump fluid is after described compressor 1 compression, temperature raises, enter described condenser 2 then, with working medium with heat pass to circulating air, working medium after the release heat enters described expansion valve and reduces pressure, and then enters described evaporimeter 4 evaporation heat absorptions, becomes low pressure steam state working medium, enter described compressor 1 again, finish closed circuit thus one time.The circulating air temperature that the described condenser 2 of flowing through absorbs behind the heat on every side raises, high temperature air enters described hothouse 8 equably by described homogenating plate 7, contact with the material that is dried, make the water evaporates drying in the material, air becomes humid air thus, in the time of around humid air passes through described evaporimeter 4, the heat around described evaporimeter 4 absorbs in the humid air makes its cooling, and airborne moisture is become condensed water, condensed water flows into described cistern, discharged by described condensate draining pipe 91, humid air just becomes cold dry air again, and delivers to described condenser 2 absorption heats again by described blower fan 5 suctions, so periodic duty, because dryer inner is a confined space, and drying system is as the periodic duty system, therefore, the consumption of energy has seldom effectively reached energy-conservation, environment protecting.The air inlet place of described hothouse 8 also is provided with standby electric heater 6, needs dry special material and starts during shortage of heat at drying machine, and additional heat makes the circulating air of flowing through absorb sufficient amount of heat and enters hothouse.
Present embodiment is that technical conceive of the present utility model and characteristics are described, can not be with this qualification as the utility model protection domain, and the equivalence of being done according to the utility model substantial principle changes or modification, all within protection domain of the present utility model.
