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 making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The closed barn for tobacco flue-curing as shown in Figure 1, comprise airtight equipment room 1 and airtight cigarette-filling house 2, dividing plate 20 is provided with, by being arranged on air outlet 9 on dividing plate 20 and return air inlet 10 communicates between equipment room 1 with cigarette-filling house 2 between equipment room 1 and cigarette-filling house 2; The high-temperature dehumidification heat pump all-in-one 18 arranged for the supply of barn heat and moisture is provided with outward in equipment room 1, high-temperature dehumidification heat pump all-in-one 18 comprises compressor 3, gas-liquid separator, condenser 6, auxiliary condenser 4, evaporimeter 12, cross valve, heat exchanger 5 and outer circulation blower fan 13, high-temperature dehumidification heat pump all-in-one 18 upper end is connected to Inner eycle blower fan 7, lower end is communicated with return air inlet 10, and Inner eycle blower fan 7 is connected with air outlet 9 by supply air duct 8; Also be connected with drip tray 16 bottom auxiliary condenser, drip tray 16 is connected with drainage pipeline 17, and the end of drainage pipeline 17 is placed in outdoor.
Equipment room 1 wall offers the open and close type carrying out ventilating for moment and leads to oxygen hole.
Detachable movable cigarette frame 19 is also provided with in cigarette-filling house 2.Be conducive to the installation and removal of cigarette frame on the one hand, spacing on the same stage can be done not to the tobacco leaf of different cultivars, different parts on the other hand and regulate.
Inner eycle blower fan 7 adopts centrifugal fan.Centrifugal blower has the advantages that blast is large, lift is far away, effectively can solve the drawback that axial-flow type circulating fan exists.
Gas-liquid separator adopts the gas-liquid separator with regenerative apparatus, to increase the degree of superheat of compressor 3 return-air, ensures that return-air is gaseous state, prevents compressor 3 from occurring liquid hit phenomenon, and can increase the degree of supercooling that condenser 6 exports cold-producing medium, improves throttle efficiency.
Heat exchanger 5 adopts crossflow heat exchanger.The gas entering cross flow heat exchanger from barn carries out heat exchange with the dehumidifying gas that temperature reduces afterwards, and the gas entered by barn can be improved dehumidification rate by precooling, and the gas after dehumidifying is preheated and can improves intensification efficiency.
Equipment room 1 and cigarette-filling house 2 adopt total closed type structure, build by light thermal insulation board is removably integrally closed.Its material optimization polyurethane composite sandwich panel, thickness is not less than 50mm, warming plate is reserved with installing hole and connector, and warming plate as required, is fixedly connected with by connector bolt or screw by scene.This material is light, good heat preservation performance, easy installation and removal, overcomes the fixing building structure mode of traditional baking chamber.Cigarette frame 19 can be steel, panel beating or aluminium alloy extrusions, according to cigarette-filling house 2 size, can carry out extendible installation.Compressor 3 is to adopt vortex compressor, piston compressor or screw compressor; Preferentially scroll compressor is adopted for small unit.Condenser 6 is made up of base tube and the fin be arranged on base tube; Base tube can adopt bronzing pipe or inner screw thread copper pipe; Fin is aluminium, copper product, and fin can be that corrugated plate, sun-roof or ripple are sun-roof etc.
This operation principle being used for the closed barn of tobacco flue-curing is: syndeton Integral sealing between insulation closed barn body of wall, the heat that heating equipment provides sends into cigarette-filling house by centrifugal fan by air channel, and heat can not pass through cigarette-filling house's wall, ceiling and bottom surface and run off.According to the required difference of different phase in Tobacco Leaf Curing, roasting plant can provide intensification, dehumidifying, cooling three kinds of modes to meet tobacco flue-curing demand.
As shown in Figure 2, in the temperature rise period, cold-producing medium is under compressor 3 acts on, be converted to high-temperature high-pressure refrigerant gas, high-temperature high-pressure refrigerant gas arrives condenser 6 by copper pipe, liquefaction has heat to release, and enters auxiliary condenser 4 liquidation exothermic reaction further after cross valve, by circulating fan 7 and even mixed wind air channel 8, heat is sent into barn.High-temperature high-pressure refrigerant gas exothermic condensation in condenser 6 and auxiliary condenser 4 is the refrigerant liquid of HTHP, enters into evaporimeter 12 by becoming low-temperature low-pressure refrigerant liquid after throttling arrangement 21.Now, the outer blower fan 13 in external circulating system runs and the gas at normal temperature in external environment condition is sucked internal circulation system, and the latent heat of normal temperature air is absorbed after evaporator 12, enters into refrigerant-cycle systems.Now low-temp low-pressure liquid refrigerant is evaporated to low-temp low-pressure gaseous refrigerant, and the low-temp low-pressure gaseous refrigerant completing heat absorption work in evaporimeter gets back to compressor 3, completes an outer loop.
As shown in Figure 3, need moisture outer row's stage at tobacco leaf, equipment is converted to operation dehumidification mode.By condenser 6 out in warm high pressure refrigerant liquid, enter evaporimeter 12, under the effect of circulating fan 13 outside, carry out heat exchange with surrounding air, regulate barn humiture balance.Then cold-producing medium is converted to Low temperature low pressure liquid by throttling arrangement 21, and low-temp low-pressure liquid refrigerant enters auxiliary condenser 4, dehumidifies to the hot and humid air entered by barn.Gas in barn is under the driving of Inner eycle blower fan 7, the damp-heat air of barn inside is through return air inlet 10 forced refluence, increase moisture reflux speed, the auxiliary condenser 4 being placed in device interior is flowed through from the high temperature moisture of barn backflow, vaporous water steam is liquefied as cooling water, cooling water flows into drip tray 16, is discharged to outdoor through drainage pipeline 17.By auxiliary condenser 4 out in wet body enter condenser 6 and heat up, become dry hot blast, finally by air channel 8, hot blast delivered to barn by air outlet 9 by Inner eycle blower fan 7, tobacco leaf is toasted, completing dehumidifying circulation.Due to barn and device structure Integral sealing, inner air does not have heat and air-flow to exchange with external environment, the tabacco fragrance therefore flowing into equipment room through return air inlet 10 is sent back to barn again through air channel 8 and Inner eycle blower fan 7, improves tobacco incense tolerance.
As shown in Figure 4, tobacco leaf cooking process needs to maintain constant temperature humidity and carries out tobacco flue-curing, because tobacco flue-curing has tobacco leaf spontaneous heating phenomenon early stage, meets constant temperature moisture requirement in Tobacco Leaf Curing by the cooling function of high-temperature dehumidification heat pump all-in-one.Be specially: when temperature in barn is higher than actual needs baking temperature, refrigerant compression is high temperature and high pressure gas by compressor 3, directly enter evaporimeter 10, auxiliary condenser 4 is entered after throttling arrangement 21, barn hot and humid gas is dehumidified, dehumidifying after temperature reduce dry air get back to barn, in order in and barn in due to the spontaneous thermogenetic waste heat of tobacco leaf, reach the object of barn temperature constant.
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.
