The specific embodiment
See figures.1.and.2, drying room provided by the invention dehumidifying residual neat recovering system, comprise by the baking room 16 of partition wall 15 isolation be connected between 3 drying rooms that form 1, with described heating between 3 two dehumidifiers 6 that are connected; Be provided with some baking racks 14 in the baking room 16, the bottom of baking room 16 sides is provided with moistureproof window 13, be provided with electric calorifie installation in 3 between heating, electric calorifie installation comprises support 10 and the electric heater 9 that is located on the support 10,3 were divided between electric calorifie installation will heat, lower two parts, between heating 3 upper, the bottom is respectively equipped with dehumidifying air inlet 5 and dehumidifying air outlet 11, the top that is positioned at described dehumidifying air inlet 5 between heating in 3 is provided with air inducing fan 4,3 are provided with the new wind entrance 8 of movable air door 7 between electric calorifie installation and dehumidifying air inlet 5 between heating, and the upper and lower of partition wall 15 is respectively equipped with, lower blow vent 2,12 with between described heating 3 upper, the bottom is communicated with described baking room 16 respectively; Described dehumidifier 6 as shown in Figure 3, be air-cooled dehumidifier, comprise airtight cylindrical shell 601, the bottom of cylindrical shell 601 and top are respectively equipped with air inlet 604 and gas outlet 603, be provided with some airducts 602 that are communicated with cylindrical shell 601 outsides in the cylindrical shell 601, described airduct 602 vertically is built up in the cylindrical shell 601, the air inlet of airduct 602 and air outlet are located at respectively bottom and the top of cylindrical shell 601, cylindrical shell 601 is provided with self-draining arrangement, and self-draining arrangement comprises the drainpipe 607 and the water level controller that is connected with magnetic valve 17 (not drawing) of the provided with electromagnetic valve 17 that is located at cylindrical shell 601 bottoms; The air inlet 604 of cylindrical shell 601 are connected with the gas outlet respectively with described heating between dehumidifying air outlet 11 be connected with the air inlet 5 that is connected; Dehumidifying air outlet 11 between the air inlet 604(of cylindrical shell 601 or heating) is provided with dehumidifying fan 605, is provided with chilled air fan 606 before airduct 602 air inlets of cylindrical shell 601 bottoms.
During drying room 1 work of the present invention, material such as flue-cured tobacco etc. hang on the baking rack 14, open between electric calorifie installation and heating the air inducing fan 4 in 3, make between the baking room 16 of drying room and heating that the upper and lower blow vent 2,12 by partition wall 15 forms the cycling hot air-flows between 3, thermal current forms hot and humid gas after with the evaporation of the moisture in the material.Hot and humid gas is 3 interior formation two-way air-flows between heating, one the tunnel is directly heated by electric calorifie installation, another road enters dehumidifier 6 dehumidifying from dehumidifying air outlet 11, hot and humid gas water content after dehumidifying reduces greatly, reenter between heating and to mix participation with direct-fired hot and humid gas in 3 and circulate, so that the water content of hot and humid gas is lowered after mixing, so circulation is progressively with drying materials.When the baking operation, can require to utilize movable air door 7 to open or close fresh wind port 8 according to dehumidifying and replenish fresh air, utilize the moistureproof window 13 of baking room 16 to carry out direct hydrofuge.
Air-cooled dehumidifier dehumidifying among the present invention main cooling medium that is air colder in the external environment condition in the dehumidifier, utilize the chilled air fan 606 of dehumidifier cylindrical shell 601 bottoms to allow colder air airduct 602 interior flowing, when 3 hot and humid gas of discharging passed through the cylindrical shell 601 of dehumidifier between utilization dehumidifying fan 605 will heat, airduct 602 outer walls in hot and humid gas and the cylindrical shell 601 contact and carry out heat exchange, because airduct 602 internal-external temperature differences are larger, moisture in the hot and humid gas just can condense into the globule around airduct 602 outer walls, the globule once gathering together more, flow to cylindrical shell 601 bottoms along airduct 602, when the water that condenses in the dehumidifier reaches designated water level, magnetic valve in the self-draining arrangement will be opened by drainpipe 607 water will be discharged rapidly, behind the drained water, magnetic valve is with drainpipe 607 autoshutdowns.Since dehumidifier be utilize condensing mode dehumidifying and be provided with air inlet 604 and gas outlet 603 and heating between 3 communicate, so the gas after dehumidifying still keeps higher temperature, this part heat energy is brought back into again between heating 3 and is utilized.
Water-cooled dehumidifier among the present invention is to replace cold air in the air-cooled dehumidifier as cooling medium take water, utilizes cyclic water tank allow and circulates in the water pipe of colder water in dehumidifier, and its operation principle is identical with the water-cooled dehumidifier.
Air-cooled and application two kinds of dehumidifiers of water-cooled can be energy-conservation more than 20%-30% with respect to existing roasting plant.
When the ambient temperature of roasting plant is lower than inner baking temperature more than 15 ℃, can adopt air-cooled hydrofuge.Water-cooled hydrofuge technology requires not quite the inside and outside temperature difference of roasting plant, because water temperature is lower, and apparent wind cold type hydrofuge technology, the water-cooled hydrofuge is easier to form the globule, and the hydrofuge effect is relatively quite a lot of.
Two kinds of hydrofuge equipment can be installed according to the different weather in various places, and air-cooled hydrofuge can be selected in the colder area of temperature, and the water-cooled hydrofuge can be selected in the area that temperature is higher.
