The specific embodiment
Embodiment 1
A kind of heat exchanger of tobacco flue-curing house as shown in Figure 1, it comprises the hot gas approach 1 of stove, preceding plenum chamber, heat exchanger tube, back plenum chamber 7, smoke evacuation chimney 4, the two ends of heat exchanger tube link to each other with back plenum chamber 7 with preceding plenum chamber respectively and form flue gas turnover path, the middle part design of preceding plenum chamber has the preceding plenum chamber dividing plate 12 of level, before plenum chamber dividing plate 12 preceding plenum chamber is divided into before chamber 3 under chamber 10 and the preceding plenum chamber on the plenum chamber, the heat exchanger tube that links to each other with chamber 3 under the preceding plenum chamber is a backhaul heat exchanger tube 8, what link to each other with chamber 10 on the preceding plenum chamber is two return heat exchanger tube 6, before under the plenum chamber chamber 3 link with the hot gas approach 1 of stove and by a backhaul heat exchanger tube 8, back plenum chamber 7, chamber 10 links on two return heat pipe 6 and the preceding plenum chamber, before smoke evacuation chimney 4 is installed on the plenum chamber top and with preceding plenum chamber on chamber 10 link.Heat exchange tube design is and corresponding many of hot flue gas flow that the staggered certain position of the upper and lower employing of heat exchanger tube is arranged.Design has two shoot doors 2 of position symmetry on the preceding plenum chamber front side wall, and shoot door (not drawing among the figure) is arranged at back plenum chamber bottom also design; Before between plenum chamber and the back plenum chamber by the screwed assembling in two ends fixedly wire drawing 5 is connected, heat exchanger tube and preceding plenum chamber and after the design of plenum chamber connecting portion seal washer 9 is arranged, designing below the back plenum chamber has support column 11.
This heat exchanger of tobacco flue-curing house is applied to the standard cured tobacco curing house.It is respectively 8000mm, 2700mm, 3500mm that the standard cured tobacco curing house is hung the smoke-box length, Heat Room, heat exchanger and biomass block monomer flue-cured tobacco stove are supporting, the Heat Room length is respectively 1800mm, 1600mm, 3500mm, the heating load of flue-cured tobacco stove is 330Mj/ hour, consume biomass straw briquetting 35kg/h, 90min is heated to 80 ℃ to the temperature of being unkitted in the empty standard cured tobacco curing house of fresh tobacco leaf during big fire, meets the requirement of the relevant flue-cured tobacco standard that national tobacco general bureau formulates.
Operation principle:
The operation principle of cured tobacco curing house heat exchanger is: with the outer surface of the circulating fan transversal flow flue-cured tobacco heat exchanger of installing in the cured tobacco curing house, the heat of hot flue gas in the heat exchanger is cemented out, be used for baking tobacco leaves.Chamber 3 under the plenum chamber before this heat exchanger high-temperature flue gas enters from the hot smoke inlet 1 of stove, flow into a backhaul heat exchanger tube 8 in indoor sub-distribution just, entering back plenum chamber 7 again mixes, chamber 10 on the plenum chamber through two return heat exchanger tube 6 enters before respectively after making mixed flue-gas temperature evenly is at last from 4 discharges of smoke evacuation chimney; The tobacco flue-curing house circulating fan air-supply Heat Room of flowing through, from above or below the transversal flow heat exchanger one, two return heat exchanger tube and forward and backward plenum chamber outer surface, radiation, conduction, the heat that flows out is taken away, send into the tobacco flue-curing house baking tobacco leaves.The transversal flow heat exchanger makes it can obtain bigger heat exchange efficiency, and it is the dust stratification that mixes, distributes the hot flue gas and the sedimentation of a backhaul heat exchanger tube 8, two return heat exchanger tube 6 and store up heat exchanger temporarily that plenum chamber mainly acts on.One backhaul heat exchanger tube 8, two return heat exchanger tube 6 are critical pieces of " gas---gas " heat exchanger, and effect is heat exchange and the passage of doing high-temperature flue gas.Hot smoke inlet 1 pipe of heat exchanger mainly is to connect flue-cured tobacco stove and heat exchanger, and the effect of smoke evacuation chimney 4 is to discharge the low-temperature flue gas after the heat exchanger heat exchange outdoor.On the preceding plenum chamber two shoot doors 2 are housed, make things convenient for the dust stratification in the periodic cleaning heat exchanger.
The heat exchanger of tobacco flue-curing house job step:
1. start the tobacco flue-curing house circulating fan.
2. light biomass block flue-cured tobacco stove, at this moment entered the normal operating conditions of heat exchanger, carry out heat exchange.
3. behind the end-of-job, should stop biomass block flue-cured tobacco stove (stopping working) earlier, after stop the tobacco flue-curing house circulating fan.Forbid heat exchanger of tobacco flue-curing house when not moving circulating fan, to carry out heat exchange.
4. the dust stratification of inner space such as heat exchanger heat-exchanging tube and pneumatosis case should be cleared up once by every a heatable brick bed.
