As shown in Fig. 2, Fig. 3, Fig. 5, in the present invention in casing 1 and casing 1 outer between heat exchange mainly through having come except wet channel 9 and return air channel 10.Import except wet channel 9 is positioned at heating chamber 5 and is oppositely arranged with air outlet one 2b of evaporator room 2, outlet except wet channel 9 is positioned at kiln 4, owing to being oppositely arranged except the import of wet channel 9 and air outlet one 2b of evaporator room 2, therefore except stretching into air outlet one 2b that the rear level of main heating chamber 5 stretches to evaporator room 2 in one end of wet channel 9, the gas that the humidity that evaporator room 2 flows out is higher can be quick, preferential enters except wet channel 9, reduce the higher gas of these humidity to produce with the gas in heating chamber 5 and mix, reduce the loss of heat exchange, ensure that there is higher capacity usage ratio.And the import of return air channel 10 is positioned at kiln 4 and outlet is positioned at heating chamber 5, again can brings back to being positioned at the air of kiln 4 after dehumidifying heating chamber 5 and carry out next recycle.
As shown in Figure 3, Figure 4, total-heat exchanger 11 is also provided with in kiln 4, total-heat exchanger 11 has intersection but mutual disconnected first channel 11a and second passage 11b, first channel 11a are communicated with except wet channel 9 and vaporizer 7a, second passage 11b are communicated with vaporizer 7a and return air channel 10.Made the air-flow flowing to kiln 4 carry out heat exchange with the air-flow flowing to heating chamber 5 by total-heat exchanger 11, higher temperature is also had from kiln 4 air-flow out, about about 50 DEG C of air themperature in usual inflow first channel 11a, and the air themperature of second passage 11b is lower after dehumidification by condensation, about more than 20 DEG C, after total-heat exchanger 11 passes to second passage 11b the heat of first channel 11a, the air in first channel 11a is made to be cooled to about 30 DEG C in advance, the air of second passage 11b is heated in advance and probably can reach about 40 DEG C, accelerate the speed of cooling and heating, improve the efficiency of oven dry, further guarantee drying effect.Namely total-heat exchanger 11 tentatively can be lowered the temperature to the air-flow flowing to kiln 4, and tentatively heats to the air-flow flowing to heating chamber 5, and Appropriate application heat energy, to meet needs different separately, can save energy again simultaneously greatly.
In order to improve the efficiency of heat exchange further, the present invention is also provided with and the wind in kiln 4 can be pumped the blower fan 10a to heating chamber 5 in the exit of return air channel 10, the outlet of return air channel 10 arranges upward and its exit is also provided with air door 10b.This structure can reduce mutually to have an impact from evaporator room 2 air outlet one 2b effluent air to from return air channel 10 effluent air, the gas that these humidity are higher, temperature is lower is avoided to enter in return air channel 10, and by arranging the air olderly flowage that blower fan 10a and air door 10b can ensure in heating chamber 5 and kiln 4.
As shown in Figure 3, the diversion trench 2d that evaporator room 2 internal fixtion has some layers vertically to arrange one by one, each described diversion trench 2d has feed-water end 2d1 and water side 2d2, and the groove face of each described diversion trench 2d is arranged upward and the feed-water end 2d1 of the water side 2d2 of upper strata diversion trench 2d and lower floor adjacent guide groove 2d is positioned at the same side.The present invention makes the corresponding setting in feed-water end 2d1 position of the water side 2d2 of upper strata diversion trench 2d and lower floor adjacent guide groove 2d, therefore the waste water in every layer of diversion trench 2d can flow to water side 2d2 from feed-water end 2d1 in an orderly manner, whole waste water flowing-path is S-type, flow through path length, ensure enough evaporation areas, further increase vaporization efficiency.
As shown in Figure 3, the bottom of evaporator room 2 be also provided with can conveying solid substance precipitation transfer passage 8 and transfer passage 8 be connected with blast inlet one 2a.Transfer passage of the present invention 8 is with water tank 14 and arrange, the passage actually for being formed between water tank 14, orlop diversion trench 2d and evaporator room 2 sidewall.And solid-liquid separating equipment 3a is provided with in settling chamber 3, evaporator room 2 is being provided with sewage draining exit 2c near blast inlet one 2a place, conveying belt 8a is provided with in transfer passage 8, one end of conveying belt 8a is stretched in settling chamber 3 through dividing plate 1 and is connected with solid-liquid separating equipment 3a, and the other end stretches out sewage draining exit 2c.This structure can ensure that the solid precipitation transported out in settling chamber 3 can pass through the evaporation of the hot blast flow to by blast inlet one 2a, and the waste water that a part is remaining reevaporates, energy-efficient.Certainly, settling chamber 3 and heating chamber 5 are preferably laid respectively at the both sides of evaporator room 2 by the present invention, the throughput direction of conveying belt 8a is contrary with the air intake direction of evaporator room 2, ensure that solid precipitation has longer evaporation paths, ensure evaporation effect, and arrange contrary with evaporator room 2 air intake direction for the throughput direction of conveying belt 8a, ensure that solid precipitation effectively contacts with hot blast.
Be provided with solar absorber plate in solar energy heat absorbing room 6, solar energy heat absorbing room 6 is provided with blast inlet two 6a and air outlet two 6b in the side be connected with heating chamber 5.Blast inlet is arranged on the same side with air outlet two 6b, can ensure that this two air-flow combines and can produce vortex in the inside of heating chamber 5, gas temperature after heating chamber 5 top is preheated is more even, and the more uniform efficiency that gas is heating through scatterer 7b of temperature is higher.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
