The specific embodiment
As shown in Figure 1, the twin-stage regeneration dehumidification system for runner described in the present invention, mainly comprises dehumidification system and regenerative system,
Above-mentioned dehumidification system comprises dehumidifying section, the secondary evaporimeter 4 of new wind filter 1, one-level evaporimeter 2, one-level runner 3, dehumidifying section, heater 6 and the breeze fan 7 of secondary runner 5, wherein new wind filter 1 contacts with external environment, and breeze fan 7 is sent into indoor by the air after processing; Above-mentioned regenerative system comprises regenerator section, first-stage condenser 10, the regenerator section of one-level runner 3 and the blower fan 11 of regenerating of regeneration wind filter 8, secondary condenser 9, secondary runner 5, the wind filter 8 of wherein regenerating contacts with external environment, and regeneration blower fan 11 drains into the air after rotary wheel regeneration in environment.One-level evaporimeter 2 and first-stage condenser 10 belong to same compressed steam kind of refrigeration cycle; Secondary evaporimeter 4 and secondary condenser 9 belong to same compressed steam kind of refrigeration cycle.Compressor and expansion valve in figure, have been omitted.
Air handling process: first new wind remove impurity through new wind filter 1, then through one-level evaporimeter 2, reduce temperature and improve relative humidity, dehumidifying section at one-level runner 3 is eliminated part water capacity through wheel solid adsorption and dehumidification, now due to adsorbent moisture absorption heat release in runner 3, new air temperature raises to some extent, again through secondary evaporimeter 4 cooling, subsequently the dehumidifying section by secondary runner 5 by humidity be down in indoor claimed range, send into indoor; If the air after secondary runner 5 cannot reach indoor wind pushing temperature, after can 6 pairs of air of heater heating, by processing blower fan 7, send into indoor.
Rotary wheel regeneration process: first outdoor new wind remove impurity by regeneration wind filter 8, pass through subsequently secondary condenser 9 heat temperature raisings, air after intensification is taken away the moisture of secondary runner 5 absorption through the regenerator section of secondary runner 5, adsorbent desorption heat absorption in secondary runner 5, air themperature decreases, now pass through first-stage condenser 10 heat temperature raisings, then be by outside regeneration blower fan 11 discharge chambers after one-level runner 3 desorptions.
When system is specifically moved, treatment system and regenerative system are worked simultaneously, and air handling process and rotary wheel regeneration process are carried out simultaneously.In air handling process, new wind removes through filter 1 impurity such as dust that contain, and avoids runner inner passage blocked; After removing impurity, in one-level evaporimeter 2, reduce temperature raising relative humidity, improved steam partial pressure, promoted the effect on moisture extraction of runner 3; In runner 3 dehumidifying section dehumidifying, by secondary evaporimeter 4, eliminate the heat producing because of solid moisture absorbent moisture absorption, by secondary runner 5, humidity is adjusted to indoor required scope on this basis, if now temperature meets the demands, directly by processing blower fan 7, send into indoor; If do not meet the demands, use send into after heater 6 heating indoor.In rotary wheel regeneration process, use equally outdoor new wind as air-source, new wind, through filter 8 impurity screenings, is sent into the regenerator section of secondary runner 5 in secondary condenser 9 after being heated, promote its desorption; In first-stage condenser 10, heat absorption recovers higher regeneration temperature, thereby the regenerator section of one-level runner 3 is carried out to desorption; After this process completes, damp atmosphere is drained in environment by the blower fan 11 of regenerating.
As shown in Figure 2, in one-level runner 3, dehumidifying section is 12, and regenerator section is 13, and the ratio of dehumidifying section 12 and regenerator section 13 areas is 1:1, and now rotary wheel regeneration temperature is moderate; In actual applications when require the ratio of dehumidifying section 12 and regenerator section 13 areas when larger to can be adjusted to 3:1 to system dehumidification air quantity, but now required regeneration temperature is higher, and energy consumption increases.Be that in described one-level runner 3, the area ratio of dehumidifying section and regenerator section is 1:1-3:1, specifically by actual conditions, determined.
As shown in Figure 3, in secondary runner 5, dehumidifying section is 14, and regenerator section is 15, and the ratio of dehumidifying section 14 and regenerator section 15 areas is 1:1, and when larger to the requirement of system dehumidification air quantity, the ratio of dehumidifying section 14 and regenerator section 15 areas also can be 3:1 in actual applications.Now rotary wheel regeneration temperature is moderate; In actual applications when require the ratio of dehumidifying section 14 and regenerator section 15 areas when larger to can be adjusted to 3:1 to system dehumidification air quantity, but now required regeneration temperature is higher, and energy consumption increases.Be that in described secondary runner 5, the area ratio of dehumidifying section and regenerator section is 1:1-3:1, specifically by actual conditions, determined.
Compared with former rotary wheel dehumidifying method, the processing to wind pushing temperature that twin-stage regeneration dehumidification system for runner is integrated, installing space is less more flexible; And take full advantage of condensation heat and replace electrical heating, reach energy-conservation object; In addition the mode of classification has also more effectively been utilized the energy and has been improved system redundancy.
