Description
Technical Field
The invention belongs to the field of drying and dehumidifying, and particularly relates to a drying treatment system and a drying treatment method.
Background
In each field such as food package, material processing, pharmaceutical production, often need use dry dehumidification technique, current dry dehumidification technique mainly has following several:
1. manual processing formula drying house:
the drying room controls the temperature and the humidity of an area, and people put materials into the room, stand the materials until the drying is finished, and then take the materials out; the disadvantages are that:
A. in order to increase the placing space, the dehumidifying and drying room has huge space volume, and large investment and energy consumption are realized by controlling equipment with large circulating air volume, the temperature and the humidity of which need to be matched;
B. because the required personnel directly enter the dehumidification environment, the temperature and the humidity of the dehumidification room are subject to the temperature sensing requirements of the human body, on one hand, the process requirements of material drying are required to be met, and on the other hand, the requirement of the comfort degree of the human body is required to be considered, so the freedom degree of system design is further limited, and greater energy waste and the cost of matched equipment are increased;
C. a large amount of outdoor air enters the drying system inevitably due to the fact that people enter and exit the drying system, and uncertain energy consumption is increased due to the fact that the moisture is produced by the people, and meanwhile the drying effect is influenced;
D. because the state in the drying room is influenced by a plurality of factors and only the personnel can carry out sampling inspection by experience to confirm whether the drying room achieves the drying target, great difficulty is brought to production management, and the generated stability cannot be ensured.
2. An automatic dehumidifying and drying room, as shown in fig. 1:
this drying room sets up a plurality of lateral expansion, and relatively independent can hold the drying space 17 of dry material for the conveyer belt 12 of transported substance passes each drying space 17 in proper order, is equipped with wind-driving device 28, temperature control device 29 between two adjacent drying space 17, and automatic formula dehumidification drying room has following defect:
A. the existing drying air vertically penetrates through the surface of the material and conveying endless belt 12, and the wind resistance is very large;
B. the inflow and outflow of the materials and the space between the adjacent heating and dehumidifying sections are provided with large open channels, the ideal closed space is actually changed into an open space, and a large amount of wind returns to the next stage from the previous stage or enters the drying space 17 from the external space; so that the flow rate of the air flowing through the adjacent drying space 17 is much smaller than the air volume of the blower, especially in the case of a relatively large wind resistance; the effective utilization rate is extremely low, and the controllability of the humidity and the temperature is greatly reduced;
C. because of the series connection relationship in the drying process, although the problem of the relative humidity of the next-stage inlet air can be solved by a heating mode, the moisture content in the air is greatly increased essentially, and the heating temperature of the subsequent dehumidification heating section is required to be increased gradually;
D. for the reasons, only the following measures are taken to ensure the drying effect:
the stacking area of the materials is increased, the method has large space limitation, and the defects are further enlarged;
the method is limited by the head-on wind speed, the energy consumption is huge due to overhigh head-on wind speed, and the series flow is serious due to overhigh wind speed, so that the scene drying is controlled.
E. Due to the existence of the series flow phenomenon, when the air which absorbs moisture in a large amount in the upper stage enters the upper stage in series flow, the relative humidity of the air is increased due to the temperature reduction, and the drying effect is seriously influenced;
F. in the existing drying mode, the theoretical temperature, the theoretical humidity and the theoretical wind speed in each heating and dehumidifying section are fixed, cannot be adjusted according to actual needs, and cannot adapt to various actual needs of different materials, different seasons, different climates, different links and the like; if debugging is needed, professional personnel are needed to perform the debugging;
G. even so, in a general real scene, due to the above-mentioned defects, there is a very big gap between the control of theoretical temperature, humidity, wind speed, etc. and the situation in actual operation, and the control in operation is more in an uncontrollable state, and the energy consumption is very large.
