Embodiment 1

[0024] A dehumidification system such as figure 1 with figure 2 As shown, including: a first induced draft fan 1, a first membrane contactor 2, a heater 3, a second induced draft fan 4, a second membrane contactor 5, a cooler 6, a liquid storage tank 7 and a solution pump 8, the The solution pump 8 pumps the dehumidification solution in the liquid storage tank 7 to the first membrane contactor 2, so that the dehumidification solution moves out and flows through the first membrane contactor 2, the heater 3, the second membrane contactor 5 and the cooler 6 After that, it flows back into the liquid storage tank 7; the first induced draft fan 1 makes the air to be dehumidified flow through the first membrane contactor 2 for dehumidification, and the second induced draft fan 4 makes the outside air flow through the second membrane contactor 5 to remove water vapor in the dehumidification solution, the first membrane contactor 2 and the second membrane contactor 5 both include a h...

Embodiment 2

[0093] A humidification system such as Figure 6 As shown, it includes an induced draft fan 11, a membrane contactor 12, a liquid storage tank 13, a solution pump 14 and a heater 15, and the solution pump 14 pumps the distilled water in the liquid storage tank 13 into the described heater 15, To make the distilled water return to the liquid storage tank 13 after passing through the heater 15 and the membrane contactor 12, when the air is humidified, the air is sent into the membrane contactor 12 by the induced draft fan 11; The distilled water is driven by the solution pump 14 and sent into the membrane contactor 12 . Air flows on the shell side of the membrane contactor 12 and flows through the tube bundle along (parallel to) the direction of the minor axis of the ellipse; the distilled water heated by the heater 15 flows in the membrane fiber tube. Under the action of the vapor pressure difference, the gas and liquid conduct indirect water vapor heat and mass exchange throu...

Abstract

The invention provides a hollow fiber membrane contactor and a humidification / dehumidification system using the hollow fiber membrane contactor. Compared with the prior art, the membrane contactor comprises a membrane fiber tube of which the cross section takes the shape of an ellipse, the flowing direction of first fluid which flows in a shell is parallel to a short axis of the ellipse, mathematical calculation and data simulation show that by adopting the design, the nusselt number is greatly increased when air transversely sweeps the membrane fiber tube in the membrane contactor, although the average resistance coefficient is increased to certain extent, comprehensive heat conduction factors are greatly improved, the heat exchange capability of the membrane contactor is greatly improved under the condition of identical membrane contact areas, and the steam conduction efficiency can be greatly improved under the condition of membranes of equal areas in the humidification / dehumidification system, so that the efficiency of the humidification / dehumidification system is improved.

Description

Technical field [0001] The invention involves the field of air humidity control technology, which specially involves a hollow fiber film contactor for air humidity control, and air dehumidification systems and air humidification systems using the air fiber membrane contactor. Background technique [0002] Air humidity has an extremely important impact on people's daily aspects.The air humidity is too high or too low, which is not conducive to the development and operation of production and life.In humid air, foods are easy to deteriorate, and paper products such as books are also easily affected and deformed; mold will breed on the surface of some buildings. If it is accumulated for a long time, it will affect indoor air quality.The health of indoor personnel is harmful.At the same time, it is easy to produce static electricity in a dry environment, which is very unfavorable for the safe operation of industrial production and some electronic products such as some computer equipme...
