It can be applied in various products related to daily life, such as air cleaning devices and medical therapy systems. The invention combines the concepts of environmental protection and knowledge of frontier science. It is applicable in various fields and different products, with the potential to enhance productivity and competitiveness.

Problems solved by technology

Nevertheless, regeneration processes of these absorptive materials are usually energy consumption.
Besides, the regeneration temperatures are usually hard to control.
During such regeneration processes, high temperature will also decompose and destroy the cellulose structure of the adsorbent carbon.
Though, the adsorptive materials can be regenerated continuously, the method is not environmentally sound as power is consumed continuously.
Stable temperature may not able to achieve for such regeneration, as the sources of heat are not described.
Accumulation of VOCs at the downstream position and ignite it by combustion create potential fire hazard.
The regeneration method is not handy and economical viable since electricity is required for the continuous operation of this device.
Moreover, the generation of oxygen gas is expensive.
The processes are clumsy, energy and time consuming, as a very high temperature and pressure are required.
The adsorbent bed is heated to release the contaminants into the fixed volume and this process creates a high concentration of contaminants within the fixed volume.
Apart from this, the above-mentioned regeneration processes are not handy and must carried out under the present of complicated setup.

The Heat Recycling System is Employed in an Air Freshening System In-vehicle

[0059] The designs of FIG. 1 to 7 are employed in this example. The absorptive materials contains 100 g zeolite 4A which was pretreated by soaking into 30 g of aroma solution (10-40% lavender oil and 60-90% isopropanol) followed by air drying. The thermal storage materials contain of 50-65 g Magnesium Nitrate and 35-50 g water. The mixture was allowed to heat until all magnesium nitrates was dissolved.

[0060] The phase change temperature for the thermal storage materials is 55° C.-62° C. During it phase change; the aroma oil will be released slowly and stably to the environment.

The Heat Recycling System is Employed in an Air Freshening System In-vehicle

[0061] The designs of FIG. 1 to 7 are employed in this example. The absorptive materials contains 100 g zeolite 4A which was pretreated by soaking into 30 g of aroma solution (10-40% rose oil and 60-90% isopropanol) followed by air drying. The thermal storage materials contain of 17-25% calcium chloride and 17 to 25% water. The mixture was allowed to heat until all calcium chloride was dissolved.

[0062] The phase change temperature for the thermal storage materials is 27° C.-31° C. During it phase change; the aroma oil will be released slowly and stably to the environment.

[0063]FIG. 10 indicates the temperature conditions when the heat recycling system was employed in a vehicle which was packing out door. Since the vehicle was irradiated by the outdoor sunshine, the longer wavelength infra-red light was not able to escape after entered into the vehicle. The temperature inside the vehicle therefore increase...

Mosquitoes Repelling Device

[0064] The designs of FIG. 1 to 7 are employed in this example. The absorptive materials contains 100 g zeolite 13A which was pretreated by soaking into 5 g of mosquitoes repelling solution (20-40% citronella oil, 5-10% diethyl-m-toluamide and 50-70% isopropanol) followed by air drying. The thermal storage materials contain of 50-65 g Magnesium Nitrate and 35-50 g water. The mixture was allowed to heat until all magnesium nitrates was dissolved.

[0065] The phase change temperature for the thermal storage materials is 55° C.-62° C. During it phase change; the mosquito's repelling solution will be released slowly and stably to the environment.

Abstract

A heat recycling system that regenerates absorptive materials for a sustainable period of time with the help of thermal storage materials. The system may contain absorptive materials and thermal storage materials which absorb wasted thermal energy from the surroundings.

Description

FIELD OF THE INVENTION [0001] The present invention is related to a regeneration system for absorptive materials. In the invention, the thermal storage materials are used. It is aimed at regenerate the absorptive materials under a constant temperature for a sustainable period and recycling the unused thermal energy. When operate, the thermal energy is being absorbed and stored into the thermal storage materials. It is then transferred to kinetic energy for chemicals molecules which are resided in the pores of the absorptive materials. Subsequently, the released chemical molecules may be further be decomposed if it is an air cleaning device, or for other functional usage according to the design of the product. BACKGROUND [0002] For many years, absorptive and absorptive materials are employed to adsorb and absorb some target substance which may be either desirable or non-desirable to mankind. For example, molecular sieves, zeolites or activated carbon materials are employed to adsorb ...
