Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
embodiment 1
As shown in Figure 1, a kind of air disinfection and decontamination system, system is by having refrigeration or the heat energy apparatus 1 of heat-production functions, blower fan 4 and pipeline form, and heat energy apparatus 1 is connected with blower fan 4 by pipeline; Described heat energy apparatus 1 comprises element 11.Described element 11 can be heating element heater or cooling module, described heating element heater is selected from electrical heating elements, or be water heating elements, steam heating elements, refrigerant heat element (as freon etc.), air or flue gas element, cooling module is selected from water cooling module, cold fluid cooling module (as ethylene glycol etc.), chiller refrigeration element (as freon etc.).
The process of this system sterilizing is as follows: the air A1 from a certain space is heated through heat energy apparatus 1 or cooledly becomes TA, antibacterial, virus etc. is killed, after air TA rises again with the air A1 mixing realization without heat energy apparatus (1) again, become SA, send into this space.
The temperature of TA, different and different according to the kind of the harmful substances such as the antibacterial in air or virus, be generally greater than 50 degree when heat treated, freezing when processing is less than 0 degree, when also can heat by Temperature Treatment to more than 100 degree or higher.
The sterilizing of air A1 can use the method for cold and hot combined treatment, and namely A1 is first through heating, then through supercooling, or first cool, then heat, then mix with the air A1 without heat energy apparatus 1.The situation of combination is not indicated in Fig. 1.
In present embodiment, owing to only partial air and A1 being heated or cooling, so required energy is less.
embodiment 2
As shown in Figure 2, a kind of air disinfection and decontamination system, it is characterized in that, system forms by having the heat energy apparatus 1, heat reclamation device 2, blower fan 4 and the pipeline that freeze or heat, heat reclamation device 2 comprises the inlet channel and outlet passageway that are alternately arranged, and described inlet channel, heat energy apparatus 1, outlet passageway, blower fan 4 are connected by pipeline successively; Described heat energy apparatus 1 comprises element 11, described element 11 can be heating element heater or cooling module, described heating element heater is selected from electrical heating elements, or be water heating elements, steam heating elements, refrigerant heat element (as freon etc.), air or flue gas element, cooling module is selected from water cooling module, cold fluid cooling module (as ethylene glycol etc.), chiller refrigeration element (as freon etc.).
The process of this system sterilizing is as follows: the air A from a certain space to be first preheated or pre-cooling becomes PA through the inlet channel of heat reclamation device 2, heated through heat energy apparatus 1 again or cooledly become TA, the outlet passageway eventually passing heat reclamation device 2 is cooled or heats and becomes SA, then this space is sent into, antibacterial, virus is in above-mentioned 3 processes, and namely A becomes PA, PA becomes TA, and TA becomes in the process of SA and progressively killed.
In the present embodiment, becoming TA process owing to only having PA has outside energy to input, so required energy is less.
The temperature of TA, different and different according to the kind of the harmful substances such as the antibacterial in air or virus, be generally greater than 50 degree when heat treated, freezing when processing is less than 0 degree, when also can heat by Temperature Treatment to more than 100 degree or higher.
The sterilizing of air A can use the method for cold and hot combined treatment, namely air A is first through heat treatment process, namely the inlet channel through heat reclamation device 2 is preheated, heated through heat energy apparatus 1 again, the outlet passageway eventually passing heat reclamation device 2 is cooled, then through cold-treating process, namely through the inlet channel of second heat reclamation device by pre-cooling, pass through another heat energy apparatus more cooled, the outlet passageway eventually passing second heat reclamation device is heated.Or air A is first through cold-treating process, then through heat treatment process, in Fig. 2, do not represent the situation of combination.
embodiment 3
As shown in Figures 3 and 4, described heat energy apparatus 1 and heat reclamation device is 2-in-1 is integrated, namely system is directly made up of element 11, multiple heat exchange wall 31 and blower fan, and form inlet channel or outlet passageway between two adjacent heat exchange walls 31, inlet channel or outlet passageway are alternately arranged; Inlet channel, element 11, outlet passageway, blower fan connect successively, described element 11 can be heating element heater or cooling module, described heating element heater is selected from electrical heating elements, or be water heating elements, steam heating elements, refrigerant heat element (as freon etc.), air or flue gas element, cooling module is selected from water cooling module, cold fluid cooling module (as ethylene glycol etc.), chiller refrigeration element (as freon etc.).
As shown in Figure 5, the process of this system sterilizing is as follows:
Air A enters inlet channel, and from 20 degree to 120 degree, be temperature ramp de, i.e. IT process, does not have outside energy to input in this process; Then enter element (11), air themperature, from 120 degree to 125 degree, is high-temperature heating process, i.e. HT process, and this process has outside energy E to input; Then air enters outlet passageway, is 25 degree from 125 degree of coolings, is temperature decline process and DT process, and because inlet channel and outlet passageway are disposed adjacent, therefore this process does not have outside energy to input equally.Represent in Fig. 5, bacterial virus etc., i.e. BV, gradually reduced by three processes above.
As can be seen from Figure 5, process of the present invention greatly reduces the input of energy.Conventional process is as realized same temperature changing process, and its energy requirement is far longer than this, and need input heat energy that temperature is raised to 125 degree from 20 degree, then input cold energy and be reduced to 25 degree by 125 degree, the former needs heat to input, and the latter needs cold to input.
If assuming that often spending variations in temperature is an energy unit, the present invention only has the input of 5 unit of heat energy, and process need 105 unit of heat energy inputs of routine, 100 cold energy unit inputs, totally 205 energy unit's inputs are 41 times of the present invention.
