When c, beginning atomization, whether proximity transducer detects liquid containing bottle in place.Liquid containing bottle liquid is transported to nebulizer by primer pump, and by liquid filter, liquid sensor, the situation such as strength of fluid, temperature is detected, and data feedback is arrived to controller, pressure transducer will be collected data feedback to controller 1, thereby determine the action of pump.
D, sensor according to the situation of biocide induction system, carrier gas transport process system to plasma generation module transmitted signal, plasma generation module, according to the signal of controller, can just send or negative electric charge formation voltage to nebulizer, voltage value can be set according to practical situation, also can carry out positive and negative alternately output.
E, ion generating electrodes export near nebulizer, and the high electric arc of generation stimulates atomization post, and the high-tension current of formation will dissociation disinfectant and air, destroy the molecular structure of disinfectant and air, form the sterilization ionic species group of ionic state.Meanwhile high-tension current, by like charges on sterilizing gas band, repels mutually, is abound with more rapidly sterilizing space.And by positive and negative adjustment, can more meet the demand of environment sterilizing.Complete faster the purification in space.
F, controller connection device sensor, can immediately monitoring ambient parameter, comprises sterilizing gas concentration, ambient temperature and humidity, in environment, whether the concentration content of hazardous gas, reach the parameters such as dangerous values, then make corresponding judgement by controller, provide processing execution signal.In environment especially complexity or generator apparatus are not placed on environment time, can reach by expansion outer sensor the effect of testing environment ad-hoc location.In the time that equipment is placed in sterilized environment, operator can carry out start and stop equipment by remote controller.
The present invention has following beneficial effect:
1, solved the formaldehyde fumigation time long, residual to human injury's problem;
2, solved hydrogen peroxide generator simultaneously, need to be to sterilized environment flow-disturbing, otherwise easily exist gas diffusion slowly, sterilizing dead angle, to ambient temperature, problem that humidity requirement is high;
3, eliminate the series of problems that corrosivity that conventional high-temperature dissociation (gasification hydrogen peroxide sterilization technology) technique brings and high concentrations of gas cause personal security, brought safer operating procedure by the dissociation technology of room temperature, normal pressure.
4, the equipment of realizing biological cleaning by this technology can accomplish, volume is little, and energy consumption is low, the advantage low to space requirement.
