Example 4
Referring to fig. 1-2, on the basis of embodiments 1-3, the following technical features (the following specific arrangements are made for the structure and dimensions of the cancellation device) are added to this embodiment: the height of the eliminating equipment is 1600mm, the length is 1500-1800mm, the upper width is 700mm, and the lower width is 400mm.
The shell 2 is composed of cold-rolled steel plates, and the structural parts of the air disinfection and purification unit and the primary filter screen 6 are composed of stainless steel 304.
The single equipment is designed into two air quantity modes, 1000m3/h and 600m3/h air quantity, the air supply fan 10 can adjust the air quantity, a controller is arranged outside the elimination equipment, and the controller is connected with the controller through wires or wirelessly; the controller comprises a central controller, a data analysis module, a data storage module and a communication module, wherein the data analysis module, the data storage module and the wireless communication module are respectively connected with the central controller; the data storage module is utilized to effectively archive the time and duration of each use, so that the next calling and checking are facilitated, and the air quantity and the switch can be controlled by the controller.
When no person is in the process of disinfection treatment, a 1000m3/h mode can be adopted, and the indoor air circulation times are maximized; when the human-machine coexists, the mode of 600m3/h is adopted, and the indoor air is in a relatively stable state as much as possible while the indoor air is disinfected and purified. The number of air purification cycles of the room with the air quantity of 19 and 12 times for the layer height of 40 square meters and 2.6 meters is respectively.
Principle of microbial inactivation and pathogen nucleic acid elimination: the high voltage electric field is capable of releasing the plasma. The plasma is a conductive fluid which is composed of electrons, ions, free radicals, excited state particles and the like, is electrically neutral as a whole, has complex and various composition components and active properties, and besides high-energy particles, ultraviolet rays and high-energy electric fields, the plasma also contains a plurality of active particles which are excited or not excited. When these active particles come into contact with microorganisms, a complex series of biochemical reactions and physical processes occur with the biofilm. From a macroscopic point of view, the sterilization process of the atmospheric pressure low-temperature plasma is actually a process that active components (such as positive and negative ions, active groups, charged particles, electric fields, ultraviolet rays, etc.) generated by the plasma interact with biological macromolecular substances (such as proteins, DNA, lipids, etc.), and cause changes of cell components (such as cell walls, cell membranes, cytoplasm, etc.), thereby causing cell death. The plasma active component can inactivate and denature biomacromolecules in a short time or can change the oxidation stress level in cells, thereby achieving the aim of microorganism inactivation.
When plasma acts on microorganisms, different tissues of the microorganisms can make different biological responses, when active substances generated by the plasma act on cell membranes, lipid on the cell membranes is peroxidized, the cell membrane potential is changed, the cell membrane permeability is increased, more plasma active ingredients outside the environment are caused to enter the inside of the cells, the cell contents are leaked, at the moment, the cell membrane form is collapsed or defective, normal physiological functions of the cells are disturbed, and the cell membranes are broken, so that apoptosis and even death are caused. When the active components of the ion act on the cells, oxidation damage is carried out on biomacromolecule substances such as protein, nucleic acid, lipid and the like, so that complex biochemical reactions such as denaturation of protein structure, DNA oxidative degradation, lipid peroxidation and the like are caused, and further important influence is caused on the physiological functions of biological tissues. The microorganisms subjected to plasma treatment are not obviously damaged in morphology, but have reduced metabolic capacity, slow growth or stop growth, and the activity of metabolic enzymes is destroyed, so that the microorganisms are finally killed. Wherein plasma-induced lipid peroxidation of cells may be a major factor in causing the cells to be in a sublethal state.
The above description of embodiments is only for the understanding of the present invention. It should be noted that it will be apparent to those skilled in the art that modifications can be made to the present invention without departing from the principles of the invention, and such modifications will fall within the scope of the claims.
