Embodiment 1

[0048] figure 1 It is a schematic diagram of the structure of the air-conditioned train plasma air disinfection purifier; figure 2 It is a structural schematic diagram of another embodiment of the present invention; image 3 It is a schematic diagram of the three-dimensional structure of the plasma reactor of the present invention.

[0049] Such as figure 1 As shown, the air-conditioned train plasma air disinfection purifier includes a plasma reactor 1, a pulse power supply 2, a fan assembly 3, an air inlet 5, an air outlet 6 and a casing, and the air inlet 5 is provided with a primary air filter 9, and the plasma The bulk reactor 1 and the fan assembly 3 are arranged in the air flow. The plasma reactor 1 is provided with positive electrodes 101 made of several nickel-chromium metal wires or nickel-chromium metal strips arranged in parallel at equal distances in the same plane, and the positive electrodes 101 are placed in two adjacent negative electrodes 102 The middle p...

Embodiment 2

[0065] See figure 1 In this embodiment, a surface cooler 23 , a heater 24 , and a humidifier 25 are sequentially arranged between the plasma reactor 1 and the fan assembly 3 . In addition, a control device 4 is provided. A single-chip microcomputer containing programming is arranged in the control device 4. Each function output terminal of the control device 4 is respectively connected to the pulse power supply 2 of the plasma reactor, the fan assembly 3, the surface cooler 23, and the heating device through the control wire 27. The power input terminals of the device 24 and the humidifier 25 are electrically connected correspondingly. This arrangement has the effect of air conditioner concurrently for loading onto the present invention on the top of the train carriage without air conditioner. Control device 4 can set start-up time, compartment temperature, humidity.

Embodiment 3

[0067] image 3 As shown, when the disinfection and purification space is large, and the number of the anti-microdischarge conductive rails 103 installed in the plasma reactor exceeds 5, the two ends of the microdischarge conductive rails 103 are orthogonally arranged on the four sides of the reactor. A positive electrode metal support 104 is fixed and electrically connected; each positive electrode metal support 104 is provided with an insulating connector 105 at the upper and lower ends of the corresponding mounting hole of the reactor shell 108, and is fixed on the reactor shell 108. An insulating connector fixing bolt 106 is provided to tightly fix the insulating connector 105 . This design reduces the amount of insulating connectors 105, and the structure is compact. The positive electrode metal support 104 designed by the present invention has a diameter of 4.0 mm, and the outer edge of the positive electrode metal support 104 is provided with a fixed ring 107 for preve...

Abstract

The invention relates to a plasma air sterilizing and purifying device for an air-conditioned train, which comprises a plasma reactor, a pulse power source, a fan component, an air inlet, an air outlet and a shell and is characterized in that a positive electrode which is formed by arranging a plurality of nickel-chromium metal wires or nickel-chromium metal bands in the same plane at equal intervals in parallel is arranged in the plasma reactor; the positive electrode is arranged in the middle position of two adjacent negative electrodes; the two ends of the positive electrode are fixed in a groove or a convex part corresponding to a conductor rail for preventing micro-discharge; each negative electrode is made of an aluminum plate the surface of which is oxidized, and nano-TiO2 is respectively laid on the two surfaces of each negative electrode; and a pulse transformer and a pulse generator are arranged in the pulse power source and are arranged according to a single-ended flyback inverter. The device of the invention is arranged at the return air inlet or the air outlet of an air conditioner in a carriage, and the existing facilities of the air-conditioned train do not need to be changed. The device of the invention is the optimal combination of plasma and TiO2, has high dynamic sterilization and purification efficiency of a passenger train, and has the advantages of energy saving, good reliability, long working life, simple structure and convenient installation.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, in particular to a plasma air disinfection purifier for air-conditioned trains. Background technique: [0002] At present, the air-conditioning units used in my country's railway trains use fresh air filtered outside the train to account for one-third, and circulating return air inside the train accounts for two-thirds. As we all know: large fresh air volume, high energy consumption; small fresh air volume, increased air pollution inside the car. Air-conditioned passenger trains travel north and south, especially high-speed trains, which are fast, highly sealed, and there are many passengers in the compartments, so inhalable particles and toxic and harmful gases will accumulate more and more. It is particularly emphasized that in recent years, SARS, bird flu and the current H1N1 influenza have caused a large-scale global infection. The latest epidemic bulletin issued b...
