Embodiment Construction
[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0025] like figure 1 As shown, a medium-pressure discharge lamp includes a lamp tube 1, a cathode 2 and an anode 3 arranged in the lamp tube 1, and also includes two lamp caps 4 and two tungsten rods 5, and the cathode 2 passes through one of the tungsten rods. The rod 5 is electrically connected to one of the lamp caps 4, the anode 3 is electrically connected to the other lamp cap 4 through another tungsten rod 5, the cathode 2 is connected to the lamp cap 4, and the anode 3 is connected to the lamp cap 4. There are respectively transition joints 7 between them, the tungsten rod 5 is fixed to both ends of the lamp tube 1 through the transition joint 7, and o...

Abstract
The invention provides a medium-voltage discharge lamp and a manufacturing process thereof, and a water treatment disinfection method. The lamp tube of the medium-voltage discharge lamp is made of magnesium fluoride of which the VUV (vacuum ultraviolet) transmittance is much higher than that of the quartz or glass material used by common bulbs. The lower the band of ultraviolet is, the stronger the lethality to biological cells is. Because of the unique VUV band transmittance of magnesium fluoride, the medium-voltage discharge lamp of the invention can emit VUV with enough energy, and has good performance of deep disinfection or rapid disinfection. Mercury ultraviolet output bulbs are no longer needed, and the impact on the environment is reduced. In addition, a mixture of deuterium gas and argon gas is used, and ultraviolet output can be produced in the ionization excitation and reduction process of deuterium gas. As great heat is produced instantly in the excitation and reduction process of deuterium gas, the lamp should not be filled with too much deuterium gas, and the ratio of deuterium gas to argon gas can be 1:16.
Description
technical field [0001] The invention relates to a medium-pressure discharge lamp, a manufacturing process thereof, and a water treatment and sterilization method. Background technique [0002] Existing germicidal lamps often include small amounts of mercury, a heavy metal that poses environmental disposal hazards. In existing operations, personal protective equipment and lengthy handling processes are used to mitigate operating conditions that are hazardous to personnel during assembly and handling of these lamps. However, this kind of control is still difficult to avoid environmental hazards, and there is also a risk of mercury leakage during use. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the prior art, the present invention provides a medium-pressure discharge lamp and its manufacturing process and water treatment and sterilization method. The medium-pressure discharge lamp...
