Problems solved by technology

Amalgam is an alloy of mercury and other metals. It is solid at room temperature and is not easy to diffuse. There is basically no mercury vapor generated. When working in a high-temperature environment of ℃, the 254nm ultraviolet radiation efficiency is still high, thereby improving the sterilization effect and saving energy

Embodiment 1

[0015] Figure 1 shows a double-ended amalgam-like ultraviolet germicidal lamp with a power of 75W and a current of 0.425A, including glass tube 1, lamp cap 2, filament 3, main amalgam 4, auxiliary amalgam 5, and molybdenum sheet 6 , Molybdenum rod 7, wick 8, glass tube 1 is filled with inert gas. As a double-ended amalgam-like ultraviolet germicidal lamp, the glass tube 1 is a straight tube with a diameter of 15mm and a length of 1554mm; The main amalgam 4 is arranged in the middle of the glass tube 1 . The main amalgam 4 of the lamp is made of N amalgam, and its working environment temperature is 50° C., and the auxiliary amalgam 5 is welded on the molybdenum rod 7 which is 5 mm away from the filament 3 . The glass tube 1 of the lamp is made of an ozone-free quartz glass tube of the same material, and does not generate ozone during use.

Embodiment 2

[0017] The main amalgam 4 of this lamp adopts R amalgam, and its working environment temperature is 25°C, and no auxiliary amalgam 5 is provided. All the other are identical with embodiment 1.

Embodiment 3

[0019] The glass tube 1 of the lamp is made of high ozone quartz glass tube of the same material, which has a high ozone output rate. All the other are identical with embodiment 1.

Abstract

The invention is a UV sterilization lamp of substituting amalgam for liquid Hg, comprising glass tube, lamp adapter, filament, main amalgam, auxiliary amalgam, Mo plate, Mo rod and lamp core, where the glass tube is filled with inert gas. And according to needs, it can be made into two- end, single-end, and self-ballasting amalgam UV sterilization lamps. And the two-end and self-ballasting ones can be made into H shape, U shape annular shape, 2H shape, 2U, spiral shape and the other shapes. And it selects different types of amalgams as main amalgams, able to be made into amalgam UV sterilization lamps applied to different environmental temperatures and having high radiation efficiencies. And it can be made into large-power, small-calibe UV sterilization lamps. And it can radiate UVs with 254 nm as the principal wavelength at different environmental temperatures.

Description

technical field [0001] The invention belongs to an ultraviolet germicidal lamp, in particular to an ultraviolet germicidal lamp which replaces liquid mercury with amalgam, has no pollution to the environment, and can radiate ultraviolet rays at different ambient temperatures with high efficiency. It is used for air, object surfaces, water or Sterilization of other liquids. Background technique [0002] The ultraviolet germicidal lamps currently used are low-pressure mercury vapor arc discharge lamps, and the lamp tubes are filled with liquid mercury during manufacture. At normal temperature, there are both mercury vapor and liquid mercury in the lamp tube. Mercury is a metal that is harmful to humans and the environment. Its melting point is -39°C. It is liquid at room temperature and easily diffuses and evaporates into mercury vapor. During the production process of the lamp tube, it is very easy to cause harm to the workers and the surrounding environment; when the lamp ...
