A kind of sterilizing unit remaining best ultraviolet light output
Technical field
The present invention relates to a kind of bactericidal unit, in particular to a kind of chlorination equipment using ultraviolet disinfection.
Background technique
The DNA of the ultraviolet damage biological cell of ultraviolet germicidal lamp transmitting 253.7nm wavelength in the prior art, reaches and kills
The purpose of bacterium disinfection.Currently, one is traditional tube straight pipe types, by hot cathode there are three types of ultraviolet germicidal lamps in the market
The electron excitation mercury atom of launching electronics, movement generates ultraviolet radiation, and another kind is electromagnetic induction type, by electromagnetic field of high frequency
Mercury atom is motivated to generate ultraviolet radiation, also one is microwave excitation types, generate by microwave electromagnetic field excitation mercury atom purple
UV radiation, three of the above form bactericidal lamp are generated by excitation mercury atom, these three are different be only obtain it is metastable
The means of the mercury atom of state are different, the above is routinely used the fluorescent tube of liquid mercury tube wall temperature close to 40 DEG C when
Hou Caineng obtains strongest ultraviolet light, and corresponding environment temperature is about 20 DEG C to 26 DEG C, and uitraviolet intensity is stronger, and bactericidal effect is got over
It is good, and the excessively high and too low decline that can all cause uitraviolet intensity of temperature, the intensity of every degree decline about 0.8%, therefore work as tube wall temperature
Ultraviolet light will be greatly lowered 25%~30% after spending lower than 10 DEG C or higher than 70 DEG C, winter and inflammation of the above bactericidal lamp in severe cold
The summer effect of heat is all very poor, it appears that lamp is bright but actual strength only has the 60%~70% of ultraviolet light maximum intensity.
Technical staff in traditional technology field thinks, in order to guarantee the light efficiency of ultraviolet germicidal lamp, needs to guarantee tube wall
Temperature reach 40 DEG C~50 DEG C, but in the faster medium that radiates, such as in flowing water or the low temperature waste gas in winter is net
In change processing, tube wall temperature is substantially consistent with environment temperature, and at low ambient temperatures, tube wall temperature is no Faville
It holds between 40 DEG C~50 DEG C, therefore, at low ambient temperatures, the light efficiency reduction of ultraviolet germicidal lamp is inevitable.It is existing
Have in technology, does not solve to still ensure that the technological means that ultraviolet germicidal lamp is in good light efficiency at low ambient temperatures.
Summary of the invention
For the defects in the prior art, it is an object of the invention to overcome the deficiencies in the prior art described above place, mentions
For a kind of sterilizing unit for remaining best ultraviolet light output, it is ensured that in the case where tube wall temperature change, can also make
Amalgam maintains optimal operating temperature, exports strongest ultraviolet light to obtain optimal bactericidal effect.
The object of the present invention is achieved like this: a kind of sterilizing unit remaining best ultraviolet light output, including is in
The quartz ampoule of enclosed construction is provided with exhaust pipe of the opening towards quartzy tube cavity, the quartz ampoule peripheral hardware on the quartz ampoule

In vivo, the tail portion of the exhaust pipe is equipped with tail pipe, and amalgam is equipped in the tail pipe, and the tail pipe outer wall is equipped with ptc heating sheet.
Studied for a long period of time discovery, and when amalgam material is applied in fluorescent tube, absorbing and releasing mercury atom is one dynamic
Process, this dynamic process is related with the temperature of amalgam itself, and little with the tube wall temperature degree of association, as long as part guarantees amalgam
The highest light efficiency of ultraviolet germicidal lamp can be realized in the temperature of position.This creative discovery, so that not needing to keep
Tube wall temperature, that is, the high photosynthetic efficiency for being able to achieve ultraviolet light are possibly realized.When the invention works, in radio-frequency generator and calutron
High-frequency oscillating circuits is formed between induction coil, electromagnetic induction occurs for induction coil and magnet ring effect, so that generating electricity in quartz ampoule
Magnetic field, the mercury atom in quartz ampoule be activated to launch the ultraviolet light of 253.7nm, meanwhile, it is selected according to seasonal variations and amalgam
Type adjusts the on-off of ptc heating sheet, makes that amalgam reaches optimal operating temperature and constant temperature is kept throughout the year, realizes uitraviolet intensity
It does not change because of the transformation in season, which is directly projected to outside quartz ampoule, and action of ultraviolet radiation is in the DNA of biological cell
Variation is brought it about, the existence of cell is destroyed, reaches optimal bactericidal effect, the present invention replaces liquid mercury with amalgam, in fluorescent tube
Mercury vapour pressure depend no longer on tube wall temperature and controlled by the temperature of amalgam location point, improve exhaust pipe in mercury vapour pressure can
Control property, prolongs the service life, and improves the feature of environmental protection, is using ptc heating sheet or ptc heating sheet and temperature according to the determination of amalgam type selecting
Device is controlled, guarantees that the long-term constant temperature of amalgam location point, the exportable best ultraviolet light of fluorescent tube obtain strongest bactericidal effect, breaches this
The inertial thinking of field technical staff solves and wants always to solve and unsolved technical problem in the art.Device master
Be used in the exhaust gas photodissociation purified treatment and the dirty water decontamination handles of factory, can in subzero 20 DEG C of low temperature environment normal work
Make.
As a further improvement of the present invention, the amalgam is Low temp amalgam or medium temperature amalgam, the ptc heating sheet and high
Frequency generator connection is powered in cold snap to ptc heating sheet, and the program can make amalgam location point keep constant temperature, and raising is killed
Bacterium effect.
As a further improvement of the present invention, the amalgam is high-temperature amalgam, is additionally provided with temperature controller on the tail pipe outer wall,
The temperature controller output end is connect with ptc heating sheet, and the temperature controller is electrically connected with radio-frequency generator respectively with ptc heating sheet
