The specific embodiment
Provide the present invention's one preferred embodiment below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
Extremely shown in Figure 4 like Fig. 1; The on-Line Monitor Device that is used for the uv radiation dose of ultra violet sterilizer of the present invention comprises: one comprises the lamp assembly of several ultraviolet lamp tubes 1, a motor and an electric machine support 3, one connecting rods 4; Wherein, The lamp assembly is provided with the tube stand 2 that is used for fixing ultraviolet lamp tube 1, and connecting rod 4 one ends link to each other with the mandrel of motor, its other end be connected with one carry out information gathering and monitoring ultraviolet probe 5.Every ultraviolet lamp tube 1 is covered with a quartz socket tube.Electric machine support 3 is fixed on a side of tube stand 2.Under the driving of motor, mandrel drivening rod 4 rotations through motor, through the signal and the power control system that are electrically connected with ultraviolet probe 5, the control ultraviolet is popped one's head in and 5 is carried out information gathering, the on-line monitoring of the uv radiation dose during the realization ultraviolet disinfection.Connecting rod 4 can adopt any one in a straight-bar, a curved bar and the pole, can also be a kind of multistage connecting rod certainly.When connecting rod 4 adopts multistage connecting rod, micromachine can be set between the continuous connecting rod realize the interlock control between multistage connecting rod.Wherein, the microcontroller of above-mentioned micromachine part and signal and power control system that ultraviolet is popped one's head in partly are prior art, do not give unnecessary details at this.
As depicted in figs. 1 and 2; When ultraviolet lamp tube 1 is placed for horizontal; The plane of movement (or rotational plane) at connecting rod 4 place should keep and the ultraviolet lamp tube 1 place angled α in plane, such as can being that present embodiment is 20 degree from any angle between 0 degree to 90 degree.And connecting rod 4 can rotate to 180 degree from 0 degree in the rotational plane at its place.In the testing process; Do the rotation of certain angle through Electric Machine Control connecting rod 4; Keep ultraviolet to pop one's head in plane, 5 place in whole motion process; Keep the plane parallel that belongs to all ultraviolet lamp tubes 1 of lamp assembly or become certain α angle, ultraviolet probe 5 belongs to planar distance also from low to high with ultraviolet lamp tube 1, becomes cyclically-varying more from high to low; And then measure the ultraviolet radiation intensity at ultraviolet lamp tube 1 different distance place, so just can carry out the on-line monitoring of the uv radiation dose of ultra violet sterilizer of the present invention.
Below with shown in Fig. 1 to Fig. 4, it is example that the anglec of rotation of connecting rod 4 is respectively the situation of 30 degree and 90 when spending, and further specifies the test and the analytic process of this device:
Like Fig. 3 and shown in Figure 4; When the plane of movement at connecting rod 4 place and plane, ultraviolet lamp tube 1 place at an angle; Such as, as shown in Figure 2 20 when spending, and spends with 90 if the angle of connecting rod 4 rotations this moment is respectively 30 degree; Suppose the long L of being of bar of connecting rod 4; Calculate the vertical dimension of ultraviolet probe 5 in the plane of movement at connecting rod 4 places earlier, again this vertical dimension is projected in the horizontal plane at ultraviolet lamp tube 1 place, collude a burst law computing through twice; Project to the planar of the 3rd ultraviolet lamp tube place so obtain ultraviolet probe 5, and the ultraviolet probe projects to the planar apart from d2=L*sin90 ° of * tan20 ° of the 3rd ultraviolet lamp tube place apart from d1=L*sin30 ° of * tan20 °.
Suppose real work constantly the unit distance of contaminated water body be A to the ultraviolet radiation actual absorption, the quartz socket tube that has a dirt is a to the actual absorption value of ultraviolet radiation, and pure water is A to the initial absorption value of ultraviolet radiation
0, the initial absorption value of clean quartz socket tube ultraviolet radiation is a
0Therefore; In the real work moment, there is the quartz socket tube of dirt in the water quality of promptly polluting with certain, compares original state; Be under pure water and the clean quartz ampoule, then obtain ultraviolet probe 5 respectively and rotate to directly over the 3rd tubes and the variation delta D of the measured value directly over second tubes
3With Δ D
2, be (A
0-A*L*sin30 ° * tan20 °-)+(a
0-a) with (A
0-A*L*sin90 ° * tan20 °)+(a
0-a).
Compare Δ D
3With Δ D
2Can know:
If Δ D
3=Δ D
2=0, show that then water quality is pure water, the quartz ampoule clean level is 100%;
If Δ D
3=Δ D
2＞0, show that then water is pure water and quartzy clean level＜100%;
If Δ D
2＞Δ D
3＞0 and Δ D
3/ Δ D
2=(A
0-A*L*sin30 ° * tan20 °)/(A
0-A*L*sin90 ° * tan20 °), show that then there is pollution (increase of unit distance uv absorption) in water, the quartz ampoule clean level is 100%;
If Δ D
3＞Δ D
2＞0 and Δ D
3/ Δ D
2≠ (A
0-A*L*sin30 ° * tan20 °)/(A
0-A*L*sin90 ° * tan20 °), show that then water exist to pollute (increases of unit distance uv absorption), quartz ampoule clean level＜100%, thus the while judge the pollution level of water quality and quartz ampoule accurately.
Above-mentioned about d1 and d2, and the ultraviolet probe projects to the variation delta D of the planar range determination value at ultraviolet lamp tube place
3, Δ D
2Arithmetic section, all be the content that those skilled in the art can be appreciated that and understand fully according to existing known operational formula, therefore repeat no more at this.
On-Line Monitor Device of the present invention; On the one hand with the ultraviolet probe of conventional fixed on the slide unit that slides along the fluorescent tube direction; Design one instead and be positioned on the tube stand in the outside, whole lamp assembly middle part; Make the ultraviolet probe when not working, also can be on the water surface, therefore daily cleaning and maintain and replace are all very convenient.On the other hand; Device of the present invention can also adopt the rotary design of multistage connecting rod; Only just can accomplish radiation dose monitoring to the whole fluorescent tubes of whole lamp assembly with a ultraviolet probe; Compare the existing design of need the ultraviolet identical popping one's head in and accomplishing, make the cost of monitoring reduce greatly with the fluorescent tube number.In addition; The present invention can to the test of the uv radiation dose of the position of fluorescent tube different distance; The influence for actual uv radiation dose of fluorescent tube fouling and water quality light transmission index variation is made a distinction, make whole test system can be more accurately to ultraviolet output control.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited appended claims.
