Description of the drawings
Its example embodiment is described in detail by referring to accompanying drawing, above and other feature of the invention and advantage will become It is more obvious.
Fig. 1 is the schematic diagram of solar film battery reactive tank of the present invention.
Wherein, the reference numerals are as follows:
1- supersonic generators;2- oscillator for ultrasonic transducer;3- reactive tank outer walls.
Specific implementation mode
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes Formula is implemented, and is not understood as limited to embodiment set forth herein;On the contrary, thesing embodiments are provided so that the present invention will Fully and completely, and by the design of example embodiment comprehensively it is communicated to those skilled in the art.It is identical attached in figure Icon note indicates same or similar structure, thus will omit their detailed description.
Referring to Fig. 1, the reactive tank of the solar film battery of the embodiment of the present invention, including supersonic generator 1, ultrasonic wave Energy converter oscillator 2, oscillator for ultrasonic transducer 2 are set to reactive tank outer wall 3.
Oscillator for ultrasonic transducer 2 can be multiple, be centrosymmetric and be set on reactive tank outer wall 3.Ultrasonic wave transducer Device oscillator 2 is uniformly distributed on the maximum side wall of reactive tank bulk area, can be only arranged on unilateral wall.Due to wet method plated film work Skill groove body inner space is narrow, and oscillator is arranged in groove body side wall, it is sufficient to fully be cleaned to four wall of groove body.It is preferred that ultrasonic wave 2 power of energy converter oscillator is identical, and multiple oscillators 2 are distributed in identical spacing in outer wall or embedded groove body.
Supersonic generator 1 may be located remotely from groove body, ensure operational safety.Supersonic generator 1 can pass through high frequency electric source Line connects energy converter oscillator 2, can carry out power, time-controllable to it.The quantity of oscillator 2 can be designed so that reactive tank inner wall All in the sphere of action of oscillator.For example, supersonic generator 1 can be in 20~130HZ, oscillator power 60 with frequency ~100W, each oscillator effect effective range are shaken in 40~80mm*40~80mm*40~80mm according to the area of outer wall 3 arrangement Son 2, makes groove body inner wall be in the sphere of action of oscillator 2.Can also be selected according to cleaning experiment effect different frequencies into Row cleaning, frequency size directly affect the cleaning speed of equipment.
Reaction groove body material can there are many selections, such as austenitic stainless steel, titanium plate, HTPVC (fire resistant resin) material. Nickel and high trade mark Cr-Ni-Mo austenitic stainless steels containing molybdenum, have nonmagnetic, and high temperature resistant, chemicals-resistant, acid and alkali-resistance etc. are outstanding Characteristic can use the solution of the reactions such as high temperature, soda acid as, reliable and stable.It, can be with inner wall increasing if selecting general stainless steel alloy plate Add one layer of titanium coating or Titanium board.Titanium board has very strong acid-fast alkali-proof performance.HTPVC has outstanding weatherability, very Good corrosion resistance and chemical resistance.With extraordinary hot property, can be used continuously under the conditions of 80 DEG C of temperature highest.Slot External wall is also provided with reinforcing rib.
It (is usually the diluted acid that effective concentration is no more than 5% at room temperature, diluted acid that dilute acid soln is added when cleaning, in reactive tank Liquid level is not less than the 95% of groove body height).Concentration is too low, and chemical reaction is slower, and scavenging period is long.Concentration is too high, chemical hazard Property is higher.Diluted acid is usually dilute hydrochloric acid, dilute sulfuric acid or dust technology.Dilute acid soln reacts mildly, securely and reliably at room temperature.Room temperature, The use for avoiding heater, reduces plant maintenance operation cost, and process is safer controllable.Reactive tank impregnates 3 through dilute acid soln After~5min, supersonic generator is opened, carries out ultrasonic cleaning.Finally, waste liquid after discharge cleaning.
The present invention Cleaning principle be:Dilute hydrochloric acid solution is filled it up in reactive tank, by energy converter by power ultrasonic source sound Mechanical oscillation can be converted into, by reacting groove groove wall by dilute hydrochloric acid solution in Ultrasonic Radiation to groove body.Due to by ultrasonic wave Radiation, enable the microbubble in tank liquid kept under the action of sound wave vibration.Destroy dirt and cleaning parts surface Absorption, causes the fatigue rupture of crud layer and is refuted from the surface of groove body is cleaned in the vibration of gas type bubbles.Make vulcanization Cadmium Pollutants On The Chinese is reacted by dispersion, emulsification, stripping cell wall and with dilute hydrochloric acid, reaches groove body cleaning purpose.
Energy converter is combined by the present invention with reaction groove body, dismantlement work when groove body being avoided to clean, can direct line it is enterprising Row makes reactive tank cleaning performance be multiplied by coordinating with dilute hydrochloric acid chemical solution.Scavenging period can shorten half with On.
Embodiment 1
Reactive tank material is acid and alkali-resistance, high intensity, heat safe 304 stainless steel plate (nickel and the high trade mark Cr-Ni- containing molybdenum Mo austenitic stainless steels), cell wall increases plate muscle mechanical plate rib and reinforces groove body stability outside.Size is:1800*1150* 100mm, space 60mm, cell wall thickness 20mm in notch.
If being 60W with each oscillator power, energy converter oscillator, apart from an oscillator calculating is installed, needs element number with 80mm For 690 oscillators, (element number of the big side setting of two areas calculates as follows amount:(1800/80*1150/80) * 2=644; The element number of the small side setting of two areas calculates as follows:1800/80*100/80) * 2=46), 690*60=41400W.
If being 75W with each oscillator power, energy converter oscillator is installed an oscillator with 100mm distances and is calculated, and oscillator is needed Quantity is that (element number of the big side setting of two areas calculates as follows 468 oscillators:(1800/100*1150/100) * 2= 432;The element number of the small side setting of two areas calculates as follows:(1800/100*100/100) * 2=36 oscillators), total work Rate about 468*75=35100W.
Using a concentration of 5% dilute hydrochloric acid as cleaning solution.Cleaning solution is added in reactive tank, liquid level is not less than 95%.Impregnate 3 ~5min makes cell wall cadmium sulfide react with hydrochloric acid.Supersonic generator is opened, ultrasonic cleaning is carried out, it is anti-to accelerate chemistry Speed is answered, while cadmium sulfide particle on groove body being made to fall off.Finally, waste liquid is handled after discharge cleaning.
The cleaning method of the present invention can select different supersonic generators according to groove body size, shape, pass through It controls its position distribution, frequency, power, size, opening time etc. and reaches optimal cleaning effect.Such as spherical reaction is held Device, cylindrical groove body, this kind of groove body half bore is smaller, and cleaning is inconvenient, in conjunction with method for suppersonic cleaning, can be greatly improved clear Wash efficiency.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe It knows those skilled in the art and makes various corresponding change and deformations, but these corresponding changes and change in accordance with the present invention Shape should all belong to the protection domain of appended claims of the invention.
