Abstract
The utility model discloses an ultrasonic algae removing device comprising an ultrasonic generator, a cable and ultrasonic emitters, and is characterized in that the ultrasonic emitters are at least two, have double-frequency and are connected with the ultrasonic generator through the cable through adopting the parallel connection mode. The frequency of one of the ultrasonic emitters is low-frequency ultrasonic adopting different frequencies, which can respectively utilize the cavitation effect and the vibrating effect of the ultrasonic and has good effect of removing all algae in water, and the removing rate can reach more than 80%. The device has the advantages of simple installation and operation, no secondary pollution, low investment and operation cost, and no effect to aquatic plants and animals. A plurality of multiple-frequency ultrasonic emitters are arranged on the device according to different requirements, such as different types of algae and pollution degrees, and the algae removing effect is better.
Description
Technical field
The utility model relates to a kind of device that utilizes ultrasonic wave to suppress algal grown in the water body, is specifically related to a kind of ultrasonic algae-removing device.
Background technology
Along with the quickening of social process of industrialization, human in industrial and agricultural production and daily life, in water body, enter the pollutent of a large amount of nitrogenous, phosphorus, quickened the eutrophication process of lake, reservoir.At present, the body eutrophication problem that is on the rise has become global environment problem, and is especially serious in developing country.To the end of the year 2000, the lake of China almost is in eutrophy or heavy eutrophication state all, thereby causes algal bloom, forms wawter bloom, severe contamination water quality.
Mainly contain for the control of algae and removal technology and to change water law, chemical method, bed mud dredging and biological control etc.Changing water law is to dilute eutrophication water with cleaning water, is to pollute from the transfer of heavily contaminated district to the clear area, can not tackle the problem at its root, and misoperation also may cause the diffusion of pollution.Chemical method is to add a large amount of chemical agents in water body, because these medicaments do not have specificity, therefore to the other biological beyond the algae toxic action can take place also and in the bed mud accumulation and form chronic pollution, thereby causes widely and query.Bed mud dredging expense is high, and the bed mud of removing causes secondary pollution again, in addition, because dredging has destroyed the face of land ecosystem, makes that the eubiosis is broken, and may cause water quality not only not improve on the contrary and worsen.Biological control is the principle according to ecological food chain, introducing algophagous such as fish are waited the biomass that reduces algae in water body, this method on principle tool advantage, yet because the mechanism of algal grown is unclear fully as yet, influence factor is a lot of again in the water body, effect is still unstable in actual applications, needs engineering method as a supplement.
The application of ultrasonic wave in water treatment is a kind of novel environmental technology that development in recent years is got up.Patent of invention (publication number CN1422951A) discloses a kind of method of utilizing ultrasonic wave to suppress algal grown, it is characterized in that it is the ultrasonic wave of 1.7MHz that Xiang Shuizhong discharges frequency.This method has certain inhibition effect to some algae (blue-green algae) growth, but because frequency is single, effect limited (compare with the biomass of control group, after the ultrasonic wave effect, the blue-green algae biomass can reduce 50%, and is uncertain to other algae effects); In addition, the influence to aquatic animals and plants is studied under this high frequency.
Patent of invention (publication number CN1970459A) discloses a kind of reflection type ultrasonic device that is used for removing the water body algae.This device only utilizes hyperacoustic cavitation effect of reflection to reach the purpose of algae removal, and frequency is single, only the algae that contains air bag is had certain effect, and the present invention is not discussed the effect of algae removal.
The utility model content
The problem that the utility model is single at the frequency of above existence, effect is limited, having proposed multifrequency is the double-frequency ultrasound wave apparatus at least, utilizes hyperacoustic cavitation effect and vibration effect to reach purpose except that algae respectively.
A kind of ultrasonic algae-removing device comprises ultrasonic generator, cable and ultrasonic transmitter, it is characterized in that: described ultrasonic transmitter is at least 2, double frequency, adopts parallel way to be connected with ultrasonic generator through cable.
Described ultrasonic transmitter is the low frequency ultrasound wave launcher that frequency is 16～40KHz wherein, and another frequency is the ultrasonic transmitter of 40KHz～2.0MHz.
It is the low-frequency ultrasonic waves of 16～40KHz that algae in water body discharges frequency, and the high pressure, high strong shockwave, high speed acoustic streaming and the high shear force that utilize hyperacoustic cavitation to cause suppress and remove the algae that air bag is arranged in the water body.
It is the ultrasonic wave of 40KHz～2.0MHz that algae in water body discharges frequency, utilizes hyperacoustic mechanical effect, suppresses and remove the algae of no air bag in the water body.
The utlity model has following positively effect:
(1) by adopting the ultrasonic wave of different frequency, can utilize hyperacoustic cavitation effect and vibration effect respectively, algae all in the water body is all had removal effect preferably, clearance can reach more than 80%;
(2) installation and easy and simple to handle, non-secondary pollution;
(3) investment and running cost are low;
(4) aquatic animals and plants there is not influence.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
1. ultrasonic transmitter 4.40KHz～2.0MHz ultrasonic transmitter of ultrasonic generator 2. cables 3.16～40KHz.
Embodiment
A kind of ultrasonic algae-removing device as shown in Figure 1, it comprises ultrasonic generator 1, cable 2 and ultrasonic transmitter, described ultrasonic transmitter is at least 2, double frequency, adopts parallel way to be connected with ultrasonic generator through cable.Low frequency ultrasound wave launcher 3 that frequency is 16～40KHz wherein, another frequency is the ultrasonic transmitter 4 of 40KHz～2.0MHz.During use two ultrasonic transmitters are placed the water body that is polluted by algae, by ultrasonic generator 1 regulating frequency, the frequency of algae in water body release earlier is the low-frequency ultrasonic waves of 16～40KHz, utilize the high pressure that hyperacoustic cavitation causes, high strong shockwave, high speed acoustic streaming and high shear force, suppress and remove the algae that air bag is arranged in the water body.Algae in water body release frequency is the ultrasonic wave of 40KHz～2.0MHz again, utilizes hyperacoustic mechanical effect, suppresses and remove the algae of no air bag in the water body.
The utility model can be provided with many, multi-frequency ultrasonic transmitter according to the different needs such as dissimilar and pollution level of algae in the water body, make except that the algae effect better.
Claims (2)
1 one kinds of ultrasonic algae-removing devices comprise ultrasonic generator, cable and ultrasonic transmitter, it is characterized in that: described ultrasonic transmitter is at least 2, double frequency, adopts parallel way to be connected with ultrasonic generator through cable.
2 a kind of ultrasonic algae-removing devices according to claim 1 is characterized in that: described ultrasonic transmitter is the low frequency ultrasound wave launcher that frequency is 16～40KHz wherein, and another frequency is the ultrasonic transmitter of 40KHz～2.0MHz.
