Technical field
The utility model belongs to purification of air process field, is specifically related to a kind of microparticle coagulation type gravitational precipitator.
Background technology
Purification of air is widely used in the fields such as Aero-Space, microelectronics, semiconductor, medicine, food, chemical industry, health care, current gravitational precipitator equipment is greater than 1 μm of particle to particle diameter very high filter efficiency, and to being less than the particle filtering poor effect of 1 μm.The dust pollution thing removing particle diameter less needs the like products such as expensive high efficiency particulate air filter HEPA usually, filter after a certain period of use time (adsorption capacity drops to and cannot meet processing requirements) needs is changed, and the progression of multistage filtering is more, energy consumption is also larger, therefore, not only filter efficiency is lower, and does not meet the social development requirement of energy-saving and emission-reduction.
Utility model content
The purpose of this utility model be to provide a kind of can the microparticle coagulation type gravitational precipitator of high-efficient purification different-grain diameter particle.
For achieving the above object, the utility model have employed following technical scheme:
Comprise gravitational dust collection unit and microparticle cohesion unit, described microparticle cohesion unit comprises chamber and is arranged at the supersonic generator of chamber sidewall outer surface, the ultrasonic wave sidewall of chamber offered for producing for described supersonic generator enters the through hole in chamber, described gravitational dust collection unit comprises air inlet, air outlet, current-sharing unit and gravity settling chamber, air inlet, current-sharing unit and chamber are communicated with successively, one end of gravity settling chamber and chamber, the other end is communicated with air outlet.
The lower end of described gravity settling chamber is provided with flue-dust retainer.
Described current-sharing unit adopts homogenizing plate.

3.
The beneficial effects of the utility model are embodied in:
The utility model, before gravity settling chamber, utilizes ultrasonic coagulation mode to increase dust granules particle diameter, increased efficiency, realizes using single deduster to reach the object of the multiple particle diameter dust granules of high-efficient purification dust air-flow.In addition, compare existing deduster, the utility model structure is more simple, and operation and maintenance is more convenient.
The utility model adopts chamber as process space, enter by air inlet, dust-contained airflow after homogenizing plate current balance function carries out ultrasonic wave process in the chamber, ultrasonic wave is utilized to reach the effect of particle aggregation, finally efficiently can remove finely ground particles, ensure that gravitational precipitator has higher efficiency of dust collection to each particle size range.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1 is chamber, 2 is supersonic generator, and 3 is through hole, and 4 is air inlet, and 5 is homogenizing plate, and 6 is gravity settling chamber, and 7 is air outlet, and 8 is flue-dust retainer.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is elaborated.
See Fig. 1, microparticle coagulation type gravitational precipitator described in the utility model comprises microparticle cohesion unit and gravitational dust collection unit.Described microparticle cohesion unit comprises supersonic generator 2 and chamber 1.Described gravitational dust collection unit comprises air inlet 4, homogenizing plate 5, gravity settling chamber 6, air outlet 7 and flue-dust retainer 8.Supersonic generator 2 is arranged on chamber 1 wall place, and its ultrasonic wave produced enters chamber 1 through the through hole 3 being opened in chamber 1 wall.Air inlet 4, homogenizing plate 5, chamber 1, gravity settling chamber 6 and air outlet 7 are communicated with from left to right successively, flue-dust retainer 8 is connected to gravity settling chamber 6 lower end, homogenizing plate 5 enters chamber 1 after making the air current composition of the dust-contained airflow entered from air inlet 4 be assigned as uniform and stable air-flow, ensures that the ultrasonic wave that supersonic generator 2 sends fully can irradiate air-flow.Flue-dust retainer 8 dust collected by gravitational settling is stored in the inside, cleaned out by flue-dust retainer 8 when reaching certain capacity
The processing method of above-mentioned microparticle coagulation type gravitational precipitator, comprises the following steps:
1) start for generation of hyperacoustic supersonic generator 2, and entered in chamber 1 by the ultrasonic wave that through hole 3 makes described supersonic generator produce.
3) dust air-flow enters from air inlet 4, after homogenizing plate 5 current balance function, dust uniform stream flow in chamber 1, the time of staying of air-flow in chamber 1 is at least 1 second, and (time of staying refers to that pending gas is from entering chamber to the time of flowing out chamber, namely pending gas accepts the time of ultrasonic wave process in chamber, hyperacoustic direction is vertical with pending gas flow, and homogenizing plate can be used as one of means controlling the time of staying).When chamber 1 is by dust air-flow, under ul-trasonic irradiation, dust granules starts to vibrate together with gas medium, and have different Relative Vibration speed because dust granules varies in size, particle will collide bonding mutually, volume and quality all can become large, then ultrasonic vibration campaign can not be followed greatly because particle becomes, but random motion, continue collision, bonding becomes large, reaches flocculating result.
3) through the dust air-flow of particle aggregation after gravity settling chamber 6 subsiding and purifying, discharged by air outlet 7.
Experimental example
Adopt containing dust air as trier, filter is same gravitational precipitator, and metrical instrument is dust particle measuring instrument, and humidity is not measured.Metrical instrument is in gravitational precipitator rear end, and air sampling data after collection sedimentation, compare with non-sedimentation sampled data.Supersonic generator power output is 45W/cm
3, frequency is 24.1KHz.
Result shows, and ultrasonic wave process approximately reduces 20 ~ 30% than not applying the number of particles of ultrasonic wave process by gravitational precipitator.
Experiment proves, gravitational precipitator filter effect described in the utility model is more remarkable, is more than 1 μm particle, makes the removal ability of the utility model to microparticle stronger by ultrasonic coagulation by 0.3 μm of-1 μm of particle aggregation.
