Example Embodiment

[0025] Embodiment 1: A bag-type dust collector for acoustic wave cleaning, comprising: a box body 1 for support and protection; an air inlet 2 provided on one side of the box body 1 and an air outlet 4 on the opposite side, respectively used for Pass in dusty gas and discharge clean gas. The air inlet 2 controls the filtering wind speed below 1.0m / min; the air outlet 4 is connected to a negative pressure fan to maintain a negative pressure environment in the cabinet 1. The ash hopper 5 is arranged under the box body 1 to receive the dust collected by the dust collector. A column is also arranged under the ash hopper 5 to play a supporting role.

[0026] It also includes a sound wave generator 3 arranged on the box body 1 for cleaning the dust deposited on the surface of the filter bag inside the box body 1. The sound wave generator 3 is arranged on the side wall of the box 1, and the frequency setting of the sound wave generator and the size of the box 1 need to meet the followi...

Example Embodiment

[0033] Example 2: An electric dust collector for acoustic wave cleaning, such as figure 2 As shown, it includes: a box body 1 used for support and protection; an air inlet 2 provided on one side of the box body 1 and an air outlet 4 on the opposite side are respectively used to pass in dusty gas and discharge clean gas. The air inlet 2 controls the filtering wind speed below 1.0m / min; the air outlet 4 is connected to a negative pressure fan to maintain a negative pressure environment in the cabinet 1. The ash hopper 5 is arranged under the box body 1 to receive the dust collected by the dust collector. A column is also arranged under the ash hopper 5 to play a supporting role.

[0034] It also includes a sound wave generator 3 arranged on the box body 1 to clean the dust deposited on the surface of the polar plates and polar lines inside the box body 1. The sound wave generator 3 is arranged on the top of the box 1, and the frequency setting of the sound wave generator and the ...

Abstract

The invention relates to a deduster and discloses an acoustic deashing and dedusting device. The acoustic deashing and dedusting device comprises a box, an air inlet, an air outlet, an ash bucket arranged below the box and a negative pressure draught fan connected with the air outlet. The acoustic deashing and dedusting device is characterized by further comprising an acoustic transmitter. According to the invention, acoustic deashing technology is employed, and dust accumulated on pole plates and pole wires of an electric precipitator or on the filter material of a bag filter can be effectively removed. The acoustic deashing and dedusting device can remove dust accumulated on the surface of the pole plates or filter material and has the advantages of a good deashing effect, a simple structure, high purifying efficiency, long service life, safe and reliable operation and a high degree of automation.

Description

[0001] technical field [0002] The invention relates to a dust remover, in particular to a dust remover which utilizes sound waves to remove dust. Background technique [0003] With the development of industrial production and the improvement of people's awareness of environmental protection, coupled with various smog phenomena and the national environmental standards for dust concentration emission requirements, various dust removal technologies have been developed, and various dust collectors have come into being. pregnancy. [0004] So far, electrostatic precipitators and bag (cartridge) precipitators are the most widely used dust collectors. Whether it is an electrostatic precipitator or a bag filter, there is a common problem, that is, it is difficult to clean the dust. Electrostatic dust removal relies on mechanical rapping of the plate of the dust collector to remove dust. Long-term mechanical rapping will inevitably cause damage to the plate or pole line and the me...
