[0003] Yet the weak point of above-mentioned Chinese patent No. 200820109478.8 " acoustic wave soot cleaning bag filter " invention patent is only to be provided with a described acoustic wave soot cleaning device positioned at the top of the dust collector casing, influences the dust accumulated on the bag. The effect of cleaning; secondly, when the flue gas temperature is too high or the filter pressure difference is too large, the damage to the filter bag of the bag filter cannot be effectively protected, so the reliability and safety of use are poor

Embodiment Construction
[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] Such as Figure 1 to Figure 3 As shown, it includes a bag filter 1 with a bag 11. The bag filter is provided with a plurality of sonic dust cleaners 15. The advantage of the sonic cleaner is that it will not bring air and moisture into the bag during the cleaning work. , and there will be no temperature change during cleaning. The lower part of the bag filter has a dust discharge valve 14 and an ash hopper 4 for collecting dust.
[0023] The bag filter 1 is provided with a flue gas inlet 2 and an air outlet 3, and the air outlet discharges the dust-removed flue gas from the chimney 22 through the induced draft fan 21; Settling action at low speeds to improve dust removal.
[0024] The bag filter 1 of the present invention is arranged symmetrically on the left and right sides of the bypass valve 9 respectively, forming a group of soni...

A sound-wave bag-type dust removal device comprises bag-type dust removers provided with a plurality of sound-wave ash-removal devices which are arranged on the top and four side faces of the bag-typedust remover; the adjacent sides of the sound-wave ash-removal devices are arranged at intervals so as to form spiral vibrating sound wave; the bag-type dust removers are respectively symmetrically arranged on both the left side and the right side of a by-pass valve, and the upper part of the valve core of the by-pass valve is communicated with an air inlet and the lower part thereof is communicated with an air outlet so as to close or open a channel between the air inlet and the air outlet when the valve core moves; and an air-inlet control valve is arranged in an upper channel of the air inlet and an air-outlet control valve is arranged in a lower channel of the air inlet, and both the air-inlet control valve and the air-outlet control valve are provided with a pressure difference transmitter and a temperature sensor and are connected with a PLC control system. The sound-wave bag-type dust removal device has the advantages that the effect of cleaning the dust collected on bags is excellent and the reliability, safety and service life are better.
Description
technical field [0001] The invention relates to the technical field of a flue gas dust removal device, in particular to a sonic bag dust removal device. Background technique [0002] At present, various types of sonic bag dust removal devices have been widely used at home and abroad. For example, Chinese Patent No. 200820109478.8 discloses an invention patent of "sonic dust cleaning cloth bag filter", which is a kind of dust removal device that uses sound wave dust removal device, air volume control butterfly valve and dust removal bag to collect dust with high moisture content, high viscosity and fine particle size. Dust sonic cleaning bag filter. The structure of the sonic dust cleaning bag filter includes a sonic soot cleaner, a bag and a bag frame, a dust collector outlet, a dust collector box, a star-shaped ash unloading valve, and an ash hopper. The sonic soot cleaner is located in the On the top of the dust collector box, the air inlet is connected to the ash collec...
