On one hand, the invention also provides a dust cleaning method of the dust remover.

The technical scheme is as follows: a dust cleaning method for a dust remover is characterized in that when dust is cleaned, a gap formed between each injection pipe and a corresponding dust cleaning unit is sealed.

The invention principle is as follows:

the inventor of the invention finds that the dust removing principle of the filter bag made of cloth materials is as follows through research in production practice: after the air current got into the filter bag, the pressure difference between the pressure in the filter bag and the pressure outside the filter bag produced the change (when the air current just got into, the pressure in the filter bag was greater than the pressure outside the filter bag, then along with gaseous outflow, the pressure in the filter bag equaled the pressure outside the filter bag), because the filter bag is the cloth, thereby cause the earlier shrink of expansion of filter bag, thereby produce the vibration, in addition get into the air current with dust removal air current opposite direction, there is certain reverse purging effect, thereby make the dust of long-pending attainment on the filter bag filtration pore wall drop and leave the filter bag, consequently, effective deashing can be carried out.

However, when the material of the filter bag is a material capable of resisting high temperature (such as metal like stainless steel), because the material does not expand and contract with the difference between the pressure inside the filter bag and the pressure outside the filter bag, therefore, the dust accumulated on the filter hole walls of the filter bag can not be fallen off and separated from the filter bag through vibration, and because the diameter of the filter bag is far larger than that of the injection tube (generally, when the diameter of the filter bag is 160mm, the diameter of the injection tube is about 42 mm), therefore, the sectional area of the filter bag is far larger than that of the injection tube, and therefore, after the airflow from the injection tube enters the filter bag and contacts with the inner wall of the filter bag, because the gap between the injection tube and the mouth of the filter bag is far larger than the area of the filter hole of the filter bag, therefore, most of the air flow returns from the gap between the injection pipe and the mouth of the filter bag quickly, and high-pressure turbulent flow cannot be formed in the filter bag to blow the hole wall of the filter hole outwards, so that the dust removing effect is basically not achieved during dust removing.

Compared with the prior art, the invention has the beneficial effects that:

according to the invention, the space between the injection pipe and the filter bag is sealed, so that when dust is cleaned, airflow from the injection pipe enters the filter bag and then contacts with the inner wall of the filter bag, and the airflow can only be blown out of the filter hole because no gap exists between the injection pipe and the filter bag opening, so that the airflow in the filter bag forms turbulent flow to form high pressure, and the airflow is blown out of the filter hole under the action of the high pressure, so that dust accumulated on the wall of the filter hole of the filter bag is dropped off from the filter bag, and effective dust cleaning is realized.
