Description

Chemical industry safety in production dust collector Technical Field The invention relates to the technical field of dust removal, in particular to a dust removal device for chemical safety production. Background At present, in numerous fields of industrial production, ore processing, chemical smelting and the like, a large amount of waste gas with dust is often generated, and in order to protect the ecological environment and the physical health of workers, the dust-containing gas must be filtered and purified, wherein a bag-type dust collector is widely applied due to high dust collection efficiency and strong adaptability. The working principle of the bag-type dust collector is that dust is intercepted on the outer surface of a filter bag when dust-containing gas passes through the filter bag, purified gas is discharged from the inner part of the filter bag, and as the working time is prolonged, more and more dust is adsorbed on the outer surface of the filter bag, so that the running resistance of the dust collector is increased, the filtering efficiency is reduced, and therefore the filter bag is required to be subjected to ash cleaning treatment regularly. At present, when the existing bag dust remover in the market is used for removing dust, the vast majority of bag dust removers adopt a pulse back blowing dust removing technology, namely, the bag is impacted by the high-pressure gas sprayed instantly, so that the bag is expanded and deformed to shake off dust, however, the traditional single-airflow dust removing mode has the following obvious defects in actual use: the ash removal force is limited, and blockage is easily caused, wherein the inside of a traditional cloth bag is supported by a rigid metal framework bag cage, the cloth bag lacks the capability of active vibration ash removal, and the dust which is compacter or has a certain viscosity is difficult to thoroughly strip by the impact of high-pressure airflow, so that the micropores of the filter bag are easily blocked for a long time, the negative pressure resistance of the exhaust of a system is increased, and the service life of the cloth bag is shortened; the existing ash removal structure is single, high-frequency and instant mechanical and physical vibration can not be provided for assisting ash falling when the airflow is blown, so that the maintenance frequency of the integral dust remover is high, and the working efficiency is limited. Therefore, how to design a dust removing device capable of effectively avoiding the dust on the outer side of the cloth bag from being thoroughly shaken off in a mode of combining physical vibration and airflow becomes a technical problem to be solved by the person skilled in the art. Disclosure of Invention Therefore, in view of the above problems, the present invention provides a dust removing device for chemical safety production, which solves the above technical problems.
