Abstract

The invention relates to a bag type dust collector modified from an electric dust collector. The bag type dust collector comprises a bracket, a box, a spraying blowing device, a filtering bag component and a control device, wherein the filtering bag component is composed of a filtering bag and a bag cage; a pneumatic butterfly valve is arranged on an air inlet channel in the box; an air inlet channel switching mechanism is arranged on the upper surface of the box; an ash bucket is arranged on the lower surface of the box; the spraying blowing device is connected with an air compressing device through a pipeline; the air compressing device is connected with the pneumatic butterfly valve; the control device comprises an impulse controller; the impulse controller is connected with the spraying blowing device through a circuit; the control device comprises a PLC (Programmable Logic Controller); and the PLC is connected with the pneumatic butterfly valve through a solenoid valve. Compared with the prior art, the present electric dust collector is modified into the bag type dust collector according to the invention, so that the materials are saved, the modifying cost is lowered, the de-dusting effect is good and the present national environmental protection regulation demand is met. The PLC is adopted by the bag type dust collector for automatically adjusting pulse intervals, the spraying blowing times is reduced and the service life of the easily damaged parts is prolonged.

Description

technical field [0001] The invention relates to a dust removal device, in particular to a bag type dust collector obtained by refitting an electric dust collector. Background technique [0002] Domestic electric power, cement and steel industries are equipped with a large number of old-style electrostatic precipitators. The dust removal efficiency and dust removal effect of this type of electrostatic precipitator are poor, and they can no longer meet the requirements of current national environmental protection regulations. The bag filter has no strict requirements on the specific resistance of coal-fired soot, and has the advantages of high dust removal efficiency and good dust removal effect, and its purification efficiency can reach 99%. If all the existing electrostatic precipitators that are still in use are changed to bag filter, it will not only be a huge project and expensive, but also cause a lot of equipment scrapping and material loss, which is unbearable for indu...
