Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, specifically a novel electrostatic precipitator-baghouse composite dust collector. Background Technology
[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas it can handle, the resistance loss of gas passing through the collector, and its dust removal efficiency. A baghouse dust collector is one type of dust collector.
[0003] Existing baghouse dust collectors cannot achieve an integrated composite design of baghouse dust collection and electrostatic precipitator, resulting in poor dust collection efficiency. Therefore, there is an urgent need for a new type of electrostatic precipitator-baghouse composite dust collector to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a novel electrostatic precipitator-baghouse hybrid dust collector to solve the problem mentioned in the background art that existing baghouse dust collectors cannot achieve integrated composite design of baghouse dust collection and electrostatic precipitator, resulting in poor dust collection effect.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A novel electrostatic precipitator / baghouse hybrid dust collector includes a filter chamber with supporting feet at its bottom. Three discharge funnels are located in the middle of the bottom of the filter chamber. A dust-laden gas inlet and a purified gas outlet are located on the left side of the filter chamber. An airflow distribution plate is located inside the filter chamber near the dust-laden gas inlet. An electric field bed is located inside the filter chamber and to the right of the airflow distribution plate. A baghouse area is installed inside the filter chamber and to the right of the electric field bed. An air jet pipe is located inside the filter chamber and directly above the baghouse area. Six air jet nozzles are located at the bottom of the air jet pipe. An air supply pipe is connected to the upper right end of the filter chamber via a vent. The end of the air supply pipe is connected to the top of the purified gas outlet. The right end of the air jet pipe passes through the right side wall of the filter chamber and is connected to a compressed air manifold. A solenoid valve is installed on the top of the compressed air manifold. The six air jet nozzles face the filter bags in the baghouse area.
[0007] As a preferred embodiment of this utility model, the number of the support legs is set to four, and the four support legs are arranged alternately with the three discharge funnels.
[0008] As a preferred embodiment of this utility model, each of the three discharge hoppers is equipped with a discharge valve.
[0009] As a preferred embodiment of this utility model, the number of vents is set to three, and the three vents are arranged horizontally at equal intervals.
[0010] As a preferred embodiment of this invention, the six jet nozzles are arranged horizontally at equal intervals at the bottom of the jet pipe.
[0011] As a preferred embodiment of this utility model, the gas transmission pipeline is L-shaped.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention integrates baghouse dust collection and electrostatic precipitator design by incorporating a baghouse area, an electric field bed, and an airflow distribution plate. During operation, dust-laden gas is introduced into the filter chamber through the gas inlet and then flows through the airflow distribution plate into various channels of the electric field bed. Dust particles become charged within these channels, and both charged and uncharged particles are carried by the airflow to the perforated electrode plates. Some charged dust particles are deposited on the electrode plates, while the remaining charged or uncharged dust particles enter the filter bags in the baghouse area. The dust is filtered onto the outer surface of the filter bags, and the purified gas flows from the inner cavity of the filter bags through vents into the upper gas delivery pipe, and then exits from the purified gas outlet. This design achieves an integrated composite design of baghouse dust collection and electrostatic precipitator, thereby improving the dust removal efficiency. Attached Figure Description

This allows for the integration of bag filter dust removal and electrostatic precipitator into a composite design, thereby improving the dust removal effect.
