Problems solved by technology

However, as the dust accumulation on the bag in the bag filter chamber increases, the distribution of the flow velocity of the flue gas flow in the cross-section of the dust collector changes accordingly, which greatly affects the uniformity of the gas flow distribution in the front electrostatic precipitator chamber. The root mean square value of the flue gas flow distribution exceeds 0.3, which reduces the dust removal efficiency of the front electrostatic precipitator chamber and reduces the bag life of the rear bag filter chamber

Embodiment Construction

[0015] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0016] Electric cloth combined with dust collector air distribution adjustment method: multiple high-sensitivity anemometers installed on the cross-section of the dust collector detect the change data of the flue gas flow velocity, and the data is provided to the computer, and the computer and the preset The theoretical value is compared, comprehensively analyzed and processed, and then the command is output according to the calculation result, and the command is issued to the electric actuator 1. The electric actuator 1 drives the adjustment shaft 6 to rotate through the reducer 2 and the coupling 3. The guide vane group 7 also rotates accordingly, driving the angle of the guide vanes 11 to change, so that the flow velocity of the flue gas flow is rebalanced.

[0017] Airflow distribution adjustment device combined with electric cloth dust collector: it conta...

Abstract

A method for regulating the airflow distribution in electricity-cloth combined duster includes such steps as measuring the data about the variation of flue speed by multiple high-sensitivity anemometers arranged on the cross-section of duster, sending the data to computer, comparing it with a predefined theoretic value, analyzing, and outputting the instruction according to calculated result to control the rotation of guide blades. Its apparatus is composed of horizontal duster's casing, regulating axle controlled by computer, guide blades on said regulating axle, axle coupling, speed reducer, electric executor and multi-hole plate.

Description

Technical field: [0001] The invention relates to a method and a device for regulating the gas flow distribution of a dust collector, in particular to a method and a device for regulating the gas flow distribution of an electric cloth combined with a dust collector. Background technique: [0002] Chinese utility model patent "Electric filter bag filter", the patent number is 02224478.6, the electrostatic precipitator and the bag filter are installed in the same vertical shell, the lower end of the vertical shell is the air inlet, and the vertical shell The lower part of the vertical housing is the electrostatic precipitator chamber, which contains cylindrical anode plates, and a large cross cathode line is installed between the cylindrical anode plates. The upper part of the vertical shell is the bag filter chamber, which There are a number of tie-up cloth bags in the room, and the electrostatic dust removal chamber and the bag dust removal chamber communicate with each other...
