Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings.

[0009] As shown in the figure, the air inlet valve 6 on the air inlet pipe 5 of the pneumatic board-type isolation door cleaning device of the present invention is connected with the compressed air pipeline, and the air outlet pipe 7 is connected with the soot-blowing pipe of the pneumatic board-type isolation door. Control the compressed air pipeline, open the intake valve 6, and the gas storage tank 3 stores gas. The control circuit controls the pulse solenoid valve 2 to blow high-pressure and high-frequency gas in a regular cycle to remove dust from the door track. The solenoid valve 2 is located in the gas storage tank 3 Between the check valve 1 and the check valve 1, the check valve 1 controls the flow direction of the gas in the outlet pipe 7, cuts off the flow of the high-temperature and high-pressure gas in the air duct to the pulse solenoid valve 2, and protec...

Abstract

The invention relates to a deashing device for a pneumatic plugboard isolated door and belongs to the technical field of power station auxiliary equipment. The deashing device for the pneumatic plugboard isolated door comprises an air storage tank, wherein the air storage tank is provided with an air inlet pipeline and an air outlet pipeline; an air inlet valve is arranged on the air inlet pipeline; a pulse solenoid valve and a check valve are arranged on the air outlet pipeline; and the solenoid valve is positioned between the air storage tank and the check valve. When the deashing device for the pneumatic plugboard isolated door operates, the air inlet valve is opened, the compressed air enters the air storage tank through the air inlet pipeline, a control circuit controls the pulse solenoid valve to circularly blow high-pressure and high-frequency gas at regular time, deashing is conducted on a door sheet track, the check valve controls the flow direction of gas in the pipelines, the high-temperature and high-pressure gas in an air duct is prevented from flowing to the pulse solenoid valve, and the pulse solenoid valve is protected against being damaged by the high-temperature and high-pressure gas. As the improvement of the deashing device, a filter is arranged on the air intake pipeline to prevent impurities in the compressed gas from entering the deashing device to influence normal operation of the valves.

Description

technical field [0001] The invention belongs to the technical field of power station auxiliary machines, and in particular relates to a pneumatic dust cleaning device. Background technique [0002] Due to the large amount of coal ash contained in the air of the hot primary air duct of the power station boiler, the interior of the pneumatic sliding plate isolation door installed in this air duct is seriously ash-accumulated, and the door panel switch often fails due to ash accumulation, which affects the safe operation of the boiler. And inspection and maintenance bring hidden dangers and inconvenience. Contents of the invention [0003] In view of the above technical problems, the present invention provides a pneumatic plate-type isolation door dust cleaning device that can regularly and automatically clean the isolation door. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is that a pneumatic plat...
