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
The invention belongs to the power plant auxiliary machine technical field, relate in particular to a kind of pneumatic deashing device.
Background technology
Owing to contain a large amount of coal ash in the station boiler heat primary air road air, the pneumatic inserting board type isolating door internal junction ash that causes being installed in this air channel is serious, often occur causing the door-plate malfunctioning switch because tying grey bite, thereby bring hidden danger and inconvenience for safe operation and the repair and maintenance of boiler.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of pneumatic inserting board type isolating door deashing device that can regularly, automatically carry out to isolation door deashing.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of pneumatic inserting board type isolating door deashing device comprises air accumulator, described air accumulator is provided with admission line and outlet pipe, be provided with intake valve at described admission line, be provided with impulse electromagnetic valve and check-valves at described outlet pipe, described magnetic valve is between air accumulator and check-valves.
During the pneumatic inserting board type isolating door deashing device work of the present invention; open intake valve compressed air and enter air accumulator by admission line; control circuit control impuls magnetic valve timing cycle blows high voltagehigh frequency gas; the end of door plate track carries out ash disposal; the gas flow of check-valves control pipeline; block that high temperature and high pressure gas flows to impulse electromagnetic valve in the air channel, the protection impulse electromagnetic valve is not damaged by high temperature and high pressure gas.
Further improve as the present invention, described admission line is provided with filter, prevents that the impurity in the Compressed Gas from entering in the deashing device, affects the regular event of valve.
Description of drawings
Accompanying drawing is the pneumatic inserting board type isolating door deashing device of the present invention syndeton schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is made and to further specify.
As shown in the figure; intake valve 6 on the pneumatic inserting board type isolating door deashing device of the present invention admission line 5 joins with compressed air line; outlet pipe 7 links to each other with pneumatic inserting board type isolating door blowing pipe; intake valve control compressed air line; open intake valve 6; air accumulator 3 carries out gas storage; control circuit control impuls magnetic valve 2 timing cycles blow high voltagehigh frequency gas; the end of door plate track carries out ash disposal; magnetic valve 2 is between air accumulator 3 and check-valves 1; the 7 interior gas flows of check-valves 1 control outlet pipe block that high temperature and high pressure gas flows to impulse electromagnetic valve 2 in the air channel in, protect impulse electromagnetic valve not damaged by high temperature and high pressure gas.
As preferably, admission line 5 is provided with filter 4, prevents that the impurity in the Compressed Gas from entering in the deashing device, affects the regular event of valve.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
