Description

TECHNICAL FIELD

[0001] The utility model relates to a boiler ash removal technical field, concretely is a kind of ultrasonic speed three-dimensional vector boiler ash removal device. BACKGROUND

[0002] When boiler is in low load operation, due to the low flow velocity of flue gas of boiler, a large amount of ash particles in flue gas are deposited on the tube plate of preheater, when the ash deposited on the surface tube plate of preheater partially or entirely blocks the pipe opening, the flue gas flow through the pipe is reduced or interrupted, the heat of high-temperature flue gas heating pipe wall is reduced, resulting in the temperature drop of pipe wall. When the temperature of the pipe is lower than the dew point temperature of flue gas (136℃), the flue gas in the pipe will condense, and the ash deposited in the pipe opening will be caked after the condensation of flue gas. The caked ash is in a high temperature and will soon become hard and firmly adhere to the pipe wall, thereby causing the pipe opening to be blocked. The above phenomenon will be accelerated when the boiler is in long-term low load operation.

[0003] In addition, fuel oil is used when boiler is started and ignited, and the oil stains produced by combustion are bonded on the surface of tail air preheater, which will also cause the ash and scale on the surface of pipe, and the above ash and scale may eventually cause the pipe opening to be blocked if not treated in time, thereby affecting the normal operation and safety of boiler.

[0004] In summary, ash removal operation needs to be carried out regularly during the use of boiler, and ash removal device needs to be used during ash removal. The ash removal device in the prior art, such as the Chinese patent with application number 201820892261.2 and authorization announcement number CN208431941U and name "a gas condensing boiler convenient for ash removal", discloses a gas condensing boiler convenient for ash removal, which belongs to the field of condensing boiler and comprises: a boiler body, a partition plate group arranged in the inner cavity of the boiler body and used for separating the inner cavity of the boiler into flues, a heat exchange pipe arranged in the flue and penetrating through the partition plate group, and a cleaning pipe penetrating through the partition plate group and arranged outside the heat exchange pipe, wherein the cleaning pipe is provided with a nozzle arranged in the flue and having a spraying direction towards the heat exchange pipe, and the cleaning pipe is used for being communicated with an external water pipe.

[0005] The cleaning pipe in the above patent is communicated with the external water pipe outside the boiler body, and the water flow in the external water pipe is sprayed out through the nozzle to flush the outer surface of the cleaning pipe, so that the accumulated ash is removed and the thermal efficiency of the condensing boiler is ensured. The prior art such as the above patent can improve the ash removal efficiency to a certain extent. However, the prior art such as the above patent generally directs the nozzle towards the inside of the boiler for blowing. However, it is known that a large number of pipe rows are usually arranged on the boiler to meet the needs of operation of the boiler, and the gaps between the pipe rows will also cause the accumulation of ash. However, the ash removal device in the prior art is difficult to effectively remove the accumulated ash between the gaps of the pipe rows during ash removal operation due to the blockage of the pipe rows, and there is a certain deficiency.
