Boiler ash removal system

Abstract

The invention provides a boiler ash removal system, which comprises a boiler body, an ash removal device, a transmission device, a control device and a terminal, and is characterized in that a pulse wave device is arranged in the ash removal device to generate sound wave vibration, compressed air energy is converted into high-strength sound waves, air molecules and particles acting in the area arevibrated through the sound wave energy, the combination of particles on the heat exchange surface or between particles is damaged and prevented to achieve the all-around remarkable ash removal effect. Besides, the boiler ash removal system is provided with a displacement sensor and a control device, so that the automation degree of ash removal, the efficiency of boiler ash removal, the productionefficiency of aluminum alloy and the accuracy of ash removal are effectively improved, and then the labor cost is reduced. In conclusion, the boiler ash removal system applicable to aluminum alloy production provided by the invention solves the problems that the ash removal is not comprehensive enough, the ash removal effect is poor, the ash removal efficiency is low, the ash removal cost is high, and the corrosion of an ash removal reagent on the boiler is great and the like.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a boiler dust cleaning system. Background technique [0002] Ash accumulation and slagging on the inner wall of the boiler are common phenomena in aluminum alloy processing. Generally, when the central temperature of the furnace body of the boiler is high, most of the ash is in a molten state, and when the temperature of the inner wall surface is low, the molten ash has solidified on the wall surface and is deposited on the wall surface to form ash deposits. If the ash particles are still in a melting or adhering state when they contact the wall or the ash layer on the wall, they will adhere to the wall to form a compact ash layer, which is called slagging. The ash and slagging on the inner wall of the boiler are mainly the result of the action of the aluminum alloy components during the processing of the aluminum alloy. Accumulation of ash and slagging on the heating area of ​​...

AI Technical Summary

Problems solved by technology

Accumulation of ash and slagging on the heating area of ​​the boiler will increase the heat transfer resistance and reduce the efficiency of the boiler. Boiler slagging will cause unstable operating conditions and affect production quality. It is important, but in the prior art, the aluminum alloy boiler dust removal device is generally cleaned by adding a dust removal agent, which has the disadvantages of inability to remove dust in all directions, poor effect of dust removal, high cost of dust removal, low degree of intelligence in dust removal, Dedusting reagents are highly corrosive and other issues

[0003] For example, the patent No. CN106224988A discloses a boiler cleaning device for charging, which includes a gas pipe provided with an air inlet and an air outlet and a drug storage device connected to the gas pipe. A first valve is provided between the gas port and the connection hole, a second valve is provided between the gas outlet and the connection hole; one end of the drug storage device is connected to the air pipe through the connection hole; The other end of the medicine storage device is equipped with a detachable cover, but there is still the problem that the dust removal device cannot achieve all-round dust removal

The patent No. US2115885A discloses a soot blowing and cleaning equipment for boilers, economizers, etc., but the cleaning equipment still has the problems of poor cleaning effect and low intelligence

[0004] To sum up, in the field of boiler dust removal device and dust removal system, there are still many practical problems that need to be dealt with in practical applications, and no specific solutions have been proposed.
