Description
Technical Field
The utility model relates to a waste heat boiler ash removal technical field, concretely relates to machinery shakes and beats ash handling equipment.
Background
The hot flue gas of the SP waste heat boiler contains a large amount of dust, and the dust is fine and easy to deposit on the heating surface of the boiler, so that the heat transfer effect of the heating surface of the boiler is influenced. Therefore, the problem of dust accumulation on the heating surface of the boiler is solved, and the SP waste heat boiler is the most basic problem to be solved. In order to prevent dust deposition, improve the thermal efficiency of the boiler and realize the purpose of safe and stable operation of the boiler, a dust cleaning device is generally adopted by combining the actual operation condition and the specific structural characteristics thereof. The ash removal device commonly used by the SP waste heat boiler at present mainly comprises: soot blower, sound wave soot cleaning, combustible gas deflagration soot blowing and mechanical rapping device.
Soot blowing of soot blowers is a mechanical soot cleaning mode commonly used by waste heat boilers, dozens of soot blowers or even hundreds of soot blowers are often installed on one boiler, one-time investment is large, dead corners are swept, soot cleaning is incomplete, and operation cost is high.
The vibration diaphragm of the acoustic wave soot blower is difficult to manufacture, high in manufacturing cost, large in maintenance workload, high in cost and harmful to human bodies due to continuous noise of more than 140 decibels, and needs to be replaced continuously.
The gas detonation soot blowing system is complex, the safety is poor, the equipment cost is high, and the investment is large.
The mechanical rapping device uses a small-capacity motor as power, and uses a rapping hammer to sequentially hammer the heating surface of the boiler, so that the heating surface is strongly vibrated at the moment of hammering, and the adhered deposited dust is stressed repeatedly to generate tiny cracks until the adhesive force of the deposited dust is damaged and falls off. The mechanical rapping has the advantages of low power consumption and no additional medium added to the flue gas. But has the disadvantage of having a certain degree of adverse effect on the service life and strength of the boiler tube and the weld seam, but the service life can be prolonged as long as the design is protected.
For example, patent document with application number "CN 201621112002.0" discloses a rapping device for dust removal of SP waste heat boiler of cement kiln, although this utility model can promote certain dust removal efficiency, its structure is comparatively complicated, and the cost is higher.
