Problems solved by technology

[0003] The existing sonic soot blowing technology for boilers generally has limited sound power (within 800w), small effective soot blowing radius (2-3m), single function, and a large number of units used, which cannot solve the problem of coking in the furnace and cannot meet the needs of large boilers. Due to the need for ash removal, the scope of application is limited, and it is urgent to update and improve the technology

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] As shown in the figure, a high-power multifunctional sonic soot blower, the sonic generator is connected to the sonic transmission amplifier 5 through the air outlet pipe 4, the air source is connected to the sonic generator through the inlet pipe 3, and the sonic generator includes a stator 1 and a rotor 2. There are several holes or slots of different sizes on the rotor 2. The rotor is connected to the frequency conversion speed regulating motor 7 through a belt drive. A check valve 6 is installed between the air outlet pipe 4 and the stator 1. The sound wave generator is placed in a soundproof cabinet. Inside 8, the sound wave transmission amplifier 5 is flange-connected to the outlet end of the outlet pipe 4 outside the sound-proof case 8, the air source is flange-connected to the inlet end of the sound-wave generator inlet pipe 3 outside the ...

Abstract

The present invention discloses a multifunctional acoustic wave sootblower with ample power. A sound wave generator connects with a sound wave transfers magnifying apparatus through an air outlet duct, air source connects with the sound wave generator through the air inlet duct, the sound wave generator includes a stator and a rotor, the rotor is opened with some holes or grooves with various size, the rotor connects with a variable-frequency control motor through a transmission device. The sound wave generator uses a rotary valve type structure by cooperating with the motor which solves problem of ample power and adjustable problem of the sound wave sootblower, an efficient blowing action radius reaches above 12m.

Description

technical field [0001] The invention relates to a boiler sonic soot blower, in particular to a high-power multifunctional sonic soot blower. Background technique [0002] During the production and operation of the boiler, the surface of the heating surface (water wall, superheater, economizer, heat exchanger, flue, etc.) in contact with the coal combustion gas has ash accumulation, slagging and coking, which makes the boiler transmission The thermal effect is severely weakened, and the heat exchange efficiency is greatly reduced, resulting in a great waste of coal combustion calorific value, and at the same time, aggravating the corrosion and wear of the tube wall of the heating body, increasing the probability of boiler "pipe burst" accidents, and affecting safe production. Coking in the furnace also poses a great hazard to the safe operation of the boiler. [0003] The existing sonic soot blowing technology for boilers generally has limited sound power (within 800w), smal...
