Sprayer for soot blower

Abstract

The invention relates to a sprayer for a soot blower. The sprayer comprises a nozzle, wherein the nozzle comprises hollow columnar nozzle bodies, an inner cavity of each columnar nozzle body is in theshape of a horn with a small inner part and a large outer part, and the inclination angle range of the inner side wall of each columnar nozzle body is within 15 degrees. According to the sprayer forthe soot blower, when a pressurized gas source from a spray gun is dispensed to the columnar nozzle bodies, gas is dispensed to the columnar nozzle bodies, and the process that the gas is dispensed from an inlet to outlets is a process of sudden release of energy; when the compressed gas with pressure passes through the outlets, the volume of the gas becomes larger, and when the energy is suddenlyreleased, the gas with the energy released is sprayed to the periphery of the surface of a heat exchanger, so that the receiving area of the surface of the heat exchanger is diffused; meanwhile, sound waves can be generated while the gas energy is released by all the columnar nozzle bodies, the voice frequency of the sound waves exceeds 150 decibels, a pipe network of the heat exchanger is causedto vibrate along with the voice frequency at the same time, and thus deposited soot on the surface of the heat exchanger falls off along with the vibration; and each columnar nozzle body is designedin the shape of the horn with the small inner part and the large outer part, due to the design of a horn mouth, the surface area of the heat exchanger is enlarged, and the energetic voice frequency sound waves are released at the same time.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a nozzle for a soot blower. Background technique [0002] At present, the sootblowers (air shock wave, acetylene blasting sootblower) manufactured by domestic and foreign manufacturers all adopt the straight pipe blowing form, with a single and simple structure, while the rotary nozzle, due to the space structure, the medium is flue gas dust, and it is high temperature. , easy to enter the dust, and locked, unable to rotate, difficult to maintain, only need to stop to repair and clean, due to high temperature, the rotating nozzle is easy to oxidize and burn, and it is not easy to repair. Contents of the invention [0003] The purpose of the present invention is to provide a nozzle for a soot blower, which can also achieve the effect of cleaning dust, and because there is no need to rotate, the sealing effect between the nozzle and the nozzle pipe is good, and no locking phenomenon occu...
