Problems solved by technology

[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

Embodiment 1

[0017] Such as Figure 1 to Figure 3 As shown, the nozzle for the soot blower includes a nozzle 1, and the nozzle 1 includes a hollow cylindrical nozzle, and there are a plurality of cylindrical nozzles. Distributed in a 360-degree plane range. The inner cavity of the columnar nozzle is trumpet-shaped with a small inside and a large outside, and the inclination angle range of the inner wall of the columnar nozzle is within 15 degrees. The nozzle also includes a circular platform 2 extending outward along the outer periphery of the bottom of the cylindrical nozzle, and nozzles 3 are distributed around the circular platform 2, and the nozzles 3 are trumpet-shaped or stepped holes. Preferably, the stepped holes are in a stepped shape with the bottom being large and the top being small. It also includes a side wall 6 and an O-ring, the side wall 6 is fixed around the round table 2, there are screws 5 on the outer peripheral surface of the side wall 6 for connecting with the nozz...

Abstract

The invention relates to a nozzle for a soot blower, comprising a nozzle, the nozzle includes a hollow columnar nozzle, the inner cavity of the columnar nozzle is trumpet-shaped with a small inside and a large outside, and the inclination angle range of the inner wall of the columnar nozzle is within 15 degrees. When a pressurized gas source from the spray gun is distributed to the columnar nozzle, the gas is distributed to the columnar nozzle, and the gas goes from the inlet to the outlet, which is a process of sudden energy release. The compressed gas with pressure will become larger when it passes through the outlet. When the energy is released suddenly, the gas with the energy released will be sprayed around the surface of the heat exchanger, spreading the receiving area of ​​the surface of the heat exchanger. At the same time, all the columnar nozzles will generate sound waves when the gas energy is released, and the audio frequency exceeds 150 decibels. At the same time, it will cause the heat exchanger pipe network to vibrate with the audio frequency, and the dust on the surface of the heat exchanger will fall off with the vibration. The columnar nozzle is designed as a trumpet shape from the inside to the outside. The bell mouth is designed in this way to expand the surface area of ​​the heat exchanger and release energy audio sound waves 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...
