Abstract
The utility model provides a boiler primary air channel with vibration resistance and noise reduction, comprising an air channel. Transverse and longitudinal separator plates are disposed in the air channel, and the air channel is separated into a plurality of small air channels. The boiler primary air channel is advantageous in that the structure is simple and the use is convenient; through dividing and diverting concentrated air flow in the air channel, eddy current cannot be generated or the power of eddy current is reduced to the minimum; vibration elimination or reduction is realized; maintenance cost is greatly reduced and safety hidden trouble and noise are removed.
Description
The (1) technical field: the utility model relates to the architectural environment engineering, particularly is the air channel of boiler that is applied to the vibrationproof noise reduction of boiler of power plant cold air duct system.
The (2) background technology: at present, the vibration of its primary air fan outlet air channel various degrees of thermal power plant is because of there being a plurality of variable cross-sections on the air channel; Bend is rectangular; The dead angle, air channel is a lot, and air-flow forms eddy current easily in the air channel, and then causes that the air channel vibrates tempestuously and tears.Existing solution mainly still through increase the air channel wall thickness, strengthen air channel outer wall reinforcement, the method for setting up increase air channel intensity such as cross hang within it solves.The common deficiency that exists of these methods does, 1, antivibration to a certain extent, eliminate vibration, or the effect of vibration damping is relatively poor; 2, need regularly the air channel to be reinforced maintenance, maintenance cost is higher; 3, vibration noise is big, causes environmental pollution; 4, there is potential safety hazard, influences unit safety operation, reduce unit operation efficient.
The (3) summary of the invention: the purpose of the utility model is improved above shortcoming exactly.Propose a kind ofly effectively to weaken or eliminate vibration, reduce maintenance cost and noise, guarantee unit safety stable operation, improve unit operation efficient.
Air channel of the boiler of the utility model vibrationproof noise reduction has the air channel, it is characterized in that: horizontal and vertical dividing plate is set in the air channel, the air channel is separated into several little air channels.
The utility model is simple in structure, and is easy to use, through the focused airflow of decomposing and dredging the air channel people; It is minimum that the energy that makes it can not produce eddy current or its eddy current is produced is reduced to; Thereby play the effect of eliminating vibration or vibration damping, also greatly reduce maintenance cost, eliminate safe hidden trouble and noise.
The (4) description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1-air channel, 2-lateral partitions, 3-longitudinal baffle, the little air channel of 4-.
The (5) specific embodiment:
Referring to Fig. 1, the concrete scheme of the utility model is: have air channel 1, lateral partitions 2 and longitudinal baffle 3 are set in air channel 1, air channel 1 is separated into several little air channels 4.
Claims (1)
1. air channel of boiler of vibrationproof noise reduction has the air channel, it is characterized in that: horizontal and vertical dividing plate is set in the air channel, the air channel is separated into several little air channels.
