Detailed Description

In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.

The noise-reduction fire-extinguishing type swirler comprises a swirler body 5, an inlet flange 1 is connected above the swirler body 5, a silencing tube 4 is arranged below the inlet flange 1, silencing cotton 2 wraps the silencing tube 4, and when airflow silencing small holes are formed, the frequency spectrum of airflow noise can move to high frequency or ultrahigh frequency, so that audible components in the frequency spectrum are obviously reduced; the silencing cotton is wrapped outside to completely absorb the sound wave vibration energy, the silencing orifice plate 3 is arranged on the silencing barrel 4, the noise is greatly reduced by utilizing the small-hole silencing principle, the fire retardant element 6 is arranged below the silencing barrel 4, the stainless steel strip is adopted to manufacture a ring, the stainless steel corrugated plate is filled in the middle, the stainless steel strip is used to manufacture a plurality of concentric rings, and the gap between the ring and the ring is 1.2 mm; the stainless steel corrugated pipe is filled in the gap of the circular ring, the height of the corrugated pipe is 1.2mm, the thickness of the corrugated pipe is 0.2mm, the function of fire extinguishing is achieved through heat transfer cooling and wall effect by a tiny airflow channel, the inner wall of the silencing tube 4 positioned above the fire retardant element 6 is the sound deadening hole plate 3, the secondary rectifier 7 is arranged below the fire retardant element 6, the secondary rectifier 7 is formed by welding the circular ring and the folded plate by adopting a carbon steel thin steel belt, the thickness of the carbon steel thin steel is 1-3mm, the airflow resistance is reduced, the disturbance of the airflow is reduced, the airflow flow tends to be smooth and the noise is reduced, the primary rectifier 8 is arranged below the secondary rectifier 7, the primary rectifier 8 is formed by welding the rectifiers, the thickness of the primary rectifier 8 is, the air flow is regulated and guided preliminarily, so that the air flow tends to be gentle, an ash discharge port is arranged below the cyclone body 5, and a boiler flue gas outlet is arranged above the cyclone body.

1) The airflow collides with the cylinder wall after entering the cylinder, spirally goes downwards, turns 180 degrees and flows upwards, and the dust is deposited in the dust hopper at the bottom of the cyclone under the action of gravity and inertia force. When the ash level reaches a certain height, the ash is discharged from the ash discharge port at the lower part.

2) The airflow passes through the primary rectifier and the secondary rectifier in sequence. The primary rectifier is welded by the rectifier, and primary regulation and guidance are carried out on the airflow, so that the airflow tends to be smooth; the air flow resistance is reduced, the disturbance of the air flow is reduced, the air flow is further smooth, and the noise is reduced.

3) After rectification, smooth airflow enters the fire retardant element. Fire-retardant component principle of putting out a fire: one is based on heat transfer; the second is based on the wall effect.

One of the requirements for combustion needs is to reach the ignition point below which combustion will stop. According to this principle, the spread of the flame can be prevented by simply lowering the temperature of the burning material below its ignition point. The flame will become several tiny flames after passing through the many tiny passages of the flame retardant element. The fire retardant element is specially designed, so that the contact area with flame is greatly increased, the heat transfer is enhanced, the temperature of the flame is reduced to be below the ignition point, and the flame is prevented from spreading.

The combustion and explosion are not direct intermolecular reaction, but are excited by external energy, molecular chains are destroyed to generate activated molecules, the activated molecules are split into short-life and very active free radicals, the free radicals collide with other molecules to generate new products, and meanwhile, new free radicals are generated to continue to react with other molecules. As the burning combustible gas passes through the narrow passage of the flame retardant element, the probability of collision of free radicals with the passage wall increases and the free radicals participating in the reaction decrease. When the channel is narrow to some extent, this wall effect creates a condition where the flame cannot continue to propagate, i.e., the flame is blocked.

4) When the airflow enters the silencing cylinder and the silencing cotton, when the airflow silencing small holes are formed, the frequency spectrum of the airflow noise can move to high frequency or ultrahigh frequency, so that audible components in the frequency spectrum are obviously reduced; the noise reduction cotton is wrapped outside to thoroughly absorb the sound wave vibration energy.

5) The airflow finally enters the silencing orifice plate, and when the airflow passes through the small holes, the frequency spectrum of the jet noise moves to high frequency or ultrahigh frequency, so that audible components in the frequency spectrum are obviously reduced, and the interference and the damage to people are reduced.
