Abstract
The present invention provides a kind of injection pipeline muffler of dust pelletizing system.The present invention includes injection pipeline, and mineral wool layer is provided with outside the injection pipeline, and the mineral wool layer space outside is provided with fixed ring, and the fixed ring is filled with sound-absorbing material layer by damping device connected with outer casing between the shell and the mineral wool layer.The present invention effectively reduces the noise during injection, while not interfering with the air pressure of blast pass, stable and reliable in work.
Description
Technical field：
The present invention relates to a kind of injection pipeline mufflers of dust pelletizing system, belong to environmentally friendly preparing technical field.
Background technology：
Pulse blowing bag type dust precipitator is a kind of the most commonly used deduster, the course of work be when dusty gas by air inlet into
Enter deduster, initially strike inclined plate and baffle among inlet and outlet, air-flow, which just turns to, flows into ash bucket, while air velocity is put
Slowly, due to effect of inertia, crude particle dust in gas is made to flow directly into ash bucket.Play a part of to gather dust in advance, into the air-flow of ash bucket
Then folding and the outer surface of filter bag is trapped in upwardly through the internal filter bag dust equipped with metallic framework, purified gas into
Enter baghouse top clean room, air outlet discharge is pooled to, during dusty gas is purified by filter bag, with the increasing of time
Add and the dust that is attached on filter bag of product is more and more, increase resistance of the filter bag, causes to handle air quantity and gradually decrease, for normal work,
Control resistance in a certain range（The 140-170 millimeters of water）, it is necessary to deashing is carried out to filter bag, by pulse control instrument when deashing
Each control valve unbalanced pulse valve of sequence trigger switch, compressed air in gas bag is by each hole of injection tube through Wen's pipe inspection to each corresponding
In filter bag, filter bag moment drastically expands, and product is made to be attached to the dust releasing on filter bag surface, and filter bag is regenerated.Dust lower clearly is fallen into
Body is discharged through dust removing system in ash bucket.Thus so that product is attached to the pulse jetting deashing periodically of the dust on filter bag, make purification gas
Normal through guarantee dust pelletizing system operation.
During injection, noise caused by air-flow is very big, seriously affects working environment, is directed to the noise reduction of pipeline at present
Device is generally arranged in the form inside pipeline using by silencing means, and the effect of silencer is exactly by the exhaust that reduces, decays
Noise is eliminated in the pulsation of pressure, but injection pipeline is directly set noise reduction since the blast pass pressure of needs is larger
Standby arrangement plays the role of decompression in the duct to injection, to influence to be blown effect.
Invention content
The purpose of the present invention is providing a kind of injection pipeline muffler of dust pelletizing system in view of the above problems, effectively
The noise during injection is reduced, while not interfering with the air pressure of blast pass, it is stable and reliable in work.
Above-mentioned purpose is achieved through the following technical solutions：
The injection pipeline muffler of dust pelletizing system, including injection pipeline are provided with mineral wool layer outside the injection pipeline, described
Mineral wool layer space outside is provided with fixed ring, the fixed ring by damping device connected with outer casing, the shell with it is described
Sound-absorbing material layer is filled between mineral wool layer.
The injection pipeline muffler of the dust pelletizing system, the distance between adjacent described fixed ring are not more than 1 meter.
The injection pipeline muffler of the dust pelletizing system, the damping device include damping spring, the damping bullet
One end of spring is connected in the fixed ring, and the other end connects on the housing.
The injection pipeline muffler of the dust pelletizing system, each fixed ring pass through three damping springs and shell
Connection.
The injection pipeline muffler of the dust pelletizing system, the sound-absorbing material layer use flame retardant polyurethane sound absorber
Material.
Advantageous effect：
1. the present invention uses the silencing means of pipeline peripheral hardware, traditional pipe muffler is avoided with shunt pressure, is reduced, decaying
Pressure at expulsion is pulsed to eliminate influence of the noise to injection pipeline air pressure, while sound-absorbing effect is good, does not influence to be blown effect,
It is stable and reliable in work.
2. the sound-absorbing material layer of the present invention uses flame retardant polyurethane sound-absorbing material, high pressure gas and pipe during injection are avoided
Road friction generates a large amount of heat and sound-absorbing material is caused to burn, safe.

4 connected with outer casing 5 of device is filled with sound-absorbing material layer 6 between the shell and the mineral wool layer.Using the noise reduction of pipeline peripheral hardware
Device avoids traditional pipe muffler with shunt pressure, reduces, the pulsation of decaying pressure at expulsion eliminates noise to injection
The influence of pipeline air pressure while sound-absorbing effect is good, does not influence to be blown effect, stable and reliable in work.
The injection pipeline muffler of the dust pelletizing system, the distance between adjacent described fixed ring are not more than 1 meter.
The injection pipeline muffler of the dust pelletizing system, the damping device include damping spring, the damping bullet
One end of spring is connected in the fixed ring, and the other end connects on the housing.
The injection pipeline muffler of the dust pelletizing system, each fixed ring pass through three damping springs and shell
Connection.
The injection pipeline muffler of the dust pelletizing system, the sound-absorbing material layer use flame retardant polyurethane sound absorber
Material.
It should be pointed out that above-mentioned embodiment is only intended to clearly illustrate example, and not to embodiment
It limits, there is no necessity and possibility to exhaust all the enbodiments.Each component part being not known in the present embodiment
It is realized with the prior art.For those skilled in the art, in the premise for not departing from the principle of the invention
Under, several improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
