Abstract
The utility model provides a kind of injection pipeline muffler of dust pelletizing system.The utility model includes injection pipeline, mineral wool layer is provided with outside the injection pipeline, 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 noise during blowing is effectively reduced in the utility model, while will not influence 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 preparation technical field.
Background technique:
Pulse blowing bag type dust precipitator is a kind of the most commonly used deduster, and the course of work is when dusty gas is by entering the wind
Mouth enters deduster, initially strikes the inclined plate and baffle among inlet and outlet, and air-flow, which just turns to, flows into ash bucket, while air velocity
Slow down, 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 gas of ash bucket
The outer surface of filter bag, purified gas are then rolled over and be trapped in upwardly through the internal filter bag dust equipped with metallic framework to stream
Into baghouse top clean room, it is pooled to air outlet discharge, during dusty gas is purified by filter bag, with the time
Increase and the dust that is attached on filter bag of product is more and more, increase resistance of the filter bag, cause to handle air quantity and gradually decrease, is normal work
Make, to control resistance (the 140-170 millimeter of water) in a certain range, it is necessary to deashing be carried out to filter bag, by pulse control when deashing
Each control valve unbalanced pulse valve of instrument sequence trigger switch processed, the compressed air in gas bag is by each hole of injection tube through Wen's pipe inspection to each phase
In the filter bag answered, filter bag moment sharply expands, and product is made to be attached to the dust releasing of filter bag surface, and filter bag is regenerated.Dust lower clearly
Ash bucket is fallen into, body is discharged through dust removing system.Thus make the long-pending dust being attached on filter bag pulse jetting deashing periodically, make to purify
Gas is normal through guarantee dust pelletizing system operation.
During blowing, noise caused by air-flow is very big, seriously affects working environment, is directed to the noise reduction of pipeline at present
Device, which is generallyd use, is arranged in form inside pipeline for silencing means, and the effect of silencer is exactly to pass through reduction, decaying exhaust
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 blowing, to influence to be blown effect.
Summary of the invention
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 blowing is reduced, while will not influence 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,
The mineral wool layer space outside is provided with fixed ring, the fixed ring by damping device connected with outer casing, the shell with
Sound-absorbing material layer is filled between the 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.
The utility model has the advantages that
1. the present invention uses the silencing means of pipeline peripheral hardware, traditional pipe muffler is avoided with shunt pressure, reduce,
The pulsation for the pressure at expulsion that decays while sound-absorbing effect is good, does not influence to be blown to eliminate influence of the noise to injection pipeline air pressure
Effect, it is stable and reliable in work.
2. sound-absorbing material layer of the invention uses flame retardant polyurethane sound-absorbing material, high pressure gas and pipe during blowing are avoided
Road friction generates a large amount of heat and sound-absorbing material is caused to burn, highly-safe.

Specific embodiment
With reference to embodiment, the present invention is furture elucidated, it should be understood that following specific embodiments are only used for
It is bright the present invention rather than limit the scope of the invention.
As shown in Figure 1, the injection pipeline muffler of the dust pelletizing system of the present embodiment, including injection pipeline 1, the injection tube
Mineral wool layer 2 is provided with outside road, the mineral wool layer space outside is provided with fixed ring 3, and the fixed ring passes through damping
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 blowing
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 modifications and embellishments should also be considered as the scope of protection of the present invention.
