Abstract
The utility model discloses a but fan system that is used for refined sour apparatus for producing of noise reduction has roots's fan, and roots's fan is installed on the fluid pipeline, its characterized in that being connected with the pipe of eliminating the noise on the fluid pipeline, the diameter of the pipe of eliminating the noise is greater than the diameter of fluid pipeline, the intraductal central point that eliminates the noise put be equipped with first pore, first pore laid the second pore all around, there is woven wire in first pore and second pore packing on every side. Evenly distributed has and inhales the aperture that shakes on the lateral wall in first pore and second pore. The utility model discloses the beneficial effect who has: choose for use porous pipe to add the woven wire amortization to solving the noise part, make the noise drop to within the national standard scope. Use dry air as the air supply, to rotating the shaft seal part atmoseal, correctly select the sealing ring material simultaneously, lengthened life, reduced maintenance cost and maintenance frequency.
Description
Technical field
This utility model is related to sulphuric acid plant correlative technology field, specifically a kind of to reduce being used for for noise
The blower fan system of refined acid process units.
Background technology
Roots blower is the key equipment of conveying gas in refined acid production equipment, but existing roots blower, mainly
It is directed to convey based on air, and in sulphuric acid process, in sulfuric acid absorption tower exit gas, carries micro SO2、
SO3With sour foam, this has a significant impact to roots blower operating, if these enter the wallboard of roots blower with corrosive substance
Both sides rotary shaft air seal component meeting heavy corrosion bearing, air seal component, travelling gear, and make lubricating oil in the fuel tank of wallboard both sides
Acidifying is rotten, and oil seal washer is damaged.More than have problems, make that roots blower service life is short and maintenance cost is high.In addition, Roots's wind
The noise that machine is produced is also a very big problem, noise severe overweight when equipment runs.
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, there is provided it is a kind of reduce noise for essence
The blower fan system of antacid process units.
In order to reach the purpose of this utility model, technical scheme is as follows：
A kind of blower fan system for refining acid process units for reducing noise, with roots blower, roots blower peace
Be mounted on fluid line, it is characterised in that on fluid line, be connected with hush tube, hush tube it is straight with diameter greater than fluid line
Footpath, the center in hush tube are provided with the first duct, the surrounding in the first duct and are laid with the second duct, the first duct and second
Metal gauze is filled with around duct.
Preferably, 2 times of a diameter of fluid line diameter of hush tube.
Preferably, absorbing hole is evenly distributed with the side wall in the first duct and the second duct.
Preferably, roots blower has rotary shaft, is arranged with protective shaft sleeve, elastic graphite tetrafluoro circle, rotary shaft in rotary shaft
Side sheet be provided with sealing gland passage, connected with compressed air piping with production system pneumatic control valve with pipeline on sealing gland passage
Connect, compressed air piping provides compressed air, and the pressure of compressed air into sealing gland passage more than the pressure in sealing gland passage
The operating pressure of power and roots blower.
This utility model has the advantage that：
Add metal gauze noise reduction for noise components are solved from antipriming pipe, within the scope of making noise be down to national standard.
Drying compressed air with production system gas control valve as source of the gas, to rotating shaft-seal part sealing gland, while correct select
Seal ring material, extends service life, reduces maintenance cost and frequency of maintenance.

Specific embodiment
This utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1-Fig. 7, a kind of blower fan system for refining acid process units for reducing noise, roots blower
With rotary shaft 1, protective shaft sleeve, elastic graphite tetrafluoro circle 2 in rotary shaft 1, is arranged with.1 side sheet of rotary shaft is provided with sealing gland and leads to
Road 3, is connected with production system pneumatic control valve compressed air piping 4 with pipeline on sealing gland passage 3, production system compressed air
Pipeline 4 provides compressed air into sealing gland passage 3, and guarantees the work pressure of the pressure slightly larger than roots blower of compressed air
Power, when with SO2、SO3During with sour foam gas flow rotary shaft, these sour gas can be blocked by the bigger compressed air of pressure,
Rotating shaft-seal component, bearing etc. is avoided to be corroded.
Roots blower is arranged on fluid line 5, therefore is mounted with hush tube 6 on fluid line 5 due to noise greatly,
Center in hush tube 6 is provided with the first duct 63, the surrounding in the first duct and is laid with the second duct 62, the first duct and
Metal gauze 61 is filled with around two ducts.The diameter with diameter greater than fluid line 5 of hush tube 6, it is preferable that noise elimination pipe diameter
About 2 times of fluid line diameter, in gas and sound inflow hush tube 6, branch in the first duct and the second duct, make an uproar
Sound is progressively absorbed by metal gauze through absorbing hole 64, within the scope of being down to national standard.In order to reach more preferable soundproof effect,
On the side wall in the first duct and the second duct, absorbing hole of uniformly gathering, noise are inhaled by metal gauze behind absorbing hole 64 rapidly
Receive.
Finally it should be noted that：Above example only not limits this utility model and is retouched to illustrate this utility model
The technical scheme stated, therefore, although this specification this utility model is had been carried out with reference to each above-mentioned embodiment it is detailed
Illustrate, but, it will be understood by those within the art that, still this utility model can be modified or be equal to replace
Change, and all are without departing from technical scheme and its improvement of spirit and scope of the present utility model, which all should cover new in this practicality
In the right of type.
