Abstract
The present invention provides a sulfuric acid centrifugal blower for a plateau, which relates to the sulfuric acid centrifugal blower which is suitable for plateau sections. The present invention is provided with a left bearing box, a right bearing box, a blower casing, a sliding bearing and a rotor set; a sealing shaft sleeve, two sets of impellers and a balancing disc are sheathed on a main shaft of a rotor. An inlet ring is riveted with a front disc for impellers, and a rear disc for impellers is riveted with a shaft disc; blades are welded into integration with the front disc for impellers and the rear disc for impellers. When the present invention is adopted, after sulfuric acid gas is compressed by one impeller, the sulfuric acid gas enters another impeller through a baffle to be compressed for the second time, and then, the compression ratio reaches 1.45 to 1.60; thus, the present invention can satisfy requirements of acid manufacturing technological processes with high pressure requirements in plateau sections or plain sections. The outlet angle of each impeller blade of the present invention is from 55 degrees to 60 degrees, the shaft diameter of the main shaft of the rotor is more than 100mm, and the outer diameter of the shaft sleeve is more than 270mm. The impellers, the blades, the shaft disc and the inlet rings of the impellers are made of acid-proof materials, and thus, the influence of attachments on rotor balance can be reduced to enable the blower to normally operate. The present invention has the advantages of simple structure, convenient operation and maintenance, low noise, low investment cost and low product cost.
Description
Technical field
The present invention relates to a kind of sulfuric acid centrifugal blower, be specially the sulfuric acid centrifugal blower that suits in the plateau section use.
Background technique
In the plateau section, because atmospheric pressure is low, when blower fan reaches same boosting, it is high that the compression ratio of the blower fan that use its compression ratio and plains region is wanted, that is to say that a same typhoon machine is used for the voltage rise that voltage rise that the plateau section produces is lower than when being used for the plains region to be produced.At present, in the acid-making process flow process of plateau section or plains region that pressure is had relatively high expectations, the sulfuric acid blower generally adopts the single-stage high-speed blower, compression ratio is between 1.45-1.63, single-stage low speed (3000r/min following) sulfuric acid blower does not then reach above-mentioned compression ratio, does not satisfy the plateau section or the requirement of the acid-making process flow process of plains region that pressure is had relatively high expectations.Two-stage low speed blower, the main shaft 100-220mm of rotor, the external diameter 240-330mm of axle sleeve, rotor set is perishable, owing to can't resolve corrosion problems and adhesion problem makes the rotor disequilibrium.High-speed fan complex structure, Operation and Maintenance bother, noise is big, cost of investment is high.
Summary of the invention
Purpose of the present invention aims to provide a kind of can avoiding and makes the unbalanced problem of rotor because of corrosivity and bonding, the sulfuric acid centrifugal blower for plateau of simple in structure, simple to operate, high pressure, low noise, two-stage low speed.
The implementation of the object of the invention is, sulfuric acid centrifugal blower for plateau, left side casing 4 fuses with right casing 6, in the middle of dividing plate 5 is positioned at, left bearing case 1, right bearing case 8 respectively with left casing 4, right casing 6 is connected, left side sliding bearing 2, right sliding bearing 7 is placed in left bearing case 1 respectively, in the right bearing case 8, rotor set 3 two ends are by left sliding bearing 2, right sliding bearing 7 supports, be with sealing axle sleeve 10 on the rotor main shaft 9, axle sleeve 11, impeller 12, axle sleeve 13, impeller 14, Balance disc 15, sealing axle sleeve 16, import circle 17 is riveted together with impeller shroud 18, impeller hub disk 19 is riveted together with reel 20, the shroud 18 of blade 22 and impeller, and hub disk 19 is integrally welded.
After adopting sulfuric acid gas of the present invention through impeller 12 compressions, enter impeller 14, twice compressions, make compression ratio reach 1.45-1.60, to satisfy the requirement of the acid-making process flow process of plateau section or plains region pressure being had relatively high expectations through dividing plate.
The shroud of impeller of the present invention, hub disk, blade adopt acid-resistant stainless steel, the import circle of impeller, and reel adopts the high strength alloy steel forgings, and the surface is coated with acid resisting material, has solved the bonding attachment point problem that etching problem and corrosion back form; The molded lines of blade is similar to board-type, can reduce bonding; The main shaft overstriking, the external diameter of axle sleeve strengthens, and the quality of rotor increases, and has reduced the influence of attachment to balancing rotor, and blower fan is normally moved.
The present invention compares with high speed sulfuric acid blower fan, and simple in structure, convenient operating maintenance, noise are low, cost of investment and product cost are low.

Embodiment
With reference to Fig. 1, left and right bearing housing and 1,8 is connected with left and right casing 4,6 respectively, the left and right sliding bearing 2,7 of support rotor group 3 is placed in respectively in the left and right bearing housing, with reference to Fig. 2, is with sealing axle sleeve, axle sleeve, two groups of impellers, Balance disc 15 on the rotor main shaft 9.With reference to Fig. 3, import circle 17 is riveted together with impeller shroud 18, and impeller hub disk 19 is riveted together with reel 20, the shroud of blade 22 and impeller, and hub disk is integrally welded.
Use when of the present invention, sulfuric acid gas is entered by the intake grill on the left casing 4, after impeller 12 compressions, by dividing plate 5 gas is imported impeller 14 compression for the second time, twice compression makes compression ratio reach 1.45-1.63, collects the back through right casing 6 chambers annular and discharges from exhaust outlet.Compressed-air actuated compression ratio reaches 1.45-1.63, can satisfy the requirement of the acid-making process flow process of plateau section or plains region pressure being had relatively high expectations.
The present invention has adopted following measures:
The shroud 18 of impeller, hub disk 19, blade 22 adopt acid-resistant stainless steel, owing to adopted stainless steel, do not have corrosion problems, the bonding attachment point that does not also exist impeller corrosion back to form;
The exit angle of impeller blade is 55-60 °, and this large outlet angle makes the approximate board-type of the molded lines of blade, can reduce bonding;
The import circle 17 of impeller, reel 20 adopts the high strength alloy steel forgings, and the surface is coated with acid resisting material, but corrosion protection;
The shroud of blade 22 and impeller, hub disk is integrally welded, and the welding seam grinding of welding part is smooth, reduces the bonding attachment point:
The main shaft overstriking of rotor is to 100-255mm, and the external diameter of axle sleeve is increased to 270-390mm, and the quality of rotor is increased, even a spot of attachment is arranged like this, also its influence to balancing rotor can be reduced to bottom line, the unlikely operation that influences blower fan.
Compare with high speed sulfuric acid blower fan, two-stage low speed sulfuric acid blower fan, simple in structure, convenient operating maintenance reduces noise, Protection of the environment. A high-speed fan price is more than 1,000,000 yuan, and reaches the present invention of identical performance, price less than 500,000 yuan, can save cost of investment and product cost more than 50%.
