Description
Affiliated technical field
The present invention relates to a kind of blower fan, the Fan made from titanium that uses in especially a kind of chlor-alkali production.
Background technique
At present, the blower fan that China uses in chlor-alkali production in some chemical plant, the sealing requirements strictness does not allow chlorine to external leakage in operation process.So the sealing kind is a lot, shaft sealing is arranged, sealing effect is bad, and positive confinement is arranged, and as float ring seal, but this seal arrangement costs an arm and a leg, by a cover instrument and meter for automation control.On petrochemical compressor, often use, inapplicable to the blower fan that uses in the chlor-alkali production, uneconomical.In addition, the blower fan that use in some chemical plant is Japanese import, but efficient is low, energy consumption height, cost height.
Summary of the invention
In order to solve the problem of above-mentioned existence, the invention provides that chlorine transmits reliable safety in a kind of chlor-alkali production technological process, prevent the Fan made from titanium that leaks and corrode.
Concrete technological scheme is as follows: a kind of Fan made from titanium, comprise cross over pipe (1), intake grill group (3), casing (7), impeller (4), axle (10), axle sleeve (9), shaft end seal (16), transmission group (11), coupling (13), motor (14), support (15), exhaust outlet (17), put dirty pipe (18), it is characterized in that on cross over pipe (1) and casing (7) hub disk, being connected to balance tube (6); In balance tube (6) stage casing valve (5) being housed is the switch of balance tube; On axle sleeve, be furnished with water-cooled Stuffing box (8), labyrinth sealing circle (2) be set at intake grill group place; Respectively establish a thermometer socket (12) at transmission group (11) two ends.
Compare with prior art, the present invention adopts said structure, has the following advantages:
1) good airproof performance
Shaft sealing and system sealing.Shaft end seal and axle sleeve O type seal ring seal are adopted in shaft sealing; System sealing adopts water-cooled Stuffing box and the sealing of labyrinth sealing circle.Shaft end seal is a titanium blower fan structure commonly used.The water-cooled Stuffing box puts intake pipe and the outlet pipe that symmetrical distribution is set outward.The seal cage intake pipe directly leads to seal cage and filler place, forms moisture film herein and plays sealing and water-cooled lubrication.Be welded with a boss in impeller shroud bottom, matching with the labyrinth sealing circle seals and good sealing effect.
2) efficient height
This type of blower fan that Japan produces can be used for producing, but efficient is low, the energy consumption height.Efficient height of the present invention, energy-conservation.By following contrast table as seen, under same rotational speed, obtain identical aeroperformance, Japan's draught fan impeller diameter is bigger 1.32 times than this Fan made from titanium, Fan made from titanium efficient height of the present invention is described, blade shape changes many circular curves into by single circular curve in addition, has also improved efficient.
| Rotating speed r/min | Outlet pressure kPa | Impeller diameter mm | Blade shape | Efficient % | |
| Japan | 2910 | 21 | 1016 | Single circular arc | 65 |
| The present invention | 2970 | 21 | 770 | Many circular arcs | 72 |
3) corrosion-resistant
Chlorine is strong to common metal corrosivity, adopts the titanium material for the parts that contact with chlorine.Axle is the 45# steel, need prevent the corrosion of axle with titanium system shaft end seal and axle sleeve O type seal ring seal.
Cross over pipe of the present invention, intake grill group, casing, impeller, balance tube, valve, Stuffing box (gland is a stainless steel), labyrinth sealing circle, axle sleeve, shaft end seal, exhaust outlet, put dirty pipe etc., adopt industrially pure titanium (TA2) and titanium alloy (axle sleeve TC4) made, good corrosion resistance has increased substantially service life of equipment.It is not only anti-corrosion but also wear-resisting that axle sleeve adopts titanium alloy (TC4) to make.
4) the unit running is safe and reliable, meets technical order, can keep long-time running, and running can reach more than 8000 hours continuously.
The present invention meets the aeroperformance requirement of chloralkali process process, and technical order is as follows:
| Medium | Wet chlorine |
| Gas density | 2.6kg/m 3 |
| Intake temperature | 40℃ |
| Suction pressure | -6.0kPa |
| Go out atmospheric pressure | 21kPa |
