Abstract
The invention aims to provide an impeller assembly for a chlorine gas compressor. The impeller assembly for the chlorine gas compressor is characterized in that the impeller assembly is formed by assembling and connecting a big impeller and a small impeller; the big impeller and the small impeller are both provided with twenty vanes; the vanes of the big impeller and the vanes of the small impeller are recurved; the recurved angle of each big impeller vane R99 is 6.5 DEC; the recurved angle of each small impeller vane is 5 DEC; mounting positions of the big impeller vanes and the small impeller vanes are consistent and uniform; the two impellers are connected and tightened with thorough a bolt; then, the excircle at the impeller joint is further arranged to be an inner bore inverted groove. The impeller assembly for the chlorine gas compressor can meet requirements of the large-scale chlor-alkali industry; the operation time is long; the energy consumption is saved; the maintenance is convenient; the novel double-body impeller provided by the invention is small in volume, high in lift head, and lower in energy consumption; moreover, precision casting technology is adopted to replace the original sand casting technology, so that the vanes are enabled to be thinner and the operation is enabled to be smoother and steadier.
Description
Technical field
The present invention relates to a kind of matching component of chlorine gas compressor, is specifically a kind of chlorine gas compressor impeller assembly.
Background technique
Chlorine gas compressor is for aspirating or compressing not the gas-10 ℃～60 ℃ of scopes containing solid particle, water insoluble, temperature, be applicable to the industries such as chemical industry for making chlorine and alkali, polysilicon industry and papermaking, food, weaving, metallurgy, coal, petrochemical industry, do vacuum dehydration, vacuum drying, pumps inflammable, explosion hazard gases and toxic and harmful.Wherein the model utility of the patent No. 91211654.4 discloses a kind of piston type chlorine compressor, and it is the key equipment of realizing chlorine normal-temperature liquefaction process route.It has complete in external leakage, the feature such as corrosion-resistant, free from environmental pollution, energy-conservation.Bellow type rubber axis end sealing device can make the gas leaking concentrate in bellows, and the gas in its bellow type rubber sealing device can communicate with the air inlet pipeline of certain one-level cylinder, also can communicate with the balancing volume of cylinder, and not contact with ambient air.The model utility of the patent No. 200620093940.0 discloses a kind of chlorine centrifugal compressor, comprise base, motor, volute, speed increaser, lubricating fitting, heat exchanger, motor is installed on base, speed increaser, lubricating fitting, heat exchanger, motor is connected with speed increaser by shaft coupling, speed increaser two ends are respectively provided with a volute, left side volute is connected with heat exchanger, lubricating fitting is provided with the pipeline road of supplying with each lubricating component lubricant oil, heat exchanger is connected with lubricating fitting by heat exchanger oil pipe, its technical characterstic is: on the radial bearing at speed increaser two ends, high speed shaft is installed, high speed shaft both sides are provided with seal arrangement, high speed shaft end is provided with impeller.Advantage of the present utility model is: project organization is compact, and efficiency is high, can make unit long-period stable operation, and unit operation cost is low.Can obviously improve operating environment and plant environment.
Yet, in chemical industry for making chlorine and alkali industry, in production of caustic soda manufacturing process, often adopt liquid-piston compressor.Liquid-piston compressor impeller mostly is monomer-type, and unitary impeller volume is large, lift is low, energy consumption is higher; Therefore need to be improved.
Summary of the invention
The object of the invention is to provides a kind of chlorine gas compressor impeller assembly at this; Meet large-scale chlorine industry needs, long operational time, energy efficient, easy to maintenance.Novel binary impeller, under same duty parameter, volume is little, lift is high, Energy Intensity Reduction.Meanwhile, adopted the technique of precision casting to substitute original sand casting technology, made blade thinner, moved also more steady.
The present invention realizes like this, construct a kind of chlorine gas compressor impeller assembly, it is characterized in that: impeller assembly is formed by connecting by large and small two impellers combination, the blade of large small impeller is 20, is all rear bending, and after large impeller blade R99, bending angle is 6.5 °, 5 ° of small impeller blade R56 palintropes, consistent alignment is installed in size impeller blade position, and two impellers connect and tighten with bolt, then by the outer fenestra endoporus adverse slope mouth of impeller joint.
According to chlorine gas compressor impeller assembly of the present invention, it is characterized in that: large and small two impellers are that stainless steel casting forms; Make blade thinner, move also more steady.
Binary chlorine gas compressor impeller, rotating speed: 1480 rpm; Pressure: 1.2 MPa; 60 ℃ of temperature: <; Medium: 98% concentrated sulphuric scid, 96% chlorine.Through running more than 2 years, reach advanced world standards.
The invention has the advantages that: novel binary impeller of the present invention, under same duty parameter, volume is little, lift is high, Energy Intensity Reduction.Meanwhile, adopted the technique of precision casting to substitute original sand casting technology, made blade thinner, moved also more steady.
