Abstract
The utility model belongs to the technical field of the gas evacuation of gas purification factory, concretely relates to gas purification house axial -flow fan variable frequency speed governing(VFSG) evacuating device, characterized by, one section adsorption tower passes through the pipeline to be connected with high -efficient water fog generator, and high -efficient water fog generator is connected with the valve, and the valve is connected with axial -flow fan, and axial -flow fan is connected with high -efficient dehydrator, and high -efficient dehydrator is connected with the valve, and the valve is connected with the two -stage process adsorption tower. The utility model discloses shortcoming such as improved the low concentration gas purification water ring vacuum pump of factory inefficiency, the power consumption is big, vacuum is low, the noise is too big, with low costs, the installation is simple and easy, can improve the gas factory's benefit of purifing.
Description
Technical field
The utility model belongs to gas purification factory gas vacuum pumping technology field, is specifically related to a kind of gas purification station-service tube axial fan speed control by frequency variation vacuum extractor.
Background technology
The low concentration gas carried out at present is purified the technological operation such as to vacuumize utilizing in project and usually adopt water ring vacuum pump to carry out low-concentration methane gas conveying or adsorption tower.Low-concentration methane gas due to extraction is the mixture of methane and air, there is inflammable and explosive characteristic, comparatively large on safety in production impact, the hazardous condition that the electrostatic produced in course of conveying, spark etc. cause, will the transmitting power equipment of the low dense methane gas of careful selection.The water ring vacuum pump adopted in Practical Project construction can meet safety in production needs substantially, but from the situation of project investment and project actual motion, adopts water ring vacuum pump to carry out vacuum pumping to device and mainly contain following shortcoming:
1) efficiency is low, generally about 30%, can reach 50% preferably.
2) low vacuum, this is not only because be subject to structural restriction, the more important thing is the restriction by working fluid saturation vapour pressure.Use water as working fluid, ultimate pressure can only reach 2000 ~ 4000Pa, makes working fluid with oil, can reach 130kPa.
3) noise is large.
Summary of the invention
The purpose of this utility model overcomes above-mentioned deficiency, provides a kind of gas purification station-service tube axial fan speed control by frequency variation vacuum extractor.
The utility model solves the technical scheme that its technical problem adopts: a kind of gas purification station-service aerofoil fan speed control by frequency variation vacuum extractor, comprise one section of adsorption tower 1, tube axial fan 2, two sections of adsorption towers 3, efficient mist producer 4, efficient dehydrator 5 and valve 6, it is characterized in that, one section of adsorption tower 1 is connected with efficient mist producer 4 by pipeline, efficient mist producer 4 is connected with valve 6, valve 6 is connected with tube axial fan 2, tube axial fan 2 is connected with efficient dehydrator 5, efficient dehydrator 5 is connected with valve 6, valve 6 is connected with two sections of adsorption towers 3.
The beneficial effects of the utility model are, improve the shortcomings such as low concentration gas purification factory Water-ring vacuum pump efficiency is low, power consumption large, low vacuum, noise are excessive, particularly in running cost, tube axial fan is more much lower than water ring vacuum pump, and tube axial fan is installed simple and easy, equipment investment cost also will be saved a lot.Tube axial fan is used for the production of low concentration gas purification factory, must bring the increase of purification factory economic benefit.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the simplified schematic diagram of a kind of gas purification of the utility model station-service tube axial fan speed control by frequency variation vacuum extractor.
In figure:
1. one section of adsorption tower, 2. tube axial fan, 3. two sections of adsorption towers, 4. efficient mist producer, 5. efficient dehydrator, 6. valve.
Embodiment
See Fig. 1, a kind of gas purification station-service tube axial fan speed control by frequency variation vacuum extractor that the utility model proposes, comprise one section of adsorption tower 1, tube axial fan 2, two sections of adsorption towers 3, efficient mist producer 4, efficient dehydrator 5 and valve 6, it is characterized in that, one section of adsorption tower 1 is connected with efficient mist producer 4 by pipeline, and efficient mist producer 4 is connected with valve 6, valve 6 is connected with tube axial fan 2, tube axial fan 2 is connected with efficient dehydrator 5, and efficient dehydrator 5 is connected with valve 6, and valve 6 is connected with two sections of adsorption towers 3.
One section of adsorption tower 1 is connected with tube axial fan 2 by pipeline, in the import of tube axial fan 2, efficient mist producer 4 is installed, tube axial fan 2 and efficient mist producer 4 intermediate conduit arrange valve 6, tube axial fan 2 is connected with two sections of adsorption towers 3 by pipeline, arranges efficient dehydrator 5 in the middle of connecting tube.During normal production, low-concentration methane gas is extracted out from one section of adsorption tower 1 by tube axial fan 2, and efficient mist producer 4 is set on pipeline carries out one section of purification after gas gas and water smoke blending, the methane gas after blending is sloughed through efficient dehydrator 5 and to be entered two sections of adsorption towers 3 after moisture content and again carry out purification and produce.If when needing to carry out vacuum pumping when producing, close one section of adsorption tower 1 imported valve 6.In like manner, when two sections of adsorption towers 3 need to carry out vacuum pumping, can arrange and export identical equipment configuration with one section of adsorption tower 1, also can be connected by pipeline with one section of adsorption tower 1, share set of device.
The utility model takes into full account the need of production that gas purification factory vacuumizes, and is meeting under safety condition, has saved the fund cost of producing and has dropped into, can obtain larger raising simultaneously in economic benefit.
